3 principles of course philosophy
3 Principles of Course Philosophy

Learning, not competing

Learn by doing, not by listening

Many small bites

Typical Class Day

  • Before class:

    • Reading and check-in problems (30-60 mins)

  • In class

    • Mini-lecture (10-20 mins)

    • Collaborative problem solving in groups of 4 (30-40 mins)

  • After class and before next class

    • Homework (60-90 mins)

  • So class week =

    • 3 hours class time

    • ≤ 7.5 hours out-of-class time
