title: Is Video Podcast Supplementation as a Learning Aid Beneficial to Dental Students?
abstract: BACKGROUND
  Podcasting has recently emerged as an important information technology tool for health professionals. Podcasts can be viewed online or downloaded to a user computer or a handheld multimedia device like a portable MP3 player, smart phone and tablet device. The principal advantage of the podcast is that the presentation of information need not be linked with any particular time or location. Since students are familiar with newer technology tools and may be using it on a regular basis, video podcast could serve as a convenient tool for students to help remember both conceptual and factual information.
  
  
  OBJECTIVE
  The purpose of this study was to assess the attitude of first year dental students towards video podcast supplementation and to assess the efficacy of video podcast as a teaching aid in comparison to text book reading.
  
  
  METHODS
  First year dental students were recruited for this study. A didactic lecture class was conducted for the students (n=100). The students were then randomly divided into two groups. Students present in group A (n=46) underwent a video podcast session followed by a multiple choice question test. This was followed by student feedback to assess the usefulness of video podcast. Students belonging to group B (n=54) had a study session for 20 minutes followed by the MCQ test. Students then underwent the video podcast session followed by feedback to assess the utility of video podcast. Mann-Whitney U test was applied to compare the difference in the median MCQ score between the two groups.
  
  
  RESULTS
  The findings revealed a significant gain in the median MCQ score in the intervention group (group A) when compared to control group (Group B). In the feedback form, 89% of students agreed that the video podcast might be useful as it would enable them to view slides and hear the lectures repeatedly.
  
  
  CONCLUSIONS
  Students who underwent the video podcast session performed significantly better in the MCQ test compared to students who underwent text book reading alone. This demonstrates an advantage of video podcasts over text book reading. Majority of students accepted the benefits of video podcast supplementation.
