Research Question. How do teachers correct errors ?

My answer to this question is self correction. During learning period every student makes mistakes and these mistakes makes their knowledge stronger after they learn the correct answer but in this part self correction is the bast way. I want to explain this in detail. when student makes a mistake if the teacher only gives the correct answer, student would'nt have a chance to think about the answer and only accept the answer, of course s/he learn the correct form but in memorization part self correct is the best useful way because when student tries to find the correct answer( during these period teacher support the student and help him/her to find the error) s/he thinks about the mistake and after s/he correct His/her mistake s/he saved it to his/her mind and this kind of correction is long term memorization and student doesnt forget it anytime.
