The attacks on Khan here personally irked me.
I grew up in a small rural town where math teachers were rare and good ones were nonexistent. I still remember watching Sal Khan's videos on calculus after struggling to get any grip on it from my frustratingly uninterested teacher who was forced into the position after our actual teacher retired. After I saw them I came back with a fire in me because for the first time he exposed me to the beauty of calculus.
This guy is completely wrong about Khan not inspiring students to care. Sometimes all students need is to see what caring looks like to ignite it in themselves. You can feel how much he cares just by watching him because the video is the product of all that caring, and he does it for millions of people.
But thank you to this blog author for being brave enough to call out Khan's failures, I am sure it'll help education much more than Khan did.
I don't have a problem with Khan's site existing, but it's disappointing that often answers to requests for learning materials/ideas begin and end with Khan Academy. My personal opinion is that Khan's videos are roughly comparable to an average-quality classroom teacher lecturing about a typical mediocre curriculum.
They have some significant advantages compared to (just) a classroom: (1) They set a quality floor – sometimes a teacher can be really incomprehensible, but Khan's videos are consistently okay. (2) They are available from anywhere, without need for special social/technical infrastructure, like enrollment in school or access to a university library. (3) They are self paced, which means they can better accommodate the various interest level, motivation, and speed of different students. (A typical classroom also has some advantages: it gives social setting, a consistent schedule/structure, and human feedback.)
I'm also disappointed though, because it seems like, given production resources, there would be potential to make widely available materials that were much better than average lectures. With significant production effort (a team of subject experts and content creators doing a lot of dedicated work on each topic) I think it would be possible to make something truly great, but Khan's videos fall so far short of my imagination.
