I'm very supportive of it if it's on a school level, but I think that everyone has to be on board, otherwise there is parental confusion over it - why does my child have homework but students in Mrs. A's class do not? or why does my child not have homework but students in Mr. B's class do? And, if it's one parent/student in a class, it's "why do we all have to do homework but Abby does not?" Then, you have to either give that child zeros on all assignments or excuse the student from all homework, and is that really fair to the other kids who do complete theirs? Optional homework is okay too, but again wouldn't work in my school culture, in which parents expect students to really be pushed (and to get lots of homework, whether they like it or not). Anyway, though, I digress - I don't think this is the parent's issue with the assignment.
