Recent data suggests that a little more than half of students who start in an engineering program leave after the first or second year and that many of those students came to dislike engineering or lost interest in the profession. These findings indicate a potential mismatch between what incoming students think engineering practice is and what message they receive during their first two years of a program. Unlike the other major professions with which engineering shares a common set of principles (e.g., medicine and law), there are very few examples of engineering in popular American culture, and fewer still that are realistic. Thus, a limited number of studies have considered the impacts of exposing students to the history of the profession on students’ perceptions of engineering practice. The overall aim of this project is to understand how historical contextualization of what it means to practice engineering can improve students’ intentions to persist in a discipline that historically struggles to retain them, particularly those identifying as underrepresented minorities and women. With this understanding, changes can be made to undergraduate engineering education to better retain students. A secondary aim is to contribute new knowledge about students’ understanding of what it means to practice engineering and how that understanding changes with additional context for the careers for which they are preparing. This work provides second year mechanical engineering students with a more holistic contextualization of engineering practice by introducing them to the history of the profession. This work aims to advance the field of engineering education research by studying how students’ perceptions of engineering practice develop as they progress through a program, and how this activity can shape that progress and/or reframe their beliefs about their education and training. For example, students are educated about how the Morrill Land Grant Acts were essential to the growth of engineering at higher education institutions, but at the considerable cost of indigenous peoples who were forcibly removed from the lands provided to those institutions. Additionally, students are educated about the differences between professions and occupations, and how their technical competence is intimately connected with their ability to make ethical engineering decisions. Planned semi-structured will reveal how students’ perceptions of engineering practice change longitudinally and whether the aforementioned educational activity influences that trajectory. 

Engineering programs have long struggled with balancing curricula that are rigorous enough to prepare graduates to be capable practitioners and educational experiences that are engaging enough to retain undergraduate students. Over the past 60 years, data collected from a variety of institutions across the United States capture an alarming trend – only about half of students who start in an engineering program will actually graduate with an engineering degree. Several studies found that the first-year engineering curricula, which traditionally consist of physics, chemistry, and mathematics courses, are ineffective in motivating students to persist in a program. Many students who leave after their first or second year explain that they came to dislike engineering or lost interest in the profession altogether. Together, these findings suggest a mismatch between what incoming students think engineering is and what message they receive during their first two years of a program. To address retention issues in the first year of an engineering program, many institutions now employ a first-year design experience intended to expose students early on to the true nature of engineering [4]. However, the engineering science courses that occupy a significant proportion of the middle two years of a program still most often utilize traditional lecture-based pedagogy and simplified close-ended textbook problems, which do not typically allow students to make the connection between these classes and the engineering design process or the engineering profession. These types of closed-ended problems also do not provide students with the opportunity to engage in the kind of decision-making that leads to developing sound engineering judgement. Recent work developing and studying the effects of open- ended modeling problems define an opportunity to provide students with challenging problems that simultaneously reinforce their understanding of course material and expose them to the realities of engineering practice. This NSF-funded work proposes introducing two different pedagogies into a Mechanical Engineering program at the University of Iowa. The first pedagogy is designed to provide a more holistic contextualization of engineering practice by introducing students to the history of the profession. The second instructional technique is intended to provide students with context for how engineering science concepts are implemented in authentic engineering practice and how engineering judgement is essential in that implementation. This work will aim to understand how historical and/or technical contextualization of what it means to practice engineering can influence the intentions of students, particularly those identifying as underrepresented minorities and women, to persist in a discipline that historically struggles to retain them. With this understanding, changes can be made to undergraduate engineering education to better retain students.
