Graduate students as teachers

I disagree with the author of the book "Imposters in the Temple," referred to in the article "Academia on the Whipping Post," Aug. 31, who contended that graduate students should do no teaching. I received my doctorate at a large research university and did considerable teaching in the classroom and in the student laboratory. Both students and professors evaluated me, and I am a better teacher as a result. Just where are the future academics supposed to learn how to teach - in front of empty classrooms? Stephen S.
