摘要:
在3PLM模型下,将改进的最大优先级指标(MMPI)方法和各类平均数形式相结合得到的4种新选题策略在提高测验精度、控制项目曝光均匀性、降低平均违规次数、提高题库利用率等方面均表现更好.经定长测验和不定长测验的蒙特卡洛模拟,MMPI下算术平方根平均数形式的选题策略表现最优.
Abstract:
A new item selection strategies named MMPI with four kinds average types on 3PLM has been put forward.The results of Monte Carlo simulations of fixed length tests and variable length tests show that the MMPI with four kinds average type approaches are more ideal in the performance of improvement the test precision,control the exposure uniformity,reducing the average number of violations and improve the bank utilization.Especially,the MMPI with root square of arithmetic average type is the best one.
