"In our book, Invent To Learn: Making, Tinkering, and Engineering in the Classroom, Gary and I took what I would consider a fairly even-handed view of the current fad of celebrating "failure" in the classroom. I'm starting to reconsider a more radical stance."

A really interesting look at the Khan Academy, and more, and the bigger "Flipped Classroom" movement. The article contains a potted history of the Khan development as well as some rebuttals from Gary Stager and Sylvia Martinez. An interesting read for all wanting to know more about Khan.
