The Design And Development Of The Computer Distance Learning System Based On CORBA

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.
