University science education has been undergoing great amount of change since the commercialization of the Internet a decade ago. Mobile technologies in science education can encompass more than the proximal teaching and learning environment. Podcasting, for example, allows audio content from user-selected feeds to be automatically downloaded to one's computer as it becomes available online, and then later transferred to a portable player for the user's consumption at a convenient time and place. Enjoying a phenomenal growth in mainstream society, podcasting is asynchronous and could be provided at a distance from a classroom. This paper reports a case study from the University of British Columbia that implemented podcasting for physics content. It presents the rationale for, technical details, and step-by-step guide to creating podcasts in the sciences.
