The ecological perspective on language and language education has in recent years become a major focus of interest in the fields of second language teaching and learning, and linguistics and education in general. This is the first book-length attempt to provide a comprehensive overview of an ecology of language learning, including both theoretical discussions on language, semiotics, emergence, and self, and the practical consequences of an ecological view for classroom work. This book is of interest to all language educators, second and foreign language teachers and researchers, and other education professionals.
