小学几何初步知识教学最重要任务就是培养学生的空间观念。空间观念是在空间知觉的基础上形成的,是几何形体的大小、形状及其位置关系在人脑中表象。由于空间观念的积累,可以逐步形成空间想象力,这将为目前和以后的学习奠定必要的基础。那么,如何在“空间和图形”的教学中发展学生空间观念呢?个人有几点想法。建立空间观念。观察是一种有目的、有顺序、持久的视觉活动,是小学生获得初步空间观念的主要途径之一。《数学课堂标
The primary task of elementary geometry teaching in elementary school is to cultivate students’ concept of space. The concept of space is formed on the basis of spatial perception. It is the representation of the size, shape and location of the geometry in the human brain. Due to the accumulation of space concept, spatial imagination can be gradually formed, which will lay the necessary foundation for current and future learning. So, how to develop the concept of student space in the teaching of “space and graphics”? There are several personal ideas. Create a space concept. Observation is a purposeful, orderly and lasting visual activity, which is one of the main ways for primary school students to acquire the initial space concept. Mathematical classroom standard
