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.

3、評:以評促行。(6分鐘)高中生的年齡特點決定了他們非常重視別人對自己的評價,渴望得到他人的肯定與鼓勵。(所以我在班上組織一個活動:讓同學們評選出班上“講文明懂禮貌的文明之星”、“勤思考善創(chuàng)新的學習之星”(先讓同學推舉大家都認同的4位同學,然后對他們進行投票,投票結(jié)果將在下堂課上公布)以此活動來激發(fā)同學們用實際行動做民族精神的踐行者和傳播者。)4、唱:以情激行。(2分鐘)在課程內(nèi)容講授結(jié)完畢后,組織全班同學跟著音樂高唱孫楠的《紅旗飄飄》,生化情感,激發(fā)同學們的愛國情感。五、課堂拓展(請同學們各展才華:課后讓同學們各自準備一個項目以體現(xiàn)民族精神。(項目形式是:或作文、書畫;或剪紙、或歌曲小品)……讓同學們用實際行動祝愿我們偉大的祖國更加繁榮昌盛!讓我們的民族精神代代相傳?。?/p>

生2:每逢清明,或其他一些死者的紀念日,人們總要為死去的親人燒紙錢。這幅漫畫由燒紙錢演變?yōu)闊凹译姟?,說明隨著社會環(huán)境的變化,人們根深蒂固的一些封建思想,還在影響著人們的生活。要花大力氣去破除封建迷信活動。師:說到底,算命、燒紙錢是封建迷信活動,從文化角度來說,是落后文化。我們一起來看看在現(xiàn)實生活中,還有哪些落后文化在影響著人們的生活。生1:在一些邊遠落后地區(qū),大人小孩生了病,不是看醫(yī)生,而是讓巫婆神漢來治,結(jié)果往往耽誤了診療時間,有的甚至還丟掉了性命。生2:“重男輕女”“多子多?!?,紅白事大操大辦現(xiàn)象在有些地方還很嚴重。師:這些落后文化都有哪些共同特征?在你看來,這些現(xiàn)象有哪些危害?生3:這些落后文化,在內(nèi)容上帶有迷信、愚昧、頹廢、庸俗等色彩,在形式上常常以傳統(tǒng)習俗的形式表現(xiàn)出來,如人們常見的看相、算命、測字、看風水等。它會麻痹人的意志,使人消極、悲觀、絕望,對理想、前途、信念喪失信心;破壞社會的風氣。

一、教材分析文化市場和大眾傳媒的發(fā)展,給我們的文化生活帶來了許多可喜的變化。但是,文化市場的自發(fā)性和傳媒的商業(yè)性也引發(fā)了令人憂慮的現(xiàn)象。文化生活有“喜”也有“憂”,讓我們歡喜讓我們憂。面對形式多樣的文化生活,置身于文化生活的海洋之中,在文化生活中如何選擇、怎樣作出正確的選擇是亟待向?qū)W生解決的問題。二、學情分析高二學生處于世界觀、人生觀和價值觀形成的關鍵時期,身心迅速發(fā)展,自我意識和獨立性較強,社會公共生活空間范圍越來越大,并且開始理性地思考社會和人生的重大問題,他們可塑性強,但情緒仍然不穩(wěn)定,有多變性,容易沖動或偏激,迫切需要提升思想意識,加強方法論的指導,使其在紛繁復雜的文化生活中能夠進行正確的判斷與選擇。如果我們的學生不能把握正確的航向,是非觀念模糊,良莠不分,就會陷入落后文化和腐朽文化的泥沼而不能自拔,甚至造成無法挽回的惡果。

一、教學理論依據(jù)及設計理念以新課程理念和新課標為指針,依據(jù)建構(gòu)主義理論、學科探究理論和多元智力理論,采用探究式的教學模式來組織實施本節(jié)課的教學。學生成為課堂的主體和知識的主動構(gòu)建者。通過創(chuàng)設多種情境,讓學生積極參與、體驗、感悟,主動獲得新知,并逐步提高學生發(fā)現(xiàn)問題、分析問題和解決問題的能力。教師從課堂的主宰變?yōu)檎n堂的主導,是學生學習活動的組織者、引導者和合作者。教學過程是一個發(fā)散式的學生自主學習的過程。采用自主、合作、探究式的教學方式,讓學生有多元選擇,激發(fā)他們的潛能,發(fā)展他們的個性。二、教材分析1.教材的地位與作用:本框題是《生活與哲學》第二單元《探索世界與追求真理》第六課“求索真理的歷程”的第二節(jié)內(nèi)容。本單元的核心問題是如何看待我們周圍的世界,該問題也是《生活與哲學》整本書的核心問題之一。

二、說學生本屆高一學生經(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烈,對有興趣的知識表現(xiàn)出高度地熱情,并具有一定的團結(jié)協(xié)作能力,但還是應該正視一個并不樂觀的現(xiàn)實——在寫作方面,學生知識還停留在簡單的記敘及表達方式綜合運用上,至于巧妙構(gòu)思、謀篇布局很是空白。即便已經(jīng)經(jīng)過高中一個學期的學習,但還是有大部分學生依然基礎較為薄弱,甚至出現(xiàn)不知從何下筆的現(xiàn)象。三、說教法與學法“老師搭臺,學生唱戲”1、教法:本課將安排兩課時(一課時學習一課時練筆),采用 PPT 多媒體課件教學,嘗試用角色扮演法、圖片展示法和多媒體教學等方法,教學中應該重視學生的參與性和探究性。2、學法:學生應該充分利用多角度創(chuàng)設的學習情境來激發(fā)自身學習的興趣和熱情,分組討論,小組互助等形式讓學生積極自主參與、進行問題探究學習。理論依據(jù):建構(gòu)主義理論“學生是學習的中心”的闡釋,教師應該做學生主動建構(gòu)意義的幫助者、促進者。

當代社會生活的變化比以往任何時代都要快。語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。據(jù)統(tǒng)計,近幾年每年大約要出現(xiàn)1000個左右的新詞新語,而字典、詞典的多次修訂、增補就反映了這種情況。但相對來說,也有一些流行語又逐漸受到冷遇,甚至退隱。為了更好的對新詞新語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?老師先給同學們列舉四種途徑:大屏幕3。同學們能再舉出以上途徑的一些例子嗎?老師列舉(4)其實不只這些,那還有哪些途徑呢?找同學說并舉例。說的非常好,請同學們看老師的例子,總結(jié)(5)。從新詞新語的產(chǎn)生途徑可以看出,這些鮮活得像畫一樣的新詞就是這個時代跳動的血小板,它涉及當代社會的重大事件、現(xiàn)象與時弊,以及人們?nèi)粘I畹母鱾€層面如人生意義、生活方式、愛情、友情、就業(yè)、消費、時尚等,時代性強,傳播面廣,反映著當代社會時局與人們文化心態(tài)的變化。

在學習語文經(jīng)驗交流會上,季老師舉著我的《采花釀蜜集》,對大家說:“人日積月累辛勤采擷,終于釀出了知識的瓊漿。大家都應這樣,爭做知識的富戶??!”老師有點激動,低低地爬在鼻梁上的眼鏡突然滑了下來,正好落在那集子上。大家笑了,季老師也笑了。就這樣,我的寫作有了進步,好幾篇作文登上了班級《學作園地》。從此,我愛上了語文,更深深地愛上了季老師。高中升學考前那個星期天的夜晚,季老師舊病復發(fā),累倒了。半夜,老師們把他送進了公社衛(wèi)生院。第二天,同學們都悄悄去衛(wèi)生院看望。我去的時候,季老師正在掛滴流??墒?,下午季老師又出現(xiàn)在講臺上,他臉色憔悴,聲音沙啞……我手捧《采花釀蜜集》走近季老師,思緒的溪水從遠方流了回來?!凹纠蠋煛?,我把本子捧給老師,深情地叫了聲。季老師接過本子,仔細翻閱著,臉上露出了笑容,像是聞到了郁郁芳香的蜜汁似的。“進步不小呀!”季老師說著,又在本子扉頁上題了

1)他們在初中的生物學學習中已具備了一定的關于光合作用的基礎知識,也做過“綠葉在光下制造淀粉”這個實驗。2)他們具備物質(zhì)轉(zhuǎn)變和能量變化等相關的化學知識。3)在前面的《降低化學反應活化能的酶》一節(jié)的學習中已經(jīng)學習過簡單的對照實驗和相關的實驗設計原則,使本節(jié)課最后的實驗設計得以順利進行。4)他們具有一定的 分析問題的能力,實施問題探究教學是可行的。三、教法和學法根據(jù)上述對教材和學生的分析,本節(jié)采用以下教法和學法:1)實驗法:以實驗說明結(jié)論。生物學的教學就是實驗的教學過程,實驗的展示形式有學生分組實驗、老師示范實驗、動畫和圖片演示實驗等,讓實驗現(xiàn)象說明問題,而不是直接讓學生記住結(jié)論。2)問題探究教學發(fā):以問題引發(fā)興趣。整個教學過程要設置好問題,層層展開,層層遞進,讓新知識與舊知識融為一個整體,讓學生在步步上升中攀登到知識的頂峰。3)比較學習法,同時采用多媒體輔助教學,解決光合作用抽象的過程。
