The Open University, founded in 1969, has already become the largest university in Britain in terms of the number of undergraduate students, with an enrollment of 41,000 in 1973. This paper is concerned with three areas of discussion: (1) the number of teachers studying Open University courses; (2) the courses available or planned in science and technology; and (3) the integrative features of Open University science and technology courses. The survival rate of teachers appears to be marginally higher than that of other occupational groups, with teachers comprising 42 percent of the continuing students in 1972. A chart outlines the courses available in science and technology together with the credit awarded for each course. Many of these courses are multidisciplinary in content, integrative in approach, and relate the subject to the social context. The author concludes that science and technology courses of the type being taught in the Open University could make a significant contribution to the education of teachers of integrated science. (JR)
