观察是人们获取信息、发现问题和解决问题的前提.在数学学习中,要进行猜测、验证、推理与交流,首先要进行观察.在平时教学中,要注意培养学生从各个不同的侧面去观察事物、考虑问题,用精确的语言和数学符号准确表达观察的结果.一个问题的条件与所求结论之间会存在着各种联系,通过观察找到这些联系,构建已知与未知之间的桥梁,就能由已知通向未知.二要观察问题中的隐含条件.正确找出与所求结论之间有隐含关系的条件是解题的切入点和成功解题的关键.三要
Observation is a prerequisite for people to obtain information, find out the problem and solve the problem.In mathematics study, we should conduct the observation, the verification, the reasoning and the communication.We should pay attention to cultivate the students from different aspects to observe Things, consider the problem, accurate language and mathematical symbols to accurately express the results of the observation.A problem of the conditions and the conclusion will be the existence of all kinds of connections, through the observation of these links to build a bridge between known and unknown , We can know from the unknown to the unknown. Second, we must observe the implicit conditions of the problem. Correctly find the implicit relationship with the conclusion of the conditions required is the starting point for solving the problem and the key to successful problem solving.
