A Teaching Research Of Statistics Andprobability Of Developing Students’ Concept Ofdata Analysis In Junior High School

In 2001,"statistics and probability" was a new section.In 2011,the concept of "statistical",which was one of ten core concepts,was renamed as "data analysis" by Compulsory Curriculum Group,and attached high attention.The application of statistics and probability theory exist in every corner and every way in our work and life,reflecting the importance of the concept of development in the process of data analysis in statistics and probability of the students.On the basis of the related research,this study also analyzes its connotation,using questionnaire survey method,text analysis method,observation method,interview method,such as research methods.The paper analyzes the existing problems in the teaching design of statistics and probability in the development of the concept of students’ data analysis,and the cause of these problems,and also designs in view of the actual situation of the case.Through research,the study finds the following problems existing in the concepts of data analysis in junior high school students:(1)Due to the teacher’s lack of understanding for data analysis of the concept connotation and the backdrop of the exam-oriented education,it makes junior high school students the low level of development of the concept of data analysis.(2)The teacher does not attach great importance to the application of data analysis method.In the teaching design,teachers usually emphasized the calculation methods of master,but ignors the cultivation of the concept of data analysis.(3)Because the teachers emphasizes on frequency,probability concept teaching,but does not make students experience the randomness in the whole process of data analysis in the teaching design,students are not aware of laws can be found from the data analysis,so students fail to correctly understand the relationship between frequency and probability.In view of the existing problems,it is concluded that the junior middle school teaching statistics and probability design,the main points of the curriculum requirements,rich in curriculum requirements,applied teaching goal;Creating realistic activities,let the students to fully experience the randomness;The design of typical cases,pay attention to the diversity of data analysis methodsOn this basis,the teacher put forward some Suggestions:(1)the required statistics,probability knowledge.(2)of the modern education technology.(3)good at collecting and using real-life examples.(4)careful activity,pay attention to essence.
