Is Homework a waste of time ?

People wonder is homework a waste of time. I don't think homework is a waste of time because doing homework means we are taking responsibility of our selves . We are the ones who gain from learning so we should take responsibility for some of our own learning. We can take responsibility by doing homework.When we don't do our homework we are the ones who suffer. We don't get good marks and don't learn as much.We also out in other ways as taking responsibility means learning how to manage our time and how to do things that are most important first rather than the things we most enjoy like playing.Homework then does not waste time , it is part of managing it .Some may say , homework wastes time because homework wastes teachers time. The teacher needs to to design the homework mark each piece individually and tell everyone what they got right and wrong. If all this is not done then the homework loses its value as we need to be told individually what our mistakes are to be able to learn from homework.Teachers could as easily use the classwork to find out who knows what they are doing and who are making mistakes and it would save them time.
