Most history courses follow a relatively simple formula: take a geographic space X, select a time span from A to B, add topics, and you’ve got yourself a course. It varies, of course, but works for both introductory courses, where you might survey the political, social, and cultural development of the people living in a geographic area, to upper-level courses with topical focuses. As a field whose primary concern is change over time, that formula makes sense. That consistency also means that students expect it from their high school and college history courses. And how else would you organize a history course?
I found out last semester.
