Muriel Saville-Troike is Professor Emerita of the University of Arizona, and was named Regents' Professor of English before her retirement. She has made significant contributions to the fields of sociolinguistics and applied linguistics, and has previously held posts at Texas A&M University, the University of Texas, Georgetown University, and the University of Illinois. Saville-Troike is a past President of TESOL, and was made a Distinguished Scholar by the American Educational Research Association Standing Committee on the Role and Status of Minorities in Educational Research. Karen Barto holds an interdisciplinary PhD in Second Language Acquisition and Teaching from the University of Arizona, and is a Content Developer and Lecturer at the university's Center for English as a Second Language. She has taught French, English applied linguistics and English as a second language in several contexts. She has designed, developed and taught teacher training classes and programs, as well as conducting linguistic and psycholinguistic research. Also an avid student of foreign language herself, she has studied French, German, Italian, Spanish, Lao and Latin.

'… combines great clarity of exposition, a focus on the linguistics of second language acquisition, and an effort to integrate diverse theoretical perspectives into a complex understanding of second language acquisition as a whole - all in less than 300 pages. While billed as a textbook for undergraduates, this text could easily be used in graduate-level introductory courses in second language acquisition. The chapter-ending discussion questions and activities, as well as a handy glossary of terms, make this more than just a textbook, however: it provides many of the materials needed to design an introductory course in the subject.' Dwight Atkinson, University of Arizona
