This health curriculum guide, intended for use with grades seven through nine, places considerable emphasis on the understanding that current knowledge of disease prevention has an impact on the incidence of prevalence of communicable diseases. The contents of the guide are presented in outline form and cover historical development of man's knowledge of disease, ecological relationships, communicable disease, resurgence of venereal disease, and degenerative disease. For each content area and its sub-divisions fundamental concepts and understandings, teaching aids, and learning activities are suggested. The guide also supplies supplementary information which a teacher could incorporate into the lessons at a simplified level. Outcomes of this unit in physical health are given in terms of the student's (1) awareness of the effects of communicable diseases on human life; (2) appreciation of the progress of man's efforts to control communicable disease; (3) familiarity with conditions under which communicable diseases may be transmitted; (4) knowledge of various methods of protection from communicable diseases; (5) application of desirable personal health practices; (6) understanding of ecological factors related to disease prevalence; and (7) familiarity with the epidemiological method in the prevention and control of disease. Multimedia resources--including books, pamphlets, and films--are included. (SES)
