Nephrotex: A Professional Practice Simulation for Engaging, Educating, and Assessing Undergraduate Engineers Lead Institution: University of Wisconsin-Madison, Madison, WI Collaborating Institutions: University of Pennsylvania Category: First Year Date Implemented: August 2010 Website: epistemicgames.org Program Description: The Nephrotex virtual internship can be engage in engineering design. We anticipated the Nephrotex classified as an epistemic game--a computer simulation of a students would learn engineering content, be more motivated to professional practice. The primary objectives of Nephrotex are persist in engineering, view engineering more positively, and (1) to offer an alternative first year program that models have a better understanding of what an engineer does compared authentic engineering practices, (2) to give students an opportu- to students in other modules. We expected that this increase nity to engage in engineering design and complex problem would be more significant for women and that students would solving, and thus (3) to motivate students, especially women be engaging in complex discourse surrounding engineering and underrepresented minorities, to continue in the field of design and problem solving.
