This book addresses fundamental questions regarding the relationships between successful language learning and strategy use and development according to learner, situational or target variables. It considers strategy effectiveness from an individual point of view and discusses pedagogical issues, especially relating to teacher perceptions and training, classroom and learner factors, methodology and content. The book begins by discussing underlying theoretical issues and then presents evidence from empirical studies; in addition to presenting a quantitative view, the book also takes a qualitative look at strategy use by individuals. Rather than focusing on strategies divorced from the 'real world' of the classroom, this book explores the issues from the teaching/learning point of view.
