This paper reports on the development of a second-year design course intended to support student design capabilities in a coherent four-year design thread across an Electrical and Computer Engineering (ECE) curriculum. At Bucknell University students take four years of design starting by building an Internet of Things (IoT) sensor module in first year, a robust IoT product in the second year, using the product to address societal challenges in the third year, followed by a culminating capstone experience in the fourth year. While the first year introduces students broadly to the ECE curriculum, the second-year course reported here is designed to provide students’ abilities in electronic device fabrication and test and measurement, areas students at Bucknell have had little previous exposure to. This course is designed to anchor the remainder of the design sequence by giving all students the capability to independently fabricate and test robust electronic devices.
The second-year course has students individually build an IoT appliance—the Digital / Analog Modular Neopixel-based Electronic Display, or DAMNED project—by going through twelve sequential steps of design from simulation through PCB layout, device and enclosure fabrication, to application development. Because this course is most students’ first encounter with electronic fabrication and test and measurement techniques, the course has students build the project in twelve steps. Each weekly step is heavily scaffolded to allow students to work independently out of class. The paper discusses how such scaffolding is supported through design representations such as block diagrams, pre-class preparation, rapid feedback, and the use of campus makerspaces and educational software tools. The paper also shares results of making iterative improvement to the course structure using action research, and early indications that students are able transfer skills into subsequent design courses.

Makerspaces vs. engineering shops: initial undergraduate student perspectives
Makerspaces are a growing trend in engineering and STEM (Science, Technology, Engineering and Math) education at both the university and K-12 levels. These spaces
which, in theory, are characterized by a community of likeminded individuals interested in digital fabrication and innovative design, are argued to provide opportunities to foster the skills sets critical to the next generation of engineers and scientists. However, spaces
for making are not new to the engineering curriculum as many engineering programs have well-established machine shops orbproject labs that students utilize to complete course projects. In this work-in-progress exploratory study, the authors evaluated early undergraduate students’ perceptions of two contrasting spaces, a contemporary makerspace and a traditional engineering shop. As part of an Introduction to Engineering course, students were asked to visit the two campus spaces, identify important
equipment and policies they noticed in each space, and describe their perception of how the spaces were similar or different. Based on our initial findings, we speculate that access and safety issues in engineering shops may limit their use by early year
engineering undergraduates. Alternatively, digital fabrication technologies and community culture in makerspaces can provide access to a hands-on prototyping and collaborative learning environment for early year engineering students.

null (Ed.)Classes involving physical making were severely disrupted by COVID-19. As workshops, makerspaces, and fab labs shut down in Spring 2020, instructors developed new models for teaching physical prototyping, electronics production, and digital fabrication at a distance. Instructors shipped materials and equipment directly to students, converted makerspaces to job-shops, and substituted low-tech construction methods and hobbyist equipment for industrial tools. The experiences of students and instructors during the pandemic highlighted new learning opportunities when making outside the makerspace. Simultaneously, the shutdown raised new questions on the limits of remote learning for digital fabrication, electronics, and manual craft. This panel brings together experts in making to discuss their experiences teaching physical production in art, design, and engineering during the pandemic. Panelists will discuss their teaching strategies, describe what worked and what did not, and argue for how we can best support students learning hands-on skills going forward.more » « less

Engineering identity development is crucial for engineers’ professional performance, personal fulfillment, and organization’s success. Various factors including recognition by others, interest, and competence can affect the development of engineering identity. Participation in engineering-related activities, such as involvement in makerspaces, can lead to increases in engineering self-efficacy and can provide opportunities for students’ to be recognized as engineers, potentially promoting the development of their engineering identity. However, participation in makerspaces is not necessarily equal across all student groups, with the potential for white, man-dominated cultures of engineering to be replicated in makerspaces, preventing students from marginalized groups from feeling welcome or participating. Earning microcredentials and digital badges in makerspaces has the potential to encourage participation and provide a means for recognition. The goal of this two-year project (funded by NSF’s PFE: Research Initiation in Engineering Formation program) is to study engineering students’ engineering identity development and how makerspaces and digital badges can contribute to this development process. Towards this goal, we interviewed a diverse cohort of eight first-year engineering students at a large, land-grant, Hispanic-Serving Institution in the U.S. during the Fall 2022 semester. Students participated in two one-hour interviews at the start and end of the semester on topics including their making skills, experiences in the makerspace, participation level in groups, perceived recognition as engineers, and feeling of belongingness in the engineering community and makerspaces. This paper presents lessons-learned from the interview implementation process, including dealing with disruptions from the ongoing pandemic and traumatic campus events. We also present emerging themes from qualitative analysis of the interviews. We expect the implications of this work to guide instructors and administrators in developing more motivating and interactive engineering courses and makerspace experiences for diverse students.more » « less

null (Ed.)Digital fabrication courses that relied on physical makerspaces were severely disrupted by COVID-19. As universities shut down in Spring 2020, instructors developed new models for digital fabrication at a distance. Through interviews with faculty and students and examination of course materials, we recount the experiences of eight remote digital fabrication courses. We found that learning with hobbyist equipment and online social networks could emulate using industrial equipment in shared workshops. Furthermore, at-home digital fabrication offered unique learning opportunities including more iteration, machine tuning, and maintenance. These opportunities depended on new forms of labor and varied based on student living situations. Our findings have implications for remote and in-person digital fabrication instruction. They indicate how access to tools was important, but not as critical as providing opportunities for iteration; they show how remote fabrication exacerbated student inequities; and they suggest strategies for evaluating trade-offs in remote fabrication models with respect to learning objectives.more » « less

Thought must be given to how individuals from underrepresented groups (URGs) conceptualize their academic engineering identities. Black male students have been shown to face a great challenge in integrating their racial identification into their self-concept. This “balancing act” involves the navigation and negotiation between multiple social spaces. The establishment of a positive identity associated with engineering is critical to how underrepresented students establish their sense of agency and overall “fit” within the institutional and/or professional setting. Yet, because of low numbers in participant populations, many studies fail to disaggregate the experiences of individuals from URGs. Further, if makerspaces represent an avenue of hope for fostering a generation of makers and innovative thinkers prepared to address the needs and challenges of our society, it is quite plausible that without careful attention we could be building another exclusionary system through makerspaces, grounded in the acceptance of Caucasian, male experiences and perceptions as the status quo. As making could potentially impact academic progression, through early exposure and opportunities to develop confidence through building, design, iteration and community, it is critical that we understand how all students, especially those from underrepresented groups, come to affiliate with, become alienated from and/or negotiate the cultural norms within these maker communities. To achieve this, it is necessary to explore the complexities of underrepresented students’ identity development. This study investigated the experiences of Black male engineering students that have also engaged in university-affiliated makerspaces as makers. Seven Black male students from a range of institution types, including Predominantly White Institutions (PWIs), Historically Black Colleges and Universities (HBCUs) and Asian American Native American Pacific Islander Institutions (AANAPI), participated in narrative interviews to ascertain stories of their personal growth and identity development. Engaging in makerspaces was found to promote agency and engineering identity for Black male undergraduates; however, makerspaces located at PWIs were found to reflect the heteronormative culture of engineering in a way that challenged smooth navigation in and through these spaces for Black men.more » « less
