新高考数学试卷绝对难度的研究——以2021年新高考数学全国Ⅰ、Ⅱ卷为例

Research on the absolute difficulty of the new college entrance examination mathematics paper——Take 2021national college entrance examination I and II as an example

2021年采用新高考数学全国卷的省份增加至10个,其难度和区分度受到广泛关注.本研究基于SOLO分类评价理论,将试题绝对难度细分为13个水平,探究了2021年新高考数学全国Ⅰ、Ⅱ卷的绝对难度及区分度.结果表明两份试卷绝对难度基本相同,区分度均良好,能够很好地检测不同水平学生之间的差异.但是考查的侧重点有所不同:新高考Ⅰ卷较注重绝对难度为多重结构水平、关联结构水平、拓展抽象水平的考查,新高考Ⅱ卷较注重绝对难度为多重结构水平和拓展抽象水平的考查.

In 2021,the number of provinces adopting the new national college entrance examination mathematics paper has increased to 10,and its difficulty and differentiation have attracted wide attention.Based on the SOLO classification evaluation theory,the absolute difficulty of the test is subdivided into 13 levels,and the absolute difficulty and differentiation of the 2021new college entrance examination inⅠ,Ⅱis explored.The results show that the absolute difficulty of the two papers is basically the same,the differentiation is good,can well detect the difference between different levels of students.
