This is the problem. I was a secondary maths/science teacher. 9 tried to implement a flipped classroom before the pandemic and, well, the kids did absolutely nothing. Most would come to school the next day having never read/watched (I linked videos and actual reading, trying to cover all varieties of ways kids prefer to learn) and be openly proud they didn't. It listed about two weeks before I just said screw it and went back to the normal model because I had to.

Lots of students simply aren't mature enough or lack the disciple/interest to do a flipped classroom - and this will apply to any online education as well. Tech isn't going to magically change education, sadly, at least not the way we conceive of it now.
