In the past month, I've helped both of my kids make PowerPoint presentations for school. I begged them to do Prezis, but they were happy to do PowerPoints. Which is fine. But if every kid in each of their classes did PowerPoints, that means that the poor teacher had to sit through Lord knows how many of the things over the week of presentations. Now, I don't have much sympathy for the teachers because they assigned the things and no one has ever taught the kids how to create a great PowerPoint presentation. (Actually, my son's was entertaining. He embedded a video from YouTube and ended the whole thing with a Blabberized Thomas Jefferson. But, both of those sites are blocked at his school, so neither worked on the day of the presentation. But that's neither here nor there...) My point is this: PowerPoint is dangerous. It can kill you. It can bore you to death. Below is a great Slideshare that addresses this very topic.
