Program Description: The Nephrotex virtual internship can be classified as an epistemic game—a computer simulation of a professional practice. The primary objectives of Nephrotex are (1) to offer an alternative first year program that models authentic engineering practices, (2) to give students an opportunity to engage in engineering design and complex problem solving, and thus (3) to motivate students, especially women and underrepresented minorities, to continue in the field of engineering. First year students play the role of interns at a fictitious medical device company and participate in complex problem solving. The instructors and teaching assistants role play as employees of the company. Students are also prompted to learn more about the company, its employees, mission, vision, and history through short assignments that require students to explore the Nephrotex website including creating staff pages. Students go through two complete engineering design-build-test cycles and must select a final optimum prototype at the end of their internship and justify their design decisions by writing reports in their digital engineering notebooks. Students must also try to satisfy stakeholders within the company who have conflicting values, which adds additional complexity to the design problem. In fact, the design of the simulation does not allow for students to create a device that satisfies all the stakeholders’ requests. Thus, each student individually justifies their design selection and explains why he/she chose to meet certain stakeholders’ requests and not others. In addition to the structure of the design exercise and the simulated professional environment, the fact that the simulation is entirely online means that it is broadly accessible to large and small classes, in non-traditional or extension classes, at a broad range of institution types. Faculty, graduate students, and undergraduate students from the College of Engineering and the College of Education were involved in the development, building, and testing of this project. The co-PIs on this project were a professor from the biomedical engineering department and a professor from the educational psychology department (learning sciences area). Two undergraduate students in engineering physics, two undergraduate students in biomedical engineering, and two graduate students in learning sciences were involved in the development and implementation of this program. A mechanical engineering professor, the instructor for the course, also assisted with original implementation.

Anticipated and Actual Outcomes: We implemented Nephrotex in a first year course in which students choose two half-semester modules to study a single topic in engineering in depth; Nephrotex was offered as one possible module, and the other modules involved students working in teams to read and discuss research addressing engineering problems, but did not engage in engineering design. We anticipated the Nephrotex students would learn engineering content, be more motivated to persist in engineering, view engineering more positively, and have a better understanding of what an engineer does compared to students in other modules. We expected that this increase would be more significant for women and that students would be engaging in complex discourse surrounding engineering design and problem solving. The data from fall 2010 support these three claims about the experience of students in Nephrotex. All students in Nephrotex had statistically significant gains in engineering content knowledge related to the design task posed in Nephrotex. Women in Nephrotex had a statistically significant increase in positively viewing engineering careers compared to women in the control group. The more that a student participated in complex engineering design discourse in Nephrotex, the more likely they were to report that they viewed engineering more positively.

Assessment Information: There were two sources of data collected for this analysis: (1) students’ pre- and post-survey responses about perceptions of engineering careers and motivation to persist in engineering and (2) students’ discourse through participation in the chat program. All data was recorded and collected digitally. The discourse data was coded using a set of codes developed from ABET criteria for undergraduate engineering program outcomes and using epistemic frame theory as a guide for professional practices. We used Epistemic network analysis (ENA), which allows measurement of the development of connections students make between skills, knowledge, identity, values, and epistemology of engineering professional practice. This quantification helps us determine if students are engaging in engineering design and solving problems similar to the ways that professional engineers solve problems. We then analyzed these data to investigate whether students were more motivated to pursue engineering after participating in a virtual internship and how students were discussing engineering design problem-solving in the context of the virtual internship. Our research questions for the first implementation of the virtual internship were focused on engineering content learning gains, engagement with the virtual internship, attitudes towards engineering, especially among women, and motivation to continue in engineering.

Funding/Sustainability: Initial funding was provided by an NSF grant of $500,000. The program costs included salaries for PIs, undergraduate students, and graduate students, travel, materials and supplies, and publication costs. We are exploring the idea of pairing with other academic institutions as well as potential industry partners.

The aim of this report is to encourage enhanced richness and relevance of the undergraduate engineering education experience, and thus produce better-prepared and more globally competitive graduates, by providing practical guidance for incorporating real world experience in US engineering programs. The report, a collaborative effort of the National Academy of Engineering (NAE) and Advanced Micro Devices, Inc. (AMD), builds on two NAE reports on The Engineer of 2020 that cited the importance of grounding engineering education in real world experience. This project also aligns with other NAE efforts in engineering education, such as the Grand Challenges of Engineering, Changing the Conversation, and Frontiers of Engineering Education.

This publication presents 29 programs that have successfully infused real world experiences into engineering or engineering technology undergraduate education. The Real World Engineering Education committee acknowledges the vision of AMD in supporting this project, which provides useful exemplars for institutions of higher education who seek model programs for infusing real world experiences in their programs. The NAE selection committee was impressed by the number of institutions committed to grounding their programs in real world experience and by the quality, creativity, and diversity of approaches reflected in the submissions. A call for nominations sent to engineering and engineering technology deans, chairs, and faculty yielded 95 high-quality submissions. Two conditions were required of the nominations: (1) an accredited 4-year undergraduate engineering or engineering technology program was the lead institutions, and (2) the nominated program started operation no later than the fall 2010 semester. Within these broad parameters, nominations ranged from those based on innovations within a single course to enhancements across an entire curriculum or institution.

Infusing Real World Experiences into Engineering Education is intended to provide sufficient information to enable engineering and engineering technology faculty and administrators to assess and adapt effective, innovative models of programs to their own institution's objectives. Recognizing that change is rarely trivial, the project included a brief survey of selected engineering deans concern in the adoption of such programs.
