This February I will be presenting at a state technology conference in Virginia. I've been to enough presentations to know what I don't like, and being the perfectionist that I am, I want to make sure I don't make those suffer who attend. I get these pictures in my mind of a bobbing head up front that sounds like Charlie Brown's teacher (the trumpet sound). What advice do you have for keeping your participants actively engaged? What did you do that was successful? Did you do anything that made you say, "I'll never do THAT again?" When you got your evaluations returned to you, did you learn something that can be shared with other presenters? Thanks ahead of time!
