I'll preface this response with the acknowledgement that the world is not ideal, and there are some fundamental problems underlying how classes are structured (largely due to the fact that evaluations are based on the achievement of the lowest performers) which poses institutional obstacles to efficient work assignments. That being said, given the (in practice flawed) assumption that the work being assigned is someth…
You are assuming the education of a single class takes precedence over other classes, the education of extra curricular activities, and the education of chores at home. That is a large assumption that I'm pretty sure is invalid. The crux of this problem is that time spent in school is poorly spent for a host of reasons. If you child spends close to 7 hours at school and none of that time was available for the work th…
Im not sure where you get the idea of poor time use from. Out of that 8 hours you need to fit lunch, recess, cumulative transition times, and at least 4 major academic topics (Math, Science, History, Language) plus hopefully a rotating time dedicated to the arts. And you want that to fit into 8 hours on top of the practice required to achieve mastery?
Finally, this is me making a value judgement. Just picking one class, math, I'll go out on a limb and say mastery of basic arithmetic is going to resonate much farther in a child's life than participating an extra hour in extra curricular or chores.
