How many brick and mortar history teachers are doing a far worse job than Khan? Probably a lot.

Ok, so the content can be tightened up, but that's not why Bill Gates is excited here. Take the Khan concept, pick the worlds finest educators in respective fields, build the content, and distribute. That's the game changer here.

When the parent poster advocated having his children taught by a postmodernist, I think he more accurately wants teachers who can make students think for themselves. In the US you can be successful with a boring centrist mindset, you can go to graduate school and become part of the professional/political elite and not really think too much about things. Of course some elites are brilliant thinkers but DC is not exactly a hotbed of intellectual curiosity these days, and governance suffers.

Historical study can reveal a lot about the contradictions of ideology, the gap between political rhetoric/narrative vs reality. For this reason it can be a very politically charged topic. But even boring (to outsiders) topics are hotly contested—historical study is not ultimately the cataloging of facts, is it about the analysis of change in complex systems over time.

Of course Khan lectures are not all encompassing just like his lecture on IPOs aren't but they provide a great deal of entry level knowledge.

If the author ever imagined that WW2 could be explained in one short Khan Academy video his expectations were wrong not Khan Academy itself.

Personally, I believe he is a spiteful fool afraid of a revolution in education.

That comment got me, too, but I don't think it invalidates the other arguments. History teachers need to teach students why history is important, and it's not so you won't be embarrassed when the press asks you about Pal Revere. History teaches us lessons that help us make better decisions today. (In case its not clear, I'm mostly agreeing with you. :)

What caught my challenged attention was the juxtaposition of this:

Mr. Khan stands exposed as possessing a historical perspective steeped in academia’s standard issue, postmodern, left-leaning narrative of cultural relativism, multiculturalism, and moral equivalence.

And then this:

In a sense, that’s what Internet personalization filters are already doing, creating an echo chamber where we only hear what we already believe. We can’t think about what we’ve never heard of.

And here I thought coherence was always a fashionable accessory.

Has a point. The Khan Academy approach is very good for maths, and most sciences. These are cases where you can distil knowledge into a few examples and cases, and it works well. The viewer now has a working, and accurate mental model of whatever they were learning, without having to go through -everything- involved. However, this approach to history and other topics can be a problem. While some of the criticism is s…

"Either have the lesson be able to provide an accurate and correct mental model, or make the learner explicitly aware that what they are learning is incomplete/unprecise/whatever." Khan does the latter, it is called an overview. I think this aspect of the original critic's article displayed his lack of understanding of an incremental and iterative approach. If we waited until he had completed every lecture on history…

FYI, I went to this high-school too, and it's a science and tech magnet school. Granted the liberal arts there are a notch above average, but it wasn't what the school was focused on, and from my experience, the history class was not on the level of a good AP class at other schools (though there certainly are plenty of bad AP classes out there).

I don't think this contradicts Matt's point, since the history classes he took were likely better than average for the US, but I feel he was overstating the quality of them.

History is replete with narrative fallacy. The only semi-accurate sources are from people who witnessed an event as it happened and wrote a blow-by-blow account of it as it was happening with little to no interpretation or explanation - a liveblogging/tweetstream of it, if you will.

Hi Everyone, This is Sal here. I wanted to respond directly on the author's page, but they seem to be having a problem taking comments. The reason why I make history videos is that many people I know (many of whom are quite educated) don't even have a basic scaffold of world events in their minds (or the potential causality between events).

Are you starting to use videos from other people? I'd love to see 3rd party content on the site provided it scored well with both students(attention) and teachers(content).

I think the Khan methodology works very very well for elementary math, and I'm a huge fan of the automatically-generated practice problems. These are more valuable than the videos IMHO.

It's valid to point out that other subject matter may not be well presented by this kind of approach.

On the other hand, it's early days. So fast-forward 20-years when you can download a video-game from Khan Academy that will teach you about Vietnam or the Korean war that is exhaustively researched and curated by a hobbyist and veteran (from both sides) community.

Imagine downloading an interactive demo that shows that even if you target an airstrike to within 1m in an urban area, fragments will travel 500 m into neighbouring apartment blocks.

That would be better than kids learning their military history from CoD.

Thank you Sal for great videos! You are inspiring me to study maths.

I have a Ba in history and agree with the criticism raised in the article, however I also think it is a problem that many people dont even have a basic scaffold of world events.

History is about making choices, what to say and what not to say, and the way to say it, it is not merely about being familiar with major world events. What is a major world event? Lets go with WW2 , then when you dig into WW2, what would you say is a major event? Fall of France, D-Day, Fall of Yugoslavia, or Stalingrad? Whatever you choose you exclude another event, your choices influences the further storytelling. You have to make choices.

The solution for this problem is very difficult, since you have to begin somewhere in your story-telling, and even when choosing where to begin you take a side. And that side is with you for the rest of the story telling.

History is not merely about events it is also about connecting dots, you can begin by choosing any event and really digging into it until you begin to see the wider picture. Going the other way around is far more difficult, when you attempt to give an overview of the wider picture. You get exactly what you would if you picked 2m wide brushes to draw on a wall.

My suggestion instead is to pick really small pencils and draw thinner lines, introduce the students to any event in world history and work out from there. Only then the students could enjoy seeing (and make themselves) the wider connections.

A teacher in a classroom faces the same problems as you (and more, imagine 20 teenagers), so dont worry about it. :)
