任務(wù)驅(qū)動(dòng)教學(xué)法是一種以建構(gòu)主義教學(xué)理論為基礎(chǔ)的教學(xué)方法,是以學(xué)生為學(xué)習(xí)主體,以教師為引導(dǎo)者,以情境為教學(xué)支撐,以任務(wù)和問題作為教學(xué)動(dòng)力,注重知識(shí)技能、遷移能力的提升,促進(jìn)學(xué)生全面發(fā)展的一種新型教學(xué)方式。牛津譯林版英語教材八(上)Unit7 閱讀版塊Seasons of the year的主題為人與自然,體裁為詩歌,內(nèi)容上呈現(xiàn)了冬、春、夏、秋四季景物的變化。詩歌雖短但富有韻律美、語言美和意象美。筆者將任務(wù)驅(qū)動(dòng)法運(yùn)用到閱讀版塊Seasons of the year的教學(xué)中,用明確的任務(wù)引導(dǎo)學(xué)生學(xué)習(xí)詩歌,通過任務(wù)的層層推進(jìn),讓學(xué)生真正走近詩歌,感受詩歌之美,成為詩歌的創(chuàng)作者。
到本節(jié)課結(jié)束時(shí),學(xué)生能夠:
1.熟悉詩歌中描述四季的詞和短語;
2.掌握簡單的詩歌朗讀技巧;
3.識(shí)別詩中的韻律,運(yùn)用韻律完成詩歌選段的半開放創(chuàng)作,以及初步創(chuàng)作出有韻律的詩歌;
4.識(shí)別出詩中的擬人修辭手法并初步了解另外兩種修辭手法(重復(fù)和明喻)。
筆者挑選了能顯示季節(jié)特色的四張圖片,讓學(xué)生從天氣、活動(dòng)、衣著、食物等角度推測圖片所屬季節(jié),在引入話題的同時(shí)也處理了部分生詞,在情境中激發(fā)了學(xué)生的學(xué)習(xí)興趣。
T:Which season is it in the first picture?
S:Winter.
T:Why?
S:There is snow.
T: Great.What else can you tell? Are they wearing T-shirt?
S:No.They are wearing warm clothes.
T: Wonderful.They are wearing warm clothes because the temperature drops(生詞).So we can know the season from the weather(板書).
隨后,筆者呈現(xiàn)古詩《春曉》的中英文版本,設(shè)置任務(wù)引導(dǎo)學(xué)生關(guān)注韻腳,復(fù)習(xí)韻律的概念。
T: What is special about two poems? Pay attention to the words in red.
Ss:Ya yun(押韻).
T: Excellent! You found rhymes.So we can say lying rhymes with...?
Ss:Lying rhymes with crying.
T:What other rhymes can you find?
Ss:Showers rhymes with flower.
T:What about the Chinese poem?
Ss:曉rhymes with鳥.
T: Good job! So we can say words rhyme if the last syllables make the same or similar sound.
首次執(zhí)教時(shí),筆者通過問題鏈的方式引導(dǎo)學(xué)生關(guān)注詩節(jié)的韻律和修辭手法。朗讀時(shí),教師領(lǐng)讀,學(xué)生模仿。第二次執(zhí)教時(shí),除了常規(guī)的問題鏈,筆者還增設(shè)了多樣的任務(wù)。比如,筆者讓學(xué)生根據(jù)文本選擇適合的背景音樂,提高學(xué)生的參與度;在朗讀環(huán)節(jié),筆者邀請(qǐng)學(xué)生朗讀并請(qǐng)學(xué)生點(diǎn)評(píng);在賞析詩歌時(shí),筆者引導(dǎo)學(xué)生自己逐步總結(jié)出朗讀技巧(read slowly,loudly,clearly,emotionally)。
T:Can you find rhymes here?
S:Days rhymes with shade.
S:Pool rhymes with cool.
T: Wonderful.Would you please try to read the part slowly and loudly?
(Students read together.)
T: You did a good job.After reading it,which music do you think fits the poem better?
Ss:The second.
T:Why?What did you hear?
S1:The quiet stream.
T: How did you feel about this part?What’s summer like in poet’s eyes?(Can you find some adjectives?)
Ss:Sweet.Lazy.Cool.
T: Pay attention to the word lazy.When will you use the word?
S:I am lazy.
T:Well done.We normally use the adjective to describe a person.When we use it to describe things or animals, we also call it personification.Now close your eyes and feel the season first.This time, try to read emotionally and add your feelings.
首次執(zhí)教時(shí),筆者選取了五段詩歌選節(jié)挖空,鼓勵(lì)學(xué)生通過韻律判斷空格內(nèi)需要填寫的詞匯。這樣的方式雖然看起來輸入量很大,但是角度單一,只涵蓋一種修辭手法。另外,詩歌選節(jié)無關(guān)信息較多,涉及的生詞影響了學(xué)生閱讀。第二次執(zhí)教時(shí),筆者選取了四段詩歌選節(jié)并進(jìn)行適當(dāng)精簡,選節(jié)涵蓋課內(nèi)的擬人修辭手法和新增的比喻、重復(fù)修辭手法。雖是新增內(nèi)容,但任務(wù)難度符合學(xué)情,學(xué)生很快就能完成任務(wù)。
The lonely tree said to himself,“______”
Woke up to find himself wearing white.
T:Which word should we fill in?Why?
S:Night.
S: Good night! Because it rhymes with white.And the tree woke up next day.
T:Wonderful.Any figure of speech?
S:Personification.
T:How do you know that?
S:The tree is lonely.
T:Great.Any other word to show personification?
S: Woke up.That is what I do every morning.
S:Wearing white.
在學(xué)生正式創(chuàng)作詩歌之前,筆者還通過圖片激活學(xué)生腦內(nèi)的四季印象,在導(dǎo)學(xué)案中增補(bǔ)韻腳相同的常見詞匯,通過提問引導(dǎo)學(xué)生運(yùn)用導(dǎo)學(xué)案中的詞匯進(jìn)行簡單的詩句創(chuàng)作,為接下來的詩歌創(chuàng)作做好鋪墊。
T: What can we do during the summer?Walk by...?
S:Walk by the stream and eat ice cream.
T:Sit on the beach and have a...?(肢體語言表明睡覺)
S:Have a nice dream!
T: Awesome! We have already created a short poem together!
寫作的完成并不意味著教學(xué)任務(wù)的結(jié)束。首次執(zhí)教時(shí),筆者在詩歌的展示和評(píng)價(jià)環(huán)節(jié)以教師的評(píng)價(jià)為主,且缺少對(duì)主題意義的思考和串聯(lián)。第二次執(zhí)教時(shí),筆者將評(píng)價(jià)前置,讓學(xué)生有據(jù)可循,并且在評(píng)價(jià)部分采用生生互評(píng)、師生共評(píng)的方式。
Checklist
1.Choose one season to write at least 2 lines.
2.Your poem should at least have one rhyme(押韻).
3.Try to use one figure of speech(修辭手法).
學(xué)生作品1

T: Well done.Now you know how to use the checklist.Anyone wants to try to assess others’poems?
英文詩歌要讀什么?如何讓學(xué)生主動(dòng)學(xué)習(xí)詩歌甚至創(chuàng)作詩歌?這些都是執(zhí)教者在教學(xué)前需要思考的問題。傳統(tǒng)的英文詩歌教學(xué)的重點(diǎn)在詞匯、句型和韻律的學(xué)習(xí)上,而忽略了詩歌的意象美和語言美,學(xué)生較難產(chǎn)生可遷移的結(jié)構(gòu)化知識(shí)。
任務(wù)驅(qū)動(dòng)教學(xué)法是以任務(wù)為明線,以培養(yǎng)學(xué)生的知識(shí)與技能為暗線的教學(xué)方法。運(yùn)用任務(wù)驅(qū)動(dòng)法的課堂可以形成更合理的課堂結(jié)構(gòu),讓學(xué)生有更充足的時(shí)間開展自主學(xué)習(xí),從而實(shí)現(xiàn)教與學(xué)的有效配合。
經(jīng)過具體的教學(xué)實(shí)踐后,筆者發(fā)現(xiàn)任務(wù)設(shè)置、任務(wù)實(shí)施、激勵(lì)評(píng)價(jià)等方面存在問題。初次執(zhí)教時(shí),筆者急于求成。在教學(xué)目標(biāo)模糊的情況下,設(shè)置任務(wù)的難度和梯度出現(xiàn)偏差,導(dǎo)致教學(xué)任務(wù)斷層。同時(shí),因?qū)W生主體地位的缺失,產(chǎn)出部分不盡如人意。因此,筆者圍繞文本材料和課堂生成效果進(jìn)行分析和研討,從以下幾個(gè)方面進(jìn)行了改進(jìn):細(xì)化教學(xué)目標(biāo),遞進(jìn)教學(xué)任務(wù);強(qiáng)化學(xué)生主體,多元激勵(lì)評(píng)價(jià);提煉詩歌主題,提供有效輸入。最終,課堂的互動(dòng)和產(chǎn)出環(huán)節(jié)都呈現(xiàn)出良好的效果。
當(dāng)然,任務(wù)驅(qū)動(dòng)法在實(shí)際運(yùn)用中仍存在一些不足。由于詩歌的可探討性極強(qiáng),教師很難面面俱到。任務(wù)設(shè)計(jì)流程和流程設(shè)置也容易出現(xiàn)偏差。另外,學(xué)生的層次水平不一,如何設(shè)計(jì)出貼合各個(gè)層次學(xué)生水平的任務(wù)也是一個(gè)難題,如何實(shí)現(xiàn)課堂聚焦也是教師需要關(guān)注的問題。
總之,雖然還有需要繼續(xù)探索、改進(jìn)的地方,但運(yùn)用任務(wù)驅(qū)動(dòng)法的初中英語詩歌教學(xué)可以有效激發(fā)學(xué)生對(duì)詩歌學(xué)習(xí)的興趣,發(fā)揮學(xué)生主體地位,讓學(xué)生在任務(wù)遞進(jìn)中感受詩歌美,感悟四季美,感恩生活美。
