The deployment of immersive, non-restrictive environments for instruction and learning presents a new set of challenges for instructional designers and educators. Adopting the conceptual frameworks of Sherin's (2002) learning while teaching and Vygotsky's (1978) cultural development via the mediation of tools, this paper explores one professor's pedagogical approaches used for instructing fluid dynamics concepts within the Metaverse, a highly innovative, physically immersive visualization display that does not require the use of headmounted or other restrictive devices.
