Dual language learners are the fastest-growing segment of the U.S. student population, and the majority speak Spanish as a first language. This graduate-level textbook-now in its third edition-gives future speech-language pathologists the comprehensive knowledge they need to work effectively with Spanish-English bilingual children and support their language development.
