Analysis Of Probability And Statistics Test Questions And Teaching Strategies Of College Entrance Examination Mathematics From The Perspective Of Core Literacy

With the deepening of the curriculum reform of basic education and the promulgation of the Curriculum Standard of ordinary high school Mathematics(2017 edition).The examination form of higher examination items has changed from the traditional examination of arts and sciences(hereinafter referred to as the traditional college entrance examination)to the new non-examination of arts and sciences(hereinafter referred to as the new college entrance examination),and the examination content is more prominent in the examination of core literacy.Taking the "probability and statistics" module of college entrance examination in recent ten years as an example,this paper analyzes the question types,knowledge points and the frequency of examination of core literacy from the perspective of core literacy.By coding analysis and comparative research,this paper studies the difficulty of "Probability and statistics" module from seven elements:background,reference,operation,reasoning,knowledge,thinking and cognition.Students and teachers are investigated by means of questionnaire and interview,and corresponding teaching strategies are proposed from the perspective of core literacy.The analysis and investigation results show that the "probability and statistics" module has little change in the type of questions and comprehensive examination of knowledge points.Compared with the traditional college entrance examination,the new college entrance examination not only tests students’ grasp of basic knowledge,but also focuses on testing students’ ability to obtain effective information in the question stem,comprehensive use of knowledge,complex symbol operation and logical reasoning.From the perspective of core literacy,core literacy test changes slightly,among which the most tested are mathematical operations and logical reasoning.This requires teachers to train students’ computational ability consciously and purposefully in teaching,and inspire students to think,reason and demonstrate relevant problems,so that students can effectively explore ways to solve problems in complex formulas,theorems and question types,so that students can better understand,grasp and apply knowledge.
