An interesting and critical story about the use of Powerpoint.
Perhaps I am just a bit too “old school”, but in my teaching I have resisted using Powerpoint (or any of the other versions whose names I do not even know). Though, I admit to having given in at conferences where I now routinely use such slides. In my defence I started using Powerpoint at conferences after I found myself consistently addressing audiences that were completely or significantly EFL (English as a foreign language) – a consequence of my extensive activity in Asia. For that sot of audience, Powerpoint seems to be of some assistance (though even there I would be happy to be persuaded otherwise).
While I always had a gut reaction about learning and teaching that relied extensively on technology, and Powerpoint in particular, it is heartening to have my gut feeling somewhat vindicated by this story (and its own internal links).
