McCarthy, James E., Banta, H. George, Pacheco, Stephen, Scroggins, Roberta and Coleman, David S. (1995): A Prototypical Power Industry Intelligent Training Aid. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. p. 937.

“Once the playthings of researchers, Intelligent Tutoring Systems (ITSs) are now making themselves felt in industry. Nowhere is this trend more noticeable than in the power industry. For example, South Carolina Electric and Gas estimated that adding an ITS developed by the Electric Power Research Institute would result in a 25% increase in efficiency and availability over that seen with a simulator alone (Fray, 1995). This poster describes a prototype ITS that we developed to explore and demonstrate the power of this new training force. The system we developed provides each student with a student sensitive "tutor-in-a-box". Unlike conventional CBT systems that make instructional decisions at design-time, our ITS uses the "tutor" to make such decisions at run-time. For each student, the tutor determines the best order in which to present curriculum topics. It also determines the most appropriate media mix for each student. The prototype includes a simulation of a pressurizer system (typical of pressurized water nuclear reactors). The tutor is used to assess and coach each student as they interact with the simulation. An ITS can increase instructional efficiency in many ways. It can increase throughput, increase retention, increase transfer of training, decrease training time and decrease cost. In addition, Intelligent Training leaves behind an "audit trail" of each student's training experiences and performance. This history could have important regulatory significance.”
