This practical guide includes information from a 3-year study that set out to describe the range of practices in content-English-as-a-Second-Language (content-ESL) programs in the United States. The guide is based on the field reports of 20 school site visits; offers guidance for starting, implementing, and sustaining a content-ESL program; and includes actual program projects and examples. The overall study assessed effective content-ESL programs across the United States, from pre-kindergarten through grade 12. The purpose of the study was to develop a descriptive analysis of the nature and scope of these programs and the relationship between program policies and practices and background notions of content-language integration. Suggestions and resources are provided in this volume for educators interested in finding out more about content-ESL programs in other schools, and a postscript relates the findings of the report to the Goals 2000 Educate America Act. Appendixes include the 20 field reports, tests, surveys, and actual program materials from content-ESL programs across the United States. Contains three pages of references and numerous tables.) (NAV)
