How to correct ESL speaking mistakes without stopping the conversation

Correct too little and the same mistakes keep coming back. Correct too much and the student stops talking. Here is how to choose, with what to say.

Your student is in the middle of a story and says I am agree with my boss. Do you stop them or let it go? Tutors make that choice many times a lesson. There's no single right answer, but there are good ways to decide, and a few ways to correct that keep the conversation going.

First, decide what the activity is for

  • Accuracy practice, such as reading answers aloud, repeating new phrases or practicing the grammar you just taught: correct straight away. Getting it right is the point.
  • Fluency practice, such as a conversation, a role-play, a debate or telling a story: correct very little while the student talks, and do most of it after.

Tell the student which one it is: "For the next ten minutes I won't stop you. I'll take notes, and we'll look at them after."

Which mistakes to correct

Correct these:

  • Mistakes that change or block the meaning. I'm boring when they mean I'm bored. I worked here for two years when they still work there. I walk in a bank when they mean work.
  • Mistakes the student makes again and again. One wrong past tense is a slip. Ten in a row is a habit.
  • Mistakes in what you're teaching today. If the lesson is about the present perfect, that's where your attention goes.
  • Mistakes that matter for the student's goal. A salesperson who says You must send it today to clients sounds rude without meaning to. A student preparing for interviews needs past tenses that hold up.

Let these go, at least for now:

  • Slips. If the student usually gets it right, it was speed or tiredness.
  • Language above their level. An A2 student telling a story with only the past simple is doing fine, even where a fluent speaker might use the past perfect.
  • Small mistakes in a story they care about. Wait until they finish.

Recasts: say it back correctly and keep going

A recast is your reply with the mistake fixed, said as part of the conversation:

  • Student: Yesterday I go to the dentist.
  • Tutor: Oh, you went to the dentist? Is everything OK?
  • Student: Yes, I went for a checkup. Everything's fine.

A recast doesn't stop the conversation. The weakness is that students often don't notice it, because it sounds like you're agreeing. To make it easier to notice:

  • recast only the part with the mistake, not the whole sentence;
  • stress the corrected word a little: "you went";
  • use a questioning voice, as above.

If the student says the correct form back, as in "Yes, I went," the recast worked. If they carry on with go, it's a mistake to note for later.

Prompts: let the student fix it

A prompt tells the student something is wrong and gives them a chance to correct it. When they find the correction themselves, they do the thinking, and you learn whether they know the rule or not.

  • Repeat up to the mistake: "Yesterday I…?" Then pause.
  • Give a choice: "Go or went?"
  • Give a short clue: "Past." "One word is missing." "Not make. Another verb."
  • Ask them to say it again: "Sorry?" or "Say that again?" This works best with students who know the signal.
  • Use a gesture, such as a thumb pointing back over your shoulder for the past. On a video call, agree on it in advance and keep your hands in the picture.

Use prompts for mistakes the student can fix, such as grammar they've already studied. Recast language they couldn't be expected to know. If the student can't fix it after one try, give the answer and move on. A correction shouldn't turn into a quiz.

Delayed correction with notes

During a fluency task, write down what the student says, word for word, and keep going. Next to each sentence, write a better version. Note one or two sentences that were good, too.

  • I am agree with you. → I agree with you.
  • He explained me the problem. → He explained the problem to me.
  • I have 34 years. → I'm 34.
  • I've been to Lisbon last year. → I went to Lisbon last year.
  • Good: It was much harder than I expected.

After the task, show only the student's sentences. The student corrects each sentence, you help if they're stuck, and then they say the corrected sentence out loud. For the mistakes that matter most, ask for one new sentence of their own with the correct form.

Some tutors type corrections into the chat while the student speaks. It's quiet, but some students start reading while they talk and lose the thread. If that happens, keep the notes to yourself until the end.

How to give feedback after a speaking task

Use the same order each time, so the student knows what's coming:

  1. React to what they said. "So you'd move to Lisbon for the weather? I didn't expect that." They were talking to tell you something, so answer it first.
  2. Say one or two specific good things. Not "Good job," but "You used although twice, and both times correctly."
  3. Work on three to five mistakes from your notes, with the student trying first.
  4. Do the task again, or a shorter version of it. The second try uses the corrections while they're fresh.

A sample of what the tutor might say:

"That was a good story, and I loved the part about the lost ticket. You told it in order, and suddenly and in the end worked really well. Let's look at four sentences. Here's the first one: I've been to Lisbon last year. What would you change?"

How many corrections are too many?

There's no fixed number. Watch the student instead. You're correcting too much if they:

  • start sentences and stop halfway;
  • look at you before they finish a sentence;
  • give shorter and shorter answers;
  • say "sorry" a lot.

A rule of thumb for free speaking: interrupt only for mistakes that block the meaning, note the rest, and choose three to five to work on at the end. In accuracy practice, correct most mistakes with the target language.

It also helps to ask the student. Some want every mistake corrected. You can agree to correct everything in the accuracy part of the lesson and send a full list of your notes in writing after. Others want fewer corrections so they can build confidence. Ask in the first lesson, and ask again after a month.

Pronunciation

Correct a sound when it changes the meaning or makes the listener work hard: walk and work, live and leave, ship and sheep. Word stress matters too: COMfortable, not comFORtable. An accent on its own isn't a mistake. If the student is easy to understand, leave it.

If you teach on SnappySchool, write the "you said" sentences on the whiteboard during feedback and let the student correct them there, so both of you are looking at the same sentence.

Questions

Should I correct every mistake my student makes?

No. During free speaking, correct mistakes that block the meaning, note the rest, and work on three to five at the end. During accuracy practice, correct most mistakes with the language you're teaching.

What is a recast in language teaching?

A recast is when the teacher repeats what the student said with the mistake fixed, as part of a normal reply. "I go to the dentist yesterday." "Oh, you went to the dentist?" It keeps the conversation going, but students don't always notice it.

Is it better to correct mistakes right away or later?

It depends on the activity. Correct right away during accuracy practice, and later during conversation, role-plays and stories, using notes.

Should I correct my student's pronunciation?

Correct sounds and word stress when they change the meaning or make the student hard to understand. An accent on its own doesn't need fixing.

What if my student asks me to correct everything?

Agree on a middle way. Correct everything during accuracy practice, and during conversation take notes and send them all in writing after the lesson. That way the student gets every correction and still gets to talk.
