Modeling Session: Transport of Equipment
Participants were provided with the task to model the “Transport of Equipment” process from a natural language description. Three variants of the task description were created: A depth ﬁrst description, a breadth ﬁrst description and a random description. To ensure that each description is understandable and can be modeled in the available amount of time, we conducted a pre-test with 14 graduate students at the University of Innsbruck. Based on their feedback, the modeling task descriptions were reﬁned in several iterations. The experiment was conducted at two distinct, subsequent events. The ﬁrst event took place early November 2009 at Humboldt Universität zu Berlin, the second was performed a few days later at Technical University Eindhoven. The modeling session started with a demographic survey and was followed by a modeling tool tutorial in which the basic functionality of Cheetah Experimental Platform were explained to our subjects. This was followed by the actual modeling task in which the students had to model the “Transport of Equipment” process. Roughly a third of the students were randomly assigned to the depth first variant of the modeling task, another third to the breadth first variant and the remaining third to the random variant. After completing the modeling task, the students received a questionnaire on cognitive load.
