【摘要】 本文在综观国内外远程教育发展现状的基础上,分析比较了在Internet上远程教育的几种不同的Web交互机制:CGI/HTTP,Java Scoket,Web API,Java RMI。通过对以上机制的优缺点分析,阐述了在CORBA/Java基础上构筑远程教育系统的方法和优势:利用CORBA技术处理网络的异构性,可以实现异构系统之间资源的共享和信息交换,从而在技术上较好地解决了远程教育网上分布式资源的共享问题。同时对于网上教学模式选择,本文倡导一种混合双主教学模式,提出行为主义,认知主义,建构主义三大学习理论并不是相互替代的关系,而是应该有机的结合在一起,共同为提高学生的综合能力和学习效率提供丰富的教学机制。然后依据这种模式建立了一个基于CORBA的分布式远程教育系统的C/A/S模型框架,并针对其内部教学平台的实现,进行了详细的设计和开发。
【Abstract】 After making a comprehensive view of the nowadays development of distance learning, this paper analyses and compares several different kinds of interaction forms on the Web for Internet-Based distance learning: CGI/HTTP, JAVA Socket, Web API, Java Rlvll. Through the analysis of the advantages and disadvantages of the above-mentioned forms, it illustrates the methods and advantages of the Internet-based distance learning on the basis ofCORBAIJAVA:Availing of the heterogeneous system of CORBA processing, it can realize the share of resources and exchange of information among the heterogeneous system, thus technically solving the problem of the share of distributed resources on the Internet-based distance learning system. At the same time, for the selects of teaching pattern on net, this paper advocates a double-dominated teaching pattern: The relationship between the three learning theories, behaviorism, cognitivism and constructivism, should not be the one of replacing each other. Instead, it should be combined organically to provide various teaching patterns in order to improve students?comprehensive ability and study efficiency. Then, according this pattern, this paper builds a CIA/S model skeleton based on CORBA distributed distance learning system. In the light of realization of its internal teaching platform, a detailed design and deplore is carried out.
