所谓层次是物质运动由简单到复杂,由低级到高级,由量变到质变,由无序到有序,逐渐形成的类似阶梯样的程序.类似地数学思维层次性也是如此,它是进行数学活动过程中的思维,它具有惯性、顺序性和发展性.根据数学思维的特性,在具体的解题过程中,又可形成下列四个思维层次来解决问题.一、准备性层次—在大脑储备平面几何“基本信息块”程序平面几何是应用推理论证的方法研究平面图形的形状、大 The so-called level of material movement from simple to complex, from low to high, from quantitative change to qualitative change, from disorder to orderly, gradually formed a similar step-like program.Similarly the level of mathematical thinking as well, it is for mathematical activities In the process of thinking, it has inertia, order and development.According to the characteristics of mathematical thinking, in the process of solving problems, but also the formation of the following four levels of thinking to solve the problem.First, the preparatory level - in the brain reserve Plane Geometry “Basic Information Block ” Program Plane Geometry is the method of applying reasoning to demonstrate the shape of a planar graphic, large
