Ha, free recess all day sounds nice :)

The more accurate way to describe these situations is overwhelmed teachers with overflowing classrooms where students are left to their own (rather than schools fully absent of an adult).

Recommended Bloomy usage is ~30 mins per core subject. So certainly not the whole day. I have my own very strong misgivings about screen time for kids.

So the idea in this situation is individualized instruction of skills that can adapt live to a student, in a concentrated and limited period of tech time. Hopefully this creates a better outcome than the status quo.
