The problem with math education is a lot more basic then everyone pretends: there are two variables, mastery and time and we made the wrong one static.

This was a global decision born out of necessity. Because there aren't as many teachers as students we had to make time static and mastery variable. You take a class for a set period of time and then you get a grade based on how much of it you understood. A B means you understand the topic about 80%. In an ideal world every student would always get 100% but simply move at a different pace with the best students simply consuming more material throughout their school career (calculus, linear algebra, etc).

The tremendous news is that technology can and will turn this on it's head. The Kahn Academy does this already with tremendous success and it's the single most important thing that has happend to education in a long time.
