【摘要】 网络教育作为一个新兴的教育模式,现在已经成为了除统招本科教育外最重要的教育模式之一。网络教育从产生到现在短短6年发展时间,从事网络教育的大学从4所发展为67所,已开设9大类153个专业。如此迅猛的发展速度,意味着网络大学这所没有围墙的学校已得到社会的广泛认可,并且为日后人们进行“充电”和终身教育提供了又一较为便捷的途径。目前,全国网络大学的学生人数已从去年的160万增加到目前的近250万,增长人数近一倍。随着网络教育的发展,网络资源建设已经成为网络教育的重点。网络教育资源通过网络的连通,为人们提供了一种高效、便捷的施教、学习、管理和服务的途径,从而打破教育过程在时间和空间上的限制,大大推动网络教育的发展。网络资源是指通过互联网将分布在不同地方的计算机硬件资源、软件资源和各种信息资源组成充分共享的资源集成,其中与教育相关的资源称之为网络教育资源。如何适应网络教育的特点来整理好网络资源,如何更好的为教学服务,已经成为了刻不容缓急需解决的问题。而电子科技大学网络教育学院是2002年由教育部办公厅[2002]2号文件批准成立的,学院在近年的快速发展中,同样遇到了上述问题。本论文就是对基于网络的网络资源系统进行研究,同时提出资源系统应该更好的为网络教育教学服务的思想,并且予以开发实现。本论文所论述的基于ASP的网络教育资源系统以其特有的优势成为以上问题解决的关键手段。本文的研究内容及其主要创新之处可概括如下:首先,分析了当前网络教育资源的现状及其实际应用情况,总结出所存在的一些问题,在此基础上确定了系统的实现目标。从系统的实际使用情况出发,确定以传统的C/S模式作为系统开发的体系结构,给出了系统的功能模块结构。其次,详细论述了系统的具体实现方案以及开发过程中所涉及的一些关键技术。为了保证资源系统的最好利用,对搜索算法和ASP的缓存技术做了一定的研究,提出了解决搜索问题和资源利用问题的一些措施。所有客户端都能在系统平台上实现教学互动。最后,对系统存在的不足做出了分析,提出了相应的解决方案,为系统进一步的完善和应用打下基础。更多还原

【Abstract】 Network education as a new mode of education has now become a unified undergraduate education, in addition to the most important one of the mode of education. Network education from birth, now just six years of development time, network education in the universities for the development of four from the 67, nine have been created by 153 professional categories. Such rapid pace of development, and this means that the networks do not have the wall of the school community has been widely recognized, and people for the future "charged" life-long education and provide a more convenient way for another. At present, the National Network of the University of the number of students from last year’s 1.6 million to the current nearly 2.5 million, an increase of the number nearly doubled. As the network of education in the development, the building of network resources has become the focus of the Education Network. Network of educational resources through the network connectivity, providing people with an efficient and convenient teaching, learning, management and service channels, thereby breaking the educational process in time and space constraints, greatly promote the development of education. Refer to network resources through the Internet would be distributed in different places resources of the computer hardware, software resources and various kinds of information resources component fully integrated shared resources, and education-related resources as network resources for education. How to adapt to the characteristics of network education, collating network resources for teaching how to better service has become urgent need to solve the problems. Network and the University of Electronic Science and Technology Institute of Education in 2002 by the Ministry of Education is the Office [2002], approved the setting up of the 2nd, and the rapid development in recent years, encountered the same problem. This paper is based on the network of networks resources systems research, resources At the same time, the system should better educational services for the network’s ideology, and to achieve development. This paper examines the ASP-based educational resources in the network of its unique advantages become more critical means to solve the problem.The main contents and originality in this paper can be summarized as follows: Firstly, this paper analyzes the current network of educational resources and the status of the application, summed up the existence of some problems in the system, based on the achievement of targets. From the actual use of situation and determine the traditional C / S system as a model the development of architecture, given the function of the system module structure.Secondly, this paper discusses in detail the specific system to achieve programmes, as well as involved in the process of developing a number of key technologies. In order to ensure the best use of system resources, the search algorithm and ASP cache technology to do a certain amount of research, problem solving search problems and the use of resources of some of the measures. All clients can achieve in the system platform interactive teaching.Finally, this article the shortcomings of the system has made analysis of the corresponding solutions for the system to further improve and lay a foundation for improved.更多还原
