There is a clear need for an operational framework that captures the difficulty of implementing culturally relevant pedagogy (CRP) and supports teachers to imagine new forms of pedagogy. In this report, we present the Iceberg of Culturally Relevant Mathematics and Science Pedagogy (CRMSP), a tool, grounded in the tenets of CRP, that delineates practices ranging from the most accessible and easy-to-implement, to the most subversive yet arguably the most significant in terms of their potential to re-characterize the acts of doing and being competent at mathematics and science. We provide examples of CRMSP that re-position marginalize learners in relation to mathematics and science. We discuss the levels in which this tool can serve to disrupt dominant, inequitable systems of instruction and preview ways it can support teachers' efforts to provide meaningful mathematics and science learning experiences for youth.
