The most recent issue of Reference & User Services Quarterly has an excellent article that is ostensibly about the use of PowerPoint, but is really about good presenting, and by extension, good teaching.

Brier, David J. and Vickery Kaye Lebbin. “Perception and Use of PowerPoint at Library Instruction Conferences.” Reference & User Services Quarterly 48.4 (Summer 2009): 352-61.

The first half of the article documents how librarians use PowerPoint at instruction-related conferences (the conclusion: probably not well). The second half of the article gives recommendations on how to use PowerPoint to create “colleague-centered presentations” – presentations that engage the audience and create a learning environment, rather than just a lecture. The authors’ ideas are applicable not only to professional conferences, but also to in-house and student presentations, as well as instructional settings. This article is really about much more than just PowerPoint and I hope it gets the attention it deserves, given the misleading title. Highly recommended!
