Plurilingual approaches to pre-service teacher education hold promise for critical engagement with linguistic, cultural, and racial diversity in equity-supportive ways. Employing critical action research, we as teacher educators implemented an equity-oriented plurilingual approach across three literacy methods courses for pre-service elementary teachers at one Canadian university. Using case study methods and a poststructuralist theory of identity, this paper examines implications of the equity-oriented plurilingual approach for the evolving teacher identities and beliefs about plurilingual pedagogical possibilities of two pre-service teachers: one Chinese Canadian and one White Canadian. Findings from an analysis of field notes, teacher education artefacts, and interview transcripts demonstrate that pre-service teachers' linguistic and racial backgrounds shaped their learning and identity trajectories vis-à-vis plurilingualism, and that critical personal reflection and practicum experiences were key mediators of participants' orientations towards plurilingual pedagogies. Plurilingualism, in concert with multiliteracies, supported a Chinese Canadian pre-service teacher to develop a resource orientation to her own plurilingualism and racialized identity, while challenging a White English-dominant pre-service teacher to confront power inequities and her English-speaker privilege. Implications centre on the importance of greater critical engagement with systemic issues of race and Anglonormativity and the need for more systematic integration of equity-oriented plurilingual approaches throughout teacher education programs.
