To respond to the multilingual turn in language education, this volume constitutes a challenge to the traditional, monolingual, and native speakerism paradigm in the field of Teaching English to Speakers of Other Languages (TESOL) through a translanguaging lens. The chapters offer complex global perspectives – with contributions from five continents – to open critical conversations on how to conceptualize and implement translanguaging in teacher education and classrooms of various contexts. The researchers exhibit a shared commitment to transforming TESOL profession that values teachers’ and learners’ full linguistic repertoires. This volume should prove a valuable resource for students, teachers, and researchers interested in English teaching and learning, applied linguistics, second language acquisition, and social justice.
