摘要

随着计算机技术和网络技术的飞速发展，网络在教育领域发挥越来越大的作用，产生了网络教学这一新的教学模式。网络教学作为现代教育的一个重要发展方向正在高等院校深入开展，但其教学效果并不尽如人意，缺乏高质量的通用的网络教学管理平台是其中的重要原因之一。

在分析了国外网络教学管理平台的开发现状的基础上，设计与实现了一个基于J2EE技术的通用网络教学管理平台。系统设计和实现中所用工具和技术：Rational Rose 2003、viso2003、PowerDesigner12.5 、Oracle10g、Struts2和Hibernate3。系统实现的主要功能如下：1、管理员对教师、学生、班级课表、班级、公告信息的增加、删除、修改、查询、批量导入等功能。2、教师发布并管理课通知，管理上传的各种学习资料，布置学生作业，评定并管理学生在线提交的作业，在线解答学生的疑难问题，参与学生的课程论坛讨论并管理学生的讨论容等功能。3、学生可以查看教师发布的通知，查询并下载教师上传的学习资料，也可以在线观看教师上传的学习视频，查看教师布置的作业并提交未过期的作业，也可以查看教师的评定、展示精品作业，向教师提问疑难问题，参与课堂讨论等功能。

本文设计的网络教学平台由系统后台管理、教师教学管理和学生学习管理三个子系统组成。它具有以下特点：一是操作简便，界面友好；二是功能较全面；三是功能较强大，具有通用性，能够满足我们学院日常教学的要求，具有较强的应用价值。

Abstract

With the development of computer and network technology, the network plays more and more important role in the educational fields，So this new educational model，networking education model occurred. 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 platform．Based on the analysis of present situation of network teaching platform development in the domestic and foreign，this system has been designed and realized universal network teaching management platform using the J2EE technology．During the development and realization of The Network Teaching Platform , the follows tools and technology are used .Such as : Viso drawing tool, Rational Rose 2003, PowerDesigner 12.5, Oracle10g , Struts2 and Hibernate3 and so on．The functions of the system are follows: First, administrator adding, deleting querying and altering teacher information student information, class information, class course tables, bulletins and importing the above information with Excel. Second, teacher releasing and managing inform, managing all kinds of the uploaded study materials, giving homework, correcting homework and giving comment, answering student’s problems online, taking part in student’s discussion and managing the content. Third, student can receive the teacher’s notice, query and download the study materials uploaded by teacher and student can also watch the study video online and view homework given by teacher and submit the not expired homework. Moreover, student can view the teacher’s comment and the excellent homework, ask teacher for questions and participate in the class discussion too.

The network teaching management platform is composed of three subsystems，the administrator management，the teacher teaching management and the student study．The platform has the following features：First，the operation is simple and the surface is friendly；Second，the platform is comprehensive in function；Third, the platform with power function and has the universal characters can meet the requirement of the teaching activities of our college so this system has strong application value.
