first day of class. no pressure. you’ve got two seconds.
Classes started today. Somehow I still have first-day jitters. The problem could be that I am overly cognizant of the importance of first impressions, you know, those first two (!) seconds of teaching. I think the received wisdom is that one should aggressively wave one’s hands around (as modeled by Dwight) and, well, look good. That finding of course was popularized by Gladwell. Here’s Ambady’s original JPSP (pdf) piece on “predicting teacher evaluations from thin slices of non-verbal behavior and physical attractiveness.” Here are the cliff notes on the six second teacher evaluation.
And, how much do students remember after the semester? Research says, not a ton. So there’s the five minute approach.
