Special attention to the implications of world health problems and the effectiveness of international understanding and cooperation in alleviating harmful health conditions is given in this prototype curriculum for grades 10-12. The importance of student participation and ultimate involvement and commitment to world health problems is reflected. Specific curriculum content studies: (1) international cooperation, (2) health personnel throughout the world, (3) the World Health Organization, (4) world health problems (environmental health, global diseases and control, world nutrition, health research), and (5) implications of global health (cultural influences, population concerns, health education, space medicine). Appended material includes bibliographies of multimedia resources for teachers and students. This publication is one in a series of health curriculum materials devoted to environmental and community health (Strand IV). Four other strands deal with physical and mental health, sociological health problems, and education for survival. The format consists of four columns intended to provide teachers with (1) a basic content outline, (2) major understandings and fundamental concepts, (3) teaching aids and learning activities, and (4) information about resource materials, sources, and personnel. Because of the comprehensive nature of the total curriculum, teachers are advised to become familiar with all strands presently in print. Related documents in Strand IV are ED 037 738-9, ED 049 477-8, and SE 016 280-6. (BL)
