空间主要研究客观世界中物体的几何属性,而空间观念则是在空间知觉基础上形成的大脑表象,对于进一步认识和改造客观世界具有非常重要的意义。新课标明确提出,要加强对小学生空间观念的发展和培养,进行数学思想方法的引导,用数学思维构建世界模型。那么如何培养学生的空间观念呢?通过教学实践摸索与探究,笔者认为可以从以下几个方面进行。一、重视识图画图,深化空间表象
Space mainly studies the geometric properties of objects in the objective world. Space concepts are brain representations formed on the basis of spatial perception, which is of great significance for further understanding and transformation of the objective world. The new curriculum clearly put forward to strengthen the concept of primary school space for the development and training of mathematical thinking and guidance to build a mathematical model of the world model. So how to cultivate students’ concept of space? Through exploration and exploration of teaching practice, I believe that from the following aspects. First, pay attention to drawing pictures, deepen the appearance of space
