The Research Of Teaching Of Plane Geometry Drawing In Junior High School

The teaching of plane geometry drawing is not only the important content of geometry teaching,but also the foundation of geometry teaching.Mathematics curriculum standards for compulsory education(2011 edition)has clear requirements for the content of drawing teaching.Plane geometry drawing teaching not only plays a crucial role in cultivating students' spatial concept and developing their geometric intuitive ability,but also plays an important role in the formation of general accomplishment outside the mathematical category,namely the application consciousness and the innovation consciousness.In the previous literature,study of plane geometry drawing method,especially the ruler gauge mapping method is more,but on the teaching of plane geometry mapping research is very rare,based on the above background,based on the plane geometry drawing teaching as the research object,using literature study,questionnaire investigation,observation method,interview method,case method were studied.First of all,this paper briefly discusses the development and changes of the teaching content of plane geometry drawing since the founding of new China,and discusses the important role of plane geometry drawing teaching in teaching from different angles,and also analyzes the teaching method of plane geometry drawing.Secondly,by investigating students' learning situation of plane geometry drawing,the following five problems are found: first,students like the learning of plane geometry drawing,but do not understand the role of geometry drawing in mathematics learning,and they like blindness.Second,students have not developed the habit of using drawing tools to make standard drawings.Third,students do not know how to apply the knowledge of geometric drawing to life;Fourth,students' participation in learning plane geometry drawing is not high;Fifth,the biggest obstacle for students to learn plane geometry drawing is that they do not understand the drawing principle and cannot accurately memorize the drawing steps.Combination of questionnaire and classroom view,analysis the reason of the above problems in the process of students' learning and puts forward the corresponding teaching Suggestions: first,the student is like drawing the plane geometry,and this is the favorable factors of teaching,teachers should be in every link of teaching,trying to make students realize the drawing to the function of studying the mathematics learning plane geometry,and guide the students' interest in the direction of the rational development,fixed students learning interest of plane geometry drawing;Second,the cultivation of students' standard drawing habits needs a long-term process.Therefore,attention should be paid to the integration of the cultivation of standard drawing habits into the daily geometry teaching process.Students should not be eager for success and influence students imperceptibly so that they can gradually develop the standard drawing habits.Third,students do not know how to apply the knowledge of geometric drawing to life,because in teaching,teachers pay too much attention to the teaching of the knowledge of plane geometric drawing itself,but ignore its connection with reality.Therefore,teachers should pay attention to the practical teaching of plane geometric drawing.Fourth,students in plane geometry drawing,drawing myself of participation is not high,lead to this problem is the main reason for the teachers in teaching relies too much on the convenience brought by the multimedia auxiliary teaching equipment,ignored the demonstration of its effect on the student to study the plane geometric mapping,mapping process,students are not imitate teachers didn't learn,will not be able to personally participate in,therefore,teachers should pay attention to choose appropriate teaching methods in plane geometry drawing teaching,attaches great importance to teachers' teaching demonstration effect on the student to study the plane geometric mapping;Fifth,students do not understand the principle of drawing,not accurate memory mapping step is the biggest obstacle to a student to study the plane geometric mapping,teaching,teachers should pay attention to guide students to analysis the principle of drawing,so that the students not only learning,and know the why,analyzes the steps of the drawing by drawing principle,to achieve the effect of memory mapping steps correctly.Thirdly,this paper proposes the teaching design of making circles through known points and analyzes the case of the nature of Angle bisector,hoping to provide some reference and Suggestions for the majority of teachers in the front line.Finally,this paper summarizes the research conclusions and the enlightenment obtained in the research,and analyzes the limitations of the research and theoretical learning,and puts forward the direction of the follow-up research.In this paper,based on the teaching content of plane geometry drawing in junior high school in a broader sense,the research object is not limited to the drawing of rules and regulations,so as to enrich the related research of plane geometry drawing teaching and provide some feasible reference opinions for the teaching of plane geometry drawing by teachers in frontline schools.
