It sounds like flipped schools might work for some definition of "work".
I'd definitely like to see some more thorough studies of this, but it looks like the school they focus on in this article got a lot of benefit from it.
What is a flipped school you ask?
In a flipped school, teachers record their lectures and other materials, and students watch those at home and then do labwork/"homework" at the school.
It sounds like the actual format of these recorded videos is still in a state of flux, but I like the idea of the teachers who have 3-6 minute videos that make it easy for students to rewatch them to grasp things they don't understand.
