é)案例一．詞匯教學(xué)現(xiàn)狀現(xiàn)行的英語(yǔ)詞匯教育現(xiàn)狀可以總結(jié)如下：1．照本宣科型：一是跟讀單詞，二是講解教材中出現(xiàn)的詞義。2．詞典搬家型：“詞典搬家，全面開花〞至少有三個(gè)弊端：一是消耗時(shí)間，二是沖淡主題，三是擾亂認(rèn)知。3．過(guò)度集中型：3-4周內(nèi)背記整本書的單詞，弊端是單調(diào)苦燥，不符合認(rèn)知規(guī)律。4．敬而遠(yuǎn)之型：老師懂得處理詞匯，但不知如何處理比較合適，即在何時(shí)、怎樣處理課文中的詞匯，一句話，不敢面對(duì)詞匯。二．詞匯教學(xué)目的：1．通過(guò)詞匯教學(xué)，有意識(shí)地培養(yǎng)學(xué)生運(yùn)用詞匯學(xué)習(xí)策略來(lái)識(shí)記詞匯并能在語(yǔ)境下恰當(dāng)?shù)剡\(yùn)用語(yǔ)言的能力。2．通過(guò)使用不同的呈現(xiàn)方法，加深學(xué)生對(duì)詞匯的記憶，促進(jìn)學(xué)生探索詞匯學(xué)習(xí)的最佳方法。3．培養(yǎng)自主學(xué)習(xí)能力三．詞匯教學(xué)過(guò)程本課講的是人教版高中英語(yǔ)第二冊(cè)〔下〕unit18fourgreatinventions的語(yǔ)言點(diǎn)。我提前布置了任務(wù)，要求學(xué)生預(yù)習(xí)并在字典中查找自己認(rèn)為最重要的詞匯包括短語(yǔ)或慣用語(yǔ)。一上課開始例行的值日生詞匯檢查，之后開始上詞匯課。ibegintoshowsomepicturesmadewithpowerpointinacomputer.iaskedthestudentsonebyonetosaywhattheysawinthepictures.inpicture1,thestudentsonlysawasignmeans“stop??thereforesomeofthemcouldn?tmakeconnectionofthisonewithaphrase“beawareof〞.theywouldsaysomesentenceslikethis:〞whenyouwalkacrossthestreet,youmustpayattentiontotrafficlightsorhereisnotallowedtosmokeorothers.atthistimeibegantoaskthestudentswhatthesignsaidandwhenwesawthissign,whatshouldbeawareof.followingthat,allthestudentssaidthattheywouldbeawareofsafety.theniaskedmystudentstomakesentenceswiththephrasebeawareofasmuchaspossible.picture2,3,4,5,6,7areveryeasy.whentheysawthem,theywouldquicklyrememberwhatwordstheywere.onceforawhileiinterestinglyaskedthemwhatmadethesizeofacomputerreducedfromdesktopstolaptopstopalmtopsandiftheypretendedtobespecialistsofacomputerwhethertheyallowfortheircreativity.afterthatthestudentsdiscussedforawhile,thenonereportedtheresult.picture8tendstomakethestudentsremindtheword“experiment〞or〞laboratory〞insteadof“trialbuttheyknewtrialanderrorcouldleadtosuccessandthetruthofsuccessistrialanderror.picture9isabouta“pilot“andpicture10is“heel〞whilepicture11，12and13needhardguess.becauseinthesepicturestheycouldn?tsee“petrol““connection〞and“background〞,teachermustleadin.forexampleiaskedmystudentsthefollowingquestions:whatdoespicture11describe?isitagasstation?whatdoesthedriverdo?whatdoamericanssay“汽油〞？whenyouseepicture12,whatdoyoufeel?whatassociationdoyoumake?(weoftenconnectthischinaknotwithgoodluck)andinpicture13,canyouseetheblackcolor?whatfunctionisitusedas?inthisway,thestudentshadaquickoverviewofsomeimportantnewwordsinunit18.secondly,iquicklyshowthesepicturestothestudents.thenletthemrepeatthesenewwords.inclassifounditinterestingforstudentstolearnnewwordsandwiththismethodstudents?motivationcanbearoused.what?smore,it?seasyforthemtoremembernewwords.whenifinishedthistask,ibegantocheckthestudents?preparations.inlatterhalfclass,thestudentsplayleadingrolesinclass.theyvoluntarilycometotheblackboardtoteachtheothersthekeywordsandphrasesthattheythinkareveryimportantinunit18.althoughitisimpossibleforthemtofindthekeypointsaccurately,inpracticetheyknowhowtolearnnewvocabulary.what?smore,thestudentsareveryactiveininvolvinginclass.四.課后反思反思1：學(xué)生學(xué)習(xí)的主動(dòng)積極性是學(xué)生學(xué)習(xí)的動(dòng)力源泉而學(xué)習(xí)需要是學(xué)生長(zhǎng)期堅(jiān)持的內(nèi)驅(qū)力。學(xué)習(xí)需要是指?jìng)€(gè)體在活動(dòng)中感到有某種欠缺而力求獲得滿足的心理狀態(tài)。它的主觀體驗(yàn)形式是學(xué)習(xí)者餓學(xué)習(xí)愿望和學(xué)習(xí)意想。它包括學(xué)習(xí)的興趣愛(ài)好和學(xué)習(xí)的信念等。所以在教學(xué)中教師應(yīng)想方設(shè)法創(chuàng)造環(huán)境調(diào)動(dòng)學(xué)生的主動(dòng)積極性，挖掘?qū)W生的內(nèi)驅(qū)力。反思2：建構(gòu)主義者認(rèn)為，學(xué)習(xí)是學(xué)習(xí)者主動(dòng)建構(gòu)內(nèi)部心理表征的過(guò)程。這里，“建構(gòu)〞是學(xué)習(xí)者通過(guò)新舊知識(shí)經(jīng)驗(yàn)之間反復(fù)的，雙向的相互作用，來(lái)形成和調(diào)整自己的經(jīng)驗(yàn)結(jié)構(gòu)的過(guò)程。在這種構(gòu)件過(guò)程中，一方面，學(xué)習(xí)者對(duì)當(dāng)前信息的理解需要以原有的知識(shí)經(jīng)驗(yàn)為基礎(chǔ)；另一方面，對(duì)原有知識(shí)經(jīng)驗(yàn)的運(yùn)用又不是簡(jiǎn)單的提取和套用，個(gè)體同需要依據(jù)新經(jīng)驗(yàn)對(duì)原有經(jīng)驗(yàn)本身也做出某種調(diào)整和改造，即同化和順應(yīng)兩方面的統(tǒng)一。學(xué)習(xí)詞匯就是學(xué)生建構(gòu)詞匯的過(guò)程，在詞匯教學(xué)中教師的首要任務(wù)是應(yīng)將新舊知識(shí)建立起某種聯(lián)系，并通過(guò)圖表將知識(shí)形象化的聯(lián)系起來(lái)，以便于學(xué)生長(zhǎng)久地貯存。參考文獻(xiàn)：《教育心理學(xué)》遠(yuǎn)方，20XX2月作者簡(jiǎn)介：__何美俊性別：女出生年月：1969，12學(xué)歷：教育碩士職稱：中教一級(jí)任教科目：英語(yǔ)學(xué)科[篇三：高中英語(yǔ)教師XX詞匯課教案]教學(xué)內(nèi)容：詞義meanings、用法usage、詞匯信息basicinformation、詞匯記憶策略strategies.topicteachingaims:1.knowledgeaim:thestudentswillbeabletoknowthemeaningandusageofthefollowingwords:…2.abilityaim:thestudentswillbeabletousethesewordscorrectlyinwritingandspeaking.3.emotionalaim:thestudentswillbemoreconfident…teachingkeyanddifficultpoints:masterthewords,especially…teachingaid:caiteachingprocedures:1.step1:lead-inshowsomepicturestostudentsandasksomequestions:...2.step2:task-readingthink.readthewordstwice.3.step3:presentationandcomprehension4.step4:practice5.step5:consolidation6.unit6less
