Eric Mazur / Turning Lectures into Learning

[@gamachissakata2138]

I am grateful in your deed ''Peer Instruction" I have practically realized how much it is valuable__my students in Undergraduate Quantum Mechanics and I need to go through further

i am interested with your kind explanations include how you guide students to have peer discussions, and that also I have did to my students there in indonesia. i think this is very really involved strong physical for helping them stimulated an ex trim activities because i had it full started in morning to afternoon meeting in the class. thank you after i listening a way you had going with so i can understood every thing the point,

This was fascinating. However, at around 1:11, he asks the question "Who was John the Baptist?" and indicates that it was the second person on the right. However, John the Baptist was 6 months older than the baby Jesus, so it could not be the adult second person from the right. So, the question is, how does this method of teaching perpetuate misconceptions, by creating securing arguments within a group for the wrong answer? Even if there is a teacher-led discussion after the peer discussion, the incorrect peer discussion may reinforce the misconception in a stronger manner than the correction. Has there been any research on that?

Excellent presentation by Prof. Mazur. I am a Ph. D. Software Engineering Professor. I am glad that I am doing some of the things he advocates being correct. I need to do other things that his system pioneers. A technical error I am going to point out in thermal expansion explanation should not detract from the greatness of his lecture. Error: At 44 minutes a student asks that when metal cools would metal regain original shape? [My wording may not be exact.]. Prof. Mazur says that it would. Well answer to that question is not so simple. Precise answer is that it would regain shape if deformation was only Elastic. That is why expanded rubber band snaps back to original shape. But if you heat rubber band a bit and expand it, then it may not come back to original diameter. That is because plastic deformation has occurred and a permanent increase in volume has taken place. So here is the correct answer. Metal will snap back to shape if deformation was limited to elastic form. If plastic deformation has taken place then it will not come back to its original shape.
