Earlier quoted context omitted.

Everything Kahn says seems to indicate that he doesn't believe in simply "watching a video and drilling on some problem set."

You're right. He does talk about teachers having more time for mentoring, which is great. But I guess my concern is mainly about people's re-interpretation of his message.

One of the fundamental points of the OP was that "The real use of being there in person as a teacher is for interacting with the students."

While I understand your concern in general, it seems unfounded in this case.

Here is a link because ted.com is just as awesome as youtube.com http://www.ted.com/talks/salman_khan_let_s_use_video_to_rein... Also is the youtube video a strange colour red for anyone else?

I can't wait for the subtitles to be uploaded, so that I can share with my friends who can't be bothered to watch something which is not in their language.

I've been looking at the Khan Academy site a bit. I find the exercise dashboard kind of strange. Is math the only available subject? And do you have to go through all the prerequisite exercises to progress to the next ones?

At the moment, yes, math only. We're working to entirely cover K-12 math before moving on.

You can jump to any area or exercise you want at any time. We suggest exercises, but I've seen plenty of 5th graders jump to Calculus and play around with Limits just because it's interesting/challenging and they saw their friend try it.

I actually swelled up in tears when he showed the spreadsheet of student progress, and suggested having the students with red blocks (those who are stuck on a concept) being given help from the students with green blocks (those who mastered it).

That is so beautiful.

And it all started with him tutoring his cousins long-distance while maintaining a busy work schedule. There is something real special about that - willingness to spend "free" time, willingness to tutor in spite of the distance (he was in Boston and his cousins were in Louisiana).

Either of these reasons would have been sufficient excuses for him to not help his cousins. Lucky for them and for all of us that such an amazing talent was so generous with his time and insistent on using technology to overcome the distance barrier.

I've heard countless people rave about Salman Khan and his teaching methods - both here and away from HN. The truth is, I had no idea why he and his teachings were such a big deal... until now . I had seen some of his videos before and read some of the articles about the Khan Academy, but had never given them my full attention. To me, it was just another guy with his own teaching methods. But when I see him talk at T…

This is how we were taught at Oxford. The only problem was, the unmotivated/disorganised students (like myself) often didn't do the reading/studying in our own time and so had to have these extremely painful tutorials one on one with the tutor. Also, I remember when doing Economic Theory, I spent 40 hours reading/studying in a library per week and still couldn't get my head around some of the advanced math and game t…

What's nice is that if the Khan academy system were implemented universally, you would have known right away that you lacked the mathematical background you needed.

> Also, I remember when doing Economic Theory, I spent 40 hours reading/studying in a library per week and still couldn't get my head around some of the advanced math and game theory, and really wish I'd had a teacher to teach me those concepts before the tutorial where we'd go through the problems. It turns out I was lacking knowledge of some mathematical transformations that I hadn't been taught because I didn't specialise in double math when I was 16.

I think this point is actually addressed by the Khan Institute's method of teaching. Lectures are kept very high level, short, and tend to build on each other. So rather than learning in a waterfall fashion, you have the (encouraged) option to go back and learn fundamentals before proceeding. The comments section of his website is actually very good for this; for example, in your situation rather than reading a book in 3 hour stints to learn about, say, game theory, you'd instead be watching a handful of encapsulated 20 min lectures, during which, if you ever ran into trouble, you could query the community and get the more granulated information you'd need to be successful in learning the higher level concept.

I actually think this idea (of which I am also a culprit) is also addressed by the Khan Institute. In normal lecture style learning environments this would happen to me, and the next day if I still didn't get the topic (due to a lack of motivation, aptitude, or both) the class would move on, and students like you and I either got screwed or forced into motivation - which one - screwed or motivated - was kind of random depending on the day. But in the Khan method, there's no reason for a student to move on if they don't get the topic, which still leaves the necessity for students like you and I to get motivated, but (in theory) completely removes the option of a student getting screwed by a class that's moving past said student's current level of comprehension.
