Interesting article that highlights teachers using vodcasting as a tool for extending instruction and working with students in a variety of media. I believe the model could work very well with the BMS iPod Touch project if teachers were interested in creating short videos of lecture that students could acces outside of class.
Mathematics is an easy course to consider. The teacher can model solving a problem, or applying an estimation technique that students could watch, create their own example applying the strategy, and turn in the product to the teacher.
the model produces a nice intersection of consumption of content, with using the tool for creation of content as well.
