Then you cut the school day in half, get rid of homework, and find the best-of-breed educators to deliver unidirectional video content with mandatory pass/fail multiple-choice quizzes. Do less than x% of quizzes and you get held back a grade. Teachers are on the clock for what, 8 hours a day? I don't think it's too much to ask for two or three blocks of "office hours" for miscellaneous Q&A or face-time or "random topic of the day". I mean c'mon, we all know half of what's taught in schools these days from K-12 is useless filler material. Teachers must adapt.
