A summary report is presented of the evaluation of the Core French Review conducted in North York schools in Ontario (Canada) during the 1987-88 academic year. A Core French program is one in which French as a second language is taught as a regular subject to students in an English-language school. Since September 1984, students have started Core French in grade 3 and accumulated 600 hours of French instruction by the end of grade 8. Students in grades 3 and 4 receive 20 minutes of daily instruction, and students in grades 5 through 8 receive 40 minutes of daily instruction. The review design covered curriculum documents and student learning materials, program implementation practices, staffing, parental perceptions, program outcomes, and professional development needs. Data collection involved group interviews with 13 Core French teachers and 4 principals, achievement testing of 808 eighth graders in the area of French listening, surveys of and interviews with members of 4 Boards of Education, observation of 72 fifth- and eighth-grade classrooms, individual interviews with 24 teachers, group interviews with 6 parents, and questionnaires administered to 149 teachers and 89 principals. Results and recommendations are provided in each area covered, and are organized into strong points and points needing attention. Thirteen graphs are included. (TJH)
