Title: Understanding the Roles of Low-fidelity Prototypes in Engineering Design Activity
Practical ingenuity is demonstrated in engineering design through many ways. Students and practitioners alike create many iterations of prototypes in solving problems and design challenges. While focus is on the end product and/or the process employed along the way, this study combines these interests to better understand the product and process through the roles of initial prototyping through the creation of such things as alpha prototypes, conceptual mock-ups, and other rapid prototypes. We explore the purposes and affordances of these low-fidelity prototypes in engineering design activity through both synthesis of different perspectives from literature to compose an integrated framework to characterize prototypes that are developed as part of ideation in designing, as well as historic and student examples and case studies. Studying prototyping (activity) and prototypes (artifacts) is a way to studying design thinking and how students and practitioners learn and apply a problem solving process to their work. Prototyping can make readily evident and explicit (through act of creating and the creations themselves) some of the thinking and insights of the engineering designer into the design problem. Initial, low-fidelity prototypes are characterized as prototypes that are not always elaborate depictions containing all the fine details of the design. In fact, more » features in a prototype do not always appear in the final design. The underpinning of this work is that prototyping, as a process, is an act of externalizing design thinking, embodying it through physical objects. While several prescriptive frameworks have been developed to describe what prototypes prototype and the role of prototype, the role of low-fidelity prototypes, specifically, lacks sufficient attention. We will present prototyping rather as an holistic mindset that can be a means to approach problem solving in a more accessible manner. It can be helpful to apply this sort of mindset approach from these initial problem understanding through functional decomposition to quickly communicate and learn by trial and building in learning loops to oneself, with an engineering design team, and to potential stakeholders outside the team. « less

  1. This is a research study that investigates the range of conceptions of prototyping in engineering design courses through exploring the conceptions and implementations from the instructors’ perspective. Prototyping is certainly an activity central to engineering design. The context of prototyping to support engineering education and practice has a range of implementations in an undergraduate engineering curriculum, from first-year engineering to capstone engineering design experiences. Understanding faculty conceptions’ of the reason, purpose, and place of prototyping can help illustrate how teaching and learning of the engineering design process is realistically implemented across a curriculum and how students are prepared for work practice. We seek to understand, and consequently improve, engineering design teaching and learning, through transformations of practice that are based on engineering education research. In this exploratory study, we interviewed three faculty members who teach engineering design in project-based learning courses across the curriculum of an undergraduate engineering program. This builds on related work done by the authors that previously investigated undergraduate engineering students’ conceptions of prototyping activities and process. With our instructor participants, a similar interview protocol was followed through semi-structured qualitative interviews. Data analysis has been undertaken through an emerging thematic analysis of these interview transcripts. Early findingsmore »characterize the focus on teaching the design process; the kind of feedback that the educators provide on students’ prototypes; students’ behavior while working on design projects; and educators’ perspectives on the design course. Understanding faculty conceptions with students’ conceptions of prototyping can shed light on the efficacy of using prototyping as an authentic experience in design teaching and learning. In project-based learning courses, particular issues of authenticity and assessment are under consideration, especially across the curriculum. More specifically, “proportions of problems” inform “problem solving” as one of the key characteristics in design thinking, teaching and learning. More attention to prototyping as part of the study of problem-solving processes can be useful to enhance understanding of the impact of instructional design. Challenges for teaching engineering design exist, and may be due to difficulties in framing design problems, recognizing what expertise students possess, and assessing their expertise to help them reach their goals, all at an appropriate place and ambiguity with student learning goals. Initial findings show that prototyping activities can help students become more reflective on their design. Scaffolded activities in prototyping can support self-regulated learning by students. The range of support and facilities, such as campus makerspaces, may also help students and instructors alike develop industry-ready engineering students.« less
  2. The research objective of this NSF-funded study is to explore and understand how open-ended, hands-on making work and activities can reflect student learning trajectories and learning gains in the product-based learning, undergraduate engineering classroom. The aim is to expand understanding of what making learning in the context of engineering design education might be and to illustrate educational pathways within the engineering education curriculum. Making is rooted in constructionism – learning by doing and constructing knowledge through that doing. Aspects of making work and activities that are unique to making that could appear in the engineering classroom or curriculum include: sharing, practical ingenuity, personal investment, playful invention, risk taking, community building and self-directed learning. The main research questions of this work is: How do engineering students learn and apply making? What are the attributes of making in the engineering classroom? Empirical evidence of what making in the engineering classroom looks like, and how it changes over time, and how students conceptualize making through making, designerly, and engineering ways of knowing-doing-acting will come from revisiting and additional qualitative analysis of student project data collected during a product-based learning course engineering design course. To best address the research question, this proposed study proposesmore »multiple qualitative methods to collect and analyze data on engineering students learning making. We aim to triangulate what students think they are learning, what they are being taught, and what students are demonstrating. This work is exploratory in nature. In our approach to understanding making outside of formal engineering education, at events like Maker Faires in the Maker Community, it does seem evident that there is a lot of overlap between a making mindset and a designerly way of knowing or engineering way of knowing. In the sphere of formal engineering education however, making is regularly viewed as lesser than engineering, engineering design without the engineering science or analysis. Making is not yet valued as part of formal engineering education efforts. If making is something that can be connected to beneficial student learning and is additive to the required technical content and provides a means for students to figure out what area of problems they want to tackle in the studies and beyond, it would make for a student-centered making revolution. This study advances the knowledge of the learning pathways of making by capturing empirical evidence of such learning trajectories. This study will advance the currently limited knowledge of learning in the making community and making in the engineering classroom. Initial findings generated during this study describe the learning trajectories of engineers learning making. By examining the engineering student making learning experience through the lens of cognitive science and illustrating empirical making learning trajectories, this work may impact the quality of engineering design teaching. By sharing learning trajectories across multiple communities, we seek to change the conversation by illuminating pathways for a wider array of student makers to become the makers and engineers of the future.« less
