This paper reports on the development of a second-year design course intended to support student design capabilities in a coherent four-year design thread across an Electrical and Computer Engineering (ECE) curriculum. At Bucknell University students take four years of design starting by building an Internet of Things (IoT) sensor module in first year, a robust IoT product in the second year, using the product to address societal challenges in the third year, followed by a culminating capstone experience in the fourth year. While the first year introduces students broadly to the ECE curriculum, the second-year course reported here is designed to provide students’ abilities in electronic device fabrication and test and measurement, areas students at Bucknell have had little previous exposure to. This course is designed to anchor the remainder of the design sequence by giving all students the capability to independently fabricate and test robust electronic devices.
The second-year course has students individually build an IoT appliance—the Digital / Analog Modular Neopixel-based Electronic Display, or DAMNED project—by going through twelve sequential steps of design from simulation through PCB layout, device and enclosure fabrication, to application development. Because this course is most students’ first encounter with electronic fabrication and test and measurement techniques, the course has students build the project in twelve steps. Each weekly step is heavily scaffolded to allow students to work independently out of class. The paper discusses how such scaffolding is supported through design representations such as block diagrams, pre-class preparation, rapid feedback, and the use of campus makerspaces and educational software tools. The paper also shares results of making iterative improvement to the course structure using action research, and early indications that students are able transfer skills into subsequent design courses.

Adding a “Design Thread” to Electrical and Computer Engineering Degree Programs: Motivation, Implementation, and Evaluation
This article details the multi-year process of adding a “design thread” to our department’s electrical and computer engineering curricula. We use the conception of a “thread” to mean a sequence of courses that extend unbroken across each year of the undergraduate curriculum. The design thread includes a project-based introduction to the discipline course in the first year, a course in the second year focusing on measurement and fabrication, a course in the third year to frame technical problems in societal challenges, and culminates with our two-semester, client-driven fourth-year capstone design sequence. The impetus to create a design thread arose from preparation for an ABET visit where we identified a need for more “systems thinking” within the curriculum, particularly system decomposition and modularity; difficulty in having students make engineering evaluations of systems based on data; and students’ difficulty transferring skills in testing, measurement, and evaluation from in-class lab scenarios to more independent work on projects. We also noted that when working in teams, students operated more collectively than collaboratively. In other words, rather than using task division and specialization to carry out larger projects, students addressed all problems collectively as a group. This paper discusses the process through which faculty developed a shared conception of design to enable coherent changes to courses in the four year sequence and the political and practical compromises needed to create the design thread. To develop a shared conception of design faculty explored several frameworks that emphasized multiple aspects of design. Course changes based on elements of these frameworks included introducing design representations such as block diagrams to promote systems thinking in the first year and consistently utilizing representations throughout the remainder of the four year sequence. Emphasizing modularity through representations also enabled introducing aspects of collaborative teamwork. While students are introduced broadly to elements of the design framework in their first year, later years emphasize particular aspects. The second year course focuses on skills in fabrication and performance measurement while the third year course emphasizes problem context and users, in an iterative design process. The client-based senior capstone experience integrates all seven aspects of our framework. On the political and organizational side implementing the design thread required major content changes in the department’s introductory course, and freeing up six credit-hour equivalents, one and a half courses, in the curriculum. The paper discusses how the ABET process enabled these discussions to occur, other curricular changes needed to enable the design thread to be implemented, and methods which enabled the two degree programs to align faculty motivation, distribute the workload, and understand the impact the curricular changes had on student learning.

As part of a National Science Foundation-funded initiative to completely transform the civil engineering undergraduate program at Clemson University, a capstone-like course sequence is being incorporated into the curriculum during the sophomore year. Clemson’s NSF Revolutionizing Engineering Departments (RED) program is called the Arch Initiative. Just as springers serve as the foundation stones of an arch, the new courses are called “Springers” because they serve as the foundations of the transformed curriculum. Through a project-based learning approach, Springer courses mimic the senior capstone experience by immersing students in a semester-long practical application of civil engineering, exposing them to concepts and tools in a way that challenges students to develop new knowledge that they will build on and use during their junior and senior years. In the 2019 spring semester, a pilot of the first Springer course introduced students to three civil engineering sub-disciplines: construction management, water resources, and transportation. The remaining sub-disciplines are covered in a follow-on Springer 2 pilot. The purpose of this paper is to describe all aspects of the Springer 1 course, including course content, teaching methods, faculty resources, and the design and results of a Student Assessment of Learning Gains (SALG) survey to assess students’ learning outcomes. The feedback from the SALG indicated positive attitudes towards course activities and content. Challenges for full-scale implementation of the Springer course sequence as a requirement in the transformed curriculum are also discussed.more » « less

null (Ed.)Many university engineering programs require their students to complete a senior capstone experience to equip them with the knowledge and skills they need to succeed after graduation. Such capstone experiences typically integrate knowledge and skills learned cumulatively in the degree program, often engaging students in projects outside of the classroom. As part of an initiative to completely transform the civil engineering undergraduate program at Clemson University, a capstone-like course sequence is being incorporated into the curriculum during the sophomore year. Funded by a grant from the National Science Foundation’s Revolutionizing Engineering Departments (RED) program, this departmental transformation (referred to as the Arch initiative) is aiming to develop a culture of adaptation and a curriculum support for inclusive excellence and innovation to address the complex challenges faced by our society. Just as springers serve as the foundation stones of an arch, the new courses are called “Springers” because they serve as the foundations of the transformed curriculum. The goal of the Springer course sequence is to expose students to the “big picture” of civil engineering while developing student skills in professionalism, communication, and teamwork through real-world projects and hands-on activities. The expectation is that the Springer course sequence will allow faculty to better engage students at the beginning of their studies and help them understand how future courses contribute to the overall learning outcomes of a degree in civil engineering. The Springer course sequence is team-taught by faculty from both civil engineering and communication, and exposes students to all of the civil engineering subdisciplines. Through a project-based learning approach, Springer courses mimic capstone in that students work on a practical application of civil engineering concepts throughout the semester in a way that challenges students to incorporate tools that they will build on and use during their junior and senior years. In the 2019 spring semester, a pilot of the first of the Springer courses (Springer 1; n=11) introduced students to three civil engineering subdisciplines: construction management, hydrology, and transportation. The remaining subdisciplines will be covered in a follow-on Springer 2 pilot.. The project for Springer 1 involved designing a small parking lot for a church located adjacent to campus. Following initial instruction in civil engineering topics related to the project, students worked in teams to develop conceptual project designs. A design charrette allowed students to interact with different stakeholders to assess their conceptual designs and incorporate stakeholder input into their final designs. The purpose of this paper is to describe all aspects of the Springer 1 course, including course content, teaching methods, faculty resources, and the design and results of a Student Assessment of Learning Gains (SALG) survey to assess students’ learning outcomes. An overview of the Springer 2 course is also provided. The feedback from the SALG indicated positive attitudes towards course activities and content, and that students found interaction with project stakeholders during the design charrette especially beneficial. Challenges for full scale implementation of the Springer course sequence as a requirement in the transformed curriculum are also discussed.more » « less

Computer science (CS) and information technology (IT) curricula are grounded in theoretical and technical skills. Topics like equity and inclusive design are rarely found in mainstream student studies. This results in graduates with outdated practices and limitations in software development. A research project was conducted to educate the faculty to integrate inclusive software design into the CS undergraduate curriculum. The objective is to produce graduates with the ability to develop inclusive software. This experience report presents the results of teaching inclusive design throughout the four-year CS and IT curriculum, focusing on the impact on faculty. This easy-to-adopt, high-impact approach improved student retention and classroom climate, broadening participation. Research questions address faculty understanding of inclusive software design, the approach's feasibility, improvement in students’ ability to design equitable software, and assessment of the inclusiveness culture for students in computing programs. Faculty attended a summer workshop to learn about inclusive design and update their teaching materials to include the GenderMag method. Beginning in CS0 and CS1 and continuing through Senior Capstone, faculty used updated course assignments to include inclusive design in 10 courses for 44 sections taught. Faculty outcomes are positive, with the planning to include inclusive design and working with other department faculty most engaging. Faculty were impressed by student ownership and adoption of inclusive design methods, particularly in the culminating capstone senior project.more » « less

Over the last several years the Electrical and Computer Engineering (ECE) program at Bucknell University has established a four-year ‘design thread’ in the curriculum. This six-course sequence utilizes a representational approach, having students frame design challenges through diagrams and drawings before starting to implement solutions. The representations students create provide eight lenses on the design process; several of these lenses capture elements of societal implications and social justice. Within the design course sequence, the third-year particularly emphasizes the larger societal and human contexts of design. A challenge in the third-year course has been having engineering students who are acculturated to quantitative and linear methods of problem solving shift their perspectives to address complex societal topics. In the social sciences such topics are usually described textually with rich qualitative descriptions. In an attempt to engage engineering students, the authors have utilized graphical design representations rather than textual descriptions into the course. Such representations better align with engineering epistemology, potentially making the large body of work in the social sciences more accessible to students. This paper reports on how a particular representation, the system map, has third-year students explore systemic structures and practices that impact design decisions and processes. Students use system maps to identify ways design projects can impact on society in ways that have both positive and potentially negative consequences. Qualitative analysis of student artifacts over five course iterations was used in an action research approach to refine how to effectively integrate system map representations that capture societal issues and address issues of justice. Action research is an iterative methodology that utilizes evidence to improve practice, in this case the improving students’ facility with, and conceptions of, the societal impact of engineering work. This practice-focused paper reports on how system maps can be used in engineering and what supporting practices, e.g. interviews and research, make their use more effective. Ways to utilize system maps specifically, and representations more generally, to connect technical aspects of engineering design to social justice topics and issues aremore » « less
