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.

Methods in current instructed second language acquisition research range from laboratory experiments to ethnography using non-obtrusive participant observation, from cross-sectional designs to longitudinal case studies. Many different types of data serve as the basis for analysis, including reaction times measurements, global test scores, paper and pencil measures, introspective comments, grammaticality judgements, as well as textual data (elicited or naturalistic, oral or written, relating to comprehension or production). Some studies rely on extensive quantification of data, while others may favour a more qualitative and hermeneutic analytic approach. Many of these issues and methods are exemplified by the contributions to this volume. Data-based studies included here deal with the acquisition of specific linguistic phenomena (e.g. verb and noun morphology, lexicon, clause structures) in a range of target languages (e.g. English, French, German, Russian) from a variety of settings involving different instructional approaches (e.g. traditional foreign language classes, immersion classes, intensive ESL classes, content and language integrated language classes). Collectively, the chapters in this book illustrate the productivity and diversity of current research on instructed second language acquisition. As such they serve as a valuable resource for researchers in SLA, psycholinguistics, linguistics, and language education.

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. .

Since the introduction of communicative language teaching, collaborative learning has played an important role in the second language (L2) classroom. Drawing from sociocultural theory, which states that human cognitive development is a socially situated activity mediated by language, studies in L2 pedagogy advocate the use of tasks that require learners to work together. Collaborative dialogue encourages language learning, and research shows that the solutions reached by students in this process are more often correct with a lasting influence on their language comprehension. This volume includes ten chapters that illustrate the benefits of collaborative dialogue in second foreign language classrooms. The volume considers key issues dealing with collaborative tasks and implications for language teaching.

How does classroom language learning take place? How does an understanding of second language acquisition contribute to language teaching? In answering these questions, Rod Ellis reviews a wide range of research on classroom learning, developing a theory of instructed second language acquisition which has significant implications for language teaching.

Evidence-Based Second Language Pedagogy is a cutting-edge collection of empirical research conducted by top scholars focusing on instructed second language acquisition (ISLA) and offering a direct contribution to second language pedagogy by closing the gap between research and practice. Building on the conceptual, state-of-the-art chapters in The Routledge Handbook of Instructed Second Language Acquisition (2017), studies in this volume are organized according to the key components of ISLA: types of instruction, learning processes, learning outcomes, and learner and teacher psychology. The volume responds to pedagogical needs in different L2 teaching and learning settings by including a variety of theoretical frameworks (sociological, psychological, sociocultural, and cognitive), methodologies (qualitative and quantitative), target languages (English, Spanish, and Mandarin), modes of instruction (face-to-face and computer-mediated), targets of instruction (speaking, writing, listening, motivation, and professional development), and instructional settings (second language, foreign language, and heritage language). A novel synthesis of research in the rapidly growing field of ISLA that also covers effective research-based teaching strategies, Evidence-Based Second Language Pedagogy is the ideal resource for researchers, practitioners, and graduate students in SLA, applied linguistics, and TESOL.

One of the key issues in second language learning and teaching concerns the role and practice of grammar instruction. Does it make a difference? How do we teach grammar in the language classroom? Is there an effective technique to teach grammar that is better than others? While some linguists address these questions to develop a better understanding of how people acquire a grammar, language acquisition scholars are in search of the most effective way to approach the teaching of grammar in the language classroom. The individual chapters in this volume will explore a variety of approaches to grammar teaching and offer a list of principles and guidelines that those involved in language acquisition should consider to design and implement effective grammar tasks during their teaching. It proposes that the key issue is not whether or not we should teach grammar but how we incorporate a teaching grammar component in our communicative language teaching practices.
