What’s Wrong With Math Education in the U.S.?
Math education in the U.S.: What we’re doing wrong.
-
The vast majority of the people who teach mathematics in schools know very, very little mathematics. They are not to blame—many are intelligent, caring, wonderful people—but they severely lack training and skills. This includes not just exposure to higher mathematical content; for the most part, they’re not even aware what mathematical problem solving is, let alone how to go about solving problems.

The textbooks are horrendous. They are massive, confusing, uninspiring, incredibly inefficient, and stupefyingly boring. I lack the expressive skills to describe how awful and misguided they are.
Такая это страна, США.
