By using multimedia technology, a college physics multimedia courseware and a web teaching system are developed.

Web teaching system is not only an important area on the integ rated application of modern information technolog ies,but also a basic means of Educational Informationization.

a web teaching system is designed with Browser/Server mode, which consists of student registration on web, classes on web, questionnaire on line and mail boxes of teachers and students, customers studying the courses, random extracting test questions, marking in time, checking the record and correcting personal information through interaction.

This paper introduces several traditional online teaching systems, points out that the common weak point of these systems is the lack of individualization, and analyzes the online teaching system based on Agent technology which solves the problems existing in traditional online teaching system and is applied widely.

In this paper,an online teaching system is established by using Dreamweaver MX as website developing tool.

This paper discusses the teaching model based on autonomous learning,and presents a design scheme for network teaching system on the basis of autonomous learning.

Designs a model of network teaching system based on multi-agent,emphatically describes the system structure of three layered NTS with application layer,integrated layer,data layer,and communicative mechanism of multi-agents.

Network Instructional System(NIS) in the network technology,the paper high lights the "three-layer B/S" model which commonly was used to Network Instructional System(NIS).

With the rapid development of networks technology, especially the extensive application of Web technology, at the same time, massive construction of networks basic facilities and the imperious need of sharing the teaching resources, it becomes more and more important to construct the Network Instructional System.
