In the last few years, xenophobic rhetoric and policies have sharply increased across the world and is especially apparent in the rise of far right political parties in Europe, the Brexit vote in Great Britain, and the election of Donald Trump in the United States. In these times, teachers have a responsibility to stand for values of inclusion and justice and be a voice of reason among the growing angst and fear-based policy decisions. This article explores the theoretical rationale for taking this position in the classroom in relation to the purpose of education, promoting the good of all students, and creating a classroom environment based on critical thinking and a strong analysis of current cultural and political trends. The article then looks at practical ways teachers can deconstruct this xenophobia in the classroom through instructional practices, creating a welcoming classroom environment, and curricular choices. Although these concepts are applicable in all subject areas, they are of special relevance to social studies teachers.
