Research On Core Literacy Development And Cultivation Strategy Of Junior High School Students' Data Analysis

With the education community put more emphasis on the core literacy of mathematics,data analysis literacy has also become one of the core literacy of mathematics in the middle school mathematics curriculum standards.Through reading relevant literature,it is found that the core literacy education of data analysis in China is not ideal.Most schools despise the cultivation of core literacy of Students' data analysis,and the relevant teaching content is separated from the needs of students' actual life.Therefore,how to carry out data analysis education for junior high school students,cultivate students' data analysis ability and improve their literacy level has become a hot spot in basic education research.Although there is much research literature on the core literacy of data analysis,the previous research on the core literacy of data analysis mainly stayed on the related conceptual research and educational theory,and Few is about students' actual data analysis ability and development.It is necessary to explore the status and differences of the data analysis core literacy development of junior high school students.Starting from the development level of data analysis ability of students,the research explores the current situation and differences of data analysis core literacy development of junior high school students through investigation and research methods,and puts forward corresponding training strategies.The study found that the student's perceptual ability on data increases with grades;students' language ability in analyzing and interpreting data is poor;students 'ability practical to actively collect data is not ideal;and students' ability to predict data is at a relatively low level.In addition,there is a gap between the textbook statistics and probability content of teaching materials and the cultivation requirements of data analysis literacy.Teachers rarely use real-life examples to explain knowledge.Teachers ignore the cultivation of students 'practical ability in actual teaching.The evaluation mode of students' data analysis literacy in schools is not reasonable.According to the data analysis of junior high school students' core literacy survey results and related literature research,the following training strategies are proposed: Strengthen the teaching and the training of data analysis language to improve the ability to express data analysis results;Appropriately enrich the teaching content or reverse the teaching concept to connect data analysis literacy Training requirements;Enrich more real-life examples in teaching to increase the interest in data analysis-related content;Increase the proportion of statistical probabilistic practice assignments to enhance the awareness of applied data analysis literacy;Set up some appropriate micro courses about data analysis technology to improve data analysis literacy.The research lays a certain research foundation for the cultivation and development of the core literacy of data analysis of basic education in China,and provides strategies and methods with certain reference value for the training of the data analysis ability of junior high school students.
