Data for the Oregon Microcomputer Survey were collected in May 1989 via questionnaires for each of the department heads in a stratified random sample of 94 middle and high schools throughout Oregon. Designed to obtain information on the perceptions and reactions of the department heads to the status of microcomputers in their departments, the 52-item questionnaires were sent to the principals of the target schools for distribution to the departments of art/music, business education, English/language arts, foreign languages, health/physical education, mathematics, science, social studies, special education, and vocational education. The response rate was 59%. The questionnaires were divided into questions of a general nature, questions about teacher training, questions about computer hardware and software, and questions about computer use. Topics addressed by the survey included the issue of teacher training; hardware and software; instructional effectiveness; department heads' personal involvement; future of computers in instruction; current practices in classrooms; and top problems to solve. Forty-one tables and 29 graphs display the findings on such topics as formal teacher training; hours per week computers are used; student time on computers; computer literacy requirements for certification; repair of computers; advantages for students with special needs; effects of computer use; reasons programs are not being used; types of computers; who should get training; most important influence; unused programs; teacher and student complaints; and a prioritized list of top problems identified by the survey respondents.
