通過寫文章梗概,培養(yǎng)學(xué)生綜合運(yùn)用語言的能力,學(xué)習(xí)用恰當(dāng)?shù)挠⒄Z描述科學(xué)家的故事。這是本課的教學(xué)難點(diǎn)。教師可以使用完形填空的方式來幫助學(xué)生整理語篇,從而來降低難度。本課的教學(xué)重點(diǎn)的突破方法是:在閱讀前,讓學(xué)生初步了解得出科學(xué)觀點(diǎn)所需要的基本程序,從而輕松而自然地導(dǎo)入文章的閱讀;在閱讀過程中,由易到難設(shè)計(jì)快速閱讀和精讀的問題,層層推進(jìn)各種閱讀活動(dòng),讓學(xué)生對(duì)閱讀內(nèi)容從整體感知到細(xì)節(jié)理解,最后深層讀懂整篇文章,同時(shí)加強(qiáng)閱讀策略的指導(dǎo),讓每個(gè)學(xué)生都主動(dòng)參與課堂教學(xué)活動(dòng),最終達(dá)到提高閱讀能力的目的。Step 4 Post-readingGroup Activities四人小組共同合作,在老師的適當(dāng)指導(dǎo)下,就以下2個(gè)問題展開討論,讓學(xué)生就所知、所學(xué)、所感和所想融入話題,然后抽若干同學(xué)代表作小組發(fā)言。1.

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.

環(huán)節(jié)四 模擬演練 情感升華我將讓同學(xué)們閱讀課本22頁的材料,并按照所提供的步驟,組織學(xué)生舉辦一次模擬聽證會(huì),將學(xué)生分為四個(gè)小組,分別扮演教育局工作人員、人大代表、學(xué)生家長、學(xué)校校長的角色。待學(xué)生們模擬聽證會(huì)結(jié)束后,我將采訪學(xué)生,讓他們談?wù)剠⒓油曷犠C會(huì)后的感受,從而利用角色感悟總結(jié)落實(shí)民主決策的重大意義。這樣,學(xué)生們?cè)谀M演練中,感悟公民要通過各種渠道參與民主決策,是推進(jìn)決策科學(xué)化、民主化的重要環(huán)節(jié)。為學(xué)生將來參與政治生活積累經(jīng)驗(yàn),增強(qiáng)了學(xué)生的主人翁意識(shí)和社會(huì)責(zé)任感。環(huán)節(jié)五 課堂小結(jié) 課后延伸我將用多媒體展示本節(jié)課的知識(shí)框架,并注重引導(dǎo)學(xué)生將今天所學(xué)新知識(shí)與前面知識(shí)聯(lián)系起來,幫助學(xué)生從宏觀上把握各知識(shí)點(diǎn)之間的關(guān)系,有利于學(xué)生理解記憶。另外,適當(dāng)?shù)恼n堂練習(xí)能檢驗(yàn)學(xué)生掌握知識(shí)的情況,因此,課堂小結(jié)后我將讓學(xué)生做一些典型的練習(xí),加深學(xué)生對(duì)本課知識(shí)的理解,同時(shí)為為下一課的學(xué)習(xí)做準(zhǔn)備。

只有對(duì)儒家的價(jià)值作出客觀、公正、全面的評(píng)價(jià),才可能避免陷入文化虛無主義或文化復(fù)古主義的誤區(qū),合理地、充分地開發(fā)利用儒學(xué)乃至整個(gè)國學(xué)的資源為現(xiàn)代社會(huì)服務(wù),為促進(jìn)我國經(jīng)濟(jì)發(fā)展服務(wù)。運(yùn)用所學(xué)知識(shí),談?wù)剬?duì)待儒學(xué)我們應(yīng)該持有的態(tài)度。答案:(1)儒學(xué)是我國傳統(tǒng)文化中一個(gè)非常重要的組成部分。傳統(tǒng)文化具有相對(duì)穩(wěn)定性,它的內(nèi)涵又能夠因時(shí)而變,因此,我們對(duì)待儒學(xué)的正確態(tài)度應(yīng)該是“取其精華,去其糟粕,批判繼承,古為今用”。(2)面對(duì)儒學(xué),我們要辯證地認(rèn)識(shí)它在現(xiàn)實(shí)生活中的作用,分辨其中的精華和糟粕。對(duì)于其中符合社會(huì)發(fā)展要求的、積極向上的內(nèi)容,應(yīng)該繼續(xù)保持和發(fā)揚(yáng),使其為社會(huì)主義現(xiàn)代化建設(shè)服務(wù);對(duì)于其中不符合社會(huì)發(fā)展要求的、落后的、腐朽的東西,必須“移風(fēng)易俗”,自覺地加以改造和剔除。(五)作業(yè)布置傳統(tǒng)文化的作用是什么?如何正確對(duì)待傳統(tǒng)文化?

教師:不同的時(shí)代造就了不同風(fēng)格和不同精神內(nèi)容的詩詞,請(qǐng)同學(xué)們回顧必修一和必修二兩宋中央集權(quán)的加強(qiáng)和經(jīng)濟(jì)的發(fā)展?fàn)顩r。學(xué)生:回憶回答。教師:請(qǐng)同學(xué)們結(jié)合時(shí)代背景和詞的特點(diǎn)理解詞為什么能夠成為宋代文學(xué)的主流形式和標(biāo)志?學(xué)生:兩宋時(shí)經(jīng)濟(jì)重心轉(zhuǎn)移到了南方,商業(yè)發(fā)展打破了時(shí)間和空間的限制,城市繁榮,市民數(shù)量不斷增加。詞的句子長短不齊,便于抒發(fā)感情,并且能夠歌唱,更能適應(yīng)市井生活的需要。于是,詞成為宋代文學(xué)的主流形式和標(biāo)志。教師:宋代文人地位提高,宋詞就是一個(gè)個(gè)時(shí)代的畫卷:大宋的悲歡離合都寫在了里面。除了詞之外,宋代民間還興起了一種新的詩歌形式,即散曲。學(xué)生:回答散曲的發(fā)展階段及特點(diǎn)、元曲的含義、特點(diǎn)。教師:在中國古代詩歌輝煌發(fā)展的同時(shí),也產(chǎn)生了供人們閑來無事消遣的小說。

強(qiáng)調(diào)重力對(duì)生長素分布的影響,為下面的內(nèi)容講解做鋪墊,明確植物出現(xiàn)向光性與生長素分布不均有關(guān)。復(fù)習(xí)舊知識(shí),產(chǎn)生首因效應(yīng),鞏固和加強(qiáng)記憶。通過植物向光性是生長素分布較多而促進(jìn)生長,進(jìn)而提出“對(duì)于植物來說,生長素是不是越多越好”這個(gè)問題,引發(fā)思考,鍛煉思維。說明生長素濃度對(duì)不同器官產(chǎn)生的影響不同,讓學(xué)生對(duì)這一情況有一個(gè)整體印象。結(jié)合數(shù)學(xué)知識(shí)逐步分析圖上各點(diǎn)和各曲線的含義,引導(dǎo)學(xué)生得出不同器官對(duì)生長素濃度的敏感性順序,為解釋橫放植物“S”型生長做鋪墊。通過對(duì)曲線的分析,得出低生長素濃度起促進(jìn)作用,高濃度有抑制作用這種雙重性,并得出其雙重性表現(xiàn)。通過以上的分析和總結(jié),對(duì)橫放植物“S”型生長進(jìn)行解釋,達(dá)到首尾呼應(yīng)的效果。采用“蒙太奇”手法,引申到“太空中,橫放植物將會(huì)如何生長”這個(gè)問題,引發(fā)學(xué)生的聯(lián)想和思考,以這種提問方式結(jié)課為下節(jié)課的開課做了鋪墊,掌握了主動(dòng)權(quán)。

(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?。?、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?

4、種群數(shù)量變化的其他類型我結(jié)合“種群數(shù)量下降”這個(gè)知識(shí)點(diǎn)對(duì)學(xué)生進(jìn)行寓教?,F(xiàn)今的自然界,許多野生生物種群的數(shù)量都在下降,為什么呢?我提供了世界人口近2000年的種群增長曲線,一切都在不言而喻中。現(xiàn)今社會(huì)的主題是呼吁建立和諧社會(huì),作為生物老師,我想它不應(yīng)該僅僅指人與人之間的和諧,也不應(yīng)該僅僅指人與社會(huì)之間的和諧,它更應(yīng)該昭示著人與自然之間的和諧,人類只有學(xué)會(huì)與自然和諧相處,才能在生物圈中享受最大的幸福。6、小結(jié)課程在實(shí)驗(yàn)的大背景下展開,也在實(shí)驗(yàn)的背景中結(jié)束,這里可以呈現(xiàn)出一個(gè)完整的探究思路。同時(shí),學(xué)生思考如何實(shí)現(xiàn)多種預(yù)期過程,相當(dāng)于對(duì)本課進(jìn)行小結(jié)。五、效果預(yù)測課堂上選取的內(nèi)容基于學(xué)生的生活體驗(yàn),創(chuàng)設(shè)的情境能激發(fā)學(xué)生的興趣,設(shè)置的問題符合學(xué)生的認(rèn)知水平,有助于學(xué)生能力的提高,教學(xué)目標(biāo)可以基本實(shí)現(xiàn)。

1.潛在價(jià)值──某種不知名的昆蟲。間接價(jià)值──每個(gè)物種都維系著它們所在的生態(tài)系統(tǒng)的結(jié)構(gòu)和功能。直接價(jià)值──蘆葦是一種重要的造紙?jiān)?;蟬蛻是一種動(dòng)物性藥物;魯班通過觀察某種葉片的葉緣得到啟示,研制出了木工用的鋸;海洋和森林等生態(tài)系統(tǒng)能陶冶情操、激發(fā)創(chuàng)作的靈感。2.主要的困難是,一些發(fā)達(dá)國家(如美國、加拿大和歐盟國家等),拒絕核準(zhǔn)或遲遲不予核準(zhǔn)該議定書。主要爭議的問題是,這些國家擔(dān)心影響本國經(jīng)濟(jì)的發(fā)展和其他國家可能不承擔(dān)相應(yīng)的責(zé)任。例如,美國政府在2003年3月以“減少溫室氣體排放將會(huì)影響美國經(jīng)濟(jì)發(fā)展”和“發(fā)展中國家也應(yīng)該承擔(dān)減排和限排溫室氣體的義務(wù)”為由,宣布拒絕執(zhí)行《京都議定書》。建議世界各國特別是發(fā)展中國家聯(lián)合起來,通過聯(lián)合國大會(huì)和各國的政府以及民間組織等多種途徑,呼吁每年大量產(chǎn)生溫室氣體的發(fā)達(dá)國家率先核準(zhǔn)《京都議定書》(我國政府早在2002年9月就核準(zhǔn)了《京都議定書》)。

一、說教材(一)教材的地位與作用本節(jié)內(nèi)容是本單元知識(shí)結(jié)構(gòu)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(chǎn)生與大氣的熱力狀況、大氣的運(yùn)動(dòng)有密切的聯(lián)系,所以,本課是在綜合前兩節(jié)內(nèi)容的基礎(chǔ)上,闡述常見的天氣現(xiàn)象的成因。在實(shí)際生活中,天氣系統(tǒng)與人們的生產(chǎn)、生活密切相關(guān)。本課所講的內(nèi)容對(duì)于學(xué)生了解天氣變化的最基本因素,普及天氣預(yù)報(bào)知識(shí)具有積極的意義。(二)教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo):⑴從圖片和簡易圖中,知道氣團(tuán)(冷氣團(tuán)、暖氣團(tuán))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(fēng)等幾方面分析各種天氣系統(tǒng)的形成及其氣流特點(diǎn),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(biāo):⑴讓學(xué)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(zāi)害發(fā)生的原因和危害;

(一)教材的地位與作用本節(jié)課是高中地理必修一的最后一節(jié)內(nèi)容,從它的位置安排就可以看出它的定位:即是對(duì)自然地理知識(shí)的總結(jié)、歸納和融合。所以在教學(xué)中應(yīng)充分聯(lián)系學(xué)生已有的舊知識(shí),做好縱向、橫向聯(lián)系,啟發(fā)學(xué)生的思維,培養(yǎng)學(xué)生的地理思維能力。本節(jié)教材從總體上看,包括兩部分內(nèi)容,一是自然地理環(huán)境的基本特征之一──差異性,二是陸地環(huán)境的地域分異規(guī)律。陸地環(huán)境的地域分異規(guī)律是通過自然帶的地帶性分布規(guī)律來體現(xiàn)的。本節(jié)課主要是以地理分布規(guī)律為中心內(nèi)容,在教學(xué)時(shí),要突出讀圖分析、推斷的環(huán)節(jié),而且所提供的圖表、資料必須有利于學(xué)生分析、推理能力的培養(yǎng)和提高。(二)教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo):1.認(rèn)識(shí)和理解自然地理環(huán)境的地域差異特點(diǎn)2.了解地理環(huán)境差異性的分異規(guī)律
