I admire Khan. Although he is not unique in his approach, he is uniquely positioned to deliver this message. By quitting his job and giving away his time, he is an ideal ambassador to the message of "scalable pedagogy". As he has described, if Isaac Newton had recorded his lessons on Youtube, Khan wouldn't have to.

By giving alway classroom tools like test management and monitoring, he is also equipping teachers to become more scalable and as he described - data driven.
