Sal Khan presents at Gel Conference

If you don't know the Gel Conference by now, you should. Their collection of videos rivals TED. And the founder, Mark Hurst, writes a lovely blog called Good Experience.

One video I enjoyed was this one from Sal Khan, the man behind the Internet's largest classroom. In it, he shares his hypotheses for why his teaching style has been so successful. I was impressed, and I plan to start watching his Biology course.

I left this comment under the video:

There are many testable hypotheses in here, and as a pointy-headed researcher, I would love to see them studied. Here are the ones I counted:

—Teaching works better remotely than in person

—Teaching works better if the students cannot see the teacher

—Blackboards > Whiteboards

—Teaching works better if unscripted / conversational

—Teaching works (a lot) better if the intuition is presented from the beginning and information is distilled down to the “simplest nuggets”
