This paper focuses on the potential, challenges, and limits of participatory, narrative and multimodal research methods as contributions to decolonising research on understanding student experiences of teaching and learning in higher education. Drawing on Fraser's social justice concepts of participatory parity, redistribution, recognition, and representation, we argue that methodologies and methods for researching students' experiences need to redress power imbalances implicit in many existing approaches. We suggest how participatory methodologies can be combined with narrative inquiry and multimodal methods where students research their own lives and contexts. We critically reflect on an international study based in South Africa with South African and UK partners involving 65 undergraduate students from rural backgrounds who participated as co-researchers over 12 months. We highlight decolonial debates in relation to participatory research, before outlining our methodological approach and interrogating the potential, limitations, and future possibilities of co-researcher methodologies for decolonising student-focused research in higher education.
