A couple of weeks ago I had the pleasure of attending a webcast sponsored by Microsoft's Leadership Forum titled "How to Prevent PowerPoint Overload" presented by Cliff Atkinson from Sociable Media. Cliff is the author of Beyond Bullet Points, Microsoft Press, 2005.
Cliff did a great job of presenting some research data, tips and techniques to make your PPT presentations more effective.
Among the research that he referenced was data from Richard E. Mayer, an educational psychologist and author of Multi-media Learning, that claims that learning retention increases by 69% when extraneous information is removed from the screen and that transferance or the ability to make use of the information increased by 105%. His research also shows that retention increased by 28% when the presenter does not read the information on the slide and that transferance increased by 79%. All the more reason not to read your slides!
Presentation Zen had a blog posting on this topic early last month.
Cliff's premise is that a presentation and presenter should see their role as a storyteller. As a storyteller, Cliff suggests that presenters follow a 3 step process to craft an engaging story:
- Write a script
- Storyboard the script
- Produce the script in an engaging fashion
Cliff used storytelling during this presentation with some excellent metaphors like the eye of a needle, through which the story has to get from the presenter to the audience without overloading short term memory. He suggests that you use your slides with the title summarizing the story, the visual illustrating the story and the notes as your narrative to tell the story. This ties in nicely with Mayer's research on their being two key learning channels - auditory and visual. Cliff suggests that reducing overload between these two channels enhances learning.
