Traditional 9th grade geometry sucks.

The more I hear about classroom flipping and the more I read about celebrity tutors, the more I worry about math getting stuck in a downward cycle of lecture, copy, memorize, repeat.

I mean, MAYBE there are people that learn that way. And I certainly know a large, large number of math teachers who think that's just the way math is. It's just that I DON'T, and I'm also a math teacher.
