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 Routledge Handbook of Second Language Acquisition and Pedagogy of Persian offers a detailed overview of the field of Persian second language acquisition and pedagogy. The Handbook discusses its development and captures critical accounts of cutting edge research within the major subfields of Persian second language acquisition and pedagogy, as well as current debates and problems, and goes on to suggest productive lines of future research. The book is divided into the following four parts: I) Theory-driven research on second language acquisition of Persian, II) Language skills in second language acquisition of Persian, III) Classroom research in second language acquisition and pedagogy of Persian, and IV) Social aspects of second language acquisition and pedagogy of Persian. The Routledge Handbook of Second Language Acquisition and Pedagogy of Persian is an essential reference for scholars and students of Persian SLA and pedagogy as well as those researching in related areas.

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. The Routledge Handbook of Second Language Acquisition is an essential resource for all those studying and researching Second Language Acquisition.

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.

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 Second Language Acquisition and Pragmatics is a comprehensive critical survey of the field of L2 pragmatics, collecting a number of chapters that highlight the key theories, methods, pedagogies, and research findings throughout its development over the last four decades. Demonstrating the ways in which pragmatics has long served as a lens through which to examine patterns of L2 development, the volume is divided into six parts which reflect the field’s structure and evolution: • Constructs and units of analysis • Theoretical approaches • Methodological approaches • Pedagogical approaches • Contexts and individual considerations • L2 pragmatics in the global era The handbook has a particular focus on covering not only traditional topics in the field, such as constructs of pragmatic competence (e.g., speech acts, implicature), teaching and assessment, and pragmatics learning in a study abroad program, but also emerging areas of study, including interactional pragmatics, intercultural pragmatics, usage-based approaches, corpus linguistics, and psycholinguistic experimentation. Each chapter introduces the topic and follows with a description of its theoretical underpinnings, an overview of existing literature, appraisal of current practice, concluding with a discussion of future directions for research and key readings. The Routledge Handbook of Second Language Acquisition and Pragmatics is an essential resource for those with an interest in second language acquisition, pragmatics, and language teaching.

This landmark volume provides a broad-based, state-of-the-art overview of current knowledge and research into second language teaching and learning. Fifty-seven chapters are organized in eight thematic sections: *social contexts of second language learning; *research methodologies in second-language learning, acquisition, and teaching; *contributions of applied linguistics to the teaching and learning of second language skills; *second language processes and development; *teaching methods and curricula; *issues in second or foreign language testing and assessment; *identity, culture, and critical pedagogy in second language teaching and learning; and *important considerations in language planning and policies. The Handbook of Research in Second Language Teaching and Learning is intended for researchers, practitioners, graduate students, and faculty in teacher education and applied linguistics programs; teachers; teacher trainers; teacher trainees; curriculum and material developers; and all other professionals in the field of second language teaching and learning.
