This empirical research full paper describes a project aimed at increasing graduation rates among low-income, academically talented engineering students by implementing first-year student initiatives. The project, supported by an NSF-SSTEM (National Science Foundation Scholarships in Science, Technology, Engineering and Mathematics) grant at a Northeastern US institution, is in its second year of a four-year plan. Grounded in Tinto’s conceptual model of student motivation and persistence, the project emphasizes early interventions, which are critical for low-income students facing external challenges that may impact their decision to stay in college or enter the workforce. We developed and integrated the SSTEM project aiming to increase four key elements, which based on Tinto will also increase persistence. The SSTEM project includes scholarships, an Engineering Learning Community (ELC) that promotes cohort-based learning and living, mentorship, and participation in personal and professional development seminars. Additionally, inclusive practices have been integrated into first-year engineering lab courses to improve curriculum accessibility. This paper evaluates the validity of an instrument designed to assess the project's impact on students’ college experiences and persistence. It builds on prior exploratory factor analysis (EFA) research by presenting confirmatory factor analysis (CFA) findings to further validate the instrument. 

Teaming is a core part of engineering education, especially in the first and last years of engineering when project work is a prevalent focus. The literature on the effects of working in diverse teams is mixed. Negative findings include decreased affect, increased frustration, and sustained conflict in teams. Positive findings include increased productivity, production of high quality products, and divergent-thinking and idea generation. Given these mixed findings, it becomes important to not only understand the practical outputs of working in diverse teams, but also how the experience of working in diverse teams influences whether students see themselves as engineers and whether or not they feel they belong in engineering. Our project, Building Supports for Diversity through Engineering Teams, investigates how students’ attitudes towards diversity influence how students experience work in diverse teams through addressing two main research questions: 1) What changes occur in students’ diversity sensitivity, multicultural effectiveness, and engineering practices as a result of working in diverse teams? 2) How do students’ perceptions of diversity, affect, and engineering practices change because of working on diverse teams? Using a multi-method approach, we deployed survey instruments to determine changes in student’s attitudes about teaming, diversity sensitivity, and openness attitudes. We also observed students working in teams and interviewed these students about their perceptions of diversity and experiences in their teams. Preliminary results of the quantitative phase show that variance in students’ attitudes about diversity significantly increase over the semester, further reflecting the mixed results that have been seen previously in the literature. Additionally, Social Network Analysis was used to characterize the social structure practices of a multi-section, large-enrollment first-year engineering course. This reveals the underlying social structure of the environment, its inclusiveness, and how diverse students work with others on engineering. Initial results indicate that students are included in social networks regardless of gender and race. Preliminary results of the qualitative phase, using Interpretive Phenomenological Analysis, have yielded relationships between student’s definitions, valuation, and enactment of diversity in engineering spaces. Individual student’s incoming attitudes of diversity and previous experiences interact with practical needs in first-year engineering classrooms to create different microclimates within each team. These microclimates depict tensions between what instructors emphasize about diversity, stereotypes of engineering as focused on technical instead of social skills, and pragmatic forces of “getting the job done.” This knowledge can help explain some of the complexity behind the conflicting literature on diversity in teams. Ultimately, this research can help us understand how to build inclusive and diverse environments that guide students to learn how to understand their own complex relationship, understanding, and enactment of diversity in engineering. By understanding how students make sense of diversity in engineering spaces, educators and researchers can figure out how to introduce these concepts in relevant ways so that students can inclusively meet the grand challenges in engineering. This curriculum integration, in turn, can improve team interactions and the climate of engineering for underrepresented groups.
