  1. Beginning the path to a bachelor’s degree in community college has the potential to be a more cost-effective higher education option. Previous research on transfer students has focused broadly on curriculum alignment, articulation policies, and academic advising in efforts to reduce credit loss. Credit loss can significantly impact transfer students and result in unnecessary time and costs for them. Minimal research quantifies and visualizes credit loss or explains in detail how and why it occurs throughout students’ entire education trajectories. This study visualizes credit loss for bachelor’s programs seeking engineering transfer students who began at in-state community colleges using data from the sending and receiving institutions. Findings revealed that credit loss can occur throughout the entire degree pathway, including high school dual enrollment and advanced placement credits to community college credits. This work has implications for informing degree pathways and policies that promote successful transfer and degree completion.

  2. This paper examined the role of climate (e.g., interactions with others) in the skill development of engineering and physical science doctoral students. Skill development in graduate school often is connected to students’ primary funding mechanism, which enables students to interact with a research group or teaching team. Advisors also play a pivotal role in the engineering doctoral student experience; however, less is known about how positive mentoring influences specific skill development for engineering doctoral students. Analyzing data from the Graduate Student Funding Survey (n = 615), we focused analyses on three climate Factors (Advising climate; Faculty and staff climate; Peer climate) and specific skill development variables (research, teamwork and project management, peer training and mentoring, and communication). We found that advising climate was statistically significant for all four career-related skills, faculty and staff climate for peer training and mentoring skills only, and peer climate for both peer training and mentoring and communication skills. Our findings highlight the importance of climate from a variety of sources within engineering doctoral programs for the development of career-related skills.

  3. Graduate education in engineering is an extremely challenging, complex entity that is difficult to change. The purpose of this exploratory research paper was to investigate the applicability of the Collective Impact framework, which has been used within community organizing contexts, to organize the change efforts of a center focused on advancing equitable graduate education within engineering. We sought to understand how the conditions of Collective Impact (i.e., common agenda, backbone organization, mutually reinforcing activities, shared measurement system, and continuous communication) could facilitate the organization of equity-focused change efforts across a college of engineering at a single institution. To achieve this, we took an action research approach. We found the Collective Impact framework to be a useful tool for organizing cross-sectional partnerships to facilitate equity-focused change in graduate education; we also found the five conditions of Collective Impact to be applicable to the higher education context, with some intentional considerations and modifications. Through coordinated efforts, the Collective Impact framework can support the goal of reorienting existing decentralized structures, resource flows, and decision processes to foster bottom-up and top-down change processes to advance equitable support for graduate students.

  4. Abstract Self-report assessments are used frequently in higher education to assess a variety of constructs, including attitudes, opinions, knowledge, and competence. Systems thinking is an example of one competence often measured using self-report assessments where individuals answer several questions about their perceptions of their own skills, habits, or daily decisions. In this study, we define systems thinking as the ability to see the world as a complex interconnected system where different parts can influence each other, and the interrelationships determine system outcomes. An alternative, less-common, assessment approach is to measure skills directly by providing a scenario about an unstructured problem and evaluating respondents’ judgment or analysis of the scenario (scenario-based assessment). This study explored the relationships between engineering students’ performance on self-report assessments and scenario-based assessments of systems thinking, finding that there were no significant relationships between the two assessment techniques. These results suggest that there may be limitations to using self-report assessments as a method to assess systems thinking and other competencies in educational research and evaluation, which could be addressed by incorporating alternative formats for assessing competence. Future work should explore these findings further and support the development of alternative assessment approaches.

  5. Abstract There is an increasing emphasis on assessing student learning outcomes from study abroad experiences, but this assessment often focuses on a limited range of outcomes and assessment methods. We argue for shifting to assessing student learningprocessesin study abroad and present the critical incident technique as one approach to achieve this goal. We demonstrate this approach in interviews with 79 students across a range of global engineering programs, through which we identified 173 incidents which were analyzed to identify common themes. This analysis revealed that students described a wide range of experiences and outcomes from their time abroad. Students’ experiences were messy and complex, making them challenging to understand through typical assessment approaches. Our findings emphasize the importance of using a range of assessment approaches and suggest that exploring students’ learning processes in addition to learning outcomes could provide new insights to inform the design of study abroad programs.

  6. To address complex problems in a globalized workplace, future engineers must understand the ethical implications of their work in the global context. International service learning is a possible approach for future engineers to gain an understanding of ethical implications in a global context. The purpose of this study is to investigate the potential benefits that international service learning may add to engineering ethics education. The quantitative study measured senior engineering students’ understanding of ethics from a national sample of students enrolled in capstone design courses (n=2095) in three types of international service learning experiences: capstone, volunteer/work, or co-curricular. Students who participated in international service learning through capstone and volunteer/work experience scored significantly (p<0.01, p<0.001 respectively) higher to questions that measured their understanding of ethics. Males compared to female engineering students showed the largest difference in their understanding of ethics. The integration of international service learning into engineering education should be more seriously considered to aid in more effectively teaching ethics. Male engineering students, who make up nearly 80% of engineering programs, can benefit the most in their ethics education from international service learning.

  7. Abstract BackgroundDetermining the root causes of persistent underrepresentation of different subpopulations in engineering remains a continued challenge. Because place‐based variation of resource distribution is not random and because school and community contexts influence high school outcomes, considering variation across those contexts should be paramount in broadening participation research. Purpose/HypothesisThis study takes a macroscopic systems view of engineering enrollments to understand variation across one state's public high school rates of engineering matriculation. Design/MethodThis study uses a dataset from the Virginia Longitudinal Data System that includes all students who completed high school from a Virginia public school from 2007 to 2014 (N= 685,429). We explore geographic variation in four‐year undergraduate engineering enrollment as a function of gender, race/ethnicity, and economically disadvantaged status. Additionally, we investigate the relationship between characteristics of the high school and community contexts and undergraduate engineering enrollment across Virginia's high schools using regression analysis. ResultsOur findings illuminate inequality in enrollment in engineering programs at four‐year institutions across high schools by gender, race, and socioeconomic status (and the intersections among those demographics). Different high schools have different engineering enrollment rates among students who attend four‐year postsecondary institutions. We show strong associations between high schools' engineering enrollment rates and four‐year institution enrollment rates as well as moderate associations for high schools' community socioeconomic status. ConclusionsStrong systemic forces need to be overcome to broaden participation in engineering. We demonstrate the insights that state longitudinal data systems can illuminate in engineering education research.
