The Application Research Of "re-creation" Education Thought In The Teaching Of Flat Graphic Area In Primary School

The mathematics education theory of "re-creation" put forward by Dutch mathematics educator Friedenthal has been widely recognized and widely studied by mathematics educators at home and abroad.At the same time,It caters to the students' mathematics learning idea advocated by the new curriculum reform in many aspects and provides us with a kind of teaching thought that can be used for reference.In classroom teaching,students are the main body of learning.Therefore,how to promote students' participation in class and how to improve students' overall learning level are worth studying.Attention should be paid to the students as the main body in teaching Vladenthal's "re-creation" educational thought points out that mathematics teaching is a process of mathematics,and that it is the students themselves who discover or create what they want to learn.By applying the educational thought of "re-creation" to the teaching of plane figure area in primary school,this paper focuses on the study of the influence of "re-creation" teaching on the students' overall level and the students' participation in the classroom.This article is divided into six chapters.This article is divided into six chapters.The first chapter is the introduction.The introduction mainly analyzes the background of the topic,and shows the research problems,research methods,research objectives and significance.The standard analyzes the background of the topic in the teaching of Graphics and Geometry.Keywords: recreating,mathematical reality,mathematical,graphic area,teaching activities.The second chapter is the summary of the research,which is mainly summarized from three aspects.First,it summarizes the geometry cognition of primary school students.This paper mainly analyzes the characteristics of the development of pupils' spatial thinking level and the characteristics of pupils' learning geometry.Secondly,it summarizes the current situation of primary school plane graphic area teaching.This paper introduces the applied research of the teaching theory of "re-creation",mainly from the aspects of "re-creation" teaching principle,"re-creation" teaching link and process,and "re-creation" teaching implementation strategy.Chapter 3 systematically introduces the connotation of Friedenthal's educational thought of "re-creation",and gives a detailed introduction to "Mathematical reality","Mathematicalization","guided Recreation" and "reflection".On the basis of Friedenthal's thought,the author gives a reasonable explanation on where to guide,where to guide and how to guide in guided re-creation.Chapter 4,based on the analysis of the connotation of the educational thought of "re-creation",puts forward the teaching strategy of "creating" the area of plane figure under the guidance of "re-creation" education thought: "creating situation",and motivating students to "re-create" the motive of "re-creation".To guide students to "mathematical" thinking sublimation,to guide "re-creation" and 4)to reflect and generalize,to consolidate students' knowledge construction,each step is explained by a teaching case of plane figure area.Chapter 5 is the experimental research of "re-creation" teaching.By adopting the method of wheel group experiment,two parts of adjacent mathematics content are chosen to take turns in two parallel classes with different teaching methods.Through the comparative analysis of the test results of each class,it is concluded that the teaching idea of "re-creation" is helpful to improve the students' learning level,and through the analysis of the students' participation in the questionnaire,It is found that students' participation in emotion and behavior in mathematical activities under the guidance of "re-creation" is much higher than that in conventional teaching.Chapter 6 is the conclusion and prospect of the research.The experimental results show that students have a high degree of participation in the teaching process of plane figure area.Most students are able to actively analyze problems,analyze problems and solve problems,and from the point of view of the test,The overall learning level of students is improved significantly,and the scores of non-top students are improved more obviously.From classroom observation and after-class questionnaire survey,students' emotional and behavioral participation are obviously superior to conventional teaching.Thus,the educational thought of re-creation is applicable to the teaching of plane figure area.In fact,it is a challenge for both students and teachers to apply the idea of "re-creation" education to the actual classroom teaching.Students in the whole teaching activities need to think,layer upon layer,reflection and generalization.Teachers should presuppose students' various ideas in advance,understand the students' mathematical reality,and design a reasonable teaching process.Be prepared for guided re-creation of students.
