The CoVis Project: Building a Large-Scale Science Education Testbed

Abstract : This paper describes the construction and research program of the Learning Through Collaborative Visualization (CoVis) Project. a testbed for exploring science education reform with telecommunications technology. The CoVis testbed is contrasted with other forms of cducational research in an "ecolo~yo f paradigms." which argues that testbeds are in fact a new setting for research with different requirements and challenges for the researcher. Two extended examples of telecommunications research are provided as examples of the kind of research that testbeds are ire11 suited to explore. The first example is the evolution of videoconferencing in the CoVis testbed. The second example is the design and development of a networked proupware application sailed the Collaboratory Notebook.
