Analysis And Research On Mathematics Test Paper Of College Entrance Examination Based On SPSS Software ——Take National Science Volume Ⅱ From 2017 To 2021 As An Example

In this paper,the national college entrance examination（science）mathematics II volume in 2017-2021 is taken as the research object,which is mainly analyzed from four parts.In the whole part of the paper,the question type,the amount of questions,the proportion of scores and the test sites are analyzed.In the difficulty part of the test paper,this paper establishes a new comprehensive difficulty model,and uses SPSS software to make the relevant change trend chart of each level;In the part of mathematical thought and method,the college entrance examination papers are analyzed from the aspects of embodiment type,embodiment form,embodiment way and embodiment degree.In the "Series" section of the test center,this paper classified the related topics and summarized the solution strategies.The most important thing is to use SPSS software to make correlation analysis for each part.The main conclusions are as follows:From the whole test paper,there are some changes in the examination of fill-in-theblank questions.Judging from the difficulty of examination papers,the comprehensive difficulty coefficients from high to low are character level,reasoning level,operation level,thinking level,inquiry level,knowledge level and background level.From the perspective of thinking methods,These papers are mainly examine the functions and equations,the combination of numbers and shapes,and the thoughts of transformation and reduction.These papers are then examine the thoughts of classification and integration,probability and necessity,and the special and general thoughts are the least examined.From the "series" of test sites,we mainly examine four categories: finding the general term and the sum of the first n terms of the series,proving that it is arithmetic or geometric progression,and examining the series by using the nature of functions.From the perspective of correlation,the closer the year is to the knowledge point,the more significant the correlation is.The comprehensive difficulty coefficient of the last four years’ papers is more relevant.The frequency and average number of questions of mathematical thinking and methods are significantly related.Although the series is the test center of college entrance examination every year,the content of each year questions about its examination does not necessarily have continuous correlation.Based on the research conclusions,we propose the following suggestions: Suggestions on the simulation exercise: Expand the background check and Closely connect with life;Reasonable knowledge coverage and Proper structure adjustment;Pay attention to ideological examination and Adjust the difficulty level.Teachers’ teaching suggestions:Pay attention to the examination policy and Grasp the college entrance examination questions;Attach importance to teaching material research and Consolidate knowledge system;Reflect the students’ main body and Presuppose classroom generation;Infiltrate thinking methods and Improve students’ abilities.Students’ learning strategies: Build a knowledge framework and Form a cognitive system;Carry out logical training and Summarize problem-solving strategies;Design preparation review and self-improvement.
