“先入为主,思维定势”是很多学生在解题中存在的普遍现象。由于这一现象,使得一些学生思维得不到很好发展、解题能力得不到提高。在数学解题中,如果能展开联想思维,往往能受到事半功倍的效果。何谓联想思维?就是指根据数学问题的不同特点,有针对性地展开类似联想、相反联想或接近联想,就联想的方法和内容看,有的可联想有关的定义和法则,有的可联想常用的数学方法和一些已经研究过的数学问题,常常能打开我们的思路,发散我们的 “Preconception, thinking set ” is a common phenomenon many students in the problem-solving. Due to this phenomenon, some students are not thinking well and their ability to solve problems can not be improved. In mathematics problem solving, if you can start associative thinking, you can often get a multiplier effect. What is associative thinking? It refers to the different characteristics of mathematical problems, targeted to start a similar association, on the contrary Lenovo or close to Lenovo, Lenovo’s methods and content to see, some may be related to the definition of the relevant laws and regulations, Mathematical methods and some mathematical problems that have been studied often open our minds and diverge our
