After doing a lot of reading about various types of interdisciplinary studies, I came up with a visual model for the four different types of programs that I think are feasible.  I have not seen examples of the last two, but we are doing a trial of Themed Studies this semester at my college.

I plan to write an article and include more details about these, but I’ve been asked to publish the images somewhere.  I have to ask that you respect the copyright on these.  You can link to them, but don’t use them in your own publications and presentations until I have had a chance to publish them.
