The Investigation On The Literacy Of Data Analysis Of Junior Students

With the rapid development of computer science and information science and the rapid development of the Internet,our life is filled with the network data.Under this situation,it is necessary for people to master the techniques and methods of extracting valuable information from data,that is to say,people should have data analysis literacy.In the 2017 version of the high school mathematics curriculum standard,data analysis is included in mathematics core literacy.However,Compared with the emphasis on data analysis in real life and mathematics curriculum standards,the cultivation of students' data analysis literacy in practical teaching is insufficient.In this context,it is necessary to carry out actual investigation and research on the status for data analysis literacy high school students in China.After analyzing and summarizing the previous studies of mathematics core literacy data and data analysis literacy accomplishment and combining the research question.Data analysis literacy's assessment framework is established and a test is designed.A high school in Jinzhou city grade 11 students are measured.At the same time,samples are collected from the students and teachers of the school.There are the two aspects of teachers and students to understand the current situation of data analysis literacy of senior two students.The survey results show that:1.The data analysis literacy of senior two students generally performed well,but there were still problems in all dimensions.2.In the “mathematical process”dimension,students lose information easily in “mathematical expression” and hinder the solution of problems;In “the use of mathematics”,more incline to use the familiar methods(experience)to solve the problem;In “mathematical interpretation”,few students can fully “explain”.3.In the dimension of "data analysis",some students are not able to use the sampling method flexibly,which can easily confuse the correlation and function relationship.In the sample estimation,the students can get the correct inference.4.In the “reality situation” dimension,students' performance under different realistic situations is no obvious difference.After understanding the status of data analysis literacy of senior two students,the following suggestions are put forward for the teaching of teachers:1.In the course of teaching,reflect and evaluate the problems according to the actual content.Exercise students to improve their data analysis literacy in reflection.2.The teachers improve their own quality,accumulate statistical practice material and choose suitable activities for students in the process of statistics teaching practice to make students “learning by doing”to improve students' literacy in data analysis.3.Make use of students' existing experience to enhance students' understanding of the essence of the concept of sampling method so that students can collect reasonable and representative data when solving statistical problems.4.In the statistics course,computer demonstration teaching is used to enable students to get close to data and learn data analysis methods in a relaxing and interesting environment,thus improving data analysis literacy.
