Research On The Statistics And Probability Practical Assignment In Primary Mathematics

At present,the level of informationization in society is increasing,and various channels such as the Internet and the news media are flooded with a large amount of data.To see the nature of things,the statistical knowledge and data analysis concept have become the basic literacy that every citizen must master.Data analysis concept and application awareness belong to the ten core concepts of the Compulsory Education Mathematics Curriculum Standard(2011 Edition)and are important forms for students to experience and understand mathematics and the real world.The distinct application nature of Statistics and Probability determines that its content,expression and teaching methods are closely related to real life.Through the Statistics and Probability practical assignments,it is beneficial to the effective implementation of core mathematical literacy.In the Statistics and Probability section,students establish data analysis concept through a series of practical assignments such as investigation and analysis,further experiencing mathematical application,deepening their understanding of mathematical data analysis concepts and application awareness,and developing students' mathematical core literacy.Through questionnaire survey method,interview method on primary mathematics teachers' assignments design to cultivate students' data analysis concept and application awareness in Statistics and Probability,it is found that primary math teachers can clearly recognize the significance and value of data analysis concept and application awareness.But there are still many problems to be solved,including teachers' superficial training goals for statistics and probabilistic assignments,.differences between assignments and students' real situations,improper integration of practical assignment design and knowledge of various sections,and teachers' simple evaluation of practical assignments.The above problems are caused by many factors such as from schools,families,students.However,in terms of the implementation of Statistics and Probability practical assignments,teachers play a key role.For example,teachers lack accurate knowledge of Statistics and Probability practical assignments,lack of design guidance for Statistics and Probability practical assignments,and ignore the evaluation feedback of Statistics and Probability practical assignments.These are the main reasons for the above problems.Based on the analysis of the above problems,the reference to previous studies,the theory of mathematization of Freidenthal,the Compulsory Education Mathematics Curriculum Standards(2011 Edition)and the physical and mental characteristics of primary school students,the Statistics and Probability practical assignments in primary mathematics can be optimized through the following strategies.First,accurately grasp the characteristics of Statistics and Probability practical assignments.Second,flexibly design topics in Statistics and Probability practical assignments.Third,reasonable selection of Statistics and Probability practical assignments.Fourth,conduct multivariate Statistics and Probability practical assignment evaluations.Fifth,establish a home-school community cooperation support operation security system.Through the above strategies,on the one hand,the effectiveness of teachers in designing Statistics and Probability practical assignments can be improved;on the other hand,students can develop their data analysis concepts and application awareness in completing the Statistics and Probability practical assignments.In this way,teachers and students can understand the nature of things through complex data,grasp the laws,and use the laws.
