Research has extolled the potential of transmediation in expanding learners' analytical and critical insight. However, this approach requires teachers prepared to employ this multimodal way of knowing. This study examines the impact of transmediation course experiences on pre-service teachers' comprehension of and critical engagement with multicultural children's literature, particularly in relation to multicultural awareness and social justice; their instructional planning; and their intended practice. Findings suggest presenting and supporting transmediation as a critical literacy approach can have a powerful effect on pre-service teachers' understanding of texts, on their sensitivity to diversity issues, and on their beliefs about teaching and learning.
