Conference PaperDevelopment, Dissemination and Assessment of Inexpensive Miniature Equipment for Interactive Learning of Fluid Mechanics, Heat Transfer and Biomedical ConceptsVan Wie, B.; Durak, Z.; Reynolds, O.; Kaiphanliam, K.; Thiessen, D.; Adesope, O.; Ajeigbe, O.; Khan, A.; Dutta, P.; Curtis, H.; Watson, C.; Gartner, J.As this NSF LCDLM dissemination, development, and assessment project matures going into our fourth year of support we are moving forward in parallel on several fronts. We are developing and testing an injection-molded shell-and-tube heat exchanger for heat transfer concepts, an evaporative cooler to expand to another industrial-based heat exchange system, and a bead separation module to demonstrate principles of fluid mechanics in blood cell separations applications. We are also comparing experimental data for our miniaturized hydraulic loss and venturi meter LCDLMs to predicted values based on standard industrial correlations. As we develop these new learning components, we are assessing differential gains based on gender and ethnicity, as well as how students learn with existing LCDLMs in a virtual mode with online videos compared to an in-person hands-on mode of instruction.2022-08-2310357291ASEE annual conference proceedings1524-4857https://doi.org/1821578National Science Foundation
