The goal of this course is to explore various issues related to multilingualism through a framework of Critical Applied Linguistics (CALx). We will examine: the relationship between powerful and marginalized languages; the role of multiple languages in constructing and resisting different identities (ethnic, national, transnational); nationalism; postcolonialism; migration; diasporas; interaction between and among languages (variously conceived of as heteroglossia, hybridity, codemixing, translanguaging, etc.); theories and practice of critical pedagogy in multilingual classrooms; and critical approaches to research, especially critical ethnography in multilingual settings. Most of our readings will focus on language in African societies, but students from other departments should feel free to share examples, in class and in writing, from other contexts.
