This paper presents a case study of a yearlong research-based peace education program at one urban K-8 private Catholic school situated in a community plagued by structural violence in an enclave of a large Midwestern city. To frame the analysis, the author employs concepts central to culturally responsive pedagogy (including cultural competence, funds of knowledge, reshaping the curriculum, and activism) in order to highlight some of the unique challenges involved in implementing a peace education program in a diverse, urban environment.
