Podcasts and Vodcasts (Video Podcasts) have become popular means for sharing educational information via the Internet. In this article, we introduce another method, an Enhanced Podcast, and discuss how to create it on the Macintosh computer. An Enhanced Podcast is a podcast that allows images to be displayed in time with the audio. Also, it permits the imbedding of URL links and the addition of chapter markers to the audio file. These robust features allow the user to visit websites while the presentation is still playing, and to skip to predetermined spots within the presentation. Enhanced Podcasts may also be created in the Windows OS using programs such as Web Podderator.

To create and subscribe to an enhanced podcast on a Mac, here are the minimum requirements: Macintosh Operating System: Mac OSX 10.5.2 or later; GarageBand ’08 (Apple Computer); iTunes 7.6.2 or later (Apple Computer) The following programs and hardware are also recommended, but not required: iWeb (Apple Computer); iPhoto (Apple Computer); Keynote (Apple Computer); .Mac account (Apple Computer); External microphone, preferably with a breath shield (we use Plantronics .Audio 510) We show, step by step, the complete process of recording and distributing an Enhanced Podcast.

An enhanced podcast is created and the step by step process is described in detail. The example enhanced podcast created and a demonstration video of all the steps described are available at web.mac.com/mthapa

The ability to view images and visit URLs while listening to the audio content in an enhanced podcast allows the user to have a richer experience than with a simple podcast. The use of still images rather than video clips means the presentation file size for an enhanced podcast will be smaller than a vodcast’s, allowing quicker upload and download times. Because the presentations can be downloaded to a PDA, learning can truly be mobile. Creating enhanced podcasts is an effective method of distributing both mini and complete lectures.

Dual coding theory tells us multichannel learning (e.g., auditory and visual) is superior to single channel learning, which makes an enhanced podcast an ideal format for dissemination of information.
