At the end of a four-year undergraduate program, it is often difficult to capture the knowledge of the graduating students. The use of mental models, specifically concept maps, can aid in the assessment of this knowledge at a conceptual level. Concept maps provide a visual representation of conceptual and relationship knowledge within a particular domain. Students in a senior-level, undergraduate class were given an assignment of creating conceptual maps of Information Systems. These maps were coded and analyzed for their “coverage” or conceptualization of the sub-field of Telecommunications. The analysis included both quantitative and qualitative assessments as well as comparisons across students’ maps. Preliminary assessments have indicated that there is a fairly large degree of overlap between maps, though a full analysis is not yet complete
