software and were able to justify the strategies they used during the experimental lab.As in the Johnson study17, the graduate students were instructed to build the part shown in Figure2, with half of the class instructed to model based on speed and efficiency and the remaining halfof the class instructed to build a robust, flexible model that would accommodate design changes.Students were given one hour to complete the initial model, and completion times were recorded.In the second part of the lab, the students were asked to make design changes as shown in Figure8. Unlike the Johnson study20-23, the second phase of the lab utilized parts that were modeled bythe instructor rather than models created by their peers. Half of the students in each
