Virtual Environments in K-12 Learning and Discovery: A Grand Challenge in Education? L. A. Bievenue, D. H. Curtis, U. Thakkar National Center for Supercomputing Applications Virtual reality environments provide opportunities for the learner to create multi-sensory representations of mathematical or scientific phenomena [3, B]. Virtual environments are increasingly being used by scientists as visualization tools to explore new ways to interpret and interact with data [7]. Educational researchers also are now exploring applications of virtual environments in K-12 classrooms for training and learning [5, 9]. Due to the interactional and individualized nature of the environment, the learner here becomes an active participant in the discovery process. Learning by doing is facilitated by simulationbased virtual environments. NCSA has recently started to encourage reachers to go beyond seeing virtual reality as a demonstration tool to using it as a discovery tool. We are attempting to study if and how virtual reality might have a positive impact in education. How do such "immersive" environments play a role in furthering conceptual understanding in math and science? What different '~ays of knowing" (cf. [I]) are created by the learners (students and teachers) as they interact with and through this technology? What sort of
