As a Senior Research Associate with WestEd's Center for Child & Family Studies (CCFS), Ann-Marie Wiese focuses on issues related to the education of young dual language learners. Her work has contributed to state policy, discussions at the national level, and the professional development of practitioners.

Wiese has contributed to the development of preschool foundations in English language development and an accompanying curriculum framework for the California Department of Education, Child Development Division (CDE/CDD). As part of the CCFS English Learning for Preschoolers Project, Wiese helped lead a pilot series of trainings that reached more than 2,000 preschool educators throughout California. The purpose of these trainings was to disseminate the resource guide, Preschool English Learners: Principles and Practices to Promote Language, Literacy, and Learning, and the bilingual (English/Spanish) DVD, "A World Full of Language," which won a Telly Award for excellence in video production.

Most recently, Wiese serves as Project Director of the California’s Best Practices for Young Dual Language Learners Project, a collaboration with the CDE/CDD to provide guidelines for preschool programs that serve young dual language learners, in the form of both print resources and a video resource based on the most current research and evidence. Wiese also served as lead developer for WestEd's English Learners, Language, and Literacy in the Early Years (ELLLEY), a professional development effort for preschool practitioners who work with young bilingual children. Through a series of core seminars and on-site coaching, practitioners learn about best practices and theoretical foundations that foster the language and literacy development of young bilingual children. The project completed its fourth and final year in San Francisco, reaching numerous teachers through seminars and teachers through coaching. In addition, teachers in San Diego and Monterey counties have participated in the seminars.

Wiese previously worked for WestEd's Quality Teaching for English Learners project. Prior to joining WestEd, she was an Assistant Professor of Education at the University of California at Santa Cruz, where she taught courses on first and second language acquisition, teaching methods for English language development, and bilingual literacy development and instruction. She began her career as an early elementary Spanish-bilingual teacher.

Wiese has published articles in the International Journal of Bilingual Education and Bilingualism; Bilingual Research Journal; and the Handbook of Research on Literacy and Diversity. Most recently, she authored a chapter for the Handbook of Research on the Education of Young Children.

She regularly presents at national and local conferences such as the California Association for the Education of Young Children. She co-organized the California Association for Bilingual Education Institute, "Early Childhood Education for Bilingual Children in California: Drawing on National Research and Promising Practice" in 2008.

In 2007, she participated in a working group called by the National Task Force for Hispanics in Early Childhood Education. She also serves as an active member of the San Mateo County Child Care Partnership Council and the School Site Council for a local two-way immersion elementary school.

Wiese received a PhD in Education (language, literacy, and culture) from the University of California, Berkeley.
