This memo was disappointing--not too much fun stuff, but one line stuck out so I will share it here:
Spending two weeks to review old topics before teaching the new topics is probably not a great idea because you will have less time to teach the lessons. Review also only works for students who forgot not those who did not learn
The man is brilliant. He knows review doesn't work with kids who know nothing to start with. An AP, the master teacher of the department should have an answer. But, his students don't have this problem. They all learn. And, when they don't, they magically get transferred to another class.
(According to Yogi, he was smarter than the average bear, an overestimate of his intelligence.)
