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
