2. My Flipped Classroom:

Learning Cycle:

(Demo?)
Video Flip/Canvas Quiz
Warmup/Seating Chart/2 Questions
Work Time:
1. 1. Problems in small groups (Quadpods)
  2. Conceptual questions
  3. Mini Demos
  4. Messing around with stuff
  5. 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:

Christopher Murray

3 years ago

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:
