The Routledge Handbook of Second Language Acquisition and Individual Differences provides a thorough, in-depth discussion of the theory, research, and pedagogy pertaining to the role individual difference (ID) factors play in second language acquisition (SLA). It goes beyond the traditional repertoire and includes 32 chapters covering a full spectrum of topics on learners’ cognitive, conative, affective, and demographic/sociocultural variation. The volume examines IDs from two perspectives: one is how each ID variable is associated with learning behaviors, processes, and outcomes; the other is how each domain of SLA, such as vocabulary or reading, is affected by clusters of ID variables. The volume also includes a section on the common methods used in ID research, including data elicitation instruments such as surveys, interviews, and psychometric testing, as well as methods of data analysis such as structural equation modeling. The book is a must-read for any second language researcher or applied linguist interested in investigating the effects of IDs on language learning, and for any educator interested in taking account of learners’ individual differences to maximize the effects of second language instruction.

The Routledge Handbook of Second Language Acquisition brings together fifty leading international figures in the field to produce a state-of-the-art overview of Second Language Acquisition. The Handbook covers a wide range of topics related to Second Language Acquisition: language in context, linguistic, psycholinguistic, and neurolinguistic theories and perspectives, skill learning, individual differences, L2 learning settings, and language assessment. All chapters introduce the reader to the topic, outline the core issues, then explore the pedagogical application of research in the area and possible future development.

This Handbook, with 45 chapters written by the world’s leading scholars in second language acquisition (SLA) and language testing, dives into the important interface between SLA and language testing: shared ground where researchers seek to measure second language performance to better understand how people learn their second languages. The Handbook also reviews how to best measure and evaluate the second language (L2) learners’ personal characteristics, backgrounds, and learning contexts to better understand their L2 learning trajectories. Taking a transdisciplinary approach to research, the book builds upon recent theorizing and measurement principles from the fields of applied linguistics, cognitive science, psychology, psycholinguistics, psychometrics, educational measurement, and social psychology. The Handbook is divided into six key sections: (1) Assessment concepts for SLA researchers, (2) Building instruments for SLA research, (3) Measuring individual differences, (4) Measuring language development, (5) Testing specific populations, and (6) Measurement principles for SLA researchers.

The volume is organized into five sections: Methodological and theoretical contributions to the study of learner language using corpora – setting the scene Key aspects in corpus design, annotation, and analysis for SLA Corpora in SLA theory and practice SLA constructs and corpora Future directions This is a ground-breaking collection of essays offering incisive and essential reading for anyone with an interest in second language acquisition, learner corpus research, and applied linguistics.

This Handbook is a comprehensive volume outlining the foremost issues regarding research and teaching of second language speaking, examining such diverse topics as cognitive processing, articulation, knowledge of pragmatics, instruction in sub-components of speaking (e.g., grammar, pronunciation, and vocabulary) and the attrition of the first language. Outstanding academics have contributed chapters to provide an integrated and inclusive perspective on oral language skills. Specialized contexts for speaking are also explored (e.g., English as a Lingua Franca, workplace, and interpreting). The Routledge Handbook of Second Language Acquisition and Speaking will be an indispensable resource for students and scholars in applied linguistics, cognitive psychology, linguistics, and education.

The Routledge Handbook of Chinese Second Language Acquisition is the first reference work of its kind. The handbook contains twenty contributions from leading experts in the field of Chinese SLA, covering a wide range of topics such as social contexts, linguistic perspectives, skill learning, individual differences and learning settings and testing. Each chapter covers historical perspectives, core issues and key findings, research approaches, pedagogical implications, future research direction and additional references. The Routledge Handbook of Chinese Second Language Acquisition is an essential reference for Chinese language teachers and researchers in Chinese applied linguistics and second language acquisition.

The Routledge Handbook of Study Abroad Research and Practice is an authoritative overview of study abroad and immersive context research specifically situated within applied linguistics and Second Language Acquisition (SLA) for graduate students and researchers in these fields. Featuring contributions from established scholars from around the world, this volume provides in-depth coverage of the theoretical approaches and methodologies used in study abroad and applied linguistics research, and examines their practical implications on program implementation. The Handbook is organized around core areas of research and practice: language development and personal growth; study abroad settings; individual differences of learners; and applications concerning the preparation of students, teachers, and administrators for study abroad, the role of study abroad in foreign language curricula, and future directions. This handbook is the ideal resource for graduate students, researchers, and administrators interested in learning more about linguistic and personal development during study abroad.

This unique state-of-the-art volume offers a comprehensive, systematic discussion of second language (L2) writing and L2 learning. Led by experts Rosa Manchón and Charlene Polio, top international scholars synthesize and contextualize the salient theoretical approaches, methodological issues, empirical findings, and emerging themes in the connection between L2 writing and L2 learning, and set the future research agenda to move the field forward. This will be an indispensable resource for scholars and students of second language acquisition (SLA), applied linguistics, education, and composition studies.

The Routledge Handbook of Instructed Second Language Acquisition is the first collection of state-of-the-art papers pertaining to Instructed Second Language Acquisition (ISLA). Written by 45 world-renowned experts, the entries are full-length articles detailing pertinent issues with up-to-date references. Each chapter serves three purposes: (1) provide a review of current literature and discussions of cutting edge issues; (2) share the authors’ understanding of, and approaches to, the issues; and (3) provide direct links between research and practice. In short, based on the chapters in this handbook, ISLA has attained a level of theoretical and methodological maturity that provides a solid foundation for future empirical and pedagogical discovery. This handbook is the ideal resource for researchers, graduate students, upper-level undergraduate students, teachers, and teacher-educators who are interested in second language learning and teaching. .

Introduction to Instructed Second Language Acquisition is the first book to present a cohesive view of the different theoretical and pedagogical perspectives that comprise instructed second language acquisition (ISLA), defined as any type of learning that occurs as a result of the manipulating the process and conditions of second language acquisition. The book begins by considering the effectiveness of ISLA and the differences between ISLA and naturalistic L2 learning. It then goes on to discuss the theoretical, empirical, and pedagogical aspects of such key issues in ISLA as grammar learning; interaction in the classroom; focus on form, function and meaning; vocabulary learning; pronunciation learning; pragmatics learning; learning contexts; and individual differences. This timely and important volume is ideally suited for the graduate level ISLA course, and provides valuable insights for any SLA scholar interested in the processes involved in second language learning in classroom settings.
