I’m much more animated; I use lots of dramatic gestures and exaggerated facial expressions, and modulate my voice much more than I would in conversation. I also roam around quite a bit as I’m lecturing, never staying in one place for long. I find that all of this is necessary to hold people’s attention. The fact that I teach late (6–11) on Friday nights may be a factor. If I don’t put a lot of energy into my delivery, I see their eyes glaze. It’s definitely a conscious strategy, and not at all like my conversational style. It amuses me that my student feedback forms always rave about my “passion” and “enthusiasm”; hell, I’m just trying to keep them awake and focused. These are mostly young adults, with a smattering of older career-changers.
