1. Undergraduate Student Learning of Market-Driven Design Topics in a Third-Year Design Course

   Hoffenson, Steven ; Pitterson, Nicole ( July 2021 , 2021 ASEE Virtual Annual Conference)

   Generally, the focus of undergraduate engineering programs is on the development of technical skills and how they can be applied to design and problem solving. However, research has shown that there is also a need to expose students to business and society factors that influence design in context. This technical bias 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. One important contextual area is market systems, where design decisions are made while considering factors such as consumer choice, competitor behavior, and pricing. This study examines student learning throughout a third-year design course that emphasizes market-driven design through project-based activities and assignments, including a custom-made, interactive market simulation tool. To bridge the gap between market-driven design and engineering education research, this paper explores how students think about and internally organize design concepts before and after learning and practicing market-driven design approaches and tools in the context of an engineering design course. The central research question is: In what ways do student conceptions of product design change after introducing a market-driven design curriculum? In line with the constructivismmore »framework of learning, it is expected that student conceptions of design should evolve to include more market considerations as they learn about and apply market-driven design concepts and techniques to their term projects. Four different types of data instruments are included in the analysis: Concept maps generated by the students before and after the course, open-ended written reflection assignments at various points in the semester, surveys administered after learning the market simulation tool and at the end of the course, and final project reports in which student teams listed their top 3-5 lessons learned in the course. Using the changes between the pre- and post-course concept maps as the primary metric to represent evolving design conceptions, data from the reflections, surveys, and reports are evaluated to assess their influence on such learning. Because market-driven design is a multi-faceted topic, a market-driven design is hierarchically decomposed into specific sub-topics for these evaluations. These include profitability (which itself encompasses pricing and costs), modeling and simulation, and market research (which encompasses consumers and competition). For each topic, correlation analyses are performed and regression models are fit to assess the significance of different factors on learning. The findings provide evidence regarding the effectiveness of the course’s market-driven design curriculum and activities on influencing student conceptions of design.« less

   Hoffenson, Steven ; Pitterson, Nicole ; Driscoll, Jessica ( June 2020 , American Society of Engineering Education 2020)

   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 fundamentalmore »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.« less
3. Influences of Engineering Student Backgrounds and Experiences on Conceptions of Product Design

   In undergraduate engineering programs, recent emphasis has been placed on a more holistic, interdisciplinary approach to engineering education. Some programs now teach product design within the context of the market, extending the curriculum to topics outside of scientific labs and computational analysis. This study analyzes survey and concept map data collected from 154 students in a third-year engineering design course. The aim is to evaluate the impacts of student backgrounds and experiences on their mental models of product design. Data were gathered from surveys on student backgrounds and experiences, along with concept maps that were generated by the students on the first day of a product design class. The concept maps were analyzed in a quantitative manner for structural and thematic elements. The findings show that several background attributes influence student conceptions of product design. Academic major appeared to have the largest impact on a variety of variables. Additionally, prior work experience, enrollment in a master’s program, and the presence of an engineering role model at home all showed significant impacts on design conceptions. By analyzing and understanding unique backgrounds of students, educators can adjust their curricula to more effectively teach design concepts to students of various backgrounds andmore »experiences.

4. A Longitudinal Study of the Integration of Writing Support in a Multi-Semester Senior Capstone Course

   Pflueger, Ruth C. ; Meckley, Jonathan A. ( March 2022 , 2022 ASEE North Central Section Annual Conference)

   ABET lists the ability to communicate in writing to both technical and non-technical audiences as a required outcome for baccalaureate engineering students [1]. From emails and memos to formal reports, the ability to communicate is vital to the engineering profession. This Work in Progress paper describes research being done as part of an NSF-funded project, Writing Assignment Tutor Training in STEM (WATTS). The method is designed to improve feedback writing tutors without technical backgrounds give to engineering students on technical reports. Students in engineering programs have few opportunities to develop their writing skills. Usually, composition courses are part of the general education curriculum. Students often see these courses as unrelated to their majors and careers [2]. Ideally, writing support should be integrated throughout a program. Since WATTs capitalizes on existing resources and requires only a modest amount of faculty time, it could enable engineering programs to provide additional writing support to students in multiple courses and provide a bridge for them to see the connection between writing concepts learned in composition courses and their technical reports. WATTS was developed in a junior-level circuit analysis course, where students were completing the same lab and writing individual reports. This paper focuses onmore »a senior capstone course that utilizes concepts taught in previous courses to prepare students to complete an independent team research or design project. Projects are unique, usually based on the needs of an industrial sponsor, and are completed over three consecutive semesters. Each semester, teams write a report based on their activities during that semester, with a comprehensive report in the final semester. The multi-semester nature of the senior design project provides an opportunity for the researchers to chart longitudinal changes from the first to the students’ third semester interactions with the writing tutors, assessing the value of an integrated approach. The program’s impact on students’ attitudes toward revision and the value of tutoring, as well as the impact on tutors, are part of the assessment plan. The program hopes to change the students’ focus from simply presenting their results to communicating them. The goals of the project are to demonstrate to students that revision is essential to the writing process and that feedback can improve their written communication abilities. The expectation is that after graduation they will continue to seek critical feedback as part of their career growth. Surveys given to both students and tutors revealed that the sessions were taken seriously by the students and that meaningful collaboration was achieved between them. An evaluation of the writing in pre-tutored to final submitted report shows statistically significant improvement. Preliminary and current results will be included within the paper.

5. Low-Barrier Strategies to Increase Student-Centered Learning Low-Barrier Strategies to Increase Student-Centered Learning

   Friend, Nicole Erin Woodcock ( July 2021 , ASEE annual conference exposition proceedings)

   Evidence has shown that facilitating student-centered learning (SCL) in STEM classrooms enhances student learning and satisfaction [1]–[3]. However, despite increased support from educational and government bodies to incorporate SCL practices [1], minimal changes have been made in undergraduate STEM curriculum [4]. Faculty often teach as they were taught, relying heavily on traditional lecture-based teaching to disseminate knowledge [4]. Though some faculty express the desire to improve their teaching strategies, they feel limited by a lack of time, training, and incentives [4], [5]. To maximize student learning while minimizing instructor effort to change content, courses can be designed to incorporate simpler, less time-consuming SCL strategies that still have a positive impact on student experience. In this paper, we present one example of utilizing a variety of simple SCL strategies throughout the design and implementation of a 4-week long module. This module focused on introductory tissue engineering concepts and was designed to help students learn foundational knowledge within the field as well as develop critical technical skills. Further, the module sought to develop important professional skills such as problem-solving, teamwork, and communication. During module design and implementation, evidence-based SCL teaching strategies were applied to ensure students developed important knowledge and skills withinmore »the short timeframe. Lectures featured discussion-based active learning exercises to encourage student engagement and peer collaboration [6]–[8]. The module was designed using a situated perspective, acknowledging that knowing is inseparable from doing [9], and therefore each week, the material taught in the two lecture sessions was directly applied to that week’s lab to reinforce students’ conceptual knowledge through hands-on activities and experimental outcomes. Additionally, the majority of assignments served as formative assessments to motivate student performance while providing instructors with feedback to identify misconceptions and make real-time module improvements [10]–[12]. Students anonymously responded to pre- and post-module surveys, which focused on topics such as student motivation for enrolling in the module, module expectations, and prior experience. Students were also surveyed for student satisfaction, learning gains, and graduate student teaching team (GSTT) performance. Data suggests a high level of student satisfaction, as most students’ expectations were met, and often exceeded. Students reported developing a deeper understanding of the field of tissue engineering and learning many of the targeted basic lab skills. In addition to hands-on skills, students gained confidence to participate in research and an appreciation for interacting with and learning from peers. Finally, responses with respect to GSTT performance indicated a perceived emphasis on a learner-centered and knowledge/community-centered approaches over assessment-centeredness [13]. Overall, student feedback indicated that SCL teaching strategies can enhance student learning outcomes and experience, even over the short timeframe of this module. Student recommendations for module improvement focused primarily on modifying the lecture content and laboratory component of the module, and not on changing the teaching strategies employed. The success of this module exemplifies how instructors can implement similar strategies to increase student engagement and encourage in-depth discussions without drastically increasing instructor effort to re-format course content.
