Reported is a project designed to develop and implement a secondary school physics program that allowed for student variation in individual learning style, mathematical aptitude and topical interests. Initiated in 1967, this four-year individualized, modular program is divided into four major phases: (1) introductory and instruments, (2) mechanics, thermodynamics, fluids, (3) wave motion, electromagnetism, electronics, and (4) modern physics. Each phase is subdivided into topics, which are highly structured in the beginning but yield gradually into independent study units. This report describes the project objectives, the Physics Center where the program was conducted, the methods used, the evaluation procedures, and the outcomes of the program. There is a comparison with the traditional approach. A number of specific recommendations concerning the program was made. The appendices identify the basic phases, the levels in each phase, and the topics in phase I. (LC)
