Network Teaching is the product of puter and network munication technology that has been applied to the field of teaching where instruction is achieved remotely through a network. It can give full play to the advantages of networks in teaching, and also fully embodies the studentcentered, teacher led philosophy. This is a new mode of education in the era of knowledge economies to let a person whole life learning. It is a trend in the development of future educational systems.This paper has its basis in the extensive research done on the status quo of network teaching in China and other countries. We have designed and implemented a network teaching system based on web technology to meet the actual needs of Shandong College of Electronic Technology. We used Rational Unified Process (RUP) software development methods, the Unified Modeling Language (UML) for the analytic design description language, and the Microsoft .NET Framework for the technology platform. Specifically, the network teaching system uses the B/S architecture and runs on Window Server 2003, IIS with , and SQL Server 2005 backend database. The frontend was developed in Visual Studio 2005. This system is a practical network platform mainly intended for learning, teaching, and management functions. With this platform we can make full use of network resources to facilitate students’ learning and teachers’ teaching and managing.This paper briefly describes the main problems that need to be solved in the network teaching system by analyzing its development background and current status quo. It also analyzes system functional requirements and nonfunctional requirements and processes a systematic design based on demand analysis. The database is exported to a system static model class diagram and gives a detailed description of the design of three major functional modules (middle school students, teachers and administrators). It discusses in more detail the technical specifics of the system and the main functions of the system modules, and illustrates part of the system interface and processes.Finally, the paper summarizes the development and design work and discusses the need to further develop and expand the system.Keywords: Web。 Network teaching system。 III第1章 緒論隨著科學技術(shù)的進步，尤其是計算機網(wǎng)絡(luò)的發(fā)展，人類將進入信息社會，因此人們的生活方式、工作方式，以及教育方式都將隨之改變。末來的教育技術(shù)必然將重點放到以信息技術(shù)為基礎(chǔ)的網(wǎng)絡(luò)教育技術(shù)上。網(wǎng)絡(luò)教學是指利用計算機網(wǎng)絡(luò)技術(shù)與多媒體技術(shù)，在網(wǎng)絡(luò)環(huán)境下開展教學的方式。網(wǎng)絡(luò)教學是現(xiàn)代遠程教育的一種表現(xiàn)形式，現(xiàn)代遠程教育是從20世紀后半葉逐漸發(fā)展起來的一種新型的教育形式，它經(jīng)歷了傳統(tǒng)的函授教育和以廣播、衛(wèi)星為媒體傳送教學內(nèi)容的教育形
