I like the idea of videotaping myself during class; I'm sure I'd see annoying tics that would be distracting to my students. I've had several instructors who repeated certain words or phrases (I hope they were inaware of it) that I found distracting. I remember one time, out of sheer boredom, I started counting how many times a particular instructor repeated the word "again" during a lecture. I quit after about a minute and a half because I was already up to EIGHTY!! Another instructor never "said" anything, he always "indicated," and in my most recent administrator's opinion, everything she likes is "amazing." Makes me think of Valley-Girl speak - the mouth is flapping but the brain is not connected. As instructors, we should hold ourselves to a higher standard of speaking and writing so our students may hear and see how an educated person communicates, and we might provide a model for them to emulate.
