Before tenure, one should never re-prep an entire class. But, of course, I did. I've taught an environmental anthropology class twice before, but was never happy with it. I tried a couple different textbooks and readers, and nothing worked for me. They didn't cover the topics I wanted to cover with the perspectives I wanted to include.
So, I've totally re-done the class, using journal articles instead of a textbook, and focusing on those topics I find most interesting. Half the class is dedicated to archaeology, mostly landscape impacts of prehistoric human societies. That portion of the class is divided up into "types" of societies (hunter/gatherers, subsistence agriculturalists, states). The second half of the class is human ecology, specifically sections on disease, diet, and reproduction.
I think it will be a lot of fun! If anyone wants to share resources (syllabi, reading lists, etc.), I'm always happy to do so.
