Students from Lafayette High School and Pershing Intermediate School in Brooklyn, New York who were of Spanish and Cantonese linguistic backgrounds (and who scored at or below the 40th percentile on the Language Assessment Battery) received intensive instruction in English-as-a-Second-Language (ESL) and native language arts (NLA) in Spanish or Cantonese. Although only 73 students were enrolled in the project, data is provided for a greater number of students. Instruction in math, social studies, science, and computer science was provided in Spanish or Cantonese. Teachers, students, and consultants designed, assembled, and tested a series of science modules; curriculum and staff development components focused on improving the hands-on, process, and concept-based scientific experiences. The project met its objectives for Chinese NLA, content area subjects, the career education objective for the organization of a career conference and advisement, attendance rates, dropout prevention, and parental involvement. The project did not meet its objectives for ESL, staff awareness of pupil needs and problems, and staff development. Data collection and analysis methods and instructional materials are appended. (JP)
