初中生从学习代数转到学习几何,对学生来说是学习数学的一个转折,由于研究对象发生了变化,从研究客观世界的量与量的关系转到主要研究客观世界的空间形式;几何图形的性质是用定义、定理的形式进行描述的,表达方式和研究方法是严格的推理论证,要求有一定逻辑思维能力和心理适应过程。如果学生心理准备不足,就会遇到困难,容易导致两极分化。因此,要做好以下几方面。一、要实现几个方面的转变1.从一般语言到几何语言。词语是表达思维和概念的符号,几何的定义、定理除了使用一般语言外,还要使用精确、严
Junior high school students from learning algebra to learning geometry, is a turning point for students learning mathematics, because the research object has changed from the study of the relationship between quantity and quantity of the objective world to the main study of the spatial form of the objective world; geometry Is described in the form of definition and theorem. The way of expression and the method of research are rigorous reasoning and argumentation, which requires certain logical thinking ability and psychological adaptation process. If students are not mentally prepared, they will encounter difficulties and easily lead to polarization. Therefore, to do the following aspects. First, to achieve several aspects of change 1. From general language to geometric language. Words are the symbols that express ideas and concepts. The definition of geometry, in addition to using general language, must be precise and strict
