【摘要】 在快速发展的计算机网络时代,计算机网络在各方面的应用越来越广。利用计算机进行网络教学已经成为计算机网络方面应用的一个很重要的方面。对多媒体和计算机网络技术的综合已经被应用到目前的网络教学中,它已经成为网络环境下,对信息资源进行共享的一个主要的方面,它是对传统的教学在空间和时间上的一个很大的扩展。在高等学校中,信息技术的应用占有很大的优势,建设网络教学的工作逐渐产生。目前,大部分的高等学校的针对校园网的硬件基础建设已经完成,针对网络教学建设工作,学校的各位领导对网络教学工作的建设和使用也有很高的重视度,规划和开发网络教学系统的工作也正在进行,所以,研究和开发网络教学平台对于教学工作是很有必要的。在这种情况下,本文提出了对教学平台的设计与研究。研究和开发网络教学平台,在提高教学的水平以及开发各专业网络教学课程等方面是有很大好处的,与此同时,也可以对学校教育的长远发展提供很好的基础。在对现在经常用到的网络教学平台调查和分析之后,借鉴国内外同类产品开发和研究的成果,设计了一个能满足目前大多数高校网络教学需要的教学平台系统。实现了管理模块、教务模块、教师模块、学生模块等的初步功能。系统在教师制作和利用网络教学课件方面做了重点介绍,同时,在校园网中,利用校园网的多媒体进行教学工作也很容易,为了能够同时方便学生的自学能力以及学生和教师之间的相互交流,我们设计了教师和学生的博客、聊天室以及提问功能。我们设计了网上在线测试系统,这个系统对教学效果的评价方面上非常有用的,在本文中,着重研究了在线测试的技术的实现以及组卷的算法。本文重点是对J2EE技术、MVC模式、开源代码工具以及设计所使用的架构Struts+Spring+Hibernate等方面的学习和研究。最后,在对这些技术和工具进行综合的应用之后,设计了一个网络教学平台的实例。经过改进的遗传算法虽然可以使生成试卷的质量得到保障,但是没有对组卷的收敛速度上没有任何的改进,这还得更进一步的研究。更多还原

【Abstract】 With the rapid development of computer and network, it came into being that all kinds of applications based on the computer network. Computer networks teaching is an important web application. Comprehensive application of computer network technology and multimedia network teaching of modern technology make traditional teaching functions being an extension in time and space, and it is an important aspect of service of sharing the information resources in Internet. Colleges and universities have built a network of teaching that has a unique advantage of information technology. The most colleges and universities is planning to develop teaching applications system based on campus Network, Because they have been building a good foundation for the campus network hardware, and the leadership attaches great importance to construction and use of teaching and learning environment. Therefore, the development and application of network teaching platform is important. This article is made in this context. Research and development of network teaching platform will be conducive to the professional courses in the teaching of the smooth network development and management to raise the level of teaching, as well as colleges’information to meet the long-term needs of development.This article designed a teaching platform which meet the needs of network teaching for most colleges and universities, based on the common network teaching platform and the analysis of the investigation, and the reference of domestic and foreign similar product development and research achievements. The system basically realize management module, educational administration, teacher module, student module and so on. At the same time, the system makes use of network teaching class in outstanding teacher and the functional carrying out campus network multi-media teaching conveniently, gives consideration to convenience teacher and student that the student learns and autonomously exchanging interactive need. The system has the chat room, the plentiful visitor and having asked questions. For the teaching-learning evaluation process is particularly useful for network test systems, test paper this algorithm in the implementation technology and focus on the study.Paper focuses on J2EE technology and the MVC pattern, the current design of the more popular way Struts+Spring+Hibernate framework, open source tools such as learning and research. Final integrated use of these technologies and tools for design of a network teaching platform instance. Application of improved genetic algorithm for generating test paper quality, has been achieved, but the convergence rate has not improved on paper, required further study.更多还原
