小学生图形几何概念的建构策略

Constructing Strategies of Primary School Students' Figure Geometry Concept

图形几何概念的建构过程中,我们可以让学生充分地感知物体和图形,通过操作探索来发现特征、通过归纳概括提炼特征、通过辩证辨析来提升思考力、通过变式练习来升华概念、通过创造设计来综合运用,通过生活运用,最终深度把握图形几何概念,从而切实有效地加强对学生空间观念的培养。

In the process of constructing graphic and geometric concepts,we can allow students to fully perceive objects and figures,discover features through operation and exploration,refine features through induction,improve thinking through dialectical analysis,sublimate concepts through variant exercises,and create The design is used in a comprehensive way,and through the application in life,the concept of graphics and geometry is finally grasped in depth,so as to effectively and effectively strengthen the cultivation of students'spatial concepts.
