TITLE: COMPARATIVE ANALYSIS OF THE EFFECTIVENESS OF ORAL VS. PODCASTING REVIEWING TECHNIQUES Podcasts have evolved at a rapid pace. With the creation of podcasting technology and it's increasing prevalence within the educational system a question must be asked; does this technology really aid in the learning process? The purpose of this study was to compare the use of podcasts to traditional delivery of information in classrooms. Four podcasts were created on the topics of asthma, diabetes, seizure disorders, and acute infections, such as head lice, conjunctivitis, scabies, impetigo, herpes simplex I, ringworm, colds, and the flu, to aid students in reviewing for quizzes. Knowledge retained of students using podcasts was compared to the knowledge retained of those using traditional in-class review. A convenience sample of 174 undergraduate students enrolled in seven teacher university health teacher certification classes during the fall semester of 2009 was used. A quasi-experimental pre-test/post-test design was utilized. By conducting t-tests and an ANCOVA the results showed the podcast reviews were as effective as traditional oral in-class reviews of selected health education topics. In this study the main effect for the review method was not significant (F(1,143) = .682, p>.05), with the intervention groups not scoring significantly higher 51.45 (sd= 4.72) than the control group 50.79 (sd= 4.88). This study also revealed that students support the concept of using podcasts as a review tool. All but one student (98.6%) felt that having pictures accompany the audio portion of the review was helpful in retaining the information. When asked if the podcasts were helpful in aiding them to review for the test (68.9%) of the students strongly agreed and (28.4%) agreed with that statement. The majority (68.9%) stated they would use podcasts again as a review tool with (66.2%) having strongly agreed or agreed that they preferred podcast reviews over traditional in-class reviews. Given that podcast reviews were shown to be as effective as traditional review and with the majority of students reporting they would use podcast reviews again in the future more studies there remains a need to focus on podcasting technology and student outcomes.
