Comparing the Cost-Effectiveness of Tutoring and Computer-Based Instruction
Richard P. Niemiec, Melanie F. Sikorski, Herbert J. Walberg · Journal of Educational Computing Research · 1989
This study combines meta-analytic and costing techniques to investigate the cost-effectiveness of CAI and tutoring. Using many estimates of costs and effects to yield widely generalizable cost-effectiveness ratios (CERs), it appears that CAI is considerably more cost-effective than tutoring. In fact, CAI may be as much as three times more cost-effective than tutoring.
