google-presentations Google's online Powerpoint clone is live. Those who regularly receive PPT files filled with images of cute animals will be thrilled. Right…

If you decide to use Google Presentations it's good to keep something in mind which also applies to PowerPoint:

Do not put what you say on the screen

Australian research shows that the brain is limited in what in can process how. If the exact same information comes to us in verbal and written form at the same time, our brain sort of phases out.

It is more difficult to process information if it is coming at you in the written and spoken form at the same time. […]

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. […]

"The use of the PowerPoint presentation has been a disaster," Professor Sweller said. "It should be ditched."

"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."

So, repeat after me: I will not use bullet points to show what I just said.
