Actively Learning to Teach


students collaborating on project

Today I had an interesting experience while teaching my biochemistry class. I had students write the Krebs cycle on their digital whiteboards while keeping track of the specific carbons in the cycle intermediates. The point of this exercise was to have students understand how biochemists study metabolic pathways and to practice writing the chemistry of the cycle. To initiate the exercise, I explained the biochemical logic of the first reaction. After that, I let them go because we had already spent a lecture discussing the reactions. This produced a fairly lively classroom with students trying to understand the flow of both carbons and energy through the cycle. While they worked, I walked around commenting here and there as needed or when I saw a misconception arising. Clearly, learning was happening. But the weird thing was . . . I didn’t feel like I was teaching.

With active learning, we often discuss the culture shock that students feel. No longer is it sufficient for students to sit listening as passive consumers of information doled out by their instructor. An active learning class compels students to become actively engaged in applying the material and uncovering the consequences of their newly learned knowledge. But for those of us instructors who never had active learning modeled for us as students, the experience can be just as alien. It can be invigorating, as it was today when my students were working hard to understand the biochemical logic of the reactions. But for me, it also felt like was I wasn’t doing my job. I was reminded of those comments on my end-of-term course evaluations: “Haave didn’t teach us! We had to learn it ourselves!”
