We contend a better way to teach ethics to freshman engineering students would be to address engineering ethics not solely in the abstract of philosophy or moral development, but as situated in the everyday decisions of engineers. Since everyday decisions are not typically a part of university courses, our approach in large lecture classes is to simulate engineering decision-making situations using the role-playing mechanic and narrative structure of a fictional choose-your-own-adventure. Drawing on the contemporary learning theory of situated learning [1], [2], such playful learning may enable instructors to create assignments that induce students to break free of the typical student mindset of finding the “right” answer. Mars: An Ethical Expedition! is an interactive, 12 week, narrative game about the colonization of Mars by various engineering specialists. Students take on the role of a head engineer and are presented with situations that require high-stakes decision-making. Various game mechanics induce students to act as they would on-the-fly, within a real engineering project context, using personal reasoning and richly context-dependent justifications, rather than simply right/wrong answers. Each segment of the game is presented in audio and text that ends with a binary decision that determines what will happen next in the story. Historically, this game had been led by an instructor and played weekly, as a whole-class assignment, completed at the beginning of class. The class votes and the majority option is presented next. In addition to the central decision, there are also follow-up questions at the end of each week that provoke deeper analysis of the situation and reflection on the ethical principles involved. This prototype was initially developed within a learning management system, then supported by the TwineTM game engine, and studied in use in our 2021 NSF EETHICS grant. In 2022-23 the game was redesigned and extended using the GodotTM game engine. In addition to streamlining the gameplay loop and reducing the set-up and data management required by instructors, this redesign supported instructors with an option to allow the game to be student-paced and played by individual students or to keep the instructor-led 12 week whole-class playstyle. Our proposed driving research question is "In what ways does individual student play differ from whole class instructor-led play with regard to learning that ethical behavior is situated?" In the next phase of our ongoing investigation, we plan to further evaluate the use of playful assessment to estimate its validity and reliability in comparison to current best practices of engineering ethics assessment. 

Ethics education has been recognized as increasingly important to engineering over the past two decades, although disagreement exists concerning how ethics can and should be taught in the classroom. With the support from the National Science Foundation (NSF) Improving Undergraduate STEM Education (IUSE) program, a collaboration of investigators from the University of Connecticut, New Jersey Institute of Technology, University of Pittsburgh, and Rowan University are conducting a mixed-methods project investigating how game-based or playful learning with strongly situated components can influence first-year engineering students’ ethical knowledge, awareness, and decision making. We have conducted preliminary analyses of first-year students’ ethical reasoning and knowledge using the Defining Issues Test 2 (DIT-2), Engineering Ethics Reasoning Instrument (EERI), and concept map assessment to characterize where students “are at” when they come to college, the results of which can be found in past ASEE publications. Additionally, we have developed a suite of ethics-driven classroom games that have been implemented and evaluated across three universities, engaging over 400 first-year engineering students. Now in its third year, we are modifying and (re)designing two of the game- based ethics interventions to (1) more accurately align with the ethical dilemmas in the EERI, (2) allow for more flexibility in modality of how the games are distributed to faculty and students, and (3) provide more variety in terms of the contexts of ethical dilemmas as well as types of dilemmas. As part of the continued development of the game-based ethical interventions, we are piloting a new assessment tool specific for playful learning in engineering ethics and aimed at measuring students ethical reasoning and thought process after they have played the game(s). The past year has provided insight into the potential limitations of the existing methods for measuring changes in ethical reasoning in students, as well as compared changes between first year and senior students. The last year has highlighted the situated or contextual nature of much of the ethical decision making that students do and incorporated both qualitative and quantitative methods. Further results from this investigation will provide the engineering education community with a set of impactful and research-based playful learning pedagogy and assessment that will help students confront social and ethical dilemmas in their professional lives. 

This Work-in-Progress paper stems from an NSF-sponsored project in which a series of game- based activities have been developed for the purpose of enhancing instruction in engineering ethics. These activities have been integrated into first year engineering courses on several campuses. One of these activities is called Toxic Workplaces. In gameplay, the students are presented with scenarios that involve ethical dilemmas. Each scenario comes with several possible responses. The game involves the student/player attempting to rank these possible responses in order of popularity. Thus, players do not necessarily need to take a position on what they themselves would do, but rather are attempting to match the results of survey data that was collected previously. In the Fall of 2022, a team of eight undergraduate students completed a project in which they developed new scenarios, greatly expanding the range of options available to an instructor who wishes to incorporate Toxic Workplaces into a course. This paper describes the game itself and its motivation, and discusses the process by which the undergraduate student team generated and refined their new scenarios. 

Ethics education has been recognized as increasingly important to engineering over the past two decades, although disagreement exists concerning how ethics can and should be taught in the classroom. With active learning strategies becoming a preferred method of instruction, a collaboration of authors from four universities (University of Pittsburgh, University of Connecticut, Rowan University and New Jersey Institute of Technology) are investigating how game-based or playful learning with strongly situated components can influence first-year engineering students’ ethical knowledge, awareness, and decision making. This paper offers an overview and results of the progress to date of this three year, NSF Improving Undergraduate STEM Education (IUSE) grant that aims to (1) characterize the ethical awareness and decision making of first-year engineering students, (2) develop game-based learning interventions focused on ethical decision making, and (3) determine how (and why) game-based approaches affect students’ ethical awareness in engineering and the advantages of such approaches over non game-based approaches. Now in its second year, the authors have conducted a preliminary analysis of first-year students' ethical knowledge and organization via a concept mapping approach and have measured students' ethical reasoning using the Defining Issues Test 2 (DIT2) and Engineering Ethics Reasoning Instrument (EERI). Further, the authors have developed a suite of ethics-driven games that have been implemented across three of the universities, engaging over 400 first-year engineering students. Evaluation data has also been gathered for further game development and to assess initial student engagement and learning. Year 1 has provided insight into where first-year engineering students “are at” in terms of ethical knowledge and reasoning when they come to college, and how game-based instruction can be effective in the development of these students into moral agents who understand the consequences of their decisions. Further results from this investigation will provide the engineering education community with a set of impactful and research-based playful learning pedagogy and assessment that will help students confront social and ethical dilemmas in their professional lives. 

Every year new safety features and regulations are employed within the process industry to reduce risks associated with operations. Despite these advancements chemical plants remain hazardous places, and the role of the engineer will always involve risk mitigation through real time decision making. Results from a previous study by Kongsvik et al., 2015 indicated that there were three types of decisions in major chemical plants: strategic decisions, operational decisions, and instantaneous decisions. The study showed the importance for improving upon engineers’ operational and instantaneous choices when tasked with quick solutions in the workforce. In this research study, we dive deeper to understand how senior chemical engineering students’ prioritize components of decision making such as budget, productivity, relationships, safety, and time, and how this prioritization may change as a result of participation in a digital immersive training environment called Contents Under Pressure. More specifically, we seek to address the following two research questions: (1) How do senior chemical engineering students prioritize safety in comparison to criteria such as budget, personal relationships, plant productivity, and time in a process safety context, and (2) How does senior chemical engineering students’ prioritization of decision making criteria (budget, personal relationships, plant productivity, safety, and time) change after exposure to a virtual process safety decision making environment? As part of this study, 187 senior chemical engineering students from three separate institutions completed a pre- and post-reflection survey around their engagement with Contents Under Pressure and asked them to rank their prioritizations of budget, productivity, relationships, safety, and time. Data was analyzed using descriptive statistics, and Friedman and Wilcoxon-sign-rank post hoc analyses were completed to determine any statistical differences between the rankings of decision making factors before and after engagement with Contents Under Pressure. Simulating process safety decision making with interactive educational supports may increase students’ understanding of genuine workplace environments and factors that contribute to process safety, without the real world hazards that result from poor decision making. By understanding how students prioritize these factors, chemical engineering curricula can be adapted to focus on the areas of process safety decision making where students need the largest improvement, thereby better preparing them to enter the engineering workforce.
