Mathematical Education by William P. Thurston (1946 - 2012) - http://arxiv.org/abs...
"This essay, originally published in the Sept 1990 Notices of the AMS, discusses problems of our mathematical education system that often stem from widespread misconceptions by well-meaning people of the process of learning mathematics. The essay also discusses ideas for fixing some of the problems. Most of what I wrote in 1990 remains equally applicable today." - JoeCamel
