Second Language Acquisition: An Introductory Course Third Edition Susan M. Gass, Larry Selinker The much anticipated revision of this bestselling textbook offers a comprehensive, state-of-the-art overview of the SLA. The accessible format is designed for use in introductory second language acquisition course taken by undergraduate and graduate students studying second language acquisition or applied linguistics in a variety of departments. Changes in the textbook reflect changes in the field: the field of SLA is now even more interdisciplinary than it was at the time of the previous edition. Continuing the previous editions' successful tradition of a clearly written and illustrated presentation, an emphasis on empirical findings, and the up-to-date research, the Third Edition offers a new chapter on "SLA and Related Disciplines" discussing multilingualism; new sections about the relationship between L1 and L2 acquisition, language transfer, sociocultural theory, working memory, among other changes. The authors believe strongly that the follow-up activities and Points for Discussion (many of which are new to this edition) are as important as the descriptive summaries of SLA issues. The structured data problems allow students to gain hands-on experience with what language learners do and do not produce. The goal of the text is to encourage a new generation of second language researchers and educators. Susan M. Gass is University Distinguished Professor in the Department of Linguistics and Germanic, Slavic, Asian and African Languages at Michigan State University. Larry Selinker is one of the original contributors to the research field of Second Language Acquisition. Currently, he is Visiting Professor at New York University.
