[WS:] This certainly rings the bell. I was taught how to do research and write research papers, nut not how to teach. This was to be acquired by osmosis, I guess. OTOH, they did not teach grant writing either - a skill that is now crucial for obtaining academic employment.
While we are at teaching teaching - there was a lot of talk about it among grad student in my grad school - perhaps because most of them worked as instructors or TAs of one sort or another. In other words, since the subject was not formally taught, people tried to teach themselves by sharing experiences. The impression that I got from these conversations was that one cannot just teach - one has to entertain the students. This idea was lost on non-US TAs, especially Asians, who were good at math and science but not so good at entertaining, and there were some serious cultural differences in that respect. They had terrible time.
So while I agree that pedagogy should be a required course in all graduate programs, I am also aware of its limits while dealing with a bunch of brats who believe that when they pay the top dollar for university admission, it better be entertaining. Based on casual observations from many years ago I think that community colleges are much better in that respect than 4 year universities.
