"Khan Academy, a popular online educational resource — more popular, even, than MIT’s OpenCourseWare" Khan Academy is to OpenCourseWare as a castle is to a small, below ground, flat.

Nah, it's for a different demographic. Khan Academy is primarily for high schoolers, whereas MIT is for college students (and beyond).

MIT OCW could definitely learn something about design and ease of use from Khan Academy, though.

Khan Academy has expanded quite a bit and is not just for kids. The sections on Finance and Banking are better than any of the college lectures available. Khan Academy material is generally better than a recorded college lecture because it is designed specifically for web video. Even in the good OpenCourseWare lectures, or similar videos from Stanford, at least half the video is wasted time. I was pretty excited when…

"My conclusion is that college lectures really aren't an efficient way to disseminate education, and they are even less so when they are recorded on video." I'm curious about how you came to the conclusion that lectures are less efficient when they are recorded on video. It seems to me that (for the student which doesn't speak up and engage the instructor in class -- most students?), that a recorded lecture would pro…

The major difference is lectures of Khan Academy, or the new Stanford lectures have a one-to-one lecture format, that probably engages people more.

College lectures, or classroom lectures are non-ideal [1], in an ideal world, each student would have a corresponding teacher. The beauty of technology and Internet is that now we can simulate one-to-one lectures for masses.

[1] There are probably some situations where classroom lectures are better, when the lecture is enhanced by questions via discussion.

For me personally, if I have the opportunity to ask questions, I will think of questions to ask and as a byproduct, think about the lecture more critically. If I am unable to ask questions, I am less likely to think critically. Of course, I have just realized this and now that I am aware of this, I can possibly put a stop to this and get more out of video lectures and even real life lectures where questions are discouraged.

Efficient was the wrong word. The reason videotaped lectures are worse than being there in person: I often can't see the board on the video, and I can't ask questions.

He's also giving the commencement at Rice University. http://www.media.rice.edu/media/NewsBot.asp?MODE=VIEW&ID...

Wow, what an amazing year for him! I enjoyed this recent talk where he spoke a lot more freely than at TED: http://techtv.mit.edu/videos/15484-rethinking-education---sa....

Except MIT's OpenCourseWare has a lot harder stuff. I'm not saying Khan Academy isn't doing good things - it is, but it's designed for a fundamentally different audience, even if there is some overlap. Kahn Academy is for kids, or to get a basic handle on things. For that it is superb, better than anything out there. OpenCourseWare is in general high-level, sophisticated, and far more in depth. Just because you watch…

I really wasn't impressed by the finance/banking Khan Academy talks. They seem worse (adjusted for grade level; they seem to be designed for "general adult, non-academic or professional interest") than the algebra/geometry classes (assuming those are aimed at grades 6-12.)

What I'd like is something at the MBA curriculum level (e.g. Wharton Finance) or the training programs used to bring physics phds up to speed on finance as quants), and executed well. Unfortunately this is probably considered a proprietary/competitive advantage for these firms, so they won't release it.

Younger than high school, too. His lectures on basic arithmetic are really sweet and disarming, good for both grade-schoolers (and remedial adults).
