I don't see a problem with working on homework in before/after care, either. I know that during the school year it is common and almost expected for kids in the aftercare program to do their homework during that time.
My daughter is starting a CTY summer course next week. She chose "Inventions." I made sure she was well aware that there would be homework before we signed her up and she seemed perfectly fine with the idea at the time...but we'll see how it all plays out in reality.
I can see how a history class would have a large reading/writing componant. I think the trick might be to have the child choose a class that they will love enough that the homework doesn't seem like work.
