空间想象能力的提升要经过以下几个阶段:空间知觉、空间表象、空间想象,最后提升学生的空间想象能力。知觉、表象、想象直至能力的提升,需要一个教学手段——“动静结合”。关于空间与图形试题考查的内容大体分为两方面:“静态与动态”。所谓静态,是我们常常关注的几何图形表现出的结果状态;而所谓动态,则可以理解为这些几何图形在一、二、三维之间转化的动态过程(包括三视图、展开与折叠、变换等)。合理结合动态和静态的呈现方式,有助于学生提升空间能力,丰富对几何图形的全面认知。
Space to enhance the ability to imagine through the following stages: the perception of space, the appearance of space, space imagination, and ultimately enhance students' spatial imagination. Perception, appearance, imagination until the ability to upgrade, you need a teaching tool - “movement combination ”. On the space and graphics test examines the content is generally divided into two aspects: “static and dynamic ”. The so-called static, is the result of the geometry we are often concerned with; the so-called dynamic can be understood as the dynamic process (including the three view, expansion and folding, transformation, etc.) ). Reasonable combination of dynamic and static presentation, help students improve their spatial capabilities, enrich the overall understanding of the geometry.
