   Howland Cummings, M.; Darbeheshti, M.; Ivey, S.; Stewart, C.; Russomanno, D.; King, D.; Goodman, K.; Campbell, J.; Altman, T.; Jacobson, M.; et al (August 2022, ASEE Annual Conference proceedings)

   This Complete Evidence-based Practice paper will describe how three different public urban research universities designed, executed, and iterated Summer Bridge programming for a subset of incoming first-year engineering students over the course of three consecutive years. There were commonalities between each institution’s Summer Bridge, as well as unique aspects catering to the specific needs and structures of each institution. Both these commonalities and unique aspects will be discussed, in addition to the processes of iteration and improvement, target student populations, and reported student outcomes. Finally, recommendations for other institutions seeking to launch or refine similar programming will be shared. Summer Bridge programming at each of the three institutions shared certain communalities. Mostly notably, each of the three institutions developed its Summer Bridge as an additional way to provide support for students receiving an NSF S-STEM scholarship. The purpose of each Summer Bridge was to build community among these students, prepare them for the academic rigor of first-year engineering curriculum, and edify their STEM identity and sense of belonging. Each Summer Bridge was a 3-5 day experience held in the week immediately prior to the start of the Fall semester. In addition to these communalities, each Summer Bridge also had its own unique features. At the first institution, Summer Bridge is focused on increasing college readiness through the transition from summer break into impending coursework. This institution’s Summer Bridge includes STEM special-interest presentations (such as biomedical or electrical engineering) and other development activities (such as communication and growth mindset workshops). Additionally, this institution’s Summer Bridge continues into the fall semester via a 1-credit hour First Year Seminar class, which builds and reinforces student networking and community beyond the summer experience. At the second institution, all students receiving the NSF S-STEM scholarship (not only those who are first-year students) participate in Summer Bridge. This means that S-STEM scholars at this institution participate in Summer Bridge multiple years in a row. Relatedly, after the first year, Summer Bridge transitioned to a student-led and student-delivered program, affording sophomore and junior students leadership opportunities, which not only serve as marketable experience after graduation, but also further builds their sense of STEM identity and belonging. At the third institution, a special focus was given to building community. This was achieved through several means. First, each day of Summer Bridge included a unique team-oriented design challenge where students got to work together and know each other within an engineering context, also reinforcing their STEM identities. Second, students at this institution’s Summer Bridge met their future instructors in an informal, conversational, lunch setting; many students reported this was one of their favorite aspects of Summer Bridge. Finally, Summer Bridge facilitated a first connect between incoming first-year students and their peer mentors (sophomore and junior students also receiving the NSF S-STEM scholarship), with whom they would meet regularly throughout the following fall and spring semesters. Each of the three institutions employed processes of iteration and improvement for their Summer Bridge programming over the course of two or three consecutive years. Through each version and iteration of Summer Bridge, positive student outcomes are demonstrated, including direct student feedback indicating built community among students and the perception that their time spent during Summer Bridge was valuable. Based on the experiences of these three institutions, as well as research on other institutions’ Summer Bridge programming, recommendations for those seeking to launch or refine similar Summer Bridge programming will also be shared.

2. Multi Institutional Collaboration in Additive Manufacturing: Lessons Learned

   https://doi.org/10.18260/1-2--34987  

   Littrell, Michael; Chitiyo, George; Fidan, Ismail; Cossette, Mel; Singer, Thomas; Tackett, Ed. (June 2020, Proceedings of the 2020 ASEE Annual Conference)

   One of the fastest growing fields in the broad field of engineering is Additive Manufacturing (AM), also known as 3D Printing. AM is being used in many fields including, among others, design, STEM, construction, art, and healthcare. Many educational institutions however, do not have the requisite capacity and resources to effectively educate students in this area particularly when it comes to rapid transition from design to small-volume level production. A coalition of several higher education institutions under a National Science Foundation (NSF) funded Advanced Technological Education (ATE) Project has been working towards providing educators with the skills and material resources to effectively teach their students about 3D printing. The ultimate beneficiaries are high school and post-secondary students and include those in vocational fields. Before and during Fall 2019, Train the Trainer Studios (TTS) were conducted to train instructors, drawing participants from many institutions across neighboring states designed to provide hands-on instruction to participants. In addition, Massive Open Online Courses (MOOC) and webinars have also been made available to all participating instructors and other collaborators to openly share the information being generated through this ATE AM coalition. Evaluation of the TTS revealed many positive results, with the participants sharing many success stories after implementing the learned concepts at their institutions. From the evaluation findings, participants were largely satisfied with the delivery and quality of instruction they received from all the TTS presenters, with almost all of them, in all instances, indicating that the training they received would be useful in their programs. The current paper and proposed presentation will report on the lessons learned through this process, including sharing some of the success stories from the instructors and their students.

3. The Earlier the Better? Investigating the Importance of Timing on Effectiveness of Design for Additive Manufacturing Education

   Prabhu, Rohan; Miller, Scarlett R; Simpson, Timothy W; Meisel, Nicholas A (August 2018, Proceedings of the ... ASME Design Engineering Technical Conferences)

   Additive Manufacturing (AM) is a novel process that enables the manufacturing of complex geometries through layer-by-layer deposition of material. AM processes provide a stark contrast to traditional, subtractive manufacturing processes, which has resulted in the emergence of design for additive manufacturing (DfAM) to capitalize on AM’s capabilities. In order to support the increasing use of AM in engineering, it is important to shift from the traditional design for manufacturing and assembly mindset, towards integrating DfAM. To facilitate this, DfAM must be included in the engineering design curriculum in a manner that has the highest impact. While previous research has systematically organized DfAM concepts into process capability-based (opportunistic) and limitation-based (restrictive) considerations, limited research has been conducted on the impact of teaching DfAM on the student’s design process. This study investigates this interaction by comparing two DfAM educational interventions conducted at different points in the academic semester. The two versions are compared by evaluating the students’ perceived utility, change in self-efficacy, and the use of DfAM concepts in design. The results show that introducing DfAM early in the semester when students have little previous experience in AM resulted in the largest gains in students perceiving utility in learning about DfAM concepts and DfAM self-efficacy gains. Further, we see that this increase relates to greater application of opportunistic DfAM concepts in student design ideas in a DfAM challenge. However, no difference was seen in the application of restrictive DfAM concepts between the two interventions. These results can be used to guide the design and implementation of DfAM education.

4. Interactive online lectures for asynchronous delivery

   https://doi.org/10.1088/1742-6596/2297/1/012004  

   Teese, R B; Koenig, K; Maries, A; Chabot, M (June 2022, Journal of Physics: Conference Series)

   Abstract Physics teachers often use active learning techniques such as “clicker questions” in their lectures. We created a set of asynchronous online lectures that include clicker questions. Five instructors created and shared their Interactive Online Lectures for the first semester of an introductory calculus-based course. Each lecture consists of short video lecture segments interspersed with required multiple-choice clicker questions designed to help students understand the content. After submitting an answer, the student sees an explanation of why that answer is right or wrong. Instructors at five institutions used the lectures during the Fall Semester of 2020.

5. Creating and Assessing an Upper Division Additive Manufacturing Course and Laboratory to Enhance Undergraduate Research and Innovation

   https://doi.org/10.18260/1-2--30124  

   Maloney, Patricia A; Li, Bingbing; Zhang, Meng; Cong, Weilong (June 2018, 2018 ASEE Annual Conference & Exposition)

   This NSF IUSE project is on the Exploration and Design Tier and the Engaged Student Learning Track. It is aimed at better preparing the country’s professional workforce in the renaissance of U.S. skilled manufacturing by creating new personnel proficient in additive manufacturing (AM). AM is mainstream; it has the potential to bring jobs back to the U.S. and add to the nation’s global competitiveness. AM is the process of joining materials to make objects from 3D data in a layer upon layer fashion. The objectives are to develop, assess, revise, and disseminate an upper division course and laboratory, “Additive Manufacturing,” and to advance undergraduate and K-12 student research and creative inquiry activities as well as faculty expertise at three diverse participating universities: Texas Tech, California State-Northridge, and Kansas State. This research/pedagogical team contains a mechanical engineering professor at each university to develop and teach the course, as well as a sociologist trained in K-12 outreach, course assessment, and human subjects research to accurately determine the effects on K-12 and undergraduate students. The proposed course will cover extrusion-based, liquid-based, and powder-based AM processes. For each technology, fundamentals, applications, and advances will be discussed. Students will learn solutions to AM of polymers, metals, and ceramics. Two lab projects will be built to provide hands-on experiences on a variety of state-of-the-art 3D printers. To stimulate innovation, students will design, fabricate, and measure test parts, and will perform experiments to explore process limits and tackle real world problems. They will also engage K-12 students through video demonstrations and mentorship, thus developing presentation skills. Through the project, different pedagogical techniques and assessment tools will be utilized to assess and improve engineering education at both the undergraduate and K-12 levels through varied techniques: i) undergraduate module lesson plans that are scalable to K-12 levels, ii) short informational video lessons created by undergraduates for K-12 students with accompanying in-person mentorship activities at local high schools and MakerSpaces, iii) pre- and post-test assessments of undergraduates’ and K-12 participating students’ AM knowledge, skills, and perceptions of self-efficacy, and iv) focus groups to learn about student concerns/learning challenges. We will also track students institutionally and into their early careers to learn about their use of AM technology professionally.
