摘要
基于Rasch模型对化学实验操作技能测试的评分者效应开展研究。通过对Infit、Outfit、t、怀特图和宽严度波动图等的分析,研究测试中评委的宽严度、内部一致性、外部一致性以及评委与考生间的偏差规律。得到系列减弱化学实验操作技能测试中评分者效应的建议。
Based on Rasch model, we studied the rater effect of operational skill test in chemical experiment. The rules of leniency, internal consistency, external consistency of raters and the deviation between raters and examinees were researched through analyzing Infit, Outfit, t, White charts and leniency fluctuation charts and so on. A series of suggestions to weaken the rater effect of operational skill test in chemical experiment were obtained.
