Background Nonbinary engineering students (i.e., engineering students that identify as outside of the gender binary) must navigate a cis- and heteronormative society, in addition to a male dominated engineering culture. Nonbinary students in higher education report high levels of minority threat, lower levels of persistence than cisgender peers and lessened feelings of belonging. One avenue for supporting nonbinary students’ persistence in engineering is to increase understanding of the types of individuals that support nonbinary students and the supports available to nonbinary engineering students. For this study, we are utilizing social capital theory and Devor’s witnessing and mirroring framework to explore the supports nonbinary engineering students access through their social networks and how those supports impact persistence. Social capital, the resources embedded into social relationships, has been used as both an indicator and outcome in relation to students’ well-being, belonging, academic success, and persistence. Devor’s witnessing and mirroring framework brings greater meaning to the value of transgender and cisgender alters in a nonbinary engineers’ network. Specifically, how cisgender alters witness a nonbinary person’s identity as an outsider to gender nonconformity and how transgender alters mirror a nonbinary person’s experience as an insider to gender nonconformity. Purpose: The purpose of this work in progress is to identify supports that are impactful on nonbinary engineering students’ persistence in their majors and careers. Specifically, we ask the questions: 1) What supports do alters, of differing genders, provide that witness and mirror nonbinary engineers; 2) to what extent are supports provided by alters impactful on students' success in their majors and careers? Methodology/approach: We purposely selected 4 nonbinary engineering students to interview from a larger study on engineering students’ social capital and professional skills. Nonbinary engineering students were asked about their experiences of being nonbinary in engineering spaces, the support they received from cisgender and transgender alters and the impact of that support on their persistence in engineering. We analyzed the themes in the interviews by coding the alters mentioned, the types of supports provided (mirroring, witnessing, expressive and instrumental) and the impact of supports on persistence. Future Work and Implications: The finding of this study will contribute to a greater understanding of the social capital and social networks of nonbinary students, as there is dearth of research on their experiences in engineering spaces. This work can guide our understanding of the supports that nonbinary engineering students have available to them and perhaps more importantly, the supports they do not have available to them. The findings from this study will be used to inform organizational and institutional policies to support engineering students in accessing more social capital.

It is well established that access to social supports is essential for engineering students’ persistence and yet access to supports varies across groups. Understanding the differential supports inherent in students’ social networks and then working to provide additional needed supports can help the field of engineering education become more inclusive of all students. Our work contributes to this effort by examing the reliability and fairness of a social capital instrument, the Undergraduate Supports Survey (USS). We examined the extent to which two scales were reliable across ability levels (level of social capital), gender groups and year-in-school. We conducted two item response theory (IRT) models using a graded response model and performed differential item functioning (DIF) tests to detect item differences in gender and year-in-school. Our results indicate that most items have acceptable to good item discrimination and difficulty. DIF analysis shows that multiple items report DIF across gender groups in the Expressive Support scale in favor of women and nonbinary engineering students. DIF analysis shows that year-in-school has little to no effect on items, with only one DIF item. Therefore, engineering educators can use the USS confidently to examine expressive and instrumental social capital in undergraduates across year-in-school. Our work can be used by the engineering education research community to identify and address differences in students’ access to support. We recommend that the engineering education community works to be explicit in their expressive and instrumental support. Future work will explore the measurement invariance in Expressive Support items across gender. 

Research has shown that creating an online learning community is vital in Model-Based Systems Engineering (MBSE) training programs and can be facilitated via the Community of Inquiry (CoI) framework. For professional learners, an online learning community is influenced by their organizational affiliations. The purpose of this research is to explore learning experiences in groups of professional learners with different and homogenous organizational affiliations in an asynchronous online MBSE module. Through the case study methodology, this research examines four sources of data from two cases: Case 1—learners from different organizations (n = 7); and Case 2—overwhelming majority of learners from the same organization (n = 19). Results showed that learners from the same organization reported higher social presence, which, in turn, corresponded to a higher cognitive presence and higher motivation for future MBSE learning. Based on our findings, we recommend that organizations seeking MBSE adoption coordinate with online course providers to create cohorts to participate in the same offerings to facilitate the process of learning community building. We also recommend MBSE course providers facilitate social interaction on multiple communication platforms and create orientation activities for learners from different organizations to promote social presence. 

This full research paper presents the exploratory factor analysis (EFA) results for the Professional Skill Opportunities survey (PSO) we designed to measure undergraduate engineering students’ opportunities to develop and practice important nontechnical professional skills. We use Dall’alba’s “ways of being” as the theoretical framework for the survey development and generated construct definitions based on past literature, expert review, and cognitive think-aloud interviews. We administered the survey in an engineering class at the beginning of the Spring 2022 semester. After comparing the three EFA models based on goodness-of-fit indices and model interpretability aligned to the theoretical model, the researchers selected a five-factor model. The EFA result and literature on leadership and teamwork showed these two skills are highly interrelated and could be combined into one construct to stress the “sharedness” of leadership responsibilities in teams. The result allowed our team to refine our item pool, revise construct definitions, and generate new items. In future work, we will administer the revised PSO survey to the same population at the end of the same semester as further validation. We also plan to explore the relationship between professional skill development opportunities and students’ social support. We hope the PSO survey can provide educators and institutions a means to offer scaffoldings and more opportunities for professional skill development and better prepare students for the engineering workforce. 

This Research Work-In-Progress reports the implementation of an Object Assembly Test for sketching skills in an undergraduate mechanical engineering graphics course. Sketching is essential for generating and refining ideas, and for communication among team members. Design thinking is supported through sketching as a means of translating between internal and external representations, and creating shared representations of collaborative thinking. While many spatial tests exist in engineering education, these tests have not directly used sketching or tested sketching skill. The Object Assembly Test is used to evaluate sketching skills on 3-dimensional mental imagery and mental rotation tasks in 1- and 2-point perspective. We describe revisions to the Object Assembly Test skills and grading rubric since its pilot test, and implement the test in an undergraduate mechanical engineering course for further validation. We summarize inter-rater reliability for each sketching exercise and for each grading metric for a sample of sketches, with discussion of score use and interpretation.
