1. Examining the Characteristics and Traits of Young Engineers’ Moral Exemplars

   Carter, Darius G; Claussen, Stephanie (June 2024, ASEE PEER)

   Engineering education commonly deemphasizes the moral and ethical teaching required for future engineers. Measuring the ethical values that engineering students and professionals possess, and how those views change over time, is a challenging prospect given the complexity of such concepts. One proposed method to characterize a person’s moral development is by asking them to identify a moral exemplar. In this paper, we explore who engineering students and early-career engineering professionals identify as moral exemplars and the traits and characteristics they use to describe these moral exemplars. The data used in this paper comes from a series of two longitudinal, mixed-methods projects which explored engineering students’ and professionals’ perceptions of ethics and social responsibility. During these projects, three interviews were conducted with longitudinal participants: one at the start of the first year of their engineering undergraduate studies (T1, n = 112), a second during their senior year (T2, n = 33), and a third 2-3 years after they graduated and started their engineering careers (T3, n = 20). This study focuses on interviewees' responses to one question: “Can you identify and describe someone, (for example, someone you know, a historical figure, or a famous person), that you think exemplifies moral character or professional or personal integrity?” In this paper, we identify and categorize the identities of these chosen moral exemplars. The list of categories was made and modified according to the trends we saw in moral exemplars of the engineering students. Occasionally, we had trouble determining how to categorize a response and, as a result, would put the moral exemplar into two categories. Additionally, we analyze the traits interviewees use to describe their moral exemplars, with the Big 5 Personality Traits used as an analytical framework [2]. When studying the personality traits of the moral exemplars, we would rank them from 1-10 depending on if they either positively (10) or negatively (1) align with the traits [2]. If the trait was not described, we would rank them a 0. From our analysis, a few notable patterns emerged. In T1, the largest category was family members accounting for 38% of the moral exemplars. In T2, family members were again the largest category, but now made up 22% of the moral exemplars. Additionally, around 60% of both the T1 and T2 participants cited their moral exemplars as someone they know personally. Interestingly the gender of the Moral exemplars for T1 and T2 is 68% male, 14% female and 18% other/not specified. We plan to compare the gender of the interviewees with the moral exemplars they identified to understand if there was any correlation between the two factors. We are also investigating longitudinal changes over time in the categories of the moral exemplars identified by participants. Finally, we are also comparing the personality traits of the moral exemplars described by our young engineer participants to prior work investigating the personalities of moral exemplars.

2. A systematic literature review of student evaluation of peer exemplars and implications for design, Technology, and Engineering Learning

   Thorne, Scott; Mentzer, Nathan; Bartholomew, Scott; Strimel, Greg J (September 2024, International Journal of Technology and Design Education)

   In design courses, reviewing how others have solved design problems or completed projects is common practice and often encouraged by educators. Using student work as examples can provide context for assessment criteria and help students approach new design problems. While studies have explored the use of exemplars in various disciplines, little research has focused on which exemplars to use (e.g., high-quality, low-quality) in design, technology, and engineering fields. To address this gap, researchers conducted a literature review of 33 articles on exemplar use in secondary and post-secondary education. The analysis revealed nine themes related to exemplar use and their impact on student learning, including (1) Clarity of instruction, (2) Learner focus, (3) Motivation for learning, (4) Student reflection on learning, (5) Building student self-efficacy, (6) Identifying instructional challenges, (7) Providing contrasting cases, (8) The relationship between exemplar quality and student work quality, and (9) Raising the bar for learning outcomes. Findings suggest that simply providing an exemplar is not enough and that the selection of an exemplar can have positive or negative impacts on student motivation, understanding, and application. Carefully selecting exemplars and engaging in dialogue with students can help them identify expectations, recognize quality work, and identify potential misconceptions. These findings have implications for those involved in design, technology, and engineering education. Educators can use these findings to guide their selection of exemplars and engage students in meaningful dialogue to aid their learning. Researchers can also use these findings to further investigate the use of exemplars in these fields.

3. What does a radical exemplar view not predict? A commentary on Ambridge (2020)

   This article reviews two aspects of human learning: (1) people draw inferences that appear to rely on hierarchical conceptual representations; (2) some categories are much easier to learn than others given the same number of exemplars, and some categories remain difficult despite extensive training. Both of these results are difficult to reconcile with a learning and categorization system that operates only on specific exemplars. More generally, the article argues that specifying the empirical phenomena that a radical exemplar does not predict would aid in clarifying the radical exemplar proposal.

4. Evaluating Engineering Students’ Moral Sensitivity in a Natural Disaster Context

   Lapatin, M.; Barrens, S.; & Kim, K.; Padgett Walsh, K.; Feinstein, S.; Rutherford, C.; Nguyen, L.; Faust, K. (August 2022, ASEE PEER)

   Engineered systems are designed to serve societal needs, from bridges providing mobility to communication systems enabling the transfer of information. It is essential that engineers recognize the social impact of their work to ensure they provide equitable benefits across communities when implementing such systems. In times of crisis, such as after natural disasters, these ethical considerations and awareness of community needs are especially important. Ethical development must begin when engineers are still students so that they can be trained to consider ethical issues before they begin working. Ethical development can be observed using James Rest’s Four-Component Model of Morality: moral sensitivity, moral judgement, moral motivation, and moral behavior. Previous work has focused largely on the second stage, moral judgement, which describes the ability to determine which action is morally right when confronted with an ethical issue. Here, however, we focus on the first stage, moral sensitivity, emphasizing one’s ability to recognize a moral issue. Studies show that while moral sensitivity does not always lead to moral behavior; moral sensitivity can help explain variances in moral behavior. Researchers argue that pinpointing students’ gaps in moral sensitivity can help educators identify gaps in engineering ethics curriculum. Towards this goal, we interviewed undergraduate engineering students to evaluate their moral sensitivity, using a current event, the 2021 Hurricane Ida in Southern Louisiana, as background. This natural disaster provided a useful context to evaluate moral sensitivity due to the complex effects of such a crisis on engineered, natural, and social systems. The story is framed using Lind’s Indicators of Ethical Sensitivity, providing the story characteristics, stakeholders, and consequences. We asked interviewees to provide the final indicator—ethical issues. Using a qualitative content analysis, we found that interviewees connected several ethical issues with the primary consequence of socioeconomic inequities. Identified ethical issues included topics of climate change, infrastructure, disaster planning, and corporate/government accountability. Implications of this study include recommendations for future moral sensitivity research and applications to improve classroom learning.

5. The role of category- and exemplar-specific experience in ensemble processing of objects

   People can relatively easily report summary properties for ensembles of objects, suggesting that this information can enrich visual experience and increase the efficiency of perceptual processing. Here, we ask whether the ability to judge diversity within object arrays improves with experience. We surmised that ensemble judgments would be more accurate for commonly experienced objects, and perhaps even more for objects of expertise like faces. We also expected improvements in ensemble processing with practice with a novel category, and perhaps even more with repeated experience with specific exemplars. We compared the effect of experience on diversity judgments for arrays of objects, with participants being tested with either a small number of repeated exemplars or with a large number of exemplars from the same object category. To explore the role of more prolonged experience, we tested participants with completely novel objects (random-blobs), with objects familiar at the category level (cars), and with objects with which observers are experts at subordinate-level recognition (faces). For objects that are novel, participants showed evidence of improved ability to distribute attention. In contrast, for object categories with long-term experience, i.e., faces and cars, performance improved during the experiment but not necessarily due to improved ensemble processing. Practice with specific exemplars did not result in better diversity judgments for all object categories. Considered together, these results suggest that ensemble processing improves with experience. However, the role of experience is rapid, does not rely on exemplar-level knowledge and may not benefit from subordinate-level expertise.
