Here's a little somethin'-somethin' that Diane Ravitch wrote 7 years ago, something that makes as much sense today as it did when she wrote it. Contrast those words with her talk which I attended a couple weeks ago.
What caused her to lose her mind?
Seven years ago, she was worried about "ethnomathematics", about trying to bend math from a pure science to support liberal social science claptrap. It's reasons like that, Diane, that people turned to charter schools, the testing of at least basic skills, vouchers, and the rest of the school reform movement. It had nothing to do with trying to privatize and deprofessionalize public schools; the former is a response, and the latter we did to ourselves, in part by creating such sputum as "ethnomathematics".
