对“几何直观”的理解分析及其能力的培养

The understanding and analysis of "Geometry intuition" and the cultivation of its ability

"几何直观"是《全日制义务教育数学课程标准》(修改稿)的核心概念之一,是指借助几何图形来认识事物、分析问题。几何直观在数学的学习研究中具有举足轻重的作用,对它的认识与理解是实施数学课程的基础。几何直观具有一定的教育价值。因此教师应当重视几何直观的培养,在联系生活、重视学生的动手操作、加强数形结合等方面来培养学生的几何直观能力。

'Geometry intuition' is one of the core concepts of ' Mathematics Curriculum Standard of Full-time compulsory Education'( revision),refers to the understanding of things and the analysis of problems by means of geometric figures. Geometry intuitionism plays an important role in the study of mathematics. Understanding of it is the foundation of implementing mathematics curriculum. Geometry intuitionism has certain educational value. Therefore,teachers should attach importance to the cultivation of geometric intuition,and cultivate students’ ability of geometric intuition by connecting with life,attaching importance to students’ hands-on operation and strengthening the combination of numbers and shapes.
