| Abstract: | In this paper, we explore how the application of multimedia design principles may inform the development of educational multi-user virtual environments (MUVEs). We look at design principles that have been shown to help learners manage cognitive load within multimedia environments and conduct a conjectural analysis of the extent to which such principles can help manage cognitive load in the highly immersive “beyond multimedia” environments that 3-D educational MUVEs represent. We frame our discussion as a design practice analysis of the River City MUVE, a science inquiry environment that has middle school students collaborating to develop and test hypotheses regarding illnesses sweeping a virtual town. We analyze the current River City interface design using a framework describing cognitive overload scenarios and associated approaches to manage cognitive load. We also discuss the potential difficulties that may be seen as multimedia principles are applied to 3-D MUVEs. Our discussion describes a blueprint for research implementations that we are undertaking to systematically investigate the effect of an educational MUVE interface design based on multimedia principles—implementations that we hope will provide an action framework for other MUVE researchers to use in their own studies. |
