Ethics has long been recognized as crucial to responsible engineering, but the increasingly globalized environments present challenges to effective engineering ethics training. This paper is part of a larger research project that aims to examine the effects of culture and education on ethics training in undergraduate engineering students at universities in the United States, China, and the Netherlands. We are interested in how students’ curricular and extra-curricular (e.g., internships, service projects) experiences and training impact their ethical reasoning and moral dispositions, and how this differs cross-culturally. To understand this, we are conducting mixed methods research longitudinally over four years to engineering students at our participating universities to gauge their moral dispositions and ethical reasoning skills and to measure any change in these. This work-in-progress paper, however, is not about the direct outcomes of this research project. Rather, it critically examines our own practices and methods in doing this research. We begin the paper by briefly introducing the larger research project and motivating the use of comparative, multi-institutional case studies as necessary for contextualizing, complementing, and interpreting quantitative data on ethical reasoning and moral dispositions. Because the conditions related to engineering ethics education differ widely per participating institution for institutional (and also likely cultural) reasons, interpreting and analyzing quantitative survey data will require understanding contextual conditions of education at each institution. Comparative case studies can supply missing contextual information to provide a more complete picture of the engineering ethics educational contexts, strategies, and practices at each of the participating universities. However, in considering how to design and conduct these case studies, we realized we were operating under certain assumptions such as ethics in engineering as separate (and separable from) the “real,” or technical engineering curriculum. These assumptions have been widely problematized in engineering ethics education (Cech, 2014; Tormey et al. 2015; Polmear et al. 2019); they are assumptions that we in our teaching and research attempt to dispel. Our paper considers (and invites discussion on) the broader implications of methodological design in conducting cross-cultural multi-sited case studies in engineering ethics education research. It explores models for designing and conducting our case studies so as not to reproduce pernicious ideas about social and ethical issues in engineering as subsidiary “interventions” in the “actual,” (i.e., technical) curriculum. More generally we discuss how engineering ethics education research methods can be harnessed to overcome this established division. 

This paper describes a project to develop, deliver, and assess a short-term (one-week) course on global engineering ethics at Shandong University, Shandong, China in the summer of 2022. This project builds on previous work regarding the development and assessment of global engineering ethics, shortening the time required to deliver and assess a course. The goal was to explore whether a shorter version of the course resulted in gains similar to the longer version, and whether shorter versions of the assessment instruments could track these gains. Ethics is increasingly recognized as central to engineering, although disagreement exists concerning how it should be carried out and assessed. These disagreements are compounded by the global nature of engineering, where technologies span multiple countries, and peoples from different cultures work together as never before. Separation in time and space between those developing technologies and those affected by these technologies can increase difficulties associated with identifying and mitigating the negative effects of technology on human life. Additionally, regulatory and cultural differences can lead to disagreement regarding how technologies should or should not be developed and used. For these reasons, efforts have been made to develop global engineering ethics education. Over several years, members of the team have developed and delivered a semester-long, two-credit hour course in global engineering ethics, finding that participants scored significantly higher in measures of ethical reasoning post- than pre-course, and developed a greater concern with fairness and loyalty. Given the limited time and space in engineering curricula, and limited number of qualified faculty to teach global engineering ethics, this project sought to determine whether a course with reduced contents delivered over a shorter period of time would be similarly effective. Additionally, it sought to determine whether shorter versions of the instruments used to assess this education, the ESIT (Engineering and Science Issues Test) and MFQ (Moral Foundations Theory), would be as effective as their original, longer versions. This was motivated by the fact that, in ongoing research, the project team was having difficulty collecting adequate sample sizes, in part because it was taking so long to complete full versions of the ESIT and MFQ. To do so, in July of 2022, Chinese students enrolled in “Global Engineering Ethics” completed shortened versions of the ESIT and MFQ on the first and last days of the course. Our presentation will describe the nature of the course, as well as pre- and post-course results on shortened versions of the ESIT and MFQ. 

In the engineering ethics education literature, there has recently been increasing interest in longitudinal studies of engineering students’ moral development. Understanding how first-year engineering students perceive ethics can provide baseline information critical for understanding their moral development during their subsequent journey in engineering learning. Existing studies have mainly examined how first-year engineering students perceive the structure and elements of ethics curricula, pregiven ethics scenarios, what personal ethical beliefs and specific political ideals they hold (e.g., fairness and political involvement), and institutional ethical climates. Complementary to existing studies, our project surveyed how first-year engineering students perceive professional ethical values. Specifically, we asked students to list the three most important values for defining a good engineer. This question responds to a gap in existing engineering ethics literature that engineering students’ perceptions (especially first-year students) of professional virtues and values are not sufficiently addressed. We argue that designing effective and engaged ethics education experiences needs to consider the professional values perceived by students and how these values are related to the values communicated in the engineering curriculum. This paper is part of a larger project that compares how engineering students develop moral reasoning and intuition longitudinally across three cultures/countries: the United States, Netherlands, and China. We hope that findings from this paper can be useful for engineering educators to reflect on and design subsequent ethics education programs that are more responsive to students’ perceptions of professional values when beginning an engineering program. 

This paper describes some first-year results of a five-year project funded by the NSF’s ER2 program. The project explores how culture and education affect the ethical reasoning and moral intuitions of engineering students. This paper describes the project and is divided in two parts. First, it begins by describing some background about this project. Second, the paper presents some first-year results. 

If hydrogen evolution photocatalysis are to be deployed at industrial scale, the synthesis of these photocatalytic materials must be both economically and environmentally scalable. This suggests that we must move towards green synthesis of earth-abundant photocatalysts while also maintaining high catalytic performance. Herein, we present the enzymatically driven, aqueous phase, low temperature, synthesis of an earth-abundant nickel sulfide (Ni x S y ) hydrogen evolution cocatalyst, and its integration into a CdS/Ni x S y heterostructured photocatalyst. This resulting photocatalyst provides hydrogen evolution rates (10 500 μmol h −1 g −1 ) comparable to photocatalysts prepared by more traditional routes. Furthermore, the Ni x S y is demonstrated to provide similar activity enhancement to the more traditional, but also more expensive platinum cocatalysts. To achieve this result, we carefully studied and engineered the synthesis environment to maintain enzyme activity towards HS − production while sustaining a sufficient concentration of free Ni 2+ in solution to enable reaction and formation of Ni x S y . Ultimately, this work provides a methodology to control the coordination of metal precursors in low temperature, aqueous systems to allow for precipitation of catalytically active materials and demonstrates the viability of green synthesis pathways for photocatalysts.
