I’m a historian, and I do a fair amount of pedagogical research. But one thing I’m not is a historian of college-level teaching, which makes Jonathan Zimmerman’s recent work, The Amateur Hour: A History of College Teaching in America, such a delight. What follows here isn’t a formal review of the book; rather, it’s a collection of observations that struck me as particularly important or interesting and that may spur readers of The Teaching Professor to explore Zimmerman on their own.
