数学家拉普拉斯也说过:“甚至在数学里,发现真理的主要工具也是归纳和类比。”类比是根据两个对象之间在某些方面的相同或相似,从而推出它们在其他方面也可能相同或相似。类比法是初中重要的教学方法,在科学发展中占有十分重要的地位,数学中的许多定理、公式和法则是通过类比得到的,在解题中寻找问题的线索,往往也借助于类比方法,从而达到启发思路的目的。本文想围绕类比法,从一个故事、两个关键点、三大作用来漫谈。
The mathematician Laplace also said: “Even in mathematics, the main tool for discovering truth is induction and analogy.” "Analogies are based on the sameness or similarity between two objects in some respects, so they are introduced Other aspects may be the same or similar. Analogy is an important teaching method in junior high school and occupies a very important position in the scientific development. Many theorems, formulas and laws in mathematics are obtained through analogy. Clues to find problems in problem solving are often based on analogy, So as to achieve the purpose of inspiring ideas. This article wants to focus on analogy, from a story, two key points, the three major roles to talk about.
