This guide is intended as a reference for both parents and teachers concerning the design and objectives of two-way bilingual language immersion programs in elementary schools, including procedures and considerations in the creation of a new program. The first section looks at the role of language immersion as a form of enrichment education, and outlines different immersion program models. The second section examines attitudes toward language, language education, and bilingualism and the importance of community readiness in developing an immersion program. Section three addresses the planning and organization of a two-way immersion program, focusing on such issues as community demographics and the involvement of local school authorities. Parental involvement in the program is discussed in the fourth section. The challenges specific to the first 6 weeks of the program, the function of an immersion parent advisory committee, and issues in home-school cooperation are addressed in this section. In the final section, selected successful two-way immersion programs are profiled and a more extensive case study of one Arlington (Virginia) program is presented. Contains 20 references. (MSE)
