I'm not surprised at all. My observation has been that teachers - even ones who are brilliantly good as teachers - are abysmal PowerPoint users. Every one I've seen has made the same kind of mistakes: - Way too many slides for the time available - Numerous slides that with both paragraphs of text and elaborate diagrams - Slides that cannot be read at all by the audience because everything is too small - Reading verbatim from slides in the presentation - A firehouse of information that is impossible to remember or even follow - Zero narrative flow, no sense of what are key points [edit: fix formatting]
