Michael Alley of Penn State University talks about giving better presentations and Powerpoints.

Slide design can make a big difference in how much audiences understand your message. Michael Alley, Associate Professor of Engineering Communication at Penn State University and the author of three textbooks, summarizes recent findings in audience-based research and discusses how managers, such as program managers at NSF, can use the assertion-evidence structure for communicating complex concepts. Dr. Alley also talks about the connection between the assertion-evidence structure and the slide style, which is effective for communicating less complex concepts.
