Two different implementations of PBL projects in a fluid mechanics course are presented in this paper. This required junior-level course has been taught since 2014 by the same instructor. The first PBL project presented is a complete design of pumped pipeline systems for a hypothetical plant. In the second project, engineering students partnered with pre-service teachers to design and teach an elementary school lesson on fluid mechanics concepts. The goal of this paper is to present the experiences of the authors with both PBL implementations. It explains how the projects were scaffolded through the entire semester, including how the sequence of course content was modified, how team dynamics were monitored, the faculty roles, and the end products and presentations. To evaluate and compare students' learning and satisfaction with the team experience between the two PBL implementations, a shortened version of the NCEES FE exam and the Comprehensive Assessment of Team Member Effectiveness (CATME) survey were utilized. Students completed the FE exam during the first week and then again during the last week of the semester to assess students' growth in fluid mechanics knowledge. The CATME survey was completed mid-semester to help faculty identify and address problems within team dynamics, and at the end of the semester to evaluate individual students' teamwork performance. The results showed that the type of PBL approach used in the course did not have an impact on fluid mechanics content knowledge; however, the data suggests that the cross-disciplinary PBL model led to higher levels of teamwork satisfaction. Through reflective assignments, student perceptions of the PBL implementations are discussed in the paper. Finally, some of the PBL course materials and assignments are provided.

This work-in-progress paper describes engineering students' experiences in an NSF-funded project that partnered undergraduate engineering students with pre-service teachers to plan and deliver robotics lessons to fifth graders at a local school. This project aims to address an apparent gap between what is taught in academia and industry's expectations of engineers to integrate perspectives from outside their field to solve modern societal problems requiring a multidisciplinary approach. Working in small teams over Zoom, participating engineering, education, and fifth grade students designed, built, and coded bio-inspired COVID companion robots. The goal for the engineering students was to build new interprofessional skills, while reinforcing technical skills. The collaborative activities included: (1) training with Hummingbird BitTM hardware (e.g. sensors, servo motors) and coding platform, (2) preparing robotics lessons for fifth graders that explained the engineering design process (EDP), and (3) guiding the fifth graders in the design of their robots. Additionally, each undergraduate engineering student designed a robot following the theme developed with their preservice teacher and fifth grade partners. The intervention took place in Spring 2021 amidst the COVID-19 pandemic, necessitating the investigators to make critical decisions to address challenges of implementing the intervention in an online setting. This paper describes those decisions as it investigates how the cross-disciplinary, mixed-aged collaboration with preservice teachers and fifth graders impacted undergraduate engineering students' learning and investment during the design process of their robots. Preliminary results of a regression analysis revealed a relationship between the engineering students' robot rankings and post-scores on the design process knowledge survey (r = 0.92). Consistencies and a few anomalies in this pattern were explained using qualitative reflections which were analyzed to determine students' level of investment in the project, overall perceptions, and the extent to which they focused on the fifth graders' ideas in their designs. In general, robot quality was linked to both undergraduate engineering students' level of investment and whether they focused on the fifth graders' ideas in their designs. Engineering students' overall perceptions of the project were generally positive, appreciating the role of cross-disciplinary and mixed-aged collaborations in their learning to brainstorm innovative solutions and interact effectively with professionals outside of engineering as they embark on tackling societal problems in the real world.

Professional engineers spend a considerable portion of their day writing, yet disciplinary writing skills are not addressed in many engineering courses. This study investigates peer review as a mean to enhance student writing in engineering courses. Students completed formative peer reviews using an online peer review system for a group project in a fluid mechanics course (with online and face-to-face sections) and for an individual writing assignment in a senior capstone class in mechanical engineering. A university-wide rubric for disciplinary writing was used to assess student writing performance on interim and final assignments completed over the course of a semester. Online surveys were used to assess student perceptions of the peer review process. The study was implemented over two semesters with iterative revisions in instruction made between semesters based on initial findings. Results suggest that peer review can increase student performance, as long as reflections are used to prompt student revision, regardless of the class delivery method or assignment type.
