Developing Students Space Imaginary Abilities In The Teaching Of Geometry

Space imagination refers the people' ability in observation, analysis and abstract on objective things' spatial form. The geometry is the mathematic study of an object's the shape, the size and the position relations in the real world. It was demonstrated that the geometry education has a close relationship with the cultivation of spatial imagination ability. Through the three-dimensional geometry study, the students could grasp the geometric figure, and sharpen the spatial ability, thus better understand the human survival space. Previously, there was an enormous amount of domestic and foreign significant work and the effective exploration on the spatial and spatial imagination ability, but seldom connected with the high school stage. This article, which took the spatial imagination ability as a goal and, tried to elaborate the development level and the structure of the high-school pupils' space imagination ability, and proposed the teaching measures for the elementary education's reference. This article discussed as follows:First, Elaboration on the concept limits of space imagination ability and research results related spatial imagination ability. Elaboration on the influence of geometry curriculum's change on the spatial imagination ability with the implementation of reform of new curriculum, On one hand, The cultivation of spatial imagination ability was highlighted from the teaching content (Three views) to the teaching method (educational technique); on the other hand, the geometry algebra would affect the students' space imagination abilitySecond, suggestions on the corresponding teaching strategy which unified individual experience aiming at the problems in the teaching and learning of spatial imagination ability.Last, Uses the spatial imagination ability test, analyzes the high-school student the development level and the structure of space imagination ability. The situation is the high school student already has the construction space representation ability through the high-school pupil space imagination ability condition, but spatial representation operation ability was bad. Though analyzes the test, propose the teaching suggests.
