Problems of cost stall substantial implementation of computer-assisted instruction, (CAI) particularly for dispersed populations. This paper examines the problems inherent in providing CAI to scattered groups so that accurate estimates of the costs of different technologies (including satellites) which could deliver CAI to dispersed populations…

Computer-assisted instruction (CAI) has become sufficiently widespread to require attention to the relationships between its costs, administration and benefits. Despite difficulties in instituting them, quantifiable cost-effectiveness analyses offer several advantages. They allow educators to specify with precision anticipated instructional loads,…

Any general systems approach has five basic elements, which serve as the tasks for the researcher using systems analysis. The five are (1) the objectives, (2) the alternatives, (3) the costs, (4) the model (or models), and (5) the decision rule. With these five steps, the researcher should be able to specify the objectives, select alternatives,…

A bibliogrpahy of about 4,000 entries was compiled as a first step in assessing the state of the art of the systems approach to training (SAT). It was concluded that the voluminous SAT literature reveals an underlying confusion concerning the nature of SAT. The same terms are used to refer to different methodologies, thereby yielding the illusion…
