The teaching itself involves the factors , such as environment to learn theory , educational psychology , and study ,etc.. A high-quality network teaching website must combine the education expert and specialized information engineering personnel with education speciality , doing the part of one's own speciality each, the education expert designs the teaching schemes needed on the teaching platform, the information expert offers a function interface apt to use to a education expert , do not look for only suitable teaching theory in the specific field to design the system at will . Probe into the teaching activity type that the regular meeting uses the education expert's teaching scheme mainly in this research, including webpage teaching material , person who comment test, on-line homework , topic discuss and is it study as how 's merger give teacher make it plan the teaching activity not to used for activity to cooperate in, and do further treatment to teacher's designed teaching scheme. Not only can protect the advantage with network teaching like this , can also avoid the shortcoming on network teaching , for instance: (1)The beginner is apt to lose the study direction, result in studying the setback ; (2)The aimless one is had a look around, it is unable to build and construct the intact knowledge structure; (3)Cognitive question that overloads ; (4)The knowledge structure is difficult with question that is combined ,etc.. So this research is made in fact: First, offer a interface of course progress to a teacher's editor, the teaching activity of planning course that enables teacher easily , implement teaching tactics of teacher in order to reach automation , teaching of goal arrange system. Second, the inter dynamic increasing between the system and user is designed. After teacher establish course arrange, information notify system will convey teacher or message that student correlated with to in accordance with different situation in advance.

Because of the development of the Internet, there are more and more users. Various kinds of services are provided by companies. They are usually web based for easy use. The performance of web servers is a key factor of the quality of services. In a user¡¦s view, the response time is a important metric for the performance of a web server, so we implement a passive performance evaluation tool for web servers in this paper. In this paper we discussed phenomenons when bottlenecks at a web server occur. We make experiments to show how bottlenecks in the CPU, network, and in the Disk can affect the response time. The result shows that response time is affected in different way according to the type of the request when the bottleneck is CPU, network or disk.
