Math teachers critiquing Khan Academy math videos
This is a great point, and it’s the same one that we’re trying to make with Lauren’s paper at ICER 2012. Instructional design matters! Educational psychologists do know how to make learning better. Lauren’s well-designed video results in better learning (fewer errors, more retention, and signs of transfer). To Khan’s credit, he is updating his videos in response to these critiques. Better yet, he might hire an instructional designer to do the critiques in-house.
The errors highlight a blind spot that plagues many Khan Academy lectures: Khan is both brilliant and talented, but he doesn’t know much about pedagogy, the science of teaching information effectively.
The video filtered up through the ranks of ed bloggers to Justin Reich’s blog in the trade publication Ed Week, and within five days of going up on YouTube reached Salman Khan. To his credit, Khan took down his original video and released two new, better lectures in its place within two days. He also sent a comment to Reich saying that he appreciates the feedback.
