摘要
空间观念是义务教育阶段培养学生初步的创新精神和实践能力所需要的基本要素.空间观念主要表现为学生主动、自觉或自动化地“模糊”2维和3维空间之间界限的一种本领,是一种可以把握的能力.能够发展学生空间观念的学习内容主要包括:视图与构造,直观与推理,观察与投影.通过对具体情景的探索会发现,从不同的角度观察物体、辨别方位、动手操作、想象、描述和表示、分析和推理等活动是发展学生的空间观念的有效途径.
This paper addressed the issues of why and how to increase spatial awareness through the main aspects of the National Mathematics Curriculum Standard (6-15), both in terms of curriculum development and in terms of implementation strategies. Affection would be paid to the representation of three-dimensional object in a plane and interpreting the relations between realities and photographs and drawings. This paper will also deal with the views for the necessity and possibilities to this reform.
