That's the "flipped" classroom model, but these days, we talk more about "self-paced mastery" learning or "personalized" learning, which is different. Basically, students should be able to go at their own pace, so they can dive into whichever topics they don't grasp as easily or find particularly interesting, and not worry about having to keep exactly in step with their classmates. That may mean doing more problems, re-watching videos, etc. These style classrooms don't involve students necessarily doing anything at home, they just give students the equipment to learn at their own pace. There are some schools trying it out, using Khan Academy and other resources. I've visited a few and it's neat to see. I've also been doing that model in the weekend workshops I teach, and see definite benefits. No more having to rush the students that need more time or bore the students that got it quickly.
