The findings of research on computers and teaching are reviewed in this monograph, both to provide useful guidelines for teachers, and to serve as a reference point for further research. Research results are organized around the following topics: (1) computer availability and use; (2) classroom applications--computer assisted instruction, computer managed instruction, testing and recordkeeping, and instructional games; (3) curricular applications--language arts, mathematics, science, and social studies; (4) exceptional children; (5) attitude and motivation; (6) large computer systems--PLATO and TICCIT; and (7) future issues and concerns--the videodisc, software (quality control and software protection), quality of research, relationship with industry, networking, teacher training, and effect on formal education. A concluding statement briefly discusses some advantages of and problems with computer use, and an 85-item bibliography is provided. (LMM)
