  Sorry.

    Never mind the 'sorry', I missed it then and I'm really happy you posted it now.

The information density of video is generally too low for me. I wish there was a text-based version of this.

  Or an option to speed up the video by a factor of 2.

    There used to be a piece of software that would do this for audio tracks, that would actually be really nice for speedviewing youtube videos.

      If you download the videos I think you should be able to speed them up with MPlayer.

  To be fair this is for kids around the world, not for someone who's already got a degree.

Here's an IT Conversations interview with Sal Khan - http://itc.conversationsnetwork.org/shows/detail4386.html http://itc.conversationsnetwork.org/shows/detail4386.html

  Thank you for posting this link. I'm 15 minutes into the interview right now, and while there are no big revelations, it gives context to the whole thing. edit: Finished it, and feeling hopeful about the potential of the web to both make the best teachers much more accessible to everybody, and to create mechanisms to select for those good teachers.

  you're right... Sal received his MBA from Harvard Business School. He also holds a Masters in electrical engineering and computer science, a BS in electrical engineering and computer science, and a BS in mathematics from the Massachusetts Institute of Technology ...but I don't think that he's too poor to buy one. everyone has its own methods to work ;) he surely would draw better images, but I personally think that the quality of the lectures would remain on the same high level :)

Is my sample just poor? I picked a random math video and the first problem is demonstrated wrong. Y = 0, not Y = 10 verbally, the writing on the board is correct but he glosses over it very quickly not catching he said anything wrong (error around 2:00). http://www.youtube.com/watch?v=woqq3Sls1d8&feature=youtube_gdata http://www.youtube.com/watch?v=woqq3Sls1d8&feature=youtu... [Update 1] Watched through to the end and he makes more errors and they caught other errors and put in red bubbles to note them. I appreciate the effort and idea behind the project -- hopefully we can actually get experts to provide quality course materials. [Update 2] Odd, watched more of the math videos and he seems to do a better job on more complicated material -- it could be he's too much of an expert and not patient enough to teach the easier material or just assumes it is easy and even with a few errors people will "figure it out".

Comment seen on youtube: "Yeah...try playing Khan and Obama audio at the same time. It sounds very similar. I feel like the prez is teaching me stats and math."
