According to the authors, a social justice curriculum positively influences all students. Social justice, critical pedagogy, and culturally relevant teaching are becoming essential as more and more language educators teach in increasingly diverse world language classrooms. This new publication supports in-service and pre-service teachers in recognizing their students' diverse backgrounds while also supporting students' ability to think critically about the world around them. Questioning mainstream approaches to language and culture learning is vital. An emphasis on social justice is, in part, a way to expand the definition and scope of language education, leading to further innovation in the profession.
