| 摘 要： | 针对两种测量理论(CTT和IRT)统计结果之间存在的相关性,提出在题库建设中试题难度参数确定上,以IRT在试题参数测试的不变性为基础,充分利用CTT的优点,取两者之所长,将两者有机地融合,使确定的难度系数具有客观性和科学性.

| Abstract: | This article uses the relevance of statistical results of two kinds of measurement theories(CTT and IRT),and proposes that the method of defining the parameter of Difficulty coefficient in building test bank should be based on the invariance of item parameter estimates in IRT,by making full use of the advantage of CTT,combining the two by taking the merits of them,the purpose of defining the parameter of difficulty coefficient objectively and scientifically shall be realized. |
