People often justify history's place in the curriculum by its relationship to citizenship, yet there is little research to help educators picture how people use historical knowledge for civic purposes. This expert-novice study used the think-aloud method to examine how eight political scientists and eight high school students employed historical knowledge to reason about a political issue. Findings indicated that detailed historical narrative played an important role for experts' reasoning, and the experts used narrative to frame the issue, support their positions, and evaluate historical claims. Participating students used narrative as well, but their narratives were lacking in detail. They never used history to frame the problem, contextualize documents, or to support their positions, and they rarely used narrative to evaluate claims. These differences in how experts and novices use history to make sense of the present have implications for history instruction and research in history and civic education.
