What makes good language learners tick? What do they do that poor learners don't do? Could we help the poor learner by teaching them some of the good learners' tricks? The nature of second language learning is extremely complex and a great deal of research is needed to improve our understanding of it. In spite of much theorizing, very little has been done to study its processes directly and empirically. This study constitutes a beginning. It sets out to discover the strategies of good language learners. The book will be useful not only to researchers, but also to teachers and to those who make language teaching policy.
