   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.

2. Using badging to promote makerspace participation and engineering identity development: Emergent themes and lessons learned from a pilot

   Bushra, Jannatul ; Budinoff, Hannah ; Shivers-McNair, Ann ; Berger, Edward ( January 2023 , Proceedings of the ASEE Annual Conference and Exposition)

   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.

   There has been dramatic growth in the number of makerspaces at educational institutions. More research is needed to understand student interactions in these spaces and how these spaces should be designed to support student learning. This project uses network analysis techniques to study the network of activities in a makerspace that lead to successful student experiences. The proposed analyses will model a makerspace as a network of interactions between equipment, staff, and students. Results from this study will help educators to 1) identify and remove previously unknown hurdles for students who rarely use the space, 2) design an effective space using limited resources, 3) understand the impact of new equipment or staff, and 4) create learning opportunities such as workshops and curriculum integration that increase student learning. The new knowledge produced by this project may be useful for maximizing equipment and support infrastructure, and for guiding new equipment purchases. Thus, the results will support further development of effective makerspaces. This project hypothesizes that network-level analyses and metrics can provide valuable insights into student learning in makerspaces and will support what-if scenarios for proposed changes in spaces. Systems modeling and analysis have been used successfully to understand complex human and biological networks. In the context of makerspaces, this technique will provide measures of interaction between system components such as students, staff, and equipment. The analyses will identify the system components that are frequently used when students work in the makerspace over multiple visits. The project will allow for the comparison of makerspaces that have different levels of integration with the curriculum and methods of student introduction (pop-up classes, tours, extra-curricular competitions, advertising, and bring a friend). Demonstration of the effectiveness of the analyses in characterizing makerspaces and the ease of data collection will help support the use of this approach in future work that compares makerspaces nationwide. Current results explore the order in which students choose to learn and use the tools in the space, which tools/features are used most frequently and how the data from the daily entry/exit surveys compares to the end-of-semester self-reports. A key question in this research, especially for making it adoptable by other universities, is if end-of-semester, self-reported data is accurate enough to create informative, actionable guidance from the network models without requiring the daily tool usage data.

4. Makerspaces vs. engineering shops: initial undergraduate student perspectives

   Youmans, Kate ; Villanueva, Idalis ; Nadelson, Louis ; Lenz, Adam ( October 2018 , IEEE Frontiers in Education Conference)

   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.

5. Developing Best Practices for Teaching Scientific Documentation: Toward a Better Understanding of How Lab Notebooks Contribute to Knowledge-building in Engineering Design and Experimentation

   Laboratory notebooks perform important roles in the engineering disciplines. They at once record an engineer’s work, serve as an important reference for future reports and/or articles, and perform as a kind of journal that enables questioning presuppositions, considering new approaches, and generating new ideas. Given the importance of notebooks, there is surprisingly little scholarship on how to teach their use. Stanley and Lewandowski (2016) surveyed students in undergraduate laboratory courses and evaluated how their notebooks were being used. They found that “few [students] … thought that their lab classes successfully taught them the benefit of maintaining a lab notebook.” Moreover, the authors’ later survey of the literature and of college faculty led them to conclude that in undergraduate lab courses “little formal attention has been paid to addressing what is considered ‘best practice’ for scientific documentation …[or] how researchers come to learn these practices” (Stanley and Lewandowski, 2018). At XXX University, two courses, Interfacing the Digital Domain with the Analog World (AEP 2640) and Engineering Communications (ENGRC 2640) are taught in conjunction. In AEP 2640, students use a computer to control equipment and acquire measurements in an engineering design and experimentation laboratory. Laboratory activities such as the development of a computer interface for an oscilloscope, a set of motors, and a photodiode culminate in the realization of an automated laser scanning microscope system. In ENGRC 2640, students receive instruction and feedback on their lab notebook entries and, in turn, use those notebooks as a resource for preparing a Progress Report and an Instrument Design Report. The instructors encourage peer review in order to facilitate improvement of students’ skills in the art of notebook use while allowing them to develop these skills and personal style through trial and error during the research. The primary learning objectives are: 1) to enable students to engage in real laboratory research; and 2) to develop proficiency with select genres associated with that research. The educational research objectives are: 1) to study students’ developing proficiency in order to generate best practices for teaching and learning scientific documentation; and 2) to better understand the contribution of scientific documentation to the teaching and learning of authentic research. This study is a work-in-progress. We will present the study design. That design involves, first, developing a self-efficacy scale for both conducting laboratory research and performing those genres associated with that research. Self-efficacy or a “person’s awareness of their ability to accomplish a goal” (Kolar et. al, 2013) has proven to be a powerful predictor of achievement. Our intent is to track learner agency. Second, the design also involves conducting a content analysis of students’ laboratory notebooks and reports. Content analysis is a methodology that encourages inferencing "across distinct domains, from particulars of one kind to particulars of another kind" (Krippendorff,, 2019). Our intent is to learn about students' mastery of the engineering design and experimentation process through analyzing their lab notebooks. We will present the results of a preliminary content analysis of a select sample of those notebooks and genres.
