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). Most American high school and college students would find it difficult to giv…
Sal, The only thing novel about Khan Academy is accessibility. Its the same old teacher-centered lectures we've endured for the past hundred years, with a somewhat more charismatic instructor. Most of the criticism I've seen of your work isn't "pseudo-intellectual babble," its merely pointing out what I've stated above, and that it isn't in line with what research tells us about how students learn. Your challenge for…
The biggest flaw in the "Effectiveness of Science" (EoS) video is that it criticizes khanacademy videos by showing that vastly inferior videos don't work. Khan videos are good because they make it easy to think: there are no distractions, just a blackboard and an intelligent voice "in your head" guiding you through the problem domain. In the EoS video, the failing videos try to teach physics by featuring the face of a talking girl with a guy juggling in the background. He might as well give his subjects a physics book and turn them loose in a sports bar to study while following NCAA basketball. Neither method is a good one for learning physics. What's sad is that the maker of the EoS video is not just some crank on the internet, but apparently a newly minted PhD in education who will likely end up teaching teachers or running a school system and it's obvious that despite his vast "education" this guy has no clue how to recognize good teaching.
