   Workplace engineering problems are different from the problems that undergraduate engineering students typically encounter in most classroom settings. Students are most commonly given well-structured problems which have clear solution paths along with well-defined constraints and goals. This paper reports on research that examines how undergraduate engineering students perceived solving an ill-structured problem. Eighteen undergraduate civil engineering students were asked to solve an ill-structured engineering problem, and were interviewed after they completed solving the problem. This qualitative study is guided by the following research question: What factors do students perceive to influence their solving of an ill-structured civil engineering problem? Students’ responses to seven follow-up interview questions were transcribed and reviewed by research team members, which were used to develop codes and themes associated with these responses. Students’ transcripts were then coded following the developed codes. The analysis of data revealed that students were generally aware of the main positives and negatives of their proposed solutions to the ill-structured problem and reported that their creativity influenced their solutions and problem solving processes. Student responses also indicated that specific life events such as classes that they had taken, personal experiences, and exposure to other ill-structured problems during an internship helped them develop their proposed solution. Given students’ responses and overall findings, this supports creating learning environments for engineering students where they can support increasing their creativity and be more exposed to complex engineering problems.

2. Work-in-Progress: Seizing failure as an opportunity to learn: Undergraduate engineering students’ conceptions of failure and iteration

   Atwood, Sara A; Scalaro, Kelsey; Holcombe, Rebecca (June 2024, American Society of Engineering Education Annual Conference)

   The purpose of this work-in-progress research paper is to explore how mid-program engineering students perceive mastery-based assessment in a multidisciplinary, project-based engineering program. There have been calls in engineering education to support students beyond learning specific competencies but to also include curricular practices that help students see themselves as people who can do engineering. While it is understood that students’ mindsets and feelings of control over their own actions and outcomes are influential in how students see themselves as engineers, less is known about what specific classroom practices have this effect. Specifically, students experience assessment in relation to their learning throughout their engineering programs, but little is known about how their perceptions of these experiences impact their sense of agency or control over how and what they learn. This work explores how mastery-based learning and its associated assessment can be paired with a multidisciplinary project-based learning approach to influence students’ feelings of control and choice in their own engineering education. This paper focuses on qualitative findings from an initial pilot study for a larger, NSF-funded project at a small, Eastern private college. This exploratory pilot study includes the perceptions of four second-year engineering students enrolled in an undergraduate engineering program designed around integrated, multidisciplinary projects. A semi-structured interview with multiple open-ended questions was used to prompt participants to share their experiences with assessment in relation to their own learning, performance, confidence, and choices. Directed content and thematic analysis were used to identify codes and develop themes in relation to how participants described certain features of assessment in their engineering program. Preliminary results will illustrate students’ beliefs, learning, and perceptions of choice in relation to specific features of mastery-based assessment in a multidisciplinary project-based context. The initial themes and patterns identified in this preliminary pilot study will be used to set up a more focused secondary full data collection phase in the larger study and to initiate important conversation around the impacts of specific pedagogical choices on outcomes parallel to learning. By better understanding students’ perceptions of this pedagogical design, future classroom practices can be designed and oriented to support students in feeling agentic in their own engineering education and in becoming their version of an engineer.

3. A Plant Simulation Tool for Collaborative Biology Experiments in Middle-school Classrooms: An In-the-wild Study

   Sultana, A; Zeng, L; Wang, M; Cernova, S; Cang, X; Gnesdilow, D; Bakogeorge, A; Tibu, T; Tarun, A P; Puntambekar, S; et al (June 2024, Graphics Interface)

   Computer-aided simulation-based platforms have been shown to be effective tools for teaching STEM concepts. At the same time, Computer Supported Collaborative Learning (CSCL) platforms encourage different viewpoints and approaches from the learners which can enrich the learning experience in STEM classrooms. The deployment in recent years of networked personal devices such as Chromebooks in classrooms has motivated educators to design collaborative learning tools for these devices. However, prior work has shown that using one-on-one devices may discourage students from talking among each other, which hinders collaboration. To understand the affordances of personal devices for CSCL tools within Biology curricula, we designed a collaborative plant growth simulation application that provides mirrored plant growth simulation views for every group member to facilitate a common visualization. In this paper, we present our findings from an in-the-wild study that evaluated the affordance and usability of the plant growth simulation application and investigated the nature of collaboration and engagement aided through the simulation mirroring feature. Our study results showed that the plant simulation application had high usability and acceptance. Moreover, mirroring the plant growth simulation improved collaboration, generated excitement, and stimulated conversation. We also identified episodes where collaboration was hindered due to off-task activities, troubleshooting, group dynamics, and lack of understanding that led us to outline some potential guidelines to improve the collaborative learning experience for the students in Biology classroom.

4. Exploring perspectives and experiences of diverse learners' acceptance of online educational engineering games as learning tools in the classroom

   Cook-Chennault, Kimberly; Villanueva, Idalis (January 2020, Conference proceedings Frontiers in Education Conference)

   This Research Full paper focuses on perceptions and experiences of freshman and sophomore engineering students when playing an online serious engineering game that was designed to improve engineering intuition and knowledge of statics. Use of serious educational engineering games has increased in engineering education to help students increase technical competencies in engineering disciplines. However, few have investigated how these engineering games are experienced by the students; how games influence students' perceptions of learning, or how these factors may lead to inequitable perspectives among diverse populations of students. Purpose/Hypothesis: The purpose of this study was to explore the perceptions, appeal, and opinions about the efficacy of educational online games among a diverse population of students in an engineering mechanics statics course. It was hypothesized that compared to majority groups (e.g., men, White), women of color who are engineering students would experience less connections to the online educational game in terms of ease of use and level of frustration while playing. It is believed that these discordant views may negatively influence the game's appeal and efficacy towards learning engineering in this population of students. Design/Method: The Technology Acceptance Model (TAM) is expanded in this study, where the perspectives of women of colour (Latinx, Asian and African American) engineering students are explored. The research approach employed in this study is a mixed-method sequential exploratory design, where students first played the online engineering educational game, then completed a questionnaire, followed by participation in a focus group. Responses were initially analyzed through open and magnitude coding approaches to understand whether students thought these educational games reflected their personal culture. Results: Preliminary results indicate that though the majority of the students were receptive to using the online engineering software for their engineering education, merely a few intimated that they would use this software for engineering exam or technical job interview preparation. A level-one categorical analysis identified a few themes that comprised unintended preservation of inequality in favor of students who enjoyed contest-based education and game technology. Competition-based valuation of presumed mastery of course content fostered anxiety and intimidation among students, which caused some to "game the game" instead of studying the material, to meet grade goals. Some students indicated that they spent more time (than necessary) to learn the goals of the game than engineering content itself, suggesting a need to better integrate course material while minimizing cognitive effort in learning to navigate the game. Conclusions: Preliminary results indicate that engineering software's design and the way is coupled with course grading and assessment of learning outcomes, affect student perceptions of the technology's acceptance, usefulness, and ease of use as a "learning tool." Students were found to have different expectations of serious games juxtaposed software/apps designed for entertainment. Conclusions also indicate that acceptance of inquiry-based educational games in a classroom among diverse populations of students should clearly articulate and connect the game goals/objectives with class curriculum content. Findings also indicate that a multifaceted schema of tools, such as feedback on game challenges, and explanations for predictions of the game should be included in game/app designs.

5. Initial Findings of Engineering Faculties’ Perceptions of Mastery Assessment in a Project-based Engineering Program

   Atwood, Sara A; Scalaro, Kelsey; Holcombe, Rebecca (June 2024, American Society for Engineering Education Annual Conference)

   The purpose of this NSF grantees poster is to disseminate initial findings on faculty perception of mastery-based assessment in a project-based engineering program as part of an NSF Broadening Participation award. It is understood that pedagogical approaches influence more than what students learn but also impact their mindsets, motivation, and how they see themselves as engineers. Mastery-based teaching has seen growing popularity in engineering education as faculty strive to support students in achieving learning outcomes linked with continuous improvement to promote performance and persistence. However, this teaching approach has specific challenges as it requires significant restructuring of assessment practices including assignments, exams, evaluation processes, and grading. This work seeks to better understand faculty perspectives of assessment within mastery-based teaching to support a user-oriented perspective that can help other engineering faculty navigate the challenges of using evidence-based teaching practices in their own classrooms. This paper focuses on qualitative findings from an initial pilot study from a larger, NSF-funded Broadening Participation project at a small, Eastern private college. This exploratory pilot study includes the perceptions of two engineering faculty members using mastery teaching and assessment in a project-based engineering program. A semi-structured interview with multiple open-ended questions was used to prompt participants to share their experiences with assessment in relation to their self-efficacy around teaching and their perceptions of assessment in relation to their students’ learning, confidence, and agency. Directed content and thematic analysis were used to identify codes and develop themes in relation to how participants described certain features of assessment in their engineering program. Preliminary results will illustrate features of mastery assessment that faculty highlighted as particularly challenging or successful and related lessons learned. The initial themes and patterns identified in this preliminary pilot study will be used to set up a more focused secondary full data collection phase in the larger study. Additionally, this poster serves as an opportunity to initiate important dialogue around the implementation of mastery-based assessment and project-based learning in engineering programs and to better support engineering faculty in incorporating elements of mastery-based teaching and assessment.
