Although primary source work is a major component of undergraduate history degrees in many countries, the topic of how best to support this work has been relatively unexplored. This article addresses the pedagogical support of primary source work by reviewing relevant literature to identify the challenges undergraduates face in interpreting sources, and examining how in two courses carefully articulated course design and supportive teaching activities assisted students to meet these challenges. This fine-grained examination of the courses is framed within a socio-cultural account of learning. The findings show how a skilful drawing of students into the interpretive/discursive practices of source analysis was associated with an epistemological reframing of historical knowledge and dialogical forms of teaching that helped the students to take forward a dialectical engagement with sources. The benefits of an "integrated" approach to source work that fosters students' affective and intellectual engagement with historical interpretive practices are highlighted. (Contains 1 figure.)
