基于项目反应理论的HSK自适应分级考试系统

为了提供一个高效、准确的HSK分级考试系统,文中提出了一种基于项目反应理论的对外汉语教学（HSK）自适应分级考试系统。该系统基于项目反映理论,并以试题作为一个基本的测试项目。当测试开始时,测试者可以自选等级,系统根据受测者指定的等级从题库中随机抽取若干题目组成一套试卷进行测试,根据测试结果,使用本文中设计的基于项目反映理论的试题抽取算法自动向受试者推送合适等级的测试题目。当满足试题抽取的终止条件时,系统将给出受试者合适的HSK学习级别。通过对学生考查实验并进行模型分析表明,该系统具有测试准确、效率高的特点,达到了设计要求。

Adaptive grading HSK test system based on item response theory

In order to provide an efficient and accurate HSK grading test system,this paper presents an adaptive grading test system based on Item Response Theory for Teaching Chinese（HSK） and use questions as a basic test item. When the test begins, the test takers can choose the level. the system chose a set of papers composed by questions selected randomly from the base of questions according to the level chosen by the test takers. according to test results, the questions decimation algorithm based on Item Response Theory in this paper will automatically give the test question of appropriate level to the test takers.when the termination condition of question decimation is met, the system will recommend proper HSK level to the test takers.By experiment of examining the students and model analysis showed that the system has a test accuracy, high efficiency, and achieve the design requirements.
