5 Tips for a Great PowerPoint Presentation
Give them a break.
According to a recent research paper from University of Tennessee, the average adult attention span for a presentation is just 20 minutes. It’s always best to keep your presentations short and to the point, but if you must exceed the recommended 20 minutes, try giving your audience a moment to relax. “You can prolong attention spans by periodically giving your audience a rest,” the study says. “This can be done by telling a story, giving a demo, or doing something else that gives the brain a break.” Steve Jobs offers a perfect example: during a recent presentation, Jobs pulled up a blank slide—not as a mistake—but as a way for people to relax and maintain their focus.
