If I recall correctly, Sal Khan from Khan Academy fame has suggested homework and school work should be flipped—video lessons at home and student and teacher interaction on the math problems at school. This has some of that flavor.
It was a purely online course, and the instructor was at a campus I never visited. (We were surprised to learn that we'd need to commute there for the final exam, but I worked out an alternate plan.)
The course materials were all Pearson-provided and hosted on Canvas, so there were video lectures, and the quizzes and tests were automated. Our instructor was just there to keep the backend together, and provide a credentialed face.
I, however, struggled mightily, and so I found the tutoring center, and it was fantastic. It was bustling in the daytime; it had computers we could log into or desks without them. Then the tutors circulated, and we could plug through coursework and raise a flag when we had questions.
It was one instance of a vast support network that is too often left untapped by students, who just aren't aware of what's available, or don't care and resort to cheating, or have a study group where they all sort of muddle through.
Kids won't do that. And there's a lot of classes there.
Though indo agree with his sentiment. Most college lectures are useless and easily replaced with a video. I found my best math professor had us do homework and then the beginning of every class I'd going over it and working out all our mistakes. I felt that he could teach calculus to a monkey he was so effective.
There’s some nuance in getting the right balance of interaction but it definitely works.
