Development of Hands-on Desktop Learning Modules for Bioengineering Courses – A Work in ProgressAbstractCurrent engineering courses heavily rely on traditional lectures to cover engineering concepts.The engineering education community, however, recognizes that this is not the best method forteaching engineering material. Our team has focused on expanding the use of well researched,though still new to engineering, teaching pedagogies of cooperative, hands-on, active, andproblem-based learning through the development of Desktop Learning Modules (DLMs).The DLMs contain miniaturized processes, such as a boiler/condenser (chemical engineering),and hydraulic flow channels (civil engineering). A unique expandable electronic system withinthe DLM connects with known sensor systems, allowing cartridges to be interchanged. We areexpanding applications by creating new cartridges for teaching bioengineering concepts.One such cartridge will model cell separations that result through sedimentation, particularly as itapplies to the separation of prostate circulating tumor cells (PCTCs) within human blood. Forthis, a funnel shaped elutriator containing millimeter-sized polymer particles of variable size anddensity will be used to mimic hindered settling and help students understand concepts related toseparation of PCTCs from white blood cells.The cell separations DLM will be implemented into a biomedical engineering course in the 2013spring semester. Students will be interviewed prior to implementation to identify misconceptionspertaining to hindered settling and to outline the experimental design for assessing the impact ofthe DLM on learning. The assessment will include concept tests before and after using the DLMto determine improvement in understanding basic concepts and persistence and/or repair ofmisconceptions.A physical model of the cell separations DLM and preliminary classroom assessment data willbe presented at the 2013 ASEE Meeting as a “work in progress,” Future work will includedevelopment and implementation of cell sensor and thermoregulation cartridges.
