| 摘 要： | 总结了基于非等组锚题设计下的两大类IRT等值方法:同时参数标定和分别参数标定.分别参数标定包含了线性参数转换和固定参数标定,以等值精度为评价标准对这3类等值方法的效果和适用条件进行归纳并做出相应的评析,为测验工作者选择合适的等值方法进行项目参数和测验等值提供参考依据.

| Abstract: | Two kinds of methods in test equating has been commented:concurrent calibration method and separate calibration method.The second kind includes linking separate calibration methods(e.g.the moment methods and the characteristic curve methods)and FIPC(Fixed Item Parameter Calibration)method.Taking equating accuracy as the criterion,the effects and suitable conditions of each method are summarized and corresponding comments are provided.The reference for users will be prouided in selecting the appropriate methods to process test equating. |
