The high school teacher is frequently called upon to give instruction in health science, either as an integral part of the biology course, or in some other curricular relationship. More than ever before in American history, the present high school student faces the prospect of someday living in a foreign country and facing whatever health problems may be involved. Military service, employment under technical assistance programs, or connection with various commercial and industrial enterprises are common experiences today, in addition to student exchange arrangements and educational or recreational tours. What preparation is the adolescent now receiving that will (1) make him continually conscious of the health hazards in a tropical or unsanitated area? (2) equip him with the knowledge necessary for taking intelligent, personal precautions? (3) give him some knowledge of health organization on a world basis, in order that he may know where to turn for guidance and information in a particular situation or geographical area? I became acutely concerned with this problem a few years ago, in connection with summer teaching of high school faculty personnel. It was apparent that content of high school courses is inevitably weighted in the direction of the teacher's previous preparation, and it 'seemed evident that a real lack of preparation in certain aspects of health science was almost ,universal. Under a Faculty Research Fellowship, I -'vas able to conduct an investigation into the literature most likely to influence the teacher (of high school science during his preparatory years. Three classes of health literature were :scrutinized. 1. Health textbooks used directly or indi-rectly in connection with courses intended for ;all college students. These are usually taught at the junior college level under such titles as Effective Living; Personal Living; Healthful Living; or Personal Hygiene. 2. Textbooks and other documents used in connectton with courses in Health Education. Such courses are usually offered at the senior college level and are taken principally by candidates for teaching credentials. 3. Theses and term papers prepared by inservice teachers for graduate or certificate credit and filed as library material. Titles of these items are particularly useful indicators of the direction in which the health interests of active teachers have been slanted, either by instruction received or through community experience.
