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 book defines engagement for the field of language learning and contextualizes it within existing work on the psychology of language learning and teaching. Chapters address broad substantive questions concerned with what engagement is or looks like, and how it can be theorized for the language classroom; methodological questions related to the design, measurement and analysis of engagement in language classrooms and beyond; as well as applied issues examining its antecedents, factors inhibiting and enhancing it, and conditions fostering the re-engagement of language learners who have become disengaged. Through a mix of conceptual and empirical chapters, the book explores similarities and differences between motivation and engagement and addresses questions of whether, how and why learners actually do exert effort, allocate attention, participate and become involved in tangible language learning and use. It will serve as an authoritative benchmark for future theoretical and empirical research into engagement within the classroom and beyond, and will be of interest to anyone wishing to understand the unique insights and contributions the topic of engagement can make to language learning and teaching.

This book provides practical guidance on research methods and designs that can be applied to Complex Dynamic Systems Theory (CDST) research. It discusses the contribution of CDST to the field of applied linguistics, examines what this perspective entails for research and introduces practical methods and templates, both qualitative and quantitative, for how applied linguistics researchers can design and conduct research using the CDST framework. Introduced in the book are methods ranging from those in widespread use in social complexity, to more familiar methods in use throughout applied linguistics. All are inherently suited to studying both dynamic change in context and interconnectedness. This accessible introduction to CDST research will equip readers with the knowledge to ensure compatibility between empirical research designs and the theoretical tenets of complexity. It will be of value to researchers working in the areas of applied linguistics, language pedagogy and educational linguistics and to scholars and professionals with an interest in second/foreign language acquisition and complexity theory.
