Audio Multimedia in the Classroom

Classrooms have traditionally had a strong audio component.  The lecture based class is auditory in nature.  One of the drawbacks of a lecture based class is that it does not intrinsically support differentiated learning.  One of the things that most interest me about audio multimedia use in the classroom is the idea of podcasts made by the teacher for the students.  In A review of Podcasting in Higher Education: Its influence on higher education, McGarr lists three major reasons for using podcast lectures--flexibility, accessibility, and enhancement.  Students can download lectures to their mp3 players and listen when they have time and as often as necessary.  I think that creating podcast as reviews for units would be quite helpful for students.  This idea would be hard to create a lesson plan around as I see it more as supplementary material than part of class.
Another example of using audio technology int he class that piqued my interest was the idea of creating a newscast.  Lever-Duffy and McDonald cite the example of Wendi Telemota in Teaching and Learning with technology.  I have read about other similar examples before.  They are usually done in a history class.  I thought about I could use this idea in science class.  The history of science is often glassed over.  So I decided to have the students do a podcast about Galileo. Imagine how the events of the inquisition played out and report o n it.
