Many teachers put a great deal of thought into different aspects of their methodology, which speaks well of their skill as an educator. How can I explain this grammar point clearly? How can I get the student to remember this complicated verb tense? What is the best way to correct students’ mistakes? All of these questions are great ones to ask, but even the best teachers sometimes realize after the student has left that they barely said a word. How much did the student really learn if they were not given a chance to show it? Teacher talk time and student talk time (TTT and STT) are two of the fundamental pillars of solid teaching methodology, and should not be overlooked. They shouldn’t be thought of as a strict ratio (e.g. 20–80), but rather as a lens of self-reflection — one of the most useful tools a teacher can have.
What Are TTT and STT?
First, it is useful to clearly define both terms. TTT refers to any speech that comes from the teacher: explanations of the lesson material, corrections, and even responding to a student question about their weekend. TTT isn’t inherently bad — a lesson where the teacher barely talks is as useless as one where the student can’t get a word in edgewise. Instead, the teacher should focus on whether their speech is purposeful and useful to the student. A concise, clear explanation of modals of probability: highly purposeful and useful. Narrating your own actions or filling silences: unhelpful and unnecessary. The same goes for STT: quantity doesn’t equal quality if the student is only producing one-word answers.
Why STT Matters — And Why Teachers Often Underestimate It
Most of us who have passed through the education system have experienced a class with a teacher who rambles on and on without any opportunity to participate ourselves. If we think back on what we remember having learned from that class, the answer is probably close to zero. The fact of the matter is that language acquisition happens through use, not just observation. STT builds confidence in students, which leads to increased fluency over time. When TTT is too high, a curious thing happens where a student’s lack of fluency is hidden simply because they don’t get a chance to reveal it. Teachers may overtalk for a number of reasons: nerves, habit, fear of silence, or a desire to be helpful. None of them are malicious, but they tend to have a detrimental effect on students’ progress.
When TTT Is Actually Useful
While STT should always be prioritised, it’s worth looking at some moments where higher TTT is allowable, or even critical:
- Presenting new grammar or vocabulary in context
- Giving clear, efficient instructions for an activity
- Modelling a task before a student attempts it themselves
- Providing error correction and an explanation for the changes that were made
What all these situations have in common is that the TTT has a clear purpose and is meant to move the lesson forward. As long as it is kept reasonably concise and is always followed by an opportunity for the student to speak, the teacher is doing their job well.
Common TTT Traps to Avoid
What does unhelpful TTT look like, then? It comes in various forms, some more easily identified than others:
- Echoing — Student: “I like to exercise.” Teacher: “Oh, you like to exercise, that’s great, exercise is wonderful for your body!”
- Rephrasing your own questions before students have a chance to think — “What type of exercise do you like to do? Do you go to the gym? Do you go running? How do you like to exercise?”
- Filling silences instead of giving wait time — “What do you think? Hmm…it’s a tricky one. What could it be?”
- Reformulating student answers that are already correct — Student: “I like to exercise.” Teacher: “Good, but you should say ‘I like doing exercise’.”
As we can see, these examples are unnecessary at best, and confusing or demotivating at worst. Even the best teacher is guilty of falling into these traps at times, and it’s nothing to be ashamed of! Instead, we should be aware of them so that we can consciously avoid them.
Self-Monitoring Tips for Finding Your Balance
The first step to improving your TTT/STT balance is simply knowing what it actually looks like in your lessons — and most teachers are surprised by what they find. If you’ve never done it before, try recording one of your classes and estimating the split. You don’t need to analyse the whole thing: a 10-minute sample from the middle of the lesson, once the novelty of being recorded has worn off, is usually enough to give you an honest picture.
From there, a few targeted habits can make a real difference. When it comes to instructions, writing them out in advance — even just as a few bullet points in your lesson plan — forces you to be concise before you even open your mouth. It also removes the temptation to rephrase mid-activity, which is one of the most common and least-noticed sources of unnecessary TTT.
Another habit worth building is wait time. When you ask a question and the room goes quiet, the instinct is to jump in — to rephrase, prompt, or simply answer it yourself. Resist that instinct. Research consistently shows that waiting just three to five seconds before intervening produces longer, more complex responses from students. The silence feels longer to you than it does to them!
Becoming aware of your TTT and STT is not a one-time fix, but rather an ongoing practice that grows sharper the longer you teach. The teachers who improve the fastest are not necessarily the most naturally talented ones; they’re the ones who are willing to record themselves, reflect honestly, and make small adjustments lesson by lesson. If that kind of thoughtful, growth-oriented approach to teaching sounds like you, we’d love to have you on our team. At Craving, we believe that great teachers never stop learning.
