空间观念主要是指根据物体特征抽象出几何图形,根据几何图形想象出所描述的实际物体;想象出物体的方位和相互之间的位置关系;描述图形的运动和变化;依据语言的描述画出图形等。建立空间观念的过程是一个基于观察、想象、比较、分析、综合、抽象、概括,由浅入深地认识客观事物的过程,同时也是在对周围环境直观感知的基础上,理解空间与平面之间关系的过程。学生首先接触到的现实世界都是立体的,平面图形是附着在立体上的。教材按照“立体图形—平面图形—立体图形”的顺序编排知识体系,是符合
The concept of space mainly refers to abstracting geometric figures according to the characteristics of objects, imagining the actual objects described according to the geometric figures, imagining the orientations of the objects and their positional relationship with each other, describing the movements and changes of the figures, drawing the figures according to the description of the language Wait. The process of establishing the concept of space is a process of understanding objective things based on observation, imagination, comparison, analysis, synthesis, abstraction and generalization, and also on the basis of intuitive perception of the surrounding environment, understanding the relationship between space and plane Relationship process. The first real world students come into contact with are three-dimensional, graphic graphics are attached to the three-dimensional. Textbook in accordance with the “three-dimensional graphics - graphic - three-dimensional graphics,” the order of the knowledge system, is in line with
