我们经常遇到这样的现象:对于某一问题无论怎么想,都无法解决,但是有一天由于做别的题目,而突然联想到原来的问题,从而使问题迎刃而解.这就是联想的作用.联想是思维的深化,它寓于思维过程中,是由一种信息情景思索到另一种信息情景的心理现象,在认识活动中起着桥梁作用.在数学解题中,只有学会联想,才能顺利沟通条件与结论之间的必然联系,用熟悉的知识或方法去解决陌生的问题. We often encounter such a phenomenon: no matter what you think about a problem, you can not solve it, but one day due to do other problems, and suddenly think of the original problem, so that the problem is solved .This is the role of association.Lenovo The deepening of thinking, which lies in the thinking process, is a mental phenomenon of thinking from one information scene to another information scene, which plays a bridge role in cognitive activities.In mathematics problem solving, only by learning association can the conditions be communicated smoothly And the inevitable connection between the conclusions, with familiar knowledge or method to solve strange problems.
