Podcasting is a new technology with an evolving definition. The term is generally considered to be derived from combining the words iPod and broadcasting. Podcasting involves making audio and video files available for download on a routine basis via subscription (Levinson, 2005).
Nowadays podcast has been increasingly brought into education. Just like other technologies (e.g. video conference, virtual life, etc), educational institutions have to ensure that such technology is worth funding, either in terms of human resources or infrastructure and equipments; and most importantly, it has to enhance the learning environment.
Also, the University of Michigan (U-M) School of Dentistry was thinking to integrate podcast into their teaching, and then chose to conduct the formative evaluation. Surprisingly, findings reveal that students preferred the mobility of the audio recordings rather than video. The reason for this might be the convenience of the audio files which can be access easily. In other words, it does not need high concentration when reviewing the content. For example, students can listen to their lectures while doing exercise, unlike the video media that they have to focus their attention only on the screen. Another possibility of such preference is that the video files are usually big and, therefore, takes time when downloading or transferring to their personal players.
Despite the fact, students did also choose to download video, particularly in certain subjects. This is because of the nature of lecture’s content as well as lecturers’ didactical approaches. To put it differently, some subjects have/use heavily visual presentation (e.g. charts, graphs, etc.) whereas some are only pure speech.
The results also indicate that the audio recording is easier and do not require lot of resources, and hence feasible for the classroom setting. Nevertheless, there must be more concrete plan for further implementation. In this stance, collaboration among all stakeholders is crucial. Moreover, this also yields for sustainability of the project.
