How to be a good TA over at Built on Facts.
Disclaimer: I never did recitations as a TA in grad school, though I did tutor students (for a whopping 8 bucks an hour). I had just gotten out of the navy, where I had logged somewhere around 2500-3000 classroom teaching hours, so it’s not like I needed to acquire any lecturing skills. I did labs, which involved only a few minutes of lecture time, and then a lot of Q&A. I didn’t want the repetition of six or so recitation sections, and I knew (from being a student and having done undergraduate TA-ing as well) that labs didn’t always go the full three hours. So, does any of my advice or criticism really apply?
But what do my students say in their confidential evaluations? My scores are always pretty high, but the single most common good thing they have to say about me is this:
He speaks English.
Yeah, I got that a lot, too, as a TA. Which just goes to point out that student evaluations more-or-less follow Sturgeon’s law. 90% of them are crap. The student’s judgments are not always objective, nor do they usually give constructive feedback. They can like or dislike you, and give evaluations accordingly, based on criteria other than teaching quality. And that’s what many of them are — statements of whether the student like you, rather than your effectiveness. I remember one teaching evaluation in which the student complained about how I blocked the board some of the time and he couldn’t read it. He sat near the front in the left-hand row (as viewed from the back of the classroom). I’m right-handed and bigger than a breadbox. It’s physically impossible for me to not block part of the board, and the part I will block will affect those on that side of the class a little more. Basic geometry, really. But it didn’t stop the student from whining about it mentioning it.
