Three-dimensional Geometry Curriculum And Research

Proceeding from the value of geometry curriculum (natural value philosophical value aesthetic value practical value and intellectual value), this article elaborated the necessity of offering the curriculum of solid geometry. By analyzing the process of development of Mathematics Curriculum Standard Mathematics Teaching Program and Solid Geometry teaching material, compared the development of solid geometry of our country vertically. In the respect of ideas and principle of setting up curriculum accepting or rejecting of curriculum content the structure arrangement of curriculum content the way of dealing with the method of thinking of geometry dealing .with the applying of geometry in the real world, compared with the curriculum of solid geometry of U.S.A and Russia, which are both mainstream countries of mathematical development in the world of today. Selected the essence and discarded the dross, so as to draw some enlightenment for the set-up of solid geometry of our country: (1) the importance of geometry object; (2) reducing the starting point of the curriculum of solid geometry; (3) grasping the yardstick of abridgment of geometry content; (4) changing "invisible" geometry thinking into "visible"' one; (5) improving the way of dealing with the applying of geometry.On the base of these, and the ideas of mathematical curriculum reform and the course of the reform of solid geometry, combining with educational reality and students' psychology, put forward some thoughts about solid geometry of middle school in future: (1) The arrangement of curriculum content should. give consideration to both the logical sequence of knowledge and the development of students' psychology, and make them united; (2) Paying great attention to the analogy of plane geometry and solid geometry; (3) Some respects remained to be strengthened about solid geometry in senior middle school; (4) Emphasizing the importance of conversion in solid geometry; (5) Stressing on the combination of solid geometry and algebra and other subjects; (6) The design of the content of solid geometry should have certain elasticity, and make solid geometry and modern education technology well combined.This study tried to excavate deeply enterprise and strictness characteristic about solid geometry of U.S.A and Russia, mixed with understanding and sentiment, proceeding from related theory on solid geometry. Looked closely at the set-up of the curriculum of solid geometry again and searched for a new way, expecting to offer some valuable reference for the set-up of solid geometry of our country' s middle school in future.
