| The concept of data analysis plays an important role in the core literacy of mathematics.In order to meet the development needs of the era of big data,compulsory education pays more and more attention to cultivating students’ data analysis ability.Statistics and probability are the knowledge carriers to cultivate students’ concept of data analysis.The Mathematics Curriculum Standard for Compulsory Education(2022Edition)has enhanced the attention of related contents and increased the knowledge of statistics and probability modules.Based on the requirements of the curriculum standard for the concept of data analysis,and aiming at cultivating students’ concept of data analysis with high quality in local junior middle school mathematics education,this paper launches the following three aspects of research:(1)Constructing an evaluation framework for the development of junior middle school students’ concept of data analysis in Lhasa;(2)Analyze the current situation of the development level of data analysis concept of junior middle school students in Lhasa;(3)Designing a lecture note model of "Read,Think,Deliver" based on the concept of data analysis,which provides a theoretical basis for cultivating the development level of junior middle school students’ concept of data analysis in Lhasa.This paper selects two representative junior middle schools in Lhasa and its suburbs as research objects,Based on the contents of statistics and probability in textbooks used by junior middle school in Lhasa,as well as the statistical data of related documents and yearbooks,this paper designs an evaluation framework for the development level of junior middle school students’ data analysis concept in Lhasa from three dimensions:data awareness,data analysis methods and data randomness;On this basis,the test paper and questionnaire are compiled,and the current situation of the development level of data analysis concept of junior middle school students in Lhasa is studied in deepth;Finally,from the perspective of the connotation of core literacy,that is,"three must",combined with the research results we obtained,the teaching case of " Read,Think,Deliver " of junior middle school students’ data analysis concept is made,which can be used as a reference for the statistic teaching. |
