Introduction

Input flood is a technique used in second language acquisition (SLA) in which learners are repeatedly exposed to a specific linguistic feature embedded naturally in comprehensible input. Unlike traditional grammar teaching that isolates and explains rules, input flood saturates learners with high-frequency occurrences of a target form across meaningful contexts. Over time, this facilitates both unconscious acquisition and eventual accurate production. As learners internalise these structures through multiple exposures, they develop both greater receptivity to form and more intuitive usage.

In recent years, input flood has received growing attention not just as a standalone instructional tool but as a foundational principle to be integrated into a broad array of pedagogical approaches. In this article, I explore the theoretical underpinnings, empirical evidence, practical advantages, and synergistic effects of input flood with related instructional techniques such as narrow reading/listening, processing instruction, structural priming, and its central role in my own EPI (Extensive Processing Instruction) approach.

Theoretical Foundations

Input flood draws its conceptual foundation from Krashen’s (1982) Input Hypothesis, which holds that acquisition occurs when learners are exposed to language that is comprehensible but slightly beyond their current level (i+1). According to Krashen, such exposure must be extensive, contextualised, and focused more on meaning than form. Input flood satisfies these criteria by embedding repeated target structures within rich, meaningful contexts.

Additionally, usage-based theories of language acquisition (Ellis, 2002; Tomasello, 2003) support the role of frequency and distribution in shaping mental grammar. Learners abstract rules from repeated input—a process known as entrenchment—and begin to notice regularities without overt instruction. Ellis (2005) further notes that learners develop implicit grammatical knowledge more effectively through frequency-based exposure than through metalinguistic explanation. These foundational principles are also echoed in my EPI framework (Conti & Smith, 2021), where input flood is employed as a core tool to facilitate structured exposure to syntactic patterns across all modes of input.

Empirical Support for Input Flood

Research into input flood demonstrates its potential to promote robust form acquisition. Trahey and White (1993) found that French-speaking ESL learners showed significant improvements in adverb placement after exposure to input floods, even without any explicit instruction. Their study provided early evidence that frequency and input salience can alter learner output.

Doughty and Varela (1998) examined the use of input flood in combination with task-based interaction and corrective feedback, showing substantial gains in learners’ use of the English past tense. Similarly, Hernández (2008) demonstrated that input flood delivered via reading and listening texts targeting the Spanish subjunctive resulted in significant improvements in learner accuracy and recognition.

Studies by Han, Park, and Combs (2008) and others confirm that when relative clauses or tense forms are embedded repeatedly in context, learners show both immediate and delayed gains in their comprehension and production. These effects have also been replicated across multiple learner age groups and instructional settings, suggesting wide applicability. Within my EPI model, input flood is operationalised through sentence builders, L.A.M. (listening-as-modelling) tasks, narrow reading texts, and retrieval-based repetition—designed to maximise cognitive uptake of key patterns.

Benefits of Input Flood

1. Implicit Learning Support: Repeated exposure to linguistic features in input enables learners to acquire grammatical forms subconsciously (Hulstijn, 2005). This mirrors how first languages are learned and helps avoid cognitive overload.
2. Low Cognitive Load: By bypassing the need for conscious form analysis, input flood reduces processing burden and facilitates more natural uptake (Sweller, 1994).
3. Durability: Acquisition through input flood tends to result in longer-lasting knowledge compared to rule memorisation or output drills, particularly when exposure is meaningful (Ellis, 2005).
4. Engagement and Motivation: When input flood is implemented using authentic and engaging materials—such as narratives, dialogues, and songs—it increases learner motivation and contextualises grammar in communicative use.
5. Accessibility Across Levels: Unlike grammar instruction requiring a threshold of metalinguistic knowledge, input flood can be implemented with learners of all proficiency levels.
6. Facilitates Noticing: Learners become sensitised to recurring forms, which promotes deeper processing and eventual rule abstraction.
7. Structured Implementation within EPI: In my EPI framework, input flood is meticulously sequenced across layers of receptive and productive practice, ensuring multiple memory traces are established before output is expected.

Conclusion

Input flood is a powerful, flexible, and research-validated method for supporting naturalistic language acquisition in the classroom. It offers a low-stress, high-exposure route to acquisition that aligns with core cognitive and linguistic theories. While effective on its own, input flood’s true potential is realised when it is synergised with input enhancement, processing instruction, narrow input strategies, and structural priming.

In my EPI framework, input flood is the backbone of receptive and early productive stages, designed to create robust memory traces through exposure, modelling, repetition, and retrieval. When implemented thoughtfully and supported by purposeful output tasks, input flood can transform the classroom into a rich ecosystem for language acquisition—promoting fluency, accuracy, and long-term retention. Teachers seeking to align instruction with second language acquisition research would do well to embrace this principle as a cornerstone of their practice.

Why EPI

EPI is a pedagogical approach that places processing at the centre of language learning. Steeped in sound SLA tehory and research, it promotes deep, repeated exposure to meaningful input and structured output activities designed to progressively build fluency.

Rather than rushing into production, EPI sequences learning through carefully scaffolded stages that support long-term acquisition. It has been widely adopted across classrooms in the UK, Australia, and beyond for one key reason: it works.

With EPI, learners:

• Build automaticity through repetition with variation
• Develop grammatical competence in context
• Gain confidence before being expected to speak or write
• Experience success in manageable, motivating steps
• Engage meaningfully with tasks that match their level and cognitive maturity

EPI also represents a meaningful shift away from shallow, performance-driven tasks towards activities that promote depth of processing and long-term retention. The approach encourages students to notice language features, retrieve vocabulary with support, and gradually move from supported rehearsal to spontaneous communication.

Theories and Research Behind EPI

My model is not only intuitive—it’s deeply rooted in some of the most influential theories in second language acquisition. EPI draws strength from a confluence of research traditions in cognitive psychology, applied linguistics, and educational neuroscience. What makes EPI particularly distinctive is the way it operationalises these theories into teachable routines and sequences that address both comprehension and production.

At the core is the skill-acquisition theory (Anderson), which posits that language knowledge must be proceduralised through repeated, meaningful practice. This principle is echoed in the carefully graduated steps of the MARS EARS cycle, which begin with heavy scaffolding and gradually foster autonomy and spontaneity.

EPI also incorporates elements of VanPatten’s input processing theory, which highlights the cognitive limitations learners face when trying to process form and meaning simultaneously. In EPI, both listening and reading are approached as modelling experiences — not comprehension tests — allowing students to absorb form-function relationships through repeated, comprehensible input.

John Field’s process-based approach to listening adds further support, positioning listening as an active, trainable skill. EPI’s Listening as Modelling phase aligns with this view by focusing on decoding, segmentation and phonological pattern recognition rather than mere gist-taking.

The Noticing Hypothesis (Schmidt) is reflected in the inclusion of awareness-raising tasks that follow the modelling phase. These tasks draw learners’ attention to specific grammatical or lexical patterns they have already encountered in context, preparing them for more autonomous production later.

From a cognitive angle, working memory theory (Baddeley) justifies EPI’s emphasis on recycling, repetition, and low cognitive-load activities in the initial stages. Tasks are carefully designed to optimise processing and retention by staying within learners’ cognitive capacity.

The approach also draws on Michael Hoey’s Lexical Priming theory, which underscores the role of repeated, context-rich exposure in vocabulary acquisition. EPI ensures high-frequency items and chunks reappear across lessons in familiar but varied linguistic environments.

Krashen’s comprehensible input hypothesis informs the initial modelling and receptive phases of EPI. However, unlike approaches that stop at input, EPI builds systematically toward output, ensuring that learners are prepared to speak and write with increasing spontaneity.

Significantly, EPI integrates Swain’s concept of pushed output by incorporating activities that challenge learners to stretch their language resources. Structured and semi-spontaneous tasks gradually reduce support while increasing communicative demands.

Finally, Paul Nation’s fluency training principles are central to the final phases of the MARS EARS cycle. Repetition with variation, time constraints, and the use of familiar language all serve to automate recall and build processing speed.

Here is a breakdown of the major research foundations EPI draws upon:

Introduction

Learning a language is one of the most enriching things a person can do — and also one of the most misunderstood. In an age of language apps, TikTok polyglots, and soundbite promises of “fluency in 30 days,” it’s easy to lose sight of the reality: becoming proficient in a second language takes time, consistency, and the right conditions. For learners in school systems like the UK, this journey is even more complex, shaped by external constraints and the inherent properties of the target language. So how long does it really take to learn a language? And why do some languages seem much harder than others?

This article draws on research from the Foreign Service Institute (FSI), CEFR, and classroom-based studies to explore what affects the pace of language acquisition. It also offers a grounded, realistic picture of what learners and teachers can expect — particularly in contexts where input is limited and achievement targets are set high.

What Does “Proficiency” Really Mean?

Proficiency, in the context of language learning, is not a vague sense of “being good at it.” It refers to a learner’s ability to understand and use the target language accurately and fluently across listening, speaking, reading, and writing. Most countries and education systems in Europe (including the UK) define proficiency using the Common European Framework of Reference for Languages (CEFR), which spans six levels:

CEFR Level	Description	Estimated Guided Learning Hours
A1	Beginner: basic everyday expressions	90–100
A2	Elementary: simple tasks, routine exchanges	180–200
B1	Intermediate: deal with familiar topics	350–400
B2	Upper Intermediate: interact with fluency	500–600
C1	Advanced: complex ideas, nuanced discourse	700–800
C2	Mastery: near-native precision and style	1,000+

According to Council of Europe (2001) guidelines and subsequent classroom-based research (North, 2014), these estimates are based on well-structured and consistent instruction. In practice, real-world learners — especially adolescents in school systems — often take significantly longer due to fragmented exposure, limited hours, and inconsistent practice. 

In theory, reaching B1 level proficiency requires approximately 350–400 guided learning hours (Council of Europe, 2001). However, in England, current constraints in curriculum time, coupled with recent reforms such as the reduced lexical scope of GCSE word lists (e.g. the 2024 MFL Subject Content), mean that learners have access to far fewer vocabulary items than would typically be required to support full B1-level interaction.

If we consider that most students receive around 2.5 hours per week over five years of Key Stage 3 and 4 (roughly 36 weeks per year), this only amounts to around 450 contact hours — and that’s an optimistic estimate that doesn’t account for absences, disruptions, or limited practice time. Even with full attendance, much of this time is spent revisiting basic content, rehearsing exam techniques, and teaching to the test.

Research by Graham et al. (2017) and Mitchell & Marsden (2019) shows that in the current climate, learners in England rarely exceed A2, and only a small subset achieve even partial B1 functionality by the end of GCSE.

One important lens researchers use to evaluate developing proficiency — especially in speaking and writing — is the CAF framework, which breaks performance down into Complexity, Accuracy, and Fluency. Studies applying CAF (e.g., Housen, Kuiken & Vedder, 2012) have shown that genuine B1-level production requires a level of automaticity and flexibility rarely seen in GCSE learners, who are often trained in short, memorised chunks with limited scope for spontaneous, accurate, or complex output.

How Long Does It Typically Take?

The most widely cited estimates come from the Foreign Service Institute (FSI), which trained US diplomats in foreign languages and ranked languages into categories based on the average number of guided learning hours required to reach Professional Working Proficiency (B2–C1 on the CEFR scale) for English-speaking adults.

FSI Category	Language Examples	Hours to Proficiency
Category I – Easy	French, Spanish, Italian, Portuguese	600–750 hours
Category II – Moderate	German, Swahili, Indonesian, Malay	750–900 hours
Category III – Difficult	Russian, Turkish, Polish, Romanian, Greek, Hindi	1,100 hours
Category IV – Very Difficult	Arabic, Mandarin, Cantonese, Japanese, Korean	2,200+ hours

These figures are based on full-time, intensive study environments typical of diplomatic or military training — around 25 hours of instruction per week, plus self-study and immersion, over a period of several months to a few years. They reflect a scenario where language learning is the learner’s primary focus, and the teaching methods are structured, high-quality, and consistent.

In contrast, learners in school systems — like secondary students in the UK — operate under very different conditions. Time on task is far more limited, often fragmented, and diluted by competing curricular demands. As such, these FSI estimates should be interpreted as best-case scenarios rather than realistic expectations for the average school learner.

Moreover, the FSI’s classifications are based on distance from English and do not account for variables such as learner motivation, teaching quality, or access to authentic input — all of which have been shown to significantly influence rate of progress (Muñoz, 2014; Lightbown & Spada, 2013).

Taken together, the FSI framework is best viewed as a useful guideline for comparing relative difficulty, not absolute timelines. For most learners in non-immersive settings, the number of hours required to achieve the same levels of proficiency is likely to be significantly higher.

What Makes a Language Intrinsically Harder?

Not all languages are created equal in terms of learnability — especially for English speakers. Several linguistic and cognitive factors play a major role in determining how quickly a learner can internalise a new language system.

Orthographic Distance – How different is the writing system?

Languages like Mandarin, Arabic, and Japanese use writing systems that differ significantly from the Roman alphabet. Learning to decode and produce logographic characters (e.g. 汉字 in Chinese) or abjads (where vowels are omitted, as in Arabic) increases the cognitive load.

Phonological Complexity – How hard is it to pronounce and distinguish sounds?

Languages with a high number of phonemes, unfamiliar consonant clusters, or tonal variation can be harder to acquire. For instance, Mandarin Chinese has four lexical tones, meaning the pitch pattern of a syllable changes the word’s meaning. Meanwhile, Arabic includes sounds like the pharyngeal fricatives /ʕ/ and /ħ/ which don’t exist in English.

Morphological Complexity – How many forms do words take?

Highly inflected languages like Russian or Polish require learners to memorise numerous case endings, gender rules, and verb conjugations. This contrasts with relatively analytic languages like English or Mandarin, where word order plays a bigger role than word form.

Syntactic Distance – How different is the sentence structure from English?

Languages with subject-object-verb (SOV) word order, like Japanese and Korean, or those with flexible word order, pose difficulties for English speakers used to the relatively rigid subject-verb-object (SVO) pattern. Embedded clauses, topic-prominent constructions, and honorific systems further complicate the learner’s task.

Lexical Similarity – How much vocabulary is familiar?

Languages that share cognates with English (due to Latin or Germanic roots), like French or Spanish, offer a significant head start. In contrast, languages from different families — like Korean or Hungarian — offer few lexical connections and require learning thousands of entirely new word forms.

Environmental, Learner, Curriculum and Methodological Factors That Prolong the Process

Beyond the linguistic complexity of a given language, numerous external and internal factors significantly influence how long it takes to become proficient — often extending the process well beyond theoretical estimates.

Learning Environment

Many students in mainstream education are limited by the constraints of the school timetable. Language learning is typically allotted no more than two or three sessions a week, and even that is subject to cancellations, assessments in other subjects, or pastoral disruptions. Additionally, exposure to the language outside the classroom is often minimal, especially in predominantly monolingual environments like the UK, where daily encounters with the target language are rare.

Teaching Contact Time

Teaching contact time is arguably the most significant structural factor limiting progress in mainstream language classrooms. Research by Muñoz (2014) and Graham et al. (2017) shows that consistent, high-frequency exposure to the target language is essential for building automaticity and long-term retention. Yet in the UK, learners typically receive as little as two to three hours per week — far below the threshold required to consolidate grammar, expand vocabulary, and develop fluency. These limitations are compounded by frequent timetable interruptions, non-specialist teaching in earlier years, and limited opportunities for structured retrieval practice. In such low-input settings, progress is inherently slow and fragile unless significantly supplemented through immersion, digital exposure, or extracurricular reinforcement.

Learner Variables

Individual differences such as working memory, motivation, learning strategies, prior knowledge of other languages, and even learner beliefs about language learning (Dörnyei & Ushioda, 2011) play a significant role. Learners who are motivated, self-regulated, and have access to technology-enhanced tools progress more quickly than those with lower levels of engagement and confidence. However, most classroom learners remain largely dependent on the teacher and textbook.

Curriculum Design

In recent years, curriculum reforms have introduced more ambitious intentions (such as the MFL Pedagogy Review’s call for a ‘rich diet’ of language), but these often clash with restricted word lists, excessive focus on grammar manipulation, or high-stakes exam pressures. In practice, much teaching time is still devoted to exam rehearsal, leaving little room for meaningful communicative interaction or vocabulary expansion.

Methodology and Input

Finally, the method of delivery matters immensely. Approaches rooted in traditional PPP (presentation–practice–production) are less effective than those based on input-rich, communicative, or task-based instruction (Ellis, 2003). Learners need repeated exposure to comprehensible input, scaffolded output opportunities, and structured retrieval of key language forms. When methodology relies too heavily on isolated grammar exercises or rote translation, progression slows.

Teacher Expertise and Confidence

The skills and confidence of the teacher have a profound impact on the learner’s experience. Many secondary MFL teachers report gaps in their training — especially when it comes to spontaneous speaking, teaching phonics, and recycling vocabulary effectively (Tinsley & Doležal, 2018). When confidence is low, teachers may default to safer, less dynamic methods such as worksheets or rote grammar tasks, which limit opportunities for interaction and personalisation.

Assessment Systems and Accountability Pressures

The nature of assessment also plays a role. In the UK, GCSE and A-level exams remain heavily focused on discrete grammatical accuracy and tightly controlled writing tasks. This emphasis often narrows the scope of what is taught and assessed. As a result, authentic communication, fluency, and risk-taking — which are critical for long-term language development — are often deprioritised in favour of predictable exam outcomes.

Parental and Societal Attitudes

Finally, the broader social and cultural context cannot be ignored. In a largely monolingual society, languages are sometimes perceived as non-essential. Without strong parental support or visible social value attached to language learning, students may approach the subject with limited motivation. Research has shown that learner belief in the usefulness of the subject is a key predictor of sustained engagement (Dörnyei & Ushioda, 2011).

Conclusion

Learning a language is not a sprint — it’s a marathon with detours, plateaus, and the occasional uphill struggle. Despite what catchy slogans and language apps suggest, becoming proficient in a second language takes time, practice, and above all, meaningful exposure. While frameworks like the CEFR and FSI provide useful benchmarks, they must be interpreted through the lens of the learner’s context — including how the language is taught, how often it’s used, and how strongly it’s valued both inside and outside the classroom.

The good news? Every hour spent meaningfully engaged with a language — whether reading, listening, speaking, or thinking — builds momentum. And while reaching fluency might take longer than hoped, especially in classroom settings with limited input, the benefits far outweigh the effort. Multilingual learners outperform their monolingual peers in metalinguistic awareness, memory, cultural knowledge, and even career opportunities. The journey might be long, but it is unquestionably worth it.

Why some words just stick—and others vanish

Let’s face it: some words are annoyingly sticky, while others are as slippery as wet soap. Any teacher who’s spent five minutes in a language classroom knows this. You’ve probably wondered: why can learners remember chien, gato, or Haus, but not espérer, crecer, or vergessen? The answer lies in research—and lots of it.

In this post, I’m going to walk you through ten factors that influence how easy (or hard) a word is to learn, drawing on the science of second language acquisition and my own years of observing students learning French, Spanish, and German. More importantly, I’ll show how to make all of this practical, with clear implications for classroom practice.

1. Frequency: Words need airtime

Words that learners encounter often are learned more easily. That’s not just teacher instinct—it’s one of the most well-established findings in second language acquisition research. Nation (2001) and Ellis (2002) both showed that repeated, meaningful exposure strengthens memory traces and increases the likelihood of recall and use. In simple terms: if a word turns up a lot, students are more likely to notice it, understand it, remember it, and eventually use it.

In languages like French, Spanish and German, the most frequently used words are often highly irregular, functionally critical, and foundational for everyday communication. Think avoir, ser, sein—these are the glue that hold the sentence together.

The role of frequency is not just about how many times a word appears, but how it appears: in varied, engaging, and multimodal contexts. Encounters across different tasks and modalities—reading, listening, speaking, and writing—reinforce learning far more effectively than isolated repetition.

Implications for the classroom: Design your curriculum around high-frequency words using corpora-informed lists and real-life language samples. Build in multiple, spaced, and varied encounters. Don’t teach a word once and move on. Use narrow reading, retrieval practice, and oral recycling strategies to keep core vocabulary alive and active. Combine receptive and productive practice to ensure frequency supports fluency, not just recognition.

2. Concreteness: You can’t picture freedom

Concrete words—things you can see, touch, taste, or hear—are more memorable than abstract ones. Paivio’s Dual Coding Theory (1991) helps explain why: concrete words are encoded both verbally and visually in the brain. Learners can form mental images of chat, mesa, or Apfel, but struggle to visualise justice, libertad, or Ehre.

Concrete words also tend to be more context-rich and emotionally engaging in classroom activities. They often lend themselves to visual support, story-building, and physical enactment, all of which increase the chances of retention. Abstract words, by contrast, are more likely to be confused or forgotten without explicit strategies to reinforce their use.

Implications for the classroom: Front-load your curriculum with highly imageable, concrete vocabulary. Use realia, flashcards, mime, and classroom objects to bring these words to life. Pair new vocabulary with vivid visual or kinaesthetic input. Delay abstract nouns and idiomatic expressions until learners have a stronger foundation in the target language and are more confident inferring meaning from context.

3. Cognates: Use them, but use them wisely

Cognates—words that sound and mean the same in two languages—are great accelerators of learning. Research by Ringbom (2007) shows they’re picked up more quickly due to positive transfer from the first language. When learners already have a mental representation of the form and meaning, all they need to do is map it onto the target language, which reduces cognitive load.

However, cognates can also backfire. False friends—words that look similar but have different meanings—can create confusion and fossilised errors. For example, actuellement in French means “currently,” not “actually,” and embarazada in Spanish means “pregnant,” not “embarrassed.” Left unchecked, these errors can persist for years and may be particularly difficult to unlearn.

Implications for the classroom: Leverage true cognates early to build learner confidence and vocabulary quickly. Use them to scaffold understanding in reading and listening texts. At the same time, explicitly highlight false cognates using visual contrasts, translation tasks, or matching games. Encourage learners to keep personal lists of false friends and review them regularly. Cognates are powerful tools—but only when handled with precision.

4. Sound and Spelling: If it sounds weird, it sticks less

Phonological and orthographic simplicity support word learnability. Ellis and Schmidt (1997) found that unfamiliar or irregular sound–spelling correspondences create additional cognitive load and delay word recognition and recall. For example, the French word oiseau (bird) is tricky for learners because it includes silent letters and unexpected letter combinations. German compounds like Staubsauger (vacuum cleaner) are long and morphologically dense, while Spanish tends to be more phonemically transparent.

When learners cannot decode a word easily, it undermines both recognition and pronunciation, making them less likely to use it in speaking or writing. Learners may avoid unfamiliar forms altogether or mispronounce them in ways that interfere with communication and fluency.

Implications for the classroom: Choose beginner vocabulary that follows regular and predictable sound–spelling patterns. Use phonics training, particularly in French and German, to reinforce decoding skills. Model pronunciation clearly and frequently. Encourage learners to build up phonological awareness gradually by comparing similar words and practising minimal pairs. When introducing tricky spellings, link them to familiar sounds or rhymes.

5. Morphology: Patterns help memory

Morphologically related words—words that share a root—are easier to remember. Nation (2013) argues that building awareness of derivational and inflectional families allows learners to store and retrieve vocabulary more efficiently. A learner who recognises that hablar, hablo, and hablamos all share a root will retain them more easily. Likewise, in German, recognising the shared root in lesen, liest, las, and gelesen can enhance comprehension and production.

Morphological transparency also helps learners make educated guesses about unfamiliar words. If they know écrire means “to write,” they are better positioned to understand écrivain (writer) or réécrire (to rewrite). This not only expands vocabulary breadth but also deepens learners’ understanding of how the language system works.

Implications for the classroom: Highlight word families through colour-coding, word maps, and suffix trees. Group vocabulary by root, not just by topic. Use matching or sorting activities that focus on form–meaning relationships. Encourage learners to track prefixes, suffixes, and root patterns in reading texts. When introducing verbs, showcase full paradigms early so learners can spot consistencies and predict new forms.

6. Context: Words don’t live in isolation

Words embedded in meaningful, engaging contexts are more memorable than words taught in lists. Nagy et al. (1985) found that inferencing meaning from context can rival direct instruction in its effects. When learners encounter manger in a short story about a picnic or spielen in a dialogue about hobbies, they don’t just memorise the word—they absorb its usage, tone, and emotional weight.

Rich context creates multiple connections: lexical, grammatical, pragmatic, and cultural. These connections act as memory hooks, making recall easier and more intuitive. Additionally, contextualised vocabulary promotes deeper processing and gives learners the “why” and “how” behind word use, not just the “what.”

Implications for the classroom: Ditch decontextualised word lists in favour of stories, dialogues, and tasks that simulate real communication. Pre-teach vocabulary through short narratives, and revisit the same words in new settings. Use content-based instruction or theme-based units that provide extended exposure. Include guided noticing tasks where learners deduce word meaning from linguistic and situational clues.

7. Emotion and personal connection

Words tied to personal relevance or emotion tend to stick. Schwanenflugel et al. (1992) found that emotional salience increases depth of processing, improving recall. Learners don’t forget words that describe their passions, frustrations, or favourite activities. When learners choose words that matter to them—whether it’s chanson, canción, or Lied—the word becomes part of their identity, not just their vocabulary.

Emotion enhances memorability through affective engagement and increased attention. It also builds autonomy and motivation, which are critical for sustained vocabulary learning. Personal connections are the bridge between memory and meaningful use.

Implications for the classroom: Integrate student choice into vocabulary learning. Provide vocabulary banks related to hobbies, interests, or identity and let students select a portion of words they want to learn. Encourage self-curated vocabulary notebooks. Use creative writing, role plays, and projects that allow learners to personalise language. Ask learners to justify or rate words based on emotional resonance or usefulness in their own lives.

8. Word type: Not all parts of speech are born equal

Some grammatical categories are easier to acquire than others. Gentner (1982) showed that nouns are more easily learned than verbs or adjectives, because they’re more concrete and less syntactically complex. Nouns tend to map directly onto tangible referents, while verbs require learners to grapple with tense, aspect, and argument structure.

Adjectives, too, can present challenges—especially in languages with agreement systems like French or German. Meanwhile, function words such as prepositions and determiners, although frequent, are abstract and difficult to define, making them harder to acquire despite their ubiquity.

Implications for the classroom: Start with a curriculum rich in high-frequency concrete nouns. Delay instruction of abstract verbs, adjectives, and function words until learners have a solid foundation in basic grammar and vocabulary. When teaching verbs and adjectives, use sentence builders and role play to support their integration into spoken and written output. Use visual organisers that show part-of-speech relationships to help learners navigate categories.

9. Semantic transparency

Words with one clear meaning are easier to learn than polysemous words (words with multiple meanings). Cross (2009) noted that ambiguous vocabulary takes longer to process and recall. Learners encountering feuille (leaf/sheet), banco (bank/bench), or Schloss (lock/castle) need to hold multiple possible meanings in mind and rely heavily on context to decode correctly.

This can lead to confusion, misinterpretation, or overgeneralisation. Beginners are especially vulnerable, as they often lack the linguistic and contextual tools to resolve ambiguity efficiently. Semantic transparency therefore plays a critical role in initial vocabulary acquisition and instructional sequencing.

Implications for the classroom: Choose semantically clear, concrete words at the early stages of learning. Avoid overloading students with polysemous or idiomatic items until they have sufficient exposure to contextual cues. When introducing ambiguous words, provide multiple examples of usage and practice inferencing with support. Use pictures, definitions, and example-rich contexts to disambiguate and reinforce accurate meaning.

10. Collocations: Words that travel in packs

Words are often easier to learn when they’re taught as part of multi-word units. Schmitt and Carter (2004) showed that collocations and formulaic sequences aid recall and fluency by reducing cognitive processing time and enhancing automaticity. When learners internalise phrases like prendre un café, tener razón, or eine Entscheidung treffen, they bypass the need to construct each element separately.

Learning words in collocation also supports pragmatic competence—knowing not just what to say, but how native speakers typically say it. It strengthens grammatical intuition and speeds up processing in both comprehension and production.

Implications for the classroom: Teach vocabulary in chunks from the very beginning. Use sentence builders, dialogues, and substitution drills to embed target collocations. Create opportunities for learners to use formulaic language in real-time tasks like discussions or role play. When presenting new words, always give examples in typical phrase structures rather than as isolated items. Focus on high-frequency, contextually useful word combinations.

Final thoughts

So what does all of this mean for classroom practice? It means that how we choose and sequence vocabulary is far from arbitrary—it should be grounded in what we know about how words stick. Some words are more learnable than others, and knowing why can give us the edge we need to make vocabulary learning more efficient, more enjoyable, and more effective.

Start by focusing on high-frequency words. These form the backbone of basic communication and will give your learners the most mileage early on. Don’t just teach them once—make them pop up again and again, in reading, listening, speaking, and writing tasks.

Use concrete, imageable words wherever possible, especially in the early stages. They’re easier to visualise, easier to link to prior knowledge, and more memorable. Support them with pictures, mime, gestures, or real objects.

Cognates are fantastic for building confidence—just be careful with false friends. Teach them explicitly and contrast them with the true ones. Learners love to spot patterns between languages, and rightly so—it helps them build their internal lexicons faster.

Phonology and spelling matter more than we think. When words sound strange or look unpredictable, they’re harder to store. Early on, prioritise words that are easy to decode and pronounce, especially in languages with tricky sound–spelling rules like French or German.

Build morphological awareness early. Group verbs and nouns by families, and highlight roots and affixes that recur across multiple words. It’s a powerful way to stretch vocabulary and deepen memory.

Don’t teach words in isolation. Create rich, meaningful contexts through stories, dialogues, and real-world tasks. Words stick when they’re emotionally and semantically grounded.

And finally, let your learners choose some of the words they learn. Vocabulary tied to hobbies, emotions, or everyday life will always win the memory battle. Language is personal—make sure vocabulary learning is too.

Collocations	Phrases aid retrieval (Schmitt & Carter, 2004)	prendre un café / tener razón / Entscheidung treffen	Teach chunks, not just words

If there’s one thing I’ve learned in 30 years of teaching, it’s this: how we choose and teach vocabulary matters. A lot. Some words will be forgotten no matter what, but by focusing on what the research says about learnability, we can stack the odds in our learners’ favour

Teach the high-frequency. Prioritise the concrete. Exploit the cognates (carefully). Embed in context. Teach patterns. Honour personal interest. And above all—keep things memorable, meaningful, and motivating.

Because at the end of the day, the most learnable word is the one that actually gets used.

Introduction: When Everything Is Important, Nothing Is

One of the most common and dangerous assumptions in vocabulary teaching is that all words are equally important. This belief — often reinforced by thematic lists, textbook sequencing, or “fun” vocabulary — leads to wasted effort, cognitive overload, and, frankly, poor communicative payoff.

The truth is this: in real language, some words matter a great deal more than others. A handful of high-frequency words do the heavy lifting, while thousands of others live in the shadows of occasional use. This isn’t an opinion. It’s a statistical reality, first observed by linguist George Zipf (1935) and later confirmed across a wide range of languages and domains.

However, if we only focus on those top 1,000 words, we risk draining our lessons of personal relevance, cultural richness, and opportunities for self-expression. For example, words like le pingouin or la trottinette may be low frequency, but they often spark curiosity and provide hooks for meaningful communication. The art of good teaching is in finding the right balance — prioritising the high-frequency core, but leaving space for the occasional low-frequency gem that truly resonates with learners.

In this post, we’ll explore what Zipf’s Law is, why it matters, and how it should shape vocabulary teaching in instructed second language acquisition (ISLA). Along the way, we’ll also look at what this means for Modern Foreign Language (MFL) teaching in school settings — including both the opportunities and the potential pitfalls.

Please note that, although Zipf’s Law has been around for nearly a century and is one of the first things I was ever taught on my MA TEFL’s ‘L2 Acquisition Principles’ module back in 1997! It is funny how some people in the UK MFL circles treat it as some new breakthrough in L2 pedagogy… It isn’t. In the EFL world, language programming has been based on high-frequency word teaching for several decades!

What Is Zipf’s Law?

Zipf’s Law describes how word frequency is distributed in any natural language: the most common word occurs twice as often as the second most common, three times as often as the third, and so on. This creates a power-law distribution, where a tiny number of words account for the vast majority of all word occurrences in speech and writing.

For example, in English, the top 100 words cover about 50% of all written or spoken text, and the top 1,000 words account for roughly 80% of tokens in a standard corpus (Nation, 2001). The remaining words — tens of thousands of them — each appear rarely and carry diminishing returns for communication. The same holds true for French. According to the Lexique corpus and oral frequency studies (New et al., 2001), the top 150 words account for approximately 50% of everyday speech, and the top 1,000 cover around 85% of most texts. Beyond that, vocabulary frequency drops off steeply, with tens of thousands of words appearing only once in hundreds of thousands of words of input. This reinforces the principle that frequency-driven vocabulary selection is just as critical in French as it is in English.

In other words: if you’re teaching “la myrtille” (blueberry) or “le homard” (lobster) before your students can say “je veux”, “il y a”, or “je prends”, you’re teaching against the grain of how language actually works, according to current wisdom in the Applied Linguistics research community.

Why This Matters for ISL

In ISLA, where input and contact time are limited, learners cannot rely on incidental exposure to acquire the breadth and depth of vocabulary needed for real-world comprehension. This makes the principled selection of vocabulary absolutely essential.

Zipf’s Law reminds us that we shouldn’t treat all vocabulary as equal. Some words are exponentially more useful than others — not just for comprehension, but also for production, task success, and confidence building. Prioritising high-frequency vocabulary early on gives learners the best chance of gaining access to comprehensible input and generating meaningful output from the start.

Research shows that learners need knowledge of around 2,000 to 3,000 high-frequency word families to achieve 95% lexical coverage of typical texts — a threshold necessary for adequate comprehension (Laufer & Ravenhorst-Kalovski, 2010). However, to reach 98% coverage — the level associated with full reading fluency — learners would need up to 8,000–9,000 word families (Nation, 2006).

Implications for Vocabulary Teaching

1. Teach the most frequent words first

The top 1,000–2,000 words offer disproportionate access to real-life input. These are the words that learners need for basic survival communication and to begin noticing patterns in input. They allow learners to understand a wide range of texts and participate in simple conversations. Starting with these items gives learners a base of lexical material that can be quickly recycled, reused, and expanded upon.

According to Schmitt and Schmitt (2014), teaching the first 2,000 word families should be the top priority in any second language vocabulary programme, as these offer the highest utility for both receptive and productive language.

Table 1 – Words commonly taught in the food topic which are low-frequency

Word	Why It’s Problematic
la cerise	Taught in fruit lists but low in input frequency and rarely used communicatively.
le poireau	Included in Studio food vocab; infrequent in real-world communication and difficult to recycle.
la betterave	Appears in healthy eating contexts but is obscure, unmemorable, and low frequency.
l’ail	Taught in food vocab but rarely used productively by learners; low recall.
le foie	Found in meat sections; culturally specific, rarely used, and often off-putting to learners.
la confiture	Common in breakfast sets but mid-to-low frequency in real input and limited for communicative use.
le miel	Introduced in food units; rarely heard in oral corpora and not central to beginner tasks.
le canard	Included in meat lists in Studio 2, but low-frequency and not learner-relevant.
la dinde	Taught in food/meat sets; low frequency and culturally narrow in scope.
l’agneau	Found in meat vocabulary; extremely rare and often unknown even to learners in L1.
les champignons	Taught early but not high frequency and not often used by learners in speech or writing.

2. Prioritise frequency within thematic contexts

While frequency should guide word selection, thematic teaching can still play a valuable role in maintaining learner motivation and fostering meaningful communication. Themes like “food”, “daily routines”, or “school life” provide a coherent context for vocabulary, allowing learners to develop interconnected networks of meaning. They also support the development of topic-based conversations and help learners feel that they can talk about real-life experiences.

The compromise is to embed high-frequency vocabulary within thematic units, ensuring that learners are not wasting time on isolated or obscure items, while still benefiting from the motivational and organisational advantages of theme-based teaching. Research by Daller, Milton, and Treffers-Daller (2007) suggests that motivation and lexical relevance are strong predictors of vocabulary uptake, especially in school-based foreign language learning contexts.

For instance, would you always categorically not teach any of the words in Table 1 above, just because they are not frequent enough?

3. Emphasise multiword chunks and collocations

High-frequency words often combine into high-frequency phrases: I don’t know, Do you want to…?, There is/are. These chunks are essential for fluency and are processed faster than isolated words. They support both listening comprehension and fluent output. Teaching chunks helps learners acquire ready-made building blocks for communication and fosters grammatical awareness implicitly. Chunks also reflect the way language naturally occurs, reinforcing learner intuition and confidence.

Studies by Boers and Lindstromberg (2008) highlight the pedagogical value of formulaic sequences, showing that learners who are taught high-frequency collocations and chunks exhibit faster processing times and more fluent language production.

4. Engineer comprehensible input

Texts and listening materials can be crafted or selected to recycle high-frequency words intentionally. This repetition supports incidental learning and increases opportunities for retrieval and consolidation. Teachers can create texts that flood learners with targeted vocabulary while maintaining naturalness and interest. Rich input enables learners to notice how words behave in different contexts and contributes to the development of a robust mental lexicon.

Research by Webb and Nation (2017) shows that repeated exposure to vocabulary in meaningful contexts is one of the most effective ways to support retention and depth of processing.

5. Don’t overload beginners with rare words

Words like la myrtille (blueberry), la pastèque (watermelon), le homard (lobster), or la carotte râpée (grated carrot) can be fun but they appear rarely in input and are hard to retain. Introducing them too early results in poor long-term retention and delays learners’ ability to engage with authentic language. Schmitt and Schmitt (2014) argues L2 instruction should focus on the words that unlock the most language, both in terms of input and output. Lower-frequency words can be introduced gradually, once learners have developed a solid high-frequency base.

This aligns with findings by many other eminent researchers (e.g. Waring and Nation,1997; Laufer and Ravenhorst-Kalovski, G., 2010), who argue that introducing low-frequency vocabulary too early places an unnecessary burden on working memory and is often forgotten without extensive reinforcement.

6. Base word selection on corpus-informed frequency lists

Tools like the BNC/COCA corpus, the CEFR-based frequency bands, or the NCELP lists offer an empirically grounded way to prioritise vocabulary. These can guide syllabus design and resource selection far more reliably than textbook-driven intuition. Frequency lists allow for systematic coverage of core vocabulary and ensure learners are exposed to words that are genuinely useful. They also help teachers maintain consistency and transparency in their planning.

7. Use SRS for rarer vocabulary

Low-frequency words — the long tail — need intentional retrieval practice. Spaced repetition systems (SRS) can help keep these words alive once learners have built a strong core lexicon. These tools allow learners to control the human forgetting curve, revisit difficult items, and build long-term retention. For school settings, digital flashcards or quiz platforms can be used to integrate SRS into class time or homework routines.

As mentioned in several previous posts of mine, research by Bahrick (1984) and later Karpicke and Roediger (2008) provides strong evidence that spaced retrieval and repeated testing lead to superior long-term vocabulary retention compared to passive review.

An IMPORTANT Note of Caution: Motivation, Relevance, and the Long Tail

As useful as Zipf’s Law is, it should not be followed with blind dogmatism. A curriculum that teaches only the top 1,000 words may be efficient, but it can quickly become dry, demotivating, and disconnected from the learners’ lived experiences or interests. Not all high-frequency words are equally exciting to teenagers — and not all low-frequency words are useless. A Year 9 student may find quicksand more memorable than some, thing, or there.

In MFL, where student motivation is already fragile, it’s crucial to find a balance between utility and relevance. That means making room for high-interest, low-frequency words — particularly when they support personal expression, curiosity, or cultural engagement. The goal is not to ignore the long tail, but to introduce it strategically, in meaningful contexts, and after learners have built a functional core lexicon. In other words: start with the high-frequency core, but layer in personalised, memorable vocabulary to keep learners engaged.

As many of my readers would know, this is the approach we have taken on The Language Gym website and in the books, of course.

Summary Table: Zipf’s Law and ISLA Vocabulary Teaching

Zipfian Principle	Pedagogical Implication
A few words dominate real usage	Prioritise the top 1,000–2,000 words
Most words are rare	Avoid low-frequency vocabulary early
Language is chunked	Teach high-frequency phrases and collocations
Input matters more than intention	Use rich, repetitive, input-based tasks
Frequency predicts retention	Teach with frequency in mind, not themes alone
Motivation matters	Include personally meaningful vocabulary selectively
Rare words are harder to acquire	Recycle intentionally or use SRS for long-tail words

---

Conclusion: Frequency Isn’t Everything — But It’s a Great Place to Start

Zipf’s Law offers a valuable corrective to decades of inefficient vocabulary teaching. It reminds us that words are not equally useful and that real-world communicative value should trump textbook convenience or topic neatness. For ISLA, where time and input are limited, frequency is a powerful filter for what to teach first.

But frequency is not everything. Learner interest, identity, and curiosity also matter. Vocabulary instruction, then, is not just a matter of statistical prioritisation — it’s a matter of pedagogical tact: knowing when to stick to the core and when to deviate in order to sustain motivation and spark genuine engagement.

The best teachers will do both: build fluency through high-frequency input, while allowing for low-frequency magic when the moment is right.

Introduction

As I prepare a series of workshops for MFL teachers in Australia, I’ve taken the opportunity to delve deeply into some of the most recent and relevant research on vocabulary acquisition—specifically focusing on studies published over the last ten years. This review is not just academic: it’s been prompted by an increasing number of schools, teacher associations, and training providers asking me to share evidence-informed strategies for vocabulary instruction. The fact that so many are requesting input in this area speaks volumes about the growing awareness that vocabulary is not just one part of the curriculum—it is the foundation upon which comprehension, fluency, and spontaneous speech are built.

The findings presented below are not abstract or theoretical. They speak directly to the reality of MFL classrooms: mixed-ability learners, time constraints, and pressure to deliver measurable progress. What unites these ten insights is their practical value. They can be embedded in daily practice, whether we’re planning a Key Stage 3 scheme of work or reviewing how vocabulary is recycled and assessed at GCSE.

Most of the findings reinforce practices many experienced MFL teachers already use—structured input, chunking, sentence-level modelling. Others offer opportunities to tweak, challenge, or strengthen what we do. All are grounded in robust research and point toward the same goal: helping learners retain and use words more effectively, more confidently, and more independently.

1. Repetition Through Speaking and Listening Strengthens Memory

(Carter, 2017; Chien & Chen, 2020)

When vocabulary is encountered and reused through speaking and listening tasks, it is retained more effectively (50% better!) than vocabulary encountered only in written form. This is partly due to the way the brain encodes sound through the phonological loop—a system that favours oral and aural input for long-term memory formation.

In MFL classrooms, this has major implications. Learning vocabulary through listening activities (e.g. through circling, multiple-choice quizzes, ‘Listen and Draw, ‘Gapped translation’, ‘Faulty translation’) and speaking ones (paired speaking tasks, drills, speaking frames, and oral question-answer routines) don’t just build fluency—they deepen retention. Hearing and saying phrases like “je vais aller” repeatedly in context (e.g. during information-gap tasks or speed dating activities) anchors them in memory far more effectively than copying them into a book.

2. Timely Feedback on Word Use Makes a Difference

(Schmitt & McCarthy, 2019; Carrol, 2017)

Timely, specific feedback on vocabulary use—whether oral or written—can lead to a 20% increase in future accuracy. This is because feedback delivered close to the point of error helps learners notice and adjust their internal language models before misconceptions become entrenched.

In MFL lessons, this might involve live marking during extended writing, highlighting commonly misused words after a speaking assessment, or using peer correction with model answers. It also reinforces the importance of activities that make learner thinking visible—such as mini whiteboards or sentence-building tasks—so that misconceptions can be addressed immediately.

3. Digital Tools Can Help—If Used Consistently

(Godwin-Jones, 2017; Stockwell, 2020)

Digital platforms that use spaced repetition have been shown to improve vocabulary retention by up to 40%, especially when they are used regularly and linked to classroom learning. These tools support memory by prompting recall at increasingly spaced intervals, just as learners are about to forget.

For MFL departments, this suggests value in embedding digital vocabulary tools into weekly routines—not just recommending them for homework, but explicitly training pupils how to use them well. Creating class sets aligned with schemes of work or homework review quizzes on digital platforms can turn receptive vocabulary exposure into active recall practice. Make sure, however, that the exposure to the target vocabulary is as multimodal as possible (i.e. encompassing all four skills) as happens, for instance, on http://www.language-gym.com.

4. Motivation Significantly Boosts Vocabulary Retention

(Macaro et al., 2020; Dörnyei, 2019)

Motivated learners retain up to 50% more vocabulary than their less engaged peers. This is because motivation increases attention, effort, and willingness to review and reuse vocabulary over time. Crucially, it also increases the likelihood that learners will use words spontaneously.

In the MFL classroom, motivation can be nurtured through small but meaningful strategies: building in student choice, celebrating visible progress (e.g. class word count trackers) and linking vocabulary tasks to topics learners care about. For example, letting learners describe their own weekend plans rather than invented characters makes vocabulary personal, which in turn makes it stick. Engaging interactive vocabulary games involving mini whiteboard use and fun retrieval practice activities such as ‘Faster’, the ‘4,3,2 technique’ and digital games (e.g. the Language Gym’s ‘Boxing game’ and the ‘Vocab Trainer’) will help too, of course.

5. Receptive Vocabulary Develops 1.5 Times Faster than Productive Vocabulary

(Gyllstad, 2020; Nation, 2020)

It is entirely natural for learners to recognise and understand vocabulary long before they are able to use it themselves. Receptive vocabulary develops 1.5 times faster than productive vocabulary because it places less demand on syntax, spelling, pronunciation, and retrieval.

This finding validates the use of input-focused tasks—narrow reading, listening with targeted vocabulary, and teacher-led modelling—before expecting learners to write or speak. It also supports the use of structured scaffolds (sentence builders, gapped texts, writing frames) that help bridge the gap from passive recognition to active production over time.

6. Learners Need to Encounter a Word 15–20 Times Before It Sticks

(Webb, 2016; Elgort, 2018)

A few encounters with a new word are not enough. Learners typically need between 15 and 20 meaningful, spaced exposures before a word moves into long-term memory. These encounters must be varied and multimodal—reading, hearing, saying, and writing the word in different contexts.

This underscores the importance of recycling vocabulary not just across lessons, but across units and terms. A word like “parce que” should appear not just in Year 7 but in every subsequent year. Activities such as sentence transformation, low-stakes quizzes, retrieval grids, and structured translation can ensure repeated exposure over time.

7. Vocabulary in Context Is Remembered Better

(Hulstijn, 2018; Coxhead, 2018)

Words are learnt more effectively (30% better retention!) when they are taught in meaningful context rather than in isolation. Context helps learners understand usage, grammar, and connotation. It also provides semantic and syntactic cues that aid retention.

In practice, this means presenting vocabulary within phrases and full sentences—not just as English–French pairs. Model sentences, listening texts, and reading activities that repeat key phrases provide both form and function. Sentence builders, in particular, allow learners to see how vocabulary fits grammatically within familiar structures.

8. Collocations and Chunks Reduce Errors and Build Fluency

(Laufer & Goldstein, 2020; Schmitt, 2019)

Learners who are taught vocabulary in the form of collocations (e.g. “avoir faim”, “faire une promenade”) or multi-word chunks (e.g. “il y a”, “je suis en train de”) make fewer errors (30% accuracy improvement!) and produce more fluent speech. These combinations are stored and retrieved as whole units, reducing cognitive load during speaking and writing.

For MFL teachers, this supports focusing less on isolated nouns and more on useful chunks that include verbs, prepositions, and time expressions. Teaching “je vais + infinitive” or “normalement je + present tense” as building blocks helps learners speak more fluently and write more accurately.

9. Explicit Instruction Improves Accuracy by Around 25%

(Gass, 2019; Macaro, 2021)

When vocabulary is taught explicitly—rather than left to be inferred through exposure—learners show a 25% improvement in accuracy. This includes clear explanations of meaning, form, grammar, pronunciation, and common collocations.

In the MFL classroom, this reinforces the value of modelling pronunciation, pointing out tricky gender rules, and explicitly teaching the difference between similar words. Rather than relying solely on discovery learning, it encourages deliberate instruction through worked examples and teacher-led practice.

10. Vocabulary Size Drives Comprehension

(Meara, 2017; Nation, 2020)

Learners need to know approximately 2,000 to 3,000 word families to understand 85% of general texts. This is a threshold for independent comprehension. Below it, learners are likely to become discouraged due to too many unknowns.

For MFL teachers, this highlights the importance of focusing on high-frequency vocabulary across all key stages. It’s tempting to focus on topic-specific words, but the bulk of our time should be spent on the most common verbs, connectors, and adjectives. Structured vocabulary progression models and high-frequency word trackers can help ensure systematic exposure and development.

11. Summary of the findings

Conclusions

As I prepare to share these findings with colleagues during my workshops in Australia, I’m reminded that vocabulary learning is rarely immediate. It is a slow-building process that depends on repetition, motivation, context, and structure. Teaching vocabulary effectively means helping learners meet the same word multiple times, in meaningful ways, and with the support they need to process and retrieve it.

These ten findings, taken together, point us toward a vocabulary curriculum that is cumulative, focused, and deeply rooted in how memory works. They validate many of the techniques MFL teachers already use—retrieval practice, chunk teaching, sentence-level work—and offer encouragement that these approaches are not only intuitive, but research-backed.

Introduction

In the realm of second language acquisition, not all grammar structures are created equal—some present intricate challenges for learners, while others are picked up with relative ease. Knowing what makes a particular structure tough is crucial for effective grammar teaching. When curriculum designers and classroom teachers recognize these underlying complexities, they can tailor instructional strategies to prevent common errors and sequence grammar content in a logical, progressive way that fits learners’ needs. This awareness not only helps in error prevention but also streamlines the learning process by anchoring new information to a solid foundation, ultimately empowering learners to build their language skills with confidence and clarity.

1. Crosslinguistic Interference

Crosslinguistic interference refers to the influence of a learner’s first language (L1) on acquiring a second language (L2). When grammatical rules in the L2 differ significantly from those in the L1, learners might inadvertently transfer structures from their native language, which can result in errors or even avoidance of unfamiliar forms. This challenge has been extensively discussed by Odlin (1989) and Lado (1957), who argue that structural mismatches are a primary source of difficulty in L2 grammar acquisition.

For example, in French, the use of the subjunctive mood (e.g., Il faut que tu viennes) has no direct counterpart in English and can be confusing. In Spanish, object pronouns precede the verb (Lo vi), which is contrary to English word order. German employs case markings and flexible word order (e.g., Ich gebe dem Mann das Buch), while Italian permits clitic pronouns attached to infinitives (e.g., voglio vederlo), which may seem opaque to English speakers.

Solutions: Teachers should use contrastive analysis and metalinguistic explanations to highlight differences between the L1 and L2 (Jarvis & Pavlenko, 2008). Translation tasks can reveal subtle distinctions, while bilingual glossaries with grammar notes can serve as ongoing reference tools. Corrective feedback focused on typical L1-based errors helps learners refine their usage. Teachers can also incorporate task-based learning activities that require students to actively compare and contrast grammatical structures between languages. Peer feedback sessions and guided discovery tasks enable learners to identify L1 interference patterns themselves, thereby deepening their metalinguistic awareness.

2.Low Saliency

Some grammatical elements are hard for learners to notice because they are either phonetically reduced or carry little semantic weight. These include structural words , gender markers, auxiliary verbs, and clitics. Schmidt (1990) emphasized the importance of noticing in second language acquisition, arguing that forms not salient in the input are often not acquired.

In French, articles such as le and la are often unstressed. Spanish pronouns like me and se can be hard to catch in rapid speech. German articles (der, die, das) indicate gender and case but are easily overlooked. In Italian, contractions such as al (from a + il) may be indistinct in conversation.

Solutions: Increase saliency through visual cues, color coding, and emphasis in speech (input enhancement). Slowed-down recordings, subtitled media, and grammar highlighting tools can help learners perceive and internalize these subtle forms (Schmidt, 1990). When working on a text, make sure you include one or more activities which elicit a focus on less salient items (e.g. Gapped dictations, Sentence puzzles, Tick or cross, Tangled translations)

3. Irregularity

Irregular grammatical patterns defy the logical systems learners rely on to deduce rules. This inconsistency often necessitates rote memorization and increases the likelihood of errors. Ellis (2006) notes that irregular forms resist rule generalization and demand increased memorization, making them particularly taxing for learners.

Examples include French verbs like avoir, être, and aller, which do not follow regular conjugation patterns. In Spanish, preterite forms such as tuve (from tener) and hice (from hacer) deviate significantly. German strong verbs and Italian verbs like essere and avere also exhibit irregularities across tenses.

In my experience, a motivated beginner learner might start to reliably use aller in the present tense, in context, after approximately 10 to 20 hours of practice spread over several weeks. This has to be factored in in your curriculum planning.

Solutions: Provide frequent, contextual exposure to irregular forms and distributed retrieval practice. Use songs, rhymes, and interactive games to boost engagement. Encourage learners to teach one another and use mnemonics to make irregular patterns more memorable (Ellis, 2006). Use online verb trainers, like the one on http://www.language-gym.com.

4. Challenging Processability
Grammatical structures that require a sequence of processing steps are harder for learners to produce accurately. These include multi-step verb constructions, reflexive forms, and subordinate clauses. According to Pienemann (1998), such structures exceed a learner’s current processing capacity until they have acquired the necessary grammatical procedures.
For instance, French compound tenses with reflexive verbs (Je me suis levé), Spanish compound tenses (He comido), German subordinate clause word order (weil er das Buch gelesen hat), and Italian modal constructions (Devo mangiarlo) are cognitively demanding.

Solutions: Scaffold learning by isolating each component of the structure. Visual aids, flowcharts, and sentence diagrams help learners conceptualize the construction. Role-playing and contextual practice solidify these forms in memory (Pienemann, 1998). Modeling, scaffolded peer interactions, and encouraging learners to create their own mind maps or flowcharts to break down complex sentences are effective. Additionally, reflective self-monitoring techniques can help students track their progress in mastering these multi-step constructions. The key thing is not to teach a complex structure when your students are not ready for, just because it is in the textbook or in the schemes of learning. You will just set up your students for failure !

5. High Element Interactivity
Some grammatical forms depend on the interaction of multiple features such as gender, number, case, and verb agreement. Learners must coordinate these elements, which increases the cognitive load. VanPatten (2007) suggests that learners struggle when multiple grammatical features require simultaneous attention, especially if they have not yet become automatized.

French past participle agreement (Elles sont parties), German adjective endings (dem kleinen Kind), Spanish reflexive sentences (Se lo di), and Italian relative clauses (Il libro che ho letto) all involve multi-layered agreement.

Solutions: Use color-coded sentence templates and scaffolded sentence-building activities. Group tasks and collaborative construction exercises reinforce understanding through guided repetition and peer feedback (VanPatten, 2007). Complement these strategies with technology-based interactive exercises that allow students to manipulate sentence components on digital platforms (e.g. The Language Gym Grammar workouts). Stage ‘Spot and correct the error’ activities quite frequently. When providing translation practice, ensure that the sentences containing such structures do not contain unfamiliar vocabulary in order to lessen the cognitive load.

6. Intralinguistic Interference
This occurs when learners confuse similar-looking or similar-sounding forms within the L2. Such interference arises not from the L1, but from the internal complexity of the target language. Lado (1957) and Wierzbicka (1988) highlight how internal grammatical ambiguity can confuse learners and hinder acquisition.

In French, verb endings like parle, parles, and parlent sound similar but differ in meaning. Spanish verbs can have similar endings (e.g., hablamos, hablan). German pronouns like sie can mean “she,” “they,” or “you” (formal). Italian prepositions like a and da are easily confused.

Solutions: Mitigate the issue by not introducing too many similar sounding words (e.g. full verb paradigms) simultaneously. Use minimal pair drills, cloze exercises, and spelling-focused tasks to distinguish similar forms. Mnemonics and dictation can further aid in consolidating these differences (Wierzbicka, 1988). Structured pair work and small-group discussions centered on error analysis can also help learners develop clearer distinctions.

7. Low Frequency of Exposure and Use
When learners rarely encounter certain grammatical forms, acquisition is delayed or incomplete. These forms may be limited to specific registers, such as literature or formal speech. Ellis & Larsen-Freeman (2006) emphasize that frequency of input is critical in usage-based models of acquisition.

Some French negatives (e.g. ni…ni…), the Spanish future perfect tense, the German subjunctive mood (Konjunktiv II), and the Italian passato remoto are examples of such low-frequency items.

Solutions: If you believe that such structures are must-learns, make sure you create frequent practice opportunities both receptively and productively. Integrate these forms into retrieval practice routines, classroom narratives, themed projects, and authentic texts as often as possible. Use spaced repetition flashcards and target listening/reading to boost exposure and retention (Ellis & Larsen-Freeman, 2006).

8. Optionality

Grammatical optionality allows for variability, which can lead to inconsistent usage. Learners may omit or misapply optional elements if their functional purpose is unclear. Sorace (2011) notes that optional forms are particularly difficult to master because their use often involves an interface between syntax and pragmatics.

In Spanish, subject pronouns are often dropped (e.g., Yo hablo → Hablo). In French, informal negation drops ne (e.g., Je sais pas). German and Italian also exhibit optional structures depending on formality and context.

Solutions: Explicitly teach when and why forms are optional. Contrast obligatory and optional uses through corpus-informed examples. Drills and feedback that focus on stylistic and pragmatic appropriateness are key (Sorace, 2011).

9. Functional/Semantic Unreliability

Grammatical forms that serve multiple functions across contexts can confuse learners. They may struggle to assign correct meanings without sufficient contextual cues. Wierzbicka (1988) argues that such multifunctional elements obscure clear mappings between form and meaning, hindering acquisition.

French en, Spanish se, German doch, and Italian ci each fulfill several roles, varying by sentence context and syntactic placement.

Solutions: Demonstrate each function with clear contextual examples. Use semantic maps to visualize relationships between meanings. Gradually expand the range of usage scenarios to build reliable application (Wierzbicka, 1988).

Conclusion

In light of the diverse challenges posed by grammar structures—from crosslinguistic interference to functional unreliability—it’s clear that both classroom teaching and curriculum design need to be flexible and responsive. For classroom teachers, this means mixing things up with targeted, varied strategies that directly address each structure’s challenges. Whether it’s using contrastive analysis, scaffolded exercises, or interactive, real-world practice, teachers can help students overcome common hurdles while making grammar feel more accessible and less intimidating.

For curriculum designers, the key takeaway is to build a program that gradually ramps up the complexity of grammar content. This means sequencing lessons in a way that respects the natural cognitive challenges learners face, offering regular and spaced practice, and ensuring that even those tricky, irregular forms get plenty of contextual exposure. By designing a curriculum that is both research-informed and flexible enough to adapt to students’ needs, educators can create a learning environment where error prevention and gradual skill development go hand in hand.

Overall, when both teachers and curriculum designers keep these implications in mind, they can build a more effective, learner-centered approach to second language acquisition—one that makes the journey through the complex world of grammar not only manageable but also engaging and enjoyable.

Introduction

Alongside listening, speaking is the skill that scares learners the most—and rightly so. Unlike writing, where you can take your time and carefully polish your words, speaking happens on the fly. There’s no backspace key. No time to hesitate. Everything has to come together in real-time: the message you want to convey, the grammar to wrap it in, the vocabulary to fill it out, and the sounds to articulate it. And if you’re learning a second language, the load becomes even heavier. Each sub-process—planning, retrieving, encoding, monitoring—takes up your mental energy like separate strings pulling in different directions

In this article, I focus primarily on teaching speaking to lower-intermediate learners, corresponding roughly to the B1 level of the CEFR. At this level, learners can communicate in everyday situations, handle short social exchanges, and describe experiences or events in simple terms, but often struggle with fluidity, accuracy, and vocabulary depth. In the UK, many GCSE students—particularly in their final year—fall somewhere between A2 and low B1, depending on exposure, instruction quality, and individual aptitude. While GCSE specifications may claim alignment with B1 outcomes, most learners operate with far more limited productive fluency, especially in spontaneous speech.

For learners operating at lower-intermediate or intermediate level, this makes speaking a cognitively exhausting endeavour. Planning what to say in a foreign language under time pressure—while also keeping track of how you’re being understood—is no easy feat at this level of proficiency where vocabulary is limited and grammar and pronunciation are far for being proceduralised thereby requiring a lot of simultaneous juggling of challenging cognitive operations.

One of the most influential frameworks for understanding how speaking unfolds is Levelt’s (1989) model of speech production. Originally designed to describe L1 speaking processes, the model has been widely adopted and adapted within L2 acquisition research. It outlines four key stages: conceptualisation, formulation, articulation, and monitoring. In L2 contexts, scholars such as Kormos (2006) have extended the model to include the impact of limited attentional resources, slower lexical retrieval, and interference from the learner’s first language. These modifications are crucial, as they highlight that L2 speech is not simply “slower L1 speech,” but involves qualitatively different challenges, particularly in the coordination of sub-processes under pressure.

This article outlines the cognitive sub-processes involved in the act of speaking, referring to Levelt’s original model and L2-specific extensions. Each stage will be examined in detail, with a focus on the time it unfolds, its cognitive demands, and how it affects L2 speakers. Finally, we explore how a process-oriented approach to listening and speaking instruction—beginning with lexical chunks and culminating in fluency training—can mitigate these challenges.

How the speaking process unfolds in the brain

The flow chart below visually represents the key sub-processes involved in speaking, starting with conceptualisation, where the speaker decides what to say. It then moves to formulation, where vocabulary and sentence structure are selected. Phonological encoding follows, as the speaker prepares the sounds for articulation, including aspects like stress and intonation. The articulation step represents the physical production of speech. Finally, monitoring occurs, where the speaker checks for errors and makes corrections if needed. Each of these stages presents unique challenges for second language learners, such as difficulties in vocabulary recall, grammar application, pronunciation, and maintaining speech flow while self-monitoring.

Let’s zoom in

Conceptualisation: From Intention to Preverbal Message

According to Levelt’s (1989) influential speech production model, the first stage in speaking is conceptualisation—the process of formulating an intention and generating a ‘preverbal message’. This is where the speaker decides what they want to say based on their communicative goals, the context, and their interlocutor.

This stage is largely non-linguistic and draws heavily on working memory and attention (Baddeley, 2000). In L2 users, this phase is often slowed by limited automaticity in accessing ideas or by difficulties in filtering what is relevant for the context. Lower-intermediate learners in particular struggle with task schemata—knowing what content is expected in specific interactions (Bygate, 2001). The typical time window for this initial conceptual preparation is 200–400 milliseconds (Indefrey & Levelt, 2004).

Formulation: Lexical Selection and Grammatical Encoding

Sticking with our French weekend example, the learner now attempts to say something like “J’ai regardé un film avec mes amis.” To do this, they must retrieve verbs in the passé composé, choose the correct auxiliary, recall agreement rules, and access the noun and modifiers. For lower-intermediate learners, this is where it often falls apart. They might know the verb “regarder” but hesitate on the auxiliary—avoir or être? They might reach for “copains” instead of “amis,” or get stuck trying to recall the correct article.

Once the preverbal message is ready, the speaker moves into formulation, where the message is encoded linguistically. This involves:

• Lexical selection: choosing appropriate content and function words

• Grammatical encoding: applying morphological and syntactic rules to create well-formed utterances.

This phase is cognitively taxing, particularly for L2 learners. Vocabulary retrieval in an L2 is significantly slower (Segalowitz, 2010), and grammatical encoding is often interrupted by underdeveloped procedural knowledge (DeKeyser, 2007). Moreover, lexical access in L2 speakers is more susceptible to interference from the L1, which can cause lexical or structural errors.

The time estimates for lexical selection are roughly 150–250 milliseconds per word, depending on familiarity and fluency (Levelt et al., 1999; Indefrey & Levelt, 2004). Sentence-level formulation can take longer, especially in less automatized learners. In this very narrow time window the language learner needs to retrieve the correct vocabulary, apply any morphological rule and then sequence the words in the correct order. Unsuprisingly, many students who have not been taught vocabulary and grammar orally fail at this stage in the process. Imagine a year 8 or 9 students having to retrieve the words required to describe what they and their friends did last weekend whilst simultaneously having to apply the rules of the perfect tense of verbs requiring the auxiliary Etre in 250 milliseconds! No wonder they usually answer using prefabricated chunks !

Phonological Encoding and Articulation

Assuming the formulation phase is successful, the learner must now articulate: “J’ai regardé un film avec mes amis.” But here too, things get tricky. Mispronunciation of “regardé,” deaccentuation of “mes amis,” or poor rhythm can impair intelligibility. A frequent issue is the liaison in “mes amis”—if not made, the learner’s speech sounds choppy or unclear. Or the learner might struggle with the uvular [ʁ] in “regardé,” substituting a harder English-like ‘r’ that interferes with intelligibility. These phonological glitches are common even when vocabulary and syntax are intact.

In this stage, the speaker organises the phonological form of the utterance. This includes retrieving the correct pronunciation, applying prosodic features (intonation, rhythm), and preparing motor plans for articulation.

Fluent L1 speakers can initiate articulation within 600–750 milliseconds of conceptualisation (Meyer, 2000), but L2 learners may hesitate, pause, or mispronounce words due to weak phonological encoding. This is especially evident in learners with low exposure to authentic spoken input or limited phonological memory (Service, 1992).

Lower-intermediate learners often struggle with:

• Phoneme discrimination and recall
• Prosody (especially in stress-timed languages like English)
• Applying correct intonation in real-time

These issues compound when learners are under pressure to speak fluently, increasing their cognitive load and sometimes causing breakdowns in communication.

Monitoring: Self-Regulation and Repair

The final sub-process is monitoring, where the speaker evaluates their output for accuracy and appropriateness. Levelt (1989) conceptualised this as an internal speech comprehension loop: the speaker hears their own output and compares it with their intention.

Even if the learner says “J’ai regardé un film avec mes amis,” they might instantly second-guess themselves. Was it regardé or regardais? Should they have said copains instead of amis? This internal checking process can lead to unnecessary corrections or hesitations—”J’ai… euh… j’ai regardé… non, j’ai vu un film…” These repairs slow down speech and can reduce fluency, especially if the learner is preoccupied with form over communication. Encouraging learners to tolerate minor slips and correct after speaking can reduce this form-focused overload.

In L2 learners, the monitoring system is often overloaded. Lower-intermediate speakers may lack the fluency to detect errors in real-time, or they may be too focused on accuracy, causing frequent self-repairs, hesitations, and a loss of fluency (Kormos, 2006). The balance between fluency and accuracy in self-monitoring is often skewed towards caution, leading to reduced confidence and processing speed.

Cognitive Bottlenecks for L2 Speakers

For lower-intermediate to intermediate learners, the real-time nature of speaking creates several cognitive bottlenecks:
• Slow lexical retrieval: due to lack of automaticity and limited exposure
• Grammatical processing overload: conscious rule-application slows down encoding
• Phonological instability: weak sound representations affect fluency and intelligibility
• Overactive monitoring: learners focus too much on error-avoidance rather than message delivery
As a result, these learners often rely on formulaic expressions, pauses, fillers, and simplified syntax to manage cognitive load.

Implications for a Process-Based Approach: the FIVE PILLARS of speaking instruction

Understanding the cognitive complexity of speaking has major implications for classroom instruction—particularly if we truly want to go beyond ‘speaking practice’ and actually develop real-time speech competence. Rather than treating speaking as a single monolithic skill, we need to see it as a layered process. Each sub-skill—conceptualising, retrieving lexis, applying grammar, encoding phonology, articulating and monitoring—must be nurtured in its own right, and gradually automatized through carefully scaffolded instruction.

One key implication is this: if we’re serious about helping our learners speak fluently, we must abandon the traditional ‘accuracy-first’ model that floods learners with grammar rules, then expects them to string words together on the fly. It simply doesn’t work—not in real-time conditions where cognitive load is already through the roof. Instead, learners need repeated, structured exposure to lexis and grammar in context, followed by masses of retrieval and recycling across the modes. This includes input processing, controlled output, guided fluency training and carefully spaced retrieval. Each phase of this cycle must map clearly onto a specific stage of the speech production model. And, most importantly, it must feel safe and doable for the learner.

In my own practice, I’ve found that modelling language through high-frequency lexical chunks, sentence builders and communicative routines creates a reliable scaffold. When learners can plug content into predictable structures, they’re free to focus their cognitive energy on message construction and pronunciation. That’s when real fluency starts to emerge—not when they’re mentally conjugating verbs while trying to hold a conversation.

Monitoring, too, deserves special attention. Learners at this level often monitor too much—pausing, correcting, second-guessing. We need to re-train them to delay monitoring until after their message is out. Recording, re-listening, summarising, peer editing—all of these build confidence and reduce the urge to self-correct mid-sentence.

Finally, let’s not forget the bigger picture: speaking proficiency is deeply rooted in listening. You can’t produce what you haven’t processed. That’s why I always recommend beginning with listening-as-modelling—intensive, scaffolded, chunk-based listening input that feeds into structured oral output. Only when input is rich, patterned, and digestible can output become fluent.

In what follows, I outline five pillars of process-based instruction that address the major bottlenecks identified above. Rather than viewing speaking as a single monolithic skill, instruction should address each sub-process through targeted practice and gradual automatization.

1. Begin with Lexical Chunks

Let’s start with the basics. If we want to reduce the cognitive load associated with formulation, we must give learners language they can draw on quickly and easily. This is where teaching lexical chunks—pre-assembled word sequences—makes all the difference. Following Wray (2002) and Nation (2013), instruction should start with frequent, high-utility lexical chunks that serve communicative functions. These bypass the need to assemble utterances from scratch and give learners the scaffolding they need to speak more fluently from the start.

In my own approach, sentence builders and oral fluency routines built around these chunks are core. When learners can retrieve and manipulate these ready-made building blocks, they’re no longer paralysed by the need to “find the right word” or mentally conjugate verbs mid-sentence. The end result? Increased fluency, confidence, and willingness to engage.

Following Wray (2002) and Nation (2013), instruction should start with frequent, functional lexical chunks. These bypass the formulation phase by providing ready-made building blocks. In my approach, for instance, sentence builders, retrieval practice and oral fluency tasks built around these chunks are used in order to reduce planning time and boost fluency.

2. Support Grammar Proceduralisation

Grammar doesn’t just need to be learned—it needs to be automatised. Far too often, learners are expected to remember isolated rules and apply them in real time, under pressure. Unsurprisingly, they struggle. What we need instead is a gradual shift from declarative to procedural knowledge—what DeKeyser (2007) and Ellis (2002) have long advocated.

In practical terms, this means designing tasks where learners are repeatedly exposed to key structures in varied, meaningful contexts. One set of activities in this process is repetitive oral drills, or “chunking aloud,” where students repeatedly practise grammatical structures in varied contexts to reinforce their automatic recall. This may be followed by oral retrieval practice tasks where students tests one another on the target chunks of language (e.g. Oral ping-pong, Battleship, Snaked and Ladders or No snakes no ladders). This is complemented by controlled speaking practice, where learners engage in structured dialogues or speaking tasks that focus on a specific grammar point, providing the opportunity to use the form in context. Additionally, sentence expansion and transformation exercises encourage learners to manipulate sentences by changing components or structures, which helps them internalise grammar rules through active use. Communicative activities, such as information gaps and role-plays, further promote the use of grammar in real-life contexts, enhancing both fluency and accuracy. Feedback, both immediate and delayed, plays a key role in identifying errors and reinforcing correct grammatical usage, ensuring that learners are able to reflect on their mistakes and adjust their use of grammar in future speaking tasks. These activities work together to support grammar proceduralization, allowing learners to move from conscious rule application to the automatic use of grammatical structures in spontaneous communication.

In the above tasks the target grammar structures are made ‘task essential’, i.e. necessary for the completion of a task. For instance, you may design a Mind-reading and Sentence Stealer game followed by an ‘Oral Ping-Pong’ and a ‘No snake no ladder task’, and by a short dialogue (with L1 prompts) to be translated orally where the French verb Faire in the present features in every single sentence. This may be followed by a Spot the difference task where Partner 1 and 2 have to describe their respective pictures still using Faire in the present. Finally, you could stage a game of Faster recycling the same verb. You would hope, at the end of this sequence to have reached a degree of proceduralization of the target verb in the present, wouldn’t you?

In essence, grammar instruction should aim at proceduralisation—not just rule explanation. This can be achieved through repeated use in familiar contexts (Ellis, 2002), pattern drills, and structured input tasks where grammar is embedded in meaningful communication.

3. Enhance Phonological Awareness

Phonological encoding is the silent saboteur of L2 fluency. Learners might know what they want to say—but if they can’t retrieve the sounds or stress patterns of the words, their message stalls. This is especially true for learners from syllable-timed L1 backgrounds trying to speak stress-timed languages like English.

So what’s the fix? Learners need systematic training in phonological decoding and encoding. Activities like minimal pair discrimination, prosody shadowing, and rhythm tapping are not ‘nice extras’—they are essential. Listening-as-modelling, one of the key pillars of my instructional framework, plays a central role here. By repeatedly hearing and mimicking well-modelled input, learners internalise the rhythm and stress patterns that underpin fluent delivery. Chunking aloud and other reading-aloud techniques, too, of course, play a key role.

4. Train Strategic Monitoring

Learners often monitor their speech too much—and too early. The result? Frequent pauses, self-corrections, and disrupted communication. What they need is training in strategic monitoring: learning when and how to correct themselves in a way that supports fluency rather than undermines it.

One way to do this is by using recording and playback tasks, where learners speak first and evaluate later. Another is to apply fluency-then-accuracy sequences, where learners produce language freely before revisiting their output for improvement. As Kormos (2006) suggests, shifting monitoring to a post-production phase can free up working memory and reduce performance anxiety. Of course, not every learner will need this level of scaffolding, but it can be transformative for those at risk of fossilising or losing confidence.

Do we have the time to do the above with every student and class? Maybe not, maybe only with your exam classes, but it is well worth the time you are prepared to invest in these activities.

5. Prioritise Fluency Training

Fluency doesn’t just happen. It must be explicitly taught, nurtured, and rehearsed systematically. And no, fluency isn’t just about speaking fast—it’s about the seamless coordination of all sub-processes under time pressure. This is what makes it so cognitively demanding and what makes explicit fluency training such a pedagogical priority.

Drawing on the work of Nation (1989, 2013), we must treat fluency as a skill in its own right, with structured and repeated opportunities for learners to speak under progressively less scaffolded, more time-sensitive conditions. Time-limited speaking tasks, repeated performance activities (such as the 4-3-2 technique), and familiar-task recycling allow learners to gradually speed up the retrieval and formulation process.

In my own framework, fluency is the final stage of a cycle that begins with highly scaffolded input (listening as modelling), builds through structured output (with sentence builders and oral frames), and culminates in ‘pushed output’. Here, learners are encouraged to retrieve and manipulate language chunks quickly and spontaneously in a controlled environment. Activities such as ‘Messengers’, the ‘4,3,2 technique’, ‘Market place’, ‘Faster’ and ‘Fast and Furious’ are great ways to work on oral fluency. We gradually increase the demands—not just on speed, but also on accuracy and complexity—as learners’ confidence grows.

When learners know the lexis, the grammar is proceduralised, the pronunciation is modelled, and the task is clear, they can focus on flow. That is the true goal of fluency training—not speed for its own sake, but smooth, confident, and intelligible communication.

Conclusion

Speaking is not a single act but a series of fast-paced, overlapping cognitive operations. Each sub-process—conceptualisation, formulation, phonological encoding, articulation, and monitoring—presents unique challenges for L2 learners, particularly at the lower-intermediate and intermediate levels. By recognising these challenges and targeting instruction accordingly, we can build learners’ capacity to speak fluently, accurately, and confidently.

Whwther you embrace EPI or not, a process-based approach, beginning with chunks and leading toward fluent, spontaneous production, provides a roadmap for overcoming cognitive bottlenecks and enabling real communicative competence.

Introduction

Assessment is the area of language teaching where theory and classroom practice often collide. We all want to assess fairly, meaningfully, and efficiently—but tight timetables, systemic pressures, and time constraints frequently pull us in other directions. For many of us, assessment becomes a stressful afterthought—rushed, inconsistent, and often disconnected from the learning we so carefully plan.

This article offers a set of ten key principles to guide classroom-based assessment in a way that both supports learning and aligns with research. The aim is not to provide a rigid checklist, but a set of flexible reminders: principles we can strive for when designing, adapting, or reflecting on assessment practices.

Importantly, these principles are aspirational. Many teachers, including myself, often lack the time and resources to implement them all fully. But knowing what “better” looks like can help us make informed trade-offs, tweak existing practices, and build assessment routines that actually support learning.

If I’ve learned anything about language testing, it’s thanks to the late Professor Cyril Weir, whose clarity of thought and deep understanding of assessment shaped my thinking when I studied under him over 30 years ago.

1. Validity – Test What You Actually Taught

What it means

Validity means your assessment measures what it claims to. If you say you’re testing listening skills, but the real challenge lies in understanding unfamiliar vocabulary, cultural references, or decoding poor-quality audio, the task is not valid.

In language classrooms, invalid assessments happen all the time:

• A listening task in the textbook asks learners to infer whether a character is happy or sad—but students struggle because the audio includes many unfamiliar structures (e.g., passé composé forms not yet taught
• A writing task asks students to “describe a past holiday” before they’ve learned the passé composé with être or irregular verbs like faire. Most learners will either write in the present or produce error-ridden texts.
• You mark “grammar accuracy” but test includes structures never modelled in class.

According to Messick (1989), a valid assessment must measure the intended construct without interference from unrelated skills or knowledge. In L2 contexts, Fulcher and Davidson (2007) also warn against “construct-irrelevant variance”—where results are skewed by factors that shouldn’t matter (e.g., background knowledge, decoding ability, handwriting).

Possible solution

Make sure assessment tasks reflect what learners have actually practised. Recycle taught language, limit new vocabulary, and avoid assessing grammar that hasn’t been modelled repeatedly. Use familiar task formats to reduce cognitive load. When teaching using sentence builders or substitution tables (as in the EPI approach), assess those same patterns—not “creative writing” from scratch.

2. Reliability – Be Consistent and Fair

What it means

Reliability refers to how consistent assessment results are across time, teachers, or contexts. If the same piece of work would earn different marks from different teachers—or from you on different days—your system isn’t reliable.

This is a well-documented problem. Research by Alderson et al. (2000) and Barkaoui (2007) shows that in language assessments, scoring variation is high, especially in writing and speaking.

In practice, we see this in:

• Teachers applying mark schemes inconsistently in GCSE-style writing tasks.
• Oral assessments where confidence or accent sways scores more than structure use.
• Comments like “Nice effort” for one learner and “Needs more complexity” for another—despite similar output.

Inconsistency undermines trust in assessment. Learners can’t improve if they don’t know what counts as “good” and why.

Possible solution

Use transparent success criteria (e.g., “Includes at least three time phrases,” “Connects ideas using et, mais, parce que”) instead of vague rubrics. Moderate samples with colleagues, or cross-check with exemplar responses (e.g., AQA/Edexcel sample responses for the GCSE). Use whole-class marking codes to streamline and reduce subjectivity.

3. Authenticity – Make Tasks Feel Real

What it means

Authentic tasks mirror real-life language use. They feel purposeful, relevant, and engaging. When assessments are too artificial or contrived, learners don’t see the point—and often perform poorly because the situation feels unfamiliar.

Examples of poor authenticity:

• Writing a postcard from a theme park—when learners have never seen or written a postcard.
• Listening to a contrived conversation between “two cousins visiting the Eiffel Tower” in exaggerated accents and stilted dialogue.
• Reading an article about “Why children should avoid too much screen time” in formal register—impossible to relate to for Year 8 students.

Gilmore (2007) highlights that authentic tasks increase motivation and better reflect communicative competence. When learners can imagine themselves using the language, their engagement and performance improve.

Possible solution

Use purpose-driven tasks that reflect real communication: voice messages, roleplays for booking or complaining, WhatsApp-style exchanges, social media posts. Avoid tasks that only serve the test. Adapt textbook prompts if needed (e.g., turn “write about your school” into “write a review for an exchange partner”).

4. Washback – Make Assessment Drive Good Learning

What it means

Washback refers to the impact assessment has on teaching and learning. Hughes (2003) and Bailey (1996) show that learners focus on what they think will be tested. So if your assessments reward memorisation and neatness over fluency and risk-taking, that’s what students will prioritise.

Negative washback examples:

• Marking only grammatical accuracy in writing—but encouraging creative use of chunks in lessons.
• Testing only reading and writing—so students disengage from speaking tasks.
• Giving “fill-the-gap” tests every term—so learners memorise phrases rather than learn how to manipulate language.

Possible solution

Design assessments that reflect and reward the habits you value: recall, improvisation, clarity, range. If you’re using retrieval practice in lessons, assess it. If fluency-building is a goal, include spontaneous speaking. Use assessment as a continuation of teaching, not a switch in focus.

5. Transparency – Be Clear About What Counts

What it means

Transparency means that learners understand what they’re being assessed on, and what success looks like. Without this clarity, they can’t prepare effectively or act on feedback.

Research by Sadler (1989) and Black & Wiliam (1998) shows that learner understanding of criteria is essential for progress.

Lack of transparency often looks like:

• Ambiguous phrases in rubrics: “some complex language,” “generally accurate,” “shows understanding.”
• No explanation of how tasks are graded—learners focus only on the number.
• Tasks set without clear models, so students are shooting in the dark.

Possible solution

Before assessments, show worked examples at different levels and ask students to annotate what works and why. Use visual rubrics or traffic-light criteria (“must include a time phrase, an opinion, a justified reason”). After assessments, give feedback aligned to the criteria—not just a number.

6. Practicality – Keep It Manageable

What it means

Practicality is about whether your assessment system is sustainable. If you’re drowning in marking, or learners are overwhelmed, something’s got to give.

Poor practicality examples:

• Termly assessments that take weeks to mark but give little insight.
• Tasks that require long periods to explain or complete—leaving little teaching time.
• A speaking test where only one pair speaks while the rest of the class waits.

Research by Brindley (2001) and Green (2014) confirms that assessments must fit operationally into teaching. Otherwise, they’ll be done infrequently—or poorly.

Possible solution

Assess little and often. Use mini-tasks (e.g., one-minute oral summaries, sentence corrections, 40-word writing bursts). Use retrieval-based assessment (e.g., do-now tasks, hinge questions) for a snapshot of learning. Share the load with peer- or self-assessment.

Also, avoid high-stakes “mega-tests.” Use a portfolio of smaller, focused assessments over time. That’s how real learning is best captured.

7. Inclusivity – Remove Unnecessary Barriers

What it means

Inclusivity means all learners—regardless of SEN, EAL background, or cognitive processing style—can access and succeed in assessments if they know the material.

In practice, exclusion often comes from:

• Listening once at full speed with no visual support.
• Writing prompts that require imaginative thinking but don’t scaffold basic sentence formation.
• Tasks that rely on background knowledge learners may not have.

Research by Kormos & Smith (2012) and Mitchell (2014) stresses that inclusive assessment isn’t about lowering expectations—it’s about designing assessments that test the language, not processing speed or inferencing.

Possible solution

• Slow down audio or allow two listens.
• Use images or brief context to support listening/reading.
• Provide writing scaffolds (sentence starters, vocabulary boxes).
• Offer tiered task options (e.g., basic/extended) to allow learners to challenge themselves.

8. Formative Usefulness – Make Assessment Feed Learning

What it means

Formative assessment is assessment for learning, not just of learning. If the feedback you give never gets used, it’s wasted effort. One common piftall of feedback on assessment is that the students are not actively engaged in it.

Sadler (1989) and Wiliam (2011) show that feedback only works when learners are trained to understand and respond to it.

Common classroom fails:

• Red-pen marking with no time to respond.
• “You’re working at a 6” comments—without next steps.
• Feedback that’s generic (“use more detail”) or unclear.

Possible solution

Build in DIRT time (Dedicated Improvement and Reflection Time) in the feedback-handling phase of the assessment process with a very narrow focus (focus on 2 or 3 key issues only). Ask students to act on feedback immediately:

• “Fix these 3 sentences.”
• “Add a second reason to this opinion.”
• “Re-record your oral answer including a time phrase.”

Also, teach students how to interpret and use feedback. Otherwise, we’re just commenting into the void.

9. Constructive Alignment – Match Teaching and Testing

What it means

Constructive alignment means your assessments reflect how and what you’ve taught. If students prepare for tasks one way, and the test demands another, that’s not fair.

Examples of misalignment:

• Teaching sentence builders, then removing them completely in writing assessments.
• Practising oral fluency, but testing only reading comprehension.
• Focusing on vocabulary sets, then testing unseen grammar.

Biggs (2003) emphasises that aligned assessment helps learners transfer classroom knowledge into successful performance.

Possible solution

Assess the language routines learners have been taught: sentence frames, structures, collocations. If you’ve used retrieval activities and repetition in class, design your tests accordingly.

Include familiar scaffolds in assessments and gradually remove them as learners grow in confidence—not all at once.

10. Balanced Assessment – Don’t Let One Skill Dominate

What it means

Assessment should reflect the full skillset of language learning—not just writing or grammar.

In many English MFL classrooms, speaking and listening are neglected in favour of writing. This creates a distorted view of progress.

Examples:

• Only written work is formally assessed each term.
• Speaking is practised but never assessed.
• Listening is sidelined because “they find it too hard.”

As noted by Macaro (2003) and Turnbull & Arnett (2002), unbalanced assessment demotivates students and provides an incomplete picture of what they can do.

Possible solution

Track which skills you assess. Aim for at least one task per skill each half-term, even informally. Record speaking via Flip, use live listening tasks, and mark comprehension through gist or detail tasks.

Summary Table: Ten Key Principles

Principle	What it means (in plain English)
Validity	Test what you taught—don’t sneak in surprises
Reliability	Mark consistently and fairly, not on gut instinct
Authenticity	Use tasks that feel real, not made-up or schooly
Washback	Make sure tests encourage the habits you want
Transparency	Tell students what counts and what to expect
Practicality	Don’t overcomplicate—make it doable for all
Inclusivity	Give everyone a fair shot at showing what they know
Formative Usefulness	Make sure feedback leads to change, not just a tick
Constructive Alignment	Match what you test to how you’ve taught it
Balanced Assessment	Assess all four skills—don’t let writing rule the roost

Conclusion

Assessment, when done right, drives learning, improves motivation, and gives you an accurate picture of what your students can do. Done wrong, it frustrates, confuses, and demoralises.

These ten principles don’t require perfect conditions. Just better thinking, smarter choices, and small tweaks over time. Even adjusting one of them in your next assessment can make a meaningful difference.

We owe it to our learners to make assessment not just something that happens to them—but something that happens for them.

Introduction

In this article, I aim to provide practical, research-informed guidance on how written corrective feedback (WCF) in second language (L2) classrooms can be implemented more effectively and meaningfully—particularly under real-world teaching constraints.

This is a topic I’ve been personally invested in for over two decades. More than 20 years ago, I conducted my PhD research on the role of metacognitive strategies in error correction and the impact of self-monitoring on L2 writing.

My review of the specialised literature during the first year of my study made it all too clear to me that WCF is a far more complex issue than it appears on the surface. It is much more than simply marking errors, it must empower learners to become active, intentional, self-monitoring agents. Easier said than done!, you may think to yourself as you read this. Can’t blame you. Yet, the success of WCF is all about student intentionality. 

My PhD study also taught me a very hard lesson: doing WCF well requires a lot of time, the one commodity busy teachers in secondary schools around the world are very poor in! It also requires training that many teachers may not be able to access.

Given these practical realities, one cannot expect that language educators implement every ideal practice suggested by research!  Hence, the guidelines below are intended as a roadmap for gradual improvement rather than as a strict checklist or a criticism of current practice. 

Here are twelve common shortcomings of WCF practice, many of which I have been guilty of myself. 

11 common pitfalls evidenced by research into WCF

1. Reduced Learner Intentionality

When learners receive a barrage of corrections without clear guidance on which errors are most significant, they tend to become passive recipients of feedback. Swain (1995) argues that for effective error correction, learners must actively notice the gap between their interlanguage and the target language. Intentional engagement—where students compare their output with the correct form—builds metacognitive skills and reinforces self-correction. Ellis (2006) confirms that intentional self-correction promotes deeper processing and helps prevent fossilisation (Ferris, 2018).

Research by Lalande, Ferris, and Conti (2004) demonstrates that explicit instruction in self-monitoring strategies significantly improves learners’ error awareness and independence. Multiple classroom studies (e.g., Hyland & Hyland, 2006) have reported that students often feel overwhelmed by unstructured corrections, reducing their willingness to engage in self-initiated revision.

2. Insufficient Promotion of Self-Monitoring Strategies

Feedback that merely supplies the correct answer without prompting reflective comparison limits the development of metacognitive skills. Swain (1995) emphasizes that self-monitoring is critical; learners must be encouraged to actively compare their output with target forms. Studies by Vandergrift (2007) and Lalande, Ferris, and Conti (2004) indicate that learners trained in self-monitoring strategies become better at detecting and addressing recurring errors independently.

Empirical classroom research (Hyland & Hyland, 2006) documents that many teachers continue to provide corrections without engaging students in the reflective process. This omission prevents the development of independent editing skills, underscoring the need for explicit self-monitoring prompts in corrective feedback.

3. Overcorrection Leading to Cognitive Overload

Correcting every minor error can overwhelm learners’ limited working memory. Research consistently shows that correcting too many errors at once can lead to cognitive overload and reduced learning gains (Miller, 1965; Baddeley, 2003). Learners, especially those at lower proficiency levels, often struggle to process an excessive amount of feedback simultaneously. Bitchener (2008) and Ferris (2018) argue that focusing on high-priority or recurring errors—such as those that impede communication or reflect underlying gaps in knowledge—is more beneficial than marking every minor slip. Ellis (2006) supports this by advocating for focused feedback, which has been shown to result in greater long-term accuracy than unfocused correction. In short, quality over quantity is essential: teachers must strategically choose which errors to address in order to support deeper processing and reduce learner frustration.

Hyland and Hyland (2006) found that many teachers tend to mark nearly every error without filtering for significance. This unselective approach, documented in studies such as Bitchener (2008), increases cognitive demands and hinders the internalisation of corrections.

4. Differentiating Error Sources: Treating Errors Based on Their Origin

Errors in L2 writing often stem from different underlying issues. Some mistakes occur due to a lack of correct declarative knowledge—for instance, when a learner has not fully internalised an explicit grammar rule (Ellis, 2006). Other errors arise from insufficient procedural knowledge, where the learner knows the rule in theory but cannot consistently apply it automatically under real-time conditions (Swain, 1995; Norris & Ortega, 2000). Research indicates that these error types require different remedial approaches: explicit instruction and explanation are most effective for declarative knowledge gaps, while extensive practice and recycling promote the proceduralisation of rules. This differentiation is crucial; by tailoring feedback to the source of the error, teachers can provide more targeted and effective corrective strategies, as supported by Lalande, Ferris, and Conti (2004).

5. Lack of Clarity and Intelligibility

Ambiguous correction symbols or overly technical language in feedback can leave students confused about what is wrong and why. Ferris (2018) notes that clear, accessible feedback is essential for helping learners understand the nature of their errors, while Lee (2008) found that when corrections are explained in straightforward terms, students are more likely to grasp the intended meaning and apply the changes successfully.

Research by Hyland and Hyland (2006) consistently shows that many teachers use unclear or inconsistent symbols and comments, which undermines the corrective process and reduces the likelihood that learners will internalise the correct forms.

6. Delayed Feedback

When corrections are provided long after the writing task, the link between the error and its correction can weaken considerably. Long (2015) emphasizes that timely feedback is critical so that learners can immediately rehearse the correct forms while the context is still fresh in memory. Bitchener and Knipe (2008) support this view by demonstrating that prompt feedback is significantly more effective for error correction than delayed responses.

Classroom studies (Hyland & Hyland, 2006) indicate that many teachers delay feedback due to workload constraints or scheduling issues, thereby diminishing the impact of corrective information.

7. Inconsistency in Correction Methods

Using varied correction styles within or across texts can confuse students about which errors to address. Lyster and Ranta (1997) recommend that consistent correction techniques help establish stable error patterns, making it easier for learners to recognise and correct recurring mistakes. Inconsistent feedback dilutes the corrective message and leaves students uncertain about the relative importance of different errors.

Research by Bitchener (2008) documents that many teachers employ multiple correction systems simultaneously, and classroom observations (Hyland & Hyland, 2006) indicate that such inconsistency is a common issue that hinders students’ ability to develop a systematic approach to self-correction.

8. Missed Opportunities for Reprocessing and Revision

Without structured revision tasks or follow-up activities, students do not have sufficient opportunities to reprocess and internalise corrective feedback. Ferris (2018) and Swain (1995) note that learning from corrective feedback is not an instantaneous “aha” moment but a gradual process that benefits from deliberate re-engagement with the material. Follow-up revision tasks—such as re-writing exercises or peer review sessions—allow students to revisit corrections and strengthen the connection between error and resolution.

Studies by Lee (2008) consistently find that many teachers neglect to incorporate systematic revision activities after providing feedback, limiting the potential for long-term improvement.

9. Failure to Tailor Feedback to Individual Needs

Uniform feedback that does not account for differences in proficiency or individual learning strategies is less effective. Ellis (2006) has shown that customised feedback—addressed to a learner’s specific error patterns—supports better self-regulated learning and targeted improvement. Tailored feedback ensures that students receive the most relevant information for their own language development, thereby supporting more effective error correction.

Surveys and interviews by Norris and Ortega (2000) reveal that many teachers still adopt a one-size-fits-all approach, ignoring individual differences. This common shortcoming is linked to lower overall improvement rates among diverse learners.

10. Neglecting the Prevention of Fossilisation

When feedback is not clear, timely, or consistently managed, persistent errors can become fossilised in the learner’s interlanguage. Selinker’s (1972) seminal work, along with subsequent studies (Norris & Ortega, 2000), demonstrates that without strategic and ongoing corrective feedback, errors tend to become entrenched and resistant to change. Fossilised errors hinder long-term language development and are particularly difficult to eradicate once established.

Multiple studies (Ferris, 2018; Swain, 1995) document that many teachers fail to provide the continuous, focused feedback necessary to prevent fossilisation, underscoring the need for systematic, sustained error correction strategies.

11. Overemphasis on Remediation Instead of Prevention

A common pitfall in L2 writing instruction is focusing too much on remedial correction—reacting to errors after they occur—instead of preventing errors through careful instructional design and curriculum planning. While remedial feedback is necessary, a heavy reliance on it can result in reactive teaching that fails to address the root causes of errors. Research by VanPatten (2004) and Ellis (2006) suggests that integrating prevention strategies—such as designing scaffolded tasks, providing ample practice with target forms, and ensuring consistent recycling of language elements—can significantly reduce the overall error incidence. Norris and Ortega (2000) have shown that a curriculum focused on prevention leads to fewer errors and a smoother learning process. By shifting the focus from remediation to prevention, teachers create a learning environment where correct language forms are reinforced before errors become ingrained, thereby reducing the need for later correction and supporting long-term language development.

Implications for L2 pedagogy: I.M.P.A.C.T.E.D.

I.M.P.A.C.T.E.D. (see figure 1 below) is an acronym I have come up with which encapsules the main recommendations by researchers. 

Figure 2 – the IMPACTED framework for WCF

Informed feedback must respond to the learner’s needs and the specific context of the task. Research underscores the importance of tailoring feedback to learner proficiency and developmental readiness (Ellis, 2006; Ferris, 2018). Generic correction is rarely as effective as feedback based on diagnostic insight into the learner’s interlanguage and common error patterns (Lalande, Ferris & Conti, 2004).

Manageable feedback recognises the reality of teacher workload and the cognitive limits of learners. Overloading either party compromises learning. Miller’s (1965) classic findings on working memory capacity (7 ± 2 items) and Baddeley’s (2003) work on cognitive load stress the need for focus. Bitchener (2008) also highlights that teachers must be selective, correcting only what is most useful for long-term development.

Planned feedback aligns with long-term instructional goals rather than being merely reactive. VanPatten (2004) and Swain (1995) stress the need for integrating feedback within structured learning cycles. When feedback is anticipated and followed up by recycling and revision tasks, learners process it more deeply (Ferris, 2018).

Accessible feedback should be clear and learnable. Studies by Lee (2008) and Hyland & Hyland (2006) demonstrate that learners benefit most from feedback that uses student-friendly language and models corrections clearly. Ambiguity reduces the effectiveness of even well-intended feedback.

Constant feedback must be part of a continuous loop. Research supports the idea that revision and reprocessing are essential for internalisation (Swain, 1995; Ferris, 2018). Lalande, Ferris & Conti (2004) found that sustained engagement with feedback over time enhances self-monitoring and long-term gains.

Timely feedback helps prevent fossilisation of errors (Long, 2015; Bitchener & Knipe, 2008). When feedback is delivered while the task is still cognitively present, learners are more likely to reflect and revise meaningfully. Delayed correction often loses its pedagogical power.

Evidence-based feedback is grounded in a substantial body of SLA research. Focused feedback (Ellis, 2006), metalinguistic correction (Lyster & Ranta, 1997), and self-monitoring routines (Lalande, Ferris & Conti, 2004) have all been shown to support learner development. Using research-backed strategies ensures that feedback efforts are not wasted.

Deeply processed feedback demands active engagement. Wray (2002), Schmidt (1990), and Swain (1995) argue that noticing and reflection are prerequisites for acquisition. Simply reading corrections is not enough—learners must cognitively work through them, revise, and apply corrections in new contexts for lasting learning to occur.

Conclusion

Effective L2 written corrective feedback must do more than simply correct errors; it must foster intentional engagement that transforms feedback into an active learning process. When learners actively notice discrepancies between their writing and the target language, they build the metacognitive skills necessary for self-monitoring and independent improvement. Clear, timely, and prioritised feedback—combined with structured revision tasks—reduces cognitive overload and helps ensure that corrections are gradually internalised, preventing error fossilisation (Ferris, 2018; Swain, 1995).

It is also important to recognise that teachers face significant time constraints and heavy workloads. Research by Lalande, Ferris, and Conti (2004) underscores that while promoting self-monitoring and strategic feedback is highly beneficial, not every ideal practice can be implemented in every classroom. Teachers should not feel guilty or as if they are being criticised for not doing everything perfectly—there is only so much that can be accomplished given practical realities. Instead, these guidelines offer a roadmap for gradual, intentional improvement in feedback practices, including an emphasis on preventing errors through proactive instructional design.

In essence, intentional engagement in the feedback process is the foundation of long-term success. As students learn to understand and work through their mistakes with clear, structured, and manageable feedback, they develop greater autonomy and become more effective communicators. This holistic approach not only improves written proficiency but also contributes to a sustainable, self-regulated language learning process.
