In a similar vein, there&#x27;s a really great talk by Eric Mazur, Physics professor at Harvard about peer instruction — <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=WwslBPj8GgI" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=WwslBPj8GgI</a><p>He goes into why he started exploring the idea at first (students got 5&#x27;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.<p>I haven&#x27;t watched the shorter version, but someone edited they key points down to 18 minutes: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=rvw68sLlfF8" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=rvw68sLlfF8</a>
