| The analysis of college entrance examination mathematics paper is one of the most important links in high school mathematics teaching,through the analysis of the test paper can not only obtain the characteristics of the high school examination questions,but also provide guidance for the later teaching of front-line teachers.At present,the way of qualitative analysis of test papers by front-line teachers is mainly to judge the difficulty of test papers by analyzing the content of the examination and solving the questions,which relies too much on the teaching experience of teachers.The quantitative analysis paper is usually based on the classical measurement theory,but the theory has shortcomings in theoretical assumptions and mathematical model construction,and teachers cannot fully grasp the real learning situation of students.In contrast,project response theory makes up for the shortcomings of classical measurement theory in terms of theoretical assumptions and theoretical models,so this study selects project response theory as the theoretical basis to analyze the college entrance examination mathematics paper.This paper takes the project reaction theory as the theoretical basis to study the propositional characteristics of the college entrance examination stereometric test paper.Firstly adopts the literature research method to collect and analyze the research status of the project response theory and the college entrance examination mathematics stereo geometry test questions;Secondly,according to the standard requirements of the stereo geometry course and the content of the textbook,the examination content of the three-dimensional geometry part of the college entrance examination mathematics was collected,and then combined with the students participating in the test and the suggestions of front-line teachers,the test paper was reorganized to implement the test;Then,the theoretical model is determined according to the characteristics of the questions,specifically,the three-parameter logical St model(3PL)is selected to analyze the multiple-choice questions and fill-in-the-blank questions,and the generalized division scoring model(GPCM)is selected to analyze the solution questions.Finally,with the help of software,the guessing parameters of multiple-choice questions and fill-in-the-blank questions are estimated,and the difficulty parameters,discrimination parameters,project characteristic curves,project information curves and the ability values of each student are estimated for each question.Through the analysis of the parameters of the test questions and the students’ ability values,it is concluded that the college entrance examination mathematics three-dimensional geometry test questions have the following characteristics:(1)the question parameters meet the requirements of the exam;(2)the difficulty parameter has a trend of increasing year by year;(3)the student ability value is roughly normally distributed.Finally,based on the above research results,the propositions of stereometric geometry questions and teacher teaching in the college entrance examination are given,and the shortcomings and prospects of the research are pointed out. |
