I think it would be great to go into the philosophy in a college course. There the students are a bit more mature and more likely to be taking the class because they
want to. I thought you were talking about high school biology, where I don't think it's appropriate, because at that level the distinctions between different courses are normally much more concrete...so bringing up those issues might confuse the (less mature) students into believing that creationism is a science, which I think it quite clearly isn't.
I don't know if it should be required - not all high school students are capable of that kind of depth of thinking - but I definitely think it should be offered. You're a philosophy major? That's so cool!
