Development of effective oral presentation skills is an essential component of entrepreneurship education, but class size and time constraints can limit opportunities to practice and receive quality feedback. Immersive virtual reality can provide time- and place-independent opportunities to hone presentation skills in diverse settings with…

Recent research has emphasized the importance of leveraging embodied interactions for learning critical STEM concepts. ELASTIC3S--an embodied environment for learning about cross-cutting concepts (i.e., non-linear growth)--allows learners to interact with different science simulations through whole-body gestures. Technological advances in gesture…

A challenge for the virtual reality (VR) industry is facing is that VR is not immersive enough to make people feel a genuine sense of presence: the low frame rate leads to dizziness and the lack of human body visualization limits the human-computer interaction. In this dissertation, I present our research on enhancing visual and gestural fidelity…

This study examined the differences between student's self-reported communication interview skills before and after they received interview instructions and experienced virtual simulation interviews in a basic communication course. Incorporating interview instruction and utilizing mock interviewing software, InterviewStream, into several basic…

In this study, we follow students' modeling and covariational reasoning in the context of learning about big data. A three-week unit was designed to allow 12th grade students in a mathematics course to explore big and mid-size data using concepts such as trend and scatter to describe the relationships between variables in multivariate settings.…

This paper reports on the different gesture types employed by twenty-three Year 10 students as they endeavoured to explain their understanding of rate of change associated with the functions resulting from two different computer simulations. These gestures also have application to revealing students' understanding of functions. However,…

Three-dimensional (3-D) multi-user virtual environments (3-D MUVEs) have been used to provide language learners with realistic scenarios in which verbal and non-verbal interactions are simulated. However, little is known of the underlying factors that shape interaction in avatar-based virtual worlds. This study examined the perceptions of 38…

This paper examines the effective deployment of conversational agents in virtual worlds from the perspective of researchers/practitioners in cognitive psychology, computing science, learning technologies and engineering. From a cognitive perspective, the major challenge lies in the coordination and management of the various channels of information…
