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. 

A multidisciplinary service-learning project that involved teaching engineering to fourth and fifth graders was implemented in three sets of engineering and education classes to determine if there was an impact on engineering knowledge and teamwork skills in both the engineering and education students as well as persistence in the engineering students. Collaboration 1 paired a 100-level engineering Information Literacy class in Mechanical and Aerospace Engineering with a 300-level Educational Foundation class. Collaboration 2 combined a 300-level Electromechanical Systems class in Mechanical Engineering with a 400-level Educational Technology class. Collaboration 3 paired a 300-level Fluid Mechanics class in Mechanical Engineering Technology with a 400-level Elementary Science Methods class. Collaborations 1 and 3 interacted with fourth or fifth graders by developing and delivering lessons to the elementary students. Students in collaboration 2 worked with fifth graders in an after-school technology club. While each collaboration had its unique elements, all collaborations included the engineering design process both in classroom instruction and during the service learning project. Quantitative data were collected from both engineering and education students in a pretest/posttest design. Teamwork skills were measured in engineering students using a validated teamwork skills assessment based on peer evaluation. Each class had a comparison class taught by the same instructor that included a team project, and the same quantitative measures. Engineering students who participated in collaboration 1 were evaluated for retention, which was defined as students who were still enrolled in the college of engineering and technology two semesters after completion of the course. Engineering students also completed an evaluation of academic and professional persistence. For the engineering students, none of the assessments involving technical skills had significant differences, although the design process knowledge tests trended upward in the treatment classes. The preservice teachers in the treatment group scored significantly higher in the design process knowledge test, and preservice teachers in collaborations 1 and 3 had higher scores in the engineering knowledge test than the comparison group. Teamwork skills in the treatment group were significantly higher than in the comparison group for both engineering and education students. Thus, engineering and education students in the treatment groups saw gains in teamwork skills, while education students saw more gains in engineering knowledge. Finally, all engineering students had significantly higher professional persistence. 

This project was designed to address three major challenges faced by undergraduate engineering students (UES) and pre-service teachers (PSTs): 1) retention for UESs after the first year, and continued engagement when they reach more difficult concepts, 2) to prepare PSTs to teach engineering, which is a requirement in the Next Generation Science Standards as well as many state level standards of learning, and 3) to prepare both groups of students to communicate and collaborate in a multi-disciplinary context, which is a necessary skill in their future places of work. This project was implemented in three pairs of classes: 1) an introductory mechanical engineering class, fulfilling a general education requirement for information literacy and a foundations class in education, 2) fluid mechanics in mechanical engineering technology and a science methods class in education, and 3) mechanical engineering courses requiring programming (e.g., computational methods and robotics) with an educational technology class. All collaborations taught elementary level students (4th or 5th grade). For collaborations 1 and 2, the elementary students came to campus for a field trip where they toured engineering labs and participated in a one hour lesson taught by both the UESs and PSTs. In collaboration 3, the UESs and PSTs worked with the upper-elementary students in their school during an after school club. In collaborations 1 and 2, students were assigned to teams and worked remotely on some parts of the project. A collaboration tool, built in Google Sites and Google Drive, was used to facilitate the project completion. The collaboration tool includes a team repository for all the project documents and templates. Students in collaboration 3 worked together directly during class time on smaller assignments. In all three collaborations lesson plans were implemented using the BSCS 5E instructional model, which was aligned to the engineering design process. Instruments were developed to assess knowledge in collaborations 1 (engineering design process) and 3 (computational thinking), while in collaboration 2, knowledge was assessed with questions from the fundamentals of engineering exam and a science content assessment. Comprehensive Assessment of Team Member Effectiveness (CATME) was also used in all 3 collaborations to assess teamwork across the collaborations. Finally, each student wrote a reflection on their experiences, which was used to qualitatively assess the project impact. The results from the first full semester of implementation have led us to improvements in the implementation and instrument refinement for year 2. 

Major challenges in engineering education include retention of undergraduate engineering students (UESs) and continued engagement after the first year when concepts increase in difficulty. Additionally, employers, as well as ABET, look for students to demonstrate non-technical skills, including the ability to work successfully in groups, the ability to communicate both within and outside their discipline, and the ability to find information that will help them solve problems and contribute to lifelong learning. Teacher education is also facing challenges given the recent incorporation of engineering practices and core ideas into the Next Generation Science Standards (NGSS) and state level standards of learning. To help teachers meet these standards in their classrooms, education courses for preservice teachers (PSTs) must provide resources and opportunities to increase science and engineering knowledge, and the associated pedagogies. To address these challenges, Ed+gineering, an NSF-funded multidisciplinary collaborative service learning project, was implemented into two sets of paired-classes in engineering and education: a 100 level mechanical engineering class (n = 42) and a foundations class in education (n = 17), and a fluid mechanics class in mechanical engineering technology (n = 23) and a science methods class (n = 15). The paired classes collaborated in multidisciplinary teams of 5-8 undergraduate students to plan and teach engineering lessons to local elementary school students. Teams completed a series of previously tested, scaffolded activities to guide their collaboration. Designing and delivering lessons engaged university students in collaborative processes that promoted social learning, including researching and planning, peer mentoring, teaching and receiving feedback, and reflecting and revising their engineering lesson. The research questions examined in this pilot, mixed-methods research study include: (1) How did PSTs’ Ed+gineering experiences influence their engineering and science knowledge?; (2) How did PSTs’ and UESs’ Ed+gineering experiences influence their pedagogical understanding?; and (3) What were PSTs’ and UESs’ overall perceptions of their Ed+gineering experiences? Both quantitative (e.g., Engineering Design Process assessment, Science Content Knowledge assessment) and qualitative (student reflections) data were used to assess knowledge gains and project perceptions following the semester-long intervention. Findings suggest that the PSTs were more aware and comfortable with the engineering field following lesson development and delivery, and often better able to explain particular science/engineering concepts. Both PSTs and UESs, but especially the latter, came to realize the importance of planning and preparing lessons to be taught to an audience. UESs reported greater appreciation for the work of educators. PSTs and UESs expressed how they learned to work in groups with multidisciplinary members—this is a valuable lesson for their respective professional careers. Yearly, the Ed+gineering research team will also request and review student retention reports in their respective programs to assess project impact.
