This paper presents findings from a research project that examined college students' mental models during the execution of an electronic spreadsheet activity. This study has demonstrated the feasibility of stimulated recall methodology for throwing light on the functions of students' mental models with respect to previous knowledge, novices' mental models, cognitive overload, working memory, and chunking. The findings revealed that, at least in this study, mental models plays a critical role in the selection, or failure to select, appropriate strategies.. A comparison of differences in the way mental models were presented by novices compared with advanced students helped identify the kinds of misconceptions that affect the performance of novice students.
