摘要
高考是选拔性考试,强调对考生的精确区分,研究试卷的区分功能有助于科学评价试卷的区分效果,进而提高试卷的区分能力。试卷的区分功能可以用标准差的临界值、变异系数等统计学方法进行评价,也可参照试题区分度的评价方法,应用相关系数法和极端分组法进行评价。
As discriminating power is critical for the College Entrance Examination(CEE) to accurately distinguish students of different achievement levels, relevant research helps to scientifically evaluate and improve the discriminating power of the CEE. To that end, statistical indicators such as the critical value and the coefficient of variation can be used to evaluate the discriminating power of the CEE. Moreover, methods used to estimate the discriminating power of test items, such as the correlation coefficient and extreme groups, can also be used to calculate the discriminating power of the entire examination paper.
