The Research About The Teaching Of Solid Geometry In The Background Of The New Course

The education value of geometry had decided the three-dimensional geometry in the past, the present and the future all will be one of high school mathematics curriculum core contents. Around 2001, the wide range elementary education curriculum reforms in our country starts, the elementary and middle schools geometry curriculum reforms dynamics to be the biggest, the high school mathematics curriculum standard in the idea, the content, the method poured into the new vigor for the three-dimensional geometry teaching, the essence which the geometry curriculum reformed stepped out the practical step on the path of geometry algebraized.This article first uses the literature analytic method, traces and discusses the geometry discipline and it's teaching development history as well as the " Klein - Perry motion" and the " New mathematics athletics " to Euclidean geometry impact, has made the summary and the discussion to the geometry education value. In this foundation, take time vicissitude as the background, using theory discussion law, analyzes reality which Euclidean geometry the limitation and the geometry curriculum reforms, using the case analytic method and summarizing the experience, considers the geometry teaching under the new curriculum background. In this research, the key consideration is: How can the geometry education value under in the new curriculum background three-dimensional geometry teaching better manifesting. Through the article in 14 cases, try hard to manifest the three-dimensional geometry teaching the education value: Enhances through the three-dimensional geometry study grasps spatial and the graph ability, thus knew and understands the human survival well the space.The writing goal of this paper one is borrows dissertation writing opportunity, summarizes for 10 years three-dimensional geometry teaching experience; Two, the union pedagogy, the psychology theory makes the essential discussion to three-dimensional geometry teaching under the new curriculum background. Then the viewpoints of the author's himself were bought up.An important viewpoint in this article is: The algebraization of geometry reduced the high school three-dimensional geometry overall difficulty, can enhance the high school student's mathematics study confidence. The connection of vector, visualization, the deduction reasoning and the method that geometry algebraized manifests the geometry curriculum well the education value.
