"I think so I am."

I really enjoy discussing the questions on tests with students. Classes 310, 313, and 314, they all participate actively in the discussion. I could have saved more time if only I talk, giving one-way explanation. However, I believe in the power of thinking. As Descartes said, "I think so I am." In fact, we often forget what we are told. We remember what we try hard to figure out.
