Bad PowerPoint Slides • Characteristics students don’t like about professors’ PowerPoint slides • Too many words on a slide • Clip art • Movement (slide transitions or word animations) • Templates with too many colors
Good PowerPoint Slides • Characteristics students like about professors’ PowerPoint slides • Graphs increase understanding of content • Bulleted lists help them organize ideas • PowerPoint can help to structure lectures • Verbal explanations of pictures/graphs help more than written clarifications
Student Learning • Students learn more when • material is presented in short phrases rather than full paragraphs • the professor talks about the information on the slide rather than having students read it on their own • relevant pictures are used. Irrelevant pictures decrease learning compared to PowerPoint slides with no picture • they take notes (if the professor is not talking). But if the professor is lecturing, note-taking and listening decreased learning • they are given the PowerPoint slides before the class
Working Memory with PowerPoint • How to leverage the working memory with PowerPoint? • by dividing the information between the visual and auditory modality. • Minimize the opportunity for distraction by removing any irrelevant material • Use simple cues to direct learners to important points or content. • Keep information displayed in short chunks that are easily read and comprehended
