Presented in this report are a program description and the results of evaluation of the Basic Bilingual Program implemented at John Bowne High School in New York City during 1980-81. The program provided instruction in English as a Second Language, instruction in Spanish language skills, and bilingual instruction to high school students of limited English proficiency. The report describes the project context and student characteristics, and discusses the program philosophy, organizational structure, student placement, instructional program, funding and personnel, staff development, curriculum development, supportive services, and parent/community involvement. Patterns of student attendance, student behavior, plans for further education, and participation in extracurricular activities are examined as indicators of students' attitudes toward the program. Results of evaluation of student achievement in English, Spanish, mathematics, social studies, science, and business education are provided. Evaluation suggests that the program was generally effective, and the report identifies factors responsible for program success. Recommendations to ensure program continuity after the termination of Title VII funding are presented. (MJL)
