System development for educational test data analysis

本研究开发了教育考试数据管理系统。所开发的系统使我们能够估计各种类型的项目的参数的基础上项目反应理论，这是广泛应用于心理学和教育心理学。在这项研究中，1。编制了项目反应理论的参数估计程序。2.建立了多元贝塔分布的数学模型，并给出了该分布的有限夹具分布，该分布覆盖了多元测试分数的整个范围。3.该系统通过WEB服务器向被试展示试题，并存储被试的回答。

In this research, the system for educational testing data was developed. The developed system enables us to estimate parameters of various types of items based on Item Response Theory which is widely used in psychology and educational psychology. In this research, 1. The parameter estimation programme for Item Response Theory was developed. 2. Multivariate-beta distribution was formulated, and the finite fixture distribution of the distribution was also proposed, which covers entire range of the multivariate testing scores. 3. The Computer-based Testing system has been developed, which shows items to respondents via WEB server, and stores responses of the respondents.
