Student modeling--the task of building dynamic models of student ability--is fraught with uncertainty, caused by such factors as multiple sources of student errors, careless errors and lucky guesses, learning and forgetting. Within the context of the Sherlock intelligent tutoring systems project, we have been experimenting with various ways of…

A study found that the troubleshooting abilities of a treatment group of college students trained conventionally in a course called Aircraft Systems II and on a computer-based "Technical Troubleshooting Tutor" were better in some ways than those of a control group who trained conventionally without using the computer-based tutor. Aviation students…

This study examines the effect of the "Technical Troubleshooting Tutor," a computer-coached training program, on aircraft electrical system troubleshooting. Performance ability differences between control groups are noted, and troubleshooting models and flow diagram examples are included. The study demonstrates the possibilities for…
