Whether we grow up with one, two, or several languages during our early years of life, many of us will learn a second, foreign, or heritage language in later years. The field of Second language acquisition (SLA, for short) investigates the human capacity to learn additional languages in late childhood, adolescence, or adulthood, after the first language --in the case of monolinguals-- or languages --in the case of bilinguals-- have already been acquired. Understanding Second Language Acquisition offers a wide-encompassing survey of this burgeoning field, its accumulated findings and proposed theories, its developed research paradigms, and its pending questions for the future. The book zooms in and out of universal, individual, and social forces, in each case evaluating the research findings that have been generated across diverse naturalistic and formal contexts for second language acquisition. It assumes no background in SLA and provides helpful chapter-by-chapter summaries and suggestions for further reading. Ideal as a textbook for students of applied linguistics, foreign language education, TESOL, and education, it is also recommended for students of linguistics, developmental psycholinguistics, psychology, and cognitive science.

Second Language Learning and Language Teaching provides an introduction to the application of second language acquisition research to language teaching. Assuming no previous background in second language acquisition or language teaching methods, this text starts by introducing readers to the basic issues of second language acquisition research. It then examines how people learn particular aspects of the second language, such as grammar, vocabulary, pronunciation and the writing system, and at the strategies they adopt in their learning and the differences between individuals. Final chapters look at second language learning in a broader context – the goals of language teaching and how teaching methods relate to SLA research. This newly updated fifth edition builds on the comprehensive scope of earlier editions while also addressing more recent developments in the field, particularly multilingual approaches to language teaching.

- How do I plan a lesson? - How will I know if my students are learning? - How do I teach language while also teaching content material? - How do I effectively use technology in language teaching? - How can I ensure the academic success of my students? - How can I help my students have more contact with the new language? These are the practical questions language and mainstream teachers struggle with as they enter today’s diverse classrooms in an era when they must focus not only on their everyday teaching, but also on students’ second language development. The answers to these questions and more are here, in this much-needed, comprehensive, practical guide to language teaching in second foreign, and content-based settings. In a warm, supportive tone, respected author and experienced language teacher Elaine K. Horwitz clearly explains the fundamental concepts of second language acquisition and language teaching, using actual classroom situations that help students learn to make instructional decisions in their own future teaching settings. Unique among other methods texts that emphasize language for communication purposes only, Becoming a Language Teacher also focuses on language for academic needs, while addressing the latest trends in language teaching as well as effective approaches for teaching language in content classes. The perfect choice for ESL and Foreign Language methods courses, this guide helps teachers develop a personal approach to language teaching, suited to their own unique teaching situations. Major additions to the text are related to socio-cultural approaches to second language acquisition and teaching. The Second Edition also includes: - Expanded coverage of language development and content teaching - Coverage of The Output Hypothesis, Sociocultural Theories of SLA, the SIOP Method and the CALLA Approach - Publication of the long-awaited revision of the Beliefs about Language Learning Inventory, BALLI - An Assessment for Learning approach to student testing added to Chapter 8 - Suggestions for using new technologies and digital media incorporated throughout - Added explanations of Emergent Bilingual, Heritage Learners, Dual Language programs, World Languages, Sheltered English, Newcomer Centers, Self-Access Language Learning Centers, Willingness to Communicate, and Language Learner Autonomy

In the 30 years since Rod Ellis first published the award-winning Understanding Second Language Acquisition, it has become a classic text. This new, fully updated edition continues to provide an authoritative and highly readable introduction to key areas of theory and research in second language acquisition. Ellis presents a comprehensive overview of the different theories in this field and examines critical reactions to them. The book reflects recent trends in looking at cognitive and social aspects of second language acquisition, as well as examining the roles played by implicit and explicit instruction in language learning. “An excellent and much-needed, in-depth review of the research on how children and literate adults learn a second language. Ellis provides a sound knowledge base for language teachers and beginning graduate students in applied linguistics, focusing on relevant findings of research on second-language learning by children and literate adults in both naturalistic and instructed contexts.” Elaine Tarone, Director of the Center for Advanced Research on Language Acquisition, University of Minnesota Additional online resources are available at www.oup.com/elt/teacher/understandingsla Rod Ellis is the Distinguished Professor of Applied Language Studies in the School of Cultures, Languages and Linguistics in the University of Auckland.

The defacto standard - a must-have for all LISP programmers. In this greatly expanded edition of the defacto standard, you'll learn about the nearly 200 changes already made since original publication - and find out about gray areas likely to be revised later. Written by the Vice- Chairman of X3J13 (the ANSI committee responsible for the standardization of Common Lisp) and co-developer of the language itself, the new edition contains the entire text of the first edition plus six completely new chapters. They cover: - CLOS, the Common Lisp Object System, with new features to support function overloading and object-oriented programming, plus complete technical specifications * Loops, a powerful control structure for multiple variables * Conditions, a generalization of the error signaling mechanism * Series and generators * Plus other subjects not part of the ANSI standards but of interest to professional programmers. Throughout, you'll find fresh examples, additional clarifications, warnings, and tips - all presented with the author's customary vigor and wit.
