18 Sep New TEFL Teacher Mistakes You Don’t Want To Be Making

Starting out as a new TEFL teacher can be both exciting and overwhelming. You’ve just finished your training, you’ve got your first lesson plan in hand, and you’re ready to inspire your students. But no matter how well-prepared you feel, most newbie TEFL teachers fall into the same common traps. One of the biggest? Teacher Talk Time (TTT).

Why Teacher Talk Time Is a Common Newbie Mistake

When stepping into the classroom for the first time, many teachers believe that silence is something to fear. To fill the gap, they overcompensate with talking — explaining too much, giving instructions at too high a level, or even narrating their own thought processes aloud.

This mistake is understandable. New TEFL teachers want to stay in control, stick to their lesson plan, and avoid awkward silences. But too much Teacher Talk Time often means students are listening instead of speaking. And in a language classroom, the more your students speak, the more they learn.

The Shift From Teacher-Centred to Student-Centred Teaching

A key part of effective TEFL teacher training is learning how to make the classroom more student-centred. As teachers, it’s not our job to dominate the lesson but to create opportunities for learners to practise the language themselves.

When teachers reduce their TTT, students become more engaged, confident, and independent. In fact, the less you say, the more your students will say — and that’s the ultimate goal of any English lesson.

TEFL Classroom Tips to Reduce TTT

If you’re worried about falling into this classic new TEFL teacher mistake, here are three strategies that really work:

1. Demonstration

Instead of explaining every detail, show your students what you want them to do. A quick demonstration is often clearer (and shorter) than a long explanation. During my recent TEFL teacher training course, trainees were surprised at how effective it was to simply model the task and let students get started.

2. Awareness

Most teachers don’t realise how much they actually talk. Recording yourself or watching a playback of your lesson can be eye-opening. On my training courses, we record trainee lessons so they can reflect privately on how much time they spent speaking compared to their students.

3. Practice

Like anything else, reducing TTT takes practice. In feedback sessions, I encourage trainees to lead the discussion themselves while I guide and add clarity only when needed. Reflecting on who spoke more — the “teacher” or the “students” — helps them become aware of their classroom balance.

Final Thoughts on Avoiding New TEFL Teacher Mistakes

When you’re just starting out, it’s easy to overlook the importance of Teacher Talk Time. But if you can master the balance early, you’ll avoid one of the most common new TEFL teacher mistakes and quickly build stronger, more effective lessons.

Remember: a good TEFL classroom is not teacher-centred but student-centred. The less you say, the more your students will learn — and that’s exactly the kind of classroom every teacher should aim for.
