This document discusses the differences between virtual reality (VR) and augmented reality (AR). It notes that VR fully immerses users in virtual worlds, while AR augments the real world by overlaying virtual objects. The document suggests this distinction gives AR an advantage over VR and smartphones/tablets. It also summarizes research on using VR in education, finding students are highly motivated to learn through experiential VR. VR allows interactive learning in contexts that are otherwise inaccessible and for creative expression.
