发展儿童的空间观念是数学教学的应有之义。空间观念的形成不是一蹴而就的,而是一个由浅入深、从形象到抽象的过程。空间观念的培养依赖于儿童的观察、想象、分析、概括等,发展儿童空间观念的最大障碍在于儿童“眼中有物,脑中无形”。“动态想象”是一种运动的想象,即儿童根据提供的材料和问题,对已有表象进行加工、组合,想象运动变化过程与结果。动态想象的背后有儿童丰富的表象支撑,渗透了儿童的推理、分析等,是儿童对数学学习材料展开的自主的、 The development of children’s space concept is the proper meaning of mathematics teaching. The formation of the concept of space is not accomplished overnight, but a process of transformation from simple to profound and from image to abstract. The cultivation of the concept of space depends on the observation, imagination, analysis and generalization of children. The biggest obstacle in developing the concept of space for children lies in the fact that children have “something in their eyes and invisible in their minds.” “Dynamic Imagination ” is a movement of imagination, that children according to the materials and problems provided, the existing appearance of processing, composition, imagination and the process of change and results. Behind the dynamic imagination is the children’s rich representation support, infiltrating children’s reasoning, analysis, etc., is the children’s autonomous learning of mathematics materials,
