基于校園網(wǎng)的網(wǎng)絡(luò)教學(xué)平臺——學(xué)生自主學(xué)習(xí)子系統(tǒng)設(shè)計與實現(xiàn)

摘 要
隨著計算機技術(shù)和網(wǎng)絡(luò)技術(shù)的飛速發(fā)展，網(wǎng)絡(luò)在教育領(lǐng)域發(fā)揮越來越大的作用，產(chǎn)生了網(wǎng)絡(luò)教學(xué)這一新的教學(xué)模式。網(wǎng)絡(luò)教學(xué)突破了傳統(tǒng)教學(xué)的時空限制，對傳統(tǒng)的以課堂教學(xué)為核心的教學(xué)模式產(chǎn)生了巨大沖擊。網(wǎng)絡(luò)教學(xué)已成為現(xiàn)代教育的一個重要發(fā)展方向。
網(wǎng)絡(luò)教學(xué)正在高等院校深入開展，但其教學(xué)效果并不盡如人意，缺乏高質(zhì)量的通用的網(wǎng)絡(luò)教學(xué)管理平臺是其中的重要原因之一。
本文在分析了國內(nèi)外網(wǎng)絡(luò)教學(xué)管理平臺的開發(fā)現(xiàn)狀的基礎(chǔ)上，設(shè)計與實現(xiàn)了一個基于J2EE技術(shù)的通用網(wǎng)絡(luò)教學(xué)管理平臺。平臺采用瀏覽器／服務(wù)器(Browser/Server)模型，應(yīng)用MVC(Model-View-Control)模式設(shè)計系統(tǒng)結(jié)構(gòu)，通過Struts和Hibernate框架來實現(xiàn)，采用面向?qū)ο笳Z言Java開發(fā)實現(xiàn)，并使用關(guān)系型數(shù)據(jù)庫SQLServer2000作為數(shù)據(jù)庫管理，為今后系統(tǒng)的移植性，跨平臺使用，系統(tǒng)維護、功能擴展方面做了充足的準備工作。
本課題在對網(wǎng)絡(luò)教學(xué)平臺的認識與對目前網(wǎng)絡(luò)教學(xué)平臺的應(yīng)用情況分析的基礎(chǔ)上，以實施自主學(xué)習(xí)能力培養(yǎng)策略為論文出發(fā)點，設(shè)計一個以培養(yǎng)自主學(xué)習(xí)能力為特色的網(wǎng)絡(luò)教學(xué)平臺。在功能上實現(xiàn)了管理模塊、教師模塊、學(xué)生模塊、交流模塊、自主學(xué)習(xí)支持模塊五大模塊。系統(tǒng)將課程內(nèi)容、講義、學(xué)習(xí)策略、學(xué)習(xí)技巧、自主學(xué)習(xí)認知工具等有效地集成為一體，使學(xué)生在課程學(xué)習(xí)的過程中，學(xué)會合理的規(guī)劃網(wǎng)絡(luò)學(xué)習(xí)、高效地利用網(wǎng)絡(luò)學(xué)習(xí)時間，養(yǎng)成自我監(jiān)控的良好習(xí)慣，以提高學(xué)生在網(wǎng)絡(luò)環(huán)境中的自主學(xué)習(xí)能力。

Design and achieve of network teaching platform Based on Campus network——Student independent study sub-system
Abstract
With the development of computer and network technology,the network plays more important role in the educational fields,so this new networking education model occurred. The network teaching has broke the limits of the traditional teaching space and time and had the huge impact on the tradition teaching of taking the classroom instruction as the core educational model.The network teaching is regarded as an important development direction in the modern education.
The network teaching is developing thoroughly in university,but the teaching effect is not entirely satisfactory.One of the most important reasons is the lack of the high quality universal network teaching management platform.
Based on the analysis of present situation of network teaching management platform development in the domestic and foreign,this article has designed and realized universal networkteaching management platform using the J2EE technology.Based on Browser /Server model,the platform has been designed with MVC(Model-View-Control)and realized with J2EE technology using Struts and Hibernate technology to achieve.Using obj ect—oriented language Java development to achieve,and the use of relational database SQLServer2000 as database management,systems for the future of transplantation,the use of cross platform,system maintenance,extensions done a sufficient preparations.
Based on the understanding and the analyses of network education platform，this research takes the strategies of cultivating the ability of independent study as its chief purpose.It has achieved five modules including management module,teacher module,student module,communication module and independent study supporting module.The system has made the contents,the education materials,the learning strategies,the learning skills and the cognition approaches of independent study into all integrated whole.This enables the students to plan network study well and make full use of network study.In this way they can fester the habit of self-monitoring to improve their abilities of independent study.
