所谓空间观念,是指人们对客观事物、几何形体的形状、大小、位置以及它们之间的变化、关系和基本结构在头脑中形成的概括化的形象,是数学十大学科核心素养之一。那么在数学学习中应该怎样去培养学生的空间观念,将“致力于空间观念的建立”这一理念切实转化为有效的教学行为?我们结合二年级学生形象思维优于 The so-called space concept refers to people’s objective things, the geometry of the shape, size, location and changes among them, the relationship between the basic structure of the formation of a generalized image of the mind, is one of the core qualities of the top ten disciplines. So in mathematics learning how to cultivate the concept of space students, the concept of “committed to the establishment of space concept” effectively translated into effective teaching behavior? We combine the image of second grade students better than thinking
