Research On The National Mathematics (Science) Papers Of College Entrance Examination From 2018 To 2020

Mathematics,a basic subject,hold an key position in China's college entrance examination.The 19 th National Congress of CPC,show that "China will establish a new college entrance examination system by 2020".Similarly,we changed the math course criterion,which will guide our reform in recent years.Now,more regions have used the national examination paper,so,the study is going to analysis these paper in the past three years to grasp the law and trend of the proposition and promote mathematics teaching in high school.This study use literature research,contrastive research and data analysis method.By putting related material in order,this study regard " Common High School Math Curriculum Standards(2017 Edition 2020 Revision)" and " China College Entrance Examination Appraisal System" as theory.With the view of "what to test" and "how to test",this study builds a trinity framework to study the test content,requirements and carriers of mathematics in 2018-2020 National College Entrance Examination Mathematics(Science).The study show that:(1)Three-year National Mathematics Examination(Science)has obvious common characteristics.The number of questions in the 9 papers is same.There are multiple choice,blank and answer questions,and the ratio of each kind is constant.In terms of content,mathematical operation,logical reasoning and intuitive imagination accomplishment is higher than others,these focus on knowledge transfer level,knowledge innovation and knowledge understanding level is weak;On test requirements,9 papers are foundational,comprehensive second,application and innovation are low;About carrier,mathematical situation carrier is used most,scientific situation and reality situation is less.(2)The longitudinal comparison of Three-year National Mathematics Examination(Science)shows some change.In terms of content,logical reasoning and visual imagination literacy showed an upward trend,while the rest literacy decreased to varying degrees.The tests of knowledge understanding level decreased year by year.On test requirements,from 2018 to 2020,basic test requirements have a downward trend,but the comprehensive,application and innovation have different degrees of rise;About carrier,realistic situation is increasing year by year,and the mathematical situation and scientific situation are stable.(3)The horizontal comparison of Three-year National Mathematics Examination(Science)also have differences.Specifically,each accomplishment of knowledge migration level in National Volume I is high,stressing integrity and innovation,scientific situation is serious;National Volume II emphasis knowledge innovation level,highlighting applied examination requirements,realistic and mathematics situation are more;National Volume III,focus on knowledge understanding level,emphasize basic,carrier using the degree of the situation in the middle.Based on above conclusions,this research study that new questions can be added,reduce arithmetic,lay stress on the transfer and innovation of knowledge,redouble the check of usage and creativity,create reality and science situations.Suggest teachers try their best to foster students' math core literacy,raise knowledge transfer level,and use situation to highlight math value.
