This paper describes a distributed learning system which consists of two connected computers so that students can learn in collaboration and/or competition at different locations. Considering different numbers and roles of involved agents, we have enumerated 768 possible distributed learning models. Among them, we evaluated 3 models using a system which is a re-implementation of the well-known WEST program. The evaluation result has two significant implications: (1) such learning systems hold the promise to be a form of futuristic intelligent computer classroom and (2) competition could be a powerful motive in learning that would shed new light on the Intelligent Tutoring System research.
