The report of the third year of Harvard's Program on Technology and Society contains summaries of research done on the relationship of technology to education, biomedical science, business, and social and political change in general. The research group on education, concentrating on secondary education, concluded that high schools in ten years are unlikely to be very different from present ones--in respect either to effective utilization of educational technology or successful preparation of youth for a technological society. On the other hand, it appears that the implications of discovery in biomedical sciences will be potentially spectacular in ten years, affecting such problems as the organization of health care, the process of aging, and control of human behavior. The challenge to business will be to convert the traditional market competition into a mechanism capable, as not heretofore, of fulfilling social needs. The ability of technology to provoke social and political change, and its enhancement of social knowledge is discussed. A review of all research projects and a list of publications is included. (BB)
