Are college professors taught how to teach?

I am finishing up my four year education to become a teacher and topping it off with 32 weeks of student teaching in the classroom (and library). I have taken tons of classes to learn how to teach students learning all kinds of methods, out of the box strategies, differentiation, classroom management etc. Every college professor I have ever had has used basically the same instructional method; lecture, take notes, take a test, write a paper, with very little variation on that theme. Near as I can tell many college teachers start as teacher assistants in graduate school and go from there with little to no formal education on how to teach students. So now I am wondering are college professors taught how to teach?
