【摘要】：大规模教育考试的维度与考试分数的意义解释、考生在考试中的行为表现解释密切相关。利用非参数项目反应理论模型选择试题组成单维量表,可以达到研究考试维度的目的。选择单维量表试题时,下界c值的确定,是个值得探讨的问题。用非参数项目反应理论模型对英语考试的三个量表维度研究发现,从每一个量表中只能选择出一个单维量表,而不是与每一部分测量的微技能数相应的多个单维量表;每一单维量表测量的均为该部分不同微技能的组合。这个特征表明这些单维量表均为基本单维量表,非严格单维量表。无论c值为0.3,还是0.2,选择出的基本单维量表均满足弱单调性要求,整个单维量表的区分功能不会有明显差异。
[Abstract]:The dimensionality of large-scale educational examination is closely related to the meaning explanation of test score and the explanation of examinee's behavior in the examination. The non-parametric item response theory model is used to select the test questions to form a one-dimensional scale. Can achieve the purpose of studying the examination dimension. When selecting the single dimensional scale, the determination of the lower bound c value. Using the non-parametric item response theory model to study the three dimensions of English examination, it is found that only one single dimension scale can be selected from each scale. Instead of multiple one-dimensional scales corresponding to the number of microskills measured in each part; Each single dimensional scale measured a combination of different microskills in this part. This feature indicates that these single dimensional scales are basic single dimensional scales and non strict single dimensional scales, regardless of c value of 0.3 or 0.2. The basic single dimensional scale was selected to meet the requirements of weak monotonicity, and there was no significant difference in the differentiation function of the whole single dimensional scale.

【正文快照】： 考生在大规模教育考试中的行为一般受到多种潜质控制,如在数学考试中,考生的行为既取决于考生对数学知识的掌握程度,又取决于考生逻辑推理能力。又如考生在英语阅读考试中的表现既受到考生词汇量和阅读内容类型的影响,又受到考生的微技能的影响,如理解事实性内容的能力、理解
