   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.

2. Work in Progress: Formation of an engineering identity in first-year students through an intervention centered on senior design projects

   Richards, Abigail M ; Anderson, Ryan ; Myers, Carrie B ( July 2020 , ASEE annual conference exposition)

   Abstract This “work in progress” paper describes a multiyear project to study the development of engineering identity in a chemical and biological engineering program at Montana State University. The project focuses on how engineering identity may be impacted by a series of interventions utilizing subject material in a senior-level capstone design course and has the senior capstone design students serve as peer-mentors to first- and second-year students. A more rapid development of an engineering identity by first- and second-year students is suspected to increase retention and persistence in this engineering program. Through a series of timed interventions scheduled to take place in the first and second year, which includes cohorts that will serve as negative controls (no intervention), we hope to ascertain the following: (1) the extent to which, relative to a control group, exposure to a peer mentor increases a students’ engineering identity development over time compared to those who do not receive peer mentoring and (2) if the quantity and/or timing of the peer interactions impact engineering identity development. While the project includes interventions for both first- and second-year students, this work in progress paper focuses on the experiences of first year freshman as a result of the interventions and their development of an engineering identity over the course of the semester. Early in the fall semester, freshman chemical engineering students enrolled in an introductory chemical engineering course and senior students in a capstone design course were administered a survey which contained a validated instrument to assess engineering identity. The first-year course has 107 students and the senior-level course has 92 students and approximately 50% of the students in both cohorts completed the survey. Mid-semester, after the first-year students were introduced to the concepts of process flow diagrams and material balances in their course, senior design student teams gave presentations about their capstone design projects in the introductory course. The presentations focused on the project goals, design process and highlighted the process flow diagrams. After the presentations, freshman and senior students attended small group dinners as part of a homework assignment wherein the senior students were directed to communicate information about their design projects as well as share their experiences in the chemical engineering program. Dinners occurred overall several days, with up to ten freshman and five seniors attending each event. Freshman students were encouraged to use this time to discover more about the major, inquire about future course work, and learn about ways to enrich their educational experience through extracurricular and co-curricular activities. Several weeks after the dinner experience, senior students returned to give additional presentations to the freshman students to focus on the environmental and societal impacts of their design projects. We report baseline engineering identity in this paper.

3. HydroLearn: Improving Students’ Conceptual Understanding and Technical Skills in a Civil Engineering Senior Design Course

   Gallagher, M. A. ( July 2021 , 2021 ASEE Virtual Annual Conference)

   Engineering graduates need a deep understanding of key concepts in addition to technical skills to be successful in the workforce. However, traditional methods of instruction (e.g., lecture) do not foster deep conceptual understanding and make it challenging for students to learn the technical skills, (e.g., professional modeling software), that they need to know. This study builds on prior work to assess engineering students’ conceptual and procedural knowledge. The results provide an insight into how the use of authentic online learning modules influence engineering students’ conceptual knowledge and procedural skills. We designed online active learning modules to support and deepen undergraduate students’ understanding of key concepts in hydrology and water resources engineering (e.g., watershed delineation, rainfall-runoff processes, design storms), as well as their technical skills (e.g., obtaining and interpreting relevant information for a watershed, proficiency using HEC-HMS and HEC-RAS modeling tools). These modules integrated instructional content, real data, and modeling resources to support students’ solving of complex, authentic problems. The purpose of our study was to examine changes in students’ self-reported understanding of concepts and skills after completing these modules. The participants in this study were 32 undergraduate students at a southern U.S. university in a civil engineering senior design course who were assigned four of these active learning modules over the course of one semester to be completed outside of class time. Participants completed the Student Assessment of Learning Gains (SALG) survey immediately before starting the first module (time 1) and after completing the last module (time 2). The SALG is a modifiable survey meant to be specific to the learning tasks that are the focus of instruction. We created versions of the SALG for each module, which asked students to self-report their understanding of concepts and ability to implement skills that are the focus of each module. We calculated learning gains by examining differences in students’ self-reported understanding of concepts and skills from time 1 to time 2. Responses were analyzed using eight paired samples t-tests (two for each module used, concepts and skills). The analyses suggested that students reported gains in both conceptual knowledge and procedural skills. The data also indicated that the students’ self-reported gain in skills was greater than their gain in concepts. This study provides support for enhancing student learning in undergraduate hydrology and water resources engineering courses by connecting conceptual knowledge and procedural skills to complex, real-world problems.

5. Adding a “Design Thread” to Electrical and Computer Engineering Degree Programs: Motivation, Implementation, and Evaluation

   Cheville, R. A. ; Thompson, M. S. ; Thomas, S. ( July 2021 , ASEE annual conference exposition)

   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.
