| Under the background of quality education,teachers should pay attention to the cultivation of students’accomplishment,only in this way can students better meet the requirements of the development of The Times for talent cultivation,and mathematics curriculum reform can continue to develop deeply.In order to achieve the goal of"promoting teaching by evaluation",improve the level of primary school students’mathematical literacy,improve the teaching practice of mathematics curriculum content and students’academic evaluation,this study constructed the evaluation model of primary school students’mathematical literacy,in order to put forward some scientific and effective suggestions for the development of students’mathematical literacy.Primary school is an important period of formation and development of students’mathematics accomplishment,therefore,research on elementary mathematics accomplishment evaluation index system has very important practical significance,it can not only enrich education measurement and evaluation of relevant theory,also help students better grasp mathematics knowledge and improve mathematical language expression ability and problem solving ability.This study refers to the construction ideas of various existing educational evaluation index systems and evaluation models in China,and then according to the construction paradigm of educational evaluation models in the era of big data,Using literature analysis method,text analysis method,Delphi method,test survey method,analytic hierarchy process,descriptive statistics method,difference analysis method,correlation analysis method,factor analysis method,and verification factor method and other qualitative and quantitative methods,to explore the construction of elementary school students’mathematical literacy evaluation model.In addition,the primary school students’mathematical literacy test papers were prepared to verify and initially apply the evaluation model.The specific research contents and conclusions are as follows:Firstly,explore the operational definition of primary school students’mathematical literacy.Through literature review,analysis of curriculum standards and textbooks,as well as expert consultation,this study clarifies the connotation and behavior of primary school students’mathematical literacy,and tries to determine the operational definition of primary school students’mathematical literacy:（1）to recognize things in real life from the perspective of mathematics;（2）Use mathematical language and principles to describe and express practical problems;（3）Analyze problems with mathematical concepts,facts and procedures;（4）Use mathematical concepts,facts,ideas and methods to solve problems in different situations.Secondly,determine the primary school students’mathematical literacy evaluation index system.First of all,according to the operational definition of primary school students’mathematical literacy and the principle of index system construction,combined with the theoretical research on the connotation of mathematical literacy in the early stage,the primary and secondary indicators of the evaluation index system of primary school students’mathematical literacy are preliminarily drawn up.Then,through the Delphi method of collecting and analyzing expert opinions and re-reading of relevant literature,the evaluation indicators are revised,and the evaluation indicator system of primary school students’mathematical literacy is finally established,including 3 first-level dimensions and 11second-level indicators,among which 3 first-level dimensions are:Mathematical understanding（to understand things in practical problems from the perspective of mathematics）,mathematical expression（to describe and express practical problems with mathematical language）,mathematical application（to solve problems in different situations with mathematical concepts,facts,ideas and methods）.Thirdly,establish the evaluation model of primary school students’mathematical literacy.Firstly,according to the constructed evaluation index system of primary school students’mathematical literacy,a questionnaire was prepared to judge the relative importance of indicators at the same level,and an expert survey was conducted.The weight of indicators at all levels was determined through analytic hierarchy process（AHP）,and then the evaluation model of primary school students’mathematical literacy was obtained:Y=0.23X1+0.25X2+0.52X3,where X1 represents mathematical cognition,X2represents mathematical expression,and X3 represents mathematical application.Fourthly,verify and apply the primary school students’mathematical literacy assessment model.In this paper,we use the test survey method to verify and apply the mathematical literacy evaluation model,and select the fifth grade primary school students in Sichuan and Chongqing area as test objects.According to the evaluation index system,the test paper is prepared,and the corresponding quality analysis of the test tool is carried out,which proves that the difficulty and differentiation of the test paper are reasonable,and it has high reliability and good validity.Then,analysis the development situation of elementary school students maths,and the subjects of maths performance in both gender and urban and rural difference analysis,a series of analysis results conform to the actual situation,this study built elementary mathematics evaluation model has certain operability and effectiveness.To sum up,this study elementary mathematics evaluation model is established for the first time,and the corresponding evaluation model validation and the simple application,including the research lies in the primary school mathematics accomplishment evaluation index system of building as well as the development of measurement tools,but because the research time is limited,and the limitation of research conditions,this study of sample size and sample representativeness existing deficiencies,Future research needs to be supplemented and improved in the reliability and validity of the evaluation indicators and measurement tools. |
