A Comparative Study On Geometric Proof Part Of Geometry Teaching Material In Middle And High

Geometric proof is an important module in the curriculum of geometry, is an important part in the teaching of geometry, and is also one of the elements of senior geometry curriculum reform. The teaching material is the concrete embodiment of the curriculum target and the teaching content, whether it’s pros and cons has a direct impact on the implementation of curriculum standards in place, the quality of teaching effects, the reform of teaching material is one of the important contents in the curriculum reform. The compilation and reform of senior mathematics teaching material often draw on some experience and material that have made outstanding achievements in mathematics education, the Netherlands senior mathematics teaching material Profi geometry series "Geometry with applications and proofs" has permeated "the realistic mathematics" education thought which is extremely affirmed in the international mathematics education circles, the geometric proof part also has its own features, there is a certain reference meaning for enriching the thought and content of the high school geometry proof in our country.In this paper, from the perspective of geometric proof, with the senior geometry teaching material as the vector, static text analysis on mathematics textbooks of Beijing normal university edition and the Netherlands senior geometric teaching material, compare with the whole situation of teaching materials, draw the following conclusions:1.The two textbook pay attention to the students’subjectivity and connection with the real life, but the way of dealing with the teaching material is different;2.The textbook of Beijing normal university edition of the geometric content is rich, the Profi textbook content is relatively concentrated;3.The textbook of Beijing Normal University focus on modules divided of knowledge points, the Profi textbook focus on knowledge migration refining knowledge points.Specifically it around two set of identical teaching materials content geometric proof part, draw the following conclusions:1.The textbook of Beijing Normal University’s proof process is focused, the process of proof of the Profi textbook emphasize the details;2.The textbook of Beijing Normal University include complete steps, the process of proof of the Profi textbook is more in-depth and concrete;3.The textbook of Beijing Normal University focus on synthesizing other content, the Profi textbook focus on the use of information technology.Based on the above conclusions, absorb the excellent and can be used for reference in the teaching material of Holland to learn, the aim is to put forward some useful suggestions for our country’s senior geometry proof, perfect the setting of senior geometry teaching material in our country, make some substantial changes in geometric proof teaching.
