This is the final report of the High School Geography Project (HSGP), born of a joint committee of the National Council of Geographic Education and the Association of American Geographers, 1959-1961. Chapter one presents an interim, rather than final, assessment of the project as it stood in the summer of 1970, at its completion. Chapter two discusses the principle materials of the project, its objectives, teaching strategies, and content. Chapter three is a personal account of decisions and actions from 1964-1969, having a basic impact on the evolution of the final product. Chapter four examines the role of evaluation in the development of HSGP materials. Chapter five describes the preparation and dissemination of teacher education materials. The social history of the project is set forth in chapter six. The body of the report concludes in chapter seven with a look ahead toward further, recommended action. The appendices include a list of project participants, a project chronology, a list of project publications, an inventory of project materials, all the overview charts for the project units, a bibliography on the project itself, and a summary of financial support and expenditures.
