One thing I want to point out is something I learned in Dr. Caswell’s class:
When you are presenting a PowerPoint, do not self-deprecate. I repeat: don’t self-deprecate. It never goes over well. I remember one time at Central Carolina Community College, a girl started her presentation by telling a joke about her coffee spilling… then said, “Thank goodness I wore brown today.” And… it just didn’t work. She came off as small. Had she not pointed out the spill, nobody would have really noticed it. Then the classroom just stared at her like “Uh, okay.” And then she said something about her cat.
To make a long story short, it was pretty much like the Titanic. And you know what they said about the Titanic? That it couldn’t sink. Well, guess what? IT DID, and the same applies to that joke you think will help you sail in the presentation.
