There's a good place to start training faculty on how to really teach, not just drone, on Presentation Zen (a very cool blog on all things presenter, via Seth Godin). A snip of his quotes from "Ted MD":
Most importantly: for a technical presentation the basics that you discuss in your presentation tips are really important: opening, informal tone, use a remote, work the room, using the blank screen feature, and, of course, Passion, Passion, Passion!!!
Actually, the posts are all really interesting, and well worth a pointer to the presenters you know and love (or, at least, hire).
