Can Implementation of Computers Be Justified on Cost-Effectiveness Grounds.
Shavelson, Richard J.; Winkler, John D.
Claims that computers and other high technology can replace teachers and staff, thereby reducing educational costs, are unwarranted for several reasons. First, most cost analyses focus on hardware costs, which are not the major factor directing the cost of computer assisted instruction (CAI). Second, technology is more likely to change the skill mix of labor in education than to decrease the labor intensity. Third, studies of CAI effectiveness lead to a policy of integrating the computer with the teacher, not replacing the teacher. Finally, the cost of replacing a significant portion of teacher time with CAI is currently prohibitive. This paper includes 19 references. (LMM)
