I'm close to someone who teaches at a university, and they're making heavy use of in-room essays written in blue books. This ensures that the work is purely the students, but I think it also has the side-effect that the grader is also working manually. I kinda think maybe at earlier levels, most homework should be moved into the classroom and done on paper anyway? What's the point of homework if they're not going to…
My theory is that most homework is given to ensure the parents take an active interest in the kids education.
The fact that the kid needs help to do it is part of the goal, but completely impractical in a small family with 2 working parents.
Unfortunately, the homework is all done in the after-care program, where the high school kids who work there spend the time getting the homework done.
Not exactly what the teacher intended.
