Self-correction is when learners correct themselves instead of a teacher doing it. Teachers can involve learners in self-correction to different degrees, by giving learners more or less guidance as to the location and nature of their errors, and examples of good use of language to compare their own to.
The learner says ‘I feel relax' and then immediately changes this to ‘I feel relaxed'.
In the classroom
Learners can be helped to self-correct with various degrees of help. Using a correction rubric for written homework involves a lot of guidance, but using a facial expression to indicate there is a problem when a learner says something involves less. Giving learners enough time to self-correct in conversation is an effective technique in itself.
