This article takes up the question of world history teachers' pedagogical content knowledge by reporting on two separate but related projects. In the first, we briefly discuss an empirical investigation one of the authors conducted into the ways that pre- and in-service world history teachers think about, organize, and make meaning of separate and discrete world historical events, first for themselves and then for their students. It demonstrates the value of world history teachers making multiple connections among world historical events from the biggest to the smallest ones to construct dynamic and coherent pictures of the past for themselves and their students. In the second project, we discuss our innovative history lab, a course designed to help undergraduates enrolled in a world history course "see" the pedagogical moves their world history instructors make. We designed this pedagogical history lab to foster future teachers' understandings of the content knowledge needed to teach world history while they are learning world history as students.
