System development for educational test data analysis

在本研究中，开发了教育测试数据系统。该系统使我们能够基于心理学和教育心理学中广泛应用的项目反应理论来估计各种类型项目的参数。在本研究中，1。开发了项目反应理论的参数估计程序。2. 建立了多元beta分布，并提出了该分布的有限固定分布，该分布覆盖了多元检验分数的整个范围。3. 开发了基于计算机的测试系统，该系统通过WEB服务器向被测者显示测试项目，并存储被测者的回答。

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.
