观察是事物在人脑的直接反映,是一种主动、积极的思维活动。因为,观察可以在对事物进行分析、比较、抽象、概括过程中透过现象看到事物的内部联系和事物的本质。《义务教育全日制初级中学数学指导纲要》指出:学生在初中数学学习阶段,应该具备处理数据的运算能力、识别图形的空间想象能力和逻辑思维能力、掌握基本的数量关系和图形相关基础知识。如果不能很好地培养学生的观察能力,初中生就不能具备完整的数学能力与数学素养,数学教学的目标也不能真正实现,因此,如何培养学生的观察能力是初中数学教师十分关注的问题。
Observation is a direct reflection of things in the human brain, is a kind of active and positive thinking activities. Because observation can observe the internal relations of things and the essence of things through phenomena in the process of analyzing, comparing, abstracting and summarizing things. The compulsory education full-time junior high school mathematics instruction outline points out: Students in the junior high school mathematics learning stage should have the ability to handle data, identify the graphics space imagination ability and logical thinking ability, master the basic quantitative relationship and graphics-related basic knowledge. If you can not develop students ’observation ability well, junior high school students can not have complete math ability and maths accomplishment, and the goal of math teaching can not be truly realized. Therefore, how to cultivate students’ abilities of observing is a matter of great concern to junior math math teachers.
