In this book H.D. Adamson reviews scholarship in sociolinguistics and second language acquisition, comparing theories of variation in first and second-language speech, with special attention to the psychological underpinnings of variation theory. Interlanguage is what second language learners speak. It contains syntactic, morphological and phonological patterns that are not those of either the first or the second language, and which can be analyzed using the principles and techniques of variation theory. Interlanguage Variation in Theoretical and Pedagogical Perspective: relates the emerging field of variation in second language learners’ speech (interlanguage) to the established field of variation in native speakers’ speech relates the theory of linguistic variation with psycholinguistic models of language processing relates sociolinguistic variation theory to the theory of Cognitive Grammar suggests teaching applications that follow from the theoretical discussion At the forefront of scholarship in the fields of interlanguage and variation theory scholarship, this book is directed to graduate students and researchers in applied English linguistics and second language acquisition, especially those with a background in sociolinguistics.

Dynamic Variation in Second Language Acquisition makes a cutting-edge contribution to knowledge about how second language learners develop their second language. Drawing comprehensively on Processability Theory’s theoretical understanding that individual variation dynamically interacts with ordered stages of language acquisition, the book provides an informative, critical analysis of historical and contemporary debates about the role of variation in linguistic variation, particularly second language variation. Richly illustrated with a forensic year-long study of how eight adolescent learners of English vary in their acquisition of syntax and morphology, this monograph shows that learners vary in their timing of development between two distinct learner types along a continuum and without skipping stages. The book uncovers how learner variation is dynamic and quite (although not entirely) systematic and how this variation contributes to change in the second language. It will be essential reading for researchers, students, and practitioners.

The Routledge Encyclopedia of Second Language Acquisition offers a user-friendly, authoritative survey of terms and constructs that are important to understanding research in second language acquisition (SLA) and its applications. The Encyclopedia is designed for use as a reference tool by students, researchers, teachers and professionals with an interest in SLA. The Encyclopedia has the following features: • 252 alphabetized entries written in an accessible style, including cross references to other related entries in the Encyclopedia and suggestions for further reading • Among these, 9 survey entries that cover the foundational areas of SLA in detail: Development in SLA, Discourse and Pragmatics in SLA, Individual Differences in SLA, Instructed SLA, Language and the Lexicon in SLA, Measuring and Researching SLA, Psycholingustics of SLA, Social and Sociocultural Approaches to SLA, Theoretical Constructs in SLA. • The rest of the entries cover all the major subdisciplines, methodologies and concepts of SLA, from “Accommodation” to the “ZISA project.” Written by an international team of specialists, the Routledge Encyclopedia of Second Language Acquisition is an invaluable resource for students and researchers with an academic interest in SLA.

This state-of-the-art volume offers a comprehensive, accessible, and uniquely interdisciplinary examination of social factors’ role in second language acquisition (SLA) through different theoretical paradigms, methodological traditions, populations, contexts, and language groups. Top scholars from around the world synthesize current and past work, contextualize the central issues, and set the future research agenda on second language variation, including languages studied or taught less commonly. This will be an indispensable resource to scholars and advanced students of SLA, applied linguistics, education, and other fields interested in the social aspects of language learning in research practice and instruction.

This volume brings together empirical research that explores interaction in a wide range of educational settings. It includes work that takes a cognitive, brain-based approach to studying interaction, as well as studies that take a social, contextual perspective. Interaction is defined quite broadly, with many chapters focusing on oral interaction as is typical in the field, while other chapters report work that involves interaction between learners and technology. Several studies describe the linguistic and discourse features of interaction between learners and their interlocutors, but others demonstrate how interaction can serve other purposes, such as to inform placement decisions. The chapters in the book collectively illustrate the diversity of contemporary approaches to interaction research, investigating interactions with different interlocutors ( learner-learner, learner-teacher), in a variety of environments (classrooms, interactive testing environments, conversation groups) and through different modalities (oral and written, face-to-face and technology-mediated).
