Research On Strategies For Improving Middle School Students' Data Analysis Literacy From The Perspective Of Basic Mathematics Activity Experience

Data analysis has become the core content of discussion and research in today's era.In the era of big data,there is a great demand for the training of talents with data analysis literacy.Modern mathematics teaching pays more attention to the accumulation of students' experience of basic mathematics activities,but the research on applying the experience of basic mathematics activities in teaching design and practical operation is still very scarce.Probability and statistics teaching contains a large number of mathematical activities,which is very suitable for carrying out related activity courses to improve the data analysis literacy of middle school students.In order to improve the data analysis literacy of junior high school students,the main task of this paper is to clarify the training strategies of data analysis literacy.Based on the review and sorting of existing literature,the following four key issues to be solved in this study are sorted out:1.How to design and implement the probability and statistics activity experience course for Junior Three students?2.What is the influence of probability and statistics activity experience course on the data analysis literacy of Junior Three students?3.What is the performance of data analysis literacy of Junior Three students who have experienced and have not experienced this activity course?4.How to cultivate students' data analysis literacy from the perspective of experience of basic mathematics activities?First of all,this study combined with the learning characteristics of Junior Three students and based on the basic activity experience theory of mathematics,designed and implemented the probability and statistics activity experience course,and evaluated and gave feedback to the course.Secondly,based on the literature sorting,the main dimensions of data analysis literacy are extracted,and the data analysis literacy test questions are compiled,applied to the survey,and the test results are statistically analyzed.Based on the analysis of after-class feedback survey results of activity courses and data analysis of literacy test results,the following conclusions can be drawn:1.The probability statistics activity experience course aimed at cultivating the data analysis literacy of Junior Three students has the characteristics of experiential,subjectivity and comprehensiveness;2.Junior Three students have certain data analysis literacy,and can collect and organize data and make progress simultaneously Simple analysis,but the ability to represent data is weak;3.Experience courses of probability and statistics activities can improve the basic abilities of data analysis literacy,mainly including data collection,sorting and analysis;4.In terms of non-cognitive factors,the probability and statistics activity experience course has a positive influence on the emotion,attitude,interest and other aspects of mathematics learning for Junior Three students.Based on the above conclusions,this study proposes three enlightenment on training strategies for data analysis literacy of Junior Three students:1.Combine traditional teaching of probability and statistics with activity experience courses;2.Make rational use of the Internet to assist teaching in activity experience courses;3.Pay attention to the diversification of activity situations.
