“數(shù)的運(yùn)算”是“數(shù)與代數(shù)”學(xué)習(xí)領(lǐng)域的重要內(nèi)容，減法是其中的一種基本運(yùn)算．本課的學(xué)習(xí)遠(yuǎn)接小學(xué)階段關(guān)于整數(shù)、分?jǐn)?shù)（包括小數(shù)）的減法運(yùn)算，近承第四節(jié)有理數(shù)的加法運(yùn)算．通過(guò)對(duì)有理數(shù)的減法運(yùn)算的學(xué)習(xí)，學(xué)生將對(duì)減法運(yùn)算有進(jìn)一步的認(rèn)識(shí)和理解，為后繼諸如實(shí)數(shù)、復(fù)數(shù)的減法運(yùn)算的學(xué)習(xí)奠定了堅(jiān)實(shí)的基礎(chǔ)．鑒于以上對(duì)教學(xué)內(nèi)容在教材體系中的位置及地位的認(rèn)識(shí)和理解，確定本節(jié)課的教學(xué)目標(biāo)如下：1、知識(shí)目標(biāo)：經(jīng)歷探索有理數(shù)的減法法則的過(guò)程，理解有理數(shù)的減法法則，并能熟練運(yùn)用法則進(jìn)行有理數(shù)的減法運(yùn)算．2、能力目標(biāo)：經(jīng)歷由特例歸納出一般規(guī)律的過(guò)程，培養(yǎng)學(xué)生的抽象概括能力及表達(dá)能力；通過(guò)減法到加法的轉(zhuǎn)化，讓學(xué)生初步體會(huì)轉(zhuǎn)化、化歸的數(shù)學(xué)思想．3、情感目標(biāo)：
北師大版初中數(shù)學(xué)九年級(jí)下冊(cè)切線(xiàn)長(zhǎng)定理說(shuō)課稿
通過(guò)與學(xué)生講解切線(xiàn)長(zhǎng)定義，讓學(xué)生在參與、合作中有一個(gè)猜想，再進(jìn)一步提出更有挑戰(zhàn)性的問(wèn)題，能否用數(shù)學(xué)的方法加以證明。問(wèn)題的解決，使學(xué)生既能解決新的問(wèn)題，同時(shí)應(yīng)用到全等、切線(xiàn)的性質(zhì)等知識(shí)，同時(shí)三條輔助線(xiàn)中，兩條運(yùn)用切線(xiàn)性質(zhì)添加、一條構(gòu)造全等。證明后用較規(guī)范的語(yǔ)言歸納并不斷完善。（3） 應(yīng)用新知加深理解通過(guò)前面的學(xué)習(xí)學(xué)生們已經(jīng)對(duì)切線(xiàn)長(zhǎng)定理有了較深刻的了解。為了加深學(xué)生對(duì)定理的認(rèn)識(shí)并培養(yǎng)學(xué)生的應(yīng)用意識(shí)學(xué)習(xí)例1、例2。例1讓學(xué)生自己獨(dú)立完成，加深對(duì)切線(xiàn)長(zhǎng)定理的理解，老師進(jìn)行點(diǎn)評(píng)，對(duì)于例2，由師生共同分析完成，交進(jìn)行示范板書(shū)。（4） 鞏固與提高此訓(xùn)練題分為二個(gè)層次，目的在于鞏固新學(xué)的定理，并將所學(xué)的定理應(yīng)用到舊的知識(shí)體系中，使學(xué)生的知識(shí)體系得到補(bǔ)充和完善。（5） 歸納與小結(jié)通過(guò)小結(jié)，使知識(shí)成為系統(tǒng)幫助學(xué)生全面理解，掌握所學(xué)的知識(shí)。
