Mathematics Discipline Ability Evaluation Based On PISA

This paper constructs a mathematical subject ability evaluation model based on the PISA concept,conducts data based on PISA mathematics test and mathematical subject ability questionnaire survey for junior middle school students in xining city,the computer software SPSS20.0 to conduct correlation,principal component and linear regression analysis of the original data.The performance of the subjects in 8dimensions of mathematical ability was analyzed;The correlation between test scores and mathematical ability in 8 dimensions is analyzed.The regression equation of the main variables is fitted.The fuzzy comprehensive evaluation of mathematics subject ability of grade 9students in xining city shows that the overall level of mathematics subject ability is in the middle level.At the same time,this paper also gives the evaluation model of individual mathematics subject ability.The innovation of this paper lies in :(1)learning from the design concept of PISA test,and with the help of expert teachers,subject experts and teachers from xining municipal institute of education and science,the paper has been repeatedly revised and made into a comprehensive and reasonably difficult test paper.The test item went through "proposition discussion-sample test paper-sample test and analysis-part test-sample paper change-formal test"(2)combined the mathematical performance based on PISA with eight dimensions of mathematical ability,and constructed the evaluation index and evaluation model of mathematical subject ability.
