There is growing evidence of the effectiveness of project-based learning (PBL) in preparing students to solve complex problems. In PBL implementations in engineering, students are treated as professional engineers facing projects centered around real-world problems, including the complexity and uncertainty that influence such problems. Not only does this help students to analyze and solve an authentic real-world task, promoting critical thinking, but also students learn from each other, learning valuable communication and teamwork skills. Faculty play an important part by assuming non-conventional roles (e.g., client, senior professional engineer, consultant) to help students throughout this instructional and learning approach. Typically in PBLs, students work on projects over extended periods of time that culminate in realistic products or presentations. In order to be successful, students need to learn how to frame a problem, identify stakeholders and their requirements, design and select concepts, test them, and so on. 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. With the PBL implementations, it is expected that students: 1) engage in a deeper learning process where concepts can be reemphasized, and students can realize applicability; 2) develop and practice teamwork skills; 3) learn and practice how to communicate effectively to peers and to those from other fields; and 4) increase their confidence working on open-ended situations and problems. 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. Students' experiences are also presented. 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 in order 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 no major differences were observed in terms of the learned fluid mechanics content, however, the data showed interesting preliminary observations regarding teamwork satisfaction. Through reflective assignments (e.g., short answer reflections, focus groups), student perceptions of the PBL implementations are discussed in the paper. Finally, some of the challenges and lessons learned from implementing both projects multiple times, as well as access to some of the PBL course materials and assignments will be provided.

A Pilot Program in Open-Ended Problem Solving and Project Management
This research is motivated by the need for students’ early exposure to work readiness skills that promote effectiveness in dealing with complex open-ended technical problems as may be encountered in senior capstone projects or professional practice. This paper presents preliminary work in the use of building Rube Goldberg machines as student projects to foster some of these skills. Design of Rube Goldberg machines may be employed in a number of settings as a vehicle for teaching basic engineering skills. These designs require students to creatively consider a variety of unconventional approaches to solve simple problems. The Rube Goldberg paradigm allows students to communicate and to advance their ideas in a low-pressure environment where brainstorming is highly valued and where prior technical expertise affords no specific advantage. As such, projects based on Rube Goldberg machines are an effective way for freshmen and sophomore students, who may lack extensive technical skills, to acquire greater proficiency in some of the non-technical skills. This research gives results from a pilot study in project management using the Rube Goldberg model. The goal of this study is to determine the perceived efficacy of a proposed teaching vehicle for project management concepts that could strengthen the early stages of an existing series of Project Based Learning (PBL) oriented undergraduate engineering courses at the host institution, which currently make use of more closed-ended and single-solution design projects. In the study, a cohort of 27 engineering and engineering technology students participated in a sequence of extracurricular sessions in which they undertook progressively challenging open-ended project assignments. Each project introduced new constraints that required the students to address additional aspects of project management. Results from an end-of-year survey show that the participants had strongly positive impressions of their experiences related to these exercises. A majority of students felt that they had enhanced skills that would be valuable in professional life (96%), improved their leadership skills (92%), and had gained appreciation for the value of project planning (100%) and technical documentation (96%). It is anticipated that lessons learned from the project sequence will provide the framework for cross-disciplinary freshman and sophomore assignments in host institution’s PBL curriculum in the future.

This paper describes the structure, project initiatives, and early results of the NSF S-STEM funded SPIRIT: Scholarship Program Initiative via Recruitment, Innovation, and Transformation program at Western Carolina University (WCU). SPIRIT is a scholarship program focused on building an interdisciplinary engineering learning community involved in extensive peer and faculty mentoring, vertically-integrated Project Based Learning (PBL), and undergraduate research experiences. The program has provided twenty-six scholarships and academic resources to a diverse group of engineering and engineering technology students. Results from several project initiatives have been promising. Recruitment efforts have resulted in a demographically diverse group of participants whose retention rates within the program have held at 82%. A vibrant learning community has organically developed where participants are provided both academic and non-academic support across several majors and grade classes. Since May 2014, SPIRIT undergraduate research projects have resulted in forty-five presentations at seven different undergraduate and professional conferences. Twenty-seven PBL and five integrated open-ended design challenges have been completed, involving several corporate sponsors and encompassing a wide-range of engineering topics. Results from a ninety-question participant survey revealed several perceived program strengths and areas of possible improvement. Overall, the participants agreed or strongly agreed that the program had been a positive experience (4.0/4.0) and had helped them to prepare for a career in engineering (3.8/4.0). Undergraduate research activities conducted through the program have helped the participants to understand the steps involved in research processes (3.8/4.0), to appreciate the need for a combination of analysis and hands-on skills (4.0/4.0), and to become more resilient toward academic challenges and obstacles (3.8/4.0). The program’s learning community helped participants build relationships with other students outside of their major (3.1/4.0) as compared to normal course communities. Several participants believed that they were more comfortable with seeking advice from upper class students within the program (3.7/4.0) as compared to upper class students outside the program (2.7/4.0). Vertically-integrated PBL activities helped participants in understanding project management techniques (3.8/4.0), teaming techniques (3.7/4.0), and to assume a leadership role on projects (3.6/4.0). Indicated areas of program improvement included the desire and need for a system of peer-review for the students’ undergraduate research papers; a perceived hindrance to benefit from “journaling” about their program experiences (3.6/4.0); and a need for continued strengthening of activities associated with graduate school application processes as well as preparations for job interviews and applications. This paper presents details of the program initiatives, a compilation of survey results with necessary discussion, and areas of possible improvement going forward.more » « less

Research has shown that engineering students are graduating without all of the skills that they need to succeed in professional engineering practice. While undergraduate engineering programs emphasize technical design and analysis, they generally do not adequately teach or discuss marketability, and evidence suggests that engineering students are graduating without a sufficient grasp of the bigger picture of design. This is reinforced by the available tools for use in engineering education, which are highly focused on ensuring technical feasibility, and a corresponding lack of tools for engineers to explore other design needs. At the same time, research in engineering design has resulted in new market-driven design techniques, which provide guidance for design practitioners regarding how to develop products that are both technically sound and marketable. However, this concept of market-driven design has not yet been widely integrated into engineering curricula. By exploring how current students conceptualize design, this study seeks to contribute to a more balanced perspective on design in undergraduate engineers that accounts for both technical feasibility and market needs. In this paper, we examine third-year Engineering Management students’ mental models of design prior to and after a project-based design course that emphasizes market-driven design concepts and tools. The fundamental research questions are: (1) To what extent do undergraduate engineering students' initial conceptions of design account for the market context, such as competition and consumer considerations? (2) In what ways do these design conceptions change after introducing market-driven design techniques and tools in a design course? Using concept mapping exercises (pre- and post-course), open-ended reflection assignments, surveys, and an assessment of project performance, we reveal how students conceive of and learn about the market context as an integral part of the design process. This contributes to insights regarding how students conceptually balance the technical and non-technical elements of design, as well as evidence regarding the value of a constructivism-based educational approach to advancing student understanding of market-driven design. The results provide a foundational understanding and recommendations regarding holistic design education for engineers in order to reduce the school to work transition gap.more » « less

The academic preparation of scholars on infrastructure-related disciplines often takes place within isolated professional domains, rarely embracing an interdisciplinary approach for problem solving. The current work describes the implementation and outcomes from an undergraduate program designed to increase students’ awareness and knowledge of infrastructure vulnerabilities to students pursuing engineering and architecture degrees. The program, titled “Resilient Infrastructure and Sustainability Education -Undergraduate Program” utilizes the devastation from Hurricanes Irma and María for implementing an interdisciplinary case study methodology to understand and generate solutions to a variety of complex infrastructure challenges in a real-life setting. Project Based Learning (PBL) constitutes the theoretical model that frames this study. The sample included 23 undergraduate students, from architecture and engineering, and from three different campuses. All students completed a course sequence of 15 credits in design and construction of resilient and sustainable infrastructure. The results indicate that the program outcomes were achieved: development of interdisciplinary research skills and project design, hands-on solutions for real problems, awareness of human factors on project design, understanding of the importance and contribution of different disciplines and perspectives, and most important, developing the interest of putting into practice learned knowledge and skills in future projects. Students internalized the value of sustainability and resilience, in their coursework and future professionals, but also personally, applying these principles in their daily life. Students reported that their initial expectations about the program were either achieved or exceeded what they had foreseen. They considered a strength having three campuses and several disciplines working collaboratively.more » « less

Electrical and computer engineering technologies have evolved into dynamic, complex systems that profoundly change the world we live in. Designing these systems requires not only technical knowledge and skills but also new ways of thinking and the development of social, professional and ethical responsibility. A large electrical and computer engineering department at a Midwestern public university is transforming to a more agile, less traditional organization to better respond to student, industry and society needs. This is being done through new structures for faculty collaboration and facilitated through departmental change processes. Ironically, an impetus behind this effort was a failed attempt at department-wide curricular reform. This failure led to the recognition of the need for more systemic change, and a project emerged from over two years of efforts. The project uses a cross-functional, collaborative instructional model for course design and professional formation, called X-teams. X-teams are reshaping the core technical ECE curricula in the sophomore and junior years through pedagogical approaches that (a) promote design thinking, systems thinking, professional skills such as leadership, and inclusion; (b) contextualize course concepts; and (c) stimulate creative, socio-technical-minded development of ECE technologies. An X-team is comprised of ECE faculty members including the primary instructor, an engineering education and/or design faculty member, an industry practitioner, context experts, instructional specialists (as needed to support the process of teaching, including effective inquiry and inclusive teaching) and student teaching assistants. X-teams use an iterative design thinking process and reflection to explore pedagogical strategies. X-teams are also serving as change agents for the rest of the department through communities of practice referred to as Y-circles. Y-circles, comprised of X-team members, faculty, staff, and students, engage in a process of discovery and inquiry to bridge the engineering education research-to-practice gap. Research studies are being conducted to answer questions to understand (1) how educators involved in X-teams use design thinking to create new pedagogical solutions; (2) how the middle years affect student professional ECE identity development as design thinkers; (3) how ECE students overcome barriers, make choices, and persist along their educational and career paths; and (4) the effects of department structures, policies, and procedures on faculty attitudes, motivation and actions. This paper will present the efforts that led up to the project, including failures and opportunities. It will summarize the project, describe related work, and present early progress implementing new approaches.more » « less
