Abstract 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 to elementary school students. 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 were collected from undergraduate engineering students assigned to groups in the comparison and treatment condition 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 (p-value = 0.004), were more satisfied (p-value = 0.05) and had more task commitment (p-value = 0.003) 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 regarding the project in all three categories, supporting results obtained quantitatively.
