Dilys -- I loved this presentation. I thought the way you presented the text/images/videos was very easy to follow (for a difficult set of ideas, no less). I really enjoyed the videos. I thought your use of animations in the PPT was fabulous -- it enhanced, and did not detract -- from the material being presented. The information you presented was clear and concise (again, for a difficult set of ideas) and not boring. Your use of the "thumbs up" supporting images was really cool. The presentation was easy to navigate and to follow.
I think your quizzes were great, and I think it was good that you had people go back to retake an incorrect answer (I did not do this on my StAIR, and think that I should have done so, after watching yours). I think this crystallized the material that you presented. I also liked the way you chunked the material so that it was not so overwhelming -- the pacing of the quizzes spaced throughout the material was perfect, in my opinion.
I thnk this is a high quality presentation, and one you could use in a real classroom.
