Why don't schools simulate a typical 9 to 5 work week for students and remove homework entirely?
I know this is typical for the US so this is more for US people to respond to. I wouldn't say that it is the best system for work, just wondering about the disconnect.
A couple reasons off the top of my head, 1.) You can't let 20-30 kids loose without it ending in pandemonium, but you need kids to practice time management skills before college. Homework is a time where kids can learn to manage a workload, outside of the controlled environment of school. 2) Kids can't candle a 9 to 5, they need recess and art, and music, and gym to give their brains a break. In the 7.5ish hours that kids go to school, there's probably only 4 hours of work done. (but Bob, I only work like 30 minutes of any given day, and I'm an adult...)
A 9-5 would include time for self-study such as “homeroom” or whatever they want to call it. It’s not like they are going to be in lecture the entire day.
