Research On Teaching Strategies Of Training Secondary Vocational Students' Data Analysis Literacy

In the era of big data,society and all walks of life are increasingly demanding citizens' data analysis literacy.Having a certain level of data analysis literacy is an important skill for people to adapt to the future societyPrimary school,junior middle school and senior high school attach great importance to students' data analysis concept,data analysis ability and data analysis literacy,while vocational education pays little attention to students' data analysis.The vast majority of secondary vocational school students directly enter the society after graduation.Training secondary vocational school students' data analysis literacy has a positive role in promoting their adaptation to the rapid development of the future society.The teaching of statistics in mathematics is an important way to cultivate secondary vocational students' data analysis literacy.Through searching literature,it is found that there are few studies on data analysis of secondary vocational students.The status quo of secondary vocational students' data analysis literacy,the composition of secondary vocational students' data analysis literacy and the teaching strategies of training Secondary Vocational students' data analysis literacy are scarce.Because the teaching content of mathematics course in secondary vocational education is similar to that in general senior high school education,referring to the existing research foundation of senior high school students,combing the related concepts of senior high school students' data analysis literacy,combining with the teaching syllabus of secondary vocational mathematics,four dimensions of data awareness,basic concepts and principles of statistics,data collection,collation and representation,data analysis and statistical inference are established.Secondary vocational students' data analysis literacy index system of each index.According to the data analysis literacy index system of secondary vocational students established in this paper,a questionnaire for students and teachers and a test paper for students are designed.Questionnaires were used to investigate the learning statistics of secondary vocational school students,and test the data analysis ability of secondary vocational school students with test papers.Questionnaires were used toinvestigate the reality of secondary vocational school teachers' training of secondary vocational school students' data analysis literacy.The survey found that the data analysis literacy of secondary vocational school students is generally lack,in order to change the status quo and culture the number of secondary vocational school students.According to the analysis literacy,based on the combing of modern learning theory and modern teaching theory,this paper puts forward seven teaching strategies to cultivate secondary vocational students' data analysis literacy.Including enhancing data analysis awareness;selecting realistic mathematical problems;based on data analysis principles;implementing data analysis process;deepening data representation;focusing on data analysis context;enriching data analysis means.Finally,two teaching cases,Estimating the Overall Distribution with the Frequency Distribution of Samples and the Relevance between Variables,are designed to demonstrate the application of the teaching strategies in practical teaching.
