Some Problems And Countermeasures Of Geometry Curriculum In Junior High School

As one of the oldest educational subjects, geometry has a long history which is spectacular. As we all known, with the founding of Euclidean geometry in ancient Greece, with the development of analytic geometry and other kinds of geometries, with F.Kline' s Erlanger program in 1872 and the new developments of geometry in 20th century such as topology and so on, man has developed their understand of geometry. On the other hand, Euclid formed geometry as a deductive system by using axiomatic theory for the first time. The content and method of geometry have dramatically changed, but the geometry curriculum has not changed correspondingly until the first strike from Kline and Perry' s appealing. During the course of the well-known "new mathematics" campaign, the status of Euclidean geometry was completely overthrown in I960' s. After deeply thought of "new mathematics" , the standpoint that geometry curriculum should reflect the content and method of modern geometry and be in touch with the student' s real life was agreed on. Other countries have tried some significant attempts. We can find from some geometry textbooks that the methods of transform and vector have appeared as a normal part. Simultaneous, not only the new developments of geometry such as Topology have been referred , but also the connection between geometry and practice has been strengthened.In China, geometry curriculum is also in the during of innovation. After analyzing the problems of traditional geometry curriculum in junior high school, we can find that the key of innovation lies in two factors, reflecting the content and method of modern geometry and closing to the student's real life at the same time. To conquer the found problems need to consider many more factors including geometry, student's psychology, demand of the society and so on.Considering the fact of our country's geometry curriculum, I start off from "opened geometry" , analyze the problems of geometry curriculum in junior high school, and then give the countermeasures.
