In 1991, a survey questionnaire concerning undergraduate education in physics was sent to a nationally representative sample of 597 four-year colleges and universities. Of these, 475 had an undergraduate physics department or a department with a physics program, and met the criteria for inclusion in the study. Responses were received from 450 of the 475 eligible institutions. The data were weighted to provide national estimates about instruction staff, computer resources, course offerings, and issues and concerns in undergraduate education in physics. Some of the highlighted results included the following. Three-quarters of 4-year colleges and universities had physics programs. Bachelor's degrees were offered by 79% of the departments with physics programs, 25% offered master's degrees, 17% offered doctorates, and 3% associate's degrees. Slightly over one-fourth of the departments stated that the number of students who declared a major in physics increased in the last 5 years. In evaluating the six components of undergraduate education in physics, department chairs assessed curriculum and faculty/staff resources more positively than they did student preparation and motivation. A large majority (85%) stated they offered undergraduate physics students access to departmental computers for undergraduate research and coursework. (PR)
