   Synopsis Science education is most effective when it provides authentic experiences that reflect professional practices and approaches that address issues relevant to students’ lives and communities. Such educational experiences are becoming increasingly interdisciplinary and can be enhanced using digital fabrication. Digital fabrication is the process of designing objects for the purpose of fabricating with machinery such as 3D-printers, laser cutters, and Computer Numerical Control (CNC) machines. Historically, these types of tools have been exceptionally costly and difficult to access; however, recent advancements in technological design have been accompanied by decreasing prices. In this review, we first establish the historical and theoretical foundations that support the use of digital fabrication as a pedagogical strategy to enhance learning. We specifically chose to focus attention on 3D-printing because this type of technology is becoming increasingly advanced, affordable, and widely available. We systematically reviewed the last 20 years of literature that characterized the use of 3D-printing in biological education, only finding a total of 13 articles that attempted to investigate the benefits for student learning. While the pedagogical value of student-driven creation is strongly supported by educational literature, it was challenging to make broad claims about student learning in relation to using or creating 3D-printed models in the context of biological education. Additional studies are needed to systematically investigate the impact of student-driven creation at the intersection of biology and engineering or computer science education.

   Spatial reasoning skills contribute to performance in many STEM fields. For example, drawing sectional views of three-dimensional objects is an essential skill for engineering students. There is considerable variation in the spatial reasoning skills of prospective engineering students, putting some at risk for compromised performance in their classes. This study takes place in a first-year engineering Spatial Visualization course to integrate recent practices in engineering design education with cognitive psychology research on the nature of spatial learning. We employed three main pedagogical strategies in the course - 1) in class instruction on sketching; 2) spatial visualization training; and 3) manipulation of physical objects (CAD/3D print creations). This course endeavors to use current technology, online accessibility, and implementation of the three pedagogical strategies to bring about student growth in spatial reasoning. This study is designed to determine the effect of adding two different spatial reasoning training apps to this environment. Over 230 students (three sections) participated in our study. In two of the three sections, students received interactive spatial visualization training using either a spatial visualization mobile touchscreen app in one section or an Augmented Reality (AR) app in the other section. Research suggests that there are benefits to using the Spatial Vis Classroom mobile app for college students.The app has been shown to increase student persistence resulting in large learning gains as measured by the Purdue assessment of spatial visualization (PSVT-R), especially for students starting with poor spatial visualization skills. The Spatial Vis Classroom app can be used in the classroom or assigned as homework. The AR app is designed to help users develop their mental rotation abilities. It is designed to support a holistic understanding of 3-dimensional objects, and research has shown that, in combination with a traditional curriculum, it increases students’ abilities also measured by the PSVT-R. Of particular interest, the data suggest that the app overcomes the advantage found by males over females in a traditional class alone focused on spatial reasoning. Both of the course sections were required to use the apps for approximately the same time in class and outside of class. Students in the control section were required to do hand sketching activities in class and outside of class, with roughly the same completion time as for the sections with the apps. Students grades were not affected by using the three different approaches as grading was based on completion only. Based on current literature, we hypothesize that overall benefits (PSVT-R gains) will be comparable across the 3 treatments but there will be different effects on attitude and engagement (confidence,enjoyment, and self-efficacy). Lastly, we hypothesize that the treatments will have different effects on male/female and ethnic categories of the study participants. The final paper will include an analysis of results and a report of the findings.

3. A methodological approach for researching online teacher professional development

   Johnson, M. M. ( April 2021 , Middle Atlantic ASEE Section Spring 2021 Conference)

   null (Ed.)

   COVID-19 has altered the landscape of teaching and learning. For those in in-service teacher education, workshops have been suspended causing programs to adapt their professional development to a virtual space to avoid indefinite postponement or cancellation. This paradigm shift in the way we conduct learning experiences creates several logistical and pedagogical challenges but also presents an important opportunity to conduct research about how learning happens in these new environments. This paper describes the approach we took to conduct research in a series of virtual workshops aimed at teaching rural elementary teachers about engineering practices and how to teach a unit from an engineering curriculum. Our work explores how engineering concepts and practices are socially constructed through interactions with teachers, students, and artifacts. This approach, called interactional ethnography has been used by the authors and others to learn about engineering teaching and learning in precollege classrooms. The approach relies on collecting data during instruction, such as video and audio recordings, interviews, and artifacts such as journal entries and photos of physical designs. Findings are triangulated by analyzing these data sources. This methodology was going to be applied in an in-person engineering education workshop for rural elementary teachers, however the pandemic forced us to conduct the workshops remotely. Teachers, working in pairs, were sent workshop supplies, and worked together during the training series that took place over Zoom over four days for four hours each session. The paper describes how we collected video and audio of teachers and the facilitators both in whole group and in breakout rooms. Class materials and submissions of photos and evaluations were managed using Google Classroom. Teachers took photos of their work and scanned written materials and submitted them all by email. Slide decks were shared by the users and their group responses were collected in real time. Workshop evaluations were collected after each meeting using Google Forms. Evaluation data suggest that the teachers were engaged by the experience, learned significantly about engineering concepts and the knowledge-producing practices of engineers, and feel confident about applying engineering activities in their classrooms. This methodology should be of interest to the membership for three distinct reasons. First, remote instruction is a reality in the near-term but will likely persist in some form. Although many of us prefer to teach in person, remote learning allows us to reach many more participants, including those living in remote and rural areas who cannot easily attend in-person sessions with engineering educators, so it benefits the field to learn how to teach effectively in this way. Second, it describes an emerging approach to engineering education research. Interactional ethnography has been applied in precollege classrooms, but this paper demonstrates how it can also be used in teacher professional development contexts. Third, based on our application of interactional ethnography to an education setting, readers will learn specifically about how to use online collaborative software and how to collect and organize data sources for research purposes.

4. Investigating Factors that Predict Academic Success in Engineering and Computer Science

   Adesope, O. ; Sunday, O.J. ; Ewumi, E.R. ; Minichiello, A. ; Asghar, M. ; Claiborn, C.S. ( July 2021 , 2021 ASEE Virtual Annual Conference)

   Over the years, researchers have found that student engagement facilitates desired academic success outcomes for college undergraduate students. Much research on student engagement has focused on academic tasks and classroom context. High impact engagement practices (HIEP) have been shown to be effective for undergraduate student academic success. However, less is known about the effects of HIEP specifically on engineering and computer science (E/CS) student outcomes. Given the high attrition rates for E/CS students, student involvement in HIEP could be effective in improving student outcomes for E/CS students, including those from various underrepresented groups. More generally, student participation in specific HIEP activities has been shown to shape their everyday experiences in school, both academically and socially. Hence, the primary goal of this study is to examine the factors that predict academic success in E/CS using multiple regression analysis. Specifically, this study seeks to understand the effects of high impact engagement practices (HIEP), coursework enjoyability, confidence at completing a degree on academic success of the underrepresented and nontraditional E/CS students. We used exploratory factor analyses to derive “academic success” variable from five items that sought to measure how students persevere to attain academic goals. A secondary goal of the present study is to address the gap in research literature concerning how participation in HIEP affects student persistence and success in E/CS degree programs. Our research team developed and administered an online survey to investigate and identify factors that affect participation in HIEP among underrepresented and nontraditional E/CS students. Respondents (N = 531) were students enrolled in two land grant universities in the Western U.S. Multiple regression analyses were conducted to examine the proportion of the variation in the dependent variable (academic success) explained by the independent variables (i.e., high impact engagement practice (HIEP), coursework enjoyability, and confidence at completing a degree). We hypothesized that (1) high impact engagement practices will predict academic success; (2) coursework enjoyability will predict academic success; and (3) confidence at completing a degree will predict academic success. Results showed that the multiple regression model statistically predicted academic success , F(3, 270) = 33.064, p = .001, adjusted R2 = .27. This results indicate that there is a linear relationship in the population and the multiple regression model is a good fit for the data. Further, findings show that confidence at completing a degree is significantly predictive of academic success. In addition, coursework enjoyability is a strong predictor of academic success. Specifically, the result shows that an increase in high impact engagement activity is associated with an increase in students’ academic success. In sum, these findings suggest that student participation in High Impact Engagement Practices might improve academic success and course retention. Theoretical and practical implications are discussed.

   This paper describes an evidence based-practice paper to a formative response to the engineering faculty and students’ needs at Anonymous University. Within two weeks, the pandemic forced the vast majority of the 1.5 million faculty and 20 million students nationwide to transition all courses from face-to-face to entirely online. Never in the history of higher education has there been a concerted effort to adapt so quickly and radically, nor have we had the technology to facilitate such a rapid and massive change. At Anonymous University, over 700 engineering educators were racing to transition their courses. Many of those faculty had never experienced online course preparation, much less taught one synchronously or asynchronously. Faculty development centers and technology specialists across the university made a great effort to aid educators in this transition. These educators had questions about the best practices for moving online, how their students were affected, and the best ways to engage their students. However, these faculty’s detailed questions were answerable only by faculty peers’ experience, students’ feedback, and advice from experts in relevant engineering education research-based practices. This paper describes rapid, continuous, and formative feedback provided by the Engineering Education Faculty Group (EEFG) to provide an immediate response for peer faculty guidance during the pandemic, creating a community of practice. The faculty membership spans multiple colleges in the university, including engineering, education, and liberal arts. The EEFG transitioned immediately to weekly meetings focused on the rapidly changing needs of their colleagues. Two surveys were generated rapidly by Hammond et al. to characterize student and faculty concerns and needs in March of 2020 and were distributed through various means and media. Survey 1 and 2 had 3381 and 1506 respondents respectively with most being students, with 113 faculty respondents in survey 1, the focus of this piece of work. The first survey was disseminated as aggregated data to the College of Engineering faculty with suggested modifications to course structures based on these findings. The EEFG continued to meet and collaborate during the remainder of the Spring 2020 semester and has continued through to this day. This group has acted as a hub for teaching innovation in remote online pedagogy and techniques, while also operating as a support structure for members of the group, aiding those members with training in teaching tools, discussion difficult current events, and various challenges they are facing in their professional teaching lives. While the aggregated data gathered from the surveys developed by Hammond et al. was useful beyond measure in the early weeks of the pandemic, little attention at the time was given to the responses of faculty to that survey. The focus of this work has been to characterize faculty perceptions at the beginning of the pandemic and compare those responses between engineering and non-engineering faculty respondents, while also comparing reported perceptions of pre- and post-transition to remote online teaching. Interviews were conducted between 4 members of the EEFG with the goal of characterizing some of the experiences they have had while being members of the group during the time of the pandemic utilizing Grounded theory qualitative analysis.
