Abstract
Recent surveys of school applications of computers show that in contradiction to early expectations, the availability of microcomputers in schools does not have substantial impact on traditional teaching. In this article we identify conditions necessary for teachers to adopt changes in their instruction, and specifically to adopt technological innovations. We argue that the CAI—the use of computers for individualized learning or drill and practice—which is the most common application of computers for teaching and learning, does not satisfy most conditions necessary for teacher adoption. This may explain why the “microcomputer revolution” has not materialized. Finally, we suggest another type of microcomputer applications: Computer-Guided-Teaching, which satisfies most conditions for wide adoption by teachers, and which has potential for substantial teaching improvement.
