"This is an interdisciplinary book that...effectively illustrates the impact of the sociocultural perspective proposed by Vygotsky by describing its applicability to the language learning process of a wide range of groups...The major contribution of this book is...the demonstration of the versatility and generalizability of the Vygotskian theory. The maxim that there is nothing better than a good theory is clearly proven in this book." Chieh Li and Ena Vasquez Nuttall, Contemporary Psychology
