课程标准要求在“图形与几何”的学习中,建立空间观念,培养几何直观。空间想象是指根据物体特征抽象出几何图形,根据几何图形想象出所描述的实际物体;而动态想象是指想象出空间物体的方位和相互之间的位置关系;根据语言描述或通过想象画出图形等。由于以往课程中这方面内容基本空白,因此要求我们在落实课标时,必须打破传统的教学观念和方法,按照课标的新理念和新方法去实施。下面从四个方面来思考在“图形与几何教学中实施
Curriculum standards require the creation of spatial concepts in Geography and Geometry learning to develop a geometric intuition. Space imagination refers to abstracting geometric shapes according to the characteristics of objects and imagining the actual objects described according to the geometric shapes. Dynamic imagination refers to imagining the positions of the spatial objects and their positional relationship with each other; drawing graphics according to the language description or imagination Wait. Due to the basic blank of this course in the past curriculums, we are required to break the traditional teaching concepts and methods and implement them in accordance with the new concepts and new methods of the curriculums. The following four aspects to think in the ”graphics and geometry teaching
