This qualitative research study explored levels of social presence in Second Life (virtual world) associated with phases of knowledge construction. The study explored images and data collected from users at two discussion-based activities. The findings revealed the three levels of social presence, according to the Interactional Process Model of…

Augmented reality (AR) is an emergent technology beginning to be integrated into many disciplines such as engineering, architecture, and medical fields for educational purposes. The present study builds on a pilot study conducted in the spring of 2022 exploring how AR can be employed in Environmental Education (EE) by providing just-in-time…

As more and more students seek out online educational opportunities, emerging technology and platforms must provide the most effective experience for learners to expand their knowledge and skill sets. The research study aimed to investigate social presence, collaboration, and design opportunities in head-mounted, virtual reality as compared to the…

This dissertation examines the affective qualities of non-player character motion in a Virtual Reality (VR) cognitive training game, their impact on players' core affective experiences, game performance, and cognitive training outcomes. How do the movements of game characters in a VR environment affect players' experienced emotions, gameplay…

The use of Virtual Reality (VR) as an educational tool is gaining attention due to its potential to provide immersive and authentic learning experiences. However, most schools cannot afford to provide individual access to VR, making VR-mediated group learning a promising solution for those with limited access to educational resources. Despite its…

This dissertation investigates the extent to which a media audience's degree of technology acceptance (as a mediator) and interactivity of the media influence the user's sense of presence, enjoyment, and message engagement, and finally lead to attitude change (persuasion). The study also explores how the user processes a message and changes the…

Online learning has grown rapidly over the past decade in higher education. In 2019, 2.8 million higher education students were learning online, a 129.1% growth from 2018 (Straut & Boeke, 2020). Technology allows students from all over the world to learn, which has aided in the enrollment growth of online learning. Technological innovations…

The purpose of this study was to examine the effect of a treatment package consisting of video and reflection, video feedback, and coaching on pre-service teachers' use of nonverbal immediacy behaviors as they delivered lessons to student avatars in mixed reality simulations. Pre-service teachers delivered lessons at three points of time over the…

We developed an introductory chemical engineering design laboratory course coupling traditional, hands-on, and virtual learning techniques. The course is centered on a set of interactive, online simulations mimicking laboratory experimentation, which the students complete for homework prior to completing a corresponding hands-on experiment as a…

The COVID-19 pandemic of 2020 and the subsequent shutdown of all of the schools in the United States thrust teachers into distance learning environments with little or no preparation. This mixed methods exploratory study of teachers' perceptions of the role of professional learning in reducing transactional distance in a virtual environment…

Skills associated with collaborative problem solving (CPS), especially in STEM-related disciplines, are increasingly regarded as essential for success in work and life. In the last decade, simulation-based games have emerged as rich environments for the situated learning of such skills, and are instrumental in the study of CPS because they provide…

Immersive virtual worlds provide a new way to deliver online courses or parts of online and face-to-face courses. There is a growing body of research on online learning, and the data on virtual worlds is also increasing. However, literature concerning professors' experiences with specific aspects of virtual worlds is limited. For example,…

Embodied conversational agents (ECAs) have been used as virtual conversational partners in interpersonal skills training applications such as medical interviews, military decision making, and cultural training. Ideally, in interpersonal skills training users will perceive and treat the ECAs the same as they would real people. The perception and…

In order for simulations and games to be effective for learning, instructional designers must verify that the underlying computational models being used have an appropriate degree of fidelity to the conceptual models of their real-world counterparts. A simulation/game that provides incorrect feedback is likely to promote misunderstanding and…

Color is a complex and rich perceptual phenomenon that relates physical properties of light to certain perceptual qualia associated with vision. Hering's opponent color theory, widely regarded as capturing the most fundamental aspects of color phenomenology, suggests that certain unique hues are mutually exclusive as components of a single color.…
