Yes homeowork works because see doing homeowork at home given by teacher at school or tusion may be a student gets busy in doing activities like writing at home and may have some study at home.
Now a days parents are saying students are not working at home so i think this is worthy for kids to get their mind in some study level.
It will be better help this in future for kids and students if they regualrly do their honework.
I think homework should be given in such a way where students also get sonethibg new to find and simply they do not copy paste the content with the books or reference books.
Homework means the work given at home for students and complete it and given at the next day to teacher so that students may learn something new and may improve their brain in this activities.
