"The school, as one of the significant agencies of the community, accepts its responsibilities for contributing to individual to individual, family, and community health. ...Classroom teachers in their daily contacts with boys and girls are the key persons in the school health program." These two sentences point up the theme of this bulletin. Four phases of the school health program are discussed briefly and simply: (1) School Health Services; (2) Health School Environment; (3) Healthful School Living, and (4) Health Instruction. The teacher's part in each is emphasized, but consideration is also given to contributions that can be made by other school and health personnel, parents, the community, and the children themselves. The child is the focal point of most of the discussions. The bulletin takes seriously the question: Within the framework of a total school program of elementary education, what kinds of experiences help boys and girls to maintain or improve physical, mental, emotional and social health. The bulletin is written primarily for prospective teachers and teachers in service. However, other persons--school administrators, health coordinators, supervisors, faculty members of teacher-education institutions, pubic health personnel or parents, and other interested citizens--should find useful information and suggestions. This bulletin contains the following: (1) The Teacher's Responsibility in Health Services; (2) The Teacher Looks at a Healthful School Environment; (3) Healthful School Living; (4) Important Factors in Health Instruction; and (5) Other Matters for Teacher Consideration. A bibliography is included. (Contains 7 footnotes.) [Best copy available has been provided.]
