The last few decades have seen extensive research focusing of the relative effectiveness of different instructional options that can be employed in teaching grammar structures (e.g., deduction and induction, different types of corrective feedback, input-based vs. output-based practice). However, the contribution of such pedagogical intervention and the resulting knowledge of target language grammar are mediated by a number of factors related to a specific context, the properties of the features being taught and, most importantly, individual learner profiles. Nonetheless, research into the moderating role of individual difference variables has been scant, limited to only several factors, and seldom taking into account complex interactions between variables. The book seeks to fill this evident gap by investigating the mediating effect of selected cognitive and affective factors on explicit and implicit (or highly automatized) knowledge of the English passive voice. In doing so, the study sheds the so-much-needed light on the predictors of second language grammar knowledge but also, to some extent, on the usefulness of instructional techniques used to develop it.

This book syntheses cutting-edge research on the role of individual differences (IDs) in the field of SLA and in computer assisted language learning. It also outlines the theoretical and methodological issues at the heart of this research, presents empirical findings and charts future directions of this research. Pawlak and Kruk provide an overview of the latest theoretical developments in research on IDs in SLA as well as methodological considerations that are crucial when researching individual variation, with special emphasis on data-collection procedures that are most prominent in CALL. The book goes on to summarize and explore a body of empirical evidence concerning the role of individual difference factors in CALL, singling out existing gaps, methodological problems, and areas in need of further investigation. Finally, the authors provide a guide on how empirical investigations of individual difference factors in CALL can be improved by incorporating latest developments from the broader field of SLA. This book will be of great interest to postgraduates and scholars in the domain of applied linguistics and second language education who are interested in CALL, as well as those studying and undertaking research in second language learning and teaching.

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 edited book brings together ten empirical papers reporting original studies investigating different facets of individual variation second language learning and teaching. The individual difference factors covered include, among others, motivation, self, anxiety, emotions, willingness to communicate, beliefs, age, and language learning strategies. What is especially important, some of the contributions to the volume offer insights into intricate interplays of these factors while others attempt to relate them to learning specific target language subsystems or concrete instructional options. All the chapters also include tangible implications for language pedagogy. The book is of interest to both researchers examining the role of individual variation in second language learning and teaching, teacher trainers, graduate and doctoral students in foreign languages departments, as well as practitioners wishing to enhance the effectiveness of second language instruction in their classrooms.

The scope of individual learner differences is broad, yet there is no current, comprehensive, and unified volume that provides an overview of the considerable amount of research conducted on various language learner differences, until now.

Expanding Individual Difference Research in the Interaction Approach: Investigating learners, instructors, and other interlocutors demonstrates why investigating the individual differences of all interlocutors with whom learners interact – including peer and heritage learners, instructors, researchers, and native speakers – is critical to understanding how second and foreign languages are taught and learned. Through state-of-the-art syntheses detailing what is known about learners and instructors, and novel empirical studies highlighting new avenues of inquiry, the volume articulates the most pressing needs for individual difference research. The book concludes with a scoping review, which reveals the many interlocutors still yet to be empirically considered and outlines next steps for this research. Uniquely combining linguistic theory, research synthesis, and empirical study, this book encourages students and established scholars alike to expand their conceptualization of individual differences. By demonstrating the importance of considering the individual differences of all interlocutors, the studies are also highly relevant to those teaching second and foreign languages in diverse contexts.

Beginning from the conflict between individual learner differences and the institutionalized, often inflexible character of formal language instruction, Individual Learner Differences in SLA addresses the fact that despite this apparent conflict, ultimate success in learning a language is widespread. Starting with theoretically-based chapters, the book follows the thread of learner differences through sections devoted to learner autonomy; differentiated application of learning strategies; diagnostic studies of experienced learners’ management of the learning process; and reports on phonological attainment and development of language skills. Rather than providing an overview of all individual variables, the book reveals how some of them shape and affect the processes of language acquisition and use in particular settings.
