摘要:當(dāng)一個數(shù)學(xué)問題擺在我們面前的時候,一系列的設(shè)想便接連而來:已知條件是什么?目標(biāo)是什么?有些什么特點?該問題與哪些知識有關(guān)?是否知道與此題相關(guān)的問題等等??v觀數(shù)學(xué)解題,不難看出“類比法”是一種常用的解題方法。本文將對在解題過程中常用的五方面的類比:對比類比、類比構(gòu)造、簡化類比、辯證類比和正反類比進(jìn)行闡述,并舉例說明。 關(guān)鍵詞: 類比 類比法 數(shù)學(xué)解題 解題方法
[Abstract] When a mathematical problem before us, a range of ideas from Doomsday : known what conditions? What is the objective? What characteristics? The issues with which knowledge? Aware of this issue and related issues, and so on. Taking a panoramic view of mathematical problem solving, it is easy to see the "analogy" is a common problem-solving approach. This paper will be in the process of problem solving used in the five analogy to explain and illustrate. They are comparative analogy, analogous structure, simplify analog, and the positive and negative Syndrome analogy analogy [Key words] : analog analogy solving mathematical problem-solving methods
“類比是一個偉大的引路人”(波利亞)“每當(dāng)理智缺乏可靠論證的思路時,類比這個方法往往能指引我們前進(jìn)”(康德)[ 1 ] 在新問題面前很自然的追憶過去,把解決某個問題的原則、方法“移植”過來,在解決舊問題的啟發(fā)下,而獲得解決新問題的方法,這種解題方法叫做類比法。 類比在數(shù)學(xué)解題中有著十分重要的作用,類比推理可用如下圖示描述: |
