Stephen pointed out a good analysis of the Podcast Theory Gap by Susan Smith Nash. She points out the implication of many theories in learning with regard to podcasts as part of online courses. But one point at the beginning of the article puzzles me:
Although instructional designers do not often like to mention this, the fact is, it is the rare learner who will sit at a computer and willingly watch a 20 or 30-minute presentation. However, the same learners are happy to listen to an audio file (podcast or book on tape).
I can only speak to my experience, but I would willingly watch a well designed 20 or 30 minute presentation. Lawrence Lessig’s presentation on Free Culture from OSCON 2002 is one of the most coherent arguments for rational limitations on intellectual property. There is also an audio only (MP3) version of the presentation, but the full multimedia (slides and audio) experience is not to be missed.
But I am also quick to admit that I am not most learners. Indeed, I didn’t think of watching and listening to Lessig’s presentation as learning, at least not in a formal sense. It was just something that I found interesting and more worthy of my time than an episode of Seinfeld. I think that Susan is meaning learners in a formal, course-based context. Would they be willing listeners to the an audio track that was narrating some powerpoint presentation? It doesn’t sound any more onerous than attending a lecture, so I assume that they would. In fact, in an online course a podcast might be the only time a student would actually hear the instructor’s voice, and the effect of this might be to reduce the affective distance between the students and the instructor. The value of the podcast might not be strictly in the content it contains, but in the sense of connection the listener has for the speaker.
A quick google search for online courses that use podcasts yielded no results, which is not surprising considering that podcasting is barely a year old yet (the first entry for podcast in wikipedia is dated from August 4, 2005). I’m sure that there will be at least a few teachers and instructors integrating podcasts into their online courses this coming year, and then we’ll have some actual student experiences to compare to theory.
