This critical case study (Grosvenor & Pataki, 2017; Merriam, 2009) examines how taking up diversity and plurality within in situ literacy and language arts courses in a Bachelor of Education program created a critical discursive space within mainstream teacher education. Data in this research included interviews with teacher candidates and course assignments. Findings suggest that teacher candidates learned to seek and value diverse students' funds of knowledge, grappled with inclusive practices, and developed equity-oriented pedagogy within in situ teacher education coursework. Through this project we contribute to the rising recognition that in situ teacher education through a lens of diversity can generate curriculum drawing from the literacies and lifeworld experiences of all learners (Grant & Agosto, 2008; Moll, 2014).
