Powerpoint presentations considered Harmful
Posted in Uncategorized on April 4th, 2007 by BergoAustralia’s SMH is reporting PowerPoint presentations a ‘disaster’
Some points from the research:
Pioneered at the University of NSW, the research shows the human brain processes and retains more information if it is digested in either its verbal or written form, but not both at the same time.
Interesting, considering most powerpoint presentations I’ve seen read their slides.
“It is effective to speak to a diagram, because it presents information in a different form. But it is not effective to speak the same words that are written, because it is putting too much load on the mind and decreases your ability to understand what is being presented.”
I have noticed some corporates, including my own, claiming powerpoint is documentation. I.e. Do you have any documentation?, yes here’s the sales/marketing slidedeck.
I don’t think marketing people get what technical documentation actually is, and vice versa.
For some interesting presentation skills and techniques there is always Presentation Zen , and the way out Dick Hardt presentation at OSCON 2005.
It will be interesting to see how this research is accepted or not. Will it be debunked, confirmed, discredited?
So now even presentation skills to convey information are coming under the spotlight, much like communication skills.
This has many ramifications for Education, which is now all powerpoint (at least in my Masters of Business it was). Come to think of it my undergraduate degree usually had code or maths on overhead projectors, which the lecturer talked about but never read …
