1. Leveraging Sustainability to Teach About Social Justice in Civil Engineering Curricula

   Siller, T. ; Atadero, R. A. ; Casper, A. M. ; Paguyo, C. H. ( June 2022 , IJEE International Journal of Engineering Education)

   Sustainability is a vital interdisciplinary concept to address within engineering education. Furthermore, the natural connections that exist between sustainability and social justice provide an optimal opportunity to integrate both into curricula. We argue that engineering curricula ought to include sustainability and social justice so future engineers are trained to understand both societal and technical implications of their work, while acknowledging the challenges engineering faculty may face in conceptualizing social justice or social sustainability. We then highlight how new sustainable design rating systems, such as Envision and The Living Building Challenge, embed inclusion and social justice into their ratings and how these sustainability rating systems can help engineering faculty bring social justice into their classrooms in ways that meaningfully link to engineering content. Finally, we present two examples of how sustainability and social justice can be incorporated into the civil engineering curriculum through inclusive pedagogy and new curricula: 1) a semester-long effort to document, design, and improve the inclusive pedagogical practices in a first-year engineering course that included the theme of sustainability throughout much of the class meetings; and 2) a new assignment about the Envision rating system and the societal implications of rebuilding a major component of regional infrastructure. We conclude with recommendations that other instructors can use to begin incorporating social justice in their courses.

   Researchers, educators, and multimedia designers need to better understand how mixing physical tangible objects with virtual experiences affects learning and science identity. In this novel study, a 3D-printed tangible that is an accurate facsimile of the sort of expensive glassware that chemists use in real laboratories is tethered to a laptop with a digitized lesson. Interactive educational content is increasingly being placed online, it is important to understand the educational boundary conditions associated with passive haptics and 3D-printed manipulables. Cost-effective printed objects would be particularly welcome in rural and low Socio-Economic (SES) classrooms. A Mixed Reality (MR) experience was created that used a physical 3D-printed haptic burette to control a computer-based chemistry titration experiment. This randomized control trial study with 136 college students had two conditions: 1) low-embodied control (using keyboard arrows), and 2) high-embodied experimental (physically turning a valve/stopcock on the 3D-printed burette). Although both groups displayed similar significant gains on the declarative knowledge test, deeper analyses revealed nuanced Aptitude by Treatment Interactions (ATIs). These interactionsfavored the high-embodied experimental group that used the MR devicefor both titration-specific posttest knowledge questions and for science efficacy and science identity. Those students with higher prior science knowledge displayed higher titration knowledge scores after using the experimental 3D-printed haptic device. A multi-modal linguistic and gesture analysis revealed that during recall the experimental participants used the stopcock-turning gesture significantly more often, and their recalls created a significantly different Epistemic Network Analysis (ENA). ENA is a type of 2D projection of the recall data, stronger connections were seen in the high embodied group mainly centering on the key hand-turning gesture. Instructors and designers should consider the multi-modal and multi-dimensional nature of the user interface, and how the addition of another sensory-based learning signal (haptics) might differentially affect lower prior knowledge students. One hypothesis is that haptically manipulating novel devices during learning may create more cognitive load. For low prior knowledge students, it may be advantageous for them to begin learning content on a more ubiquitous interface (e.g., keyboard) before moving them to more novel, multi-modal MR devices/interfaces.

3. Creating Meaningful Learning Opportunities through Incorporating Local Research into Chemistry Classroom Activities

   Incorporating real-life context through connections to research early in the curriculum can create meaningful learning opportunities that encourage students to engage deeply with classroom content to construct chemistry knowledge. Course-based undergraduate research experiences have been successful at integrating real-life context, but are often only incorporated into upper-level courses. To provide an additional pathway to foster interaction with research, four activities from an introductory chemistry discussion class were created to incorporate authentic research connections. Care was taken to incorporate metacognitive questions designed to help students make connections between their preexisting knowledge and course content. Marzano’s taxonomy was used to analyze the cognitive complexity of tasks, which increased in the revised activities, allowing for more opportunities for knowledge construction. Audio and written work of student groups as they worked through activities was collected. Qualitative analysis of student engagement revealed that control over the content of activities to incorporate opportunities for knowledge construction is not enough to facilitate students consciously engaging in meaningful learning. If instructors wish to promote students integrating chemistry knowledge into their existing framework, course instructors, including graduate teaching assistants, need to be trained on how to properly facilitate classroom experiences to increase the likelihood of success.

4. Implementing Integrated Project-Based Learning Outcomes in a 21st-Century Environmental Engineering Curriculum

   Gallagher, S. ; Phillips, A. ; Lauchnor, E. ; Hohner, A. ; Stein, O. R. ; Woolard, C. R. ; Kirkland, C. M. ; Plymesser, K ( June 2022 , 2023 ASEE annual conference exposition)

   Engineering education research and accreditation criteria have for some time emphasized that to adequately prepare engineers to meet 21st century challenges, programs need to move toward an approach that integrates professional knowledge, skills, and real-world experiences throughout the curriculum [1], [2], [3]. An integrated approach allows students to draw connections between different disciplinary content, develop professional skills through practice, and relate their emerging engineering competencies to the problems and communities they care about [4], [5]. Despite the known benefits, the challenges to implementing such major programmatic changes are myriad, including faculty’s limited expertise outside their own disciplinary area of specialization and lack of perspective of professional learning outcomes across the curriculum. In 2020, Montana State University initiated a five-year NSF-funded Revolutionizing Engineering Departments (RED) project to transform its environmental engineering program by replacing traditional topic-focused courses with a newly developed integrated and project-based curriculum (IPBC). The project engages all tenure-track faculty in the environmental engineering program as well as faculty from five external departments in a collaborative, iterative process to define what students should be expected to know and do at the completion of the undergraduate program. In the process, sustainability, professionalism, and systems thinking arose as foundational pillars of the successful environmental engineer and are proposed as three knowledge threads that can be woven throughout environmental engineering curricula. The paper explores the two-year programmatic redesign process and examines how lessons learned through the process can be applied to course development as the team transitions into the implementation phase of the project. Two new integrated project-based learning courses targeting the 1st- and 2nd-year levels will be taught in academic year 2023-2024. The approach described in this work can be utilized by similar programs as a model for bottom-up curriculum development and integration of non-technical content, which will be necessary for educating engineers of the future.

5. Institutional Change Efforts to Improve the Environment for Both Instructors and Students in Foundational Engineering Courses

   Grohs, J.R. ; Knight, D.B. ; Soledad, M.M. ; Murzi, H. ; Smith, N. ( June 2019 , ASEE Annual Conference proceedings)

   Foundational engineering courses are critical to student success in engineering programs. The conceptually challenging content of these courses establishes the requisite knowledge for future classes. Thus, it is no surprise that such courses can serve as barriers or gatekeepers to successful student progress through the undergraduate curriculum. Although the difficulty of the courses may be necessary, often other features of the course delivery such as large class environments or a few very high-stakes assessments can further exacerbate these challenges. And especially problematic, past studies have shown that grade penalties associated with these courses and environments may disproportionately impact women. On the faculty side, institutions often turn to non-tenure track instructional faculty to teach multiple sections of foundational courses each semester. Although having faculty whose sole role is dedicated to quality teaching is an asset, benefits would likely be maximized when such faculty have clear metrics for paths to promotion, some autonomy and ownership regarding the curriculum, and overall job satisfaction. However, literature suggests that faculty, like students, note ill effects from large classes, such as challenges connecting and building rapport with students and having time to offer individualized feedback to students. Our NSF IUSE project focuses on instructors of large foundational engineering students with the belief that by better understanding the educational environment from their perspective we can improve the quality of the teaching and learning environment for all engineering students. Our project regularly convenes faculty teaching an array of core courses (e.g,. Mathematics, Chemistry, Mechanics, Physics) and uses insights from these meetings and individual interviews to identify possible leverage points where our project or the institution more broadly might affect change. Parallel to this effort, we have been working with data stewards on campus to gain access to institutional data (e.g., student course and grade histories, student evaluations of faculty teaching) to link and provide aggregate deidentified results to faculty to feed more information in to their decision-making. We are demonstrating that regular engagement between faculty and institutional leaders around analyzed and curated data is essential to continuous and systematic improvement. Efforts to date have included building an institutional data explorer dashboard (e.g., influences of pre-requisite courses on future courses) and drafting reports to be sent to department heads and associate deans which gather priorities identified in the first year of our research. For example, participating instructors identified that clarity of promotion paths across non-tenure track teaching faculty from different departments varied greatly, and the institution as a whole could benefit from clarified university-wide guidance. While some findings may be institution-specific (NSF IUSE Institutional Transformation track), as a large public research institution, peer-institutions with high engineering enrollments often face similar challenges and so findings from our change efforts potentially have broad applicability.
