宏观元素,是指几何图形中的背景图形或概念中的主体;微观元素是指构成宏观图形的各个子图形——隐含在其中的基本图形或概念中的修饰语.在数学学习中,学生经常出现概念辨析不准、几何证明分析不出的情况,我们可以把原因归结为学生没有很好地把握数学概念和几何图形中的“宏观元素”和“微观元素”。将从代数概念教学的“宏观微观分析法”、挖掘几何图形中的宏观元素与微观元素、图形运动中的“宏观化”和“微观化”以及几何概念中的宏观元素与微观元素等方面例谈在初中数学教学中的探索与尝试。
Macroscopic elements refer to the subject in a background graphic or concept in a geometric graphic; the micro-graphic elements are the basic graphic or conceptual modifiers implicated in the various sub-graphic forms that form the macroscopic graphic. In mathematical learning, a student Often the concept of discrimination is not allowed, the geometric proof of the situation can not be analyzed, we can put the reason can be attributed to the students do not properly grasp the concept of mathematics and geometry “macro element ” and “micro element ”. From the macroscopic microanalysis method of algebraic concept teaching, the macro elements and micro elements in geometrical figures, macroscopic elements and microinarges in graphic motions and macroscopic elements in geometric concepts Examples of Microelements and Other Examples Exploration and Attempt in Junior Mathematics Teaching.
