| Nowadays,the Web-based education is a new instruction form.The learners can choose when and where to study, which manifests the incomparable advantage.However, in most of the current web-based instruction systems, many disadvantages exist, for example, a lack of necessary interexchange function, a lack of individuality and self-adaptation, and a low intellectuality. The Agent technology is a software entity bearing autonomy, sociability and reactivity. Therefore, the development and application of the intellectual web instruction platform based on Agent technology, is a key step to the intellectualization of Web-based education.First of all, taking in the advantages of the current Web-based instruction systems, the author proposes a Web instruction system based on agent technology guided by constructivism education theory. And this system owns self-adaptation to some degree.The model in it is a hierarchical multi-agent system. The model autonomously produces a teaching strategy fitting the student, by using the intellectual inferring ability and taking the learning individuality of a student into consideration, and then based on the produced strategy it organizes teaching procedures intellectually. The design of the model could not only fully realize the cognitive subject role of the students but also guarantee the leading role of teachers in the learning process.As the student module is of great significance, the author puts forward a student agent model through analyzing the related factors.This model depicts comprehensively the features in five aspects which are knowledge domains, cognitive levels,learning styles, interests and learning emotion of students.It describes the personal features of students while learning, therefore not only catering to students but also enlightening them. |
