摘要：This paper examines undergraduate student perceptions of the learning utility of video podcasts, with particular reference to their understanding of exotic ecosystems. The podcasts were made accessible to students through a virtual learning environment, either on-line or to download to mobile technology. The perceived effectiveness of the technology was assessed by written questionnaire and focus groups. Students watched the podcasts numerous times, largely within a week of lectures and/or during revision. They agreed that the podcasts were effective in supporting learning and teaching on the module, largely by offering a flexible and visual learning experience. The podcasts were also perceived as a useful resource for revision and assessment, providing visual images that stimulated factual recall and highlighted knowledge gaps. The key to improving the student learning experience lies not in altering the podcasts, but in reflexively developing the pedagogic strategies employed by teachers and learners.
