Presentation at the inaugural Conference on Excellence in Teaching and Scholarship (http://www.adelaide.edu.au/professions/education/) The audio is occasionally a little muddy as I wander around away from the recorder. The last 5 minutes is some useful discussion between audience members (including Dr Kaye Bowman) The movie played during the presentation is at http://www.youtube.com/watch?v=dGCJ46vyR9o Accompanying slides available at http://www.slideshare.net/michaelc (About 28 mins)
