Mathematical thinking is understanding the nature of mathematical knowledge and methods, mathematical methods is a fundamental process of solving mathematical problems, mathematical thinking specifically reflect. So how in the teaching of mathematics penetration of mathematical methods and thinking of it? The author to talk about their understanding and awareness of the junior high school mathematics teaching in the mathematical methods and mathematical thinking.

《數(shù)學(xué)課程標(biāo)準(zhǔn)》明確指出:“教師應(yīng)激發(fā)學(xué)生的學(xué)習(xí)積極性,向?qū)W生提供充分從事數(shù)學(xué)活動(dòng)的機(jī)會(huì),幫助他們?cè)谧灾魈剿骱秃献鹘涣鞯倪^程中真正理解和掌握基本的數(shù)學(xué)知識(shí)與技能、數(shù)學(xué)思想和方法,獲得廣泛的數(shù)學(xué)活動(dòng)經(jīng)驗(yàn)”。這就要求我們要把數(shù)學(xué)思想和數(shù)學(xué)方法作為一個(gè)重要的基礎(chǔ)知識(shí)來學(xué)習(xí),作為一個(gè)優(yōu)秀的數(shù)學(xué)教師,應(yīng)該在數(shù)學(xué)教學(xué)中重視數(shù)學(xué)思想和方法的滲透,以下筆者就談?wù)劊瑢?duì)數(shù)學(xué)方法和數(shù)學(xué)思想的理解和認(rèn)識(shí)。
1何為數(shù)學(xué)方法和數(shù)學(xué)思想
所謂數(shù)學(xué)方法就是解決數(shù)學(xué)問題的基本步驟,它是數(shù)學(xué)思想的具體反映。在教學(xué)的初步階段,掌握數(shù)學(xué)方法至關(guān)重要。目前初中階段,主要數(shù)學(xué)思想方法有:數(shù)形結(jié)合思想、分類討論思想、整體思想、化歸思想、轉(zhuǎn)化思想、歸納思想、類比思想、函數(shù)思想、辯證思想、方程與函數(shù)思想方法等。所謂數(shù)學(xué)思想,就是對(duì)數(shù)學(xué)知識(shí)和方法的本質(zhì)認(rèn)識(shí),是對(duì)數(shù)學(xué)規(guī)律的理性認(rèn)識(shí)。……
