Conceptualizations concerning role changes of classroom teachers due to the use of computer assisted instruction (CAI) are contingent upon what system is used and how long it takes. However, some factors within CAI which may cause teacher role changes can be identified. Also, it is likely that the pattern of computer development will be gradual, culminating in a new form of individualization due to the availability of advanced computers and multimedia resources and to the differentiation of staffing. The teacher's role, then, can potentially change toward involving more strategizing, managing, individual counseling, discussing, specializing, and diagnosing functions; and fewer correcting, lecturing, and disciplining functions. Future teacher education programs should feature CAI and prepare teachers for these new roles. (SP)
