长春市与吉林省中考统计类试题的难度分析

The Difficulty Analysis of Statistics Questions in the High School Entrance Examination of Changchun City and Jilin Province

摘要: 基于2019~2023年长春市中考数学试卷与吉林省中考试卷共10道统计类试题，采用内容分析法对试题进行统计，采用鲍建生综合难度模型对试题难度进行对比分析。研究发现：长春市在“数学认知”、“推理”和“知识点”水平难度上高于吉林省，在“试题背景”和“运算”水平难度差距不大。结合教育部积极推进中考省级统一命题，建议吉林省中考统计类试题在“数学认知”、“推理”和“知识点”3个因素上提升试题难度，优化统计类试题的质量。
