英語(yǔ)教學(xué)案例

1、中學(xué)英語(yǔ)教學(xué)案例分析What things can harm the environment ?What do you think we should do to improve our environment ? ）活動(dòng)目的：通過(guò)列舉污染源，學(xué)生更清楚當(dāng)前環(huán)境的不僅如人意，保護(hù)環(huán)境刻不容緩，從而使學(xué)生增強(qiáng)保護(hù)環(huán)境的意識(shí)。他們動(dòng)腦筋，想辦法，積極討論保護(hù)環(huán)境的措施，在不知不覺(jué)中提高英語(yǔ)語(yǔ)言運(yùn)用能力?；顒?dòng)過(guò)程：T: There is much pollution all over the world now .

12、所設(shè)計(jì)的問(wèn)題實(shí)際上是英語(yǔ)課與生物課中的“環(huán)?！闭鹿?jié)的整合。教師讓學(xué)生列舉污染源，學(xué)生講出了很多的污染源-空氣污染、水污染、土壤污染、噪音污染等等。實(shí)際上讓學(xué)生復(fù)習(xí)了生物課中剛學(xué)的“大氣與健康”、“土壤與健康”、“水與健康”等的環(huán)保知識(shí)。2. 教師讓學(xué)生分組討論如何解決這些污染問(wèn)題，巧妙地運(yùn)用了合作學(xué)習(xí)法，不但培養(yǎng)了學(xué)生探究問(wèn)題和自主解決問(wèn)題的能力，而且也培養(yǎng)了學(xué)生的參政議政的意識(shí)。 同學(xué)們以主人翁的身份，提出了種種解決方法。解決水污染問(wèn)題，他們先用勸說(shuō)的辦法，當(dāng)此法行不通時(shí)，再借助新聞媒體的力量，最后，上告政府；解決空氣污染問(wèn)題，他們號(hào)召人們騎車(chē)上班。當(dāng)老師提醒他們，若家離工作地方很遠(yuǎn)，不能騎

13、車(chē)上班時(shí)，該怎么辦？他們馬上想到了公交車(chē)。他們要求政府增加公交車(chē)輛，建造地鐵。3.老師因勢(shì)利導(dǎo)，請(qǐng)他們回憶一下，以前有否做過(guò)有損于環(huán)保的事情。其實(shí)是英語(yǔ)課與政治課的整合。在這么和諧，民主、激動(dòng)的氣氛中，同學(xué)們毫無(wú)顧忌，暢所欲言，紛紛講述了自己以前的不文明表現(xiàn)。當(dāng)老師問(wèn)他們以后還會(huì)做這種事嗎？他們很真心地回答“No”。自然恰當(dāng)?shù)牡掠凉B透，起到一箭雙雕的作用，使活動(dòng)達(dá)到了高潮?？傊?，整個(gè)過(guò)程，教師不是在“教教材”，而是在“用教材教”。教師根據(jù)學(xué)生的實(shí)際情況和生活經(jīng)驗(yàn)創(chuàng)造性地使用教材，從學(xué)生熟悉的知識(shí)入手，創(chuàng)建一個(gè)個(gè)與學(xué)生生活密切相關(guān)的問(wèn)題情景，讓學(xué)生帶著問(wèn)題思考，尋找解決問(wèn)題的辦法。真正體現(xiàn)了新課

14、標(biāo)的精神-“在發(fā)展語(yǔ)言能力的同時(shí)，發(fā)展思維能力，激發(fā)想象力和創(chuàng)造力?！毙抡n標(biāo)說(shuō)；活動(dòng)不應(yīng)該僅限于課堂教學(xué)，而要延伸到課堂之外的學(xué)習(xí)和生活之中。同學(xué)們回憶自己的不文明行為，作自我批評(píng)，是活動(dòng)的高潮，是自我教育，提高環(huán)保意識(shí)的最有效手段。當(dāng)時(shí)，教師應(yīng)該趁熱打鐵，利用同學(xué)們的這份熱情，讓同學(xué)們利用課余時(shí)間，用英語(yǔ)采訪同年級(jí)的別班同學(xué)，讓同學(xué)們?cè)谕g人面前很自然地回憶自己的不文明行為。然后，以此為依據(jù)，讓本班同學(xué)用英語(yǔ)向全校同學(xué)發(fā)一份以“保護(hù)環(huán)境”為內(nèi)容的倡議書(shū)。這不但會(huì)在全校興起一股學(xué)英語(yǔ)的熱潮，還會(huì)使環(huán)保意識(shí)深入人心。這是實(shí)實(shí)在在的任務(wù)型教學(xué)，體現(xiàn)了學(xué)中用，用中學(xué)的新課標(biāo)精神。讓學(xué)生在實(shí)現(xiàn)任務(wù)的同時(shí)，感受成功，以形成積極的學(xué)習(xí)態(tài)度，促進(jìn)英語(yǔ)語(yǔ)言實(shí)際運(yùn)用能力的提高。這才真正符合新課標(biāo)的理念。思考與探討：1在每一次分組與討論的過(guò)程中，如何更有效的促進(jìn)上、中、下學(xué)生進(jìn)行合作學(xué)習(xí)，互相幫助，使每位同學(xué)在每個(gè)活動(dòng)中都有所得，盡量減少兩極分化，是我們急需要解決而又難以解決的問(wèn)題。2.班額大，在分組討論過(guò)程中，教師很難及時(shí)地對(duì)每個(gè)組進(jìn)行指導(dǎo)。久而久之，必定影響實(shí)際教學(xué)效果。怎么辦？3用“真問(wèn)題”組
