   Spatial reasoning skills contribute to performance in many STEM fields. For example, drawing sectional views of three-dimensional objects is an essential skill for engineering students. There is considerable variation in the spatial reasoning skills of prospective engineering students, putting some at risk for compromised performance in their classes. This study takes place in a first-year engineering Spatial Visualization course to integrate recent practices in engineering design education with cognitive psychology research on the nature of spatial learning. We employed three main pedagogical strategies in the course - 1) in class instruction on sketching; 2) spatial visualization training; and 3) manipulation of physical objects (CAD/3D print creations). This course endeavors to use current technology, online accessibility, and implementation of the three pedagogical strategies to bring about student growth in spatial reasoning. This study is designed to determine the effect of adding two different spatial reasoning training apps to this environment. Over 230 students (three sections) participated in our study. In two of the three sections, students received interactive spatial visualization training using either a spatial visualization mobile touchscreen app in one section or an Augmented Reality (AR) app in the other section. Research suggests that there are benefits to using the Spatial Vis Classroom mobile app for college students.The app has been shown to increase student persistence resulting in large learning gains as measured by the Purdue assessment of spatial visualization (PSVT-R), especially for students starting with poor spatial visualization skills. The Spatial Vis Classroom app can be used in the classroom or assigned as homework. The AR app is designed to help users develop their mental rotation abilities. It is designed to support a holistic understanding of 3-dimensional objects, and research has shown that, in combination with a traditional curriculum, it increases students’ abilities also measured by the PSVT-R. Of particular interest, the data suggest that the app overcomes the advantage found by males over females in a traditional class alone focused on spatial reasoning. Both of the course sections were required to use the apps for approximately the same time in class and outside of class. Students in the control section were required to do hand sketching activities in class and outside of class, with roughly the same completion time as for the sections with the apps. Students grades were not affected by using the three different approaches as grading was based on completion only. Based on current literature, we hypothesize that overall benefits (PSVT-R gains) will be comparable across the 3 treatments but there will be different effects on attitude and engagement (confidence,enjoyment, and self-efficacy). Lastly, we hypothesize that the treatments will have different effects on male/female and ethnic categories of the study participants. The final paper will include an analysis of results and a report of the findings.

2. Systematic Analysis of Graphics-Based Hardware and Software for Virtual Reality Instructional Framework

   Chandramouli, Magesh ( June 2019 , ASEE annual conference exposition proceedings)

   This paper explains the design of a prototype desktop and augmented Virtual Reality (VR) framework as a medium to deliver instructional materials to the students in an introductory computer animation course. This framework was developed as part of a Teaching Innovation Grant to propose a cost-effective and innovative instructional frameworks to engage and stimulate students. Desktop-based virtual reality presents a 3-dimensional (3D) world using the display of a standard desktop computer available in most of the PC labs on campus. This is a required course at this university that has students not only from the primary department, but from other colleges/departments as well. Desktop VR has been chosen as a medium for this study due to the ease-of-access and affordability; this framework can be visualized and accessed with the available computers in PC labs available in university campuses. The proposed research is intended to serve as a low-cost framework that can be accessed by all students. The concepts of ‘computer graphics, modeling & animation’, instead of being presented using conventional methods such as notes or power point presentations, are presented in an interactive manner on a desktop display. This framework allows the users to interact with the objects on the display not only via the standard mouse and keyboard, but also using multiple forms of HCI such as Touchscreen, Touchpad, and 3D Mouse. Hence, the modules were developed from scratch for access via regular desktop PCs. Such a framework helps effective pedagogical strategies such as active learning (AL) and project-based learning (PBL), which are especially relevant to a highly lab-oriented course such as this course titled ‘Introduction to Animation’. Finally, the framework has also been tested on a range of VR media to check its accessibility. On the whole, this proposed framework can be used to not only teach basic modeling and animation concepts such as spatial coordinates, coordinate systems, transformation, and parametric curves, but it is also used to teach basic graphics programming concepts. Hence, instead of a touchscreen, the modules have to be developed from scratch for access via regular desktop PCs. Such a framework helps effective pedagogical strategies such as active learning (AL) and project-based learning (PBL), which are especially relevant to a highly lab-oriented course such as this animation course.

3. Impact of a VR/AR Module on First-Year Students’ Understanding of Architectural Engineering: A Comparison Across Demographics

   McArthur, M ; Diefes-Dux, H ; Erdogmus, E ; Ryherd, E ; Armwood-Gordon, C ( August 2022 , 2022 ASEE Annual Conference & Exposition)

   Architectural Engineering (AE) programs typically offer programs of study in at least two subdisciplines that relate to building design and construction. AE students may struggle to select a subdiscipline due to their low exposure and engagement with topics that would inform their decision. Previous research indicates that the immersive nature of virtual and augmented reality (VR/AR) can increase students’ engagement and motivation regarding course content and discipline decisions. The purpose of this study was to investigate the impact of a pilot browser-based virtual reality intervention on first-year AE students’ understanding of the AE subdisciplines and choice for future study, with particular attention to demographic subgroup differences. This pilot was a testbed for a larger set of Virtual/Augmented-Reality-Based Discipline Exploration Rotations (VADERs), which are instructional modules that engage students in authentic AE tasks. In Fall 2020, the pilot VADER-1 module was incorporated into first-year AE courses at one R1 university and one R2 historically black university. This module encouraged students to explore AE subdisciplines through the virtual design of a clinic. Pre-post intervention surveys were used to investigate change in students’ understanding of AE and its subdisciplines. Students reported that their subdiscipline understanding increased significantly. Further, 74% of students reported an increase in their confidence in their choice, and over 30% of students changed their top subdiscipline choice. Some slight differences between demographic subgroups were found. VR/AR interventions hold promise for providing AE students with needed exposure to the practice of the discipline and its subdisciplines.

4. Educational Applications of Augmented Reality (AR) and Virtual Reality (VR) to Enforce Teaching the “National Academy of Engineering Grand Challenges for Engineering in the 21st Century

   Bhattarai, Bibhav ; Marghitu, Daniela ( July 2021 , International journal on advances in software)

   Dini, Petre (Ed.)

   The National Academy of Engineering’s “Fourteen Grand Challenges for Engineering in the Twenty-First Century” identifies challenges in science and technology that are both feasible and sustainable to help people and the planet prosper. Four of these challenges are: advance personalized learning, enhance virtual reality, make solar energy affordable and provide access to clean water. In this work, the authors discuss developing of applications using immersive technologies, such as Virtual Reality (VR) and Augmented Reality (AR) and their significance in addressing four of the challenges. The Drinking Water AR mobile application helps users easily locate drinking water sources inside Auburn University (AU) campus, thus providing easy access to clean water. The Sun Path mobile application helps users visualize Sun’s path at any given time and location. Students study Sun path in various fields but often have a hard time visualizing and conceptualizing it, therefore the application can help. Similarly, the application could possibly assist the users in efficient solar panel placement. Architects often study Sun path to evaluate solar panel placement at a particular location. An effective solar panel placement helps optimize degree of efficiency of using the solar energy. The Solar System Oculus Quest VR application enables users in viewing all eight planets and the Sun in the solar system. Planets are simulated to mimic their position, scale, and rotation relative to the Sun. Using the Oculus Quest controllers, disguised as human hands in the scene, users can teleport within the world view, and can get closer to each planet and the Sun to have a better view of the objects and the text associated with the objects. As a result, tailored learning is aided, and Virtual Reality is enhanced. In a camp held virtually, due to Covid-19, K12 students were introduced to the concept and usability of the applications. Likert scales metric was used to assess the efficacy of application usage. The data shows that participants of this camp benefited from an immersive learning experience that allowed for simulation with inclusion of VR and AR.

5. Virtual Reality: A Learning Tool for Promoting Learners’ Engagement in Engineering Technology

   Azzam, Israa ; Breidi, Farid ; Soudah, Peter. ( June 2023 , ASEE annual conference exposition)

   Engineering education aims to create a learning environment capable of developing vital engineering skill sets, preparing students to enter the workforce and succeed as future leaders. With all the rapid technological advancements, new engineering challenges continuously emerge, impeding the development of engineering skills. This insufficiency in developing the required skills resulted in high regression rates in students’ GPAs, resulting in industries reporting graduates’ unsatisfactory performance. From a pedagogical perspective, this problem is highly correlated with traditional learning methods that are inadequate for engaging students and improving their learning experience when adopted alone. Accordingly, educators have incorporated new learning methodologies to address the pre-defined problem and enhance the students’ learning experience. However, many of the currently adopted teaching methods still lack the potential to expose students to practical examples, and they are inefficient among engineering students, who tend to be active learners and prefer to use a variety of senses. To address this, our research team proposes integrating the technology of virtual reality (VR) into the laboratory work of engineering technology courses to improve the students’ learning experience and engagement. VR technology, an immersive high-tech media, was adopted to develop an interactive teaching module on hydraulic gripper designs in a VR construction-like environment. The module aims to expose engineering technology students to real-life applications by providing a more visceral experience than screen-based media through the generation of fully computer-simulated environments in which everything is digitized. This work presents the development and implementation of the VR construction lab module and the corresponding gripper designs. The virtual gripper models are developed using Oculus Virtual Reality (OVR) Metrics Tool for Unity, a Steam VR Overlay utility created to make visualizing the desktop in a VR setting simple and intuitive. The execution of the module comprises building the VR environment, designing and importing the gripper models, and creating a user-interface VR environment to visualize and interact with the model (gripper assembly/mechanism testing). Besides the visualization, manipulation, and interaction, the developed VR system allows for additional features like displaying technical information, guiding students throughout the assembly process, and other specialized options. Thus, the developed interactive VR module will serve as a perpetual mutable platform that can be readily adjusted to allow future add-ons to address future educational opportunities.
