摘　　要：测验等值是我国考试改革亟待解决的重大技术问题,而铆测验设计是等值技术的核心环节。结合我国学业水平测试特点,采用模拟研究方法,探讨铆测验内容代表性、题目难度分布对多维混合题型测验等值精度的影响。结果表明:铆测验内容代表性对各参数等值结果影响显著,与被等值测验维度相同,即内容代表性最佳的铆测验等值精度更高;铆测验的题目难度分布对各参数等值结果有一定影响,在大部分条件下,当难度参数的分布是被等值测验的50%或20%时,等值精度更高。该研究为我国学业水平测试等值体系建立、铆测验设计开发提供了方法学依据。Test equating is a crucial technical problem to be solved urgently in China’s examination reform,in which anchor test design is the core link.Based on the characteristics of the academic proficiency test in China,the present simulative study aims to explore and discuss the influence of the representative content of the anchor test and the difficulty distribution on the equating accuracy of the multidimensional mixed-format test.The results showed that:1)the effect of content representativeness of the anchor test was significant,which means the anchor test with the same dimensions as the base test was more accurate in equating;2)the distribution of difficulty parameters of anchor items affected the results of equivalent parameters,namely,under most conditions,the equating accuracy was higher when the distribution of difficulty parameters was less than or equal to 50%of the base test.The research provided a methodological basis for establishing the equivalent system and designing and developing anchor tests in China.
