【摘要】 进入信息时代以来,计算机已经成为教育活动中密不可分的重要组成部分,教学活动也得益于计算机的辅助。组卷系统作为一种计算机辅助教育软件,其作用是运用计算机技术并按照试卷规格,从试题库中组合相关试题形成试卷。它是计算机管理教学(Computer Managed Instruction, CMI)的一个重要组成部分,并成为该领域的研究热门之一。常见的组卷系统往往只关注于形成试卷本身,所组试卷通常无法达到较高的专业水平,且系统多采用单机形式,缺乏资源共享与协作能力。基于以上分析,本文认为,组卷过程是一个从试题形成,到题库组织,直至组成试卷并分析反馈的周期性复杂过程。并以教育评价与教育统计理论为基础,构建了一个基于RIA(Rich Internet Application)的多角色协作组卷系统模型,此模型涵盖了上述全部组卷过程,并同时具备资源共享和多人协作组卷能力。最后应用.NET框架技术,并结合Flash Remoting技术实现了此模型。本文主要贡献如下:(1)在教育评价理论基础上提出了“试卷生命周期”的概念,并在此概念基础上提出组卷三阶段:试卷雏形阶段(即试题阶段)、试卷形成阶段、试卷消亡阶段;(2)结合工作流概念,提出“基于RIA的多角色协作组卷模型”,建立模型并设计与实现。(3)模型特点如下:①建立在试卷生命周期之上,完全覆盖整个试卷的活动周期;②本模型克服了之前组卷系统的一些不足,如:题库封闭性、组卷算法不合理等。③此模型提供了三个题库:核心题库、公共题库、私人题库,分别起到了不同的作用;④模型运用RSS技术,使得信息的发布更加快捷与高效,同时使得工作流的执行更加顺畅;⑤模型运用了RIA技术,简化了应用部署同时提高了客户端运算能力。更多还原

【Abstract】 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.更多还原
