In a similar vein, there's a really great talk by Eric Mazur, Physics professor at Harvard about peer instruction — https://www.youtube.com/watch?v=WwslBPj8GgI

He goes into why he started exploring the idea at first (students got 5's on their AP physics exams and had strong problem-solving skills — plug-and-chug — but poor conceptual understanding), the many iterations of the approach, and the data he collected on the way (significant increases in open-ended, conceptual problems, including at other schools that adopted the approach). Really fascinating.

I haven't watched the shorter version, but someone edited they key points down to 18 minutes: https://www.youtube.com/watch?v=rvw68sLlfF8
