Hi Joel,

I'll have to think about strategies for a bit since the US and Canada are different enough that I doubt the ones I'd use would work. basically, if I was going to do it up here, and I just might, I would
  1. give people a specific time/space focus: say, Mosul in 2006;
  2. then get them to compare and contrast three different media outlets coverage of hat area;
  3. then I would get them to look for material actually produced by people on the ground there during that time period.
Ideally, the exercise would be used as a way to get my students to figure out what the bias of each source was. As an academic exercise, it would probably work (it did last summer).
