A Comparative Study Of Math And Science Questions In The College Entrance Examinatio

The development of college entrance examination papers has been closely related to the reform of college entrance examination papers,and the difficulty of college entrance examination papers is a hot topic of the whole society.In recent years,the reform of national college entrance examination has been deepening.Taking Sichuan as an example,the reform of college entrance examination began to be implemented in2022,and the new high school examination papers will be used in 2025 instead of the national examination papers In order to better apply the reform of the new college entrance examination,it is necessary to compare and analyze the mathematics questions of the national examination paper and the new college entrance examination paper from the aspects of the differences in examination content and difficulty.Therefore,this paper uses the difficulty comprehensive model for the recent three years of the national A examination paper and the new college entrance examination This paper analyzes and compares the differences between the two,helps front-line teachers quickly adapt to education work,and provides effective learning suggestions for student.Based on the integration and sorting of the contents of the recent three years of mathematics college entrance examination papers,this paper firstly compares the contents of the papers horizontally and vertically according to different knowledge units,and analyzes the proportion of the national A paper and the new college entrance examination papers in different knowledge units.Secondly,combined with the comprehensive model of difficulty,the paper analyzes the distribution and changing trend of the questions in different levels of difficulty factors in recent three years.Finally,by comparing the difficulty values of each difficulty factor.the chart is drawn and the main conclusions are as follows:(1)The length of the examination,the number of questions in the examination paper and the total score remain relatively stable,but the two sets of examination papers are different in the question type and content distribution.In terms of question types,the national paper A questions include single-choice questions,fill-in-the-blank questions,required questions and optional questions;The new examination paper Ⅰincludes single-choice questions,multiple-choice questions,fill-in-the-blank questions and conciliation questions.From the perspective of content analysis,the knowledge points of National A paper and the new college entrance examination Ⅰ paper cover a wide range,but their emphases are different.From the perspective of knowledge unit analysis,the new college entrance examination Ⅰ paper is more powerful than the national A paper in the four knowledge blocks of inequality,trigonometry,series and counting principle,and in the three knowledge units of solid geometry,analytic geometry,probability and statistics.The strength of the national Grade A examination is far greater than that of the new college entrance examination Ⅰ examination.(2)From the analysis of the proportion of questions in the seven difficulty factors,there are differences in the proportion of questions in different levels of each factor in the two sets of papers.The new college entrance examination paper occupies a higher proportion than the national paper A in the level of public common sense simple symbol operation complex numerical operation complex reasoning complex reasoning2 knowledge units reverse thinking comprehension.In the background of personal life science,the questions of reference level,simple reasoning,multiple knowledge unit analysis and other levels accounted for the same proportion of the two sets of paper(3)From the difference analysis of comprehensive difficulty,the difficulty of the new college entrance examination Ⅰ paper is higher than that of the national Grade A paper.In terms of reference factors,the difficulty value of the national A-paper is 1.52,and that of the new college entrance Examination Ⅰ paper is 1.53.Therefore,there is no difference in the difficulty of reference factors between the two.In terms of background,thinking direction,cognitive level,reasoning ability,knowledge content and other factors,the difficulty of the new college entrance examination Ⅰ paper is significantly higher than that of the national A paper.In terms of calculation ability and other factors,the difficulty coefficient of the national A-test is greater than that of The new college Entrance Examination Ⅰ.
