1. Virtual Reality Laboratory Experiences for Electricity and Magnetism Courses

   Ilie, R. ( July 2021 , 2021 ASEE Virtual Annual Conference Content Access)

   A solid understanding of electromagnetic (E&M) theory is key to the education of electrical engineering students. However, these concepts are notoriously challenging for students to learn, due to the difficulty in grasping abstract concepts such as the electric force as an invisible force that is acting at a distance, or how electromagnetic radiation is permeating and propagating in space. Building physical intuition to manipulate these abstractions requires means to visualize them in a three-dimensional space. This project involves the development of 3D visualizations of abstract E&M concepts in Virtual Reality (VR), in an immersive, exploratory, and engaging environment. VR provides the means of exploration, to construct visuals and manipulable objects to represent knowledge. This leads to a constructivist way of learning, in the sense that students are allowed to build their own knowledge from meaningful experiences. In addition, the VR labs replace the cost of hands-on labs, by recreating the experiments and experiences on Virtual Reality platforms. The development of the VR labs for E&M courses involves four distinct phases: (I) Lab Design, (II) Experience Design, (III) Software Development, and (IV) User Testing. During phase I, the learning goals and possible outcomes are clearly defined, to provide context for themore »VR laboratory experience, and to identify possible technical constraints pertaining to the specific laboratory exercise. During stage II, the environment (the world) the player (user) will experience is designed, along with the foundational elements, such as ways of navigation, key actions, and immersion elements. During stage III, the software is generated as part of the course projects for the Virtual Reality course taught in the Computer Science Department at the same university, or as part of independent research projects involving engineering students. This reflects the strong educational impact of this project, as it allows students to contribute to the educational experiences of their peers. During phase IV, the VR experiences are played by different types of audiences that fit the player type. The team collects feedback and if needed, implements changes. The pilot VR Lab, introduced as an additional instructional tool for the E&M course during the Fall 2019, engaged over 100 students in the program, where in addition to the regular lectures, students attended one hour per week in the E&M VR lab. Student competencies around conceptual understanding of electromagnetism topics are measured via formative and summative assessments. To evaluate the effectiveness of VR learning, each lab is followed by a 10-minute multiple-choice test, designed to measure conceptual understanding of the various topics, rather than the ability to simply manipulate equations. This paper discusses the implementation and the pedagogy of the Virtual Reality laboratory experiences to visualize concepts in E&M, with examples for specific labs, as well as challenges, and student feedback with the new approach. We will also discuss the integration of the 3D visualizations into lab exercises, and the design of the student assessment tools used to assess the knowledge gain when the VR technology is employed.« less
2. The Effectiveness of Synchronous vs Asynchronous Modes of Instruction in an Online Flipped Design Thinking Course

   Mohandas, L. ( July 2021 , 2021 ASEE Annual Conference & Exposition)

   Motivation: This is a complete paper. There was a sudden shift from traditional learning to online learning in Spring 2020 with the outbreak of COVID-19. Although online learning is not a new topic of discussion, universities, faculty, and students were not prepared for this sudden change in learning. According to a recent article in ‘The Chronicle of Higher Education, “even under the best of circumstances, virtual learning requires a different, carefully crafted approach to engagement”. The Design Thinking course under study is a required freshmen level course offered in a Mid-western University. The Design Thinking course is offered in a flipped format where all the content to be learned is given to students beforehand and the in-class session is used for active discussions and hands-on learning related to the content provided at the small group level. The final learning objective of the course is a group project where student groups are expected to come up with functional prototypes to solve a real-world problem following the Design Thinking process. There were eighteen sections of the Design Thinking course offered in Spring 2020, and with the outbreak of COVID-19, a few instructors decided to offer synchronous online classes (where instructors were presentmore »online during class time and provided orientation and guidance just like a normal class) and a few others decided to offer asynchronous online classes (where orientation from the instructor was delivered asynchronous and the instructor was online during officially scheduled class time but interactions were more like office hours). Students were required to be present synchronously at the team level during the class time in a synchronous online class. In an asynchronous online class, students could be synchronous at the team level to complete their assignment any time prior to the deadline such that they could work during class time but they were not required to work at that time. Through this complete paper, we are trying to understand student learning, social presence and learner satisfaction with respect to different modes of instruction in a freshmen level Design Thinking course. Background: According to literature, synchronous online learning has advantages such as interaction, a classroom environment, and better course quality whereas asynchronous online learning has advantages such as self-controlled and self-directed learning. The disadvantages of synchronous online learning include the learning process, technology issues, and distraction. Social isolation, lack of interaction, and technology issue are a few disadvantages related to asynchronous online learning. Problem Being Addressed: There is a limited literature base investigating different modes of online instruction in a Design Thinking course. Through this paper, we are trying to understand and share the effectiveness of synchronous and asynchronous modes of instruction in an online Flipped Design Thinking Course. The results of the paper could also help in this time of pandemic by shedding light on the more effective way to teach highly active group-based classrooms for better student learning, social presence, and learner satisfaction. Method/Assessment: An end of semester survey was monitored in Spring 2020 to understand student experiences in synchronous and asynchronous Design Thinking course sections. The survey was sent to 720 students enrolled in the course in Spring 2020 and 324 students responded to the survey. Learning was measured using the survey instrument developed by Walker (2003) and the social presence and learner satisfaction was measured by the survey modified by Richardson and Swan (2003). Likert scale was used to measure survey responses. Anticipated Results: Data would be analyzed and the paper would be completed by draft paper submission. As the course under study is a flipped and active course with a significant component of group work, the anticipated results after analysis could be that one mode of instruction has higher student learning, social presence, and learner satisfaction compared to the other.« less

   Many university engineering programs require their students to complete a senior capstone experience to equip them with the knowledge and skills they need to succeed after graduation. Such capstone experiences typically integrate knowledge and skills learned cumulatively in the degree program, often engaging students in projects outside of the classroom. As part of an initiative to completely transform the civil engineering undergraduate program at Clemson University, a capstone-like course sequence is being incorporated into the curriculum during the sophomore year. Funded by a grant from the National Science Foundation’s Revolutionizing Engineering Departments (RED) program, this departmental transformation (referred to as the Arch initiative) is aiming to develop a culture of adaptation and a curriculum support for inclusive excellence and innovation to address the complex challenges faced by our society. Just as springers serve as the foundation stones of an arch, the new courses are called “Springers” because they serve as the foundations of the transformed curriculum. The goal of the Springer course sequence is to expose students to the “big picture” of civil engineering while developing student skills in professionalism, communication, and teamwork through real-world projects and hands-on activities. The expectation is that the Springer course sequence will allow facultymore »to better engage students at the beginning of their studies and help them understand how future courses contribute to the overall learning outcomes of a degree in civil engineering. The Springer course sequence is team-taught by faculty from both civil engineering and communication, and exposes students to all of the civil engineering subdisciplines. Through a project-based learning approach, Springer courses mimic capstone in that students work on a practical application of civil engineering concepts throughout the semester in a way that challenges students to incorporate tools that they will build on and use during their junior and senior years. In the 2019 spring semester, a pilot of the first of the Springer courses (Springer 1; n=11) introduced students to three civil engineering subdisciplines: construction management, hydrology, and transportation. The remaining subdisciplines will be covered in a follow-on Springer 2 pilot.. The project for Springer 1 involved designing a small parking lot for a church located adjacent to campus. Following initial instruction in civil engineering topics related to the project, students worked in teams to develop conceptual project designs. A design charrette allowed students to interact with different stakeholders to assess their conceptual designs and incorporate stakeholder input into their final designs. The purpose of this paper is to describe all aspects of the Springer 1 course, including course content, teaching methods, faculty resources, and the design and results of a Student Assessment of Learning Gains (SALG) survey to assess students’ learning outcomes. An overview of the Springer 2 course is also provided. The feedback from the SALG indicated positive attitudes towards course activities and content, and that students found interaction with project stakeholders during the design charrette especially beneficial. Challenges for full scale implementation of the Springer course sequence as a requirement in the transformed curriculum are also discussed.« less
4. Scholarship Program Initiative via Recruitment, Innovation, and Transformation (SPIRIT): S-STEM Program Initiatives and Early Results

   Ferguson, C. ; Yan, Y. ; Yanik, P. ; & Kaul, S. ( June 2018 , American Society for Engineering Education)

   This paper describes the structure, project initiatives, and early results of the NSF S-STEM funded SPIRIT: Scholarship Program Initiative via Recruitment, Innovation, and Transformation program at Western Carolina University (WCU). SPIRIT is a scholarship program focused on building an interdisciplinary engineering learning community involved in extensive peer and faculty mentoring, vertically-integrated Project Based Learning (PBL), and undergraduate research experiences. The program has provided twenty-six scholarships and academic resources to a diverse group of engineering and engineering technology students. Results from several project initiatives have been promising. Recruitment efforts have resulted in a demographically diverse group of participants whose retention rates within the program have held at 82%. A vibrant learning community has organically developed where participants are provided both academic and non-academic support across several majors and grade classes. Since May 2014, SPIRIT undergraduate research projects have resulted in forty-five presentations at seven different undergraduate and professional conferences. Twenty-seven PBL and five integrated open-ended design challenges have been completed, involving several corporate sponsors and encompassing a wide-range of engineering topics. Results from a ninety-question participant survey revealed several perceived program strengths and areas of possible improvement. Overall, the participants agreed or strongly agreed that the program had been a positivemore »experience (4.0/4.0) and had helped them to prepare for a career in engineering (3.8/4.0). Undergraduate research activities conducted through the program have helped the participants to understand the steps involved in research processes (3.8/4.0), to appreciate the need for a combination of analysis and hands-on skills (4.0/4.0), and to become more resilient toward academic challenges and obstacles (3.8/4.0). The program’s learning community helped participants build relationships with other students outside of their major (3.1/4.0) as compared to normal course communities. Several participants believed that they were more comfortable with seeking advice from upper class students within the program (3.7/4.0) as compared to upper class students outside the program (2.7/4.0). Vertically-integrated PBL activities helped participants in understanding project management techniques (3.8/4.0), teaming techniques (3.7/4.0), and to assume a leadership role on projects (3.6/4.0). Indicated areas of program improvement included the desire and need for a system of peer-review for the students’ undergraduate research papers; a perceived hindrance to benefit from “journaling” about their program experiences (3.6/4.0); and a need for continued strengthening of activities associated with graduate school application processes as well as preparations for job interviews and applications. This paper presents details of the program initiatives, a compilation of survey results with necessary discussion, and areas of possible improvement going forward.« less
5. Advancing Student Success Through Integrated Sociocultural and Academic Intervention Strategies

   Sudarshan Kurwadkar, Salvador Mayoral ( June 2022 , Proceedings of the 2022 ASEE Annual Conference & Exposition)

   Promoting equitable undergraduate engineering education is an overarching concern at many minority-serving institutions (MSI). In addition, historical analysis of student performance in lower-division math and engineering courses at one of the largest MSI revealed an achievement gap in performance between the underrepresented minority students and other students. Furthermore, critical analysis of underlying factors overwhelmingly suggests that academic intervention coupled with sociocultural intervention may be a possible solution to help address this problem. Academic and sociocultural intervention strategies were designed and implemented in lower-division math courses through the National Science Foundation-funded project, “Building Capacity: Advancing Student Success in Undergraduate Engineering and Computer Science (ASSURE-US).” These strategies involved application-based math courses targeted explicitly at undergraduate engineering students. Results of academic intervention strategies in the lower-division math courses at one of the largest MSI demonstrate mixed effectiveness. The results of the academic intervention in lower-division Calculus I (N=150) show that 36% of students reported that the intervention was helpful and helped them learn math, while 38% were neutral. Overall, students reported having difficulty connecting the projects with the mathematics being taught. Similarly, only 10% of students expressed satisfaction with the redesigned intervention modules implemented in Integral Calculus II (N=90), while 52% were neutral.more »The sociocultural interventions include activities facilitated through the Student-Teacher Interaction Council. These activities include motivational speakers, exam preparation and stress-relief workshop, campus resources and college financial planning workshops, peer advising and learning communities, summer research, and faculty development and support. Results of the sociocultural intervention strategies show that 39% of students reported that the ASSURE-US project helped them identify role models in their discipline, while 34% reported that the project helped them identify and connect to a mentor. Students also reported higher awareness of campus resources, including mental health resources and academic support, with 89% and 90% of students reporting fully or partial understanding of these resources. The academic and sociocultural interventions of the ASSURE-US project were initially designed for in-person, hands-on, project-based, and student-faculty-involved activities; however, due to the COVID-19 pandemic, many of these activities were reimagined and redesigned for virtual instruction. The outcomes of this project so far were significantly impacted by the pandemic.« less
