新課程要求學生知識的獲得由靜態(tài)預設到動態(tài)生成。作為唯物辯證法的一個總特征、用聯(lián)系的觀點看問題是學生遇到的第一個辯證法思想。本教學設計由日常生活中我們所熟知的情境入手引申到聯(lián)系的概念、使學生領悟到成語中蘊藏著豐富的哲理。而后通過分析日常生活中的事例一一講解聯(lián)系的普遍性、客觀性和多樣性、體現(xiàn)出生活處處有哲學的理念,符合學生的認知規(guī)律。在教學過程中、本教學設計安排了必要的學生活動、鍛煉了學生的思維、充分發(fā)揮了學生的主體作用。在這一過程中,知識、情感、態(tài)度、價值觀目標也得到了實現(xiàn)。具體分析如下:第一、這節(jié)課利用多媒體教學方式,把書本與豐富多彩的社會生活聯(lián)系在一起。擴大了學生的眼界和見聞,打破了課堂學習時空的局限,打開了學生思維的心扉,使學生不斷產生濃厚的興趣和探究社會真諦的熱情,并真正成為學習的主人,使學生真正成為教學過程的主體。
培養(yǎng)學生合作交流意識和探究問題的能力,這一部分知識層層遞進,符合學生由特殊到一般、由簡單到復雜的認知規(guī)律。4、互動探究(1)極限思想的滲透讓學生閱讀“思考與討論”小版塊.培養(yǎng)學生的自學和閱讀能力提出下列問題,進行分組討論:a、用課本上的方法估算位移,其結果比實際位移大還是?。繛槭裁??b、為了提高估算的精確度,時間間隔小些好還是大些好?為什么?針對學生回答的多種可能性加以評價和進一步指導。讓學生從討論的結果中歸納得出:△t越小,對位移的估算就越精確。滲透極限的思想。通過小組內分工合作,討論交流,培養(yǎng)學生交流合作的精神,以及搜集信息、處理信息的能力;通過小組間對比總結,使學生學會在對比中發(fā)現(xiàn)問題,在解決問題過程中提高個人能力;
設計意圖:幾道例題及練習題,其中例1小車由靜止啟動開始行駛,以加速度 做勻加速運動,求2s后的速度大???進而變式到:小車遇到紅燈剎車……,充分體現(xiàn)了“從生活到物理,從物理到社會”的物理教學理念;例題及練習題由淺入深、由易到難、各有側重,體現(xiàn)新課標提出的讓不同的學生在物理上得到不同發(fā)展的教學理念。這一環(huán)節(jié)總的設計意圖是反饋教學,內化知識。(6) 小結歸納,拓展深化我的理解是,小結歸納不應該僅僅是知識的簡單羅列,而應該是優(yōu)化認知結構,完善知識體系的一種有效手段,為充分發(fā)揮學生的主題作用,從學習的知識、方法、體驗是那個方面進行歸納,我設計了這么三個問題:① 通過本節(jié)課的學習,你學會了哪些知識;② 通過本節(jié)課的學習,你最大的體驗是什么;③ 通過本節(jié)課的學習,你掌握了哪些學習物理的方法?
一、教材地位《音樂與影視藝術》是人教版高中歷史必修(III)第八專題中的第三節(jié)內容。音樂、影視藝術屬于意識形態(tài)范疇,是當時政治、經(jīng)濟的反映,是社會進步的產物。19世紀以來的音樂與影視藝術糅合了近代科學技術的元素,直接引領著文明發(fā)展趨勢和社會風尚,滿足人們不同層次的審美需要和精神追求。音樂、影視藝術在人類日常生活中無處不在,已經(jīng)成為人們日常生活中的重要組成部分,所以具有重要地位。本課分三個部分介紹了19世紀和20世紀音樂的發(fā)展與變化以及影視藝術的產生發(fā)展。下面我就談談對這節(jié)課的教學思路。二、教材分析1、課標要求課標的要求是:列舉19世紀以來有代表性的音樂作品,理解這些音樂作品的時代性和民族性。了解影視藝術產生與發(fā)展的歷程,認識其對社會生活的影響。2、教學目標根據(jù)新課標、教材內容、學生實際,確定教學目標如下:(1)知識與能力:①列舉19世紀以來有代表性的音樂作品,理解這些音樂作品的時代性和民族性。
人教版新課標教材必修一的“表達交流”部分,有一個專題是“人性的光輝——寫人要凸顯個性”。其中的“寫法借鑒”部分列舉了兩則人物描寫實例,并歸納出人物描寫的幾個要點。其訓練的思路和方法是很明顯的,但所列舉的人物描寫的實例卻不夠典型。而必修一第三單元正好是學習寫人記事散文,其中的兩篇自讀課文《記梁任公先生的一次演講》《金岳霖先生》又是寫人記事非常典型的文章,故而我嘗試將這兩篇文章作為實例和。寫人要凸顯個性。寫作指導結合起來教學。這樣設計還有一個目的,那就是解決課程改革中教學內容多而課時緊張的矛盾,提高課堂教學效率。師:今天,我們一起來學習“寫人要凸顯個性”。這兩堂課分四個步驟來完成:一、先學習教材中關于寫人方法的介紹,約15分鐘;二、快速閱讀第三單元的《記梁任公先生的一次演講》和《金岳霖先生》兩篇文章,具體感受其寫人的方法,約30分鐘;
1.看過了視頻,接下來由各個小組與我們分享他們在課下準備的核心價值觀小品,每組表演時,剩下的小組猜測表演的是哪一個核心價值觀并在活動評價單上進行評分。2.教師總結:“精神文明建設使人們的生活更美好”教師引導學生:精神文明建設搞好了,人心凝聚,精神振奮,各項事業(yè)才會全面興盛。活動二:走進新時代,懷揣中國夢。1.播放“中國夢”優(yōu)秀少兒演講視頻。2.閱讀課本,交流感想?;顒尤籂幾鰰r代好少年1.回顧各小組的表演,把其中所有的不良習慣和閃光舉動逐個挑出來再次強調。2.小組交流班級內部常見的壞習慣。教師總結??偨Y延伸:通過本節(jié)課的學習了解到青少兒應積極投身于社會主義精神文明建設的偉大實踐中去,做新時代的好少,做新時期中國先進文化的傳播者。

The topic of this part is “Discover the reasons for festivals and celebrations.The Listening & Speaking & Talking part aims at talking about the experiences and feelings or emotions about the festivals and celebrations. This section aims at detecting the reason why the people celebrate the festivals, the time, the places, the types and the way of celebrations. It also explains why some traditions in the old celebrations are disappearing, like the firecrackers in the big cities and some new things are appearing like the prosperity of business or commerce. 1. Students can talk about what festivals they know and the reasons and the way of celebrating them.2. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.3. Students can understand the past, the present situation of some festival around the world and why there are some changes about them. 4. Students can have the international awareness about the festivals.1. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.2. Students can understand the past, the present situation of some festival around the world and why there are some changes about them.Step 1 Lead in---Small talkWhat festival do you like best ? Why ?I like the Spring Festivals because I can set off the fireworks, receive the lucky money and enjoy the Gala with my families.Step 2 Before reading---Pair workWhy do people celebrate different festivals ?The Spring Festivals is to celebrate the end of winter and the coming of spring and new life.The Mid-autumn Day is to celebrate the harvest and admire the moon.
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.
2、教學目標根據(jù)我對教材的理解、結合學生的實際情況、滲透新課程的教學理念,為提高全體學生的科學素養(yǎng),按課程標準,以促進全體學生發(fā)展為目的。從知識與技能、過程與方法,情感態(tài)度與價值觀三個方向培養(yǎng)學生,擬定三個教學目標:知識與技能:(1)知道什么是動能。(2)正確理解和運用動能公式分析、解答有關問題。(3)掌握外力對物體所做的總功的計算,理解“代數(shù)和”的含義。(4)理解和運用動能定理。過程與方法:通過演繹推理過程,培養(yǎng)科學研究興趣,領略物理學中所蘊含的嚴謹?shù)倪壿嬯P系。情感、態(tài)度、價值觀:通過運用動能定理分析解決問題,感受成功的喜悅,培養(yǎng)學生對科學研究的興趣。3、教學的重點和難點重點:理解動能定理、應用動能定理解決力學問題。難點:應用動能定理解決多個過程的力學問題,以及變力做功或曲線運動中的動能定理運用。
四.設計反思我在設計本課時,希望通過情境的創(chuàng)設充分再現(xiàn)歷史,并利用多媒體輔助教學,破重點、化難點,讓學生主動參與到學習過程中,從而突破狹小的教室空間,讓學生真正做到感知歷史,立足現(xiàn)實,展望未來。自主,交流、合作、探究是課程改革中著力倡導的新型學習方式。課堂教學中如何開展小組合作的探究學習存在著很多困難,首先是課堂教學時間有限,如何體現(xiàn)面向全體,給每個學生以機會?再次,歷史問題的討論只能依托于史料才能使討論不淪為空談,課堂上通過網(wǎng)絡提供大量的史料(文字、圖片或其他),勢必不能有充分時間讓學生閱讀分析。如何解決這些問題呢?措施一:要形成較固定的歷史學習合作小組。選定一位同學擔任組長,負責協(xié)調措施二:要設置有利于學生探究的問題情境措施三:要把課堂教學與課外學習結合起來。在課前就印發(fā)相關的材料,或引導學生去查閱相關的資料,讓學生有個充分的閱讀、思考、交流的時間,是保證課堂上小組交流能成功實現(xiàn)的一個前提
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. Use this checklist to help your partner revise his/her draft.1.Does the writer explain why he/she changed/wanted to change?2.Does the writer tell how the changes have improved or will improve his/her life?3.Is the text well-organised?4.Does the writer use words and expressions to show similarities and differences?5.Are there any grammar or spelling errors?6.Does the writer use correct punctuation?
The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut
The theme of this unit focuses on “space exploration.” Students will learn about the training and experience needed to become an astronaut. The text is mainly about the development of space exploration. On the one hand, the text helps students to have a good understanding about the great feats humans have achieved, on the other hand, they will further understand the contributions that we Chinese have achieved, and feel confident and proud about our homeland and strengthen their love for our country. The teacher should instruct students to aim high and study harder to make great progress in the space career if possible.1. Read about the development and value of space exploration.2. Explore the mysteries of the universe and the achievements in space exploration.3. Skillfully use the vocabulary of this text to cultivate self-study ability 4. Develop cooperative learning ability through discussion.1. Enable the Ss to talk about the development and value of space exploration.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.3. Help Ss comprehend the main reasons for space exploration. Multi-media, textbook, notebooks.Step 1: Warming up and predictionLook at the title and the pictures of the text and predict what the text will be about?2. What are the main reasons for space exploration?

導語在必修第一冊中,我們研究了函數(shù)的單調性,并利用函數(shù)單調性等知識,定性的研究了一次函數(shù)、指數(shù)函數(shù)、對數(shù)函數(shù)增長速度的差異,知道“對數(shù)增長” 是越來越慢的,“指數(shù)爆炸” 比“直線上升” 快得多,進一步的能否精確定量的刻畫變化速度的快慢呢,下面我們就來研究這個問題。新知探究問題1 高臺跳水運動員的速度高臺跳水運動中,運動員在運動過程中的重心相對于水面的高度h(單位:m)與起跳后的時間t(單位:s)存在函數(shù)關系h(t)=-4.9t2+4.8t+11.如何描述用運動員從起跳到入水的過程中運動的快慢程度呢?直覺告訴我們,運動員從起跳到入水的過程中,在上升階段運動的越來越慢,在下降階段運動的越來越快,我們可以把整個運動時間段分成許多小段,用運動員在每段時間內的平均速度v ?近似的描述它的運動狀態(tài)。
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(5)。從新詞新語的產生途徑可以看出,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,以及人們日常生活的各個層面如人生意義、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。
(2)多媒體展示:消費者們反映iPhone4的500萬像素太不給力,3,5英寸的屏幕太小,促使蘋果公司給新一代iPhone裝上了一顆800萬像素的攝像頭4,0英寸的屏幕等,發(fā)展到最新的一代iPhone6plus已經(jīng)達到5.5英寸。師:新一代iphone更新的驅動力是什么呢?其實新產品的升級對于蘋果公司來說經(jīng)費投入不小但是不經(jīng)過升級換代產品就不能滿足消費者的新的消費要求,所以消費者的反應客觀上促進了iphone的升級換代——消費對生產的調整與升級起著導向作用(3)多媒體展示:隨著網(wǎng)購迅猛的發(fā)展,快遞、倉儲業(yè)務等也出現(xiàn)爆發(fā)式增長。這一現(xiàn)象說明了什么?(舉例:iPhone在全球市場的火熱,“殼”文化產業(yè)第一個進入人們的視線,隨著時間的發(fā)展,外殼的產業(yè)飛速蓬勃的發(fā)展著)結論:一個新的消費熱點的出現(xiàn)往往能帶動一個或多個產業(yè)的出現(xiàn)和成長。消費所形成的新的需求對生產的調整和升級起著導向作用,需求的數(shù)量和質量調節(jié)供給的數(shù)量和質量。
