Interesting collection of different perspectives here. I think that learning to budget time and plan for larger projects and self direct learning outside of class are very useful skills. I think that spending time just to spend time as part of some misguided idea that homework builds character is just foolish.

So as always it's more about the quality. Sure, we can make some kind of logical maximum limit on homework (x min per week based on grade or x number projects per term or whatnot) but it has nothing to do with whether the child is learning anything in class or whether the work is appropriate for them.

I think that some homework can be useful (both for academic learning and executive function skills building). But I will always vote for no homework over pointless homework.
