Reading ability and vocabulary knowledge are two of the most important components of performance in a second language, especially in academic settings. Each depend on the other, as vocabulary knowledge is the single most important factor in reading comprehension, while reading is the single most important means by which intermediate and advanced learners acquire new words. This symbiotic relationship is the subject of this volume. The authors argue that building vocabulary through reading is a fruitful but complex activity that needs better understanding and more careful guidance. This book is unique in its emphases on original research. Eight of the 14 chapters are empirical studies published for the first time, including classroom-based case studies, experimental research, and think-aloud protocol analysis. In every chapter, consideration is given to the pedagogical implications and possible applications of the research findings. Lengthy editorial comments at the end of each chapter reinforce this practical concern.
