an aid, not focal point

Great article with with some fantastic points. PP definitely should be treated as an aid and not the focal point. In fact, I look back at my university career and (still going) and the most enjoyable and informative lectures didn't have a prof with a PP presentation....they were just great speakers. Like all of the technology we've been talking about, we shouldn't let it be bigger than the content. Good pedagogical practices and superior curriculum content should always be the priority.
