Wonder why you might want to podcast your lecture? Podcasting Lectures http://www.educause.edu/apps/eq/eqm06/eqm0634.asp is a rich description of a University of Michigan School of Dentistry project as well as an overview of the podcasting phenomenon in higher education.
"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."
I have to confess that I am particularly fond of the instructional design process that the dental school undertook to determine what technology would best meet the needs of the students. :
"Technology is commonly implemented into teaching and learning situations without using instructional design and formative evaluation strategies or involving students. Faculty and administrators (developers) usually make the decisions. Unfortunately, many novel and innovative projects do not succeed or have disappointing results. Using both the formative evaluation strategies ... and the instructional design process ...helped us identify and adjust to unexpected circumstances and develop a successful technical solution to a learning dilemma. Ultimately, use of these strategies provided the critical data required to ensure long-term and ongoing support."
