2、聯(lián)系。一方面,借助于圖形的性質(zhì)可以將許多抽象的數(shù)學(xué)概念和數(shù)量關(guān)系形象化、簡(jiǎn)單化,給人以直覺(jué)的啟示。另一方面,將圖形問(wèn)題轉(zhuǎn)化為代數(shù)問(wèn)題,以獲得精確的結(jié)論。因此,數(shù)形結(jié)合不應(yīng)僅僅作為一種解題方法,而應(yīng)作為一種十分重要的數(shù)學(xué)思想方法,它可以拓寬學(xué)生的解題思路,提高他們的解題能力,將它作為知識(shí)轉(zhuǎn)化為能力的“橋”。關(guān)鍵詞:數(shù)形結(jié)合思想;直觀;數(shù)學(xué)教學(xué);應(yīng)用Discussesthenumbershapeunionthoughtshallowlyintheteaching11河南教育學(xué)院本科畢業(yè)論文(設(shè)計(jì))applicationWangyang(DepartmentofM
