Direct answer

Direct answer: Correct errors that block the learner's message or repeat across lessons, and let the rest go. Choose between immediate correction for accuracy tasks and delayed correction for fluency tasks, give the learner a chance to self-correct first, and keep a short record so repeated errors become the next lesson target.

The 1:1 Teaching Bottleneck

Correcting every slip interrupts fluency and makes adults hesitant to speak.
Not correcting at all leaves fossilised errors the learner does not know about.
Corrections given and forgotten leave no evidence of whether anything changed.

A Structured One-to-One Workflow

Decide the task type before the lesson: accuracy task means correct now, fluency task means note it and correct afterwards.
Prompt self-correction first: repeat the sentence up to the error with a rising tone, or say "Try again?".
Prioritise: errors that change meaning, errors that repeat, and errors on the target form.
Write errors on a shared list during speaking and review three of them at the end, not all.
Turn the list into a short task next lesson, then check whether the same errors recur.
Teacher review stays with you: any worksheet built from the learner's errors is a draft until you have read it and corrected the key.

Evidence and Data Flow

Edooqoo has an error-correction exercise type; the tutor can build a task from the learner's real mistakes and edit it before assigning.
Homework answers are reviewed by the teacher, and uncertain text matches are flagged for review instead of being marked wrong.

When this approach works

You teach the same learner repeatedly and can track errors across lessons.
The learner is willing to try self-correction.
You have two or three minutes at the end of the lesson to review the list.

When this approach is not enough

The learner is anxious and silent; focus on confidence before accuracy.
Errors come from a missing concept, which needs teaching, not correcting.
The lesson is a one-off with no follow-up task.

Concrete Tutor Decision

At the end of each lesson choose the one error that most affected clarity and make it the first five minutes of the next lesson.

Adult 1:1 Worked Example

Constructed example. During a presentation rehearsal an HR specialist says "We are discussing since two months". The tutor notes the error and does not interrupt. Afterwards the learner hears the sentence, spots the tense, and fixes it. The next lesson opens with five of her own sentences using "for" and "since".

FAQ

Should I always correct immediately?

No. Correct immediately during accuracy practice and delay correction during fluency tasks so the learner can keep speaking.

How many errors should I correct per lesson?

A handful of the most important ones; more than that overloads the learner and the record.

What if the learner cannot self-correct?

Give a hint about the type of error, and then model the correct form and ask them to repeat it in a new sentence.

Why does feedback matter?

Formative assessment research reports that specific, timely feedback supports learning.

How do I know a correction worked?

Check in the next lesson whether the same error appears in a new task; if it does, change the type of practice, not only the explanation.
