This unit is about history and traditions. From the opening page, we can know that this unit will introduce the history and traditions around the world. As Marcus Garvey says “A people without the knowledge of their past history, origin and culture is like a tree without roots”, it is important for students to realize the importance and value of knowing the history and traditions and their further meanings. And this part ( listening and speaking ) is divided into two parts: Part A---share views on historic sites, Part B ---talk about a visit to a historic tourist destination. By talking with a foreigner, the speakers introduce the historic attractions and their cultures. Part A is that William, a British student, who was going to visit the Confucius Temple and a Chinese student, Xiao Kong, who was going to the Confucius Temple to meet with the members of the research group, went together and exchanged their views on the Confucius Temple, Confucius, Confucius' descendants and Confucius' educational thoughts. Part B is a conversation between Xiao Yan, a youth hostel receptionist and Paul, a backpacker about the feelings and experience after visiting the Chinese famous tourist attraction Pingyao.1. Guide students to understand the content of listening texts in terms of the whole and key details; 2. Cultivate students' ability to guess the meaning of words in listening; discuss with their peers how to talk about historic spots and great person.3. Instruct students to use functional sentences of showing one’s excitement, surprise and disappointment.1. Guide students to understand the content of listening texts in terms of the whole and key details; 2. Cultivate students' ability to discuss with their peers the related topics.3.

1、外匯與外幣的關系:(1)外匯包括外幣,但外匯不等于就是外幣。外幣是指外國的貨幣,包括外國的紙幣、鑄幣;外匯通常是以外國貨幣表示的用于國際間結算的支付手段,具體包括外幣、外幣有價證券、外幣支付憑證等。(2)外幣屬于外匯的范圍,但不能把二者等同起來。通常情況下,只有可以自由兌換的外幣才是外匯,因為外匯的實質是國際支付手段,如果某種貨幣不能自由兌換,它就不能成為國際支付手段。外匯執(zhí)行的 主要是貨幣的支付手段的職能。(3)持有外匯意味著對外匯發(fā)行國擁有債權。持有外匯過多,一方面意味著國際支付能力強和有可能對外匯發(fā)行國施加影響;另一方面則意味著大量該由本國享受的資源,被借給外國利用,并要承擔外匯貶值的風險。2、關于幣值變化的分析:(1)對貨幣升值的具體分析:一個國家的貨幣升值(上浮)后,同量的這種貨幣能比以前換 取更多的他國貨幣,買到更多的他國商品。
一、說教材: 《〈詩經〉兩首》是初中語文教材8年級下冊第3單元的課文,單元教學重點旨在讓學生了解古代詩歌的發(fā)展進程、思想感情及其藝術效果,提高學生的詩歌鑒賞能力。本次課將要學習的《關雎》和《蒹葭》兩首詩都是詩經的名篇,兩首詩在主題內容上是相似的,情感基調是相近的,同時在藝術手法方面也都運用了重章疊唱和賦比興的方式。 2、教學目標根據本課特點,現(xiàn)將教學目標擬訂如下:⑴知識目標:了解《詩經》的基本常識,體會賦、比、興的藝術手法,掌握四言詩的誦讀節(jié)拍。⑵能力目標:培養(yǎng)學生結合注釋,讀懂詩作的能力。背誦課文,培養(yǎng)和提高學生準確把握作品的藝術形象和思想感情的能力。⑶情感目標:使學生了解我國古代勞動人民對真摯愛情的向往,陶冶高尚的情操。
首先引導回顧細胞質內各個細胞器的分工協(xié)作、產生分泌蛋白的過程;同時思考:為什么這些細胞器可以這樣有條不紊的密切協(xié)作?這中間有沒有專門起協(xié)調和控制作用的部門?從而導入本節(jié)內容。通過學生小組討論及師生共同分析“資料分析”中的4個實驗,總結出細胞核的功能,即細胞核是遺傳信息庫,控制細胞代謝和遺傳的功能。在此基礎上,向學生舉出克隆羊多莉的實例,加強理解。設問:那么細胞核為什么能成為細胞代謝和遺傳的控制中心?要弄清這個問題,我們必須從細胞核的結構中尋找答案,從而引出細胞的結構。在這部分,引導學生思考以下幾個問題:(1)細胞核能控制細胞的遺傳,說明其應該有什么物質?(2)含有DNA的結構如線粒體、葉綠體,它們的外面都有什么相同的結構?(3)細胞核能控制細胞,肯定能與外界聯(lián)系,如何能辦到?(4)學習RNA的分布時,RNA主要分布在細胞質,少量還分布在哪里呢?
②與學牛的?;罱涷炏嚓P,有利激發(fā)學列的興趣。⑧利用多媒體讓學牛通過觀看、比較、討論,加深理解f-J利掌握細胞內的牛要細胞器的結構及其功能。④學牛白豐學習,豐動建構新知識。⑤為完成后面的達標圖表做充分的準備。4、概括反饋:①設訃達標表格,引導學牛完成。②應用該表格進行小結。③推薦相關網站,以解決課后遇到的附加題。這樣設置的理由是①通過完成表格,歸納各種細胞器的結構和功能,使學牛更好的掌握本節(jié)課的內容。②培養(yǎng)學牛的分析問題和歸納總結的能力③培養(yǎng)學牛的競爭意識和團隊合作精神。④拓展了教育資源,為學牛提供了一個白豐學習的空間。[課堂小結]請4-5位學牛來總結本節(jié)課的學刊內容和白己掌握的情況。請教師重新出示“八種細胞器的比較表”和“植物細胞和動物細胞的比較表”對本節(jié)內容的知識點、重點、難點進行總結。
(1)問題串設計:①選材:選擇什么細胞做材料?②為什么選擇哺乳動物成熟的紅細胞做實驗材料?(在教師的指導下討論分析)③怎樣才能獲得細胞膜?(教師講授)(2)指導學生觀看多媒體播放教參CD中的這個實驗,同時教師加以講解(3)學生分組實驗(4)總結實驗并加以評價設計意圖:體會實驗材料的正確選擇對于科學研究的重要性,提高學生科學研究素養(yǎng)。學生在已有知識的基礎上思考,嘗試找出實驗的原理,實現(xiàn)親身體驗、自主思考的的過程,這樣加深學生的印象。培養(yǎng)學生拓展遷移的能力,使學生認識先進的生物學研究儀器。環(huán)節(jié)3.細胞膜的功能(1)學生自主學習并歸納總結:P42(2)展示圖片加強理解:圖片(3)討論:聯(lián)系生活實際,列舉現(xiàn)實生活中有什么東西與細胞膜的功能相近?設計意圖:提高學生自主學習的能力;注重與現(xiàn)實生活的聯(lián)系,引導學生利用類比的方法解決問題,便于學生理解和掌握。環(huán)節(jié)4. 植物細胞的細胞壁
一、說教材(一)教材的地位與作用本節(jié)內容是本單元知識結構中重要的一環(huán),具有承上啟下的作用。由于各種天氣現(xiàn)象的產生與大氣的熱力狀況、大氣的運動有密切的聯(lián)系,所以,本課是在綜合前兩節(jié)內容的基礎上,闡述常見的天氣現(xiàn)象的成因。在實際生活中,天氣系統(tǒng)與人們的生產、生活密切相關。本課所講的內容對于學生了解天氣變化的最基本因素,普及天氣預報知識具有積極的意義。(二)教學目標(1)知識與技能目標:⑴從圖片和簡易圖中,知道氣團(冷氣團、暖氣團)的概念;鋒的概念與分類;低壓(氣旋)、高壓(反氣旋)、高壓脊、低壓槽的概念。 ⑵從氣溫、氣壓、濕度、降水、風等幾方面分析各種天氣系統(tǒng)的形成及其氣流特點,并綜合出各種天氣系統(tǒng)控制下的天氣狀況。⑶知道低壓槽和高壓脊概念及在圖上的表示方法。(2)過程與方法目標:⑴讓學生能閱讀和簡單分析天氣圖,解釋天氣變化現(xiàn)象;⑵用案例說明氣象災害發(fā)生的原因和危害;
下面是對以高技術產業(yè)為主的新工業(yè)區(qū)的內容進行講解,教材以美國“硅谷”為例,首先談的是高技術工業(yè)的特點,然后講述的是“硅谷”的發(fā)展條件,由于教學模式與意大利新工業(yè)區(qū)的內容基本一致,這里就不再贅述了。接下來教材中提到的與之對照的案例同樣是以高技術產業(yè)而聞名的中關村,由于中關村在國內的知名度較高,一般學生都有所了解,因此不妨讓學生談談自己的看法:對于高新技術產業(yè)的發(fā)展有何建議,相對于發(fā)展較為成功的“硅谷”我們需要學習的方面又是哪些?案例中最后一個問題很值得深省,我國的新工業(yè)區(qū)到底怎樣做才能夠獲得成功,簡單的模仿下我們缺少的又是什么?這個問題可以作為拓展,讓學生寫一篇簡短的論文作為課后作業(yè)。最后做以簡單的課堂小結。本節(jié)內容的教學可能會相對繁雜,而案例之間的分析過程又過于雷同,所以難免枯燥。在處理這個問題上,我將盡量做到詳略得當,主要培養(yǎng)學生的自主學習能力。
1.做學問之前首先學會做人2.知識文化修養(yǎng)和思想道德修養(yǎng)的關系三.追求更高的思想道德目標㈤ 說教學評價和反思:1.這節(jié)課主要是以學生為主體,老師為主導,讓學生充分發(fā)表自己的看法,把理論的知識結合在實際的日常生活中,鼓勵學生充分發(fā)表自己的意見,能調動學生學習的積極性,達到教學目的。這節(jié)課學生討論,發(fā)言的機會很多,但由于我校的學生的基礎薄弱,在發(fā)言時難免偏離老師引導的方向,甚至出現(xiàn)毫不相干的說法,由于本人經驗不夠此時如何去引導他們可能做的還不夠好。2.新課程的教學,如何突破書本知識的局限,延伸更深層次的內容是一個難題。本節(jié)課在知識的處理上,把道德的重要性與道德的層次兩個知識點補充了進去,目的是讓學生在學習之前有一個情感的鋪墊,從而更好地達到教學目標。
一、教學理論依據及設計理念以新課程理念和新課標為指針,依據建構主義理論、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。
板書:多民族文化對中華文化的意義師:中華民族是多民族的共同體,中華文化呈現(xiàn)多種民族文化的豐富色彩。中華各民族的文化,既有中華文化的共性,又有各自的民族特性。它們都是中華文化的瑰寶,都是中華民族的驕傲。各兄弟民族文化相互交融、相互促進,共同創(chuàng)造了中華文化。各族人民對共同擁有的中華文化的認同感和歸屬感,顯示了中華民族厚重的文化底蘊和強大的民族凝聚力。問題探究8溫家寶總理在美國會見華僑時滿懷深情地說,中國已解決了香港問題和澳門問題,洗刷了百年恥辱,現(xiàn)在剩下一個臺灣問題,“這一灣淺淺的海峽是我們最大的鄉(xiāng)愁、最大的國殤”。用有關知識分析:為什么“這一灣淺淺的海峽是我們最大的鄉(xiāng)愁、最大的國殤”?生1:臺灣是中國的一部分,臺灣各族人民是中華民族的一部分,臺灣文化歸屬于中華文化。生2:傳統(tǒng)的民族文化是維系民族生存和發(fā)展的精神紐帶。
師:同學們這個暑假過得真不錯呀,都有自己最開心的日子。同學們經歷的這些活動,讓你們自己長了知識,豐富了閱歷,你們今天的介紹,也讓我和更多的同學大開了眼界。由此可見,在今天,通過親身參與、實踐,通過網絡、電影,通過交流發(fā)言,大家獲得了許多新的信息、知識,增強了對祖國美好河山的熱愛、對科技的向往和異國的友誼。同學們信息交流的過程,實際上也是文化傳播的過程。板書課題:第二課時文化在交流中傳播話題導入討論話題:如何建設文明校園?(課前準備:要求同學們仔細觀察、了解關于校園文明現(xiàn)象的問題,并就如何建設文明校園提出自己的建議。教師可按自然組,讓學生推選一名代表發(fā)言,就校園文明方面談談存在的問題和不足,或提出一些中肯的改進意見)(學生交流)生1:建設文明校園,首先要凈化語言環(huán)境,我們學校不少同學愛說臟話,與文明校園很不相稱。
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?!保t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。
