2. My Flipped Classroom:
Learning Cycle:
(Demo?)
Video Flip/Canvas Quiz
Work Time:
Problems in small groups (Quadpods)
Conceptual questions
Mini Demos
Messing around with stuff
Interactive Lecture Demos
Practice test/They grade it
Test Test/Retakes
My website:
Angular Mechanics: https://sites.google.com/a/ttsd.k12.or.us/tuhsphysics/home/htp-ib-physics/rotational-mechanics?authuser=0
Naming Convention
Former Students
Myself
Reflection:
Not perfect - I had a good routine before - but the flipped classroom is mostly better/last years scores
Sometimes the best thing for me to do is to shut up and let them work/(I miss being the center of attention : -)
3. The Controversy Surrounding Conservation of Angular Momentum:
Hey John - I actually did a little experiment - to test these two models. Yours, that the mass on the string does not increase its velocity when it is pulled in, and the model of conservation of angular momentum, that the velocity of the mass times its radius remains constant. (i.e. if you pull it halfway in, the velocity will double) You can read the paper I wrote here:

You can access the videos I made and the spreadsheet I used here:
