标准参照测验中标准设定的聚类分析法

针对标准参照测验中标准设定存在的问题,本文探讨了一种客观化标准设定方法:聚类分析法,该法基于客观的实际测验数据,采用数理统计手段确定分界分数。首先阐述了聚类分析法应用于标准设定的逻辑基础,随后探讨了基于聚类分析设定分界分数的基本方法和步骤,尤其是如何检验聚类分析法的有效性。结合已有实证研究讨论了聚类分析法的优点与不足,并对聚类分析的应用提出了若干建议。

Standard Setting in Criterion-referenced Test: A Cluster Analysis Method

In order to solve the problems of standard setting in criterion-referenced tests,a new objective standard setting method,known as cluster analysis,has been developed. Based on objective empirical testing data, this method uses statistical procedure to set the cutoff score. In this paper,we firstly discussed the logic of applying cluster analysis in standard setting and then demonstrated the basic steps and procedures to apply the method,in particular how to test its validity. According to the empirical stud...
