高中数学新课程立体几何教学中的问题与思考

Problems and Thoughts in the Teaching of Three-dimensional Geometry in the New Mathematics Course of Senior High School

高中数学立体几何是一门模型式的学科,立体几何教学的开展对于高中学生的空间感和想象力的培养产生有重要的影响。和其他学科对比看,直观思维的方式在立体几何学中占据着主要的位置,教学中发挥模型优势来增加学生的立体感与空间想象力,使学生好奇心与创造力的提高发挥重要的作用。正因为立体几何学科的教学对学生有着极为重要影响,所以有必要对于新课程背景下立体几何教学中存在的问题及有效解决方法进行思考。

solid geometry of mathematics in senior high school is a model subject.The teaching of solid geometry has an important influence on the cultivation of students'sense of space and imagination.Compared with other subjects,intuitive thinking occupies the main position in the field of solid geometry.In teaching,the advantages of models are used to increase students'three-dimensional sense and spatial imagination.The improvement of students'curiosity and creativity plays an important role.Because the teaching of solid geometry has an extremely important influence on students,it is necessary to think about the problems existing in the teaching of solid geometry under the background of the new curriculum and how to solve them effectively.
