The Computers in Bilingual Education (CIBE) program at South Bronx High School offered computer-assisted instruction in English as a second language (ESL), native language arts, social studies, mathematics, and science to limited-English-speaking students and provided instruction in computer literacy. It served 340 low-income ninth-, tenth-, and eleventh-grade Spanish-speaking students, mostly recent Puerto Rican immigrants. Classroom instruction was funded by several sources, and due to lack of experienced staff, some teachers taught outside their licensing areas. Program students made up over one-half of the school's graduating class. Since the program was strongly supported by the administration, its curriculum closely paralleled that of the mainstream. Analysis of student achievement data indicates: (1) English language development met or approached the objective in both semesters; (2) English, English reading, and native language course completion objectives were met; (3) content-area course passing objectives were met; (4) students achieved high passing rates in computer literacy; and (5) the attendance rate was significantly higher than that of mainstream students. Recommendations for improvement are given. (MSE)
