Web Services based e-learning architecture is proposed, in which various types of functionally distributed servers communicate each other and share learning-related information. These servers are assigned functions of archiving information directory, learning contents, learner information, and learning sequence of contents. On this architecture, the authors designed a function to modify sequence of learning materials automatically due to learner?s learning style. This function provides learner-adapted contents, which is incapable of conventional e-learning architecture.
