The Evolution Of The Structure And Content Of The Three-dimensional Geometry Test Questions In The College Entrance Examination

The college entrance examination is the most important summative evaluation in high school student mathematics.It is based on mathematics curriculum standards to evaluate the quality of academic quality.The college entrance examination mathematics test is to test the achievement of mathematics core literacy in mathematics learning,and analysis of college entrance examination questions can help teachers grasp the breadth and depth of teaching,promote the reform of mathematics courses,and improve teaching evaluation mechanisms to jointly promote the reform and innovation of talent training model.The solid geometry test questions can examine students’ intuitive imagination,logical reasoning and calculation skills,and therefore become an indispensable part of the college entrance examination national volume.This article has passed the national paper(science mathematics)for a total of 43 years since the resumption of the college entrance examination from 1978 to 2020.In the solid geometry test questions to analyze the changes in its structure and content.The study of solid geometry test question structure is divided into three aspects:question type,question volume,score and ratio;the study of solid geometry test question content is divided into four aspects:assessment knowledge points,reading volume,graphic model,and comprehensive difficulty.Through collating and analyzing relevant specific data,the following research conclusions are obtained.Structure evolution of college entrance examination mathematics solid geometry test questions:l.The assessment has a wide range of question types,including multiple-choice questions,fill-in-the-blank questions and answer questions.Where the choice questions are the most,the assessment in the blanking problem is less,and the assessment is relatively stable in the solution question,especially the test questions every year in the test paper.2.The amount of test paper assessment in the past years fluctuated steadily,and the amount of different years is 3.42,and the assessment frequency is relatively high.3.The value of the entire volume is large,and the late stage tends to stabilize.The proportion of the entire volume is stable.The average mean and proportional mean of the solid geometric test questions in different years are 22.14 and 16%,respectively,and the assessment is relatively large.Content evolution of college entrance examination mathematics solid geometry test questions:1.The key assessment knowledge points remain stable,and less intensive points with other parties.2.The reading amount will be described by the number of characters.All the average characters of all test questions are 63,and the average characters of each subject are small.The reading is relatively balanced.The solid geometry questions focus on the assessment of the conversion ability between symbolic language,graphic language and text language.3.The abstract mathematical pattern model is generally given directly to the assessment graphics model,which is less in combination with the physical model,with cones appearing the most frequently.4.According to the comprehensive difficulty coefficient model:the mean value of the comprehensive difficulty coefficient is 14.37,for mathematical calculation capacity,logic reasoning ability assessment is relatively stable;expand thinking space by means of spatial graphic,solve calculation or proof;gradually pay attention to the solid geometric comprehensive investigation of the problem,the exploratory problem setting is less.On the basis of the above-mentioned research conclusions,teaching recommendations:based on teaching materials,focus on space parallel and vertical relations;based on the foundation,master the solid geometric connectivity access method;based on the classroom,pay attention to intuitive perception and speculative argument;development literacy,arrange the reasoning training step by step.In propositions,a diversified test situation should be set,add open problems and avoid a single proposition method,and make more combination points in the intersection of knowledge.Hoping the research of this paper to provide some help for classroom teaching and examination questions.
