Based on a state-of-the-art review of prior research in all related domains, this book makes precise predictions about the expected effects of specific type and token frequency distributions in input floods, and tests these in the second language classroom context.

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.

The volume contains a collection of studies on how the analysis of corpus and psycholinguistic data reveal how linguistic knowledge is affected by the frequency of linguistic elements/stimuli. The studies explore a wide range of phenomena , from phonological reduction processes and palatalization to morphological productivity, diachronic change, adjective preposition constructions, auxiliary omission, and multi-word units. The languages studied are Spanish and artificial languages, Russian, Dutch, and English. The sister volume focuses on language representation.

Frequency has been identified as one of the most influential factors in language processing, and plays a major role in usage-based models of language learning and language change. The research presented in this volume challenges established models of linguistic representation. Instead of learning and processing language compositionally, larger units and co-occurence relations are at work. The main point taken by the authors is that by studying the effect of distributional patterns and changes in such patterns we can establish a unified framework that explains the dynamics of language systems with a limited set of processing factors.

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.

This book is a systematic attempt to address the issue of fossilization in relation to a fundamental question in second language acquisition research, which is: why are learners, adults in particular, unable to develop the level of competence they have aspired to in spite of continuous and sustained exposure to the target language, adequate motivation to learn, and sufficient opportunity to practice?

This book presents a set of compelling essays collectively making a persuasive case for why a usage-based perspective on language is fast becoming a leading theoretical framework for investigating second language (L2) learning and the foundation for effective, innovative, engaging pedagogy. Drawing on 20 years of research in psychology, psycholinguistics, cognitive science, and linguistic theory, including discourse analytic approaches, the combined contributions paint a picture of theoretically-informed L2 pedagogy which emphasizes all facets of language as meaningful, embodied, and socially situated. The introduction and conclusion offer an outline of five foundational tenets essential to a usage-inspired pedagogy and a heuristic for developing usage-inspired L2 research and pedagogy. Each essay provides a unique vantage on usage-inspired L2 instruction and a demonstration of the efficacy of usage-based pedagogy. This volume will be invaluable for SLA researchers, graduate students, and classroom teachers interested in exploring usage-inspired L2 pedagogy.

Instructed Second Language Acquisition of Arabic examines the acquisition of agreement asymmetries in the grammatical system of Arabic as a second/foreign language through the lens of instructed second language acquisition. The book explores how to improve the processes of L2 learning of Arabic using evidence-based classroom research. Before it does this, it characterizes the variable challenges that English L2 learners of Arabic face when they acquire four structural cases in Arabic grammar that entail agreement asymmetries. Using the pretest–posttest design, it examines the effects of four classroom interventions using quantitative and qualitative measures. In these interventions, form-based and meaning-based measures were used to reveal to what degree learners have developed explicit and implicit knowledge of these aspects of asymmetry. In the concluding chapter, the book provides focused and specific implications based on the results of the four studies. It provides theoretical implications that enrich the discussions of instructed second language Acquisition in Arabic and other languages more broadly. It also provides implications for teachers, curriculum designers, and textbook writers of Arabic. This book will be informative for Arabic applied linguists, researchers of Arabic SLA, Arabic instructors (at the K–12 and the college level), and Arabic program directors and coordinators. The book will also appeal to all SLA and ISLA researchers.

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. .
