One of the better teachers I have had at Columbia. I would suggest earth science to anyone who is looking for a a way to fulfill the science sequence requirement. She was very enthusiastic and made it a point to tell the class that she doesn't care about your attendence record, as long as you learn the material.
Workload:
Short (1-3 question) weekly quizzes, 2 or 3 midterms, and a final. One field trip and a report as well.
