The book contains a selection of papers reflecting cutting-edge developments in the field of learning and teaching second and foreign languages. The contributions are devoted to such issues as classroom-oriented research, sociocultural aspects of language acquisition, individual differences in language learning, teacher development, new strands in second language acquisition research as well as methodological considerations. Because of its scope, the diversity of topics covered and the adoption of various theoretical perspectives, the volume is of interest not only to theorists and researchers but also to methodologists and practitioners, and can be used in courses for graduate students.
