The search for instructional tools that help engage students with the concepts taught in introductory biology courses has led to the untested adoption of many technological solutions. Podcasting can be used as an instructional technology that allows students access to course information at a time and place of the students' choosing. Because students choose when to use podcasts, students should be more receptive to the information. While several cognitive theories support the proposed benefits of podcasting as an instructional tool, to date no studies have examined the effect of podcast use on student performance in a naturalistic, semester-long, class setting. This study examined whether students who used course-related podcasts had a greater understanding of biological concepts as measured by higher percent gain scores on exams, compared to percent gain scores from students who had not used podcasts. Current research in cognitive theory was used when developing the four podcast types for this study: complete audio, complete video, segmented audio, and conversational audio. Students enrolled in a mixed-majors biology course were tracked with a computer program that recorded student podcast subscription, exam responses, and information regarding student study habits and attitudes toward podcasting. Although different podcasting strategies were used, none were found to have had a significant effect on student percent gain scores when compared to a control group. However, student attitude toward podcasting remained very positive and significant findings regarding the study habits of podcast users were reported. Future research in the area of podcast use was recommended.
