Effects of applying multimedia design principles in PowerPoint lecture redesign

ObjectiveTo measure the effect of a multimedia design principle adherent PowerPoint presentation on test item performance, student satisfaction, student confidence in potential exam performance, and classroom dynamics.DesignTwo versions of an identical lecture were presented in different formats over subsequent years (2011, 2012, and 2013). One with traditional PowerPoint slides and the other redesigned to comply with multimedia design principles. Student scores on identical exam items were compared and a voluntary student survey was used to evaluate the activity.AssessmentStudents performed statistically better on identical exam items, were very satisfied (mean = 7.4 of 10) with the redesigned PowerPoint format, confident in their potential exam performance, and a majority (66%) wanted to see pictures and narration more often.ConclusionStudents may retain information better when presented in a multimedia design adherent format. Student reaction was positive and indicates that students may prefer this method to traditional PowerPoint slides.
