A Formal Assessment of the Haptic Paddle as a Teaching Tool in System DynamicsIn this paper, we present a formal assessment of the haptic paddle, a one degree of freedomforce-feedback joystick that has been adopted at several universities as a teaching tool inSystem Dynamics. System Dynamics is a core mechanical engineering undergraduate coursethat requires students to combine their knowledge from physics and differential equations tomodel dynamic systems in several domains. Gaining an intuitive understanding of the coreconcepts in this course is often difficult for students, particularly when they lack interactionwith a real physical system. The haptic paddle is an ideal platform to address this issue as itcontains all of the core components of a simple dynamic system, which students analyze andmodel throughout the semester, while also enabling students to interact with and physically“feel” the behavior of several virtual dynamic systems. Further, prior qualitativeassessments of the device have shown that both students and educators find it beneficial inconveying the core concepts of the course.In order to complement these previous qualitative assessments, which contained mostlyopen ended questions, we have conducted a systematic assessment of the haptic paddlelaboratories in order to provide a more formal insight into their learning benefits. Weadministered a 25 question quiz at the beginning of the semester to assess students’ initialunderstanding of the course material. This multiple choice question quiz, separated into setsof 5 questions for each of the 5 laboratories, covered the core concepts in each laboratory.Throughout the semester, we administered the appropriate 5 question quiz to each of ourfour different laboratory sections, randomizing presentation at (1) the beginning of a labsession, (2) after a pre-lab lecture, (3) after completing the lab, and (4) after completing thelab report. This assessment architecture enables us to assess the lab and lecture componentsindependently, providing insight into whether and when student learning occurs. Analysis of2 years of data will be presented, followed by a discussion of future planned improvementsfor the laboratories based on the assessment results.
