Preliminary Study of Item banking System for Japanese Test as a Foreign Language for International Students

本研究对日语测试题库的开发进行了研究。报告首先简要介绍了日本高校在项目开发和考试管理方面的现状。本研究的主体部分介绍了试题库的必要性，并介绍了经典测验理论和项目反应理论用于项目分析。题库是管理和分析测试项目的集合，以供目标人群使用。该银行还包含有关这些项目的信息，并使用潜在特质测量程序将它们与常见的难度量表联系起来。题库通常用于(1)构建等同的或替代形式的频繁管理的标准化测试；以及(2)作为计算机适应性测试的基础。对题库的要求是：足够的测试题库，每个项目声称要衡量的能力和内容的清单，以及在测试试验中表明每个项目特征的统计数据，以及能够解释从库中项目构建的任何测试的分数含义的能力理论。

This research reports on the development of item banking of Japanese language tests. The report begins with a brief introduction to the current situation of item development and test administration of Japanese colleges and universities. The main part of the research describes the necessities of item banking and introduces classical test theory and item response theory for the item analysis. An item bank is a collection of test items administered and analyzed for use with an intended population. The bank also contains information about the items and links them to a common difficulty scales using latent trait measurement procedures. Item banks are commonly used (1) for the construction of equivalent or alternate forms of frequently administered standardized tests; and (2) as the basis for computer adaptive tests. The requirements for an item bank are an adequate pool of test items, an inventory of the abilities and content which each item purports to measure, and statistical data indicating the characteristics of each item as evidenced in test trialling, and a theory of ability which enables the meaning of scores on any test which may be constructed from the banked items to be interpreted.
