Investigation On The Data Analysis Literacy Level Of Senior High School Students

In the face of the massive information which comes one after anther in the information age,the processing and analysis of the data are increasing day by day.The General High School Mathematics Curriculum Standard(2017 Edition)also lists data analysis literacy as one of the six core mathematical literacy of high school students.The importance of data analysis literacy is self-evident.However what is the current situation of data analysis literacy of high school students? It is still a problem that makes the majority of teachers confused.Therefore,it is urgent to study the current situation of senior high school students' data analysis literacy.This research raises the core question: what is the status of data analysis literacy for high school students?The methods of contribution analysis,investigation and statistical analysis were adopted.First of all,based on the relevant research,this paper constructs a data analysis literacy evaluation framework for senior high school students,which includes three first level dimensions(awareness and perception of data,awareness and perception of methods,awareness and perception of randomness)and eight second level dimensions.Each dimension is divided into four levels according to the SOLO classification evaluation theory.Secondly,according to the evaluation framework,a test paper that examines the data analysis literacy level of high school students has been prepared.Then,a total of 225 high school students from three middle schools were selected as the survey objects.SPSS was used to analyze the data in a single dimension and related factors to draw conclusions.Finally,according to the results of the survey,this paper puts forward some suggestions on the cultivation of senior high school students' data analysis literacy.The following conclusions were reached based on the results of the study.From the overall level,high school students' data analysis literacy is generally at the multi-structural level(M)and normally distributed.From the first level dimension,senior high school students are lack of awareness and perception of data and methods,and grasp the randomness better than the first two dimensions.There is a statisticallysignificant difference in the overall level of literacy of senior high school students in the two related factors of "grade" and "school grade",but there is no significant difference in "gender".
