This volume brings together a collection of chapters focused on the learning, testing, and researching of L2 vocabulary by leading international researchers including Paul Nation, Batia Laufer, Frank Boers, Elke Peters, Ana Pellicer-Sánchez, Anna Siyanova-Chanturia, and Stuart Webb. Questions that are examined include: Is it useful to read a book to learn vocabulary? Which types of input encountered outside of the classroom contribute most to vocabulary knowledge? What are the most useful words to learn to understand the academic spoken language in mathematics, biology, and engineering lectures? Does writing words contribute to vocabulary learning? What should a test measuring the skill of guessing from context consist of? Should loan words be included in vocabulary tests? How should we evaluate vocabulary learning that occurs through watching captioned video? How has eye-tracking been used in vocabulary research? Together, the chapters in this volume highlight innovation in vocabulary studies and many directions for researching, testing, and learning words.

Incidental language acquisition is the language that is learned informally, outside the constraints of the typical classroom, and vocabulary is one of the key elements in language learning and knowledge. This unique text is the first comprehensive overview and hands-on methodological guide for researching second language (L2) incidental vocabulary acquisition. Expert contributors from around the world synthesize the state of the art by defining key concepts and laying out the major theoretical perspectives, research methodologies, empirical findings, and pedagogical considerations involved in incidental L2 vocabulary learning research. By connecting research techniques to the theory that underpins them, detailing practical steps for designing and conducting rigorous new studies, and highlighting areas that deserve additional research attention, they further set the agenda for future work in this field and put readers in a strong position to understand and carry out this research independently. This book will be an invaluable resource to advanced students and researchers of second language acquisition, vocabulary studies, applied linguistics, education, and related areas.

This guide to vocabulary acquisition is essential reading for teachers of English as a second or foreign language. It presents the major ideas and principles that relate to the teaching and learning of vocabulary and evaluates a wide range of practical activities designed to help boost students’ vocabulary acquisition. Key questions which are answered include: • How many words should students learn at a time, and how often? • How much classroom time should be spent teaching vocabulary? • What is the best way to group vocabulary for learning? • Is it useful to provide students with the L1 translations of unknown words? • Why do some students make greater progress than others? stuart webb is Professor in Applied Linguistics at the University of Western Ontario, Canada. paul nation is Emeritus Professor in Applied Linguistics at Victoria University of Wellington, New Zealand. Teachers will find answers to many of their perennial questions about vocabulary learning—as well as some they had not yet thought to ask! There is research evidence to support established practices, but also new evidence that challenges old ideas. patsy lightbown (co-author of How Languages are Learned, with Nina Spada)

This research- and pedagogy-oriented book delves into the study and application of incidental vocabulary acquisition in English through captioned videos. This technology offers EFL students of different ages more opportunities for vocabulary learning compared to the traditional classroom. This book reviews the conceptual, methodological, theoretical, and practical issues associated with captioned videos and offers innovative ideas to help researchers, graduate students, and classroom practitioners enhance learners' vocabulary acquisition at all levels.

The eleven chapters of Vocabulary in a Second Language are written by the world's leading researchers in the field of vocabulary studies in second language acquisition. Each chapter presents experimental research leading to new conclusions about and insights into the selection, the learning and teaching, or the testing of vocabulary knowledge in foreign languages. This book is intended as an up-to-date overview of the important domain of the lexicon for researchers in the field of second language acquisition, teacher trainers and professional teachers of second or foreign languages.

This book provides pedagogical suggestions for both teachers and learners.
