The Knowledge Integration Environment is a project of Marcia Linn's research group in the Graduate School of Education at UC Berkeley.
The home page for the project is at: http://www.kie.berkeley.edu/. You might want to start out by looking over that home page. The assigned background reading for this software is:
Bell, P., Davis, E. A., & Linn, M. C. (1995). The Knowledge Integration Environment: Theory and Design. In Proceedings of the Computer Supported Collaborative Learning Conference (CSCL '95: Bloomington, IN) (pp. 14-21). Mahwah, NJ: Lawrence Erlbaum Associates.
I would like you to go through the Web-based demo of the Frogs Debate. You can get to it by scrolling down to the bottom of the KIE home page or going directly to: http://www.kie.berkeley.edu/KIE/web/frogs/description.html.
