Currently the use of the computer is limited by the perception of it as a platform with advanced software tools to solve specific problems such as balancing a budget or computing grade point averages. While this is not a bad use of computers it does not fully employ their potential. By expanding our view of computer as tool to computer as medium that facilitates communication and sharing, we can fundamentally change the way we think and learn. This paper discusses the computer as a communication medium to support learning. Specifically, the paper illustrates the benefits of this reconceptualization in the context of having students author and play interactive simulations games and exchange them over the Internet.
