<p>Empathy is increasingly recognized as a critical skill and disposition for engineering practice. Empathy enhances the ability to understand and connect with the thoughts and feelings of others, which helps engineers design concepts and products that are both innovative and aligned to actual user needs and desires. With increased competition and need to innovate in this global economy, there is a growing need for more empathic engineers and an increasing need for more research in the area to prepare future empathic engineers. Previous research indicates community-engagement as a pedagogical approach that provides a context for empathic development. Understanding how empathy changes through a community-engaged design experience can inform the development of a wide range of design and community-engagement experiences. Therefore, this dissertation sought a deeper understanding of the impact of community-engaged design learning on empathic growth and the factors that contribute to that growth for engineering undergraduate students. The study employed a sequential explanatory mixed methods design focused on the empathic development of students enrolled in a community-engaged design course. In the first phase, empathic development was assessed using pre- and post-data collection of empathy and community partner interaction surveys. In the second qualitative phase, semi-structured interviews were conducted with students to build on the results from the quantitative phase and provide insights into the empathic development and import of community relationships identified therein. This study defined empathy as a tripartite phenomenon comprised of the (1) affective dimension emphasizing feelings of concern for another, (2) cognitive dimension emphasizing knowing what another is feeling, and (3) behavioral dimension emphasizing the act of responding based on the cognitive and affective experience. The results highlighted students engaging in how they empathized by showing concern/sympathy—affective dimension—and took the perspective of users –cognitive dimension—in order to understand and make informed design decisions for their projects –behavioral dimension. The quantitative phase did not find any statistically significant practical changes for the overall population. However, based on interviews of students who increased in all three constructs—empathic concern, perspective taking, and interpersonal self-efficacy, which served as proxies for the affective, cognitive, and behavioral dimensions of empathy, empathy manifested and developed due to different factors. These factors included impactful experiences, leadership positions, long-term participation and diverse team members. The results also highlighted prior experiences and overestimating as factors that students attributed for their high pre-test scores in interpersonal self-efficacy.  </p>

Undergraduate research experiences (UREs) are presented as a mechanism for improving the persistence of Black engineering students. However, because most engineering UREs are led by faculty and staff in Colleges of Engineering, it is reasonable to assume they are not immune to the systemic racial issues that plague engineering education. Existing scholarship on epistemic exclusion theorizes that individual biases and institutional practices contribute to faculty of color's scholarship being devalued and deemed illegitimate, but this topic is underexplored in UREs. LSAMP is an NSF-funded program that provides funding for institutions to create UREs for racially minoritized students in STEM, providing a ripe context for exploring the phenomenon of epistemic exclusion in UREs. This explanatory mixed methods study examines facets of epistemic exclusion prevalent in the undergraduate research experiences of Black engineering LSAMP scholars and the practices undergirding it. The findings of this study are based on survey and interview data collected from current and former LSAMP scholars. The survey results reveal perceptions of low levels of epistemic exclusion via scholarly devaluation; and there were no significant differences in survey responses based on race, gender, or whether in an engineering discipline or not. However, the qualitative phase helped explain the quantitative results. Black engineering students, specifically, experienced epistemic exclusion in ways that differ from literature on underrepresented faculty; and they perceived UREs as an opportunity for learning knowledge – not producing it. While positive peer interactions and a welcoming lab enabled epistemic inclusion, a toxic lab culture and inadequate URE program structures enabled epistemic exclusion. These findings have implications for faculty mentors, URE program administrators, policymakers, and education researchers. They are valuable for advancing our understanding of Black engineering students participating in UREs, contributing to national efforts to broaden participation of racially minoritized students in engineering education, and diversifying the research enterprise and the engineering workforce. / Doctor of Philosophy / Undergraduate research experiences (UREs) are presented as a means of improving Black engineering students' persistence.

Complex socioenvironmental problems such as food, energy and water shortages, health impacts from environmental contamination and global climate change present significant challenges to the global community. Addressing these problems will require an interdisciplinary systems-thinking approach that coordinates problem-solving between practitioners of varied disciplines including engineers, physical scientists, economists and other social scientists. Civil and environmental engineers have distinct technical skills necessary to help address these challenges as part of coordinated multidisciplinary efforts towards the achievement of comprehensive and sustainable resolutions to these problems. Ensuring civil and environmental engineers are trained to think and work in this multidisciplinary exchange requires incorporation of systems-thinking into engineering academic curricula. Attempts have been made to incorporate these skill sets into civil and environmental engineering (CEE) coursework. These efforts, as well as evaluation of their effectiveness in training CEE students to think systemically, have lacked in coordination to integrate them as part of the overarching academic curricula. This research advances the current body of knowledge regarding incorporation of systems-thinking into CEE coursework by examining the impacts of system dynamics model based educational tools on systems-thinking learning outcomes of CEE students in a one-semester CEE elective course. The findings suggest that system dynamics modeling can be an effective tool in educating future systems thinkers in the CEE disciplines. / Doctor of Philosophy / Complex socioenvironmental problems such as food, energy and water shortages, health impacts from environmental contamination and global climate change present significant challenges to the global community.

This project documents my efforts to publish STS- and gender theory-informed articles in engineering education journals. It analyzes the processes of writing and revising three articles submitted to three different journals, aiming to shed light on the field of engineering education, gender research therein, and contribute to feminist science studies literature on the challenges and opportunities of interdisciplinary work across women's studies and STEM fields. Building upon Wenger's concept of brokering, I analyze how I brought previously underexplored STS and feminist theory literature into engineering education journals. In producing this dissertation, I aim to illuminate some of the efforts and challenges of bringing STS and Women's Studies (WS) topics into engineering education journals – thus producing an account of brokering practices and an example of scalable scholarship. The first chapter introduces engineering education research (EER) as a field of inquiry, situates my project with respect to current feminist science studies, summarizes the framework of brokering that informs my analyses, and describes my methodology. The second chapter describes my initial attempts at brokering by identifying and bridging differences and the preliminary brokering practices that emerged through writing and revising the first of my three articles. It discusses an article published in Journal of Engineering Education that analyzes the uses of feminist theory in EER and argues that further engagement with a broader range of feminist theories could benefit EER. The third chapter describes how some of these practices were reinforced, but also supplemented, while writing and revising the second article. It discusses an article published in International Journal of Engineering Education that analyzes problematizations of underrepresentation in EER and argues that further reflection upon and formal discussion of how underrepresentation is framed could benefit EER. The forth chapter describes how the established brokering practices guided writing the third article, making the process easier as I had become more comfortable with the requirements and challenges of brokering. It discusses an article submitted to European Journal of Engineering Education that analyzes feminist research methodologies in the context of EER, using data from interviews with feminist engineering educators. The fifth chapter concludes by summarizing the brokering practices and discussing their respective challenges, discussing the implications of this project for STS and WS, and, finally, by discussing other implications for peer review engineering education. The Appendix contains aims, scope, author guidelines, and review criteria for the three journals. Chapters 2, 3, and 4 each begin with a narrative recounting of the practices of brokering that went into producing and revising each article. The narratives describe processes of writing and preparing to submit the articles, reviews received, and subsequent revision processes. The published or submitted articles appear after the brokering narrative. / Ph. D.

The purpose of this study is to understand how engineering students perceive the patterns of culture at the disciplinary level using Hofstede's constructs (power distance, individualism, uncertainty avoidance, and masculinity). The methodology design for this study is mixed methods. More specifically, the design of this study is an explanatory sequential design that begins with the collection and analysis of quantitative data from a version of Hofstede's survey developed by Sharma (2010), followed by subsequent collection and analysis of qualitative data, with the qualitative analysis being informed by preliminary results from the initial quantitative phase. Results from the quantitative study led to a review of the literature regarding Hofstede's main critiques and how other authors have successfully implemented his model in different contexts, and qualitative data collection with semi-structured interviews with undergraduate students. There are three aims of this study, which are addressed and presented in three separate manuscripts. The first aim (Manuscript 1) was identifying if Hofstede's theory of dimensions of national culture can map to academic disciplines. Results from surveying 3388 undergraduate students provided scores on Hofstede's dimensions for each major. Responses matched the national culture of the students rather than the disciplinary culture; therefore, Hofstede's theory didn't map to explain cultural differences in academic majors. The second aim (Manuscript 2) of this study was to review the extensive available literature regarding the critiques of Hofstede's model and its implementation in different settings. Results provided with conceptual, and methodological critiques and misuse of his theory that allowed us to understand the value of his model to understand cultural differences at the national level, as well as the value of the dimensions to inform our qualitative research design. The third aim (Manuscript 3) of this study was to explore students' perceptions of disciplinary engineering culture and how it compared to other disciplines using a qualitative interview protocol that provided rich findings that complement the quantitative results. Results from interviewing 24 students in industrial and systems engineering, electrical and computer engineering, marketing, and industrial design provided with valuable information on how students perceive their disciplinary culture in terms of what it is valued, how they learn, how it is taught, why they learn, how it is going to be used in the workplace, and the reason for select the major. Implications for research and practice in the engineering education field are provided to inform how to make decisions on engineering curriculum, and engineering classrooms and try to find ways to improve some of the issues that engineering education has been facing for the last decades. / Ph.

Science, Technology, Engineering, and Mathematics (STEM) education is spurred by an economic and social need for cross-discipline understanding of complex, worldwide problems, made through intentional connections between two or more STEM subject areas. In order for educators to articulate these connections, research suggests they must have a firm understanding of the individual disciplines through both content and pedagogical approaches. In 2007, as a leader in non-formal STEM education, 4-H made a specific commitment to improve STEM literacy in America's youth by forming the 4-H Science mission mandate, therefore increasing its STEM programming. This qualitative study examined how 4-H educators come to understand STEM and engineering concepts and utilizations, and whether their backgrounds influence their verbalization or expectations of engineering. Narrative themes emerged that help determine how engineering is currently and can continue to be more clearly and consistently articulated and connected within 4-H programming. Themes included 1) a lack of direct connection or understanding of engineering characteristics to 4-H programs, 2) familiarity with and ability to apply engineering characteristics to the Do Reflect Apply model, and 3) the importance of volunteers as STEM and engineering educators within 4-H programming. Strategies for professional development emphasizing engineering understandings, learning outcomes, and broad applications were discovered. Professional development should consider the effects of engineering and STEM self-efficacy, as well as professional identity development. Additionally, it utilize approaches such as the Do Reflect Apply model, and reflect on the learning objectives 4-H educators strive to achieve during STEM programming in conjunction with life-skills. / Master of Science in Life Sciences / In 2007, 4-H made a specific commitment to improve Science, Technology, Engineering, and Mathematics (STEM) literacy in America’s youth by forming the 4-H Science mission mandate. However, research suggests in order for educators to successfully implement STEM programming, they need to understand the content and best teaching practices, which presents a unique obstacle for 4-H educators as many lack formal education in both. By conducting interviews with current 4-H educators in Virginia, this research begins to highlight the importance behind STEM understanding and STEM teaching practices – particularly as they pertain to engineering projects. These interview and data analysis process uncovered common themes including connections between engineering and current 4-H educational approaches, as well as the existing barriers between volunteers as STEM educators and successful programming. In order to improve STEM education within 4-H, professional development strategies focusing on engineering characteristics, outcomes aligning with 4-H goals, and applications to real-world problems should be implemented.

The General Engineering Program exists at Virginia Tech to provide curriculums that engage, challenge and support entry-level engineers. One important part of this initiative is helping students identify with a specific engineering branch, and overtime develop an identity within it. Yet, there exists little research on what entry-level engineers believe it means to be an engineer, especially during these stages of early formation and continual shifting. In order to generate insight on this topic we developed a contextual inquiry method to help inquire into engineering identity. Two participants were placed in an online chatroom and allowed to talk for ten minutes, with one trying to answer the question 'Am I talking to an engineer or not?' and asked to give their reasoning. Comparisons allow entry-level engineering students to articulate their beliefs on what characteristics, behaviors and personalities make up their cohort -- thus exposing their ideas about identity. Moreover, this methodology also provides opportunities for participants to critique their own bias and further develop and expose their opinions on identity. Additionally, our findings showcase the complexity around student's perceptions of engineers. For example, participants' responses pointed to: many sources that inform identity, the difficulty of identifying what is uniquely engineering, how identity is impacted by the ideal image of an engineer, that identity is a spectrum, and that identity varies with respect to associations and time. As a result, through our inquiry and representation of results we demonstrate the validity of our methodology as a HCI research tool along with the power of narrative forms of representation. / Master of Science / The General Engineering Program exists at Virginia Tech to provide curriculums that engage, challenge and support entry-level engineers.

The value of diversity in the Science, Technology, Engineering, and Math (STEM) fields has long been a leading topic of discussion among campus administrators and government officials. However, the number of African American women in STEM, and the engineering field in particular, has seen little growth over the past twenty years. To change this trend, there must be enhanced efforts to provide an environment and resources to support the retention of these women, and mentoring can play a key role. To gain a better understanding of the mentoring needs of these women, this research investigates the mentoring experiences of 16 current senior African American female engineering students. What is clear is that African American women have a unique set of experiences based on the multiple sets of identity groups that they claim membership in. Intersectionality emphasizes the implications of the multiplication of these identities and how that multiplication impacts experiences. This research, addresses the intersection by exploring faculty mentoring relationships, with particular focus on the implications of having a matched (same race and gender) or an unmatched mentor. Current research is inconsistent on the benefits of each type. Using phenomenography, this investigation of the various aspects of mentoring relationships that are salient to 16 African American women in engineering uncovered seven categories of mentoring: Guide, Proactive Supporter, Reactive Listener, Nurturer, Just in Time, Caring, and Role Model. Variation across these mentoring categories were reflected in the mentoring aspects that participants perceived. This set of interpersonal (listen, invested, and shared experience) and professional (development, opportunity, advice, and example) aspects depicted a set of mentoring types that varied in comprehensiveness. Additionally, variation in the race and gender of each mentor across each category suggested some trends surrounding the mentor characteristics that most frequently provided certain aspects. However, all of the categories that emerged were perceived to be effective. It is desired that the results of this research will impact the ways in which faculty understand the needs of African American women in engineering. / Ph. D.
