In this paper we identify, name, and operationalize six borders typically found in school settings that include dual language classrooms: bordered languages, knowledge, content areas, bodies, selves, and teachers. We identify these borders as a point of departure to show an example of how a two-way dual language classroom operated through a form of border-crossing pedagogy that respects children and reveals authentic multilingual learning. We use this example to propose that, if dual language classrooms are to truly respect racially and linguistically marginalized students, educators must engage in a practice of protest and refusal toward curricular and social violence.
