高中英語新教材Unit11教案
一、教學分析
1、教材內(nèi)容分析
本單元圍繞“Scientific achievements”這一中心話題，從科學家、科學假說、科學理論、科學探索等方面設(shè)計聽、說、讀、寫等一系列教學活動。“Warming up”部分設(shè)置了三個問題，要求學生就重要的科學成就進行討論，從而幫助學生認識重要的科學成就，了解科學成就對社會發(fā)展、人類進步的重大貢獻，同時激發(fā)學生熱愛科學、投身于科學研究的熱情，探索科學研究的方法。“Listening”部分設(shè)計了兩道材料問題和一道開放性的情景話題。主要培養(yǎng)學生捕捉和篩選信息的能力，然后要求學生在一定語言輸入后進行語言輸出，旨在培養(yǎng)學生的想象能力和應用能力，通過自己的語言體會重大科學成就的意義。“Speaking”部分重點訓練表達意圖和愿望的日常交際用語，以五人小組的活動形式組織學生扮演科學家的角色，陳述各人的研究方向并闡明其重要性來申請科研經(jīng)費。“Reading”部分為一篇介紹中關(guān)村的形成、發(fā)展及其重要意義的記敘文。通過對文章的理解，學習中關(guān)村人的創(chuàng)業(yè)精神。“Language study”部分由詞匯和語法兩部分組成，該部分不僅教授了四種構(gòu)詞法知識，更鼓勵學生通過四項練習，運用構(gòu)詞法知識提高閱讀能力。“Integrating skills”部分設(shè)計了一個閱讀和寫作的練習，在學生了解四大科技成就及其重要性后，要求學生略加擴充寫一篇最偉大的科學成就的文章。“Tips”部分提出了說服性寫作必須論點明確、論據(jù)充分，為寫作提供了寫作方法。
2、教學重點、難點:
本單元的重點在于借助“高科技成就”這一話題，學習、復習涉及這一話題的有關(guān)語言知識和語言技能（見教學目標），激發(fā)學生熱愛科學、奮發(fā)圖強、獻身于科學的熱情。
本單元的難點在于培養(yǎng)學生充分利用已有的英語知識表達自己，談論科學家、科學成就、理想抱負。
二、教學目標
1、語言知識目標
要求學生掌握必要的單詞、詞組和句型：solar, constitution, private, grasp…It’ likely that…, make it possible for sb to do sth…,etc.
掌握一定量的表達“wishes and intentions”的交際功能用語。
同時要求學生掌握本單元出現(xiàn)的構(gòu)詞法及一些常見的前綴后綴及詞根的意義。
2、語言技能目標
通過本單元的內(nèi)容培養(yǎng)學生良好的“聽、說、讀、寫”的技能，使學生能運用所學的知識解決相關(guān)情景中的一些類似問題，并能結(jié)合所給任務，綜合運用新舊知識解決問題，完成任務，在此基礎(chǔ)上鼓勵學生大膽地根據(jù)各自的語言基礎(chǔ)與能力，有個性地解決問題，就科學成就提出獨特的見解。
3、情感目標
1）激發(fā)學生并提高學習英語的興趣， 樂于接受新鮮事物，勇于嘗試：體現(xiàn)課堂教學“主體者”的身份，積極主動地參與教學各環(huán)節(jié)，成為學習的主人：具有個性，培養(yǎng)創(chuàng)造能力。
2）培養(yǎng)同學之間日常融洽相處的感情，樂于合作，善于合作的團體合作精神。
3）通過課文中出現(xiàn)的科學家及科學成就激勵學生熱愛科學、投身科學研究、探索科學研究的方法
三、教學策略
1）開放式教學策略。以有限的課堂為載體，帶學生進入廣闊的知識天地。
2）引趣激趣策略。創(chuàng)設(shè)多種情景（境）激發(fā)學生的興趣，只有讓學生真正有了參與的欲望，才能點燃他們的思維火花。
3)合作學習策略。合作學習強調(diào)通過師生、生生的多邊互動進行人際交往、信息交流，能滿足學生個體內(nèi)部需要。
4)體驗成功策略。使學生在特定的完成任務過程主動積極地獲得和積累相應的學習經(jīng)驗，享受成功的喜悅，從而提高學習興趣和成就動機。
四、學習策略
引導學生利用圖書館和網(wǎng)絡資源進行一系列的自主學習、合作探究的學習策略。對于本單元鼓勵學生課前收集科技成就、中關(guān)村和美國的硅谷的資料，上課時勤思考、主動參與課堂上的各種活動。
五、單元教學設(shè)計
依據(jù)《新課程標準》及對于學生教學目標的要求，課堂設(shè)計本著教學應“以人為本”的總的教學理念，課堂中充分利用網(wǎng)絡資源、設(shè)計相應難度的任務，以增加教學的直觀性和趣味性，提高教學效率。根據(jù)學生學習英語的特點和規(guī)律，學習階段的側(cè)重點，我把本單元劃分六課時完成：聽力、口語、閱讀（2課時）、語言、寫作、評價。

教學反思
本單元的教學設(shè)計從學生實際出發(fā)，以科技成就為主線設(shè)計了若干情景與活動，旨在讓學生積極參與學習活動，開口說英語，并使學生在輕松愉快的氛圍中掌握語言知識，鍛煉閱讀理解能力。在教學實踐中筆者體會到，教學應注意以下幾點：：
1． 學生在合作中學習更有助于提高學生學習的積極性，以及課堂參與的積極性。所以應當發(fā)揮小組功能，在合作中操練。小組活動是課堂活動的主要形式，如何落實小組中各個學生的角色是組織好小組活動的關(guān)鍵。這需要教師長期的訓練。
2．設(shè)計活動時要充分考慮學生的情感態(tài)度，要設(shè)法讓學生在快樂中學習。但教師不能片面地追求所謂的“快樂”，一味強調(diào)課堂氣氛的活躍，而忽視學生對知識的掌握和對學生能力的培養(yǎng)。
3．信息技術(shù)的運用要為教學服務，不可喧賓奪主。在教學過程與信息技術(shù)的整合過程中，教師應注意信息技術(shù)只是一種輔助手段，不能由它控制全部流程。同時也應有效地利用這種手段，加快課堂節(jié)奏，增加課堂容量，提高課堂教學效率，使課堂氣氛更加活躍，讓學生在輕松愉快的環(huán)境中得到感情上的升華。
4．要處理好實踐與反思的關(guān)系。反思是實踐的一面鏡子，能折射出實踐中的成功和不足之處，以期在以后的教學中借鑒成功，改進不足。
