Problem-solving is a critical skill in the workplace, but recent college graduates are often deficient in problem-solving skills. Introductory STEM courses present engineering students with well-structured problems with single-path solutions that do not prepare students with the problem-solving skills they will need to solve complex problems within authentic engineering contexts. When presented with complex problems in authentic contexts, engineering students find it difficult to transfer the scientific knowledge learned in their STEM courses to solve these integrated and ill structured problems. By integrating physics laboratories with engineering design problems, students are taught to apply physics principles to solve ill-structured and complex engineering problems. The integration of engineering design processes to physics labs is meant to help students transfer physics learning to engineering problems, as well as to transfer the design skills learned in their engineering courses to the physics lab. We hypothesize this integration will help students become better problem solvers when they go out to industry after graduation. The purpose of this study is to examine how students transfer their understanding of physics concepts to solve ill-structured engineering problems by means of an engineering design project in a physics laboratory. We use a case-study methodology to examine two cases and analyze the cases using a lens of co-regulated learning and transfer between physics and engineering contexts. Observations were conducted using transfer lenses. That is, we observed groups during the physics labs for evidence of transfer. The research question for this study was, to what extent do students relate physics concepts with concepts from other materials (classes) through an engineering design project incorporated in a physics laboratory? Teams were observed over the course of 6 weeks as they completed the second design challenge. The cases presented in this study were selected using observations from the lab instructors of the team’s work in the first design project. Two teams, one who performed well, and one that performed poorly, were selected to be observed to provide insight on how students use physics concepts to engage in the design process. The second design challenge asked students to design an eco-friendly way of delivering packages of food to an island located in the middle of the river, which is home to critically endangered species. They are given constraints that the solution cannot disrupt the habitat in any way, nor can the animals come into contact directly with humans or loud noises. Preliminary results indicate that both teams successfully demonstrated transfer between physics and engineering contexts, and integrated physics concepts from multiple labs to complete the design project. Teams that struggle seem to be less connected with the design process at the beginning of the project and are less organized. In contrast, teams that are successful demonstrate greater co-regulated learning (communication, reflection, etc.) and focus on making connections between the physics concepts and principles of engineering design from their engineering course work.

Integrated STEM: Impact of Engineering Design and Computer Science in STEM Labs
By integrating physics laboratories with engineering design and computer science, students apply physics principles to ill-structured and complex problems, engage in knowledge transfer, and gain interest in STEM. The introductory physics labs at Purdue have been updated to include engineering design and computer science principles that ground physics in authentic problems. Integrated labs have been evaluated using student perception post-surveys, student course performance, interviews, and case-study observations. Preliminary results indicate that integrated physics labs promote transfer, enhanced metacognitive skills, student interest, and motivation.

null (Ed.)Research on K-12 integrated STEM settings suggests that engineering design activities play an important role in supporting students’ science learning. Moreover, the National Academies of Sciences, Engineering, and Medicine named improvement in science achievement as an objective of K-12 engineering education. Despite promising findings and the theorized importance of engineering education on science learning, there is little literature that investigates the impact of independent engineering design courses on students’ science learning at the high school level. This sparse exploration motivates our work-in-progress study, which explores the impact of high school students’ exposure to engineering design curriculum on their interest in science through a semi-structured student focus group method. This study is a part of a National Science Foundation-funded project that investigates the implementation of [de-identified program], a yearlong high school course that introduces students across the United States to engineering design principles. The Fall 2020 student focus group protocol built on the [de-identified program] 2019-2020 protocol with the addition of a science interest item to the existing engineering self-efficacy and interest items. Approximately thirty-minute semi-structured student focus groups were conducted and recorded via Zoom, then the transcripts and notes were analyzed using an in-vivo coding method. Our preliminary findings suggest that future studies should aim to gain a deeper understanding of the influence standalone engineering design courses have on students’ science interests and explore the role engineering design teachers play in increasing students’ interest in science.more » « less

K-12 engineering outreach has typically focused on elementary electrical and mechanical engineering or robot experiments integrated in science or math classes. In contrast, we propose a novel outreach program focusing on communication network principles that enable the ubiquitous web and smart-phone applications. We design outreach activities that illustrate the communication network principles through activities and team competitions in physical education (PE) as well as story writing and cartooning in English Language Arts (ELA) classes. The PE activities cover the principles of store-and-forward packet switching, Hypertext Transfer Protocol (HTTP) web page download, connection establishment in cellular wireless networks, as well as packet routing in Software-Defined Networking (SDN). The proposed outreach program has been formatively evaluated by K-12 teachers. A survey for the evaluation of the impact of the outreach program on the student perceptions, specifically, the students' interest, self-efficacy, utility, and negative stereotype perceptions towards communication network engineering, is also presented.more » « less

Community colleges play an important role in educating future scientists and engineers, especially among students from groups that are traditionally underrepresented in science, technology, engineering, and mathematics. Community college transfer programs offer lower-division courses that students can take in preparation for transfer to a four-year program. For many small community colleges, however, developing a comprehensive transfer engineering program that prepares students to be competitive for transfer can be challenging due to a lack of facilities, resources, and local expertise. As a result, engineering education becomes inaccessible to many community college students. Through a grant from the National Science Foundation Improving Undergraduate STEM Education program (NSF IUSE), three community colleges from Northern California collaborated to develop resources and teaching strategies to enable small-to-medium community college engineering programs to support a comprehensive set of lower-division engineering courses that are delivered either completely online, or with limited face-to-face interactions. This paper focuses on the development and testing of the teaching and learning resources for Engineering Graphics, which is a four-unit course (three units of lecture and one unit of lab) covering the principles of engineering drawings, computer-aided design (using both AutoCAD and SolidWorks), and the engineering design process. The paper also presents the results of the pilot implementation of the curriculum, as well as a comparison of the outcomes of the online course with those from a regular, face-to-face course. Student performance on labs and tests in the two parallel sections of the course are compared. Additionally student surveys and interviews, conducted in both the online and face-to-face course are used to document and compare students’ perceptions of their learning experience, the effectiveness of the course resources, their use of these resources, and their overall satisfaction with the course.more » « less

Seagroves, Scott; Barnes, Austin; Metevier, Anne; Porter, Jason; Hunter, Lisa (Ed.)We present highlights from a series of hands-on physics lab modules developed for remote teaching. The labs were composed of multiple self-guided inquiry modules. Though the labs were developed from scratch, some modules that were central to the design process were borrowed from previous PDP sessions and the guiding PDP principles of mirroring authentic Science, Technology, Engineering, and Mathematics (STEM) practices (e.g., allowing students to raise questions and take ownership of decision making). One notable aspect of this work is that by sourcing and assembling low-cost ($25 per student) lab kits that were sent to each student, the majority of the modules were hands-on despite being fully online. Combining online resources and simulation tools with individual hardware kits and small lab groups allowed for a mix of synchronous and asynchronous exploration. This mixed lab mode was successful in promoting both inquiry exploration and community building. One example of a lab design choice aimed at overcoming online barriers was that in lieu of weekly lab write-ups, groups submitted video checkouts in which students were encouraged to reflect on the lab, self-assess their learning outcomes, and highlight unique aspects of their lab experience. This lab was specifically developed in response to the unforeseen challenges of online teaching; however, multiple aspects of the course will seamlessly transfer to an in-person lab setting.more » « less
