一、明確目標(biāo)1.引導(dǎo)學(xué)生熟讀課文,理清文章的論述線索,抓住作者的主要觀點(diǎn);2.通過學(xué)習(xí),了解有關(guān)數(shù)學(xué)文化的一些知識(shí);3.引導(dǎo)學(xué)生悉心體會(huì)作者對(duì)數(shù)學(xué)源頭的溯訪,感受其令人信服的推理能力和獨(dú)特的語言魅力;二、整體感知1.導(dǎo)入新課"屈指可數(shù)""彈指一揮見",手指在生活中的計(jì)數(shù)功能,直接催生了數(shù)學(xué)這門科學(xué),丹齊克的《指印》為我們揭開了這二者的關(guān)系(板書課題)。2.作者及相關(guān)背景介紹丹齊克(1884-1956),原籍立陶宛,曾在巴黎大學(xué)求學(xué)。1910年去美國,入美國國籍,先后在哥倫比亞大學(xué)、約翰·霍普金斯大學(xué)、馬里蘭大學(xué)講授數(shù)學(xué)。三、重點(diǎn)、難點(diǎn)的學(xué)習(xí)與目標(biāo)達(dá)成過程1.感知課文,明確本文的整體寫作思路。(1)學(xué)生讀課文,整理文章的結(jié)構(gòu)脈絡(luò)。(2)小組交流討論。
節(jié)選部分結(jié)構(gòu):節(jié)選自第二幕,主要寫周樸園與魯家母子的對(duì)話,分兩部分。第一部分:三十年后周樸園和侍萍再次相見。第一層:侍萍以敘述別人故事的口吻,揭露周樸園的罪惡,訴說自己的遭遇。──寫他們過去的矛盾第二層:通過周樸園態(tài)度的變化,暴露他的偽善面目,表現(xiàn)侍萍這個(gè)勞動(dòng)?jì)D女的階級(jí)本色。──寫他們現(xiàn)在的矛盾第二部分:周樸園與魯大海父子、侍萍與周萍母子見面。通過周樸園和魯大海的激烈沖突,揭露周樸園壓榨工人的罪行,反映工人階級(jí)的反抗斗爭(zhēng)。分段依據(jù):第一部分從家庭生活方面來揭露周樸園;第二部分從社會(huì)生活方面來揭露周樸園。為了使周魯兩家三十年的新仇舊恨集中在一幕戲中得到反映,作者靈活地運(yùn)用了“回顧”的方法,把歷史和現(xiàn)實(shí),過去和現(xiàn)在緊緊聯(lián)系起來了,用以刻畫人物性格,推動(dòng)劇情發(fā)展。
羅森塔爾突破了“客觀報(bào)道”“零度寫作”的框框,把自己和其他參觀者在奧斯維辛訪問時(shí)的感受當(dāng)做文章的主要內(nèi)容來寫,傳達(dá)出每一個(gè)良知者的共同心聲。教師總結(jié):細(xì)節(jié)描寫是耐人尋味的。文章沒有陰森恐怖的鏡頭,沒有血腥的畫面,只是重現(xiàn)了新聞的事實(shí)真相,但透過細(xì)節(jié)卻能引發(fā)人們對(duì)生命,對(duì)人性的思考。在作者看似平靜的敘述中抒發(fā)了對(duì)德國納粹殘酷暴行的沉重控訴,更表達(dá)了作者對(duì)自由、和平與祥和的向往四、拓展延伸:《奧斯維辛沒有什么新聞》這一作品本身的價(jià)值在哪?社會(huì)價(jià)值又在哪,能不能從這兩個(gè)角度思考,幾人合作試寫一段頒獎(jiǎng)詞?范例:《奧斯維辛沒有什么新聞》突破新聞“零度寫作”原則,著眼細(xì)節(jié),以冷峻的視角,深沉地描述了今天的奧斯維辛集中營紀(jì)念館。在恐怖與快樂、戰(zhàn)爭(zhēng)與和平、歷史與現(xiàn)實(shí)的反差中,它召喚起人們關(guān)于災(zāi)難的記憶、關(guān)于生命的思考、關(guān)于人性的自省。它的發(fā)表充分地表現(xiàn)了一個(gè)新聞?dòng)浾叩氖姑?,更以迫人的力量震撼生者的心,成為新聞史不朽的名篇?/p>
Knowledge objectives:(1) to make Ss grasp the usage of words, expressions and sentence structures: statistics, struggle, thanks to, rid of, some patterns for persuasion, the “ing” form as subject and object;(2)to use learnt knowledge to persuade sb.Ability objectives:(1) to develop Ss’ reading skills(skimming, scanning, word guessing);(2) to improve Ss’ speaking, communicating and cooperating skills.Emotional objectives:to make Ss know the contribution of Yuan,and learn his spirit and his simple life time.Teaching important and difficult points:(1) some words, expressions and sentence structures mentioned above;(2)the content of the text;(3)training their reading and speaking skills.Teaching methods: CLT, TBLT,QT.Learning strategies: CLS, QLS, TBLS.Teaching procedures:Step 1 lead-in: (1) teacher plays a piece of recent news from CCTV about the harvest of the super hybrid rice, and ask students whether they know Yuan or not, and talk about him and his contribution.(2)Brain storm: let Ss describe Yuan in their minds including his appearance, his living condition and so on.Step 2 fast reading tasks:(1)teacher introduces Yuan and super hybrid rice(2)make Ss read the text as fast as possible with questions.

在接下來的細(xì)讀環(huán)節(jié),我套用了高考對(duì)閱讀理解的考查方式設(shè)置了5個(gè)問題,分別為三個(gè)推理判斷題,一個(gè)細(xì)節(jié)題和一個(gè)主旨大意題。學(xué)生需要對(duì)文章的內(nèi)容進(jìn)行分析、歸納、推理、猜測(cè)等高級(jí)思維活動(dòng)才能做出正確的回答?!驹O(shè)計(jì)意圖】這一過程是對(duì)學(xué)生進(jìn)行細(xì)讀的訓(xùn)練,培養(yǎng)學(xué)生獲取特定信息和挖掘文章深層次信息的能力。第三環(huán)節(jié):Intensive-reading (精讀) 15′第三個(gè)環(huán)節(jié)精讀,既是最重要的環(huán)節(jié),也是突破本課重難點(diǎn)的關(guān)鍵。首先,讓學(xué)生思考劇本中人物看到百萬英鎊前后的態(tài)度發(fā)生了怎樣的變化。其次,讓學(xué)生仔細(xì)閱讀文章,找出可以表現(xiàn)人物態(tài)度變化的具體的語言和動(dòng)作。最后,讓學(xué)生總結(jié)人物的態(tài)度發(fā)生變化的根本原因是什么,從而引出Money Talks, 供學(xué)生思考?!驹O(shè)計(jì)意圖】通過一系列的活動(dòng)培養(yǎng)學(xué)生學(xué)習(xí)從人物的語言和動(dòng)作探究人物的心理,使學(xué)生進(jìn)一步體會(huì)戲劇語言的魅力,從而對(duì)文章背后所反映的社會(huì)問題進(jìn)行思考,也為下一步的討論環(huán)節(jié)做好鋪墊。
今天我們來介紹一下必修五第四單元的授課方式。這個(gè)單元的題目是Making the news。應(yīng)該是學(xué)生比較感興趣的話題,學(xué)生往往對(duì)新聞工作充滿好奇,所以我們可以利用這個(gè)機(jī)會(huì)多設(shè)計(jì)一些師生互動(dòng)和學(xué)生互動(dòng),來激發(fā)起學(xué)習(xí)的積極性,提高學(xué)習(xí)效率。同時(shí)我們可以利用這個(gè)單元不僅幫助學(xué)生掌握語言知識(shí),培養(yǎng)語言能力,同時(shí)讓其了解新聞工作的重要性,培養(yǎng)起社會(huì)智能感。這個(gè)單元分為六個(gè)課時(shí),它的教學(xué)目標(biāo)是這樣的:語言目標(biāo)是掌握詞匯表中的常用單詞和短語,掌握倒裝句的一些基本用法。 技能目標(biāo)是能初步掌握約會(huì)的基本句型并在真實(shí)的場(chǎng)景下正確運(yùn)用。新聞報(bào)道類文章的寫作技能。采訪的基本規(guī)范和溝通技能。情感目標(biāo)是對(duì)新聞報(bào)道的客觀性和真實(shí)性有更好的理解。對(duì)新聞?dòng)浾叩穆殬I(yè)有更深入的了解,并能體會(huì)其工作的重要性。下面我們來介紹一下第一課時(shí)的授課方式,第一課的教學(xué)目標(biāo)是這樣的第一課時(shí)的教學(xué)目標(biāo)語言目標(biāo):單詞:Occupation, journalist, editor, photographer, curious, personality, enthusiasm

What’s h is hobby ? Is he strong/thin/tall? Where does he/she live? (2)心有靈犀 請(qǐng)兩名學(xué)生(sl和s2)上來,每人拿著紙和筆分別站在教室的兩邊。教師提問:“What does s1’s father do?”站在臺(tái)上的兩名學(xué)生分別把答案寫在各自的紙上。如果兩人的答案完全相同,兩人就算獲勝。教師繼續(xù)問問題“What does …’s…do?”全體學(xué)生一起寫出答案,誰寫的答案正確就可以得一分。 Listen and match (1)教師說:“Do you want to know more about Liu Yun?’’學(xué)生回答后教師說:“Please listen and find out.’’教師放本部分錄音,學(xué)生認(rèn)真聽。
【教學(xué)目標(biāo)】 (1)、區(qū)位的含義;(2)、農(nóng)業(yè)區(qū)位選擇的主要因素;(3)、農(nóng)業(yè)地域的概念、類型?!窘虒W(xué)重、難點(diǎn)及解決辦法] 】重點(diǎn):影響農(nóng)業(yè)的主要自然區(qū)位因素;社會(huì)經(jīng)濟(jì)因素及其發(fā)展變化對(duì)農(nóng)業(yè)區(qū)位的影響。難點(diǎn):運(yùn)用所學(xué)原理,合理評(píng)價(jià)選擇農(nóng)業(yè)區(qū)位。解決方法:知識(shí)講授、案例分析、問題探究與討論【教學(xué)準(zhǔn)備】多媒體課件缺勤登記:三、自然因素的利用和改造1.充分利用:光熱水土并擴(kuò)大范圍2.及時(shí)改造:使之更合理地發(fā)展農(nóng)業(yè)四、社會(huì)經(jīng)濟(jì)因素的發(fā)展變化1.市場(chǎng)區(qū)位及需求的變化2.交通運(yùn)輸條件的改善和冷藏技術(shù)的發(fā)展,擴(kuò)展了市場(chǎng)
(五)平拋運(yùn)動(dòng)規(guī)律的應(yīng)用例1:一架老式飛機(jī)在高出海面45m的高處,以80m/s的速度水平飛行,為了使飛機(jī)上投下的炸彈落在停在海面上的敵船,應(yīng)該在與轟炸目標(biāo)的水平距離為多遠(yuǎn)的地方投彈?不計(jì)空氣阻力。分析:對(duì)于這道題我們可以從以下幾個(gè)方面來考慮:(1)從水平飛行的飛機(jī)上投下的炸彈,做什么運(yùn)動(dòng)?為什么?(2)炸彈的這種運(yùn)動(dòng)可分解為哪兩個(gè)什么樣的分運(yùn)動(dòng)?3)要想使炸彈投到指定的目標(biāo)處,你認(rèn)為炸彈落地前在水平方向通過的距離與投彈時(shí)飛機(jī)離目標(biāo)的水平距離之間有什么關(guān)系?拓展:1、式飛機(jī)在高出海面45m的高處,以80m/s的速度水平飛行,尾追一艘以15m/s逃逸的敵船,為了使飛機(jī)上投下的炸彈正好擊中敵船,應(yīng)該在與轟炸目標(biāo)的水平距離為多遠(yuǎn)的地方投彈?不計(jì)空氣阻力。2、在一次摩托車跨越壕溝的表演中,摩托車從壕溝的一側(cè)以速度v=40m/s沿水平方向向另一側(cè),壕溝兩側(cè)的高度及寬度如圖所示,摩托車可看做質(zhì)點(diǎn),不計(jì)空氣阻力。(1)判斷摩托車能否跨越壕溝?請(qǐng)計(jì)算說明(2)若能跨過,求落地速度?
