基于E-school虚拟学校平台的技术研究

摘     要

在最近几十年来，互联网正在以惊人的速度覆盖我们生活的各方各面。在互联网的支持下，人们可以高效率的进行信息搜索。并且可以在任何时间与任何地点的互联网上的用户进行信息的交流。由于互联网的出现使得人们的生活习惯以及传统逐渐发生了变化。娱乐，工作，交友以及学习都无不因为互联网这个巨大的信息传输工具在发生变化。而E-school这种新型的传播平台则在这个时刻孕育而生，并且正在成为全球企业、教育机构和政府机构认真对待的新事物。在对网络教育这个全新的概念做一番研究之后，我设计了一套虚拟教学平台，为的是改变传统教育模式，突破了时间和空间的限制。开放型、交互性、协作性、自主性等特点使网络教育既成为一种教育手段、也是一种学习方式又是一种教育理念，同时还是一种教学组织形式。

该平台针对现在的都市人网络使用频繁，但是由于工作和学校学习繁忙，很少能有时间学习自己感兴趣的内容。为此特别设计了“E－SCHOOL”这个网上虚拟学校，为上班，上课的都市人创造的一个可以自由选择学校，课程，老师以及上课时间和地点，并且可以在任何时候任何地点网上管理自己的日程安排和资料信息的B/S网站系统。而针对学校的管理和组织者而言，这个平台也方便了进行学校课程的开办以及学生、老师方面的管理。做到管理的自动化，网络化和动态化。

而我在该项目中主要采用MYSQL数据库进行整个网站的开发工作。并且同时进行了网页的设计，然后使用dreamwaver等网页编辑工具完成网页的基本框架以及网页结构图。之后在其中添加相应的jsp代码来完成显示页面的设计。同时整个网站我采用了MVC的结构模型制作软件。这样可以充分体现网络平台的个性化特点。其中每一个学校都有自己的相关主页，并且都有自己的班级和课程的页面，而用户只要登陆网站就可以进行各个页面的浏览而且可以选择自己想要参加的课程以及班级。以上这些流程都在正式开发之前我已经经过了一定时间的整理以及思考完成了一份比价完善的需求分析。而在前期准备之后我在代码开发时期充分使用了jsp网站的mvc模型进行了网页与控制管理分开处理的方法，使得页面的美工以及控制都可以顺利进行。其中我为所有的数据库操作以及一些数据的判断都专门设计了控制文件，而网页的视图层只是负责页面的美观，图片的调用等等显示功能。这样作可以让网站更便于进一步的扩展。为E-school今后能进一步改变人们生活，更人性化做好了一定的基础和准备。而在开发的后期我也进行了一定的测试，保证了已经完成的模块的功能可以正常使用

The Study On Key Technology of Virtual Teaching Platform Based On E-Learning

ABSTRACT

During the past several decades, internet is blanketing people’s life in every aspect at a tremendous speed. People are able to undertake information research efficiently and realize communication with the user in the internet at any time as well as in any place. Actually, the existence of internet gradually affects people’s life style and traditional ideas and meanwhile entertainment, working, friend-making and study etc, everything has been diversified with the development of internet---the huge information transmission tool. Under such circumstances, E-school, a new kind of platform, emerges, which is considered as a potential thing and seriously treated by global enterprises, educational institutions and government organizations. After doing comprehensive researches on internet education, I design a set of virtual educational platform, aiming at changing the traditional teaching style, overcoming the limitation of time and space. Openness, communication, cooperation, autonomy and so on, are the characteristics of the internet education, a new way of teaching and learning, a new idea of education as well as a new teaching organization.

MYSOL database is mainly used to develop and edit the whole web pages and those editing tools like dreamwaver, are for the purpose of its basic framework and construct drawing, jsp addition is followed consequently in order to realize page designing. MVC, a structural model, is as well as used to fully exemplify the individual feature of this network platform. Each school has its own homepage, with the page layout of classes as well as curriculum. Only to land the website, can users view the page and select the classes and courses they want to participate in. All of the progresses above have been arranged and analyzed for a long time and before my formal development, a relatively detailed requirement analysis has been finished. During the period of developing code, adopting of mvc model from jsp website aims to manage page and control separately. This enables the decoration and page control to go with a swing. Control documents are specifically designed for the operation and judgement of all databases, while view layers of the page are used to decorate some complicated pages and invoke pictures. In this way, it can provide a further development for the website and makes more possibility for E-school to change people’s life style and be more personalized in the future. Additionally, in the post period, related tests are made to ensure normal use of the templates.
