teachers aren’t “pissed off” because Sal Khan is the world’s teacher. They’re concerned that he’s a bad teacher who people think is great; that the guy who’s delivered over 170 million lessons to students around the world openly brags about being unprepared and considers the precise explanation of mathematical concepts to be mere “nitpicking.”
Experienced educators are concerned that when bad teaching happens in the classroom, it’s a crisis; but that when it happens on YouTube, it’s a “revolution.”
I believe that mathematics should be taught, not collaboratively explored; algebra and geometry are better than a vague course of Integrated Math; spiraling doesn't work nearly as well as learning it properly the first time; "I don't DO math" should be an incentive rather than an excuse. "I don't DO English" should be treated the same way.

The Crisis that is Khan

Some of his lessons are good, some tolerable, some bad. A good teacher will preview them and utilize the good ones, as they would any other good method or program.
