1. Design Educators’ Conceptions of Prototyping in Engineering Design Courses

   Ali, Hadi ; Lande, Micah ( June 2019 , ASEE Annual Conference proceedings)

   This is a research study that investigates the range of conceptions of prototyping in engineering design courses through exploring the conceptions and implementations from the instructors’ perspective. Prototyping is certainly an activity central to engineering design. The context of prototyping to support engineering education and practice has a range of implementations in an undergraduate engineering curriculum, from first-year engineering to capstone engineering design experiences. Understanding faculty conceptions’ of the reason, purpose, and place of prototyping can help illustrate how teaching and learning of the engineering design process is realistically implemented across a curriculum and how students are prepared for workmore »practice. We seek to understand, and consequently improve, engineering design teaching and learning, through transformations of practice that are based on engineering education research. In this exploratory study, we interviewed three faculty members who teach engineering design in project-based learning courses across the curriculum of an undergraduate engineering program. This builds on related work done by the authors that previously investigated undergraduate engineering students’ conceptions of prototyping activities and process. With our instructor participants, a similar interview protocol was followed through semi-structured qualitative interviews. Data analysis has been undertaken through an emerging thematic analysis of these interview transcripts. Early findings characterize the focus on teaching the design process; the kind of feedback that the educators provide on students’ prototypes; students’ behavior while working on design projects; and educators’ perspectives on the design course. Understanding faculty conceptions with students’ conceptions of prototyping can shed light on the efficacy of using prototyping as an authentic experience in design teaching and learning. In project-based learning courses, particular issues of authenticity and assessment are under consideration, especially across the curriculum. More specifically, “proportions of problems” inform “problem solving” as one of the key characteristics in design thinking, teaching and learning. More attention to prototyping as part of the study of problem-solving processes can be useful to enhance understanding of the impact of instructional design. Challenges for teaching engineering design exist, and may be due to difficulties in framing design problems, recognizing what expertise students possess, and assessing their expertise to help them reach their goals, all at an appropriate place and ambiguity with student learning goals. Initial findings show that prototyping activities can help students become more reflective on their design. Scaffolded activities in prototyping can support self-regulated learning by students. The range of support and facilities, such as campus makerspaces, may also help students and instructors alike develop industry-ready engineering students.« less

   Workplace engineering problems are different from the problems that undergraduate engineering students typically encounter in most classroom settings. Students are most commonly given well-structured problems which have clear solution paths along with well-defined constraints and goals. This paper reports on research that examines how undergraduate engineering students perceived solving an ill-structured problem. Eighteen undergraduate civil engineering students were asked to solve an ill-structured engineering problem, and were interviewed after they completed solving the problem. This qualitative study is guided by the following research question: What factors do students perceive to influence their solving of an ill-structured civil engineering problem? Students’more »responses to seven follow-up interview questions were transcribed and reviewed by research team members, which were used to develop codes and themes associated with these responses. Students’ transcripts were then coded following the developed codes. The analysis of data revealed that students were generally aware of the main positives and negatives of their proposed solutions to the ill-structured problem and reported that their creativity influenced their solutions and problem solving processes. Student responses also indicated that specific life events such as classes that they had taken, personal experiences, and exposure to other ill-structured problems during an internship helped them develop their proposed solution. Given students’ responses and overall findings, this supports creating learning environments for engineering students where they can support increasing their creativity and be more exposed to complex engineering problems.« less
3. Where’s My Whiteboard? The Challenge of Moving Active-learning Mathematics Classes Online

   Nelson, Jill K. ; Rosenberg, Jessica ; Fernandez, Kathryn ; Shank, Julie ( July 2021 , 2021 ASEE Virtual Annual Conference)

   This research paper studies the challenges that mathematics faculty and graduate teaching assistants (GTAs) faced when moving active and collaborative calculus courses from in-person to virtual instruction. As part of a larger pedagogical change project (described below), the math department at a public Research-1 university began transitioning pre-calculus and calculus courses to an active and collaborative learning (ACL) format in Fall 2019. The change began with the introduction of collaborative worksheets in recitations which were led by GTAs and supported by undergraduate learning assistants (LAs). Students recitation periods collaboratively solving the worksheet problems on whiteboards. When COVID-19 forced the rapidmore »transition to online teaching, these ACL efforts faced an array of challenges. Faculty and GTA reflections on the changes to teaching and learning provide insight into how instructional staff can be supported in implementing ACL across various modes of instruction. The calculus teaching change efforts discussed in this paper are part of an NSF-supported project that aims to make ACL the default method of instruction in highly enrolled gateway STEM courses across the institution. The theoretical framework for the project builds on existing work on grassroots change in higher education (Kezar and Lester, 2011) to study the effect of communities of practice on changing teaching culture. The project uses course-based communities of practice (Wenger, 1999) that include instructors, GTAs, and LAs working together to design and enact teaching change in the targeted courses alongside ongoing professional development for GTAs and LAs. Six faculty and five GTAs involved in the teaching change effort in mathematics were interviewed after the Spring 2020 semester ended. Interview questions focused on faculty and GTA experiences implementing active learning after the rapid transition to online teaching. A grounded coding scheme was used to identify common themes in the challenges faced by instructors and GTAs as they moved online and in the impacts of technology, LA support, and the department community of practice on the move to online teaching. Technology, including both access and capabilities, emerged as a common barrier to student engagement. A particular barrier was students’ reluctance to share video or participate orally in sessions that were being recorded, making group work more difficult than it had been in a physical classroom. In addition, most students lacked access to a tablet for freehand writing, presenting a significant hurdle for sharing mathematical notation when physical whiteboards were no longer an option. These challenges point to the importance of incorporating flexibility in active learning implementation and in the professional development that supports teaching changes toward active learning, since what is conceived for a collaborative physical classroom may be implemented in a much different environment. The full paper will present a detailed analysis of the data to better understand how faculty and GTA experiences in the transition to online delivery can inform planning and professional development as the larger institutional change effort moves forward both in mathematics and in other STEM fields.« less
4. Exploring the Evolution of Engineering Students™ Feelings of Inclusion in Their College and the Broader Scientific Community

   Melissa Lynn Morris, University of ; Joseph Dygert, West Virginia ; Robin A.M Hensel, West Virginia ( July 2021 , 2021 ASEE Virtual Annual Conference Content Access, Virtual Conference)

   This complete research paper discusses how students’ feelings of inclusion change throughout their undergraduate career. Student responses acquired through focus groups and one-on-one interviews were examined to determine how included the students felt in their engineering college and also the broader scientific community. A small group of non-calculus ready engineering students enrolled in a large land grant institution in the Mid-Atlantic region consented to participate in the study. The student cohort participated in an NSF S-STEM funded program aimed at fostering a sense of inclusion in engineering by implementing a curriculum focused on cohort formation, career exploration, and professional development.more »The AcES, consisting of a weeklong pre-fall bridge experience, two common courses, and a variety of co-curricular activities, has been operating for eight years. Students who receive S-STEM funded scholarships participate in three focus groups and two one-on-one interviews each semester throughout their undergraduate studies. Student responses from the one-on-one interviews and focus groups conducted from 2017-2020 were examined with qualitative coding methods. Questions examined in this work include: 1) Did the engineering in history course help make you feel like you belong in engineering at WVU and that you are included in engineering at WVU?, 2) Do you feel part of the group when working on projects in your engineering courses?, 3) Do you consider yourself a member of the scientific and engineering community here at WVU? Why or why not, and 4) Do you consider yourself a member of the broader scientific and engineering community? During the exploratory coding phase three codes were established to represent the degree of inclusion felt by students: Edge of Inclusion, Slight Inclusion, and Feelings of Inclusion. Edge of Inclusion was characterized by student responses such as “almost there but not totally”, “just starting to be”, and “no, well maybe a bit” while student responses such as “yes, but only a little” and “in some classes or situations” were recognized as Slight Inclusion. Examples of student responses such as “yes, I do feel part of it”, “absolutely, since I’ve…”, and “I would consider myself part of . . .” were classified with the code Feelings of Inclusion. Since the sample size was limited by scholarship funding, statistically significant results weren’t obtainable, but clear themes emerged that can be used to influence engineering curricula and serve as justification for an expanded study. Participating in an internship emerged as a major contributor to students feeling included in the broader scientific community. Interestingly, a decrease in the average degree of inclusion occurred after the students’ first semester, prior to increasing in later semesters. It is hypothesized that the emphasis on cohort formation, career exploration, and planned co-curricular activities during the first semester in the AcES program bolstered the initial feelings of inclusion. A student’s feeling of inclusion is known to be a contributing factor in retention. The findings of this research indicate that internships should not only be strongly encouraged, but university resources should be invested in helping students be prepared for, apply to, and obtain internships. The researchers suggest the study be expanded beyond the AcES program to examine a broader sample and greater number of students.« less
5. Diversity and Inclusion in Engineering: Students’ Perceptions of Learning and Engaging with Difference

   Eddington, S. M. ; Zoltowski, C. B. ; Brightman, A. O. ; Joshi, R. ; Buzzanell, P. M. ; Torres, D. ( June 2018 , ASEE annual conference & exposition proceedings)

   This project explores how engineering students understand diversity and inclusion within their engineering programs, and how these understandings are shaped by aspects of the environment in which they are situated. Our study is a component of a broader research project that is examining the seemingly intractable problems of diversity and inclusion that emerge through the converging threads of formation of professional identity and culture of engineering disciplines. In this study we utilized a qualitative analysis of interview data to explore the undergraduate students’ perceptions of diversity and inclusion within the School of Electrical and Computer Engineering (ECE) at Purdue Universitymore »[1]. Our interview draws upon cultural dimensions of engineering disciplines that encourage student to reflect upon and assess diversity and inclusion efforts within ECE [2]. To interrogate students’ perceptions of diversity and inclusion, we interviewed 13 current or past undergraduate ECE students. With nearly 40 percent of the undergraduate ECE students identifying as international students, such a significant international population poses tremendous learning opportunities as well as challenges related to diversity and inclusion. Thus, formal efforts within ECE have been made to bridge cultural differences, develop intercultural competencies, and promote inclusion of internationally and domestically diverse ECE members. However, these efforts have met with mixed results. Our analysis of the interview data suggests that these efforts often were not aligned with literature about how to successfully bridge culture differences in that they lacked an explicit focus on students’ understandings of diversity and inclusion, nor did they provide opportunities for students to reflect on their personal and educational experiences. In what follows, we first examine the framing of scholarship about diversity and inclusion within engineering and then draw upon literature using Kolb’s experiential learning models to illuminate the transformational nature that reflection plays within establishing ways of viewing complex social problems. With this combination and reimagining of reflection as a pathway to more deeply understanding diversity and inclusion, we describe our research methods, data analysis, and the findings from our qualitative analysis. Finally, we conclude with a discussion of the tensions pertaining to difference and sameness that emerged through our analysis. Namely, formal efforts within ECE required both scaffolding and intentionality. Without proper facilitation, the central role that diversity and inclusion plays within professional formation appeared forced, created more cultural isolation, or students ignored these efforts altogether to complete assignments. We conclude by offering both theoretical and pragmatic implications for engineering curriculum.« less
