The school day is long enough. Kids shouldn’t have to bring it home with them. Plus, homework ruins the entire family’s evening, and in some cases, weekend. Do away with it.
As a kid growing up in the 1960s and 1970s....I lived on a farm. From the moment that I got home....I had chores to do (at least three hours per day). The teachers knew most kids in the class were in that category and set aside 45 minutes in the day for “study”....where you basically did all your homework. I don’t see a big issue with this policy.
An 8 hour day is sufficiently for most adults.
