Sal Khan represents not just one curriculum, but a new way to thinking about education: teaching basic principles behind the scenes and bringing student participation/collaboration to the fore.

We created ShowMeApp.com exactly for this reason - so that any teacher can easily create these kinds of videos through the iPad and share them online.

Here's a guy who's done a ton of awesome Chemistry lessons: http://www.showmeapp.com/jr_orinion

We're huge fans what Sal is doing and would love to see more teachers embrace his approach.

We're still in beta, but I'd love to hear any feedback on the site and the app.
