⑦在我看來, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand,70% think space is worth exploring because we have benefited a lot from it,such as using satellites for communication and weather forecast. What’s more,with further space research,we may solve the population problem by moving to other planets one day. Also,space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

二、說學(xué)生本屆高一學(xué)生經(jīng)過了三年初中課改,在心理上,他們渴望表現(xiàn)的欲望和自主探究的欲望比較強(qiáng)烈,對(duì)有興趣的知識(shí)表現(xiàn)出高度地?zé)崆椋⒕哂幸欢ǖ膱F(tuán)結(jié)協(xié)作能力,但還是應(yīng)該正視一個(gè)并不樂觀的現(xiàn)實(shí)——在寫作方面,學(xué)生知識(shí)還停留在簡(jiǎn)單的記敘及表達(dá)方式綜合運(yùn)用上,至于巧妙構(gòu)思、謀篇布局很是空白。即便已經(jīng)經(jīng)過高中一個(gè)學(xué)期的學(xué)習(xí),但還是有大部分學(xué)生依然基礎(chǔ)較為薄弱,甚至出現(xiàn)不知從何下筆的現(xiàn)象。三、說教法與學(xué)法“老師搭臺(tái),學(xué)生唱戲”1、教法:本課將安排兩課時(shí)(一課時(shí)學(xué)習(xí)一課時(shí)練筆),采用 PPT 多媒體課件教學(xué),嘗試用角色扮演法、圖片展示法和多媒體教學(xué)等方法,教學(xué)中應(yīng)該重視學(xué)生的參與性和探究性。2、學(xué)法:學(xué)生應(yīng)該充分利用多角度創(chuàng)設(shè)的學(xué)習(xí)情境來激發(fā)自身學(xué)習(xí)的興趣和熱情,分組討論,小組互助等形式讓學(xué)生積極自主參與、進(jìn)行問題探究學(xué)習(xí)。理論依據(jù):建構(gòu)主義理論“學(xué)生是學(xué)習(xí)的中心”的闡釋,教師應(yīng)該做學(xué)生主動(dòng)建構(gòu)意義的幫助者、促進(jìn)者。

1)他們?cè)诔踔械纳飳W(xué)學(xué)習(xí)中已具備了一定的關(guān)于光合作用的基礎(chǔ)知識(shí),也做過“綠葉在光下制造淀粉”這個(gè)實(shí)驗(yàn)。2)他們具備物質(zhì)轉(zhuǎn)變和能量變化等相關(guān)的化學(xué)知識(shí)。3)在前面的《降低化學(xué)反應(yīng)活化能的酶》一節(jié)的學(xué)習(xí)中已經(jīng)學(xué)習(xí)過簡(jiǎn)單的對(duì)照實(shí)驗(yàn)和相關(guān)的實(shí)驗(yàn)設(shè)計(jì)原則,使本節(jié)課最后的實(shí)驗(yàn)設(shè)計(jì)得以順利進(jìn)行。4)他們具有一定的 分析問題的能力,實(shí)施問題探究教學(xué)是可行的。三、教法和學(xué)法根據(jù)上述對(duì)教材和學(xué)生的分析,本節(jié)采用以下教法和學(xué)法:1)實(shí)驗(yàn)法:以實(shí)驗(yàn)說明結(jié)論。生物學(xué)的教學(xué)就是實(shí)驗(yàn)的教學(xué)過程,實(shí)驗(yàn)的展示形式有學(xué)生分組實(shí)驗(yàn)、老師示范實(shí)驗(yàn)、動(dòng)畫和圖片演示實(shí)驗(yàn)等,讓實(shí)驗(yàn)現(xiàn)象說明問題,而不是直接讓學(xué)生記住結(jié)論。2)問題探究教學(xué)發(fā):以問題引發(fā)興趣。整個(gè)教學(xué)過程要設(shè)置好問題,層層展開,層層遞進(jìn),讓新知識(shí)與舊知識(shí)融為一個(gè)整體,讓學(xué)生在步步上升中攀登到知識(shí)的頂峰。3)比較學(xué)習(xí)法,同時(shí)采用多媒體輔助教學(xué),解決光合作用抽象的過程。

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?gòu)睦碚摰綄?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?gòu)男巫兣c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?

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(jiǎn)潔明了。

當(dāng)代社會(huì)生活的變化比以往任何時(shí)代都要快。語(yǔ)言尤其是詞匯記錄了這些發(fā)展變化,因而也涌現(xiàn)了大量的新詞新語(yǔ)。據(jù)統(tǒng)計(jì),近幾年每年大約要出現(xiàn)1000個(gè)左右的新詞新語(yǔ),而字典、詞典的多次修訂、增補(bǔ)就反映了這種情況。但相對(duì)來說,也有一些流行語(yǔ)又逐漸受到冷遇,甚至退隱。為了更好的對(duì)新詞新語(yǔ)與流行文化作一番檢視與探究,那讓我們考察一下它們是怎么產(chǎn)生的吧?老師先給同學(xué)們列舉四種途徑:大屏幕3。同學(xué)們能再舉出以上途徑的一些例子嗎?老師列舉(4)其實(shí)不只這些,那還有哪些途徑呢?找同學(xué)說并舉例。說的非常好,請(qǐng)同學(xué)們看老師的例子,總結(jié)(5)。從新詞新語(yǔ)的產(chǎn)生途徑可以看出,這些鮮活得像畫一樣的新詞就是這個(gè)時(shí)代跳動(dòng)的血小板,它涉及當(dāng)代社會(huì)的重大事件、現(xiàn)象與時(shí)弊,以及人們?nèi)粘I畹母鱾€(gè)層面如人生意義、生活方式、愛情、友情、就業(yè)、消費(fèi)、時(shí)尚等,時(shí)代性強(qiáng),傳播面廣,反映著當(dāng)代社會(huì)時(shí)局與人們文化心態(tài)的變化。

4、【自主探究】巴山夜雨的成因③材料三:三國(guó)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(wàn)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(chǎng)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(yǔ)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?!咎釂枴咳绻麑滋鞊Q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。

(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(zhǎng)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(zhǎng)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。

(四)、活動(dòng)交流,體驗(yàn)科學(xué)通過資料分析討論以下三個(gè)問題:1、你知道愛滋病的傳播途徑嗎?2、如何預(yù)防愛滋???3、我們應(yīng)如何對(duì)待愛滋病患者?面對(duì)艾滋病我們能做些什么?從而進(jìn)入情感態(tài)度的教育。除此之外,我還設(shè)計(jì)一個(gè)開放性的作業(yè)“向全社會(huì)為關(guān)注艾滋病設(shè)計(jì)一個(gè)宣傳廣告”(形式不限,漫畫、板書、倡議書等),讓學(xué)生把愛心付諸于實(shí)際行動(dòng)。在此基礎(chǔ)上引出“免疫學(xué)的應(yīng)用”從免疫預(yù)防、免疫治療、器官移植三個(gè)方面講述,讓學(xué)生充分體驗(yàn)到知識(shí)和社會(huì)生活的緊密聯(lián)系,讓他們不在感到科學(xué)是那么的遙遠(yuǎn),而是可愛的有用的。通過交流,讓同學(xué)們體會(huì)到合作的魅力和重要性,進(jìn)一步培養(yǎng)合作意識(shí)和合作能力。最后我設(shè)計(jì)一個(gè)資料搜集,讓同學(xué)們選一個(gè)感興趣的主題利用電腦在網(wǎng)上搜集有關(guān)資料。主題:1、你知道世界艾滋病日嗎?歷年的主題是什么?開展世界艾滋病運(yùn)動(dòng)有什么意義?

二、應(yīng)用生長(zhǎng)調(diào)節(jié)劑的注意事項(xiàng)1、效果不穩(wěn)定。2、使用時(shí)期。3、使用濃度和方法。4、使用生長(zhǎng)調(diào)節(jié)劑僅是葡萄栽培管理的輔助手段,不能盲目孤立地依賴生長(zhǎng)調(diào)節(jié)劑。生2:我們小組查的資料是關(guān)于小麥?zhǔn)褂蒙L(zhǎng)調(diào)節(jié)劑。小麥應(yīng)用植物生長(zhǎng)調(diào)節(jié)劑,可以調(diào)節(jié)植株的生長(zhǎng)發(fā)育,具有控旺促壯、增強(qiáng)抗逆性、增加粒重、提高產(chǎn)量并有利于優(yōu)質(zhì)、早熟等多重效果。生3:我找了一篇生長(zhǎng)調(diào)節(jié)劑對(duì)矮牽牛大型穴盤生產(chǎn)。師:上面三位同學(xué)利用課下的時(shí)間,在網(wǎng)上查的三段文字都相當(dāng)?shù)牟诲e(cuò),大家可以從中學(xué)到一些書本上沒有的知識(shí),請(qǐng)大家結(jié)合剛剛?cè)煌瑢W(xué)的三段文字以及自己平時(shí)所積累的知識(shí),討論以下幾個(gè)問題。師:你知道哪些農(nóng)產(chǎn)品在生產(chǎn)過程中使用了植物生長(zhǎng)調(diào)節(jié)劑?師:哪些水果在上市前有可能使用了乙烯利?師:生產(chǎn)過程中施用植物生長(zhǎng)調(diào)節(jié)劑,會(huì)不會(huì)影響農(nóng)產(chǎn)品的品質(zhì)?師:如果你是水果銷售員,面對(duì)半青不熟的水果,你認(rèn)為應(yīng)當(dāng)使用乙烯利催熟嗎?作為一個(gè)消費(fèi)者,你又怎么看?

【情感態(tài)度及價(jià)值觀】 通過創(chuàng)設(shè)探究情境,展示典型顯示案例激發(fā)思考,與學(xué)生共同感受當(dāng)前區(qū)域經(jīng)濟(jì)一體化與經(jīng)濟(jì)全球化浪潮的沖擊,以及當(dāng)前我國(guó)、我省發(fā)展的機(jī)遇、成就和危機(jī),培養(yǎng)學(xué)生的時(shí)代感和使命感。五、重點(diǎn)難點(diǎn)【重點(diǎn)】1、產(chǎn)業(yè)轉(zhuǎn)移的影響因素2、產(chǎn)業(yè)轉(zhuǎn)移對(duì)區(qū)域地理環(huán)境的影響【難點(diǎn)】1、如何從圖文材料中分析出影響產(chǎn)業(yè)轉(zhuǎn)移的主要因素2、產(chǎn)業(yè)轉(zhuǎn)移對(duì)產(chǎn)業(yè)遷出區(qū)和移入?yún)^(qū)的不同影響六、教學(xué)方法1、材料分析法。提供分層次的問題與材料,并進(jìn)行方法指導(dǎo),學(xué)生通過思考和討論自行分析發(fā)現(xiàn)知識(shí)、構(gòu)建知識(shí)。使不同層次的學(xué)生均有發(fā)展。這是本節(jié)設(shè)計(jì)主要采用的教學(xué)方法。2、合作探究法3、多媒體教學(xué)法七、 教學(xué)過程(一) 引入 :假如某同學(xué)買彩票中大獎(jiǎng),想投資生產(chǎn)面臨幾項(xiàng)選擇1、投資高端智能手機(jī)制造還是普通服裝廠?2、廠址選擇在濮陽(yáng)市還是南樂縣?

d.某物體沿直線向東運(yùn)動(dòng),原來的速度是5m/s,2s后速度減小到3m/s,求2s內(nèi)物體速度變化。④如何探究物體作勻速圓周運(yùn)動(dòng)時(shí),在Δt時(shí)間內(nèi)的速度變化?分析:有了同一直線上速度變化的鋪墊后,討論物體做勻速圓周運(yùn)動(dòng)速度的變化就比較自然了,為了給向心加速度方向的學(xué)習(xí)打好基礎(chǔ),可以通過小組協(xié)作,進(jìn)一步完成下列思考題,使同學(xué)們認(rèn)識(shí)到:時(shí)間間隔起短,速度變化的方向起接近半徑方向。(多媒體屏幕投影)a.物體沿半徑為1m的軌道做勻速圓周運(yùn)動(dòng),線速度大小為,求1s內(nèi)物體速度變化并畫出1s內(nèi)速度變化的示意圖。b.分別求出上題中物體在0.5s、0.25s內(nèi)速度變化并畫出相應(yīng)的示意圖。由于沒有辦法直接利用實(shí)驗(yàn)來驗(yàn)證速度變化的方向,所以,我們采用提供思考題的方法,引導(dǎo)同學(xué)在合作學(xué)習(xí)、自主探究中完成。有了速度變化的研究為鋪墊,加速度的方向問題就迎刃而解了。
