This landmark volume offers a collection of conceptual papers and data-based research studies that investigate the dynamics of language learning motivation from a complex dynamic systems perspective. The chapters seek to answer the question of how we can understand motivation if we perceive it as a continuously changing and evolving entity rather than a fixed learner trait.

This volume - the second in this series concerned with motivation and foreign language learning - includes papers presented at a colloquium on second language motivation at the American Association for Applied Linguistics as well as a number of specially commissioned surveys.

Second/foreign language (L2) speech production is a complex process requiring individuals’ combined efforts to utilize various processing components such as conceptualiser, formulator, and articulator. Since the publication of Pim Levelt’s book Speaking – From Intention to Articulation in 1989, a considerable number of studies have examined L2 speech production in the field of neuroscience with a particular focus on the link between speech perception and speech production. Undeniably, a neurolinguistic examination of speech production can enrich our understanding of how human brains compute linguistic information at a cognitive level. However, it is insufficient by only focusing on the neurocognitive dimension of speech production, given that individuals’ speech production can be subject to various individual differences factors, either cognitively, affectively, or socio-culturally. It is, therefore, necessary to move beyond the neurocognitive understanding of speech production by taking every possible perspective into consideration. Individual difference, as an umbrella term, covers psychological traits, personal characteristics, cognitive and emotional components that distinguish learners from each other. Given that individual difference factors can reveal disparities in L2 learning and performance among learners, such factors have attracted researchers’ growing interest concerning their influences on L2 speech processing, their relationships with L2 speech performance, and their contributions to L2 speech development. Nevertheless, our understanding of L2 speech production is not only insufficient compared to other L2 skills such as writing and reading, but also limited to the neurocognitive account of L2 speech production. More research, therefore, is in urgent need to uncover the influence of various individual differences factors on L2 speech production from multidisciplinary perspectives.

This edited collection provides a state-of-the art overview of research on willingness to communicate (WTC) in a second and foreign language. In particular, it includes innovative studies seeking to demonstrate the ways in which WTC can be examined within the framework of complex dynamic systems, how the construct is related to self-assessment, reticence and extroversion, and what is signifies in the case of immigrants. Another group of papers is related to the role of technology in fostering WTC in different contexts. The volume also comprises papers that touch on methodological issues in the study of WTC such as experience case sampling, the network approach or the integration of the macro- and micro-perspective. The book will be of values to researchers interested in the study of WTC but will also provide inspiration for students, teachers and materials writers.

This book offers a comprehensive account of individual differences variables as well as contextual factors that impinge on second language learners’ willingness to communicate (WTC). Firstly, it adopts a macro-perspective on WTC, which entails an attempt to identify variables that are related to WTC, taking into account the specificity of the Polish higher education setting. Secondly, it embraces a micro-perspective on WTC, striving to pinpoint the individual and contextual influences on levels of WTC in the course of regularly-scheduled, naturally-occurring English classes, as well as to capture the dynamic nature of WTC during such classes. Together, these perspectives bring the reader closer to understanding the mechanisms underlying WTC in specific contexts, thereby providing a basis for recommendations for classroom practice that could translate into learners’ success. It will be of interest to second language acquisition researchers and students, as well as to methodologists and materials writers who can use the research findings to improve the practice of teaching and learning speaking in the language classroom.

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.

This book focuses on the dynamic relationships among individual difference (ID) variables (i.e., willingness to communicate, motivation, language anxiety and boredom) in learning English as a foreign language in the virtual world Second Life. The theoretical part provides an overview of selected issues related to the four ID factors in question (e.g., definitions, models, sources, types, empirical investigations). The empirical part reports the findings of a research project which aimed to examine the changing nature of WTC, motivation, boredom and language anxiety experienced by six English majors during their visits to the said virtual world, the main contributors to the changes in the levels of the constructs under investigation, as well as their relationships. The book closes with the discussion of directions for further research as well as pedagogical implications.

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.

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.
