After a solid review of the fields of bilingual education, English as a second language (ESL), world/foreign language education, and language policy and planning, Freeman offers an ethnographic account of bilingualism and education in the Puerto Rican community in Philadelphia. This account shows how individual teachers and teams of educators have organized tbeir policies, programs and practices to promote bilingualism through schooling on the local school and school district levels. The book concludes by outlining how educators working in other contexts can develop language policies, programs, and practices that address the needs of the students and communities they serve.
