基于综合难度系数模型的高考试题评价研究——以2020~2022年数学新高考I卷为例

Research on the Evaluation of College Entrance Examination Items Based on the Comprehensive Difficulty Coefficient Model—A Case Study of the New Math College Entrance Examination I from 2020 to 2022

摘要: 试题难度是反应试题质量的重要指标，文章基于综合难度系数模型，以2020至2022年三套数学新高考I卷为研究对象，从背景因素、是否含参、运算水平、推理能力、知识含量、思维方向、认知水平7个维度进行难度分析，发现3套试卷难度逐年增加。试题呈现情境化、基础性、综合性、创新性等特点，在此基础上对中学数学教师提出建议：创设现实情境，开展教学活动；摒弃题海战术，重视知识本质；开展单元教学，构建知识体系。

Abstract: The difficulty of test items is an important index reflecting the quality of test items. Based on the comprehensive difficulty coefficient model, this paper takes the three sets of new mathematics college entrance examination I paper from 2020 to 2022 as the research object, from the background factors, whether to include parameters, calculation level, reasoning ability, knowledge content, thinking direction, cognitive level to carry out difficulty analysis, and found that the difficulty of the three sets of papers increased year by year. The questions present the characteristics of situationization, foundation, comprehensiveness and innovation. On this basis, some suggestions are put forward for middle school mathematics teachers: create realistic situation and carry out teaching activities; abandon the tactics of the sea of questions, pay attention to the essence of knowledge; carry out unit teaching and build knowledge system.
