“图形与几何”是小学数学课程内容的重要组成部分,其核心目标在于发展学生的空间观念,培养空间思维能力。那么,如何通过具体的教学实践将先进理念与课程目标有机结合,以促进学生空间思维的发展?现以几个教学片断为例,浅谈在小学数学教学中小学生空间思维的培养。一、注重直观感知,形成思维表象皮亚杰的认知发展理论指出:“儿童空间观念的演化是在知觉水平和思维水平上进行的。”空间知觉是空间思维发展的起点。儿童通过观察、操作等直观感知,可以建立起大脑对空间特性的表征,是形成空间思维的基础。
“Graphics and Geometry ” is an important part of the elementary mathematics curriculum content. Its core goal is to develop the students’ space concept and cultivate the space thinking ability. So, how to combine the advanced idea with the goal of the curriculum through concrete teaching practice so as to promote the development of students ’space thinking? Take a few teaching pieces as an example to discuss the cultivation of primary school students’ space thinking in primary mathematics teaching. First, focus on intuitive perception, the formation of thinking Piaget’s cognitive development theory pointed out: “The evolution of children’s space concept is carried out in the perception level and thinking level. ” Spatial perception is the starting point of the development of spatial thinking. Children through the observation, operation and other intuitive perception, can establish the characterization of the brain space characteristics, is to form the basis for spatial thinking.
