Errors are a natural and necessary part of language learning. Effective correction does not mean correcting everything students say or write. Teachers need to decide what to correct, when to correct it and how to correct it.

The purpose of correction is not simply to show students that something is wrong. It should help them notice the problem, understand it and produce a better version themselves whenever possible.

1. Decide whether the error needs correcting

Not every mistake requires teacher intervention.

Prioritise errors that:

• involve the target language of the lesson;

• interfere with communication;

• are repeated frequently;

• are common across the group;

• involve language students should already control at their level.

During a lesson on the Past Simple, for example, repeated errors with past forms deserve attention. A minor mistake involving language considerably above the student’s current level may not.

Correct selectively and purposefully.

2. Accuracy or fluency?

The timing of correction should depend on the objective of the activity.

Accuracy-focused activities

When students are specifically practising a grammar structure, vocabulary item or pronunciation feature, correction can usually be more immediate.

Student: “She go to school every day.”

Teacher:

“She…?”

Student:

“She goes to school every day.”

Fluency-focused activities

During discussions, role plays or longer speaking tasks, constantly interrupting students can damage fluency and make them reluctant to communicate.

Instead, monitor the activity and note important errors. Afterwards, conduct delayed feedback with the group.

The principle is:

Accuracy work → more immediate correction

Fluency work → more delayed and selective correction

This is a guideline rather than an absolute rule.

3. Encourage self-correction first

Whenever students have the linguistic knowledge to correct themselves, avoid immediately giving them the answer.

Use eliciting:

Student: “People is becoming more dependent on technology.”

Teacher:

“People is…?”

Student:

“People are becoming…”

The teacher can also indicate the type or location of the error:

“Check the verb.”

“Past tense?”

“One word is missing.”

“Can you say that again?”

This encourages students to retrieve what they already know instead of passively receiving the correction.

However, do not continue eliciting indefinitely when the student clearly does not know the answer. At that point, provide the necessary support.

4. Use peer correction appropriately

Students can sometimes help each other identify and correct errors.

For example:

“Compare your answers with your partner and explain any differences.”

or:

“Can anyone help with this sentence?”

Peer correction can promote collaboration and language awareness, but it should be used carefully.

Avoid turning correction into a situation where stronger students continually correct weaker students publicly. The teacher remains responsible for confirming whether the final correction is accurate.

5. Use delayed correction

During speaking activities, monitor students and collect examples of language.

Afterwards, write selected sentences on the board without identifying who produced them:

I am agree with this idea.

People is spending too much time online.

Ask students to work individually or in pairs to improve them before checking together.

Delayed correction allows the whole class to learn from errors without constantly interrupting communication.

Do not only collect mistakes. Include successful examples too:

✓ One of the main advantages is that…

✓ Although I understand that argument, I would say that…

Students should also notice what they are doing well.

6. Give specific feedback

Avoid feedback that consists only of:

“Good.”

“Excellent.”

“Wrong.”

Students need to know what was successful or what needs improvement.

Compare:

“Good speaking.”

with:

“Good. You gave your opinion and supported it with two clear examples.”

Or:

“Your answer is clear, but try to develop your reasons rather than giving one-sentence answers.”

Specific feedback helps students understand what they should repeat or change next time.

7. Correct according to the student’s level

Expectations should reflect the level being taught.

An A2 student and a C1 student should not receive exactly the same feedback for the same performance.

For example, frequent repetition of good, bad and very nice may be acceptable at lower levels but should increasingly be addressed as students progress.

At higher levels, feedback should encourage greater:

• accuracy;

• range;

• precision;

• complexity;

• organisation;

• fluency;

• appropriacy of register.

In Cambridge preparation classes, teachers should also relate feedback to the assessment criteria of the corresponding examination.

8. Do not correct by simply repeating the wrong language

Be careful with exchanges such as:

Student: “Yesterday I go to the cinema.”

Teacher: “Yesterday I go?”

Repeating incorrect language without a clear corrective signal can sometimes create ambiguity.

Use intonation, a prompt or a direct indication:

“Yesterday… past tense?”

or:

“Try that again using the Past Simple.”

The student should understand that a correction is being requested.

9. Give students time to act on feedback

Feedback has limited value if students read or hear it and immediately move on.

Whenever possible, students should do something with the correction:

Notice → Correct → Produce again

For example:

Student gives an answer → teacher provides feedback → student improves and repeats the answer.

In writing:

Teacher/AI identifies an issue → student attempts to correct it → student compares and understands the correction → student rewrites the relevant section.

The final step is important. Students need opportunities to produce the improved language themselves.

10. Balance correction with recognition

Feedback should not become a permanent search for mistakes.

Teachers should also highlight:

• effective vocabulary;

• good pronunciation;

• successful use of recently learned grammar;

• improvement from previous lessons;

• well-developed answers;

• effective communication strategies.

Recognition should be specific and genuine, rather than automatic praise.

“You used although accurately there. That’s exactly the type of linking we have been practising.”

This helps students understand what successful performance looks like and encourages them to repeat it.

Remember

Effective correction should help students become less dependent on correction, not more dependent on the teacher.

Whenever possible:

Give the student a chance to notice → elicit → allow self-correction → provide support if necessary → confirm → encourage the student to use the corrected language again.

The objective is not for the teacher to demonstrate that they know the correct answer. The objective is for the student to learn to produce it independently.
