The problems existent within the built environment are inherently complex due to the interactions between different stakeholders, structures, and systems. The reductionist approach vastly utilized by engineers is not appropriate for dealing with this complexity. Engineers need to be trained to think in systems in order to fully explore the design problem space and therefore identify appropriate design solutions. The study here presented investigates the possibility of the use of concept mapping as an intervention to prime engineering students to think in systems. In the study, 66 engineering students were given two problem framing tasks. Half of the sample received the priming intervention before each task. The control and the intervention group were compared across different metrics. The time spent on the task and length of responses were used as measures of cognitive effort. The number of systems mentioned and the semantic distance between words used in each response were the metrics used for exploration of the design space. Results of the analysis for one of the tasks were significant. The findings suggest that the participants who received the concept mapping priming intervention were able to sustain cognitive effort longer and explore a wider design problem space. / Master of Science / The problems existent within the built environment present interdependencies that need to be identified before suitable solutions can be designed. Engineers need to be able to identify and understand these complex relationships. However, engineers are instead trained and prompted to apply a reductionist approach to problem solving, which isolates parts of a system in order to reduce complexity and facilitate the design process. Concept maps, a graphical tool utilized to display the relationships between concepts and ideas in a hierarchical form, could be used to assist engineers on applying a more holistic approach to problem solving. This research investigates if concept mapping activities can affect engineering students' ability to think in systems and consider all the variables behind a design problem. Participants in the study had to identify and describe everything that could be improved about two different systems familiar to Virginia Tech students. Half of the participants were asked to draw a concept map about each system before each task. All responses were compared between the group that did the concept mapping activity and the group that did not do it. The length in time and words of the responses, the number of systems mentioned, and the originality of the words used by each participant were the metrics utilized to compare the groups. Results suggest that concept mapping can be used as a tool to assist engineering students explore the design problem space more fully.
