  1. In recent years, research has associated grade point average (GPA) with a variety of student outcomes during their undergraduate careers. The studies link higher GPAs to students being more likely to graduate in their major, while lower GPAs have been linked to students switching majors or leaving the institution. Further research, which focuses on how Black female and male students remain successful in different engineering degrees, is necessary to identify the underlying elements contributing to their entrance into and exit from engineering disciplines. This quantitative examination of trends among the GPAs of Black women and men is part of a larger NSF-funded mixed-methods study that includes in-depth student interviews of Black students who persisted in and switched from ME. In this quantitative paper, we examine the GPA patterns of Black students in Mechanical Engineering (ME). Students who have ever enrolled in ME have four potential, mutually exclusive, outcomes: 1) they can persist for 12 semesters without graduating; 2) they can graduate in ME within 12 semesters; 3) they can switch to another major; or 4) they can leave school. In this research, we identify the most common GPA patterns associated with graduated ME students. We hypothesize a relationship between distinct GPA patterns and whether a student persists in ME, graduates in ME, switches away from ME, or leaves the institution altogether. This quantitative investigation uses the Multiple-Institution Database for Investigating Engineering Longitudinal Development (MIDFIELD) to collect the cumulative GPA of ME students at each term. We use a functional cluster analysis approach to group similar patterns. First, a function is fit to each student record. Then a cluster analysis is conducted on the function parameters to identify natural groupings in the data. Once students are grouped according to their GPA profile, we examine the other characteristics and outcomes of the group. We present a visual quantitative analysis of the patterns in the GPAs of Black women and men who enroll in ME. Clustering analysis suggests that first-time-in-college (FTIC) Black female students in ME who graduated have a higher proportion of students in the higher GPA clusters than the proportion of FTIC Black male students who graduated in ME. A higher proportion of the male student population is clustered in the lower GPA cluster groups as compared to women in the lower GPA cluster groups. A higher proportion of students who graduated are in the higher GPA clusters than the proportion of graduated students in the lower GPA clusters.

  2. Our transformative mixed-methods project, funded by the Division of Engineering Education and Centers, responds to calls for more cross-institutional qualitative and longitudinal studies of minorities in engineering education. Our project builds on prior work that demonstrated the impacts of gender and race on academic trajectories in Electrical, Computer, and Mechanical Engineering (EE, CpE, and ME, respectively) to answer the following questions: 1. Why do Black men and women choose and persist in, or leave, EE, CpE, and ME? 2. What are the academic trajectories of Black men and women in EE, CpE, and ME? 3. In what ways do these pathways vary by gender or institution? 4. What institutional policies and practices promote greater retention of Black engineering students? In Year 4 of our project, the research team has engaged in deeper analysis of our quantitative data from the Multi-Institution Database for Investigating Engineering Longitudinal Development (MIDFIELD) database and our qualitative data from 79 in-depth interviews of students in the three study majors at our four study institutions. Expanding on findings presented in prior years, in this paper, we describe emergent results from three papers from Year 4 of our project: • Paper # 1: “Who Tells Your Story? Qualitative Methods for Establishing Connections and Eliciting Narratives” was published in the International Journal of Qualitative Methodology in 2021. It includes a description of the development of the card-sorting activity that students completed to describe their reasons for choosing to major in engineering and an exploration of different ways to analyze the data. Analysis of how frequently the factors influencing the major choice were chosen by interviewees has allowed us to identify those factors that carry the greatest importance for students and how they vary for persisters and switchers. • Paper # 2: “GPA Trends of Black Mechanical Engineering Students”: Our early qualitative work has led to questions about students who switch majors and those who leave the university. We are using the MIDFIELD database to better understand characteristics of students who switch majors and who leave the university. We will use functional cluster analysis to group the GPA trends to find clearly defined groups of students' GPA. Preliminary findings suggest that the students who switch majors have different GPA trends than the students who leave their institutions. This holds true for whether the student chooses to switch their major and stay within engineering and students who choose to leave engineering. • Paper # 3: “Pride and Prestige: Factors Influencing How and Why Black Students Choose to Attend a Predominantly White Institution or a Historically Black University”: In this paper, we explore the reasons that students in our study majors decided to attend either a HBCU or a PWI. Our early analysis revealed that students had diverse reasons for college choice, including affordability, location, familiarity with the institution, family encouragement and connections, and prestige of the university. Our paper will also describe the differences between students who attended a HBCU or PWI in their rationale for deciding to attend a particular university.
