為使學生對知識達到深化理解、鞏固提高的效果,我結(jié)合兩個討論題專門設(shè)計了一組即時訓練題,做完后,屏幕展示匯總,以及時鞏固新知。然后,進行當堂訓練,這部分習題分AB兩個層次,適合不同能力的學生做,做完后收上,課后批改后會了解學生掌握的情況,從而得到準確的學習信息。這部分用時約6分鐘。三)結(jié)課組織學生總結(jié)本節(jié)課。引導(dǎo)學生可對照教學目標總結(jié)知識,從而盡快將知識形成能力;也可總結(jié)方法,從而理解生物學分析思路;還可以談?wù)劯邢?,從而理解人與自然的和諧相處的必要性。最后要求學生完成課后習題,課后時間允許的話還可組織有興趣的同學進行對當?shù)剞r(nóng)田生態(tài)系統(tǒng)的能量流動情況得調(diào)查。這部分用時大約4分鐘。七說板書設(shè)計生態(tài)系統(tǒng)的能量流動一概念:生態(tài)系統(tǒng)中能量的輸入,傳遞和散失過程
(一)教材的地位新中國的成立是20世紀的一件大事。它結(jié)束了幾千年封建專制統(tǒng)治的歷史,開啟了中華民族發(fā)展的新紀元。本課側(cè)重這一時期一個非常顯著的特征,即制度的更新,它本身具有知識的延續(xù)性和鋪墊性。新中國的成立促進了社會經(jīng)濟的發(fā)展,也為祖國的統(tǒng)一奠定了重要基礎(chǔ)。(二)教學目標依據(jù)新課程以人為本,促進學生全面發(fā)展的要求,同時,針對高一年級學生具備一定基礎(chǔ)知識但掌握不牢固,對歷史興趣濃厚但又自制能力差的特點,我對本課的三維目標設(shè)定如下:見多媒體。(三)教學重點的確定及處理本課的主題是新中國的民主政治建設(shè),這個問題的掌握對以后學習中國民主政治建設(shè)的進程有很大幫助,并且學生能力的提高也有賴于對它的認識,所以確定“人民代表大會制度的創(chuàng)立”是教學重點。
強調(diào)重力對生長素分布的影響,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)習舊知識,產(chǎn)生首因效應(yīng),鞏固和加強記憶。通過植物向光性是生長素分布較多而促進生長,進而提出“對于植物來說,生長素是不是越多越好”這個問題,引發(fā)思考,鍛煉思維。說明生長素濃度對不同器官產(chǎn)生的影響不同,讓學生對這一情況有一個整體印象。結(jié)合數(shù)學知識逐步分析圖上各點和各曲線的含義,引導(dǎo)學生得出不同器官對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。通過對曲線的分析,得出低生長素濃度起促進作用,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),對橫放植物“S”型生長進行解釋,達到首尾呼應(yīng)的效果。采用“蒙太奇”手法,引申到“太空中,橫放植物將會如何生長”這個問題,引發(fā)學生的聯(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,掌握了主動權(quán)。
(5)根據(jù)實驗的第五部分——驗證性實驗結(jié)果,證實了達爾文關(guān)于植物向光性運動原因的假說――確實存在一種物質(zhì)致使胚芽尖端產(chǎn)生了向光運動。這樣通過多個實驗的多媒體演示過程,強化學生的思維,最終在學生的大腦中形成科學研究過程的”條件反射”。為了使學生初步學會”設(shè)計對照實驗的方法”,首先也利用多媒體的演示實驗,并在其中特意設(shè)置一些”陷阱”,通過多次”請學生進入‘陷阱’”,來強化設(shè)計實驗時應(yīng)該控制的變量問題,從而在學生的認知領(lǐng)域里初步構(gòu)建出設(shè)計對照實驗的知識體系。3、歸納總結(jié)1934年,荷蘭科學家郭葛等人從植物中分離出了這種能使植物產(chǎn)生向光性的物質(zhì),并確定它就是吲哚乙酸。這就真正從化學物質(zhì)的角度證實了達爾文的假設(shè)。在能夠從植物體中分離提取出生長素之后,要想知道:除了能使植物產(chǎn)生向光運動之外,生長素對于植物的器官還有什么作用?可以采用哪種方法來進行試驗?
4、種群數(shù)量變化的其他類型我結(jié)合“種群數(shù)量下降”這個知識點對學生進行寓教?,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?,F(xiàn)今社會的主題是呼吁建立和諧社會,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,人類只有學會與自然和諧相處,才能在生物圈中享受最大的幸福。6、小結(jié)課程在實驗的大背景下展開,也在實驗的背景中結(jié)束,這里可以呈現(xiàn)出一個完整的探究思路。同時,學生思考如何實現(xiàn)多種預(yù)期過程,相當于對本課進行小結(jié)。五、效果預(yù)測課堂上選取的內(nèi)容基于學生的生活體驗,創(chuàng)設(shè)的情境能激發(fā)學生的興趣,設(shè)置的問題符合學生的認知水平,有助于學生能力的提高,教學目標可以基本實現(xiàn)。
二、君主專制的演進(即中央政治制度的演變)通過地方政治制度演變的學習,掌握方法以后,以學生歸納整理基本線索為主,教師適當點撥,注意糾錯。1. 漢承秦制,又有所變化。教師點撥強調(diào)繼承與發(fā)展兩個方面。創(chuàng)設(shè)情景:同學們看了電視連續(xù)劇《漢武大帝》后,知道漢武帝劉徹在繼位之后,就急于對西漢王朝的政治制度進行改革。那么,西漢初期中央政治制度的基本框架是怎樣的呢?漢武帝為什么要對它進行改革呢?改革后的西漢中央集權(quán)制度又是怎樣的呢?請大家議一議,想一想。主干知識:西漢初期的中央政治制度的最大特點是“漢承秦制”。具體表現(xiàn)在兩個方面:一是繼續(xù)實行皇帝制度,維護皇權(quán),這一做法也為后來各王朝所沿用;二是在中央設(shè)立三公,分別掌管行政、監(jiān)察和軍事。到漢武帝時,“中朝”成為西漢重要的中央決策機構(gòu),尚書令的權(quán)力日益重要,以丞相為首的三公九卿的權(quán)力被削弱,演化為執(zhí)行機構(gòu)。到了東漢光武帝時,進一步剝奪三公權(quán)限,擴大尚書的權(quán)力。
1789年法國大革命后,共和派與君主派之間進行了長期反復(fù)的斗爭,直到1875年法蘭西第三共和國憲法通過才最終確立了共和政體,它為法國資本主義的進一步發(fā)展奠定了基礎(chǔ)。專制色彩濃厚的普魯士通過王朝戰(zhàn)爭這種自上而下的形式,完成了德國的統(tǒng)一。1871年德意志帝國憲法頒布,德國君主立憲政體確立,保留了濃厚的專制殘余和軍國主義傳統(tǒng)。但資產(chǎn)階級代議制的建立使德國的資本主義工業(yè)迅速發(fā)展起來,19世紀末躋身到世界強國行列。資本主義政治制度擴展到了歐洲大陸,隨著這兩個國家資本主義政治制度的確立,近代西方主要資本主義政治制度得以最終確立。四、板書一、法國共和政體確立的艱難歷程1、艱難 (1)表現(xiàn) (2)原因2、確立標志:法蘭西第三共和國憲法
談到這,如果有人會說這僅僅是在于我個人與戰(zhàn)場之上,戰(zhàn)場之下另當別論,那么,他完全錯了。在我小學四年級的語文課上有兩個人發(fā)言積極,一個姓黃,一個姓康,黃同學發(fā)言比康同學更積極,班上的同學常以為黃同學是個了不得的人物,后來,教語文的吳老師曾悄悄地告訴我:班上真正厲害的是康x,那黃x沒什么,說的全是“一點通”上的,照搬不誤。說到這,我還得厚著臉皮自夸一下,在四年級時,我和康同學是同坐,一次,老師叫我們對一片課文(好象是寫黃繼光舍身炸暗堡)的一個段落提問題時,我悄悄地對康同學說了一個問題,康同學對我說:“你站起來說嘛?!眱?nèi)向的我遙遙頭,康同學便站舉手,并起來將我的問題大聲地說了出來,結(jié)果老師說:“恩,康x的問題提得很好?!?/p>
這也就是我在護理崗位上不斷提高,取得一點成績的動力源泉。付出就會有回報,由于平時不懈的努力,在20_年度由甘肅省總工會、共青團甘肅省委、甘肅省人事廳、甘肅省衛(wèi)生廳聯(lián)合舉辦的甘肅省青年崗位技能大賽中奪取了甘肅省青年崗位能手護理技能比賽第一名的佳績,并榮膺了“甘肅省杰出青年崗位能手”殊榮;同時,被省衛(wèi)生廳推薦為全國衛(wèi)生系統(tǒng)護理專業(yè)“巾幗建功”標兵和“全國青年崗位能手”。當然,這些成績的取得,除了我個人的努力之外,離不開我院院領(lǐng)導(dǎo)的支持和鼓勵,離不開同事們的關(guān)心和幫忙,借此機會,向他們表示最衷心的感激!
4,教師重點點撥以下幾個問題⑴廊坊戰(zhàn)役:義和團浴血奮戰(zhàn),對敵人毫不退縮, 其勝利,挫敗了西摩爾聯(lián)軍進犯北京的計劃,沉重打擊了侵略者的氣焰,粉碎了所謂“西方軍隊無敵”的神話。這是對學生進行愛國主義的重要素材之一,教師重點點撥突出其情感教育的重要作用。⑵讓學生(閱讀教材小字和材料,結(jié)合插圖,認清八國聯(lián)軍對中國人民犯下的滔天罪行。)并讓學生分組探討自己的看法,一方面培養(yǎng)學生的語言表訴能力,另一方面通過學生的訴說激發(fā)學生的愛國情感,樹立落后就要挨打的觀念.⑶指導(dǎo)學生通過對條約主要內(nèi)容進行了分析,并自然得出結(jié)論:清政府完全成為帝國主義統(tǒng)治中國的工具,中國完全陷入半殖民地半封建社會。讓學生逐步學會分析和歸納能力(4)進行拓展訓練出示中國近代史上列強的大規(guī)模的侵華戰(zhàn)爭和中國人民的反抗斗爭
The price is the same as(the price was)before the war.價格與戰(zhàn)前相同。(4)定語從句中的“關(guān)系代詞+助動詞be”可以省略。The ticket(that/which was)booked by his sister has been sent to him.他妹妹訂的那張票已送到了他那里。Step 5 PracticeActivity 3(1) Guide students to complete the four activities in the Using Structures part of exercise book, in which activities 1 and 2 focus on ellipsis in dialogue answers, activity 3 focus on signs and headlines, two typical situations where ellipsis is used, and activity 4 focus on ellipsis in diary, an informal style.(2) Combine the examples in the above activities, ask students to summarize the omitted situations in groups, and make their own summary into a poster, and post it on the class wall after class to share with the class.(This step should give full play to the subjectivity of students, and teachers should encourage students to conclude different ellipsis phenomena according to their own understanding, they can conclude according to the different parts omitted in the sentence.)Step 6 Homework1. Understand and master the usages of ellipsis;2. Finish the other exercises in Using structures of Workbook.1、通過本節(jié)內(nèi)容學習,學生是否理解和掌握省略的用法;2、通過本節(jié)內(nèi)容學習,學生能否根據(jù)上下文語境或情景恢復(fù)句子中省略的成分,體會使用省略的效果;3、通過本節(jié)內(nèi)容學習,學生能否獨立完成練習冊和導(dǎo)學案中的相關(guān)練習。
(2)Consolidate key vocabulary.Ask the students to complete the exercises of activity 6 by themselves. Then ask them to check the answers with their partners.(The first language:Damage of the 1906 San Francisco earthquake and fire.A second language: Yunnan - one of the most diverse provinces in China).Step 5 Language points1. The teacher asks the students to read the text carefully, find out the more words and long and difficult sentences in the text and draw lines, understand the use of vocabulary, and analyze the structure of long and difficult sentences.2. The teacher explains and summarizes the usage of core vocabulary and asks the students to take notes.3. The teacher analyzes and explains the long and difficult sentences that the students don't understand, so that the students can understand them better.Step 6 Homework1. Read the text again, in-depth understanding of the text;2. Master the use of core vocabulary and understand the long and difficult sentences.3. Complete relevant exercises in the guide plan.1、通過本節(jié)內(nèi)容學習,學生是否理解和掌握閱讀文本中的新詞匯的意義與用法;2、通過本節(jié)內(nèi)容學習,學生能否結(jié)合文本特點了解文章的結(jié)構(gòu)和作者的寫作邏輯;3、通過本節(jié)內(nèi)容學習,學生能否了解舊金山的城市風貌、文化特色,以及加利福尼亞州的歷史,體會多元文化對美國的影響。
該板塊的活動主題是“介紹一個有顯著文化特征的地方”( Describe a place with distinctive cultural identity)。該板塊通過介紹中國城繼續(xù)聚焦中國文化。本單元主題圖呈現(xiàn)的是舊金山中國城的典型景象, Reading and Thinking部分也提到中國城,為該板塊作鋪墊。介紹中國城的目的主要是體現(xiàn)中國文化與美國多元文化的關(guān)系,它是美國多元文化的重要組成部分。中國城也是海外華人的精神家園和傳播中國文化的重要窗口,外國人在中國城能近距離體驗中國文化。1.

Activity 81.Grasp the main idea of the listening.Listen to the tape and answer the following questions:Who are the two speakers in the listening? What is their relationship?What is the main idea of the first part of the listening? How about the second part?2.Complete the passage.Ask the students to quickly review the summaries of the two listening materials in activity 2. Then play the recording for the second time.Ask them to complete the passage and fill in the blanks.3.Play the recording again and ask the students to use the structure diagram to comb the information structure in the listening.(While listening, take notes. Capture key information quickly and accurately.)Step 8 Talking Activity 91.Focus on the listening text.Listen to the students and listen to the tape. Let them understand the attitudes of Wu Yue and Justin in the conversation.How does Wu Yue feel about Chinese minority cultures?What does Justin think of the Miao and Dong cultures?How do you know that?2.learn functional items that express concerns.Ask students to focus on the expressions listed in activity. 3.And try to analyze the meaning they convey, including praise (Super!).Agree (Exactly!)"(You're kidding.!)Tell me more about it. Tell me more about it.For example, "Yeah Sure." "Definitely!" "Certainly!" "No kidding!" "No wonder!" and so on.4.Ask the students to have conversations in small groups, acting as Jsim and his friends.Justin shares his travels in Guizhou with friends and his thoughts;Justin's friends should give appropriate feedback, express their interest in relevant information, and ask for information when necessary.In order to enrich the dialogue, teachers can expand and supplement the introduction of Miao, dong, Lusheng and Dong Dage.After the group practice, the teacher can choose several groups of students to show, and let the rest of the students listen carefully, after listening to the best performance of the group, and give at least two reasons.
各小組派代表匯報。4、教師提出問題組織學生討論: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要想了解廣大消費者對綠色食品的態(tài)度,食用綠色食品的意義,是否懂得辨認綠色食品,以及什么樣的人群對此知識最缺乏等,我們應(yīng)該怎么做?組織學生匯報交流。5、做個“綠色食品”廣告設(shè)計師。為你喜歡的綠色食品設(shè)計廣告語,每組推薦一個。6、讓學生了解綠色食品認證程序。7、綠色食品打“假”隊員在行動。8、向?qū)W生介紹生態(tài)綠色食品基地。三、活動總結(jié):通過研究、探討,了解學生對綠色食品的態(tài)度。提問:民以食為天,吃,是一個大問題,如果你的爸爸媽媽讓你到超市買牛奶、方便面等,你會選擇什么樣的食品?為什么?希望通過今天的學習,同學們能夠做到綠色消費,也希望你們向自己的家人、向周圍的了解學生對“無公害食品”、“有機食品”與“綠色食品”的認識。
陸王心學與程朱理學相比有何異同?生 不同點:在理的內(nèi)涵上不同,程朱理學認為“理”是貫通于宇宙、人倫的客觀存在,是一種普遍的規(guī)律準則;陸王心學認為心即理,是“良知”,認為人心便是世界萬物的本原。方法上也有不同:前者向外追究,“格物致知”;后者向內(nèi)探求,“發(fā)明本心”以求理,克服私欲、回復(fù)良知。生 相同點:都提出了一個宇宙、社會、人生遵循的“理”。師 對。程朱理學是客觀唯心主義,陽明心學是主觀唯心主義。這兩者的分歧是理學范圍內(nèi)的分歧,其基本思想是一致的。師 宋明理學與漢唐以前的儒學比較,最大的特點在于批判地吸收了佛教哲學的思辨結(jié)構(gòu)和道教的宇宙生成論,將儒家的倫理學說概括升華為哲學基本問題。其實質(zhì)是把佛、道“養(yǎng)性”“修身”引向儒家的“齊家”“治國”“平天下”,對儒家的綱常道德給予哲學論證,使之神圣化、絕對化、普遍化,以便深入人心,做到人人遵而行之。
Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times. The first and listening is extensive listening and the second and third listening is intensive listening. In the first time, They are required to listen a material including Part 1 and Part 2 and choose the best summary of the listening text. After they choose the right answer, They also need work in group to explain what is wrong with the others. Then I will make a conclusion that we should pay attention to the first paragraph and last paragraph and some keys to get the main idea. By doing this, their capacity of generalization will have a great improvement.Before the second listening, I will ask students to scan the blank on the power point quickly and ask them to note down some key words .Then ask them to listen to the Part 1again and fill the first column of the chart. Maybe some students just show the ideas of these three scientists an still can’t catch their development of gravity. Therefore, I will ask them to listen to Part 2 again and fill in the rest. After finish the listening, I will give them ten minutes to discuss with their partner. I will also guidethem to improve their answers when they discuss with others.
Teaching plan for Unit 1 book3Good morning, teachers. It’s my great pleasure to be here because I can share my lesson with you and I can learn a lot from it. I’ll begin my lesson from the following four parts, the teaching material, the teaching methods, the studying methods and the teaching procedure.Firstly, let me talk about the teaching material. The content of my lesson is the reading passage festivals and celebrations of Unit 1 Festivals around the world. This passage is about festivals and celebrations. By studying this passage, we’ll enable the students to know that festivals exit everywhere, and many of festivals in different countries celebrate similar ideas. As we all know, the reading passage is the center of each unit. If the Ss can learn it well, it will be helpful to make the Ss learn the rest of this unit.After studying the teaching material, I think the teaching aims are as the followings:1. Knowledge aims:(1) The Ss can master the usage of the important words andexpressions.(2)The Ss can use the __________________ (grammar) in the proper situation.Make students know about the festivals all over the world and the detail of the festivals, such as origin, content, and the date of the holiday festivals.2. Ability aims:(1) Students can talk about festivals and celebrations in English(2) To improve the student’s reading ability, especially their skimming and scanning ability.3. Emotion aims:Make the Ss know about the foreign festivals, and respect other countries’ custom.Next, let’s come to the important points and the difficult points.The important point is how to make the Ss understand the text better and the difficult point is how can they talk about it. secondly, Teaching Methods:1. task-based Language Teaching2. Computer assisted language teaching.3. question-and–answer methodThirdly, Studying Methods:
在接下來的細讀環(huán)節(jié),我套用了高考對閱讀理解的考查方式設(shè)置了5個問題,分別為三個推理判斷題,一個細節(jié)題和一個主旨大意題。學生需要對文章的內(nèi)容進行分析、歸納、推理、猜測等高級思維活動才能做出正確的回答?!驹O(shè)計意圖】這一過程是對學生進行細讀的訓練,培養(yǎng)學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的關(guān)鍵。首先,讓學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,讓學生仔細閱讀文章,找出可以表現(xiàn)人物態(tài)度變化的具體的語言和動作。最后,讓學生總結(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, 供學生思考?!驹O(shè)計意圖】通過一系列的活動培養(yǎng)學生學習從人物的語言和動作探究人物的心理,使學生進一步體會戲劇語言的魅力,從而對文章背后所反映的社會問題進行思考,也為下一步的討論環(huán)節(jié)做好鋪墊。
在講述細胞分化的意義時,也可以用實例來解決,工廠的生產(chǎn)車間里不同的工人干著不同的工作,一件產(chǎn)品的產(chǎn)出需要這些工人才能創(chuàng)造出來,一個生物體就像一個車間一樣,不同的細胞各司其職,相互合作。工人的分工是主管調(diào)解出來的,而不同細胞的出現(xiàn)就是細胞分化的結(jié)果,所以說,細胞的分化是生物體發(fā)育的基礎(chǔ)。在講到細胞全能性的時候,要多給學生舉些關(guān)于細胞全能性的例子,如植物組織培養(yǎng)、克隆技術(shù)等等,讓學生從實際的例子中真正的悟出細胞全能性的含義。此外,還要重視教材中的疑問,適當對題目進行引申,使它的作用更加突出,有利于學生對知識的串聯(lián)、積累、加工,從而達到舉一反三的效果。怎樣來解釋細胞的全能性呢?這主要以講授法來解釋了,細胞全能性的體現(xiàn)需要在組織或器官離體后才能體現(xiàn)出來,每個細胞都包含著生物體的全套遺傳基因,通過基因選擇性的表達,使離體的組織或器官通過分裂和分化逐漸發(fā)育成完整的植株。
