Dispelling the many myths about dual language development, the expert authors arm future professionals with the information they need to support young bilingual children and their families, all while meeting Head Start's guidelines on cultural and linguistic responsiveness. Preservice professionals will get a solid foundation of knowledge to help them

• address reading impairments in dual language learners (NEW CHAPTER!)
• minimize barriers to language development in internationally adopted children (NEW CHAPTER!)
• give children continuous, consistent, and rich exposure to both languages
• recognize the typical stages of second-language learning
• determine when a language delay is the result of an actual disorder
• prevent attrition of the child's first language
• make appropriate decisions about the schooling of dual language learners
• understand code mixing and successfully factor it into language assessments
• apply effective assessment strategies to accurately diagnose language impairments
• plan interventions that are culturally appropriate and respect the child's identity
• address parents' concerns and help them support their child's development in both languages

Undergraduate and graduate students will also benefit from detailed profiles of dual language learners, definitions of key terms, and summary sections that juxtapose key points with their implications for effective practice.

With the clear information in this state-of-the-art textbook—also a valuable resource for in-practice SLPs and educators—professionals will be ready to make informed decisions that help young dual language learners thrive, both at home and in the classroom.Dual Language Development & Disorders is a part of the Communication and Language Intervention Series

Martha B. Crago, Ph.D., has bachelor of arts, master's of science, and doctoral degrees from McGill Univerisity. Prior to becoming a professor in communication sciences and disorders at McGill, she worked as a speech-language pathologist. At present, Dr. Crago is McGill's Dean of Graduate and Postdoctoral Studies and Associate Provost (Academic Programs). Her research has focused on cross-linguistic and cross-cultural studies of Inuktitut, French, English, and Arabic across a variety of learners, including bilingual children as well as children with language impairments. Her research has been published in numerous articles, books, and book chapters. Dr. Crago has been the President of the Association des Doyen(nes) des Etudes Superieures du Quebec and President of the Canadian Association of Graduate Studies (CAGS) and a member of the Executive Board of the Council of Graduate Studies (USA). She also serves on a number of Canadian national committees and review boards, including the Standing Committee on Fellowships and Career Development of the Social Sciences and Humanities Research Council of Canada, Le Chantier du Releve des Fonds Quebecois de Recherche en Nature et Technologie, and the Steering Committee for the Evaluation of the Strategic Training Initiative in Health Research of the Canadian Institutes for Health Research.

Dr. Genesee is the author of nine books and numerous articles in scientific, professional, and popular journals and publications. He has carried out extensive research on alternative approaches to bilingual education, including second/foreign language immersion programs for language majority students and alternative forms of bilingual education for language minority students. This work has systematically documented the longitudinal language development (oral and written) and academic achievement of students educated through the media of two languages — their home language and another language. Along with Donna Christian and Liz Howard, Dr. Genesee is currently involved in a longitudinal study of a number of two-way immersion programs in the United States of America. He has consulted with poicy groups in Canada, Estonia, Germany, Hong Kong, Italy, Japan, Latvia, Russia, Spain, and the United States on issues related to second language teaching and learning in school-age learners. Dr. Genesee is also interested in basic issues related to language learning, representation, and use in bilingual children. His work in this domain focuses on simultaneous acquisition of two languages during early infancy and childhood; his specific interests include language representation (lexical and syntactic) in early stages of bilingual acquisition, transfer in bilingual development, structural and functional characteristics of child bilingual code-mixing, and communication skills in young bilingual children. A new line of research will examine the language/speech processing skills of preverbal bilingual and second language infants. Collectively, this work seeks to extend understanding of the limits of the human faculty for language acquisition, which, to date, has been based primarily on studies of monolingual acquisition.

Dr. Paradis completed her doctorate in psychology and pursued postdoctoral studies in communication disorders, both at McGill University. She has published numerous articles in scientific journals on bilingual and second language children, both typically developing and with specific language impairment (SLI). Before completing her doctorate, she taught English as a Second Language to adults and children for 10 years. Dr. Paradis is currently pursuing two lines of research. One line is concerned with bilingual children with SLI (e.g., Do bilingual children with SLI exhibit difficulties equally in both their languages? Do bilingual children with SLI exhibit more severe difficulties than monlingual children with SLI?). Her second line of research consists of comp
