This article discusses the exploratory stage of a research project addressing concerns of preservice M.Ed students in France regarding issues related to diversity by examining how an intercultural course can contribute to the shaping of their understanding of diversity. The criteria retained to analyse how the course can potentially participate in this shaping is discussed and illustrated with a sample Personal Experience Description. This PED shows how the course can give students the theoretical background needed to frame past experiences. The promising preliminary results will enrich the main phase of this project.
