I have to give a 40-minute PowerPoint presentation on Thursday. I have all my notes and stuff, and I'm putting together the presentation now. It does include 5-10 minutes of video.
Most of the PP presentations I've done before have been much shorter--5-10 minutes. I don't want to put people to sleep, and I'm going to be pissed if I see anyone playing around on their phones.
Please share examples of good and bad PPs. What makes PP presentations suck less for you? What makes them suck even more? Is there anything I should absolutely not do?
