This article examines the inclusion of a culturally relevant curricular practice of social identity papers within teacher education in the USA that incorporates the transnational lifeworlds of teachers. Using tenets of feminist interdisciplinary frameworks, we highlight how this curricular practice allows teachers and teacher candidates in urban and rural contexts to examine transnational lifeworlds and their influence on culturally relevant practices in relation to notions of oppression and privilege. We focus on linguistic border crossings and both/and perspectives of teacher's social identities. More research is needed to better understand the construction of teacher's social identities within and across transnational lifeworlds and the ways it impacts their practices and student's academic and social achievement.
