Also the OECD have released a report on e-learning. There is a useful summary of the report online.
But none of this helps me work out exactly what audio or video encoding to use for a podcast, so that an Apple iPod and other devices can actually play it. What I had in mind was the "HOW TO make Enhanced Podcasts (images, links and more with audio)" from O'Reilly They also provide a sample enhanced podcast.
Some of the items on Podcasting at US universities:
The University of Missouri has a useful whitepaper on how podcasting and vogcasting (video) work and some discussion on educational use.
Duke University held a Podcasting Symposium, September 27 - 28, 2005, the sessions of which are available as podcasts
University of Wisconsin have a useful page on "teaching & learning with podcasting" :
Avoid overly complex and dense content material that includes lots of facts and figures. ...They then go on to the details of how to create & deliver podcasts.
Recordings of classroom lectures may not be the best use of podcasting. ...
Narrow the focus of a podcast ...
# Plan what you will say ...They go to mention Audacity, free, open source audio software, which I have used and works well.
# Record audio ...
But the only place mentioned to publish the podcast is the Apple iTunes Store. Stanford University seem to have gone a long way down this path, creating "Stanford on iTunes":
* Download faculty lectures, interviews, music and sports.The only way to access this content seems to be to sign up to iTunes. Why the university doesn't make the content available on its own web site isn't made clear. Perhaps Standford fears its web servers will be overloaded or is it that you can only load content onto an iPod via iTunes?
* Play audio on your iPod, Mac or PC, or burn a CD.
* Stay Connected anytime anywhere.
* Experience Stanford on iTunes today and continue learning with Stanford.
