New Hands-on Fluid Mechanics Cartridges and Pedagogical AssessmentIn the sciences and engineering, effectively communicating conceptions and fundamental ideasto students is difficult with traditional teaching methodologies. Demonstration mode teachingpedagogy has been used to address this problem, which in this study is applied to fluidmechanics in the chemical engineering discipline. We designed two miniature devices, withclear viewing windows, that snap in to a base unit that is used to modulate flow rates and displaypressure drops. One device is used for measuring pressure drop with fluid flow through a straightpipe, shallow bend, and a 90-degree miter bend; the other is a venturi meter. These devices willbe tested in a within-design study in an undergraduate Fluid Mechanics and Heat Transfer class.Twenty four students will serve as a control group for a first set of concepts taught throughlecture, while 24 will receive a mini orientation-lecture, participate in a guided viewing of thedevice in action using a document camera, and complete a worksheet in groups to process thematerial content. For the second set of concepts the two groups will be switched. Classroomactivities are designed around instructor knowledge of misconceptions and a small set ofinformal interviews. Pre and post concept-tests will be used to measure differences between thecontrol and experimental groups. The experimental group is expected to gain a betterunderstanding of the fundamental concepts and preliminary results will be reported in this paperwith more detailed results in the ASEE presentation.
