This book presents the latest research on the role of strategy use and development in second and foreign language teaching and learning. It comprises a wide selection of studies which cover topics such as strategic training of young EFL learners, promoting critical thinking through video gaming, language learning strategies for languages other than English, and the contribution of language learning strategies to the development of the four language learning skills. It will equip scholars and practitioners with the knowledge to help them better appreciate how language learning strategies contribute to and are linked with language learning processes. The contributing authors share research from their various contexts, which range from primary to tertiary education, and discuss the need for fine-tuned strategy categorization, conscious self-regulation and proposed strategy instruction.
