Module 4 Great Scientists?是一篇記敘類文章,類似于人物傳記,介紹我國科學(xué)家袁隆平的生平、主要貢獻以及他的雜交水稻產(chǎn)生的國內(nèi)外影響。通過對科學(xué)家這一話題的探討,增強學(xué)生對科學(xué)的興趣,通過學(xué)習(xí)科學(xué)家的生平及事跡,激發(fā)學(xué)生學(xué)習(xí)動機,樹立正確的人生觀、價值觀,幫助他們樹立遠大的理想。
【學(xué)情分析】
高一的學(xué)生,對新知識有濃厚的興趣。
高一學(xué)生在過去的學(xué)習(xí)中已經(jīng)有了一定的聽、說、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】

2.過程與方法: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;利用上下文猜測新詞匯。
3.情感態(tài)度與價值觀:使學(xué)生意識到科學(xué)家也是普通的人,他之所以會成功,是因為他們身上有一些可貴的品質(zhì),因此激發(fā)學(xué)生斗志,努力成為對社會有用的人。
【教學(xué)重點】
