School will have to rely on homework less. It ia nkt that deep or complicated. It does not require super radical reform.
Ypu can still make the tests and exams checking what students know. There will be less "generate bs at home" tasks and more "come back with a knowledge" which will likely be an improvement.
The burden on teachers is already crazy high. That would only work if we multiply the number of teachers by 3 or so with a corresponding reduction in class size. The education system would collapse due to funding and recruitment issues.
Except for one thing ... Schools tend not to fail many people. When an entire cohort has a different level of ability, standards adjust. Possibly some proctored, standardized exams might be more comparable over time. I have read that, controlling for student demographics, SAT scores (frequently used for US college entrance) were increasing until the mid 2000s and then flat since then.
Yes that's always true for the preceding school, but it really only means that the student needs to work harder or fail later on as the final job enabling exam isn't going to move.
> "generate bs at home" vs. "come back with a knowledge"
They are the same picture!
