Unplug, think, and write
According to Galloway, using PowerPoint to make a great presentation starts with powering down the laptops and writing out an outline on index cards or a legal pad. “People have to shut off their computer and go away as they’re writing their PowerPoint presentation,” he says.
Establish your assertion
Alley says that he starts planning each slide by writing down a single sentence stating the idea he wants the audience to take away. “You have defined what it is you need to support that statement,” he says. “That’s where it starts.” Alley adds that the sentence should only take one or two lines, should consist of only 8–14 words, and should appear in 28-point font when inserted in the final PowerPoint presentation.
Assemble the visual evidence
Let the assertion sentence for each slide guide your decision as to which visuals should accompany it. Use “explanatory images”—not decorative or descriptive images—to support each assertion, says Joanna Garner, assistant professor of psychology at Pennsylvania State University. When describing the context or methods of your research, photos and movies are ideal pieces of evidence; when presenting your results, elements like graphs, tables, or charts (appropriately highlighted to emphasize key points) will do the trick.
Challenge the defaults
When you actually open up PowerPoint, forget about the program’s suggested defaults. Start with a blank slide, say Alley and Galloway. That way, you can insert your assertion sentence at the top of the slide and pull in appropriate images free from the constraints of the program’s preset inclination towards bullet points and subheadings.
