Study On The Educational Value Of Mathematical Modeling Course Teaching In Primary School

In primary school mathematics teaching,the content teaching of "problem solving" is self-evident in cultivating students' thinking quality.The so-called "problem solving",in the existing primary school mathematics teaching material,mainly consists of two parts: one part is the quantitative relationship problem,such as total problem,and poor problem;The other part is the classical problems of mathematics,such as interval problem(tree planting problem),frequency problem(shaking hands problem),material saving problem(packaging problem),time saving problem(pancake problem),etc.,these are mainly scattered in the textbook "mathematics wide angle" or "smart square".During the graduate study period,the author listened to nearly a hundred classes,among which there were a lot of questions about "problem solving" teaching,especially elementary mathematics classics.In the teaching practice,teachers not only lack the understanding and development of the value of these content education,but also lack the research on the practical exploration of the teaching process embodying the value of education,leading teachers to be limited to the problem-solving content of problem solving.In teaching,students are stuck with problem-solving drills.In view of the problem of narrowing the value of educating people in "problem solving" teaching,this study attempts to use the classic problems commonly found in primary school mathematics textbooks as research objects,develop and expand the educational value of "problem solving" teaching in primary school mathematics,and explore and summarize refinements.The general structure of the teaching process of education value,and based on the process characteristics and forms of its teaching modeling,the teaching of this kind of content is named as the primary school mathematics modeling course teaching.This study focuses on the teaching practice of "problem solving" in primary school mathematics,mainly using classroom observation,case analysis.Through a large number of "problem-solving" teaching classroom observation,found and clear research problems,and then to collect and record the classroom record,teaching design and after-class discussion and evaluation,according to the common mathematical classic problems in the textbook this research object further sorting and screening,focusing on the selection of representative typical cases for specific analysis and elaboration.In addition,actively in-depth classroom,and first-line teachers experience the process of reconstruction of classroom teaching,in theprocess of attention and discussion modeling class teaching educational value transformation process structure and promote the realization of its educational value of teaching basic principles.Based on the theme of educational value of mathematical modeling course teaching in primary schools,the logic of this paper is: firstly,through classroom observation,we find out the problems in this field of teaching,and analyze the main reason of the problems is that the teachers lack of understanding of the rich educational value behind this kind of content.Then try to realize,develop and transform the educational value of this kind of content teaching,design the teaching process structure and basic principles that embody this educational value,and make a specific explanation with the case.According to this logic,the paper mainly includes the following parts: the first part,according to classroom observation found that there are many phenomena in primary school mathematics "problem-solving" teaching,due to the limited personal ability and time and energy,so focus on the selection of closely related to the study of two phenomena,mainly constrained in the teaching material problem-solving,ignore the problem-solving methods,focus on the presentation of results,ignore the process of knowledge formation,and then from the "problemsolving" teaching value of education lack of understanding,lack of understanding of the relationship between daily penetration and centralized teaching of the two aspects of problems and causes analysis.The second part,in order to solve these problems,we must first realize the educational value of the teaching content in this field.the educational value of these teaching content is not without,but hidden in the teaching content itself,teaching methods and tools,covered by the conclusion,teachers in teaching easily pay attention to the memory and application of the conclusion,ignore the educational value of the knowledge formation process to the growth of students.Secondly,on the basis of this understanding,from the perspective of the teaching content itself and the teaching process,based on the knowledge content,the formation process of knowledge content and the mathematical thinking method embodied in the process of primary school mathematics modeling course teaching value of education.To undertake the development of educational value,into exploring how to realize the transformation of educational value in the specific modeling class teaching,namely through field intervention research,summed up the two modeling class teaching process structure.In the last part of the thesis,according to the logic of the process structure of primary school mathematics modeling course,the basic principles ofteaching to promote the realization of the educational value of primary school mathematics modeling course are explored.Through a large number of classroom observations and in-depth analysis of the reconstruction cases,this study formed the following main points and conclusions:first,the primary school mathematics "problem-solving" teaching for the growth and development of the value of students: the formation of students' basic methods and experience in mathematics learning,the formation of students' algebra learning basic logic and abstraction.Secondly,in order to make teachers embody the value of educating people in teaching,according to the logic of teaching process,this study has formed two kinds of teaching process structure through practice exploration and induction: one is the process structure of orderly reasoning induction modeling,the other is the process structure of classified enumeration induction modeling.Finally,based on the logic of the teaching process,the basic principles of teaching to promote the realization of the educational value of primary school mathematical modeling curriculum are: stimulating students' desire to explore,encouraging active and orderly research,building steps to support the principle of auxiliary,summarized abstract expression principle,flexible use of mathematical model principle.
