This report summarizes the activities of the California Mathematics Project established in 1983 using survey data, classroom observations, and interviews. The central goal of this program was to provide leadership in improving the quality of mathematics instruction throughout the state of California. Information was collected for use in planning re-training programs for secondary mathematics teachers. The survey results indicate that a proportion of teachers are new-to-mathematics instruction, teach mathematics on a part-time basis, and have transferred to their current position from non-mathematics departments within the same district. Problems with problem solving, the lack of computer integration, responses to student needs, modeling, student motivation, socio-economic level, teaching schedules, class size, teaching style, and job satisfaction are identified from class observations and interviews. Recommendations are included. (KR)
