2019-2020年高一英語 Unit 16《Scientists at work》Reading說課稿 新人教版 課題名稱 Unit16 Scientists at work（閱讀課） 教材版本 現(xiàn)行人教版高中英語 授課時間 40分鐘 各位老師： 大家好！ 我說的課題是高中一年級英語下冊第16單元Scientists at work的第三課時Reading。 本單元的設(shè)計與實(shí)施是建立在學(xué)生經(jīng)過高一上半學(xué)期新教材學(xué)習(xí)基礎(chǔ)之上。學(xué)生已經(jīng)逐步的適應(yīng)了在活動與任務(wù)中學(xué)習(xí)英語以及如何處理語言知識與活動開展的關(guān)系。并且，他們也已經(jīng)形成并培養(yǎng)了一定的小組合作學(xué)習(xí)及自主學(xué)習(xí)的能力。 我說課的內(nèi)容包括三部分，一是教材分析，二是教法學(xué)法分析，三是說教學(xué)程序。 一、 教材分析 1、 單元背景分析 隨著科學(xué)技術(shù)的發(fā)展，各種各樣新的發(fā)明和發(fā)現(xiàn)都層出不窮。生活在這樣一個知識爆炸的年代，學(xué)生們更應(yīng)用心去體會并感受科技和發(fā)明創(chuàng)造者給生活帶來的變化，進(jìn)而能聯(lián)想到他們平時所學(xué)的學(xué)科及知識，并用英語為媒介進(jìn)行知識的整合與串聯(lián)。同時從另一個角度來說，科技進(jìn)步的同時，我們的社會也產(chǎn)生了各種各樣的矛盾與爭論，因此如何正確的看待或處理這些問題，也成為廣大學(xué)生應(yīng)該了解并掌握的知識。通過學(xué)習(xí)偉人的事跡，走近科學(xué)家的精神世界，學(xué)習(xí)科學(xué)家為尋求真理的獻(xiàn)身精神，求是精神，樹立向上的學(xué)習(xí)和生活態(tài)度，培養(yǎng)學(xué)生高尚的情操。 2、教材內(nèi)容分析 w 本課是高中一年級英語下冊，unit 16 Scientists at work 中的Reading. 本單元的中心話題是science and scientists。話題依附于聽力、對話、閱讀與寫作等語言載體中。本單元的話題內(nèi)容與學(xué)生的日常學(xué)習(xí)有著密切的關(guān)系，應(yīng)該說是以英語為媒體讓學(xué)生表達(dá)他們對平時理化生等理科課程，特別是相關(guān)實(shí)驗(yàn)，所想到及感受到的內(nèi)容。因此，盡管本單元的話題對學(xué)生而言有著一定的難度，但卻有體現(xiàn)出了以學(xué)生為中心，貼近學(xué)生生活而又富有時代氣息的特點(diǎn)。 Reading講述的是科學(xué)家Franklin著名的風(fēng)箏實(shí)驗(yàn)，從而證明Lighting and electricity are the same的故事。學(xué)生在理解文章的基礎(chǔ)上，能充分感受到實(shí)驗(yàn)對于科學(xué)工作的重要性及科學(xué)家是如何獲得事業(yè)上的成功的，并了解作為一個科學(xué)家應(yīng)具備的品質(zhì)。同時能落實(shí)材料中所出現(xiàn)的一些單詞與短語的使用。 w 本課時主要分為三部分: 1）Pre-reading. (讀前準(zhǔn)備) “ 讀前”部分是Reading的前奏，要求學(xué)生填出所學(xué)理科課程領(lǐng)域18世紀(jì)和19世紀(jì)的重要發(fā)現(xiàn)并闡釋其之所以重要的理由。同時，還提醒學(xué)生回憶自己曾做過的一次科學(xué)實(shí)驗(yàn)及其感受，以便于學(xué)習(xí)閱讀部分的福蘭克林的實(shí)驗(yàn)。 2）.Reading (閱讀) “閱讀”部分詳細(xì)描述了富蘭克林所進(jìn)行的一次科學(xué)實(shí)驗(yàn)：在電閃雷鳴時放飛風(fēng)箏以驗(yàn)證閃電和電的關(guān)系。文中詳細(xì)記述了富蘭克林實(shí)驗(yàn)的目的、材料、過程、注意事項(xiàng)和所得結(jié)論。通過該篇文章的學(xué)習(xí)，學(xué)生要學(xué)會如何描述實(shí)驗(yàn)過程（這一點(diǎn)非常實(shí)用），并學(xué)習(xí)富蘭克林對科學(xué)的執(zhí)著、探究精神。 3）Post-reading（讀后） “讀后”部分共設(shè)計了三種類型料到練習(xí)：練習(xí)1：通過挑選正確論述檢查學(xué)生對課文的細(xì)節(jié)理解。練習(xí)2：是三個問題，涉及此次實(shí)驗(yàn)的一些科學(xué)常識。練習(xí)3：以圖片形式檢查學(xué)生對課文中提到的實(shí)驗(yàn)條件及方法的理解，圖片2展示實(shí)驗(yàn)情景，圖片4展示風(fēng)箏制作過程。圖片1和3 不正確。 三部分旨在培養(yǎng)和提高學(xué)生的閱讀能力，所以特將此三部分科學(xué)地整合成一節(jié)閱課。 3、教學(xué)重點(diǎn) 1）、能繼續(xù)運(yùn)用各種閱讀微技能進(jìn)行有效的閱讀， 同時能在閱讀中繼續(xù)培養(yǎng)猜測單詞詞義的能力。同時掌握文中出現(xiàn)的單詞與短語的使用。 2）、能進(jìn)一步了解一詞多義及合成詞的知識。以便能更好的區(qū)別單詞詞義與猜測單詞詞義，利用構(gòu)詞法知識擴(kuò)充詞匯量，并能真正做到為閱讀服務(wù)。 4、教學(xué)難點(diǎn) 1）、能就課文內(nèi)容完成一些開放性的話題討論，能把課文的內(nèi)容得以延伸與拓展。 2）、掌握并運(yùn)用一些key words and expressions, such as make /do an experiment on…, fort, conduct, charge, a great of, prove, tear, sharp, explain, pick out, test on, doubt, conclusion and so on. 3)、指導(dǎo)學(xué)生通過各種渠道如圖書館、網(wǎng)絡(luò)等資源查找資料。 5、教學(xué)目標(biāo) 根據(jù)課文特點(diǎn)及新課標(biāo)對高一年級學(xué)生英語學(xué)習(xí)能力的要求，本課的教學(xué)目標(biāo)我定為以下兩個方面：一、語言目標(biāo)，二、情感目標(biāo)和文化意識。 1） 語言目標(biāo) ①語言知識 詞匯：學(xué)習(xí)并使用一些與science 和scientists有關(guān)的詞匯。 語法：進(jìn)一步了解一詞多義現(xiàn)象與合成詞的構(gòu)成。 功能：學(xué)習(xí)如何就某一事物給予別人指導(dǎo)與說明。 話題：掌握有關(guān)實(shí)驗(yàn)說明的話題表達(dá)以及如何從正反兩方面對某一話題進(jìn)行分析討論。 ②語言技能 強(qiáng)化略讀、查讀等閱讀微技能，訓(xùn)練通過尋找關(guān)鍵詞，主題句等方式更快速并準(zhǔn)確的確定文章的段落大意，理清文章的總體框架與脈絡(luò)。繼續(xù)運(yùn)用已經(jīng)掌握的基本猜詞技巧猜測部分單詞，并在上下文體驗(yàn)中感受某些佳句給讀者帶來的深層含義。 2） 情感態(tài)度與文化意識 （1）進(jìn)一步培養(yǎng)小組合作學(xué)習(xí)的能力，通過調(diào)查、采訪、討論等活動完成任務(wù)，取長補(bǔ)短，加強(qiáng)團(tuán)體協(xié)作意識。 （2）引導(dǎo)學(xué)生用英語進(jìn)行不同學(xué)科特點(diǎn)的思考，體會學(xué)科之間的聯(lián)系與區(qū)別。通過話題啟發(fā)學(xué)生積極思考，調(diào)動學(xué)生的學(xué)習(xí)興趣。 （3）指導(dǎo)學(xué)生用批判的思維去接受新的事物，增強(qiáng)他們的辯論意識與能力。 （4）意識到科技工作的艱苦以及所必需的個人品質(zhì)與素質(zhì)，鼓勵學(xué)生在學(xué)習(xí)過程中的創(chuàng)新精神與實(shí)踐能力。 二、教法學(xué)法分析 （1）以任務(wù)型教學(xué) (Task-based Language Teaching)作為課堂教學(xué)設(shè)計之理念，具體采用情景教學(xué)法（Situational Approach），交際教學(xué)法（municative Approach），整體語言教學(xué)法（Whole Language Teaching）等教學(xué)方法。 （2）在教學(xué)中突出交際性，注重讀寫的實(shí)用性；同時適時進(jìn)行情感與策略調(diào)整，以形成積極的學(xué)習(xí)態(tài)度，促進(jìn)語言綜合運(yùn)用能力的提高。 （3）堅(jiān)持“教師為主導(dǎo)，學(xué)生為主體，任務(wù)為基礎(chǔ)”的教學(xué)原則，在課堂教學(xué)的不同環(huán)節(jié)教師應(yīng)扮演自身作為“設(shè)計者，研究者，組織者，促進(jìn)者，協(xié)調(diào)者”的角色。 （4）貫徹“教中學(xué)，學(xué)中用”策略，真正使學(xué)生學(xué)以致用。 為了能很好地突出重點(diǎn)，突破難點(diǎn)，圓滿完成教學(xué)任務(wù)，取得良好的教學(xué)效果，我抓住重點(diǎn)，聯(lián)系實(shí)際，以學(xué)生為主體，教師為主導(dǎo)，讓學(xué)生集中練習(xí)。為了激發(fā)學(xué)生的興趣愉快地學(xué)，我采用競猜游戲、快速閱讀（查讀）得出課文段落大意、討論和媒體實(shí)例演示等教學(xué)環(huán)節(jié)，讓學(xué)生充分體現(xiàn)課堂教學(xué)“主體者”的身份。 指導(dǎo)學(xué)生運(yùn)用已學(xué)會的抓重點(diǎn)、做記號、摘筆記等方式對所學(xué)內(nèi)容進(jìn)行整理與歸納，并鼓勵學(xué)生增加與教師和同學(xué)交流、合作，繼續(xù)培養(yǎng)正確的自我評價與相互評價的習(xí)慣，從而總結(jié)交流學(xué)習(xí)所得，進(jìn)一步形成有效的學(xué)習(xí)方法。并指導(dǎo)學(xué)生把英語學(xué)習(xí)從課堂延伸到課外，發(fā)揮已掌握的使用工具書，查找資料、上網(wǎng)等方式增加用英語思維與表達(dá)的能力，了解實(shí)驗(yàn)對于科學(xué)研究的重要性，樹立正確的向上的學(xué)習(xí)態(tài)度，形成具有批判性的看問題習(xí)慣。 三、說教學(xué)程序 Step 1.Revision 1).

Franklin’s Famous Kite Experiment Step 6.Post ---reading 1. Finish Ex.2 in post ---reading (P 25) (Show the Qs on the screen) T: Please look at the screen and discuss the following questions in groups: (1)What do you think of Benjamin Franklin? (2)What can you learn from the experiment and also Franklin? 2. Describe Franklin’s experiment. T: It’s your turn to describe Franklin’s experiment in your own words. (In order to show that lightning and electricity are the same, Franklin built a strong kite. When the bad weather came, he did his experiment by using his kite and condenser. He found that the string was getting charged and he could feel a light but very clear electric shock. So he stored much electricity in the condenser. This experiment proved his idea. To do this experiment, four objects are needed: a kite, a key, some bad weather and a condenser. Then the next three steps are very important. First, fix a very sharp piece of metal. Second, fasten a key to the end of the long string. Third, tie a silk ribbon to the string.) Step 7.Consolidition Fill in the following forms according to the text. (Show the form on the screen) Show the suggested answer on the screen: Aim Things needed Functions Instructions Description Result To show that lighting and electric are the same. a silk kite to last longer in bad weather Paragraph 5 & 6 Paragraph 3 1.The electricity can be collected and stored in the condenser; 2.can be used to do other experiments; 3.proves that lightning and electricity are the same. a key to direct electricity towards the condenser bad weather to have lightning a condenser to collect and store electricity a shed to keep himself and his tools dry so that he himself would not be hit by the lightning a silk ribbon to protect you from the electricity Wooden sticks To build the frame of the kite by making a small cross a string to control the kite by tying a long string to the cross a sharp piece of metal to attract electricity Step 8 Summary Today we’ve read a science report.
