Introduction
The debate over whether grammar or fluency should take precedence in second language acquisition (SLA) is long-standing. While grammatical accuracy is crucial for clarity and precision in communication, fluency—the ability to communicate ideas smoothly and naturally—arguably plays a more significant role in real-world language use.
Given the limited instructional time available for Modern Foreign Language (MFL) teaching—often only one or two hours per week—educators must make strategic choices about which aspects of language learning to prioritize. I will never forget my mentor and PhD supervisor, Oxford Uni Professor Macaro, saying to me once: ‘When you only see students once or twice a week, what do you want to teach them: how grammar works or how to listen and speak? The latter, of course!’. Researchers by and large, agree, suggesting that prioritizing oral fluency enhances motivation, aligns with students’ wants, lacks, and necessities, and fosters greater long-term retention. Furthermore, recent changes to the UK GCSE MFL curriculum allow students to achieve high grades with good fluency, even if they do not excel in grammatical accuracy. This, of course, does not entail not teaching grammar. Grammar can have an important role in supporting and expanding the development of fluency.
Additionally, research highlights that students from lower socio-economic backgrounds and those with poor literacy skills struggle significantly with grammar acquisition. DeKeyser (2005) argues that teaching grammar to such students constitutes a form of social injustice, as traditional grammar-focused methods disadvantage those without strong foundational literacy skills. Given this, a fluency-first approach may be a more equitable and effective strategy for ensuring all students can achieve communicative competence.
This article explores research-based arguments favoring fluency over grammar in language education and highlights best practices for achieving balanced language proficiency.
The Role of Fluency in Communicative Competence
Fluency is central to communicative competence, a concept introduced by Canale and Swain (1980), which defines effective language use as the ability to convey meaning efficiently and appropriately in real-life contexts. According to Nation (2007), fluency encompasses speed, automaticity, and ease of expression, all of which facilitate meaningful interactions. Research suggests that focusing too heavily on grammatical correctness can hinder fluency by causing learners to hesitate and overanalyze their speech, disrupting the natural flow of conversation (DeKeyser, 2018).
Studies on Second Language (L2) Communication Strategies have shown that learners who prioritize fluency are more likely to develop functional communication skills. For example, Ortega (2019) found that L2 learners who engaged in spontaneous speech activities without excessive grammatical correction demonstrated greater long-term retention and confidence in their speaking abilities. Given the time constraints of MFL instruction, it is imperative to focus on what will best prepare learners for real-world communication rather than perfecting grammatical accuracy at the cost of communicative competence.
The updated UK GCSE MFL curriculum supports this emphasis on fluency. The new framework prioritizes spontaneous conversation and communicative effectiveness, meaning that students who develop strong speaking and listening skills can achieve high grades even if their grammatical accuracy is not perfect. This further underscores the importance of prioritizing fluency over rigid grammatical structures.
Fluency Enhances Motivation and Aligns with Learner Needs
One of the major challenges in language learning is maintaining student motivation. Research by Horwitz, Horwitz, and Cope (1986) on Foreign Language Anxiety found that learners who feel pressured to produce grammatically perfect speech often develop communication apprehension, leading to reluctance in speaking. Conversely, a focus on fluency—allowing for minor grammatical mistakes—reduces anxiety and fosters a more positive learning environment (Dörnyei, 2009).
Dörnyei’s L2 Motivational Self System (2009) highlights that motivation is strongest when students see immediate, practical benefits from language learning. Learners are more likely to persist in their studies when they feel they are making progress in using the language rather than merely learning about its structure. With one or two hours per week, teachers must prioritize approaches that keep learners engaged and willing to participate actively in the learning process.
Furthermore, Needs Analysis Theory (Richards, 2001) suggests that language instruction should be aligned with students’ wants, lacks, and necessities. In many educational settings, learners express a greater desire for speaking and listening skills rather than a deep understanding of grammatical rules. Prioritizing fluency ensures that language learning remains relevant to their practical needs and enhances their perception of progress, which is crucial for sustained motivation.
Fluency Improves Long-Term Retention and Processing
Cognitive research suggests that fluency-focused approaches enhance automaticity, which is essential for long-term language retention. The Declarative-Procedural Model (Ullman, 2016) explains that grammatical rules are first learned explicitly but must become proceduralized through practice to be used effectively in real-time communication. Studies indicate that excessive emphasis on grammar instruction without fluency practice leads to a lack of automaticity, making spontaneous communication difficult (VanPatten, 2015).
Swain’s Output Hypothesis (1995) supports this perspective, arguing that learners must engage in meaningful, communicative output to internalize grammatical structures naturally. This is evident in immersion-based learning, where learners who prioritize conversation and interaction achieve higher fluency and natural grammatical acquisition over time compared to those who focus on rule memorization (Lyster & Sato, 2013).
A strong emphasis on grammar instruction may result in an instance of ‘social injustice’
Robert DeKeyser, one of the STRONGEST advocates of explicit grammar instruction, in his 2005 paper What Makes Learning Second-Language Grammar Difficult? A Review of Issues, explores the cognitive and socio-educational factors that impact L2 grammar acquisition. He argues that explicit grammar instruction—where students consciously learn and apply grammatical rules—is more accessible to learners with strong first-language literacy and well-developed metalinguistic awareness. However, for students from lower socio-economic backgrounds who may have weaker L1 literacy skills, this approach presents significant challenges. These learners often lack the academic language skills, working memory capacity, and formal education background that facilitate grammar rule processing, making them more reliant on implicit learning mechanisms.
DeKeyser suggests that traditional grammar-focused instruction can be an instance of social injustice when applied universally, as it places already disadvantaged learners at a further disadvantage by emphasizing methods that do not align with their cognitive and educational profiles. He advocates for more communicative, immersive, and fluency-based approaches for these students, which allow them to develop grammatical competence naturally through usage rather than through rule memorization. In this view, an overemphasis on explicit grammar instruction risks reinforcing educational inequalities rather than bridging the gap in language acquisition opportunities.
Conclusion
I love grammar. It suits the way I learn. But I am a highly-motivated and academically strong learner with a very inquisitive nature. I have a compulsive need to know how everything works. And, as many other individuals passionate about language learning, I seek as many opportunities for practising any newly-learnt grammar structures and vocabulary as possible, using any resources available to me. I am sure many other language educators feel and do the same.
However, given the limited time allocated to MFL instruction, teachers must make a strategic choice about what is most beneficial for student engagement and long-term progress. Research consistently supports the prioritization of fluency over explicit grammar instruction, as fluency fosters motivation, confidence, and communicative competence—all of which align with students’ wants, lacks, and necessities.
Furthermore, the recent changes to the UK GCSE MFL curriculum reinforce this perspective, as students can achieve high grades through strong fluency and communicative skills, even if they do not excel in grammatical accuracy. This policy shift supports a more realistic, communicative approach to language learning, emphasizing practical usage over rigid grammatical correctness.
Additionally, research highlights that students from lower socio-economic backgrounds and those with poor literacy skills struggle significantly with grammar acquisition. DeKeyser (2005) argues that teaching grammar to such students constitutes a form of social injustice, as it disadvantages those without strong foundational literacy skills. Given this, a fluency-first approach is not only more effective but also a more equitable strategy to ensure all students have the opportunity to achieve communicative competence.
With only one or two hours per week, language learning should focus on practical communication skills that provide immediate, tangible benefits for students. By aligning instruction with real-world communication needs, educators can ensure that students stay motivated, engaged, and better prepared to use the language in meaningful ways.
The failure of the NCELP initiative, which was mainly a grammar-centred approach, has taught us that students are not cognitive nor affectively aroused by an excessive focus on structural knowledge. As language teachers, whose duty is to put our students’ interests and weel-being first, we need to treasure that lesson.
