   We present preliminary results of students’ strategies playing Vector Unknown: Echelon Seas [VUES], a 3D videogame intended to support student reasoning about vectors. Our team designed VUES by drawing on theories from Inquiry-Oriented Instruction (IOI), Game-Based Learning [GBL] and Realistic Mathematics Education [RME]. VUES builds from a prior 2D game by giving players vectors with 1, 2, or 3 components, depending on the level. We use codes from our team’s prior analysis (Mauntel et al, 2020) to analyze strategies in the 3D game. Early results show that students develop similar strategies during 3D gameplay as other students developed while playing the 2D game. However, we have also found new strategies that we did not witness with 2D gameplay, requiring us to extend our coding scheme. Further, early results emphasized the need for design changes to the 3D game to better support players’ progress.

2. Engineering Ethics Through High-Impact Collaborative/Competitive Scenarios (E-ETHICCS): Initial Results and Lessons Learned.

   Streiner, S; Burkey, D; Young, M.; Cimino, R.; Pascal, J.; Dahm, K. (August 2022, ASEE Annual Conference proceedings)

   Ethics education has been recognized as increasingly important to engineering over the past two decades, although disagreement exists concerning how ethics can and should be taught in the classroom. With active learning strategies becoming a preferred method of instruction, a collaboration of authors from four universities (University of Pittsburgh, University of Connecticut, Rowan University and New Jersey Institute of Technology) are investigating how game-based or playful learning with strongly situated components can influence first-year engineering students’ ethical knowledge, awareness, and decision making. This paper offers an overview and results of the progress to date of this three year, NSF Improving Undergraduate STEM Education (IUSE) grant that aims to (1) characterize the ethical awareness and decision making of first-year engineering students, (2) develop game-based learning interventions focused on ethical decision making, and (3) determine how (and why) game-based approaches affect students’ ethical awareness in engineering and the advantages of such approaches over non game-based approaches. Now in its second year, the authors have conducted a preliminary analysis of first-year students' ethical knowledge and organization via a concept mapping approach and have measured students' ethical reasoning using the Defining Issues Test 2 (DIT2) and Engineering Ethics Reasoning Instrument (EERI). Further, the authors have developed a suite of ethics-driven games that have been implemented across three of the universities, engaging over 400 first-year engineering students. Evaluation data has also been gathered for further game development and to assess initial student engagement and learning. Year 1 has provided insight into where first-year engineering students “are at” in terms of ethical knowledge and reasoning when they come to college, and how game-based instruction can be effective in the development of these students into moral agents who understand the consequences of their decisions. Further results from this investigation will provide the engineering education community with a set of impactful and research-based playful learning pedagogy and assessment that will help students confront social and ethical dilemmas in their professional lives.

3. A Case Study on When and How Novices Use Code Examples in Open-Ended Programming

   https://doi.org/10.1145/3587102.3588774  

   Wang, Wengran; Rao, Yudong; Kwatra, Archit; Milliken, Alexandra; Dong, Yihuan; Gomes, Neeloy; Martin, Sarah; Catété, Veronica; Isvik, Amy; Barnes, Tiffany; et al (June 2023, Proceedings of the 2023 Conference on on Innovation and Technology in Computer Science Education)

   Many students rely on examples when learning to program, but they often face barriers when incorporating these examples into their own code and learning the concepts they present. As a step towards designing effective example interfaces that can support student learning, we investigate novices' needs and strategies when using examples to write code. We conducted a study with 12 pairs of high school students working on open-ended game design projects, using a system that allows students to browse examples based on their functionality, and to view and copy the example code. We analyzed interviews, screen recordings, and log data, identifying 5 moments when novices request examples, and 4 strategies that arise when students use examples. We synthesize these findings into principles that can inform the design of future example systems to better support students.

4. How Can Game-Based Learning Affect Engineering Students’ Confidence?

   https://doi.org/10.1109/FIE56618.2022.9962463  

   Perez, Raul Frias; Chung, Sydney; Zastavker, Yevgeniya V.; Bennett, Victoria; Abdoun, Tarek; Harteveld, Casper (October 2022, 2022 Frontiers in Education (FIE) Conference)

   This Work-in-Progress Research paper focuses on digital game-based learning (DGBL), which refers to the use of a virtual environment to support students’ learning. In this exploratory study, we examine how students engage with GeoExplorer, a digital game-based learning environment that simulates Cone-Penetration Testing (CPT), an on-site test used in geotechnical engineering to investigate soil properties that students typically don’t have access to. In GeoExplorer’s CPT activity, students participate in a virtual internship in which they examine several sites with varied types of soil. This paper investigates DGBL environments by leveraging Self-Determination Theory (SDT) to ask the following research questions: (1) How do "freedom" and autonomy within GeoExplorer encourage students’ new emergent learning strategies? and (2) How do emergent learning strategies in GeoExplorer support students’ confidence as they self-guide their learning? Ten open-ended semi-structured interviews were performed with civil engineering students from three U.S.-based institutions. The data are analyzed using narrative analysis and a grounded theory approach. Our preliminary findings indicate that, while GeoExplorer is intended as a complement to in-person learning, it serves both as a complement and supplement to the online learning that helps to engage students during the pandemic. Students share that a felt sense of "freedom" within GeoExplorer encourages them to engage in different emergent learning strategies, such as repetition and trial and error. Students also describe that these emergent learning strategies promote knowledge retention and understanding, and further support their confidence in performing CPT. Our preliminary findings provide opportunities for students to practice autonomy and develop competency – two out of three basic psychological needs in SDT – in their educational processes.

5. Increasing Student Engagement, Fraction Knowledge, and STEM Interest Through Game-Based Intervention

   Hunt, J; Taub; M; Marino, M; Holman, K; Womack-Adams, K (January 2025, Journal of Special Education Technology)

   In this study, we evaluate the impact of a game-based supplemental fraction curriculum on student engagement, fraction knowledge, and STEM interest in inclusive elementary mathematics classrooms. Utilizing a robust experimental design, the research explores how a game-based interventions can augment traditional fraction instruction and promote STEM interest among students, including those with disabilities. The curriculum, grounded in Scheme Theory and Learning Trajectories, significantly improved students’ fraction understanding and STEM interest. These findings highlight the potential of integrating game-based learning into mathematics education to address foundational STEM concepts and advocate for further research to explore scalability and broader applicability. The results of the study underscore the potential of innovative educational strategies to enhance learning outcomes and fostering interest in STEM careers among diverse student populations.
