You don't even need to teach the controversy. I remember learning about the Platonic model of the solar system in university. It was so that we'd be better prepared to understand the ancient texts we were going to read. At no one point did the professor even suggest that this was a possibility for reality. This topic (in general, I didn't read the syllabus) for instance would make for an excellent Social Science or even Anthropology class and I could see when students of medicine might want to take it as an elective or a part of a social policy/public medicine curriculum.
