The Research And Implement Of Network Teaching System Based On J2EE And Multi_Agent

This thesis has summarily analyzed the distance teaching system development background, the present situation and the future tendency. Aimed at situation of the present network teaching system, we introduce the Agent technology and construct a Multi_Agent network teaching system. We realize it under the J2EE technical support. To some extent this system realizes the individualized teaching.The thesis illustrates in detail the system's theory basis, design thought, function characteristic, software realization and so on. Furthermore, there are some new explorations and attempts in following several aspects: Under the cognitive theory instruction, we construct the cognitive student model and realize this model by step-by-step approach method. Thus promote the system individualized teaching ability; We introduce the Computer Adaptive Test technology that establish on Item Response Theory to implement exercise and test questions pick-up; Through the further research of Multi_Agent and J2EE, we put forward a new method which integrate the Multi_Agent technology to construct network teaching system under the J2EE platform.The system employs J2EE four-tier based structures that are Brower, Web Server, Application Server, and DB Server. The implementation of multi-tier structure enables the system to have distinguished quality of flexibility, currency and compatibility. Each can concentrate the specific role and the function. The system finally runs in J2EE application server----WebSphere Application Server, and provides more intellectualized, more convenient, highly effective network-learning environment for more and more learners.
