A Mobile Agent Based Personalized E - Learning Model

Personalized support for learner becomes even more important, when e-learning takes place in open and dynamic learning and information network . This paper shows how to realize personalized learning support in distributed learning environment based on web services technologies . After establishing a model of the services agent , the paper constructs a framework model of personally E-Learning based on mobile agents and expresses its workflow and structures . The paper designs the algorithms for constructing agent federation and synthesizing web services based on Petri net . At last , the implementation method of the system is brought out. The system is evaluated by real application of instructions and the experiments show that the model is feasible and effective.
