This book is an introduction to Vygotsky and his theories of language and second language acquisition. Employing a dual framework of metatheory and metaphor, the author focuses on Vygotsky's cultural-historical perspective (contrasted with the sociocultural heritage more prevalent in the West) and its emphasis on history as change and thought as related to action. Included also is a comparison of Vygotskyan and Chomskyan theories of language and grammar.
