The Teaching Research Of Probability And Statistics Based On Data Analysis Literacy

Probability and Statistics experience a long period of natural selection,has an unshakable status,which contains the awareness and ideas are widely used in various industries of life,is the knowledge guarantee of dealing with practical problems with high quality.From elementary school "the possibility of winning or losing,the fairness of the game,the average expectation" to the junior high school stage “weighted average,with the charts to describe the data,the possibility of the occurrence of events”,and so on.It can be seen that the Probability and Statistics of the compulsory education stage is very suitable for the students' life and rich and exciting.The probability and statistics course in senior high school is to enhance the breadth and the depth of difficulty on the basis of the previous study,thus laying a solid foundation for the students to continue to study and enter the society in the future.In September,2016,the revision group of senior high school mathematics curriculum standards officially published six mathematics core literacy,among which data analysis literacy is the most closely related to Probability and Statistics.It can be said that data analysis literacy is the soul and essence of Probability and Statistics.Based on the quality of data analysis,the teaching research of probability and statistics course is carried out in this paper.Chapter 1,mainly through the literature research method,makes a general narration and explanation of the historical development of our country background,the research questions and significance,the domestic and foreign research status,the research methods,etc.Chapter 2,The author summarizes the teaching requirements and training directions of Probability and Statistics after reading the curriculum standard and teaching material,and analyzes the national volume and Sichuan volume in the past five years,and then the related concepts commonly used probability and statistics.Such as data analysis literacy,mathematics thinking and methods to do a summary of interpretation.Chapter 3,through empirical investigation,aware of the basis of probability and statistics knowledge and the level of daily experience of senior one students in the context of primary and secondary education,and analyze the senior three students of their understanding and awareness of the concepts and ideological methods of probability and statistics,application and common problems.In addition,I also visited the actual classroom,and studied the first line teachers' teaching content,mode of treatment.Chapter 4,on the basis of previous investigation and research,through the three front-line teachers face to face interview,put forward five points of probability and statistics teaching advice for data analysis literacy: 1.Enrich the classroomexamples,emphasize the background of data;2.Attach importance to process participation,understand the randomness of data;3.Strengthen the integration of concepts and understand the coherence of the discipline;4.Establishing Mathematical Model and showing the application of the discipline;5.Pay attention to the thought method and internalize the literacy of the discipline.Chapter 5,the conclusion and the prospect part mainly elaborated the feeling to the Probability and Statistics,the innovation and deficiency of this paper,and the expectation of it.
