In 1991, a survey questionnaire concerning undergraduate education in geology was sent to a nationally representative sample of 597 four-year colleges and universities. Of these, 275 had an undergraduate geology department or a department with a geology program, and met the criteria for inclusion in the study. Responses were received from 262 of the 275 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 geology. Some of the highlighted results included the following. Almost all research universities (92%) had geology programs, but only 68% of doctoral institutions and much smaller portions of comprehensive (40%) and liberal arts institutions (15%) offered geology programs. Bachelor's degrees were offered by 88% of the departments with geology programs, 42% offered master's degrees, 23% offered doctorates, and 3% associate's degrees. Almost two-thirds (63%) of the departments stated that the number of students who declared a major in geology increased in the last 5 years. In evaluating the six components of undergraduate education in geology, department chairs assessed curriculum and faculty/staff resources more positively than they did laboratory equipment for undergraduate instruction, facilities, student preparation, and teaching assistants. A large majority (80%) stated they offered undergraduate geology students access to departmental computers for undergraduate research and coursework. (PR)
