Offers an invaluable overview of what is known from empirical research about listening, reading, speaking, writing, vocabulary, and grammar strategies. Proposes a clear and focused research agenda for the next decades. Research into language learner strategies has the fundamental goal of improving the teaching and learning of second languages. This book explores the notion that the reason some learners of second languages excel and others struggle lies in what the learners themselves do-the strategies they bring to language learning and to language use.
