HOW TRADITIONAL MATH USED TO BE TAUGHT:
This is a link to an article by Barry Garelick on the way traditional math used to be taught.

These educationists had to discredit the ways of the past so that they might change things and for some of them it was a way to tap in to the public funds that flow to "new" ideas!
