   Cimino, R. ; Pascal, J. ; Chadha, A. ; Girgis, K. ; Khan, A. ; Ortiz, M. ( August 2022 , ASEE Annual Conference proceedings)

   The past twenty years have seen the blossoming of ethics education in undergraduate engineering programs, largely as a response to the large-scale and high-impact engineering disasters that have occurred since the turn of the century. The functional form of this education differs significantly among institutions, and in recent years active learning that demonstrates a strong impact on students’ retention and synthesis of new material have taken hold as the preferred educational methodology. Among active learning strategies, gamified or playful learning has grown in popularity, with substantial evidence indicating that games can increase student participation and social interaction with their classmates and with the subject matter. A key goal of engineering ethics education is for students to learn how to identify, frame, and resolve ethical dilemmas. These dilemmas occur naturally in social situations, in which an individual must reconcile opposing priorities and viewpoints. Thus, it seems natural that as a part of their ethics education, students should discuss contextualized engineering ethical situations with their peers. How these discussions play out, and the manner in which students (particularly first-year engineering students) address and resolve ethical dilemmas in a group setting is the main topic of this research paper. In this study, first-year engineering students from three universities across the northeastern USA participated in group discussions involving engineering ethical scenarios derived from the Engineering Ethics Reasoning Instrument (EERI) and Toxic Workplaces: A Cooperative Ethics Card Game (a game developed by the researchers). Questions were posed to the student groups, which center upon concepts such as integrity, conflicting obligations, and the contextual nature of ethical decision making. An a priori coding schema based on these concepts was applied to analyze the student responses, based upon earlier iterations of this procedure performed in previous years of the study. The primary results from this research will aim to provide some insight about first-year engineering students' mindsets when identifying, framing, and resolving ethical dilemmas. This information can inform ethics education design and development strategies. Furthermore, the experimental procedure is also designed to provide a curated series of ethical engineering scenarios with accompanying discussion questions that could be adopted in any first-year classroom for instructional and evaluative purposes.

   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.

   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.

4. 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.

5. Work in Progress: Interactive Introductory Online Modules on Wireless Communications and Radio-frequency Spectrum Sharing

   Dietrich, C. B. ; Polys, N. F. ; Reid, K. ; García Sheridan, J. A. ; Emenonye, D. ; Gomez, X. ; Tolley, J. ; Makin, C. ; Gaeddert, J. ( July 2021 , ASEE Annual Conference proceedings)

   1. Description of the objectives and motivation for the contribution to ECE education The demand for wireless data transmission capacity is increasing rapidly and this growth is expected to continue due to ongoing prevalence of cellular phones and new and emerging bandwidth-intensive applications that encompass high-definition video, unmanned aerial systems (UAS), intelligent transportation systems (ITS) including autonomous vehicles, and others. Meanwhile, vital military and public safety applications also depend on access to the radio frequency spectrum. To meet these demands, the US federal government is beginning to move from the proven but inefficient model of exclusive frequency assignments to a more-efficient, shared-spectrum approach in some bands of the radio frequency spectrum. A STEM workforce that understands the radio frequency spectrum and applications that use the spectrum is needed to further increase spectrum efficiency and cost-effectiveness of wireless systems over the next several decades to meet anticipated and unanticipated increases in wireless data capacity. 2. Relevant background including literature search examples if appropriate CISCO Systems’ annual survey indicates continued strong growth in demand for wireless data capacity. Meanwhile, undergraduate electrical and computer engineering courses in communication systems, electromagnetics, and networks tend to emphasize mathematical and theoretical fundamentals and higher-layer protocols, with less focus on fundamental concepts that are more specific to radio frequency wireless systems, including the physical and media access control layers of wireless communication systems and networks. An efficient way is needed to introduce basic RF system and spectrum concepts to undergraduate engineering students in courses such as those mentioned above who are unable to, or had not planned to take a full course in radio frequency / microwave engineering or wireless systems and networks. We have developed a series of interactive online modules that introduce concepts fundamental to wireless communications, the radio frequency spectrum, and spectrum sharing, and seek to present these concepts in context. The modules include interactive, JavaScript-based simulation exercises intended to reinforce the concepts that are presented in the modules through narrated slide presentations, text, and external links. Additional modules in development will introduce advanced undergraduate and graduate students and STEM professionals to configuration and programming of adaptive frequency-agile radios and spectrum management systems that can operate efficiently in congested radio frequency environments. Simulation exercises developed for the advanced modules allow both manual and automatic control of simulated radio links in timed, game-like simulations, and some exercises will enable students to select from among multiple pre-coded controller strategies and optionally edit the code before running the timed simulation. Additionally, we have developed infrastructure for running remote laboratory experiments that can also be embedded within the online modules, including a web-based user interface, an experiment management framework, and software defined radio (SDR) application software that runs in a wireless testbed initially developed for research. Although these experiments rely on limited hardware resources and introduce additional logistical considerations, they provide additional realism that may further challenge and motivate students. 3. Description of any assessment methods used to evaluate the effectiveness of the contribution, Each set of modules is preceded and followed by a survey. Each individual module is preceded by a quiz and followed by another quiz, with pre- and post-quiz questions drawn from the same pool. The pre-surveys allow students to opt in or out of having their survey and quiz results used anonymously in research. 4. Statement of results. The initial modules have been and are being used by three groups of students: (1) students in an undergraduate Introduction to Communication Systems course; (2) an interdisciplinary group of engineering students, including computer science students, who are participating in related undergraduate research project; and (3) students in a graduate-level communications course that includes both electrical and computer engineers. Analysis of results from the first group of students showed statistically significant increases from pre-quiz to post-quiz for each of four modules on fundamental wireless communication concepts. Results for the other students have not yet been analyzed, but also appear to show substantial pre-quiz to post-quiz increases in mean scores.
