My feelings now are that there really shouldn't be any mandatory homework.
- If you do it badly, you may as well not do it. Who else remembers flipping through "The Catcher in the Rye" so fast they don't actually remember any other character than Holden Caulfield?
- It's an easy way for teachers to not teach, yet gives them an alibi. "Look I'm teaching, they have loads of books to read. Can't help it if they don't."
- If you already understand it, you don't benefit from solving more quadratic equations. You benefit from doing whatever the next step is. You just burn time plugging things into (-b +- sqrt (b2-4ac)) / 2a. And you learn the wrong lesson, which is that you have to get it exactly right, rather than why that's the equation in the first place.
- You end up testing which kids have peaceful homes, and parents who care. Some kids just can't do any homework with the home environment they're given. School should be such that it doesn't matter if your parents are drunks or academics.
- Totally fine with doing like in University: here's a mega list of interesting things related to the subject, go and browse around, get a feel for what the landscape is like. Come back more interested.
