ABSTRACT Traditional lecture-centered approaches alone are inadequate for preparing students for the challenges of creative problem solving in the STEM disciplines. As an alternative, learnercentered and other high-impact pedagogies are gaining prominence. The Wabash College 3D Printing and Fabrication Center (3D-PFC) supports several initiatives on campus, but one of the most successful is a computer-aided design (CAD) and fabrication-based undergraduate research internship program. The first cohort of four students participated in an eight-week program during the summer of 2015. A second group of the four students was successfully recruited to participate the following summer. This intensive materials science research experience challenged students to employ digital design and fabrication in the design, testing, and construction of inexpensive scientific instrumentation for use in introductory STEM courses at Wabash College. The student research interns ultimately produced a variety of successful new designs that could be produced for less than $25 per device and successfully detect analytes of interest down to concentrations in the parts per million (ppm) range. These student-produced instruments have enabled innovations in the way introductory instrumental analysis is taught on campus. Beyond summer work, the 3D-PFC staffed student interns during the academic year, where they collaborated on various cross-disciplinary projects with students and faculty from departments such as mathematics, physics, biology, rhetoric, history, classics, and English. Thus far, the student work has led to three campus presentations, four presentations at national professional conferences, and three peer-reviewed publications. The following report highlights initial progress as well as preliminary assessment findings.

Active Learning and Student Engagement via 3D Printing and Design: Integrating Undergraduate Research, Service Learning, and Cross-Disciplinary Collaborations
ABSTRACT In order to provide students with the training required to meet the substantial and diverse challenges of the 21 st Century, effective programs in engineering, science, and technology must continue to take the lead in developing high-impact educational practices. Over the past year, faculty across several departments collaborated in the establishment of a campus 3D printing and fabrication center. This facility was founded to offer opportunities for exploring innovative active learning strategies in order to enhance the lives of Wabash College students and serve as a model to other institutions of higher education. This campus resource provides the infrastructure that will empower faculty and staff to explore diverse and meaningful cross-disciplinary collaborations related to teaching and learning across campus. New initiatives include the development of courses on design and fabrication, collaborative cross-disciplinary projects that bridge courses in the arts and sciences, 3D printing and fabrication-based undergraduate research internships, and entrepreneurial collaborations with local industry. These innovative approaches are meant to open the door to greater active learning experiences that empower and prepare students for creative and practical problem solving. Furthermore, service learning projects, community-based opportunities, and global outreach initiatives provide students with a sense of social responsibility, ethical awareness, leadership, and teamwork. This paper shares initial successes of this effort and goals for future enrichment of student learning.

Marshall, Pamela Ann (Ed.)ABSTRACT The initial phase of the COVID-19 pandemic changed the nature of course delivery from largely in-person to exclusively remote, thus disrupting the well-established pedagogy of the Genomics Education Partnership (GEP; https://www.thegep.org ). However, our web-based research adapted well to the remote learning environment. As usual, students who engaged in the GEP’s Course-based Undergraduate Research Experience (CURE) received digital projects based on genetic information within assembled Drosophila genomes. Adaptations for remote implementation included moving new member faculty training and peer Teaching Assistant office hours from in-person to online. Surprisingly, our faculty membership significantly increased and, hence, the number of supported students. Furthermore, despite the mostly virtual instruction of the 2020–2021 academic year, there was no significant decline in student learning nor attitudes. Based on successfully expanding the GEP CURE within a virtual learning environment, we provide four strategic lessons we infer toward democratizing science education. First, it appears that increasing access to scientific research and professional development opportunities by supporting virtual, cost-free attendance at national conferences attracts more faculty members to educational initiatives. Second, we observed that transitioning new member training to an online platform removed geographical barriers, reducing time and travel demands, and increased access for diverse faculty to join. Third, developing a Virtual Teaching Assistant program increased the availability of peer support, thereby improving the opportunities for student success. Finally, increasing access to web-based technology is critical for providing equitable opportunities for marginalized students to fully participate in research courses. Online CUREs have great potential for democratizing science education.more » « less

Abstract BackgroundThe University of California system has a novel tenure-track education-focused faculty position called Lecturer with Security of Employment (working titles: Teaching Professor or Professor of Teaching). We focus on the potential difference in implementation of active-learning strategies by faculty type, including tenure-track education-focused faculty, tenure-track research-focused faculty, and non-tenure-track lecturers. In addition, we consider other instructor characteristics (faculty rank, years of teaching, and gender) and classroom characteristics (campus, discipline, and class size). We use a robust clustering algorithm to determine the number of clusters, identify instructors using active learning, and to understand the instructor and classroom characteristics in relation to the adoption of active-learning strategies. ResultsWe observed 125 science, technology, engineering, and mathematics (STEM) undergraduate courses at three University of California campuses using the Classroom Observation Protocol for Undergraduate STEM to examine active-learning strategies implemented in the classroom. Tenure-track education-focused faculty are more likely to teach with active-learning strategies compared to tenure-track research-focused faculty. Instructor and classroom characteristics that are also related to active learning include campus, discipline, and class size. The campus with initiatives and programs to support undergraduate STEM education is more likely to have instructors who adopt active-learning strategies. There is no difference in instructors in the Biological Sciences, Engineering, or Information and Computer Sciences disciplines who teach actively. However, instructors in the Physical Sciences are less likely to teach actively. Smaller class sizes also tend to have instructors who teach more actively. ConclusionsThe novel tenure-track education-focused faculty position within the University of California system represents a formal structure that results in higher adoption of active-learning strategies in undergraduate STEM education. Campus context and evolving expectations of the position (faculty rank) contribute to the symbols related to learning and teaching that correlate with differential implementation of active learning.more » « less

Abstract Limited resources available to the engineering faculty and students impede student learning and deep understanding of the material that is presented in the dynamics and mechanical vibrations courses. Active learning practices such as learning by doing is an effective way to not only build a solid foundation in knowledge but also help students develop engineering skills. However, these courses are mainly taught in a traditional manner and many students struggle in connecting the theory to its real-world application and lose interest. Although mechanical engineering students get more hands-on opportunities in the laboratories, they take vibrations and control laboratories in the following semesters since vibrations is a pre-requisite for these labs. To address this issue, we designed 3 low-cost, compact, and portable laboratory equipment and fabricated them using 3D printing technology. The first equipment is a 3-pendulum system with different lengths and tip loads that can be utilized in the engineering dynamics course. While the second equipment is a 2 DOF compliant vibration isolator consisting of flexible beams, masses, and a linear actuator, the third equipment is a non-linear cantilever beam to be utilized in the vibrations courses and their associated laboratories.more » « less

Campus agriculture projects are increasingly being recognized as spaces impactful to student engagement and learning through curricular and co-curricular programming; however, most campus farm activities are limited to agriculture or sustainability programs and/or cocurricular student clubs. Thus, campus farms are largely underutilized in the undergraduate curriculum, marking a need to explore the efficacy and impact of engaging a diverse array of disciplinary courses in the rich social, environmental, and civic context of local sustainable agriculture. The Farm Hub program presented here incentivizes instructors to refocus a portion of existing course content around the topic of local, sustainable agriculture, and reduces barriers to using a campus farm as a situated learning context for curricula. A pedagogical framework founded in place-based experiential learning (PBEL) theory was developed to guide instructors in the development and implementation of 4–6-week inquiry-based PBEL modules embedded in existing courses. The framework was converted into a research protocol to quantify program implementation fidelity and PBEL best practice adherence for the proposed lesson plans (intended) and their implementation (applied). The framework enables the development of a cohesive cross-curricular program so that the impact of implementation fidelity and best practice adherence to student learning outcomes in scientific literacy, place attachment and meaning, and civic mindedness can be assessed and the results utilized to develop a formal farm-situated PBEL pedagogical taxonomy. This framework can be applied to PBEL curriculum in natural spaces beyond campus farms.more » « less
