在数学学习中,观察是一种很重要的思维活动.要想学好数学,首先要学会观察.观察的对象可分为两类:一类是用符号(数字、字母、运算符号、关系式)或文字所表示的数学关系式,命题或问题;另一类是几何图形、图象及图表.观察是一项有序的思维活动,不能眉毛胡子一把抓.否则,观察就起不到真正的作用,反而会带会负面效应.为了提高观察的效率,在教学过程中,教师应引导学生掌握科学的观察方法.通常的观察方法可有以下几类1 整体观察 在教学过程中,有的学生往往只观察到问题的一个方面而忽视整体.从而无法下手解决问题.任何一个事物,都存在整体与部分的关系.在进行数学观察时,观察整体的同时,还必须观察其部分的特
In mathematics learning, observation is a very important thinking activity. If you want to learn mathematics, you must first learn to observe. Observed objects can be divided into two categories: one is the use of symbols (numbers, letters, operators, relations) Or mathematical relations, propositions or questions expressed in words; the other is geometric figures, images and charts. Observation is an orderly thinking activity and cannot be grasped by the eyebrows and mustaches. Otherwise, observation will not be of any real effect. Instead, it will bring about negative effects. In order to improve the efficiency of observation, teachers should guide students in the teaching process to master the scientific observation methods. The usual observation methods can be the following types. 1 Overall observation in the teaching process, and some students often Only one aspect of the problem is observed and the whole is ignored. Thus, it is impossible to solve the problem. There is a relationship between the whole and the part in any one thing. When observing the whole while observing the mathematics, we must also observe its part.
