Advancing the Knowledge Base on Effective Presentation Slide Design: Three Pilot Studies | CU Experts

The cognitive theory of multimedia learning (CTML) describes a set of empirically tested principles that technical and professional communication research largely acknowledges as important to the design of presentation slides. However, presenters often run into difficulties understanding how to apply CTML principles to contexts in which it has not been tested. We present three pilot studies that extend our knowledge of how to apply CTML principles. Pilot study one suggests that CTML principles can be effective for presenting advanced research to expert audiences. Pilot study two highlights the importance of user testing nonessential images added primarily for visual interest, specifically finding that visual organizer images such as Microsoft PowerPoint's SmartArt, can backfire by unintentionally indicating imprecise relationships while adding little in terms of visual interest. Pilot study three suggests that, when needing to present a long quotation, presenters should avoid verbatim reading and consider abridging or paraphrasing the quotation.
