数学教学中的观察,就是有意识地对事物的数和形的特点进行感知,即对符号、字母、数字或文字所表示的关系式、命题、几何图形的结构特点进行察看。此举,可以认识数学的内涵、抽象概括数学定理及数学模型。因此教学中必须重视学生观察能力的培养。一、激发浓厚观察兴趣的方法一是以美引趣。图形所展现的外在形式的美、抽象概括所体现的简单统一内在的美、数量关系与空间形式所呈
The observation in mathematics teaching is to perceive the number and shape of things consciously, that is, the structural features of the relations, propositions and geometrical figures represented by symbols, letters, numbers or words. This move can recognize the connotation of mathematics, abstract mathematical theorems and mathematical models. Therefore, teaching must attach importance to the cultivation of students' observation skills. First, stimulate the observation of a strong interest in the first method is to attract interest. The beauty of the external forms exhibited by the figures, the simple unification of the intrinsic beauty, the quantitative relations and the spatial forms embodied in the abstract generalizations
