Very interesting and thoughtful. But I think the author gets it dead wrong.

"the budget cuts he seemed so giddy about invariably mean fewer teachers, and to argue that this is somehow beneficial to learning is to argue against years of research and practice" -- this is exactly the argument that Khan Academy is making: that we can cut teachers in favor of lessons taught by computer. The actual reason why "this time is different" is that we now have the power to create excellent lessons, through the power of computers, the internet, and crowds.

Maybe Khan Academy isn't good enough to replace teachers yet. (I would be surprised if it weren't already better than 75% of teachers, though. Most teachers aren't very good.)

Another claim the author makes: "Khan Academy makes it difficult for something better to come along" -- I would be SHOCKED if this were true. Sure, it's hard to compete with free, but KA is creating a new ecosystem of people who are looking to the internet for teaching materials! So if KA is really as bad as the author claims, then it's going to be MUCH easier than it is today to get better materials in the hands of kids.

Silly article. It offers no proof to their statement that students learning through Khan are on a "wild goose chase" for correct answers except for a 1973(!) paper. I believe it to be the opposite, the chances of you just guessing 10 correct answers in a row is ridiculously low. It encourages you to make sure every answer is correct before submitting it, otherwise you would have to start over again.

It doesn't address the issue that each student can learn at their own pace, which is the main part of Khan. It ignores people that had success with KA except for a quick mention. It also ignores the fact that Khan is a great teacher, and with this model anyone can learn from the best teacher there is.

It ignores the tools it gives teachers to see the progress of the students. It ignores the fact that teachers can give personalized assistance. it ignores that more advanced students can teach less advanced students.

It dismisses the achievement system while every single educator knows they work and have worked since the first teacher decided to give students gold stars. It only mentions it in passing to say that it doesn't work without offering any proof.

The truth is: There are a LOT of people who have their own idea of what the "perfect" teaching system is. When something comes around that challenges that, as with everything else, those people will try to say that it won't work. Let it be field tested, let's see the results. THEN we can say if it works or not.

EDIT: I forgot to say that it also ignores the fact that students can only advance once they completely mastered the subject. It doesn't mention that it puts the power in the hands of the students and let them take control of their own education by deciding which classes to take and when to take them. And as someone mentions, the author is also biased.

Its weird that he complains that khan teaches the same that has been failing for generations, then goes and slams him for not hiring teachers (the people who have been teaching the same way for generations).

The article was super long and I bet most people won't make it down to the bottom where he goes on to explain that he actually likes khan academy and how it's a great thing. Too bad.

The truth is that Khan Academy is helping millions of people - and I'm one of them - to learn topic that seemed out of their reach. Maybe KA hasn't understood all of the pieces of the educational puzzle, but given their resources and trajectory I think they can have the same kind of profound impact as Wikipedia.

It's a contradictory rant and it's not obvious what the author wants from the reader beyond us purchasing his product. Ok, maybe that's a bit harsh but I honestly don't know what the takeaway is. Maybe it's the realization that KA isn't the answer to all our educational challenges, but that seems like a straw man. Given how many problems KA has solved for so many people, I think it has more than justified its existence, educational approach, and resource pools and funding.

Its easy to ignore all the thousands of students, like me, who have improved and understood concepts I hadnt learned before in formal school. We arent really visible, its like we dont exist.

Just as I havent seen anyone improving their understanding of mathematical concepts from the mathalicious school.
