The volume explores how globalization creates new identity options for language learners, and it considers what implications this has for language learning, teaching, and use. The chapters investigate how transnationlism, intercultural contact zones, and globalized media shape learners' identities as they learn and use additional languages. Through case studies, narrative analysis, and ethnography, the volume examines identity construction among learners of English, French, Japanese, and Swahili in Canada, England, France, Hong Kong, Tanzania, and the United States.
