      【教材分析】

      Module 4 Great Scientists?是一篇記敘類文章,類似于人物傳記,介紹我國(guó)科學(xué)家袁隆平的生平、主要貢獻(xiàn)以及他的雜交水稻產(chǎn)生的國(guó)內(nèi)外影響。通過(guò)對(duì)科學(xué)家這一話題的探討,增強(qiáng)學(xué)生對(duì)科學(xué)的興趣,通過(guò)學(xué)習(xí)科學(xué)家的生平及事跡,激發(fā)學(xué)生學(xué)習(xí)動(dòng)機(jī),樹立正確的人生觀、價(jià)值觀,幫助他們樹立遠(yuǎn)大的理想。

      【學(xué)情分析】

      高一的學(xué)生,對(duì)新知識(shí)有濃厚的興趣。

      高一學(xué)生在過(guò)去的學(xué)習(xí)中已經(jīng)有了一定的聽、說(shuō)、讀、寫基礎(chǔ)。

      高一學(xué)生也已經(jīng)具備了一定的自主合作和探究的能力。

      【教學(xué)目標(biāo)】

      1.知識(shí)與技能:學(xué)習(xí)并學(xué)會(huì)運(yùn)用重點(diǎn)單詞、詞組和有用表達(dá)。

      2.過(guò)程與方法:培養(yǎng)學(xué)生的閱讀技能,包括:理解文章主旨、作者意圖;提取、篩選和重組文章中的信息;利用上下文猜測(cè)新詞匯。

      3.情感態(tài)度與價(jià)值觀:使學(xué)生意識(shí)到科學(xué)家也是普通的人,他之所以會(huì)成功,是因?yàn)樗麄兩砩嫌幸恍┛少F的品質(zhì),因此激發(fā)學(xué)生斗志,努力成為對(duì)社會(huì)有用的人。

      【教學(xué)重點(diǎn)】

      提高學(xué)生用英語(yǔ)獲取信息、分析問(wèn)題、解決問(wèn)題的綜合語(yǔ)言運(yùn)用能力

      【教學(xué)難點(diǎn)】

      綜合運(yùn)用詞匯積累、閱讀技巧和閱讀速度完成相關(guān)練習(xí)。

      【教學(xué)策略】

      充分利用多媒體教學(xué)手段,通過(guò)相關(guān)圖片調(diào)動(dòng)學(xué)生學(xué)習(xí)興趣

      在語(yǔ)篇閱讀中,采用“整體把握文章大意—分段細(xì)讀獲得細(xì)節(jié)信息—通讀全文深層次理解”的方法和策略。

      【學(xué)習(xí)策略】

      自主學(xué)習(xí),小組探究,合作學(xué)習(xí)。

      【教具準(zhǔn)備】

      多媒體計(jì)算機(jī)教學(xué),黑板,學(xué)案。

      【教學(xué)步驟】

      Step 1. Lead-in

      結(jié)合圖片,將文章中一些難掌握的詞匯呈現(xiàn)給學(xué)生,幫學(xué)生掃除一些閱讀中的障礙。

      agriculture,staple,cross,hybrid,yield,sterile,species,breeding ,genetics

      (設(shè)計(jì)意圖:用圖片的方式導(dǎo)入,可以避免學(xué)生在學(xué)習(xí)詞匯的過(guò)程中感到枯燥,可以激發(fā)學(xué)生學(xué)習(xí)的興趣。另外,通過(guò)圖片,可以讓學(xué)生很直觀地感知單詞意思,印象深刻,不易忘記。)

      Step 2. Pre-reading

      Read the title of the passage and answer the following questions.

      1.The title of this passage is The Student Who Asked Questions. In your opinion, will it be about something or about someone?

      2.When a passage is about someone, usually what does the writer write about him/her?

      【設(shè)計(jì)意圖】使學(xué)生明白文章的標(biāo)題對(duì)于文章的概括性

      Step 3. Fast-reading

      Para 5:e.Yuan Longping is a leading figure in the rice-growing world.

      Para 6:f.As a boy, he was called“the student who asked questions”。

      (設(shè)計(jì)意圖:讓學(xué)生通過(guò)這一活動(dòng)初步了解每一段的內(nèi)容,對(duì)文章有個(gè)大概感知。)

      1. What are the advantages of hybrid rice?

      2. What is the most important crop in Pakistan?

      3. Whats the feature of the new hybrid rice?

      (設(shè)計(jì)意圖:通過(guò)設(shè)置一些問(wèn)題讓學(xué)生回答,不僅讓學(xué)生積極參與到思考當(dāng)中,一步步深入了解了文章的細(xì)節(jié)內(nèi)容,而且提高了學(xué)生的閱讀能力。)

      【板書設(shè)計(jì)】

      Module 4 Great Scientists

      The Student Who Asked Questions

      評(píng)價(jià)與反思:

      1.整節(jié)課以學(xué)生活動(dòng)為主,教師適當(dāng)引導(dǎo),體現(xiàn)了以學(xué)生為主體的教學(xué)理念。

      2.本節(jié)課通過(guò)不同的閱讀活動(dòng),訓(xùn)練學(xué)生理解文章主旨,獲取細(xì)節(jié)信息的能力,達(dá)到了與高考接軌的目的。

      3.用激勵(lì)性語(yǔ)言評(píng)價(jià)各小組在課堂中的活動(dòng),激發(fā)了學(xué)生學(xué)習(xí)興趣,學(xué)生獲得了成就感,增強(qiáng)了自信心。

      整體感覺不錯(cuò),但在任務(wù)設(shè)置上有些缺乏層次,對(duì)后進(jìn)生來(lái)說(shuō)難度稍大,容易挫傷其積極性,這點(diǎn)需要在以后的備課中改進(jìn)。
