From Diversifying Economic Quality: A Wiki for Instructors and Departments
Bartsch & Cobern, 2003. This study, titled "Effectiveness of PowerPoint Presentations in Lectures," examined that differences in preference, perceived learning and test performance between class units taught using transparencies, a basic powerpoint presentation and an advanced powerpoint presentation including images and sounds. Students were surveyed directly after each lecture and at the end of the course and performance was measured using class averages on assessments administered for each unit. The study found no significant difference in preference between the three modes of presentation. However, students believed they learned more from both types of powerpoint presentations than from transparencies. It was found that students performed about 10% worse on the units taught using the advanced powerpoint presentation that included images and sounds.
