The Design And Implementation Of Web-based Networking Learning Platform

The development along with the high speed in computer network technical makes that mankind have a new teaching approach: Teaching on the internet. The new method with this kind of teaching has become important to the system constitution and the network teaching platform in parts of university and the network-based university. The environment for completing the teaching mission on internet also becomes the popular technique in present. But due to the restrict of the hardware and software resources in network, the development of the network teaching platform demands to rise an environment for handing over with each other, opening and easily using, and wants to be with the possibly cheap devotion but teaching performance acquiring possibly and efficiently. For attaining these two targets, we shall be good to proceed the design and development of the networks teaching platform .In present, the network teaching platform based on the web ( non-real time network teaching platform) is the most economical and practical . This text researches the design and development of the network teaching platform based on the web. The need, technique and realization of the network teaching platform is special important in this paper. This paper first analyzes three kinds of roles' main need of the network teaching platform. The three kinds of roles are: student, teacher and administrator From the student view, the network teaching platform should provide the functions that students can select elective courses, take a look at the lessons and study online, complete the homework online ,hand over the homework and inspect the result online, test online and so on. Saying from the teacher's angle, the network teaching platform should provide the functions that teachers can spread the lessons, manage the lessons, and delete the lessons; It also should provide the functions that teachers can set questions and put them to the question library online, select questions from the library and then form the homework and test papers, discuss with students in the area of discussion and so on. The network teaching platform should provide the functions that administrator can manage the teaching resources, public notices, and customers and so on.In the aspects of practical technique of the network teaching platform, this text emphasizes to introduce the " three tier C/S" model that the network teaching platform based on the web usually uses, this kind of model puts various teaching resources in the server, and uses the center database to unify to deposit and organize , customers are in client machine, they don't need to do any configure, they only need to request WEB server agent with browser, the server connects with the background database by middleware after examination, then the server passes the teaching courses back to customers with the WEB page form by the browsers, client forms the next application by operating the page. This paper introduces several parts of the "three tier C/S" model later: the client, the application server, the realization technique of the database server and the application on the network education platform.Later, this paper designs and realizes the 'Jilin University education online'. It analyzes the realization of the actual network education platform, and the realization codes and the contracture of the procedure of the network education platform according to the four parts: general module, teacher space module piece, student space module, and administrator workroom module.
