This edited volume brings together 10 cutting-edge empirical studies on the realities of English language learning, teaching and testing in a wide range of global contexts where English is an additional language. It covers three themes: learners’ development of interactional competence, the organization of teaching and testing practices, and sociocultural and ideological forces that may impact classroom interaction. With a decided focus on English-as-a-Foreign-Language contexts, the studies involve varied learner populations, from children to young adults to adults, in different learning environments around the world. The insights gained will be of interest to EFL professionals, as well as teacher trainers, policymakers and researchers.
