Reframing translanguaging practices to shift mathematics teachers' language ideologies

While dominant narratives about multilingual students position them as deficient, translanguaging theory has played a critical role in making space for the languaging practices of multilingual students in education. However, we know little about how to best support mathematics teachers' learning about translanguaging. Working with a group of accomplished mathematics teachers taking part in professional development on culturally sustaining pedagogies, in this paper we use frame analysis to examine the ways language ideologies shape teacher sensemaking about translanguaging. We then investigate affordances of classroom video for reframing teachers' conceptualizations of language. We find that although teachers initially framed students' language as a barrier to their success, with the introduction of video clips from mathematics classrooms, teachers began to frame students' language as a tool for productive disciplinary engagement. These findings suggest that video may serve as a valuable resource for reframing teachers' conceptualizations of students' languaging practices in mathematics classrooms.
