Research And Development, Based On The Ria Multi-role Collaboration Grouping System

As the world is approaching the information age, the computer is already become the necessary importance in the activity to education; the teaching activity is also received benefit to a computer of assistance higher effect. Test paper auto-generation is one kind of computer based education software, and its function is to combine test questions which come from question database into a test paper according to the specification by using computer. As one of Computer Managed Instruction important component, this system already becomes the major topic of discussion that field studies.The common systems only pay attention to the form test paper itself, and the test paper is usually unable to achieve a higher specialized level. In addition, these system always use the single plane form to be short of resource share and the ability cooperating. Analyzes based on above, this article believed that the test paper auto-generation process is from the test question formation, to question database organization, until composition examination paper and analysis feedback's periodic complex process. Taking education appraises theory and the education statistical theory, this article construct a model which is based on the Internet, and this model cover all process mentioned above, simultaneously having resources sharing and the multiple roles cooperates system model. At last, realize this model combining with .NET Framework technology and Flash Remoting technology.This text is mainly contributed as follows: (1) Put forward the concept of "Test Paper Life Cycle" in an evaluation theory foundation, and put forward a set of test paper auto-generation's three stages on this concept foundation; (2) Combine the concept that the work flows model, propose a system model based on multi-role cooperation test paper auto-generation model, and realize this model. (3) Model characteristics is as follows:①Establish a system model on"Test Paper Life Cycle", and this model completely overlay the whole movable period that test paper generation;②The model overcame some shortage of previous test paper generation system;③This model provides three databases: Core database and public database and private database, and had a different function respectively;④The model makes use of a RSS technique and make releasing of information faster with efficiently, the performance making to work to flow at the same time is more smoothly;⑤The model made use of a RIA technique and combined B/S mode and the advantage of C/S mode.
