Step 4 Reading ----- Theme Parks –---- Fun and More Than Fun1.Predict : Read the title and the pictures on P. 34 and PredictWhat is the meaning of the title “Theme Park – Fun and more than fun”?(The title means that theme parks are fun to visit, but that they can also be educational and can offer useful information.)2.Skimming Fast read and answer:What activities can we take in a theme park?Amusement park: Bumper car Merry-go-round slide bungee jumping Free-fall rides Horror films Pirate ship Ferris wheel roller coaster3.Scanning Read again and you will find various theme parks are mentioned in the passage . Then what are they ?Theme parks: Sports theme park History theme park Culture theme park Marine or Ocean theme Park Future park Science theme park Disneyland4.Careful reading and find the main idea of each paragraph:THEME PARKS---- entertaining/ educationalPara.1 Traditional parks are places to go for relaxation and to have time away from our busy lives.Para.2 Theme parks are different They’re large and full of things to do, see and buy.Para.3 Theme parks are built around a single idea or theme. One example is a sports park.Para.4 Another kind of theme park is historical more and cultural and can be educational.Para.5 Disneylandwas the first theme park. It is based on the fantasy life and characters of Disney’s films.Para.6 Some examples of educational theme parks include sea world parks and science parks.

Language learning needs a context, which can help the learners to understand the language and then can product comprehensible output, so computer has the advantages to make the materials attractive.Part 3 Learning MethodsTask-based, self-dependent and cooperative learningPart 4 Teaching ProcedureStep One Lead-in“Interest is the best teacher.” Therefore, at the very beginning of the class, I should spark the students’ mind to focus on the centre topic “the band”. I’ll show some pictures of food to attract their attention and then bring some questions.Question:What kind of food they like?What should go into a good meal?The answers must relate to the diet. After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively. In addition, the task is to develop the students’ reading skill by making prediction and to encourage the students to express their thoughts in English and cooperate with each other.Task 2 Main idea of each paragraphCooperative learning can raise the students’ interest and create an atmosphere of achievement. Based on this theory, I divide the whole class into 4 groups to skim the whole text and get the main idea of each paragraph.

Knowledge objectives:(1) to make Ss grasp the usage of words, expressions and sentence structures: statistics, struggle, thanks to, rid of, some patterns for persuasion, the “ing” form as subject and object;(2)to use learnt knowledge to persuade sb.Ability objectives:(1) to develop Ss’ reading skills(skimming, scanning, word guessing);(2) to improve Ss’ speaking, communicating and cooperating skills.Emotional objectives:to make Ss know the contribution of Yuan,and learn his spirit and his simple life time.Teaching important and difficult points:(1) some words, expressions and sentence structures mentioned above;(2)the content of the text;(3)training their reading and speaking skills.Teaching methods: CLT, TBLT,QT.Learning strategies: CLS, QLS, TBLS.Teaching procedures:Step 1 lead-in: (1) teacher plays a piece of recent news from CCTV about the harvest of the super hybrid rice, and ask students whether they know Yuan or not, and talk about him and his contribution.(2)Brain storm: let Ss describe Yuan in their minds including his appearance, his living condition and so on.Step 2 fast reading tasks:(1)teacher introduces Yuan and super hybrid rice(2)make Ss read the text as fast as possible with questions. Such as: what’s the general ideaof this passage? What’s Yuan’ dream? (skimming and scanning skill)Step 3 intensive reading tasks(1)let Ss read the text silently, find topic sentence of each paragraph and draw the difficult sentences and the knowledge what they don’t understand.(words guessing)(2)teacher and Ss talk about the important words, expressions and sentences together, and ask Ss to retell the content of the text.(summarizing and paraphrasing)(3)teacher summarize this part.(4) read again following the courseware.

在接下來的細(xì)讀環(huán)節(jié),我套用了高考對(duì)閱讀理解的考查方式設(shè)置了5個(gè)問題,分別為三個(gè)推理判斷題,一個(gè)細(xì)節(jié)題和一個(gè)主旨大意題。學(xué)生需要對(duì)文章的內(nèi)容進(jìn)行分析、歸納、推理、猜測等高級(jí)思維活動(dòng)才能做出正確的回答?!驹O(shè)計(jì)意圖】這一過程是對(duì)學(xué)生進(jìn)行細(xì)讀的訓(xùn)練,培養(yǎng)學(xué)生獲取特定信息和挖掘文章深層次信息的能力。第三環(huán)節(jié):Intensive-reading (精讀) 15′第三個(gè)環(huán)節(jié)精讀,既是最重要的環(huán)節(jié),也是突破本課重難點(diǎn)的關(guān)鍵。首先,讓學(xué)生思考劇本中人物看到百萬英鎊前后的態(tài)度發(fā)生了怎樣的變化。其次,讓學(xué)生仔細(xì)閱讀文章,找出可以表現(xiàn)人物態(tài)度變化的具體的語言和動(dòng)作。最后,讓學(xué)生總結(jié)人物的態(tài)度發(fā)生變化的根本原因是什么,從而引出Money Talks, 供學(xué)生思考?!驹O(shè)計(jì)意圖】通過一系列的活動(dòng)培養(yǎng)學(xué)生學(xué)習(xí)從人物的語言和動(dòng)作探究人物的心理,使學(xué)生進(jìn)一步體會(huì)戲劇語言的魅力,從而對(duì)文章背后所反映的社會(huì)問題進(jìn)行思考,也為下一步的討論環(huán)節(jié)做好鋪墊。

In this class, I have 3 teaching aims, that is, knowledge aims, ability aims and emotion aims.1) Knowledge-Teach students new words and expressions, such as temporary, bleed,sprain choke, first aid, fall ill and so on.-Enable students to have a better understanding for some basic knowledge of first aid.2) Ability-Train students’ speaking, reading and writing abilities by different teaching activities, such as skimming, comprehending, team work, role play, retelling and writing.-Develop students’ reading strategy on how to move general idea to specific information.3) Emotion-Promote students’ awareness of giving first aid.- Cultivate students’ creativities.Then let’s come to my teaching methods and activities.III. Teaching methods and activities:To achieve different teaching aims, various kinds of teaching methods and activities will be adopted throughout this period, such as TBL (task-based learning), skimming, team work, brainstorm and others, which can offer students opportunities to fulfill tasks in which they can use language to achieve a specific outcome.IV. Teaching aids:Computer and blackboardV. Teaching important points:1) Make students have a clear mind for the structure of the text.2) Help students understand the theme of the text.VI. Teaching difficulties:1) So many new words may affect students’ understanding.2) How to get students to know about the functions of the skin and thecauses, characteristics and treatments for different degree burns,and the knowledge about giving first aid.

各小組派代表匯報(bào)。4、教師提出問題組織學(xué)生討論:⑴要想了解更多的綠色食品,了解綠色食品的銷售情況,我們應(yīng)該怎么做?⑵要想了解廣大消費(fèi)者對(duì)綠色食品的態(tài)度,食用綠色食品的意義,是否懂得辨認(rèn)綠色食品,以及什么樣的人群對(duì)此知識(shí)最缺乏等,我們應(yīng)該怎么做?組織學(xué)生匯報(bào)交流。5、做個(gè)“綠色食品”廣告設(shè)計(jì)師。為你喜歡的綠色食品設(shè)計(jì)廣告語,每組推薦一個(gè)。6、讓學(xué)生了解綠色食品認(rèn)證程序。7、綠色食品打“假”隊(duì)員在行動(dòng)。8、向?qū)W生介紹生態(tài)綠色食品基地。三、活動(dòng)總結(jié):通過研究、探討,了解學(xué)生對(duì)綠色食品的態(tài)度。提問:民以食為天,吃,是一個(gè)大問題,如果你的爸爸媽媽讓你到超市買牛奶、方便面等,你會(huì)選擇什么樣的食品?為什么?希望通過今天的學(xué)習(xí),同學(xué)們能夠做到綠色消費(fèi),也希望你們向自己的家人、向周圍的了解學(xué)生對(duì)“無公害食品”、“有機(jī)食品”與“綠色食品”的認(rèn)識(shí)。

分析過焦作市的地理概況和產(chǎn)業(yè)優(yōu)勢后,就需要針對(duì)由于資源枯竭所帶來的問題提出合理化的建議。既然是談經(jīng)濟(jì)轉(zhuǎn)型,就應(yīng)該將話題的范圍明確在這一領(lǐng)域內(nèi)。通過材料3的相關(guān)內(nèi)容,我們了解到焦作市需要在產(chǎn)業(yè)結(jié)構(gòu)調(diào)整、培育新的優(yōu)勢產(chǎn)業(yè)、增強(qiáng)綜合競爭力等三個(gè)整改方針上下功夫。因而引導(dǎo)學(xué)生針對(duì)優(yōu)勢與不足提出建議,以三個(gè)整改方針為基準(zhǔn),衡量建議的可行性是鍛煉學(xué)生解決此類問題的有效途徑。在此我將教會(huì)學(xué)生的是解決問題方法而非案例的內(nèi)容,正所謂“授之以魚,不如授之以漁”。接下來針對(duì)學(xué)生的建議和教材資料分析所羅列的10點(diǎn)整改思路,由學(xué)生自由發(fā)言提出看法,通過教師的指導(dǎo)和學(xué)生的討論,進(jìn)而確定經(jīng)濟(jì)轉(zhuǎn)型建議的具體方案。最后注意將建議與產(chǎn)業(yè)優(yōu)勢相對(duì)照,看建議是否都是圍繞著產(chǎn)業(yè)優(yōu)勢而提出的,這樣做會(huì)加深學(xué)生的印象,通過建議和優(yōu)勢的對(duì)應(yīng)關(guān)系,將不難找出此類問題的解題思路。

【教學(xué)方法】本節(jié)課的教學(xué)知識(shí)點(diǎn)比較瑣碎,學(xué)生學(xué)習(xí)和理解起來有較大的困難。教師在并結(jié)合教材中所引的文獻(xiàn)資料給予必要的點(diǎn)撥,并依據(jù)教材,并在此基礎(chǔ)上拓展教材引用有關(guān)材料,擴(kuò)展學(xué)生的思維,用思考題的形式,有機(jī)地將教材的重點(diǎn)、難點(diǎn)知識(shí)串聯(lián)起來,注意培養(yǎng)學(xué)生史論結(jié)合、論從史出的良好的歷史學(xué)習(xí)品質(zhì)?!緦?dǎo)入新課】秦始皇統(tǒng)一中國后,繼承了商鞅變法的成果和實(shí)踐了韓非子的理論,創(chuàng)立了封建專制主義中央集權(quán)的政治制度,即皇帝制、中央官制和郡縣制,把專制主義的決策方式和中央集權(quán)的政治制度有機(jī)結(jié)合起來。秦始皇首創(chuàng)的專制主義中央集權(quán)的政治體制為我國延續(xù)兩千多年的封建社會(huì)選擇了政治體制的基本模式。西漢王朝建立后,劉邦承襲了秦始皇所開創(chuàng)的統(tǒng)一的封建專制主義中央集權(quán)制。通過綜合概述上節(jié)課內(nèi)容,導(dǎo)入新課。

在同一個(gè)直角坐標(biāo),做出兩個(gè)不同彈簧的F—X圖象,然后進(jìn)行比較。圖象法處理數(shù)據(jù)更為直觀,更容易得出物理變化規(guī)律,且該種方法處理數(shù)據(jù)能更好地減小實(shí)驗(yàn)的偶然誤差。最后老師歸納總結(jié):得出胡克定律:F=KX(K為彈簧的頸度系數(shù))[設(shè)計(jì)意圖:在探究彈力的大小與形變的定量關(guān)系時(shí),由學(xué)生進(jìn)行猜想、實(shí)驗(yàn)和得出規(guī)律,并利用信息技術(shù)計(jì)算機(jī)繪制F—X圖象,充分利用信息技術(shù)資源和物理學(xué)科的整合。能較好地體現(xiàn)以學(xué)生為主的新的教學(xué)理念。對(duì)探究實(shí)驗(yàn)過程教師加以指導(dǎo),使學(xué)生學(xué)會(huì)團(tuán)結(jié)合作、學(xué)會(huì)探究物理規(guī)律;再加上熟練信息技術(shù),更有效地提高學(xué)習(xí)效率。](五)彈力的應(yīng)用(圖片,視頻播放:射箭)[設(shè)計(jì)意圖:讓學(xué)生知道產(chǎn)品設(shè)計(jì)離不開物理理論,做到從實(shí)踐到理論,再從理論到實(shí)踐的學(xué)習(xí)過程。](六)開放式問題(視頻播放:撐桿跳高、跳水);提出問題:通過本節(jié)內(nèi)容的學(xué)習(xí),請(qǐng)同學(xué)們開放式地討論①從形變與彈力知識(shí)去思考,撐桿跳高運(yùn)動(dòng)員跳得這么高的主要原因是什么?②跳水運(yùn)動(dòng)員在空中滯空時(shí)間主要由哪方面決定?

(一)教材的地位與作用本節(jié)教材包括三方面的內(nèi)容,(1)全球氣候在不斷變化之中。(2)全球氣候變化的可能影響。(3)氣候變化的適應(yīng)對(duì)策三方面說明氣候變化及其對(duì)人類活動(dòng)的影響。從標(biāo)準(zhǔn)的要求看,學(xué)習(xí)的重點(diǎn)不在全球氣候變化本身,而是把全球氣候變化看作是客觀存在的事實(shí),從而探討全球氣候變化對(duì)地理環(huán)境及人類活動(dòng)的影響。從資料中可以看出本節(jié)教學(xué)內(nèi)容涵蓋的時(shí)空跨度非常大,思維的鏈索很長很廣,許多問題涉及到學(xué)科的前沿及人類所關(guān)注的熱點(diǎn),因此,本節(jié)課對(duì)學(xué)生而言既有趣味性,又有挑戰(zhàn)性。 (二)教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo):1.通過全球氣候的長期演變圖,學(xué)生了解全球氣候處在波動(dòng)變化之中。2.通過資料認(rèn)識(shí)全球氣候一直處于變化之中并呈現(xiàn)一定變化周期,了解全球氣候變化對(duì)地理環(huán)境及人類活動(dòng)的影響,能夠提出一些氣候變化的適應(yīng)對(duì)策。

六、教學(xué)程序設(shè)計(jì)(“一三五”模式)為了完成這節(jié)課的教學(xué)目標(biāo),我是這樣安排的:第一環(huán)節(jié): (約10分鐘)根據(jù)對(duì)自主探究案的批閱情況,解決學(xué)生的遺留問題具體實(shí)施:投影學(xué)生的自主探究案,讓學(xué)生交流討論,教師點(diǎn)評(píng)。第二環(huán)節(jié): ( 約30分鐘)新課學(xué)習(xí):在“課堂互動(dòng)案”的導(dǎo)學(xué)提綱引領(lǐng)下,完成這節(jié)課的三維教學(xué)目標(biāo)。具體實(shí)施:多媒體輔助教學(xué)、交流討論。第三環(huán)節(jié): (約5分鐘)課堂小結(jié)和布置作業(yè):為了體現(xiàn)課程改革的新理念——學(xué)生是學(xué)習(xí)的主人,我改變傳統(tǒng)的教師總結(jié)為學(xué)生總結(jié)的模式,既強(qiáng)化了學(xué)生所學(xué)的知識(shí),又培養(yǎng)了學(xué)生的歸納和概括能力。作業(yè)分為兩部分:(1)書面作業(yè)p85,1、2、3、4。(2)完成“應(yīng)用提升案”。七、板書設(shè)計(jì)由于多媒體在物理教學(xué)中僅是一種輔助手段,不能完全取代黑板,因此一節(jié)課的主要內(nèi)容和學(xué)生的必要參與還需要借助黑板來幫助。我在這節(jié)課的板書設(shè)計(jì)中突出了主要內(nèi)容,簡潔明了。

學(xué)生回答的方法多樣,讓各小組根據(jù)自己討論出來的方法對(duì)自己實(shí)驗(yàn)出來的紙帶進(jìn)行數(shù)據(jù)處理,并求出加速度,并且將多條紙帶都進(jìn)行處理,同時(shí)提醒學(xué)生對(duì)紙帶的選擇。接著,我會(huì)用多媒體展示重物下落實(shí)驗(yàn)打出來的紙帶,用表格列出一段紙帶上各點(diǎn)的瞬時(shí)速度,準(zhǔn)確畫出v-t圖像,求出加速度,將結(jié)果給予學(xué)生的結(jié)果作對(duì)比,確定出正確結(jié)論。最后讓學(xué)生分析總結(jié):自由落體運(yùn)動(dòng)是初速度為零的勻加速直線運(yùn)動(dòng),而且,多條紙帶算出來的加速度的數(shù)值都接近相等,即加速度在實(shí)驗(yàn)誤差允許范圍內(nèi)是相等的。引出重力加速度,介紹概念、方向及大小。(強(qiáng)調(diào)“同一地點(diǎn)”,讓學(xué)生閱讀教材中一些地點(diǎn)的重力加速度,可以了解重力加速度的大小與緯度有關(guān),緯度越大加速度越大)。學(xué)習(xí)了重力加速度后讓學(xué)生根據(jù)之前學(xué)習(xí)的勻變速直線運(yùn)動(dòng)公式推導(dǎo)出自由落體的運(yùn)動(dòng)規(guī)律。設(shè)計(jì)意圖:讓學(xué)生在學(xué)習(xí)過程中的主體地位和自主觀能動(dòng)性得到充分發(fā)揮,取長補(bǔ)短,培養(yǎng)了學(xué)生的實(shí)驗(yàn)操作能力,又使學(xué)生對(duì)自由落體運(yùn)動(dòng)的性質(zhì)有深刻的印象,從而解決了本節(jié)課第二個(gè)難點(diǎn)。

4、【自主探究】巴山夜雨的成因③材料三:三國時(shí)期,諸葛亮于農(nóng)歷6月的一天,在葫蘆峪設(shè)下伏兵,打算用火攻全殲司馬懿。這一天,晴空萬里暑熱難耐,真乃火攻之良機(jī)。諸葛亮依計(jì)將司馬懿之眾誘入谷中……然而,正當(dāng)大火沖天,司馬懿全軍行將覆滅之時(shí),一場大雨不期而至,大雨澆滅了諸葛亮扶漢反魏的壯志,使他喊出了“謀事在人,成事在天,不可強(qiáng)也”的千古悲歌?!驹O(shè)計(jì)理念】前后呼應(yīng),發(fā)散思維。通過自主探究,學(xué)生各抒己見,完成對(duì)熱力環(huán)流整個(gè)知識(shí)框架的一個(gè)總結(jié),既考查了學(xué)生的課堂學(xué)習(xí)效果,又鍛煉了學(xué)生知識(shí)的遷移能力,并認(rèn)識(shí)生活中的地理規(guī)律,用生動(dòng)的語言拉近學(xué)生與大氣理性知識(shí)的距離,體會(huì)到地理學(xué)科的重要性。【提問】如果將白天換成夏季,將夜間換成冬季,情況又會(huì)怎樣?城市與郊區(qū)之間也存在著熱力環(huán)流——城市風(fēng),它們是怎樣形成的?了解城市風(fēng)的出現(xiàn)有何重要意義?如果地球上在赤道和兩極之間存在熱力環(huán)流,這個(gè)熱力環(huán)流應(yīng)該怎樣?這幾個(gè)問題,請(qǐng)大家課后慢慢思考。

【教學(xué)目標(biāo)】Ⅰ、學(xué)習(xí)理解詩歌語言的暗示性特質(zhì)。Ⅱ、根據(jù)詩歌語言的特質(zhì),進(jìn)行遷移,領(lǐng)略詩歌的精妙之處,給同學(xué)如何鑒賞詩歌提供實(shí)感。㈠、導(dǎo)入:各位同學(xué),有個(gè)成語叫"一字千金"。對(duì)我而言,第一次領(lǐng)略到一個(gè)字的分量,是在小學(xué)三年級(jí)的時(shí)候,一次作文評(píng)析課上。當(dāng)時(shí)我對(duì)自己的文章充滿了期待,希望能得到老師的贊賞。記得老師進(jìn)來后的第一句話是"有一篇文章,我就沖它用了一個(gè)字,我給它打95分。打這樣的高分,對(duì)我來說,是極為難得的。"同學(xué)都充滿了好奇,老師接著說"這個(gè)字就是一個(gè)'悟'字。我們的同學(xué)都說我學(xué)到了,我明白了,我懂得了一個(gè)道理,而這位同學(xué)卻用了一個(gè)'悟'字,難能可貴。"這篇文章不是我的,在羨慕的同時(shí),一個(gè)字在文章中的分量就深深的刻在了我的心上。文學(xué)作品中,一個(gè)字精妙與否,足以決定作品是流光溢彩,還是黯然失色。尤其是我們的古典詩詞,用簡短的幾個(gè)字,造就的卻是豐富的情感與博大的意境。讀后滿口余香,卻是妙處難與君說。這跟詩歌的語言是密不可分的。今天,我們就通過《說"木葉"》一文,對(duì)中國古典詩詞語言特質(zhì)作一番探幽。

教學(xué)過程:(一)導(dǎo)入:課前放《愛的奉獻(xiàn)》歌曲,同時(shí)不斷播放一些有關(guān)“愛”的主題的圖片,渲染一種情感氛圍。師說:同學(xué)們,誰能說說這組圖片的主題應(yīng)該是什么?生(七嘴八舌):母愛,不對(duì)是親情……是友情、還有人與人互相幫助……那組軍人圖片是說保衛(wèi)國家,應(yīng)該是愛國……那徐本禹和感動(dòng)中國呢?…………生答:是關(guān)于愛的方面師說:不錯(cuò),是關(guān)于愛的方面。那么同學(xué)們,今天就以“愛的奉獻(xiàn)”為話題,來寫一篇議論文如何?生答:老師,還是寫記敘文吧。生答:就是,要不議論文寫出來也象記敘文。師問:為什么?生答:老師,這個(gè)話題太有話說了,一舉例子就收不住了,怎么看怎么象記敘文。生答:就是,再用一點(diǎn)形容詞,就更象了。眾人樂。師說:那么同學(xué)們誰能告訴我,為什么會(huì)出現(xiàn)這種問題?一生小聲說:還不是我們笨,不會(huì)寫。師說:不是笨,也不是不會(huì)寫,你們想為什么記敘文就會(huì)寫,一到議論文就不會(huì)了,那是因?yàn)橥瑢W(xué)們沒有明白議論文中的記敘與記敘文中的記敘有什么不同,所以一寫起議論文中的記敘,還是按照記敘文的寫法寫作,這自然就不行了。那好,今天我們就從如何寫議論文中的記敘講起。

培養(yǎng)學(xué)生合作交流意識(shí)和探究問題的能力,這一部分知識(shí)層層遞進(jìn),符合學(xué)生由特殊到一般、由簡單到復(fù)雜的認(rèn)知規(guī)律。4、互動(dòng)探究(1)極限思想的滲透讓學(xué)生閱讀“思考與討論”小版塊.培養(yǎng)學(xué)生的自學(xué)和閱讀能力提出下列問題,進(jìn)行分組討論:a、用課本上的方法估算位移,其結(jié)果比實(shí)際位移大還是小?為什么?b、為了提高估算的精確度,時(shí)間間隔小些好還是大些好?為什么?針對(duì)學(xué)生回答的多種可能性加以評(píng)價(jià)和進(jìn)一步指導(dǎo)。讓學(xué)生從討論的結(jié)果中歸納得出:△t越小,對(duì)位移的估算就越精確。滲透極限的思想。通過小組內(nèi)分工合作,討論交流,培養(yǎng)學(xué)生交流合作的精神,以及搜集信息、處理信息的能力;通過小組間對(duì)比總結(jié),使學(xué)生學(xué)會(huì)在對(duì)比中發(fā)現(xiàn)問題,在解決問題過程中提高個(gè)人能力;
