atw: Re: More on presentations

Hi Craig,

I assume that you want presentations to be for information transfer, 
rather than merely showing off.

When I first did my teacher training and learned about Overhead 
Transparencies [OHT] - the forerunner to PowerlessPointing - the 
research we saw suggested that the OHT should only be used for 
headings - and even only hints of those - a sort of public form of 
palmed cue cards. The idea was that what you 'did' in front of 
and with the 'learners' should be more interesting, nay unexpected, 
to make it more likely to stick.

To rely on people's remembering what they read - a passive 
exercise - is very wasteful; something like about 7%, on average, 
sticks. But when people use more senses - talking, listening, 
conversing, debating, writing, and other whole bodily 
involvement, including emotional involvement - there was a higher 
stickiness.

To even start considering that an OHT, however contrived, is a 
means of transferring information, is a big mistake. My aim is about 
10 words per slide, max. But, I'm more likely to have pix and 
graphs on slides, and if I want people to remember something, I'll 
have incomplete handouts that can only be completed from the 
learners' own activities.

Brian.
