Detailed descriptions about Project Physics are presented in this report covering the period from July 1, 1964 - August 15, 1970. The objectives of designing a humanistically-oriented course, attracting more senior-high students, and contributing to the advancement of knowledge of the factors influencing physics learning are discussed with a background of the project. Physicists, scientists, educators, historians of science, and school teachers and students were involved in the project in its trial period. Textbook units are analyzed by using flow charts of conceptual outlines. Also included are tests, reader articles, teacher resource books and briefing films, experimental equipment, film loops, sound films, transparencies, and programmed instruction materials. Evaluations were conducted to improve the course and obtain user information. Findings are analyzed on the subjects of methodology, teachers, students, and learning environments. Enrollments in Project Physics are estimated to increase from 20,000 in 1969-70 to 115,000 in 1971-72, and the total pattern of educational activities is influenced by the project. Original documents and lists of course materials are contained in the appendices, some of which are included in another volume (SE 015 501). A teacher-preparation plan is also provided. (CC)
