If a visitor from another planet dropped in to observe teaching in North America (maybe other places as well), they’d likely conclude that teaching could not occur without PowerPoint slides. And they’re not just in classrooms; they’re part and parcel of all kinds of professional presentations. Without question, they’re superior to the old standbys: overhead projectors and slide carousels. But when something is used this routinely, it often happens without a lot of thinking. For that reason, it may be time to revisit some PowerPoint fundamentals, and I’d like to do that with a few basic questions.
