Analysis Of Applied Problems In High School Mathematics And Research On Teaching Strategies

In recent years,the application of mathematics has been greatly developed,and the application of mathematics has become an important problem in the teaching of mathematics."General high school mathematics curriculum standard(2017 Edition)"points out that high school students should cultivate six key competencies in mathematics learning,and the mathematical modeling is the third one.The application of the college entrance examination has also emerged in the examination papers all over the years.In addition,through the teaching of mathematical application questions,students can cultivate the ability to analyze problems and solve problems.Based on the above thinking,this paper tries to make theoretical research and practical exploration from the perspective of application question preparation,through literature research,questionnaire survey,case analysis,interview and practice research.First of all,defined by the method of literature research of mathematics application problems and other core concepts;secondly,through the questionnaire survey to understand the actual situation of teaching teachers and students;third,in recent years,college entrance examination questions for further evaluation and analysis based on the existing research results;fourth,through interviews and have compiled application problems experienced teachers to exchange ideas;finally,through classroom practice;the formation of the preparation of the teaching strategy based on application.After the above study,the following conclusions are obtained.(1)Investigation and research shows that the scoring rate of mathematics applied problems is far lower than that of mathematics.Teachers and students still don't pay enough attention to it,so we should strengthen the teaching of mathematics application problems.(2)The overall stability of the college entrance examination questions in Jiangsu Province in the last ten years is at a high level,but it is not stable in the focus of knowledge and the moderation of calculation.From a modeling perspective,the geometric background is most common,mainly from the point of view of knowledge,there are almost every function most value knowledge,from proposition style,tend to life some of the students easy to understand the problem,the overall stability is not new.(3)Interview research shows that in daily practice teaching,we should base on the cultivation of mathematical modeling literacy,and leave the opportunity of exploration and practice to students,so that students can experience the real modeling process.The following four methods:the adaptation method of questioning,the creation of the modeling opportunities;deep understanding of context,the initial modeling scheme;multi mode model test method,explore the optimal solution;the evaluation of self reflection,the accumulation of experience(4)The application method is summarized as follows:1.Confirm the background of the topic and examine the goal;second,confirm the content and mathematical model;third,confirm the model data and deliberate carefully;(5)In the practice teaching of applied questions,we use five teaching strategies:first,situational teaching strategies;second,step by step strategy;3,representation of teaching strategies;4.Pattern recognition strategies;5.Successful experience strategies.
