This paper illustrates a goal oriented approach to model agent mediated e-learning system. Most of the traditional e-learning systems are not learner-centric, and they often ignore the diversity of learner population; thus very often their service is not able to directly or effectively match the learner's goal. From the learner's point of view, we propose a goal oriented approach to develop an agent-mediated e-learning system which provides leaner-centric and personalized e-learning services. In this paper, we illustrate how to use Goal Net to model the learner's goal and how to develop such a multi-agent system to provide efficient learning services.
