(一)激趣導(dǎo)入 課件出示一些圖片:師:同學(xué)們,今天老師給你們帶來了一些禮物,大家想不想知道是什么?我們一起看大屏幕:你們認(rèn)識(shí)這些物體嗎?在生活中見到過嗎?生:比薩斜塔、治安崗?fù)ぁ⒉枞~盒、客家圍屋。師:今天這節(jié)課我們重點(diǎn)來研究這些物體。(二)探究新知 1. 認(rèn)識(shí)圓柱。師:這些物體什么形狀的?它們的形狀有什么共同特點(diǎn)?生:這些物體都是圓柱形的。師小結(jié):這些物體的形狀都是圓柱體,簡(jiǎn)稱圓柱。說一說生活中有哪些圓柱形的物體。2.探究圓柱的特特征。(1)認(rèn)識(shí)底面小組活動(dòng): 觀察圓柱形物體,看看它是有幾部分組成的,有什么特征?課件演示:圓柱的上、下兩個(gè)面叫做底面,是兩個(gè)完全相同的圓。 師:請(qǐng)同學(xué)們量一量、算一算圓柱的兩個(gè)底面有什么關(guān)系?生1:兩個(gè)底面的直徑相等、半徑相等。生2:兩個(gè)底面的周長(zhǎng)相等、面積相等。師小結(jié):圓柱的底面是兩個(gè)完全相同的圓。(2)認(rèn)識(shí)側(cè)面課件演示:圓柱周圍的面叫做側(cè)面,側(cè)面是一個(gè)曲面。師:請(qǐng)同學(xué)們指一指圓柱的側(cè)面,再用手摸一摸,有什么感覺?生:側(cè)面是彎曲的。師:側(cè)面是一個(gè)曲面。
1、認(rèn)真研究教材。吃透教材是教師進(jìn)行有效課堂教學(xué)的立足點(diǎn)。除了教學(xué)的重點(diǎn),難點(diǎn)的把握,教師還應(yīng)該考慮到教材的重組與延伸?! ?、仔細(xì)推敲教學(xué)方法。隨著網(wǎng)絡(luò)的的普及,教師可以利用的資源是越來越多了,教師交流教學(xué)方法的渠道也是越來越廣,我們可以發(fā)現(xiàn)相同的教學(xué)內(nèi)容往往有多種不同的教學(xué)方法,如何選擇適合自己班級(jí)學(xué)生的教學(xué)方式在教學(xué)中有著舉足輕重的地位?! ?、有針對(duì)性的設(shè)計(jì)課堂練習(xí)。學(xué)生吸收知識(shí)第一印象往往十分重要,而教師在課堂上設(shè)計(jì)的聽說讀寫各式練習(xí)情況往往往直接影響著學(xué)生課后練習(xí)的正確率。
一、 說教材《阿西莫夫短文兩篇》是全日制普通高級(jí)中學(xué)教課書人教版八年級(jí)上冊(cè)第2單元的第2篇課文。本冊(cè)書說明文閱讀共兩個(gè)單元,可以說重在培養(yǎng)學(xué)生對(duì)說明文的閱讀、理解、分析的能力和注重觀察、講究實(shí)證的科學(xué)態(tài)度以及求真創(chuàng)新的科學(xué)精神。本單元的學(xué)習(xí)重點(diǎn)是:整體感知,注意說明的順序和方法;提高默讀的速度;能按照要求篩選信息?!栋⑽髂蚨涛膬善肥且黄湫偷目破照f明文,兩篇短文《恐龍無處不在》和《被壓扁的沙子》都有關(guān)于恐龍,但是說明的對(duì)象又有所不同,又結(jié)合班級(jí)情況和單元重點(diǎn)。在重難點(diǎn)上不必面面俱到,只是重在培養(yǎng)他們閱讀說明文的能量從而積累知識(shí)。二、說教法說明文是相當(dāng)枯燥了,因此必須抓住某一方面來提起學(xué)生的興趣。所以在教學(xué)上必須讓學(xué)生自己找到感興趣的問題加以提煉。故,在教法上我多用默讀,讓學(xué)生自己讀懂文章,在相對(duì)有難度地方采用自主、合作、探 究的方法,使學(xué)生在掌握知識(shí)的同時(shí),培養(yǎng)其閱讀說明文的能力。
一.說教材 1.教材所處的地位《慶祝奧林匹克運(yùn)動(dòng)復(fù)興25周年》是人教版部編初中語文教材八年級(jí)下冊(cè)第四單元“思想光芒”中的一篇經(jīng)典演講詞。它是同學(xué)們接觸過《 最后一次講演》《應(yīng)有格物致知精神》《我一生中的重要抉擇》,初步了解、掌握關(guān)于演講的一些技巧之后,再次讓學(xué)生傾聽那些穿越時(shí)空的聲音,感受演講精品的魅力,并總結(jié)、借鑒典范演講的經(jīng)驗(yàn),在歷練中提高演說才能。因?yàn)樵诂F(xiàn)代社會(huì)中,良好的口語交際能力是公民的重要素養(yǎng)之一,它不但顯示著一個(gè)人的語言水平,更體現(xiàn)著一個(gè)人的自信、智慧、教養(yǎng)與風(fēng)度。2.教材分析 《慶祝奧林匹克運(yùn)動(dòng)復(fù)興25周年》是顧拜旦于1919年4月在瑞士洛桑慶祝奧林匹克運(yùn)動(dòng)恢復(fù)25周年紀(jì)念會(huì)上的演說,是關(guān)于奧林匹克運(yùn)動(dòng)的重要文獻(xiàn)。顧拜旦用詩歌般的語言闡述了奧林匹克精神的內(nèi)涵與價(jià)值;以飽含喜悅的神情引領(lǐng)聽眾去聯(lián)想奧林匹克精神無限美好的前景。這篇演說詞和他的詩歌《體育頌》一起成為世界文化史和體育史上不朽的篇章。
說教材本文是部編版八年級(jí)語文下冊(cè)第五單元的第二篇課文,同時(shí)也是一篇游記。作者生動(dòng)的寫出了格拉丹東雪山的壯美,表現(xiàn)了長(zhǎng)江源頭的神異不凡。說學(xué)情學(xué)生雖然聽說過雪山,但親眼見過雪山的同學(xué)比較少。本課從紀(jì)錄片《再說長(zhǎng)江》入手,再現(xiàn)長(zhǎng)江的源頭,揭開格拉丹東雪山的神秘面紗,激發(fā)了學(xué)生求知和探索的學(xué)習(xí)欲望。教學(xué)目標(biāo)1.準(zhǔn)確認(rèn)讀并理解重點(diǎn)字詞。2.了解游記的特點(diǎn),把握作者的游蹤、寫景的角度、寫景的方法,體會(huì)格拉丹冬冰塔林的特點(diǎn)3.揣摩品味語言,欣賞、積累精彩語句。教學(xué)建議【教學(xué)方法】1.朗讀法。2.品味點(diǎn)撥法。3.合作探究法?!菊n時(shí)安排】2課時(shí)一、教學(xué)導(dǎo)入長(zhǎng)江,她以自己的源遠(yuǎn)流長(zhǎng)、磅礴大氣和她的風(fēng)光萬千,為我們構(gòu)筑了永恒的大江之美,啟發(fā)著一代又一代華夏兒女的激情與靈感,贏得了世人發(fā)自肺腑的贊美和感嘆。今天我們來學(xué)習(xí)《在長(zhǎng)江源頭各拉丹冬》這篇文章,欣賞長(zhǎng)江的源頭各拉丹冬這片雪域高原的壯美景色。
有三種購買方案:購A型0臺(tái),B型10臺(tái);A型1臺(tái),B型9臺(tái);A型2臺(tái),B型8臺(tái);(2)240x+200(10-x)≥2040,解得x≥1,∴x為1或2.當(dāng)x=1時(shí),購買資金為12×1+10×9=102(萬元);當(dāng)x=2時(shí),購買資金為12×2+10×8=104(萬元).答:為了節(jié)約資金,應(yīng)選購A型1臺(tái),B型9臺(tái).方法總結(jié):此題將現(xiàn)實(shí)生活中的事件與數(shù)學(xué)思想聯(lián)系起來,屬于最優(yōu)化問題,在確定最優(yōu)方案時(shí),應(yīng)把幾種情況進(jìn)行比較.三、板書設(shè)計(jì)應(yīng)用一元一次不等式解決實(shí)際問題的步驟:實(shí)際問題――→找出不等關(guān)系設(shè)未知數(shù)列不等式―→解不等式―→結(jié)合實(shí)際問題確定答案本節(jié)課通過實(shí)例引入,激發(fā)學(xué)生的學(xué)習(xí)興趣,讓學(xué)生積極參與,講練結(jié)合,引導(dǎo)學(xué)生找不等關(guān)系列不等式.在教學(xué)過程中,可通過類比列一元一次方程解決實(shí)際問題的方法來學(xué)習(xí),讓學(xué)生認(rèn)識(shí)到列方程與列不等式的區(qū)別與聯(lián)系.
方法總結(jié):已知解集求字母系數(shù)的值,通常是先解含有字母的不等式,再利用解集唯一性列方程求字母的值.解題過程體現(xiàn)了方程思想.三、板書設(shè)計(jì)1.一元一次不等式的概念2.解一元一次不等式的基本步驟:(1)去分母;(2)去括號(hào);(3)移項(xiàng);(4)合并同類項(xiàng);(5)兩邊都除以未知數(shù)的系數(shù).本節(jié)課通過類比一元一次方程的解法得到一元一次不等式的解法,讓學(xué)生感受到解一元一次不等式與解一元一次方程只是在兩邊都除以未知數(shù)的系數(shù)這一步時(shí)有所不同.如果這個(gè)系數(shù)是正數(shù),不等號(hào)的方向不變;如果這個(gè)系數(shù)是負(fù)數(shù),不等號(hào)的方向改變.這也是這節(jié)課學(xué)生容易出錯(cuò)的地方.教學(xué)時(shí)要大膽放手,不要怕學(xué)生出錯(cuò),通過學(xué)生犯的錯(cuò)誤引起學(xué)生注意,理解產(chǎn)生錯(cuò)誤的原因,以便在以后的學(xué)習(xí)中避免出錯(cuò).
安裝及運(yùn)輸費(fèi)用為600x+800(12-x),根據(jù)題意得4000x+3000(12-x)≤40000,600x+800(12-x)≤9200.解得2≤x≤4,由于x取整數(shù),所以x=2,3,4.答:有三種方案:①購買甲種設(shè)備2臺(tái),乙種設(shè)備10臺(tái);②購買甲種設(shè)備3臺(tái),乙種設(shè)備9臺(tái);③購買甲種設(shè)備4臺(tái),乙種設(shè)備8臺(tái).方法總結(jié):列不等式組解應(yīng)用題時(shí),一般只設(shè)一個(gè)未知數(shù),找出兩個(gè)或兩個(gè)以上的不等關(guān)系,相應(yīng)地列出兩個(gè)或兩個(gè)以上的不等式組成不等式組求解.在實(shí)際問題中,大部分情況下應(yīng)求整數(shù)解.三、板書設(shè)計(jì)1.一元一次不等式組的解法2.一元一次不等式組的實(shí)際應(yīng)用利用一元一次不等式組解應(yīng)用題關(guān)鍵是找出所有可能表達(dá)題意的不等關(guān)系,再根據(jù)各個(gè)不等關(guān)系列成相應(yīng)的不等式,組成不等式組.在教學(xué)時(shí)要讓學(xué)生養(yǎng)成檢驗(yàn)的習(xí)慣,感受運(yùn)用數(shù)學(xué)知識(shí)解決問題的過程,提高實(shí)際操作能力.
把解集在數(shù)軸上表示出來,并將解集中的整數(shù)解寫出來.解析:分別計(jì)算出兩個(gè)不等式的解集,再根據(jù)大小小大中間找確定不等式組的解集,再找出解集范圍內(nèi)的整數(shù)即可.解:x+23<1?、?,2(1-x)≤5 ②,由①得x<1,由②得x≥-32,∴不等式組的解集為-32≤x<1.則不等式組的整數(shù)解為-1,0.方法總結(jié):此題主要考查了一元一次不等式組的解法,解決此類問題的關(guān)鍵在于正確解得不等式組或不等式的解集,然后再根據(jù)題目中對(duì)于解集的限制得到下一步所需要的條件,再根據(jù)得到的條件進(jìn)而求得不等式組的整數(shù)解.三、板書設(shè)計(jì)一元一次不等式組概念解法不等式組的解集利用數(shù)軸確定解集利用口訣確定解集解一元一次不等式組是建立在解一元一次不等式的基礎(chǔ)之上.解不等式組時(shí),先解每一個(gè)不等式,再確定各個(gè)不等式組的解集的公共部分.
教學(xué)目標(biāo):1.知道二次函數(shù)與一元二次方程的聯(lián)系,提高綜合解決問題的能力.2.會(huì)求拋物線與坐標(biāo)軸交點(diǎn)坐標(biāo),會(huì)結(jié)合函數(shù)圖象求方程的根.教學(xué)重點(diǎn):二次函數(shù)與一元二次方程的聯(lián)系.預(yù)設(shè)難點(diǎn):用二次函數(shù)與一元二次方程的關(guān)系綜合解題.☆ 預(yù)習(xí)導(dǎo)航 ☆一、鏈接:1.畫一次函數(shù)y=2x-3的圖象并回答下列問題(1)求直線y=2x-3與x軸的交點(diǎn)坐標(biāo); (2)解方程2x-3=0(3)說出直線y=2x-3與x軸交點(diǎn)的橫坐標(biāo)和方程根的關(guān)系2.不解方程3x2-2x+4=0,此方程有 個(gè)根。二、導(dǎo)讀畫二次函數(shù)y= x2-5x+4的圖象1.觀察圖象,拋物線與x軸的交點(diǎn)坐標(biāo)是什么?2.求一元二次方程x2-5x+4=0的解。3.拋物線與x軸交點(diǎn)的橫坐標(biāo)與一元二次方程x2-5x+4=0的解有什么關(guān)系?(3)一元二次方程ax2+bx+c=0是二次函數(shù)y=ax2+bx+c當(dāng)函數(shù)值y=0時(shí)的特殊情況.二次函數(shù)y=ax2+bx+c的圖象與x軸交點(diǎn)的橫坐標(biāo)與一元二次方程ax2+bx+c=0的根有什么關(guān)系?
解:(1)設(shè)第一次落地時(shí),拋物線的表達(dá)式為y=a(x-6)2+4,由已知:當(dāng)x=0時(shí),y=1,即1=36a+4,所以a=-112.所以函數(shù)表達(dá)式為y=-112(x-6)2+4或y=-112x2+x+1;(2)令y=0,則-112(x-6)2+4=0,所以(x-6)2=48,所以x1=43+6≈13,x2=-43+6<0(舍去).所以足球第一次落地距守門員約13米;(3)如圖,第二次足球彈出后的距離為CD,根據(jù)題意:CD=EF(即相當(dāng)于將拋物線AEMFC向下平移了2個(gè)單位).所以2=-112(x-6)2+4,解得x1=6-26,x2=6+26,所以CD=|x1-x2|=46≈10.所以BD=13-6+10=17(米).方法總結(jié):解決此類問題的關(guān)鍵是先進(jìn)行數(shù)學(xué)建模,將實(shí)際問題中的條件轉(zhuǎn)化為數(shù)學(xué)問題中的條件.常有兩個(gè)步驟:(1)根據(jù)題意得出二次函數(shù)的關(guān)系式,將實(shí)際問題轉(zhuǎn)化為純數(shù)學(xué)問題;(2)應(yīng)用有關(guān)函數(shù)的性質(zhì)作答.
方法總結(jié):絕對(duì)值小于1的數(shù)也可以用科學(xué)記數(shù)法表示,一般形式為a×10-n,其中1≤a<10,n為正整數(shù).與較大數(shù)的科學(xué)記數(shù)法不同的是其所使用的是負(fù)整數(shù)指數(shù)冪,指數(shù)由原數(shù)左邊起第一個(gè)不為零的數(shù)前面的0的個(gè)數(shù)所決定.【類型二】 將用科學(xué)記數(shù)法表示的數(shù)還原為原數(shù)用小數(shù)表示下列各數(shù):(1)2×10-7; (2)3.14×10-5;(3)7.08×10-3; (4)2.17×10-1.解析:小數(shù)點(diǎn)向左移動(dòng)相應(yīng)的位數(shù)即可.解:(1)2×10-7=0.0000002;(2)3.14×10-5=0.0000314;(3)7.08×10-3=0.00708; (4)2.17×10-1=0.217.方法總結(jié):將科學(xué)記數(shù)法表示的數(shù)a×10-n還原成通常表示的數(shù),就是把a(bǔ)的小數(shù)點(diǎn)向左移動(dòng)n位所得到的數(shù).三、板書設(shè)計(jì)用科學(xué)記數(shù)法表示絕對(duì)值小于1的數(shù):一般地,一個(gè)小于1的正數(shù)可以表示為a×10n,其中1≤a<10,n是負(fù)整數(shù).從本節(jié)課的教學(xué)過程來看,結(jié)合了多種教學(xué)方法,既有教師主導(dǎo)課堂的例題講解,又有學(xué)生主導(dǎo)課堂的自主探究.課堂上學(xué)習(xí)氣氛活躍,學(xué)生的學(xué)習(xí)積極性被充分調(diào)動(dòng),在拓展學(xué)生學(xué)習(xí)空間的同時(shí),又有效地保證了課堂學(xué)習(xí)質(zhì)量
