为了探究TEM-4作文评分员的评分效应,我们运用项目反应理论的多层面Rasch模型,对25位TEM-4评分员的严厉度、集中趋势、随机效应、晕轮效应以及在考生和评分量表3个维度上的偏差进行了分析。结果表明:TEM-4评分员的严厉度存在显著差异;评分员自身一致性较好,不存在明显的集中趋势,个别评分员存在随机效应和晕轮效应;评分员与考生和评分标准各维度之间存在明显的偏性交互作用。
To explore the scoring effect of the TEM-4 essayist, we used the multi-level Rasch model of the project response theory to evaluate the severity, concentration, randomness, halo effects, The deviations in the three dimensions of Table 3 are analyzed. The results showed that there was a significant difference in the severity of the TEM-4 scorers. The scorers themselves were in good agreement. There was no obvious concentration tendency. The individual scorers had random effects and halo effects. The scorers, There is a clear bias between the interaction.
