Investigation And Research On The Present Situation Of Mathe Matical Modeling Teaching In Senior Grade Of Primary School

The mathematics curriculum standard for compulsory education advocates that mathematics teaching requires students to solve problems based on practical problems and abstracted into mathematical models.It is of great value to cultivate students’ mathematical consciousness and cultivate students’ mathematical innovation ability and problem-solving ability.With the increase of mathematical knowledge learning,the complexity of mathematical problems in the higher grades of primary school increases,so they need to use mathematical modeling to solve mathematical problems,which needs to be paid attention to.In order to understand the current situation of mathematical modeling teaching in senior primary schools,this paper takes Qinhuangdao City,Hebei Province as an example to carry out relevant investigations.The research questions of this paper are:(1)the current situation and existing problems of mathematical modeling teaching for senior primary school students?(2)What kind of teaching strategy should be adopted for mathematical modeling in senior primary school? In the research,the questionnaire survey method is implemented,and the mathematics teachers and students in the upper grade of primary school are selected as the research objects.The survey dimension carried out a questionnaire survey around the construction of practical problems,preliminary perception of the prototype of mathematical models,variable analysis and assumptions,mathematical modeling formula construction,model solution and verification,mathematical model correction and application,and analyzed the results.The results show that the existing problem of teaching in the model preparation stage is that the practical problem is not open enough;The mathematical problem design scenario is relatively simple.Lack of guidance for students to perceive the mathematical model;The hypothesis of variable analysis is not reasonable;Mathematical modeling formula construction lacks depth of thinking;Heavy model solution light model verification;The lack of model revision and application implementation is reflected in the lack of rigor of model revision;The model is less popularized and applied.Combined with the existing problems and cause analysis,this paper puts forward the following six strategies.First,design mathematical problems based on practical problems.Specifically,it includes the development of mathematical problem design;Mathematical problem design scenario reflects reality.Second,with the help of mathematical thought,we can perceive the mathematical prototype.Including the mathematical prototype of autonomous problem classification and perception;Attach importance to assumptions and conjectures.Third,the plausibility of variable analysis and assumptions.Including the use of mathematical methods to analyze model variables;Based on the comprehensive analysis of variables established by idealization hypothesis;Data assumptions are reasonable.Fourth,the construction of mathematical models focuses on the implementation of deep thinking training.Specifically,it includes the comparison and optimization of various mathematical models based on innovative thinking;The transformation between mathematical models focuses on the quantitative relationship.Fifth,the flexibility to carry out model solving and verification.Specifically,the model solving method focuses on calculation;Carry out model validation to return to reality and solve problems.Sixth,cultivate the ability to solve problems independently in the application of the model.Specifically,it includes cultivating scientific thinking in the revision of mathematical models;Carry out independent application and promotion of mathematical modeling.
