ddrake, I was a college math teacher for many years, and really care about education and enjoyed teaching. I'm curious to hear what #mathed / teaching folks think about Kieran Egan's "The Educated Mind"?

I really like the ideas here. Very, very appealing to a math-y person like me, in that it gives you an abstract framework in which you can make sense of various things related to education.
