Powerpoint bad for brains
“Research at the University of NSW, Sydney, Australia, claims the human brain processes & retains more information if it is digested in either its verbal or written form, but not both at the same time… ‘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 & decreases your ability to understand what is being presented.’”
