Some good points. I always saw homework as practicing what was taught. The maths teaxher explains how to do fraction addition say and the hour of the class is taken up with explaining and some examples. Then homework is just using the fact that solving problems in silence seems like a waste of being in a classroom with a teacher

If it’s just busywork then sure, it has no point besides drilling in some sense of “you will have to organise your time and do this or else”
