1、教學(xué)案例設(shè)計及分析一、學(xué)情分析當(dāng)前在中學(xué)生中吸煙現(xiàn)象比較常見， 課本內(nèi)容接近學(xué)生生活， 對學(xué)生有教育意義， 容易激發(fā)學(xué)生的學(xué)習(xí)熱情，易于展開討論。二、教材分析本課是高一必修2 第二模塊里的一篇閱讀課（Reading），出自外語教學(xué)與研究出版社出版的高中英語學(xué)生用書。在第一課Introduction 里面初步接觸和學(xué)習(xí)了描寫抽煙、吸毒及其危害性的詞語， 這一課 Reading 是上文的延續(xù)。 本課 Reading 實際上分為兩篇文章， 第一篇主要講述了一個吸毒者和他的故事；第二篇主要講述了使用可卡因的危害。三、設(shè)計思路本堂課采用任務(wù)型教學(xué)途徑，這種途徑是以應(yīng)用為動力，以應(yīng)用為目的，以應(yīng)用為核心（

2、為用而學(xué)，用中學(xué)，學(xué)了用）的教學(xué)途徑。 任務(wù)型教學(xué)是一種以人為本的，能體現(xiàn)語言價值的，先進的、有效的教學(xué)途徑。學(xué)生帶著任務(wù)學(xué)習(xí)，在完成任務(wù)的過程中逐漸生成的知識，形成的技能。本課將通過任務(wù)型教學(xué)，努力達到課堂活動目的。四、教學(xué)目標(biāo)1.讓學(xué)生學(xué)習(xí)另一些介紹抽煙、吸毒及其危害性的詞語2.通過閱讀包括這些詞匯的兩篇文章并做尋找文章和所屬段落的關(guān)系以及回答問題，判斷正誤等方式，培養(yǎng)聯(lián)想、理解、前后聯(lián)系能力和邏輯分析能力。五、教學(xué)重點和難點1理解有關(guān)吸毒及其危害的知識，找出段落和文章的從屬關(guān)系。2培養(yǎng)閱讀時的聯(lián)想、理解、前后聯(lián)系的能力和邏輯分析能力。3閱讀的同時也培養(yǎng)學(xué)生運用所學(xué)的詞匯進行語言交際的能力

3、。六、教學(xué)輔助手段CAI 課件，錄音機七、教學(xué)過程Step1、 PresentationTeacher uses the pictures connected with drugs to lead in.1.

More than 70% of them are the young people under the age of 35.(教師通過看圖談?wù)?，直觀地將與本課內(nèi)容有關(guān)的圖片展現(xiàn)出來。學(xué)生很自然地被遷移到了新課中來 )Step2、

5、 New WordsAsk students to do an exercise of some new difficult words.Teacher shows the English definitions of new words and then asks them to guess the Chinese meanings of the words.Words: addictive; drug addict; drug dealer; heart rate; increase; inject（教師利用這個練習(xí)讓學(xué)生初步掌握課文里的部分困難單詞，解決閱讀時的語言障礙）Step3、 L

7、能力和邏輯分析能力）Step 4 Surface-reading (silently)Ask students to read parts 1 -6 on page13 and then decide which article they belong to.（教師通過這個練習(xí)培養(yǎng)學(xué)生前后聯(lián)系能力和邏輯分析能力）Step5、 Deep-reading (aloud)I.

10、教師利用這兩個練習(xí)使學(xué)生進一步抓住兩篇文章的細節(jié)內(nèi)容。）Step 6 ConsolidationTeacher asks students to read Article 1 again and then complete the passageAdam, _years old, is a _ addict. When he was_, he started _drugs. He _cannabis from a man. One day, the man _ him some crack cocaine. Later he went to ask theman for _crack coca

13、鼓勵學(xué)生大膽地開口說英語，學(xué)生能用本堂課所學(xué)過的詞匯及知識進行口語表達，這在英語課堂上是很可貴的，盡管學(xué)生的口語表達不是很準(zhǔn)確)Homework: Ask students to write a passage about what you will do if your friend is a drug addict.八、案例分析：1. 利用多媒體制作課件，增大了課堂容量，加大了練習(xí)的力度，也加快了課堂的節(jié)奏。2. 為了調(diào)動學(xué)生的積極性，導(dǎo)入采用了大量的圖片，形象直觀；在做閱讀前加入了一小部分聽力；單詞的處理讓學(xué)生根據(jù)提示猜測詞義。3. 教學(xué)過程體現(xiàn)了素質(zhì)教育的全體性，由淺入深，由易到難，由表及里的閱讀理解練習(xí)能給不同程度的同學(xué)提供體驗成功樂趣的機會，能調(diào)動全體學(xué)生參與的積極性。4. 精選習(xí)題，緊扣課本，難度適中。5. 當(dāng)堂學(xué)習(xí)當(dāng)堂測試。鞏固練習(xí)對學(xué)生進行了本課所學(xué)知識的一個小測試，最后的采訪練習(xí)鍛煉了學(xué)生利用所學(xué)知識進行語言交際的能力。反思這節(jié)課是閱讀課， 我覺得完成了本課的教學(xué)任務(wù)， 實現(xiàn)了教學(xué)目標(biāo)。 在課堂上調(diào)動起了學(xué)生學(xué)習(xí)英語的積極性，全面的訓(xùn)練了學(xué)生的聽、讀、說的能力。讓學(xué)生進行鞏固練習(xí)時，感覺方法有點陳舊，這是今后教學(xué)中要改進的。點評英語閱讀課最重要的是培
