4. We started with a few questions What is video podcasting? When is video podcasting a helpful addition to a live or online course? What educational institutions are currently making use of video podcasting for instruction? How does one create and distribute video podcast content?

5. Video Podcasting A podcast is an audio or video file placed on the Web for individuals to subscribe and listen to primarily on MP3 players such as the Apple iPod. The term podcast like that of radio or video can refer to either the content or the method of delivery. Video podcasts contain some combination of audio and/or visual information (still images, animation, or video). The digerati call it vodcasting.

6. Video Podcasting for Instruction It may allow students an opportunity to receive supplemental multimodal presentation, which is generally accepted as beneficial, particularly in the apprehension of complex concepts (Tuovinen, 2000). Vodcasting presents interesting opportunities for design and research in that vodcast productions may be accomplished with a minimal budget and moderate technological expertise.

7. Institutions Currently Making Use of Video Podcasting Universities such as Duke, Michigan, Purdue, Stanford, and UC Berkeley are making podcasts of course lectures available for their students – especially undergraduates Video podcasting is in its infancy: the vast majority of video podcasts are essentially collections of clips produced originally for television viewing.

8. Creating and distributing video podcast content Podcasts can easily be created on your Macintosh (apple.com, 2006) Yeah, right. (Brown and Green, 2006) We tested the production process by creating two vodcast episodes.

17. Discussion Video podcasting or vodcasting is a medium in its infancy. Vodcast production and distribution requires a number of digital media manipulation skills. Ellis and Cohn (2001) caution that instructional multimedia supplements are intuitively attractive, but their use must be weighed against the cost of production. Vodcasting currently adds glamour to content, but the old programmers rule GIGO still applies.
