Expert Systems as a Mindtool To Facilitate Mental Model Learning.
Mason-Mason, Susan Dale
Expert systems are computer programs that are designed to advise or assist users by storing the knowledge of human experts and applying the computer's mathematical ability to search and sort this information. This study investigated the use of an expert system as a mindtool and whether or not creating a simple expert system would facilitate the formation of an accurate mental model of a system. The domain selected for the study was that of hydraulic brake drums. Participants were 33 adult males and females from a variety of professions located in the United States, Canada, and the United Kingdom. Results indicate that creating the expert system substantially increased participants' scores on all three measures of mental models. In addition, participants indicated that using the expert system focused their attention on the topic and that it was fun to use. Network similarity scores increased significantly, with a large effect size, during the midtest to posttest period during which participants created the expert system. Scores on a test of troubleshooting increased significantly, but with only a medium effect size. Results of a prediction test also indicated that the use of an expert system facilitated the development of more expert-like knowledge structures. Expert systems appear to be versatile and powerful mindtools. (Contains 8 tables, 6 figures, and 59 references.) (SLD)
