Keith Devlin has a review of the chronology in part and of criticisms of Khan including his own prior to June 18, 2012.
(I used this as a first draft of the chronology, including copying links in some cases. I submitted a comment but it never appeared. Nor have I seen any other comments not by Devlin as of this date (July 7 2012).)
Devlin’s article has additional links especially to older criticisms of Khan including his own.

(This is one I noticed another person’s comment disappear while I was checking one or two of mine. I and someone else responded to a Donald McKendrick comment that Talbert later responded to. Perhaps Talbert removed our two responses or perhaps Chronicles did. From the other comment’s mild vanilla content this seemed more likely Talbert removing them, since I see no reason for Chronicles to have done so. In either case, it is ironic since Talbert claims to have been causal in prompting his colleagues to create the first Khan video critique.)

#MTT2k Khan Academy Put Call Parity Video
The following video uses Popcorn to point out an error in Khan’s Put Call Parity Clarification video.
The other Khan Put Call Parity videos do not have this exact mistake, but their approach differs from the standard explanation in a way that makes it harder to learn and fails to teach the concept well. The standard way is based on actual class room experience teaching MBA students and others for over 20 years at many schools.
Salman Khan is the Founder, Executive Director, and Faculty of the Khan Academy, whose mission is to provide a free world-class education to anyone, anywhere. He has worked for both hedge funds and Fortune 500 companies and holds an MBA from Harvard Business School, where he was the president of his class. He also attended MIT, where he received three degrees: a Masters in Electrical Engineering & Computer Science, a B.S. in Electrical Engineering & Computer Science, and a B.S. in Mathematics.
Note that they mistakenly make Khan president of his HBS class instead of his MIT class.

Using Popcorn Maker in style of Kate Nowak, I post my popcorn video critique of Khan’s Put Call Parity Clarification video. This has an embedded link in the video to her post as the first one to do this. Such embedded working links is an important feature of Popcorn Maker.

==Censorship at Magazines and the big blogs
Chronicles removed not just some of my comments but those of another person as well. I refreshed a page at one point to try to see if mine showed up and someone else’s comment disappeared! I also noticed someone’s comment at Wired complaining their comments had not appeared in 5 days. I also had that problem there. So it appears that at the magazines and the bigger blogs there is some censorship.
In addition, my criticism of Khan’s Put Call Parity Clarification video is relevant in part to other of his Put Call Parity videos. Some of those others are posted at CNBC to teach Put Call Parity to investors. So in keeping my links to my criticism of Khan’s Put Call Parity investor out, they not only don’t help this contest, they hinder getting the word to investors who rely on the CNBC put call parity pages using the Khan videos. The blogs are not really culpable here, since a personal blog is personal, but the magazines are culpable to harm investors this way. They hold themselves out as helping the public, not hindering it learning of errors in investment videos because of their need to keep the person who pointed out the error from getting credit.

“How Khan Academy Is Changing the Rules of Education”
By Clive Thompson
July 15, 2011
February 4, 2012
(An important piece pointed out by Devlin July 1 2012)
In addition to the cases pointed out above, I have noticed in several comment threads complaints about censorship of comments. The censored nature of the debate on Khan Academy especially by seeming independent magazines like Chronicles suggests that teachers and parents have very little chance for a free public debate before high stakes testing and major changes in the nature of the classroom and teaching are implemented.
The drop off in views of later videos, two of them under 100 views as of July 7 2012, indicates that Bill Gates has no real opposition to mass firing of teachers based on teacher testing and substituting Khan videos for teachers at least by higher student to teacher ratios and using lower paid guest worker teachers.
Firing teachers and replacing them with guest workers at low pay and no pension accrual may be what Bill Gates is really after, because his TED talk on state budgets indicates that unless spending on teachers and teacher pensions is substantially reduced, state income tax rates on Bill Gates and Silicon Valley and Wall Street Bloomberg type moguls will rise substantially.
High stakes testing and Khan Academy videos may be just ploys for Bill Gates and the other moguls to cut the cost of non-visa teachers and teacher pensions to keep state income tax rates on the wealthy from rising to between 10 and 20 percent. Every teacher fired from high stakes testing can be replaced by a visa worker without pension benefits at lower salary. If this happens to enough teachers, the teacher unions will be broken and pensions can be gutted for all teachers. In addition, salaries can be slashed for all teachers.
If state income tax rates rose to between 10 to 20 percent on high wealth individuals it would be the bad old days for the wealthy. This would be in addition to federal income tax rates that with the budget deficits could rise to close to 50 percent by themselves shortly. Add to that higher state income tax rates of 10 to 20 percent and you get 60 to 70 percent income tax rates on the wealthy. That is something they do pay attention to.
Bill Gates and other moguls have the power of persistence. They also have the power of sustained attention. Those opposing them have neither it would appear.
If this is true, the critique of Khan Academy videos that has dwindled to under 100 views and now sometimes consists of censoring comments at magazine articles is not going to present any serious opposition.
Bill Gates: How state budgets are breaking US schools
Filmed Mar 2011 • Posted Mar 2011 • TED2011
If you look at only one video from start to end, look at this one. This video is the one that says Khan Academy videos are going to replace teachers to save the moguls from the return of income tax rates of 70 percent. This is the one that lets us infer that the purpose of high stakes testing is to fire teachers so they can be replaced with visa workers at low pay and no pensions. This is how they will break the teacher unions and end teacher pensions for all. This is how they will slash teacher pay.
Don’t take your eye off the ball. Bill Gates tells you what the ball is in the video. We can infer that Bill Gates is telling state legislatures in this video to fire teachers who have pension benefits accruing and replace them with visa workers with no pensions and low pay.
The other audience is other moguls. We can deduce that Bill Gates is telling the other moguls to get behind mass teacher firings and use high stakes testing as a ploy to justify mass teacher firings to gut pensions and break the unions.
College professors at state schools, Bill Gates has not forgotten you either. He wants the same high stakes testing for college teachers. This can get them fired with a loss of their tenure and pension accruals.
Bill Gates is a man who thinks things through. He then works hard to convince other moguls to see things his way. Is Bill Gates capable of pushing Khan videos and high stakes testing as a ploy for mass teacher firings? You betcha.

“Nothing New about Teaching from Bill Gates”
By Walt Gardner on October 25, 2011 7:43 AM
The Bill Gates program of getting moguls to leave billions to foundations and universities is in effect a way to create a permanent super class of wealth. It is a permanent oligarchy party that controls all establishment institutions including the top establishment political parties in each country.
The money left to foundations escapes death taxes. But then is controlled by interlocking boards of moguls. The money is then used not for real charity, but to slash and burn the teaching profession and break the teacher unions. The purpose is to use these interlocking foundations and charities endowed with billions of wealth to dispossess workers of any say in their lives or in politics. Both parties have the same platform on visa workers, more. Both parties are about transferring wealth from the middle class to the oligarch class.
The foundations and universities simply create conclusions of science like high stakes testing and teacher firing will improve student outcomes. They just decide that videos and testing software replace teachers, especially the bottom half of teachers. Eventually, the bottom 90 percent of teachers. Teaching is lowered from a profession to just a monitoring service that can be done by anyone. Already Virginia Tech has a giant building for exactly such courses.
This is like replacing doctors and nurses by machine attendants and medicine is simply dispensed by computers. The foundations can simply declare this is good science and then the establishment parties make it part of their actual government policies, whatever they pretend to voters. People move from the foundations to the policy making positions in government and just implement the policies the foundations have decided on. It is rule by foundations. The oligarchy controls the foundations and uses those as a proxy to control government policy.
We have seen this with the banks. Bank regulation becomes meaningless at the same time. Even when the banks are caught in outright fraud, nothing serious happens.
Bill Gates had a bad experience with the Antitrust Division of the US Department of Justice. This is what he has come up with so that neither he nor any other mogul will have to go through that again.
The moguls don’t just have the power of money. They have the power of persistence and sustained attention. As pointed out above, already the newer videos in the #MTT2K contest are getting under 100 views in their first day or two. The only ones who sustain an interest are the moguls and a few outliers who are in effect heard by so few people that they don’t exist.
