Salman Khan 2011 年 TED 演讲

Salman Khan's TED 2011 talk on Khan Academy. He shows that it goes beyond video lectures to self-paced practice and analytics for teachers, and argues for filling gaps in understanding.

Why HN likes it: HN recommends it to show Khan Academy's real model of mastery learning and teacher tools, often as a rebuttal to critics.

“If you watch his (excellent) TED talk [1], you'll see that his organization isn't just about video lectures”
