Introduction

Starting out as a Modern Foreign Languages teacher is exciting — but it can also feel overwhelming. Research in second language acquisition (SLA) and classroom pedagogy consistently highlights a number of traps that early-career teachers are especially prone to. I know this from experience: as a trainee in Hull back in 1992, I fell into many of these very pitfalls. Later, as a PGCE mentor, I saw novice teachers repeat them time and again.

This is hardly surprising. Research shows unequivocally that the way we teach is strongly shaped by our own experiences as language learners, as well as by the textbooks and materials we use in our schools. Habits and assumptions are inherited as much as they are chosen.

Of course, many of these pitfalls aren’t unique to beginners — even experienced colleagues slip into them occasionally. But novices often feel their impact more acutely, since they are juggling the simultaneous demands of behaviour management, heavy workload, and the pressure to “do it all.”

What follows are twelve of the most common and serious mistakes new MFL teachers make, along with reflections on why they matter — and how they can be avoided.

1. Teaching Too Much Grammar Too Soon

In the early years, many teachers feel they must “cover everything quickly.” This often leads to introducing multiple tenses or whole verb tables before learners have automatised the basics. Research shows that novice teachers often adopt a coverage model because they equate thoroughness with effectiveness (Borg, 2006; Farrell, 2012). SLA research (VanPatten, 1996, 2003; DeKeyser, 2005) shows that learners need sustained, meaningful practice with core structures before new ones can stick.

How textbooks contribute: While most modern textbooks no longer follow the old “one tense per unit” pattern, they often still present full paradigms or new structures in large chunks. Without careful pacing, teachers can end up introducing too much too soon.

2. Focusing on Accuracy Over Communication

Novices often correct every error out of fear that mistakes will fossilise. This “error-avoidance mindset” is well documented in teacher cognition studies (Borg, 2006; Copland, Garton & Burns, 2014). Yet Swain (1985, 1995) and Long (1996) show that negotiation of meaning and communicative risk-taking drive acquisition more than constant form-policing.

How textbooks contribute: Many textbook tasks are accuracy-driven (gap-fills, matching, drills) with fewer opportunities for authentic message-focused talk, which reinforces an “accuracy first” mindset.

3. Vocabulary Selection Without Sufficient Recycling

New teachers often follow the unit-by-unit pace of the book, which leads to one-off exposure to new words rather than long-term recycling (Borg, 2015; Newton, 2001). While recent reforms have improved textbooks by embedding frequency-based lists, research (Nation, 2001; Ebbinghaus, 1885) stresses that repeated encounters are essential for retention.

How textbooks contribute: Word lists are often thematically organised, and recycling across units is limited. Unless teachers deliberately revisit high-frequency items, words can disappear once a topic ends.

4. Making Lessons Too Dense and Hard to Process

Early-career teachers often “overteach” by cramming explanations or designing tasks with too many steps. This behaviour has been linked to the apprenticeship of observation effect — teachers reproduce the dense, teacher-fronted lessons they experienced themselves (Lortie, 1975; Borg, 2006). SLA research (Mayer, 2009; VanPatten, 2015) confirms that learners learn more when input is broken into smaller steps and scaffolded.

How textbooks contribute: Explanations are often presented as full-page tables or lengthy model texts, which can tempt teachers into overwhelming students with too much at once.

5. Limited Input and Reading Opportunities (receptive skills)

When it comes to the L2 input given to the students novices often prioritise the textbook’s comprehension activites, grammar drills and worksheets because they feel safer and more controllable than open-ended input tasks. Teacher education research shows that early-career teachers lean on form-focused, tightly structured activities to maintain classroom control (Farrell, 2009; Tsui, 2003). Yet acquisition depends on sustained exposure (Krashen, 1985; Lightbown & Spada, 2013).

How textbooks contribute: Reading and listening passages are typically short, exam-style texts written to practise specific vocabulary, rather than rich, extended input. This leaves little room for immersion.

6. Task Design That Stops at Controlled Practice (productive skills)

Novices often stop lessons at controlled speaking and writing drills because these feel safe and predictable, and they reduce behavioural risks (Borg, 2006; Johnson, 1996). However, SLA research (e.g. (Ellis, 2003; Willis, 1996) emphasises that controlled practice (e.g. ‘Oral ping-pong’ or highly structured role plays with prompts) must be a scaffold for freer tasks (e.g. ‘Market place’ or the ‘4,3,2 technique’).

How textbooks contribute: Many activities stop at substitution dialogues or controlled exchanges without providing natural follow-ups where learners need to adapt and improvise.

7. Ineffective Feedback Practices

Research shows that novice teachers frequently struggle with feedback — some over-correct to assert authority, others under-correct to avoid discouraging learners (Borg, 2015; Copland & Mann, 2010). SLA studies (Lyster & Ranta, 1997; Ellis, 2009) demonstrate that selective, targeted feedback works best, especially prompts that encourage learner repair.

How textbooks contribute: Textbook activities rarely anticipate errors or suggest feedback techniques. Their built-in “answer keys” encourage a right/wrong approach rather than nuanced correction.

8. Neglecting Listening Skills

Listening is often treated as “play once, answer questions.” Novice teachers tend to test comprehension rather than teach listening, partly due to limited training in listening pedagogy (Graham, 2006; Vandergrift & Goh, 2012). Yet listening development requires explicit strategy and decoding work (Field, 2008; Vandergrift, 2007).

How textbooks contribute: Recordings are short and often paired with multiple-choice or true/false questions, encouraging a “test what you caught” approach rather than systematic listening instruction.

9. Neglecting Phonics and Pronunciation Beyond the Introductory Stage

While newer textbooks include phonics, novice teachers often treat it as a one-off starter topic. Teacher training research shows pronunciation is often underemphasised in initial teacher education, leading to a lack of confidence and follow-through (Baker, 2014). Yet Woore (2018) and other studies show systematic phonics teaching boosts decoding, fluency, and listening comprehension.

How textbooks contribute: Phonics is now included in starter units, but it is rarely revisited consistently in later chapters. Without teacher intervention, it fades from the curriculum.

10. Ignoring Motivation and Affective Factors

Novice teachers often focus so heavily on curriculum delivery that they underplay motivation. Research on teacher beliefs (Borg, 2015; Williams & Burden, 1997) shows that early-career teachers tend to prioritise knowledge transmission over motivational strategies. Yet Dörnyei (2001, 2014) and Deci & Ryan (1985) demonstrate that motivation, autonomy, and enjoyment are central to persistence.

How textbooks contribute: Topics and tasks are often generic and exam-driven, with limited scope for personalisation. This can make lessons feel distant from learners’ interests.

11. Treating Cultural Content as an “Optional Extra”

Culture is often treated as peripheral. Studies in teacher practice (Byram, 1997; Sercu, 2005) show that many teachers lack confidence in teaching culture, reducing it to trivia or avoiding it altogether. Yet intercultural learning is a key motivator and gives authentic reasons to learn (Liddicoat & Scarino, 2013; Norton, 2013).

How textbooks contribute: Cultural inserts are usually confined to sidebars or one-off pages, which are easy to skip. They rarely integrate with the language focus of the unit.

12. Relying on Teacher Talk at the Expense of Student Talk

Novice teachers often fall into over-explaining and translating because it feels safer than handing control to students. Research (Tsui, 2003; Copland et al., 2014) shows that early-career teachers typically dominate talk time as a classroom management strategy. Yet Swain (1995) and Walsh (2011) stress that output and interaction are essential for learning.

How textbooks contribute: Textbook instructions and activities often assume a teacher-led delivery model, which can encourage too much teacher talk if not adapted into interactive formats.

Conclusions

Beginning a career as a Modern Foreign Languages teacher is a journey filled with both excitement and challenge. The pitfalls outlined here are not signs of weakness or failure but natural stages of professional growth. Every novice teacher has to grapple with the tension between coverage and depth, between control and freedom, between accuracy and communication. The key is not to avoid mistakes entirely — that’s impossible — but to learn to spot them early, reflect on their impact, and adjust.

If you recognise yourself in some of these tendencies, don’t despair: you are not alone. Many of us, myself included, made the very same missteps in our early years. What matters is cultivating the habit of reflection, drawing on SLA research as a compass, and remembering that good teaching grows slowly, like language learning itself. With time, you will find the balance that allows both you and your students to thrive.

Implications for Mentors and Supervisors

For those in supervisory roles, these pitfalls provide a useful diagnostic lens. Mentors, ITT tutors, and Heads of Department can help novices not by prescribing “quick fixes,” but by:

• Framing mistakes as learning opportunities rather than deficiencies, reducing anxiety and building reflective capacity.
• Making implicit beliefs explicit: encouraging trainees to articulate how their own learning experiences and textbooks shape their practice.
• Slowing the pace: reassuring novices that less is often more, and that depth and recycling trump rapid coverage.
• Modelling alternatives: showing how to adapt textbook tasks into richer communicative opportunities, or how to scaffold listening and pronunciation work more systematically.
• Prioritising sustainability: helping early-career teachers manage workload, focus on high-impact routines, and resist the pressure to “do it all.”

In short, supervisors should see these pitfalls not as faults to correct, but as predictable hurdles that can be turned into stepping stones. The role of the mentor is to normalise these challenges, to connect novices with the research evidence that reframes them, and to model strategies that ease the path toward confident, reflective practice.
