新高考数学"三角函数"命题特点探究OA

Taking the 10 sets of new college entrance examination mathematics test papers from 2021 to 2025 as empirical samples,this paper systematically analyzes the proposition characteristics of the"trigonometric functions"test questions.Through data collection and quantitative statistics,this study focuses on examining the content distribution and score weighting of the test questions,the interconnected network of knowledge points and their frequency of examination,as well as the structural features of question-setting and the trends in proposition reform.The research indicates that the trigonometric functions module exhibits proposition characteristics marked by"the strongly interconnected network,high-level comprehensive assessment,and in-depth infiltration of mathematical competency".Within the knowledge network,knowledge points related to the properties of graphs and theorems serve as the main framework,while marginal knowledge points such as induction formulas are examined strategically.The proposition design follows a three-tiered gradient of"consolidating fundamentals,transferring methods,and applying innovations",promoting the development of higher-order thinking by setting multiple intersections of knowledge.Therefore,it is advisable to construct a knowledge network system to solidify foundational knowledge,break down barriers between knowledge modules to facilitate integration,infiltrate mathematical thinking to enhance abilities,and implement mathematical competency cultivation to promote all-round development in practical teaching.
