Applying Phenomenography to Develop a Comprehensive Understanding of Ethics in Engineering Practice
(IEEE, 2018-10) Brightman, Andrew O.; Fila, Nicholas D.; Hess, Justin L.; Kerr, Alison J.; Kim, Dayoung; Loui, Michael C.; Zoltowski, Carla B.; Technology and Leadership Communication, School of Engineering and Technology
This Work-in-Progress Research paper describes (1) the contemporary research space on ethics education in engineering; (2) our long-term research plan; (3) the theoretical underpinnings of Phase 1 of our research plan (phenomenography); and (4) the design and developmental process of a phenomenographic interview protocol to explore engineers' experiences with ethics. Ethical behavior is a complex phenomenon that is complicated by the institutional and cultural contexts in which it occurs. Engineers also have varied roles and often work in a myriad of capacities that influence their experiences with and understanding of ethics in practice. We are using phenomenography, a qualitative research approach, to explore and categorize the ways engineers experience and understand ethical engineering practice. Specifically, phenomenography will allow us to systematically investigate the range and complexity of ways that engineers experience ethics in professional practice in the health products industry. Phenomenographic data will be obtained through a specialized type of semi-structured interview. Here we introduce the design of our interview protocol and its four sections: Background, Experience, Conceptual, and Summative. We also describe our iterative process for framing questions throughout each section.
Critical Incidents in Engineering Students’ Development of More Comprehensive Ways of Experiencing Innovation
(ASEE, 2018) Fila, Nicholas D.; Hess, Justin L.; Engineering Technology, School of Engineering and Technology
Numerous approaches to fostering the innovative behaviors of engineering students have been explored, especially in recent years. However, often these studies are not qualitatively grounded in students’ experiences with being or becoming innovative. This study builds upon a previous study that explored differences in the ways engineering students understood and experienced innovation. While that study utilized phenomenography to explore variation in ways of experiencing innovation, here we used the Critical Incident Technique (CIT) to explore how engineering students progressed from less to more comprehensive ways of experiencing innovation. We sought to address the research question, “What aspects of engineering students’ innovative experiences were critical to the development of their ways of experiencing innovation?” Through CIT, we identified 122 critical incidents among the 16 interviews. We used thematic analysis to group these incidents into four categories including: Learning From Immersion; Learning from Failure; Learning from Others; and Learning from Success. These categories encapsulated two to three incident types each, or 10 incident types total. Further, we utilized these findings to begin exploring trends in how critical incidents informed participants’ ways of experiencing innovation. These findings detail critical components for promoting students’ novel or more comprehensive understandings of and approaches to innovation that other engineering educators may utilize in their own courses and curricula. Importantly, we recognize that these findings are not exhaustive and future studies are to elaborate upon the the incident types and trend identified herein, and explore if and how these findings can translate to other populations.
Deepwater Horizon Oil Spill: An Ethics Case Study in Environmental Engineering
(American Society for Engineering Education, 2016-06) Beever, Jonathan; Hess, Justin L.; Office of the Vice Chancellor for Research
The April 20, 2010 Deepwater Horizon oil rig explosion was an engineering and environmental tragedy that led to the loss of 11 human lives and has had far-reaching environmental and economic impacts, the full extent of which is difficult if not impossible to calculate. In 2015 the explosion continues to impact those 11 individual’s families; it continues to have a far-reaching emotional impact on the 115 men and women on board at the time of the catastrophe; scientists are still evaluating the environmental impacts of both the oil dispersion throughout the gulf and the oil dispersant used to curtail the spill at surface depths. Simultaneously, gulf business owners, particularly those who rely on gulf waters for their livelihoods, continue to struggle. This novel and far-reaching real-world disaster is particularly salient for use within engineering curricula due to its inherently complex interplay of ethical issues and the broad scope of stakeholders impacted by the initial disaster and its aftermath. We have developed and refined this real-world case study with students participating in a graduate level course at Purdue University over three separate years and five course offerings. We designed this case study within a unique pedagogical framework that leads students to reflectively adopt varying stakeholders’ perspectives in order to reason through the case within a team setting. As a final goal, students must decide the appropriateness of continuing deepwater drilling throughout the Gulf of Mexico in light of the human, economic, environmental, and social implications of future potential blowouts. As part of the broader ethics course in which this case is embedded, we selected this case as it provides a uniquely broader scope of stakeholders and a more specific focus on the principles of nonmaleficence and justice when compared to the other cases presented to students. Specifically, this case asks students to consider a broad range of stakeholders. Whereas many engineering ethics case studies focus on human stakeholders and corporations, here the focus also includes marine and aquatic life, challenging a narrowly anthropocentric focus by placing environmental issues as a focal point. In this sense, our focus pushes beyond other case studies in ethics by addressing both macro-ethical issues, where students are encouraged to adopt a broadened societal viewpoint to deduce the most ethical courses of action, and micro-ethical issues, where the focus is towards the professional obligations of an individual engineer, through a scaffolded staged pedagogy. In this paper we present the case structure and pedagogy to argue for the relevance of this unique, novel, and effective case for increasing engineering students’ ethical reasoning abilities, particularly broadening their awareness of the scope of stakeholders impacted by engineering decisions and their ability to empathize with those stakeholders.
Developing an understanding of the implementation and impacts of high school pre-engineering programs: Making the case for a benefit-cost analysis
(IEEE, 2017-10) Sorge, Brandon; Hess, Justin L.; Technology and Leadership Communication, School of Engineering and Technology
With the ongoing demand for improved K-12 STEM education, a push for dual-credit courses, and the goal of college and career-ready high school graduates, schools have implemented numerous STEM programs including those focused on engineering. Curricular programs, such Engineering by Design, Project Lead the Way (PLTW), and EPICS High are being executed by schools across the country with varied amounts of success as measured by student-level outcomes. Exploring costs of these program implementations and their associated outcomes is vital in deciding the best means for preparing our future engineering workforce. This paper utilizes cost analysis to provide initial insights into the relative impact of one of the most common high school engineering program, PLTW. Specifically, by relying on data reported in select literature, we investigate the impacts versus the costs of implementing PLTW in high schools. Cost data includes select variables such as student section size, school size, and school type. These findings will provide a baseline for understanding cost variations of the PLTW curriculum across contexts, as well as what impact cost variations may have on student outcomes.

The Development and Growth of Empathy Among Engineering Students
(American Society for Engineering Education, 2016-06) Hess, Justin L.; Fila, Nicholas D.; Department of Engineering Technology, School of Engineering and Technology
Discourse on empathy is growing globally, as is its focus within the engineering community. In the context of engineering, scholars have depicted this interpersonal phenomenon as a necessary skill for effectively communicating, a core component of ethical reasoning, and a key technique for designing to meet the needs of users. However, literature regarding its development within engineering is rather limited, and the literature that does exist is disconnected. Even literature outside of engineering tends to focus on childhood development as opposed to adult development. While the developmental literature may tend to focus on earlier ages (likely because this is when an individual most rapidly develops), the endeavor of empathic growth and development need not be abandoned within post-secondary education. Rather, it indicates that we lack an understanding of the ideal means for empathic development later in one’s life. Given the growing emphasis on the necessity of empathy to thrive as an engineer, engineering educators need to understand the constellation of existing tools and pedagogical techniques to foster empathy within the engineering curriculum. This synthesis piece highlights a variety of educational contexts and pedagogical techniques, each of which we posit are equally salient and mutually supportive for the development of engineering students’ empathic skills, abilities, or dispositions. We draw from literature from a wide variety of fields, including counselling, psychology, moral philosophy, psychotherapy, neuropsychology, and engineering education. In sum, we describe five educational contexts and a myriad of techniques that we posit, when used effectively and spread across engineering curricula, will be effective means towards the development of empathy among engineering students.
The Development of Ethical Reasoning: A Comparison of Online versus Hybrid Delivery Modes of Ethics Instruction
(a, 2016-06) Hess, Justin L.; Kisselburgh, Lorraine G.; Zoltowski, Carla B.; Brightman, Andrew O.; Department of Engineering Technology, School of Engineering and Technology
There is a concerted effort to improve online learning opportunities in higher education, including in the domain of engineering ethics. The benefits of online learning include ease in sharing course content, flexibility in the timing of participation, and increased variation in delivery modes for course material. However, the effect of online and hybrid participation on developing ethical reasoning in students is largely unknown, and interactive cases and dialogic learning are central to the pedagogy in ethics courses. An opportunity to fill this knowledge gap occurred while testing a new pedagogy for enhancing ethical reasoning among engineering graduate students, implemented in a graduate-level course over three offerings in Spring 2014, Summer 2014, and Spring 2015. Of the 29 students enrolled, 11 participated on-campus in a weekly class discussion-based lecture, and 18 completed the majority of course activities online. This multi-phase study presents results from a comparative analysis of the differences in ethical reasoning development and perception of course activities across these groups. Both groups of students showed substantial gains in their ethical reasoning development. Furthermore, changes in ethical reasoning were not significantly different when students participated in the on-line only versus an on-line/in-class or “hybrid” format. Nonetheless, analysis from post-course surveys indicated that the hybrid group perceived course activities more favorably than did their on-line only peers. In sum, these results indicate that on-line ethics interventions can be designed to be as impactful in developing ethical reasoning as formats that include an in-class component, although students may be more satisfied with ethics education when they have the opportunity for face-to-face, in-class interaction with peers and instructors.
The Efficacy of Project Lead the Way: A Systematic Literature Review
(American Society for Engineering Education, 2016-06) Hess, Justin L.; Sorge, Brandon; Feldhaus, Charles; Department of Technology and Leadership Communication, School of Engineering and Technology
Project Lead the Way (PLTW) is a non-profit organization offering project-based STEM education curricula for K-12 students. As of 2015, PLTW was by far the largest pre-engineering program implemented throughout the United States with a presence in over 6500 schools. Since its conception in 1997, PLTW rapidly expanded and today covers all 50 states and the District of Columbia. The PLTW Engineering curriculum offers a sequence of courses that students may take over the course of high school, and many university programs allow students who complete this sequence the opportunity to earn college credit. The PLTW Gateway curriculum targets students in Grades 6-8 and the PLTW Launch curriculum targets K-5 students. See the PLTW website for current program titles. They now simply use PLTW Engineering, PLTW Gateway and PLTW Launch. This study investigates the efficacy of PLTW efforts through a systematic literature review process. Specifically, we explored the following research questions: • To what extent has PLTW been an area of scholarly investigation and what has been the nature of these investigations? • What primary strengths and weaknesses of PLTW have these investigations identified? • What gaps in PLTW literature exist and what future research is needed? After an initial data collection and literature reduction processes, we synthesized 31 articles that collected and analyzed empirical data related to PLTW. Our gathered literature included 16 journal articles, 11 dissertations, and 4 theses. Using an emergent coding process, we found that primary strengths of PLTW curricula include motivating students to pursue STEM degrees, providing teachers with professional development opportunities and support, and facilitating student interest in STEM subjects. However, weaknesses of PLTW include minimal evidence supporting PLTW in improving students’ mathematics and science abilities, scheduling and space issues, and moderate financial costs for schools to participate in PLTW. Altogether, the literature collected varied widely and, as a result, each of these strengths and weaknesses requires further investigation. This study concludes with an identification of gaps in PLTW literature that can focus future PLTW-related investigations and, if investigated, help improve future PLTW-related interventions.
Empathy and ethical becoming in biomedical engineering education: A mixed methods study of an animal tissue harvesting laboratory
(Taylor & Francis, 2021) Hess, Justin L.; Miller, Sharon; Higbee, Steven; Fore, Grant A.; Wallace, Joseph; Biomedical Engineering, School of Engineering and Technology
Biomedical engineering presents a unique context for ethics education due to the human-centric nature of biomedical engineering coupled with the pervasiveness of animal-based practices. This study summarises the design of a pedagogical practice intended to enhance students’ abilities to recognise ethical issues in biomedical engineering practice and inquire into normative aspects of the discipline. The context of the study is an introductory biomechanics course wherein students harvested animal tissue, critically reflected on this experience, and discussed the experience in class. We brought two theoretical frameworks to this investigation pertaining to empathy and ethical becoming. We employed a four-phase mixed methods research design that included quantitative comparisons of changes in empathy and related phenomena, thematic analysis of written reflections, an observation and focus group, and triangulation of these results. Quantitative data remained stable before and after the course. Thematic analysis of reflections revealed five themes: research design, treatment of animals, beneficence, worth of life, and emotional engagement. The observational and focus group results emphasise affective considerations of engineering practice. This study provides a guide for future biomedical engineering education efforts that deal with ethically sensitive, emotionally powerful, and visceral experiences, as well as for research pertaining to empathy and ethical becoming.
The Engineering-science Intellectual Property (ESIP) Project: A Novel Method for Promoting Innovation
(ASEE, 2018-06) Piroozi, Hamid R.; Hess, Justin L.; Feldhaus, Charles; Technology and Leadership Communication, School of Engineering and Technology
In the idea economy, intellectual property (IP) is valued higher than other assets such as factories and equipment. Affirmation of this valuation is often observed when a company’s IP advances or declines which causes a seismic shift in its stock price. IP law, however, is complicated and is evolving. As a result, new engineering and science graduates take many years, if ever, before they are familiar with the process of securing IP. Lack of such familiarity often results in IP being an after-thought in design processes. While others have attempted to discuss IP as part of a larger entrepreneurship setting in the form of a brief introduction of various IP vehicles, a solid understanding of what is protectable requires more than familiarity with IP concepts. This paper describes the development and underlying theory of a novel educational program titled Engineering-Science Intellectual Property Project (ESIP-Project). This project includes three degree-counted elective courses that together create an IP concentration in an engineering BS curriculum. The intent of the project is to generate within students a deep understanding of IP requirements for creating novel, nonobvious, and non-infringing designs. In addition, the ESIP-Project is designed to teach IP concepts as they relate to engineering design, as well as critical thinking skills and innovation. More specifically, students will be prepared to engage in prior art review, identify what is needed to obtain enforceable designs, and apply strategies to avoid infringement of existing patents. At the culmination of ESIP-Project, students will be prepared to pass the patent bar examination and become certified to practice patent law before the U.S. Patent and Trademark Office. Hence, graduates of the ESIP-Project will have new career options including choices for becoming patent engineers and patent agents, in addition to traditional technical career choices. This paper includes an overview of the three-course sequence, as well as evaluation results of the implementation of the first course. A survey was designed by the investigators and implemented pre and post course. The survey included three constructs: Knowledge of IP Concepts, Innovative Product Design, and Careers in Patent Law. Following reliability testing procedures, student responses to these constructs were compared before and after course implementation. Despite the small sample size (15 students), comparative analyses suggested students experienced strong, positive gains in each construct. These positive changes in student responses from participation in just one of three IP courses is encouraging to our team. We hope that the ESIP-Project model, and our evaluation of the model as we scale it up, will provide a pathway for other educators to follow, particularly those who are interested in promoting entrepreneurship and innovation among their students.
