Research On Teaching Strategy Of Mathematics Modeling Under The Requirements Of New Curriculum Standard In High School

The promulgation of the "Ordinary High School Mathematics Curriculum Standard(2017 Edition)" marked that mathematical modeling as one of the six core qualities of mathematics entered the high school mathematics classroom.Based on the requirements of the new curriculum,this paper puts forward the teaching strategy of modeling and gives a case analysis,which aims to provide reference for the teaching of high school mathematics modeling.Firstly,through questionnaire survey and teacher interview,this paper finds out that the present situation of mathematics modeling teaching is as follows: the teachers and students of the first line are full of expectations for modeling teaching under the new curriculum,but they are also trapped in the lack of systematic teaching strategies to guide teaching.Through the literature research method,it is found that the relative research on the teaching strategy of mathematical modeling under the new curriculum is very scarce,and it is not enough to support the current modeling teaching.Therefore,this paper studies the specific requirements of the new curriculum standards in the modeling teaching section,draws on the US STEAM curriculum,and puts forward modeling teaching strategies based on meta-cognitive theory and Bruner cognitive structure learning theory.Strategy one: the teaching strategy of cross-boundary topic modeling.Students are encouraged to connect with the reality of life,cross the subject area,find mathematical problems,build mathematical models,and solve practical problems.Strategy two: group inquiry modeling teaching strategy.More students will be returned to the modeling classroom to encourage students to cooperate in modeling learning and express mathematical models in mathematical language.Strategy three: teaching strategy of variable innovation modeling.In the modeling teaching,students are guided to think from many angles,constantly improve the model,and learn to speak against each other.Strategy four: teaching strategy of model step by step.Through the teaching of typical sample,step by step,gradually familiar with the modeling process,deepen the understanding of the model,experience from special to general modeling ideas.Strategy five: teaching strategy of information technology solving modeling.List the applications of commonly used mathematical software in Excel,lingo,Python,and Matlab in mathematical modeling,emphasizing the value of information technology in mathematical modeling teaching.Strategy six: self-evaluation modeling teaching strategy.The three levels of mathematical modeling corresponding to the new curriculum require self-evaluation of the modeling classroom.While achieving mathematical knowledge and skills,we pay attention to the improvement of students 'comprehensive literacy.Finally,the case analysis method is adopted,and the model teaching strategy is used to analyze the parking distance problem case and the shoe number problem case.This paper puts forward six modeling teaching strategies by analyzing the modeling teaching requirements of the new curriculum,and analyzes the typical modeling cases after the new curriculum,so that the first-line teachers can experience the application methods of modeling teaching strategies and inspire them to modeling teaching.New ideas.It provides reference for high school mathematics modeling teaching.This improves the quality of modeling teaching in high school and enables students to obtain good development.
