Doesn’t work particularly well with early primary school kids though. Interactivity is a big part of learning and that’s close to impossible remotely.

The flipped classroom concept itself is nothing new. My issue is with the “remote” part of that. There is value in kids working on an art project together or working in small groups to create a poster presentation, etc. The lecture-homework paradigm might be appropriate for high school, to for younger grades, there really aren’t lectures as much as interactive discussions and hands-on exploration.
