教案點(diǎn)評(píng)：根據(jù)新教材中的以閱讀為主的教學(xué)環(huán)節(jié)所設(shè)計(jì)的一課時(shí)/兩課時(shí)教案。本課閱讀課的目的是讓學(xué)生通過閱讀英語材料，掌握實(shí)驗(yàn)步驟，領(lǐng)悟嚴(yán)謹(jǐn)?shù)目茖W(xué)精神財(cái)富，體驗(yàn)英語語言、問題，學(xué)習(xí)靈活使用語言結(jié)構(gòu)。
這個(gè)教學(xué)過程分三個(gè)步驟：pre-reading,reading,discussion,post-reading,languagepoints
pre-reading：在閱讀課文之前，教師可適當(dāng)?shù)闹v解與本單元有關(guān)的背景知識(shí),運(yùn)用圖片向?qū)W生介紹一些著名的科學(xué)家，通過提問的方式引入課文主題。教師可根據(jù)課文的內(nèi)容和篇章結(jié)構(gòu)，從不同的角度，引導(dǎo)學(xué)生對(duì)課文內(nèi)容進(jìn)行預(yù)測(cè)和討論。
reading：課文分三個(gè)步驟：掠讀（skimming），即帶著某個(gè)問題進(jìn)行搜索式閱讀，這樣能培養(yǎng)學(xué)生捕捉關(guān)鍵句的能力；略讀(skipping)，即教師指導(dǎo)學(xué)生通讀全文，理解課文大意，培養(yǎng)學(xué)生發(fā)現(xiàn)文章或段落的主題句及概括大意的能力；細(xì)讀(extractivereading)，即加深對(duì)課文理解。培養(yǎng)學(xué)生的分析和邏輯推理的能力，并幫助學(xué)生對(duì)文中的難句進(jìn)行句子結(jié)構(gòu)的分析。
discussion:教師開展課堂小組討論，誘發(fā)學(xué)生的參與積極性，培養(yǎng)學(xué)生辯證的看待事物的能力，鍛煉他們說話的條理性和邏輯性。
post-reading：教師通過讓學(xué)生完成課堂練習(xí)，加深學(xué)生對(duì)課文內(nèi)容的理解。
languagepoints:教師點(diǎn)評(píng)課文中的知識(shí)點(diǎn)。
通過以上個(gè)步驟的訓(xùn)練，學(xué)生對(duì)課文理解得比較深刻，同時(shí)也掌握了文中的語言知識(shí)。

Scientistsatwork教案1

俗話說，磨刀不誤砍柴工。教師要準(zhǔn)備好教案，這是教師的任務(wù)之一。教案可以更好的幫助學(xué)生們打好基礎(chǔ)，幫助教師有計(jì)劃有步驟有質(zhì)量的完成教學(xué)任務(wù)。你知道怎么寫具體的教案內(nèi)容嗎？下面是由小編為大家整理的“Scientistsatwork教案1”，僅供參考，大家一起來看看吧。
