Abstract
<jats:title>Abstract</jats:title> <jats:p>Identity has emerged as an important construct in applied linguistics research, including investigations of additional language learning and teaching, multilingualism, migration and globalization, and several other areas of study examining the role of language in investigating and solving real‐world problems. Two complementary theorizations of identity—Norton's poststructuralist framework and Bucholtz and Hall's sociocultural framework—have continued to inform investigations of the ways in which language practices shape and are shaped by identity construction in language educational settings. This entry elaborates on poststructuralist and social constructionist theorizations of identity and presents examples of recent empirical studies in language teaching and learning contexts that reflect the mutually constitutive nature of language and identity. The chapter ends with a brief discussion of future directions for researching identity in language education.</jats:p>
