Homework is tool for training students. However,in schools,students hate homework,for homework brings them too much stress.But how come?
Homework helps students to review the lessons! That is because headmasters and teachers put too much problems of the same kind on the paper,and that's boring and not useful.Teachers should pick out typical problems and teach students the ways to think.
I hope the system of education can be improved.
