Don’t be fooled, correcting mistakes is a fundamental part of being a teacher. The essence of a TEFL teacher is to be able to teach new stuff as well as getting students to practise the stuff they should know and to make sure they are using it and saying it correctly.

The first thing you need to do is to get comfortable with the concept of correcting. Correcting is not rude, it’s your job. Your students actually want you to correct them and start to get upset if they feel a teacher is not correcting them enough. So you don’t need to worry, you are not offending anybody.

You need to start tuning in. In the UK, with such a variety of nationalities and with a wide spectrum of English ability, a lot of us have got used to hearing imperfect English. Literally, as long as we understand what’s being said to us, we sometimes don’t even register any mistakes.

There is a slight difference between a mistake and an error. A mistake is something we all make, even in our own language. You can recognise a mistake by the fact that we clearly know that it’s wrong and as soon as someone highlights it, we are able to self-correct. An error, on the other hand, can be classified as:

  • a mistake that the student thinks is actually correct;
  • a mistake the student makes because they don’t know the correct form so they just guess;
  • a mistake the student often makes. They know the correct form in theory but they can’t seem to use it correctly in practice.

What and When to Correct

What to correct

When teaching a vocabulary or grammar lesson, the teacher should focus on correcting the structures being taught. Remember, it is much harder to change a bad habit than it is to create good habits. You also need to keep an eye on mistakes that really make it difficult to understand the speaker, eg because the wrong word is used or the pronunciation is too poor to be able to recognise what is being said.

When to correct

We know there are 3 main parts to being a good language speaker:

  • Accuracy – being able to produce the language accurately;
  • Fluency – being able to talk at a natural speed without having to continuously pause to find the right word;
  • Confidence – being confident enough to feel able to communicate, with the result of participating actively in communication tasks.

As a general rule, some nationalities naturally have more focus on one attribute than the other. For example, many Asian students don’t like to speak in class because they fear making a mistake and do not like to feel embarrassed in front of their peers. Italians, on the other hand, are quite happy to stumble along and seem to mind less if what they are saying is accurate, more important is that they get the point across and can make themselves understood. During a vocabulary or grammar lesson, when we correct is important. There are two main types of correction:

Instant: We immediately correct the mistake. This is vital during the Present and Practice stages where the students are learning the new material and learning how to use it correctly. Here, it is important that students are accurate.

Delayed: We wait until the exercise is over before we correct. This is the main strategy used during the Perform or Production stage. Here we are trying to improve the students’ fluency and confidence and we think an interruption will cause them to lose their thought process and confidence.

How to Correct

During the Presentation and Practice stages of a vocabulary or grammar lesson, we focus on teacher correction because we are pretty sure they don’t know the material or are just learning it. But during the Perform part of a vocabulary or grammar lesson and during a skills lesson we have more correction methods available to us. Generally, the method we use to correct depends on the type of mistake.

If we feel that our student believes they are speaking correctly or guessing the correct word or structure, then we rely on either teacher correction or peer correction.

If we are confident that the student knows or should know what the correct word or structure is, then we use self-correction techniques.

Self-correction prompting

Stage 1 – the face

When we want the student to self-correct, we look at the student, making eye contact and then we ‘make a face’. The face should signal to the student that something they said wasn’t quite right. Often, the face can be described as similar to unexpectedly eating something sour like a lemon. If you make the face every time the students make a mistake, then they will quickly learn what it represents and will replay what they have just said (in their head).

Stage 2 – repeat the mistake

Next, we repeat the sentence with the mistake in but make the tone questioning. If the student is not sure, we repeat the sentence again, this time really emphasizing the word that is wrong.

Stage 3 – breakdown the word

Once we have given our look and repeated the sentence accentuating the mistake, we then start to say the word a syllable at a time, waiting for the student to jump in and finish the word. For example, the teacher says: “My father likes pho…….to……….gra……….phy

You will find that nearly every student has the odd word or structure they just can’t seem to learn or use properly. They understand what it is and how it’s said but it just doesn’t seem to stick and the student can’t seem to remember. You can help them by identifying the problem every time they say it so they get plenty of practice at correcting it. Things to look out for are:

3rd person                S He like_ fish

He/She                     (my father) she likes fish

Have/ Has                (my father ) he have a fish

Written Corrections

The idea that self-correction, rather than teacher correction, is the most effective method is true when correcting written work. You start by taking a pen that is of a different colour than the colour the work was written in. (Red is obviously traditional but these days some people consider red to be too aggressive and have taken to using friendlier colours). Ideally, you want to be able to highlight the mistake by underlining the word or sentence (perhaps writing a hint in the margin) and giving it back to the student to self-correct. Then, you correct the corrections they have made.

Bear in mind that a page full of red ink is pretty disheartening to a student. It may be that you decide to select some of the more important or bigger mistakes and leave some of the smaller ones to pick up next time.


If you have a class of students that are comfortable with each other, then you may rely on peer correction for both verbal and written corrections. It is a great tool as they learn to analyse themselves and each other. Please be aware that there are some cultures that are really uncomfortable being corrected by their peers and also some where people will feel uncomfortable correcting someone they consider to be in a position of respect or authority (a boss or an older student).

Correcting Pronunciation

With so many things happening at the same time, it can often be difficult, especially in the first few months, to keep on top of everything. One of the things that often gets lost in the confusion is correcting. A tip to prepare yourself for being able to correct is to have in your head the kind of mistakes you are going to hear. This is really easy to do when it comes to pronunciation problems. Most nationalities have their own battles with English pronunciation. As a teacher you can help yourself by researching on the internet what the normal problems are. Simply type in the search engine for example “Chinese pronunciation problems” and you will get plenty of information. It is the same as most things: the minute you are aware of it, you hear it all the time.
