等值对考试具有重要意义,而我国的大部分考试却没有实现等值,在少数经过等值的考试中,大多只限于对二级记分题目的等值,鲜有对多级记分题目的等值研究。该研究针对包含多级记分题目的国内某大型语言类考试,探讨了等级反应模型下的同时校准法、固定共同题参数法以及链接独立校准法中的平均数标准差方法、平均数平均数方法、Haebara法和Stocking-Lord法六种等值方法的效果,从而优选最适合该考试的等值方法。
Equivalence is of great importance to the examination, but most of the examinations in our country have not achieved the equivalence. Most of the examinations passed through the equivalent are limited to the equivalence of the two-level scoring, and few have the subject of multi-level scoring. Value research. This study aims at a large-scale language test that contains a multi-level scoring problem, and discusses the method of simultaneous calibration, the fixed common problem parameter method and the average standard deviation method in the linked independent calibration method under the hierarchical response model, , The Haebara method and the Stocking-Lord method, so as to optimize the equivalent method most suitable for the examination.
