Proof of concept: could students learn more if Khan made mistakes?
So after a thought provoking comment by Mylene, and Frank’s great post on how you need to confront misconceptions in science videos for students to really learn, I got to wondering how effective it would be to create a series of screencasts featuring me solving problems incorrectly, and then challenging students to find the mistake in my work. It took all of about 5 minutes to put this together, and I’m thinking it would be great to build up a library of these.
You can see I’ve got a way to go before my video skills can match Khan’s, but I think there’s something too this. It seems intuitively obvious that if kids have to watch a video to find a mistake, rather than just watching it to get the “yeah, this makes sense feeling” they’ll pay much more attention to it. And when they find the mistake, might this make them more cognizant of the same mistake in their own thinking?
