Core Literacy Oriented Mathematics And Comprehensive Difficulty Analysis Of Middle School Entrance Examination ——Taking The Mathematics Test Questions Of Middle School Entrance Examination In Xining City In Recent Five Years As An

Core mathematics literacy is in the process of the students in the corresponding period,and gradually form the necessary to adapt to individual lifelong development and social development of mathematical character and key ability,mathematics is a reflection of students’ mathematics education ultimate goal,the students can see the real world from the view of mathematics,using mathematical language to express the real world,will be thinking in mathematical thinking in the real world.Based on structural analysis and guided by core literacy,this study constructs the evaluation framework index system of mathematics core literacy and comprehensive difficulty evaluation framework index system to analyze and study the questions in xining City from 2017 to 2021.The conclusions are as follows:1.The common characteristics of xining high school entrance examination mathematics questions are obvious,the question types remain stable,including multiple choice questions,fill-in-the-blank questions and solutions,and the scores of various types of questions remain basically stable.2.The test questions focus on the examination of core literacy.The proportions of each core literacy are: 32.50% of computing ability literacy,15.25% of geometric intuition literacy,17.17% of reasoning ability literacy,6.83% of data analysis concept literacy,10.00% of abstract ability literacy,and 5.25% of model concept literacy The proportion of space concept literacy was 4.50%.3.From the level indicators of core literacy,the proportion of level 2（knowledge transfer）test questions is 58.42%,the proportion of level 1（knowledge understanding）is 22.00%,and the proportion of level 3（knowledge innovation）is 18.42%.4.Xining high school mathematics test questions comprehensive difficulty overall difference is not obvious.They all tended to examine the combined difficulty of "operation," "reasoning," "mathematical cognition," and "intuitive imagination." However,the combined difficulty of "background","knowledge" and "data analysis" needs to be paid more attention.5.From the perspective of core literacy orientation,the core literacy of mathematical operation,logical reasoning and geometric intuition of mathematics test questions in Xining middle school entrance examination accounts for a large proportion,and the related comprehensive difficulty of "operation","reasoning" and "intuitive imagination" in the difficulty model is also large;The proportion of core literacy of data analysis is small,and the corresponding indicators of comprehensive difficulty of "data analysis" are also small.6.The core literacy indicators,comprehensive difficulty indicators,and the overall core literacy and comprehensive difficulty of the test paper are continuous and stable.
