Research on adaptive e-Learning system using technology of learning navigation

E-Learning system, as a great product of modern information technology, is an important way to implement education modernization. Many e-Learning systems have been developed in recent years. However, most of them are unable to organize and present education materials flexibly according to individual learner´s knowledge basis and learning ability. Based on detailed research of the deficiencies in current systems´ adaptability a new adaptive algorithm for adaptive e-Learning systems is designed and implemented, which is based on algorithm of the ´Bayesian Network´. This paper introduces the designs of adaptive e-Learning system´s prototype, adaptability diagnosing strategy and adaptive learning path strategy, designs of system functional models, business flow and data flow.
