Investigation And Research On The Status Of High School Students' Data Analysis Literacy

Data analysis literacy is included as one of the six mathematic core qualities in general high school mathematics curriculum standards(2017),which reflects the important role of data analysis literacy in the construction of mathematics disciplines and shows its important educational value.To implement the development requirements of students' core literacy in the information age,data analysis literacy is particularly important for the development of contemporary students.This paper focuses on the empirical research on the status of students' data analysis literacy under the statistical content.Based on the empirical research results,this paper aims to put forward targeted teaching suggestions for front-line statistical classes,which is beneficial to understand overall statistical knowledge with students' data analysis literacy for teachers.By collecting research literature about data analysis literacy,this paper studied and analyzed the way of constructing the data analysis literacy system and three level cases of data analysis literacy according to the mathematics curriculum standard of general high school(2017).At last,the test papers of data analysis literacy level and the questionnaire of cognitive attitude of data analysis literacy were prepared,and the students of senior two from the NO.4 High School of YanTai were selected as questionnaire objects.According to experimental results,we quantitatively analyzed the current level of students' data analysis literacy and their subjective cognition of data analysis literacy.The conclusions of data analysis literacy level research are as follows: High school students' data analysis literacy is at the lower middle level;Students' data analysis literacy level is similar in the four dimensions including of situation and problem dimension,data processing and Characterization dimension,data thinking and expression dimension,data communication and reflection dimension.Comparatively speaking,the scoring rate of data analysis literacy in data processing and representation dimensions is not optimistic.There was no significant gender difference in students' data analysis literacy.There are differences in students' data analysis literacy in traditional arts and sciences classes,and there is no significant difference between classes majored in physics,chemistry,biology and traditional classes under the 3+3 model.The conclusions of data analysis literacy awareness attitude are as follows: High school students have a good overall attitude towards data analysis literacy.There was no significant gender difference in the cognitive attitude of data analysis literacy.Under the 3+3 model,there is no significant difference in the cognitive attitude of students' data analysis literacy in the different classes.There is a correlation between students' data analysis literacy and their cognitive attitude towards data analysis literacyBased on the empirical survey results,it provides some inspiration for the statistical classroom with data analysis literacy and practical suggestions for the first-line teachers to implement statistical content.We should consolidate the concept of statistical foundation and pay attention to the dimensional horizontal performance of data processing.In the statistical teaching to carry out a variety of forms of statistical activities and balanced development of students' data analysis literacy in different classes.Statistical teaching does not take gender differences into account.Actively advocate the rational allocation of 3+3 model class resource structure.To cultivate students' awareness of positive cognitive attitude towards data analysis literacy.
