Making presentations (not Powerpoint shows)
The Tomorrow's Professor mailing list sent out YAPPB (yet another PowerPoint bashing) today, but this is one of those I think makes some good constructive points about good presentation (whether for business or teaching or youth group programs, etc.), not just "don't use PowerPoint". (Mailing list items are not posted to the blog for a week or two, but see the link to Kaminski's lecture below if you are looking for this before early- or mid-February 2008).
The one sentence message: Slides are excellent for certain types of visual aids, but they alone are not an effective oral presentation (and too heavy reliance on them, for things they are not suited for, is the road to a bad presentation).
The essay is referenced by Tomorrow's Professor as being from a book by Laurie Richlin, but apparently she borrowed it wholesale (with attribution) from an outlined lecture by Stephen Kaminski. The lecture outline has more detail and more constructive bits of advice, so I recommend reading it and reviewing it from time to time. (Kaminski links to another useful lecture of his, "Some Tips for Using Visual Aids".
One very nice point about relying too heavily on a single, flat, static visual medium: "Presenters fail to establish ethos, their most powerful appeal."
Ethos is the personal appeal of the speaker. It is classified by Aristotle as an "artistic proof" that the speaker fashions in his presentation. It involves both verbal and nonverbal elements of the message and must be carefully managed for a presentation to succeed. With PowerPoint™, however, many of the elements that establish ethos are blunted or negated. Speakers don't look at the audience and the audience doesn't look at the speaker. The subtle nonverbal cues are lost such as eye contact, posture, etc. Presentations tend to be read off the slide or handouts, flattening delivery.
Constructive advice: use multiple aides to demonstrate and illustrate: people, objects, models, figurative representations, maps, charts and graphs, spreadsheets, web pages, animations...
