Input, Interaction, and the Second Language Learner by Susan M. Gass is a classic text in second language acquisition (SLA) that has been reissued in the Routledge Linguistics Classics series. Published in 1997, the book has been widely recognized for its contributions to the understanding of input, interaction, and SLA. The book provides an important perspective on the relationship between input, interaction, and SLA, and is useful for those interested in the acquisition of a second or foreign language, as well as those interested in pedagogical issues. The book does not advocate a particular teaching methodology, but rather attempts to explain the underlying processes of interaction and its role in language learning. The book is divided into seven chapters, each exploring different aspects of SLA, including the nature and function of output, the role of interaction, and the creation of learner systems. The book also includes a preface that discusses the development of the interaction approach in SLA over the past two decades. The preface includes a conversation between the author and three scholars, Alison Mackey, Rod Ellis, and Mike Long, who each contributed to the development of the interaction approach in SLA. The book has been widely cited and is considered an essential reference for scholars and students in the field of SLA. It has been reprinted in the Routledge Linguistics Classics series, which includes other important works in the field of linguistics. The book is a key text for all SLA scholars and an essential supplementary volume for students in SLA courses.Input, Interaction, and the Second Language Learner by Susan M.
