摘要 考察在IRT理论框架下,选用不同的参数模型和评分模型对能力估计的影响.结果发现:对同一批被试,不同的参数模型会得出不同的能力估计值;模型误用会带来能力估计上的误差,某些情况下误差相当大;能力估计的具体方法和技术也会对最终的能力估计值产生影响. When different IRT parameter models and scoring models are used, the research finds: (1) the same ability resuits in different ability estimator under different parameter model or different scoring models ; (2)the misuse of models results in the error of the ability estimation , sometimes the error is serious ; (3) the ability estimation techniques impact on the estimator.
