This is a very good article, and certainly worth the read. I normally don’t quote this much from a source, but this part really stood out to me:
One of education historian Diane Ravitch’s oft-uttered complaints is that we now have a bunch of billionaires like Gates dictating education policy and education reform, without ever having been classroom teachers themselves (or without having attended public school).
But the skepticism about Khan Academy isn’t just a matter of wealth or credentials of Khan or his backers. It’s a matter of pedagogy. No doubt, Khan has done something incredible by creating thousands of videos, distributing them online for free, and now designing an analytics dashboard for people to monitor and guide students’ movements through the Khan Academy material. And no doubt, lots of people say they’ve learned a lot by watching the videos. The ability pause, rewind, and replay is often cited as the difference between “getting” the subject matter through classroom instruction and “getting it” via Khan Academy’s lecture-demonstrations.
But that’s the crux of the problem right there: lecture-demonstrations. Although there’s a tech component here that makes this appear innovative, that’s really a matter of form, not content, that’s new. There’s actually very little in one of the videos that distinguishes Khan from “traditional” teaching. A teacher talks. Students listen. And that’s “learning.” Repeat over and over again (Pause, rewind, replay in this case). And that’s “drilling.”
And while Khan Academy and his students may tout mastery, some educators aren’t so sure. They point to studies that find while students receive these sorts of videos positively, they are actually learning very little or learning very superficially. Physics teacher Frank Noschese, for example, contrasts the video of Khan’s explanation of force with a video documenting his students’ exploration of force through hands-on experimentation.
