Analysis Of Conic Curve Questions In College Entrance Examination From The Perspective Of Mathematical Operational Literacy

As one of the six core literate family members,“mathematical operation”not only has a great positive impact on the formation of other core literacy,but also plays a key role in the learning process of other disciplines.The research is in line with the development trend of mathematics education.The mathematics test of the college entrance examination is a test tool for evaluating the development level of students' core literacy.In the mathematics test of college entrance examination,using the conic curve as the background to test the test questions,we can do an irreplaceable examination of the students' mathematical computing ability.It can be said that the college entrance examination conic curve test questions are good for cultivating students' core literacy of “mathematical operations” material.Therefore,the author believes that it is necessary to study the situation of the core level of “mathematical operations” in the conical curve test of the college entrance examination over the years.Based on the literature review,this study established the 2011-2018 National Volume I college entrance examination mathematics conic curve test questions as the research object,mainly using comparative analysis method and statistical analysis method for the eight-year conic curve test questions.The difficulty level of the core literacy examination of mathematical operations is studied.This study uses the “study quality level” proposed by the new curriculum standard as a research tool to construct an analytical framework for the core literacy of “mathematical operations”.The framework mainly includes situations and problems,knowledge and skills,thinking and expression,communication and reflection.Dimensions,each of which contains three levels.A detailed comparative analysis of the core literacy examination level of “mathematical operations” in the eight-year college entrance examination conic curve test questions.This study uses Bao Jiansheng's comprehensive difficulty model to quantitatively analyze the college entrance examination conic curve test questions,in order to support the previous research results of the “mathematical operation”core literacy test difficulty level in the test questions.The following conclusions are drawn:(1)Simplification of test situation settingFrom the perspective of situation and problem,the college entrance examination coniccurve test questions are straightforward in the pure mathematics situation,and need to solve the mathematical problems that need to be solved.There is no real life situation,scientific activity situation,and the conic curve test questions are set in the test situation.It is singular.(2)Test questions to examine diversityFrom the perspective of knowledge examination,the college entrance examination conic curve test is not only to examine the conic curve knowledge,but to combine the conic curve knowledge with the knowledge points of vector,derivative,inequality and so on.It can be seen that the examination of the conical curve test questions of the college entrance examination is Diversified.(3)The test literacy difficulty set level one and level two in oneJudging from the dimension of the difficulty level of literacy examination,the level of the core literacy of the propositional difficulty set of the college entrance examination conical curve test is one level and one level.In view of this,this study combines relevant educational theories and proposes the following teaching suggestions for the content of the conical curve of the college entrance examination: based on the “four basics” teaching,training students “four energies”;focusing on the integration of conic curve knowledge and other knowledge points of mathematics Teaching;attach importance to the integration of information technology and teaching.Finally,this study refers to the relevant spirit of the new curriculum standards,and puts forward the following suggestions for the proposition of the college entrance examination conic curve test:attach importance to the examination of background factors,create flexible problem situations;grasp the calculation of the times,grasp the comprehensive difficulty of the test questions;set up open questions to enhance students' awareness of inquiry and innovation.
