Hmmm, Dianne, no homework. I've never heard of that. I can't speak as a parent or teacher, but as a former student I had a lot of homework. In the last few years of high school, I would have three hours a night. I don't know how the other students who had sports and extracurricular activities managed.
As with anything in life, there must be a balance. Homework is a crucial learning tool, but hours upon hours in my opinion backfires. It is important to have some downtime to let the brain properly absorb the new information it has taken in.
It is a shame, though, that Dianne's kids are missing out on the benefits that homework can teach.
