   The paper reports on the design of an augmented reality (AR) application for structural analysis education. Structural analysis is a significant course in every civil engineering program. The course focuses on load and stress distributions in buildings, bridges, and other structures. Students learn about graphical and mathematical models that embody structures as well as to utilize those models to determine the safety of a structure. An often reported obstacle is the missing link between these graphical models and a real building. Students often do not see the connection, which hinders them to utilize the models correctly. We designed an AR application that superimposes real buildings with graphical widgets of structural elements to help students establishing this link. The focus of this study is on application design, especially on the question whether students prefer an application that guides them when solving an engineering problem or whether the students prefer to explore. Students were asked to solve a problem with the application, which either instructed them step-by-step or allowed the students to use all feature on their own (exploring). The results are inconclusive, however, tend to favor the explore mode.

2. Addressing Issues of Justice in Design Through System-Map Representations

   Cheville, R Alan; Thomas, Rebecca; Thomas, Stewart (June 2024, ASEE PEER)

   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 are

3. 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.

4. Textual Ecology, Collaborative Tasks, and Genre Systems: Using PDE to Teach STEM Career Awareness/Intent

   Philip J. Piety, PhD (January 2021, Annual meeting program American Educational Research Association)

   null (Ed.)

   The paper discusses the use of Productive Disciplinary Engagement (PDE) for a curricular project that features a technology-based alternate reality game (ARG) with the objective of teaching undergraduate students about the collaborative nature of STEM careers. Much of the PDE research uses PDE as either a design-principle or as an analytics lens. This project does both. Most of this extant research focuses on spoken discourse to teach disciplinary knowledge. This project uses workplace documentary texts that are embedded within a semester-long undergraduate course designed to teach students collaboration skills using the context of natural disasters. A range of texts are used in this design from didactic to disciplinary. Students learn about professional work through educational renditions of professional cultural historical activity systems. This paper focuses on design decisions and illustrates some ways that workplace documents can be used in education.

5. Design and Implementation of Experiential Learning Modules for Reinforced Concrete

   Lovell, Matthew D.; Carroll, J. Chris; Kershaw, Kyle; Derks, Alec C. (January 2021, ASEE annual conference exposition)

   null (Ed.)

   Most undergraduate civil engineering programs include an introductory course in reinforced concrete design. The course generally includes an introduction to the fundamentals of reinforced concrete behavior, the design of simple beams and one-way slabs to resist shear and flexure, and the design of short columns. Because of the scale of typical civil engineering structures, students commonly do not get to experience large or full-scale structural behavior as a part of an undergraduate reinforced concrete course. Rather, students typically learn fundamental concepts through theoretical discussions, small demonstrations, or pictures and images. Without the interaction with full-scale structural members, students can struggle to develop a clear understanding of the fundamental behavior of these systems such as the differences in behavior of an over or under-reinforced beam. Additionally, students do not build an appreciation for the variations between as-built versus theoretical designs. Large-scale models can illustrate such behavior and enhance student understanding, but most civil engineering programs lack the physical equipment to perform testing at this scale. The authors from St. Louis University (SLU) and Rose-Hulman Institute of Technology (RHIT) have designed and implemented large-scale tests for in-class use that allow students to experience fundamental reinforced concrete behavior. Students design and test several reinforced concrete members using a modular strong-block testing system. This paper provides a detailed overview of the design, fabrication, and implementation of three large-scale experiential learning modules for an undergraduate reinforced concrete design course. The first module focuses on service load and deflections of a reinforced concrete beam. The first and second modules also focus on flexural failure modes and ductility. The third module focuses on shear design and failure modes. Each module uses a large scale reinforced concrete beam (Flexure specimens: 12 in. x 14 in. x 19 ft, Shear specimens: 12 in. x 14 in. x 10 ft.) that was tested on a modular strong-block testing system. The three modules were used throughout the reinforced concrete design course at SLU and RHIT to illustrate behavior concurrent to the presentation of various reinforced concrete design concepts.
