Progression of mental models throughout the phases of a computer-based instructional simulation: Supportive information, practice, and performance
Students of chemical engineering (n=26) participated in an experiment using a computer-based simulation of a chemical plant. The progression of participants mental models was examined throughout a computer-based instructional experience as they acquired the complex cognitive skills of troubleshooting. Participants mental models of the complex learning task were matched against an expert mental model at five observation points through the instruction. Progressions of learners mental models were examined before and after three phases of the instructional process: supportive information presentation, problem solving practice, and performance test. The results indicated a significant change in participants mental models after receiving the supportive information and little change after practice or performance. This paper presents the results of this investigation and discusses the findings and their implications for computer-based instruction and training.
