Two project-based learning approaches were implemented in a 100-level information literacy class in the Mechanical Engineering program at a mid-Atlantic university. One approach, the treatment group, partnered engineering students with education students to develop and deliver engineering lessons that guide elementary school students through the engineering design process. In the second approach, the comparison group, engineering students were partnered with their engineering classmates to work on an engineering problem using the engineering design process. The two projects were designed to have similar durations and course point values. For both projects, teams were formed, and peer evaluations were completed, using the Comprehensive Assessment of Team Member Effectiveness (CATME) survey. This study examined how the two project-based learning approaches affected students' teamwork effectiveness. Data was collected from undergraduate engineering students assigned to groups in the comparison and treatment conditions from Fall 2019 to Fall 2022. Data was collected electronically through the CATME teammate evaluations and project reflections (treatment, n = 137; comparison, n = 112). CATME uses a series of questions assessed on a 5-point Likert scale. Quantitative analysis using Analysis of Variance (ANOVA) and Covariance (ANCOVA) showed that engineering students in the treatment group expected more quality, were more satisfied, and had more task commitment than engineering students working within their discipline. However, no statistically significant differences were observed for teamwork effectiveness categories such as contribution to the team’s work, interaction with teammates, keeping the team on track, and having relevant knowledge, skills, and abilities. This result suggests that engineering students who worked in interdisciplinary teams with an authentic audience (i.e., children) perceived higher quality in their projects and had higher levels of commitment to the task than their peers in the comparison group. A thematic analysis of the written reflections was conducted to further explain the results obtained for the three categories: expecting quality, satisfaction, and task commitment. The thematic analysis revealed that the treatment, or interdisciplinary, groups exhibited considerably more positive reflections than their comparison peers regarding the project in all three categories, supporting results obtained quantitatively. 

Seventy-three students who enrolled in a senior-year level fluid mechanics course during spring semesters from 2019-2022 were asked about their perceptions on the impact in their professional preparation of a semester-long multidisciplinary service-learning assignment. This paper evaluates their current perceived impact of the assignment (long-term impact) and whether it might have changed from when they took the course (short-term impact). A survey was sent to all former students who went through the course and participated in the assignment, with a 61.64% return rate. The survey included questions about how well they remembered the assignment (some of the students were involved in it 4 years prior to completing this survey), the relevance of the project in terms of their professional preparation, how it impacted their collaboration skills, and whether their involvement affected their interest in participating in engineering outreach activities. To determine how their perceived impact of the project on their professional preparation has changed from when they took the class to now when they are working professionals, we compare their recent responses to the responses in reflections they completed while taking the course. The information gathered in the survey also provides a means to evaluate the effectiveness of the project and identify areas for improvement, which has implications for how similar projects might be designed and enacted in the future. 

Engineering is becoming increasingly cross-disciplinary, requiring students to develop skills in multiple engineering disciplines (e.g., mechanical engineering students having to learn the basics of electronics, instrumentation, and coding) and interprofessional skills to integrate perspectives from people outside their field. In the workplace, engineering teams are frequently multidisciplinary, and often, people from outside of engineering are part of the team that brings a product to market. Additionally, teams are often diverse in age, race, gender, and in other areas. Teams that creatively utilize the contrasting perspectives and ideas arising from these differences can positively affect team performance and generate solutions effective for a broader range of users. These trends suggest that engineering education can benefit from having engineering students work on team projects that involve a blend of cross-disciplinary and mixed-aged collaborations. An NSF-funded project set out to explore this idea by partnering undergraduate engineering students enrolled in a 300-level electromechanical systems course with preservice teachers enrolled in a 400-level educational technology course to plan and deliver robotics lessons to fifth graders at a local school. Working in small teams, students designed, built, and coded bio-inspired robots. The collaborative activities included: (1) training with Hummingbird Bit hardware (Birdbrain Technologies, Pittsburgh, PA) (e.g. sensors, servo motors) and coding platform, (2) preparing robotics lessons for fifth graders that explained the engineering design process, and (3) guiding the fifth graders in the design of their robots. Additionally, each engineering student designed a robot following the theme developed with their education student and fifth-grade partners. 

Preservice teachers (PSTs) in an educational foundations course were tasked with leading elementary students in an engineering design challenge. To explore different approaches for helping the PSTs develop competence in engineering education, two implementation methods were tested. In Spring 2022, PSTs collaborated with undergraduate engineering students to develop carnival-themed design challenge lessons. In Fall 2022, PSTs worked with their PST classmates to teach a professionally prepared engineering lesson focused on designing plastic filters. PSTs’ knowledge of engineering and engineering pedagogy were compared across the two semesters using an exploratory approach. Both groups showed increases in engineering knowledge and engineering pedagogical knowledge. Item-level differences suggest unique benefits to each approach providing insight for teacher educators designing interventions to prepare PSTs to integrate engineering into elementary education. 

The integration of engineering content at the pre-college level is gaining global traction as a strategy to improve learning outcomes and to promote inclusion and diversity in STEM (Science, Technology, Engineering, and Mathematics). Preservice teacher programs have become natural insertion points for integration efforts by providing future K-12 teachers with the resources and preparation to teach engineering as part of their academic preparation. There is a need to understand the socio-cognitive mechanisms by which teacher preparation programs can help teachers to integrate engineering in their future classrooms. This work examines how an innovative cross disciplinary program impacted important social-cognitive drivers of engineering integration. We used mediation analysis to understand a successful pathway to engineering integration as a result of exposure to a cross-disciplinary collaboration with engineering students. This study revealed how participation in the program as part of their academic preparation increased PTSs’ confidence to teach engineering and their beliefs about the importance of engineering content, which in turn, increased their intention to integrate engineering in the classroom. 

Though elementary educators recognize the importance of integrating engineering in their classrooms, many feel challenged and unprepared to teach engineering content. The absence of effective engineering instruction in teacher preparation programs leaves future educators unprepared for this challenge. Ed+gineering is an NSF-funded partnership between education and engineering aimed at increasing preservice teacher (PST) preparation, confidence, and intention to integrate engineering into their teaching. Ed+gineering partners education and engineering students in multidisciplinary teams within the context of their respective university courses. As part of their coursework, the teams plan and deliver culturally responsive engineering lessons to elementary school students under the guidance of one engineering and one education faculty. This paper investigates the impact of Ed+gineering on PSTs’ knowledge of engineering practices, engineering pedagogical knowledge, self-efficacy to integrate engineering, and beliefs about engineering integration. The impact of Ed+gineering on participating PSTs was assessed using three collaborations involving students in engineering and education during Fall 2019 and Spring 2020. Preliminary results suggest that the Ed+gineering partnership positively impacted engineering-pedagogical knowledge, knowledge of engineering practices, and self efficacy for integrating engineering. The specific magnitude of the impact and its implications are discussed. 

Engineers need to develop professional skills, including the ability to work successfully in teams and to communicate within and outside of their discipline, in addition to required technical skills. A collaborative multi-disciplinary service learning project referred to as Ed+gineering was implemented in a 100-level mechanical engineering course. In this collaboration, mechanical engineering students, primarily in the second semester of their freshman year or first semester of their second year, worked over the course of a semester with education students taking a foundations course to develop and deliver engineering lessons to fourth or fifth graders. Students in comparison engineering classes worked on a team project focused on experimental design for a small satellite system. The purpose of this study was to determine if participating in the Ed+gineering collaboration had a positive effect on teamwork effectiveness and satisfaction when compared to the comparison class. In both team projects, the five dimensions of the Comprehensive Assessment of Team Member Effectiveness (CATME) system were used as a quantitative assessment. The five dimensions of CATME Behaviorally Anchored Ratings Scale (BARS) (contribution to the team’s work, interacting with teammates, keeping the team on track, expecting quality, and having relevant Knowledge, Skills, and Abilities - KSAs) were measured. Additionally, within the CATME platform team satisfaction, team interdependence and team cohesiveness were measured. ANCOVA analysis was used to assess the quantitative data from CATME. Preliminary results suggest that students in the treatment classes had higher team member effectiveness and overall satisfaction scores than students in the comparison classes. Qualitative data from reflections written at the completion of the aforementioned projects were used to explore these results.
