The purpose of this research is to identify differences in the proficiency of students who learned how to construct a circuit on a breadboard under three different levels of physical fidelity – a 2D simulation, a virtual environment and a physical environment. In a previous study, the researchers identified differences in proficiency, defined by construction time, diagram accuracy, and correct circuit construction among participants in the three conditions. However, while providing valuable data about the outcomes achieved by the participants, the results of the study offered little insight into the processes or mechanisms through which the physical fidelity impacted the results obtained. In this follow-up study, we seek to evaluate why students demonstrated significant differences in proficiency between conditions and how these differences related to the fidelity. Semi-structured interviews and video analysis of the participants completing the tasks are used to examine differences in the approach taken by participants, their troubleshooting strategy, and their overall effort and persistence on the task. A visual and verbal elicitation method is used to elicit the mental model of participants as it relates to the circuit construction task and the requisite knowledge. A purposeful sample of 24 participants (from the larger initial study) was recruited for interviews and video analysis. Analysis involves coding the data and generating themes and development and comparison of mental models. The findings of this study will provide valuable insights about how the physical fidelity shapes student’s knowledge structure and allow instructors to better design and integrate these computer mediated environments in technical education.
