Study On Comprehensive Evaluation Of Mathematical Modeling Activities Of Senior High School Students

After mathematical modeling has been established as the core accomplishment of mathematics,mathematical modeling has gradually become one of the central topics of mathematics education,and the evaluation research of mathematical modeling has also gradually become one of the hot topics of educational evaluation.More and more middle schools begin to carry out mathematical modeling activities to cultivate students' mathematical modeling literacy.However,at present,the relevant research on how to evaluate mathematical modeling activities is not sufficient and lacks a scientific evaluation system,which mainly relies on the subjective judgment of judges.Based on the above reasons,the research problem of this paper is determined--how to evaluate the mathematical modeling activities of senior high school students.Firstly,the related concepts of mathematical modeling are reviewed and the research status of mathematical modeling evaluation is summarized.Then through the analysis of the existing research,combined with the author's on-the-spot research experience,extracted the evaluation index of high school students mathematical modeling activities,and combined with the case to illustrate each index,summed up the evaluation basis table of mathematical modeling activities evaluation index.Secondly discusses the evaluation principles that should be followed in the process of evaluation,introduces fuzzy comprehensive evaluation method and sequence diagram method,the questionnaire survey to experience mathematical modeling of teachers to the importance of the each evaluation index,calculating the average scores of each evaluation index,the optimal sequence diagram method are used to determine the weight of each evaluation index,build the evaluation index system.Finally,based on the evaluation index system constructed in this paper,the fuzzy comprehensive evaluation method was used to comprehensively evaluate the students' mathematical modeling activities,and the ICC intra-group correlation coefficient method was used to verify the consistency of the evaluation results.Through the research of this paper,the evaluation indexes of high school students' mathematical modeling activities are obtained: Topics selection,knowledge application,data analysis,use of computer tools,paper writing,defense performance,model innovation,scientific spirit,team cooperation,and calculate the weight of each index,the order is 0.0494,0.1235,0.2099,0.1235,0.1605,0.0124,0.0864,0.0494,0.1852.
