Research On Mathematics Experiment Teaching Of Statistics And Probability In Junior Middle School

Statistics and probability is one of the main contents of junior middle school mathematics education,which plays a vital role in cultivating people's data analysis concept and application consciousness.However,the teaching materials are not closely linked,the data collection is restricted by time and space,and students are affected by the "certainty" thinking set,which brings certain difficulties to the teaching of statistics and probability in junior high school.Based on this,this paper studies the mathematical experimental teaching of statistics and probability in junior high school.The main contents are as follows:Chapter one: it briefly reviews the teaching status and existing problems of statistics and probability in junior high school and the research status of mathematical experimental teaching,and introduces the main research content and significance of this paper.Chapter two: carries on the theory analysis to the junior high school statistics and the probability mathematics experiment teaching,introduced the correlation concept,the theory foundation and the teaching principle.Chapter three: firstly,it discusses the necessity of experimental teaching in statistics and probability in junior high school from the perspective of curriculum standards,and discusses the feasibility of experimental teaching methods from the materials of textbooks,the development of information technology and the attitude of teachers and students.Secondly,this paper introduces the design structure of validating,exploring and understanding experiment in mathematics teaching,and puts forward the teaching strategy of statistics and probability experiment in junior high school on this basis,and finally gives the example teaching of this teaching strategy applied in teaching materials.Chapter four: based on the principle of process and development of mathematics experimental teaching evaluation,an evaluation system with teaching content,teaching method,teaching process and teaching effect as the first level index is established,and a comprehensive evaluation model of intuitionistic fuzzy aggregation operator is constructed.Finally,the feasibility and effectiveness of the method are verified by an example.Chapter five: summarize the research and put forward the value and reflection of the experimental teaching of statistics and probability mathematics in junior high school.
