How to correct a text so that it helps the student
1. It is important to remain at the level of the student, when he is A2, it does not help him, when the correction is on a B2 level.
2. One should try to leave as many expressions as possible. Alternatives can be offered, but the teacher should first take into account the vocabs used by the student.
3. Make the student aware of structure and grammar mistakes.
4. Tell the student to write down the mistakes and new vocabs in a different file.
