+1 for the idea that history is more than an "incoherent torrent of factoids"

I heard Khan say recently on the Colbert Report that he read the Wikipedia article on the French Revolution as his source before making his video on the subject.

That's fine for his purposes, but somewhere up the information food chain someone must actually read the sources, weigh them, interpret, compare, and do all the other work of understanding and transmitting history. It's hard to imagine that those 'educated' by Khan can take up this work, or if they do, that by the time they become competent, they will regard his videos as anything other than inconsequential in their effort.

However, I do think it's overblown to say that Khan is any more dangerous than Cliff's notes or similar supposed shortcut to education. And I suspect his math and finance videos might be quite good, based on the response, and on the fact that he actually spent time in school learning math and finance. (But I haven't watched them.)

"It's hard to imagine that those 'educated' by Khan can take up this work, or if they do, that by the time they become competent, they will regard his videos as anything other than inconsequential in their effort."

It's a starting point. A good starting point is more important than is usually realized. The start Khan gives, you can now do in-depth research into the history to flesh it out. Without a good overview to start with, you can quickly get bogged down in the details and lose all interest.

Lord knows that's how history classes were for me. They'd pick 1 tiny piece of it and give you way too much information to process and remember, then move on to the next and ignore the previous info completely... Until the test.

A good overview would have let things settle a bit before getting into the details.

Interesting. Do you now see yourself as deeply engrossed in history and doing the real work necessary to become a competent historian? If so, then your example is a counterpoint to my argument. If not, then we're talking about two different things :)

You may want to try watching a few first. Based on the amount of praise Khan received on HN, I had high hopes. So I did watch a few, and I was disappointed. I'm not sure what I was expecting.

I think on HN a lot of people love the concept of online education that Khan represents, but many have not bothered to seriously try it.

I've tried it. Or rather, my students did.

Back when I was teaching, I know many of my students found Khan more understandable than me (or at least complementary to me). I started encouraging everyone to go watch Khan videos and see if they liked them. Many did, and learned quite a bit from them.

I didn't like Khan that much - his style didn't work well for me. But it worked for many people. It's a lot to expect a single lecturer to be perfect for everyone.

What would be really great is if we had multiple Khans, each teaching in different styles.

Coming into a Khan Academy video expecting visual effects (or any effects for that manner) that make a video "impressive" is missing the point. For many, the lectures of a teacher are lost time. Some students (myself included) have struggled to pay attention, struggled to grasp the material, and struggled to relate. What I wouldn't give for some of the years back that I let lectures pass me by without any understanding whatsoever. Being able to go home after class and watch (and re-watch) Khan Academy videos has been instrumental in my learning.

That isn't to say (and I don't think Sal would say this either) that Khan Academy is the end-all of the new online education. Far from it. But it gives students a new opportunity for easy-to-access lectures, and it gives teachers a new paradigm on the "classroom experience". Check out Sal's TED talk for more on that (http://www.ted.com/talks/salman_khan_let_s_use_video_to_rein...).

As an MBA student, I was a tutor and mentor for local middle-school students, and for some there was the sense that school and education had passed them by. They either weren't interested in learning, or their teachers had given up on them, or their family life wasn't currently conducive to learning. Knowing all the details to Conic Sections, understanding discount rates, or the French Revolution isn't what is crucial for them. Having a learning experience they can control and interact with is what is most important. Khan's videos are by definition eternally patient, and will even wait for you to look something up in Google or on Wikipedia before continuing. There is no shame involved here - only learning. To criticize Sal Khan is a real shame. For a society of scholars to do it is absolutely wrong in my eyes. Good for you Sal, and good luck!

Yes, good point. Now that I look over the comments, everyone seems to say the same thing. That's enough to lead me to believe it should be re-examined. Truth is, I once watched half a video but got bored.
