"Second Language Learning Theories is an introduction to the field of second language learning for students without a substantial background in linguistics. Drawing on the expertise of both a specialist in the teaching of second languages and a linguist specialising in second language acquisition, this textbook provides an up-to-date introductory survey of the most active and significant perspectives on the subject." In this new edition, the authors have revised and updated the text throughout to reflect the substantial developments that have taken place in the field in recent years. New studies have been incorporated as examples, and theoretical advances are presented and explained. The evaluation sections in each chapter have been expanded and generally the book is rebalanced in favour of newer material.
