other side of the podium

As you can probably tell, this post is about teaching. I'm currently teaching a 300-level lab class (Developmental Biology Lab), which is full of seniors about to graduate. It's my first time actually teaching, as opposed to leading study groups or doing one-on-one tutoring sessions.

I led study groups for intro physics for a little over two years, and I still remember the first study group I ever had. First off, it was a class full of engineers, and there were still parts of the class I didn't fully understand (ahem, like the first few chapters?!). I was shaky on topics at the beginning of the course and had a better understanding of what came after, so things smoothed out as the semester wore on. As a result, I ended up learning quite a bit about the subject as well, and study group dynamics worked themselves out after a semester or two.

The biggest problem with actual teaching is the understanding (and acceptance) of the fact that not everyone who is in the class wants to be there. I never had a problem with it in the past, since study groups and tutoring sessions were made of people who wanted my help, not because they needed to get a tutor in order to fulfill some sort of requirement for their major. My own rationalization for this was that I was teaching an upper-level class, and that these were seniors who had already completed all the reqs for their degree.

The other difference is the authority problem. The class was off to a bumpy start, because I think no matter how prepared I thought I was, I still got a bit nervous standing there and talking to 22 people who I've never seen before. 22 kids. That's more than twice the size of my average study group.
I'm also physically the smallest in the class, which has the potential to compound the authority problem. But I think I have that problem under control with pop quizzes, lots of clarification, and randomly picking on people to answer questions.
I think I've also gotten some sort of reputation for being a tough grader as well as a walking advertisement for my advisor's lab. Just wait until they see the metamorphosis experiment in this course. :-)

Finally, teaching a class makes me realize that I most likely took my undergrad profs for granted. Students often complain about a badly worded test question, or just an overall impossible exam. But just as exams are hard to take, they're also pretty hard to write. After a particularly disruptive class one week, I went home and started putting together a pop quiz. Brainstorming a topic and a question for the quiz took me a long time. I wanted to cover "big picture" concepts and apply it to an organism that they never learned about, but at the same time, I didn't want them to be completely stumped (ok, I did; they made me angry!) and miss the concept at hand. The bottom line was that I did NOT want to write some multiple choice question that they're just gonna forget after they hand it in...but it was quite tempting to do so and get the writing over with.

All in all, teaching is enjoyable. The department requires two terms of teaching, but I wonder if my advisor will let me do more...

That being said, being a GSI isn't difficult.. provided that I continue to come prepared to class and refuse to take any shit from students twice my size.
