1、《戰(zhàn)后資本主義世界經(jīng)濟(jì)體系的形成》是人教版高中歷史必修Ⅱ第八單元第22課,學(xué)時(shí)為1課時(shí)?!稓v史必修Ⅱ》一書用古今貫通、中外關(guān)聯(lián)的八個(gè)專題來著重反映人類社會經(jīng)濟(jì)和社會生活領(lǐng)域發(fā)展進(jìn)程中的重要史實(shí)。從第一單元勾勒“古代中國經(jīng)濟(jì)的基本結(jié)構(gòu)與特點(diǎn)”再到第八單元“世界經(jīng)濟(jì)的全球化趨勢”,以歷史唯物主義觀點(diǎn)清晰闡明經(jīng)濟(jì)全球化是世界生產(chǎn)力發(fā)展的要求和結(jié)果,是不以人的意志為轉(zhuǎn)移的歷史必然趨勢。第八單元的標(biāo)題是《世界經(jīng)濟(jì)的全球化趨勢》,作為最后一單元,從內(nèi)容上講,有強(qiáng)烈的時(shí)代感和現(xiàn)實(shí)意義,是全書內(nèi)容的總結(jié)與升華展望。提起“全球化”這個(gè)十年前才首次出現(xiàn)在美國《商業(yè)周刊》的新名詞,如今卻是地球人都知道了。然而究竟什么是全球化?作為一歷史現(xiàn)象,全球化有其自身內(nèi)部嚴(yán)密完整的體系,其中核心之一便是制度、規(guī)則的全球化,而這正是本課內(nèi)容的著力點(diǎn)。
3.甲午中日戰(zhàn)爭中國戰(zhàn)敗的原因 對于“中國戰(zhàn)敗的原因”這一難點(diǎn)的突破,主要通過設(shè)置問題“中國之?dāng)≡趯?shí)力遜于日本嗎?”通過幻燈片全方位分析其實(shí)中國的綜合國力當(dāng)時(shí)是強(qiáng)于日本的。并且在戰(zhàn)前,日本毫無取勝的把握。讓學(xué)生結(jié)合剛學(xué)習(xí)過的戰(zhàn)爭原因和經(jīng)過進(jìn)行討論,從多方面分析中國戰(zhàn)敗的原因。經(jīng)過討論,學(xué)生可以得出以下結(jié)論:避戰(zhàn)自保方針,沒有積極備戰(zhàn),將領(lǐng)臨陣脫逃,教師肯定并總結(jié)答案進(jìn)行補(bǔ)充。中日對比:中國士兵出身農(nóng)民,軍事訓(xùn)練落后,散兵游勇;日本士兵出身武士,訓(xùn)練有素;中國將領(lǐng)大多臨陣脫逃,并相互猜忌,受當(dāng)時(shí)惡劣的官風(fēng)影響;李鴻章深知北洋海軍實(shí)情,缺乏軍費(fèi),軍備廢弛。為政治資本奉行避戰(zhàn)自保政策,慈禧太后挪用海軍軍費(fèi)過壽,支持李鴻章。使中方處于被動的局面,一再貽誤戰(zhàn)機(jī)。而日本在天皇的帶動下,全民備戰(zhàn),做了充分的戰(zhàn)爭準(zhǔn)備。
生2:每逢清明,或其他一些死者的紀(jì)念日,人們總要為死去的親人燒紙錢。這幅漫畫由燒紙錢演變?yōu)闊凹译姟?,說明隨著社會環(huán)境的變化,人們根深蒂固的一些封建思想,還在影響著人們的生活。要花大力氣去破除封建迷信活動。師:說到底,算命、燒紙錢是封建迷信活動,從文化角度來說,是落后文化。我們一起來看看在現(xiàn)實(shí)生活中,還有哪些落后文化在影響著人們的生活。生1:在一些邊遠(yuǎn)落后地區(qū),大人小孩生了病,不是看醫(yī)生,而是讓巫婆神漢來治,結(jié)果往往耽誤了診療時(shí)間,有的甚至還丟掉了性命。生2:“重男輕女”“多子多?!保t白事大操大辦現(xiàn)象在有些地方還很嚴(yán)重。師:這些落后文化都有哪些共同特征?在你看來,這些現(xiàn)象有哪些危害?生3:這些落后文化,在內(nèi)容上帶有迷信、愚昧、頹廢、庸俗等色彩,在形式上常常以傳統(tǒng)習(xí)俗的形式表現(xiàn)出來,如人們常見的看相、算命、測字、看風(fēng)水等。它會麻痹人的意志,使人消極、悲觀、絕望,對理想、前途、信念喪失信心;破壞社會的風(fēng)氣。
教師點(diǎn)評:根據(jù)小論文的寫作情況對小論文給予肯定,同時(shí)指出其有待修改的地方。學(xué)生在寫小論文的時(shí)候是根據(jù)教材中的提示來寫的,所以對于教材中的這些提示,可以作一個(gè)說明。如“在發(fā)展的過程中,我們面對怎樣的挑戰(zhàn)和困難”,對于這點(diǎn),學(xué)生可能會出現(xiàn)片面看問題的不足,一旦這種情況出現(xiàn),我們就要及時(shí)進(jìn)行說明:我們面臨的挑戰(zhàn)和困難既有來自國內(nèi)的,也有來自國際的,引導(dǎo)學(xué)生學(xué)會用全面的觀點(diǎn)分析問題。教師引導(dǎo)學(xué)生明確作為中學(xué)生可以從以下方面去作準(zhǔn)備:第一,要有國家觀念、民族意識,不斷增強(qiáng)民族自豪感、自尊心和自信心;第二,關(guān)注國家大事;第三,自自覺履行維護(hù)國家統(tǒng)一和民族團(tuán)結(jié)的義務(wù),維護(hù)國家安全、榮譽(yù)和利益;第四,努力學(xué)好科學(xué)文化知識,提高自己的科學(xué)文化素質(zhì)和思想道德素質(zhì),增強(qiáng)各個(gè)方面的能力,掌握振興中華民族的本領(lǐng),這也是中學(xué)生最需要做到的。通過探究活動,培養(yǎng)學(xué)生獲取信息的能力,自主學(xué)習(xí)的能力以及全面看問題的能力,再結(jié)合教師的講授,給學(xué)生一種茅塞頓開的感覺。
科學(xué)是人類認(rèn)識世界的重要工具,閱讀科普說明文不僅可以啟迪心智,了解更多知識。而且更夠激發(fā)學(xué)生對科學(xué)的興趣。學(xué)習(xí)這些文章要注重學(xué)生科學(xué)精神的培養(yǎng),關(guān)注科學(xué)探索的過程,感受科學(xué)家在科學(xué)探索中表現(xiàn)的人格魅力。我們知道一些科學(xué)家就是因?yàn)殚喿x了相關(guān)的科普文章才對某一學(xué)科產(chǎn)生興趣,從而走上成功之路的。我們在講解的時(shí)候可以跟學(xué)生列舉一些例子,讓學(xué)生認(rèn)識到一篇好的科普文章的重大意義。
1.讓學(xué)生拿出長方體摸一摸,問:你有什么感覺?摸的的面是什么形狀?師:誰來摸一摸,老師手上長方體的長方形在哪?(學(xué)生找出長方形)2.讓學(xué)生在自己的學(xué)具(長方體、正方體、圓柱體)上找圖形,并和小組里的同學(xué)說一說。3、指名說,教師把學(xué)生找到的圖形從立體圖形上分離出來,貼于黑板上,師:這些圖形是物體上的一個(gè)面,這就是我們今天要認(rèn)識的圖形。(板書課題——認(rèn)識平面圖形)4.讓學(xué)生說說:從什么物體上找到了什么圖形?5.師:你能想辦法把這些形狀畫到一張紙上嗎?請學(xué)生演示各自不同的方法,然后教師在黑板上沿長方體的一個(gè)面畫出長方形。師:你會畫嗎?請小朋友們用自己喜歡的辦法畫出并剪出長方形、正方形、圓和三角形各2個(gè)。
第一課時(shí):從不同角度觀察一個(gè)物體教學(xué)內(nèi)容:教科書38頁例1、從不同角度觀察一個(gè)物體教學(xué)目標(biāo):1、知識目標(biāo):讓學(xué)生經(jīng)歷觀察的過程,認(rèn)識到從不同的位置觀察物體,所看到的形狀是不同的。能辨認(rèn)從正面、左面、上面觀察到的簡單物體的形狀。2、能力目標(biāo):培養(yǎng)學(xué)生從不同角度觀察,分析事物的能力。培養(yǎng)學(xué)生構(gòu)建簡單的空間想象力。教學(xué)重難點(diǎn):幫助學(xué)生構(gòu)建初步的空間想象力。學(xué)情分析:學(xué)生在日常生活中已經(jīng)積累了豐富的觀察物體的感性經(jīng)驗(yàn),已經(jīng)能辨認(rèn)從不同位置觀察到的簡單物體的形狀,因此可以放手讓學(xué)生自己去探究,讓學(xué)生真正地、實(shí)實(shí)在在地進(jìn)行觀察和操作。教具學(xué)具:長方體、正方體、盒子等。教學(xué)設(shè)計(jì):一、,謎語導(dǎo)入請同學(xué)們猜謎語:“左一片、右一片,摸得著,看不見,是什么呢?”(耳朵)為什么能看見別人的耳朵,卻看不見自己的耳朵呢?因?yàn)槲覀冇^察的角度不一樣,那么今天我們就一起來進(jìn)一步研究觀察物體(板書)
本板塊的活動主題是“談?wù)摴?jié)日活動”(Talk about festival activities),主要是從貼近學(xué)生日常生活的角度來切入“節(jié)日”主題。學(xué)生會聽到發(fā)生在三個(gè)國家不同節(jié)日場景下的簡短對話,對話中的人們正在參與或?qū)⒁H歷不同的慶?;顒?。隨著全球化的進(jìn)程加速,國際交流日益頻繁,無論是國人走出國門還是外國友人訪問中國,都已成為司空見慣的事情。因此,該板塊所選取的三個(gè)典型節(jié)日場景都是屬于跨文化交際語境,不僅每組對話中的人物來自不同的文化背景,對話者的身份和關(guān)系也不盡相同。1. Master the new words related to holiday: the lantern, Carnival, costume, dress(sb)up, march, congratulation, congratulate, riddle, ceremony, samba, make - up, after all. 2.

(一)創(chuàng)設(shè)問題情境:師:小朋友,你們喜歡老師漂亮一點(diǎn)呢還是喜歡老師丑一點(diǎn)?生:大多數(shù)的小朋友說喜歡老師漂亮。師:那你們幫助老師打扮打扮。我最喜歡紅色體恤和這三件下衣,到底怎樣搭配最漂亮呢?請小朋友們給老師出出主意。小朋友們紛紛發(fā)表自己的意見,并說出了自己的理由。師:謝謝。你們的建議都不錯(cuò)。那我這一件上衣、三件下衣能有多少種不同的穿法呢?老師接著問:那我有兩件上衣、三件下衣又有多少種不同的穿法呢?有說4種、有說5種、也有說6種的,到底有幾種呢?(二)1.自主合作探索新知試一試師:請同學(xué)們也試著想一想,如果你覺得直接想象有困難的話可以借助手中的學(xué)具卡片擺一擺。學(xué)生活動教師巡視。2.發(fā)現(xiàn)問題學(xué)生匯報(bào)所寫個(gè)數(shù),教師根據(jù)巡視的情況重點(diǎn)展示幾份,引導(dǎo)學(xué)生發(fā)現(xiàn)問題:有的重復(fù)了,有的漏寫了。
3、開始游戲。學(xué)生總是輸,產(chǎn)生認(rèn)知沖突,從而引起進(jìn)一步探索的欲望。(二)小組內(nèi)游戲,探索結(jié)論。通過小組內(nèi)游戲的方式,進(jìn)行實(shí)驗(yàn),利用統(tǒng)計(jì)的方式呈現(xiàn)實(shí)驗(yàn)的結(jié)果,初步探索教師總能贏的原因。要引導(dǎo)學(xué)生在實(shí)驗(yàn)的結(jié)果中尋找統(tǒng)計(jì)學(xué)上的規(guī)律。(三)理論驗(yàn)證通過組合的理論來驗(yàn)證實(shí)驗(yàn)的結(jié)果??梢杂貌煌姆绞絹磉M(jìn)行組合,讓學(xué)生探討每個(gè)“和”所包含的組合情況的多少與這個(gè)“和”出現(xiàn)的次數(shù)之間的關(guān)系。三、師生共同小結(jié)本次活動1、通過本次活動,你有什么新的收獲?2、師生總結(jié):本次活動通過猜想、實(shí)驗(yàn)、驗(yàn)證等過程,讓同學(xué)們在問題情境中自主探索,解決問題,既發(fā)展了同學(xué)們的動手實(shí)踐能力,又充分調(diào)動了同學(xué)們的學(xué)習(xí)興趣。
【教學(xué)過程】一、從實(shí)際情景入手,引入新知,使學(xué)生學(xué)會在具體情景中用數(shù)對確定位置1.談話引入。今天有這么多老師和我們一起上課,同學(xué)們歡迎嗎?老師們都很想認(rèn)識你們。咱們先來給他們介紹一下我們班的班長,可以嗎?2.合作交流,在已有經(jīng)驗(yàn)的基礎(chǔ)上探究新知。(1)出示要求:以小組為單位,想一想,可以用什么方法表示出班長的位置,把你的方法寫或畫在紙上。匯報(bào):班長的位置在第4組的第三個(gè),他在從右邊數(shù)第二組的第三排…哪個(gè)小組也用語言描述出了班長的位置?請班長起立,他們的描述準(zhǔn)確嗎?剛才同學(xué)們的描述有什么相同和不同?(都表示的是班長的位置,有的同學(xué)說第幾組,第幾行,第幾排……)看來在日常生活中,我們可以用組、排、行、等多種方式,還可以從不同的方位來描述物體的位置。為了我們在確定位置的時(shí)候語言達(dá)成一致,一般規(guī)定:豎排叫列,橫排叫行。
教學(xué)設(shè)計(jì)理念:英語課程標(biāo)準(zhǔn)明確指出,學(xué)生的發(fā)展是英語課程的出發(fā)點(diǎn)和歸宿。小學(xué)英語課的主要目標(biāo)是培養(yǎng)學(xué)生用英語做事情的能力,同時(shí)重視學(xué)科內(nèi)容的有效融合。新課程提倡任務(wù)型教學(xué),讓學(xué)生在教師的指導(dǎo)下通過感知、體驗(yàn)、實(shí)踐、參與和合作等方式完成教學(xué)目標(biāo)。本著這一理念,我在設(shè)計(jì)本課時(shí)從激發(fā)和保持學(xué)生的學(xué)習(xí)興趣入手,精心創(chuàng)設(shè)生活化語言情景,開展豐富多彩的活動,讓學(xué)生在我的指導(dǎo)下進(jìn)行語言交流,感受用英語交流的樂趣和成功感,從而培養(yǎng)學(xué)生用英語進(jìn)行交流的能力。教學(xué)目標(biāo):1. 情感目標(biāo):關(guān)注學(xué)生的內(nèi)在需要,在活動中培養(yǎng)學(xué)生的協(xié)作精神和競爭意識,培養(yǎng)學(xué)生學(xué)習(xí)英語的積極情感態(tài)度。2. 知識目標(biāo):能運(yùn)用所學(xué)語言進(jìn)行交流。3. 能力目標(biāo):通過本課的學(xué)習(xí),學(xué)生能在實(shí)際生活中用英語進(jìn)行問候;培養(yǎng)學(xué)生在課堂上進(jìn)行自主評價(jià)的能力;培養(yǎng)學(xué)生根據(jù)情景猜測語義和在嘗試中自我修正的學(xué)習(xí)策略。
