I think it's better pupils get no or less homework because it is more work for pupils and teacher alike. As kids become older, they get even more homework and then they don't have enough time for their families. By the way: if children have a lot to do, they work until midnight and then they are very tired during the lessons. And it's better for the children to pay attention in the lessons than to sleep during them. Finally, I think that children deserve at least some leisure time after six hours at school.
All these things are reasons why homework isn't a good idea.
