I did this for a course I taught that involved mostly coding. The student watched video lectures before class and took a quiz to make sure they understood the content. In class, I answered questions, showed how to do sample activities by live coding, and the student did activities either individually or in pairs. I gave real-time code reviews while they were working.

I got pushback from the school for using someone else's videos (they really wanted me to record my own video lectures AND teach a live class). I also got pushback for not failing more students. The previous teacher just lectured, never live coded, and never did any code reviews for students. The "active learning" instruction was more effective than lecture based instruction.

Not in America it can't. I've worked for a 15,000 student K-12 online school.It is truly tragic hearing about the home/living conditions that many of the students had to deal with.

>Lectures at home

Because school is a de facto babysitting division of our industrialized society, maybe the best approach is to have a facility for kids to be supervised by non-teachers while watching lectures. Then bring in the teachers for work. Perhaps the best approach would be to have the teachers be online and on demand.

This certainly solves the problem of metros that don't have affordable housing for teachers. Of course there are a million ways for this to go bad in our current society, but it is already terrible, so maybe worth trying something else?

Most of the students won't have the discipline/environment to watch lectures diligently at home.

Not sure how this would scale. Assuming all kids have access to their own computer and high-speed internet, are they supposed to spend 5 more hours at home watching internet lectures?

I don’t think it would, the students can skip watching the lecture and then BS through the collaborative in-class work.

The common name for that is "inverted classroom". Not exactly chairs bolted to the ceiling but more descriptive than a person's name.
