2021-03-04 meeting notes

Warm-up

Discuss and register your thoughts on:

  1. What about the class is working well for you?
  2. What should we consider doing differently?

I am particularly interested in thoughts on how we are using the meeting time. Is the intro / lecture / breakout structure useful? Are there things we should do to make the group interactions better?
