Studying And Design For Distance Learning System Based On Agent Technology

The development of network technology provides a new field for distance education. The system of distance instruction is a sort of web-based distance education. It brings some advantages into traditional mode of distance education, with which learners can study anytime, anywhere. Now learners can take part in online learning, online exam, online discussion, online query and online communication as well, even at home. This instructional mode can provides learner with a rich and colorful interactive interface which is made of both images and texts, and with a huge repository of knowledge and information which can stimulate learners to learn; so that learners can construct knowledge depending on their own initiatively and get, renew, enen innovate knowledge by themselves, those aims belongs to our dreamboat.But there still are many problems in the online instruction system nowadays, first, the functions of active interaction in existing instruction system are not strong enough, and most of them are given mainly to present the instruction materials. Second, the system's intelligence is lower. Three, the testing and evaluating functions of the system are not good enough. Four, there is not an effective guide to students in existing system. Five, in the main constructions of existing online instructive systems are C/S constructions, causing that the client end is too huge. Furthermore, the resident program may operate the client end at will, causing that the unsafe factors of the system are added.In view of defects above, the author of this thesis designed a new kind of personalized system of distance education, which is based on Agent technology. Firstly, the Agent technology of DAI field is adopted in this new system to system to build a learner's Agent, which can not only trace the learning course of learners at any time and record their personality characters such as interests, favorites, etc., but also adjust the instructional strategy used for learners. So it has got rid of the lower intelligence defects of existing system...
