小学数学教材中的“空间与图形”主要是研究现实世界中的物体和几何图形的大小、形状、位置关系及其变换,它能够有效地帮助小学生认识生活空间。在“空间与图形”的教学过程中,教师使用一些教学方法能帮助学生进一步观察、理解、操作、交流、探究空间中的图形的位置、大小变化,从而不断发展和锻炼学生的空间想象能力和逻辑思维能力。因此,教师应该积极探究有效的教学方法,通过科学合理的教学手段,让学生在生活情境中感知图形的特征,了解空间图形的基本构成,通过动手实践让学生获取对图形的认知,让学生形成空间观念,提升学生在学习“空间与图形”中的探究学习能力,培养学生的想象能力和认知能力。
Primary school mathematics textbooks “space and graphics ” is mainly to study the size, shape, location and transformation of objects and geometric shapes in the real world, which can effectively help pupils understand the living space. In the process of teaching “Space and Graphics”, teachers use some teaching methods to help students further observe, understand, operate, communicate and explore the position and size of the graphics in the space so as to continuously develop and train students’ space imagination Ability and logical thinking ability. Therefore, teachers should actively explore effective teaching methods, through scientific and reasonable teaching methods, let students perceive the characteristics of graphics in the context of life, to understand the basic composition of the spatial graphics, through practical hands-on so that students gain access to the graphics, so that students Form the concept of space, enhance students ’learning abilities in learning “space and graphics”, and develop students’ imagination and cognitive abilities.
