人教版高中政治必修3在文化生活中選擇說課稿
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(xué)情分析高二學(xué)生處于世界觀、人生觀和價(jià)值觀形成的關(guān)鍵時(shí)期，身心迅速發(fā)展，自我意識和獨(dú)立性較強(qiáng)，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(qiáng)，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(qiáng)方法論的指導(dǎo)，使其在紛繁復(fù)雜的文化生活中能夠進(jìn)行正確的判斷與選擇。如果我們的學(xué)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。

2．講授新課：（約35分鐘）結(jié)合教材內(nèi)容重難點(diǎn)和學(xué)生實(shí)際，在講課過程中，我對教材內(nèi)容的順序進(jìn)行了重組，把教材內(nèi)容由原來的兩大部分劃分為三大部分（第一，價(jià)值判斷和價(jià)值選擇的含義和關(guān)系；第二，價(jià)值判斷和價(jià)值選擇的特征；第三，做出正確的價(jià)值判斷和價(jià)值選擇的標(biāo)準(zhǔn)）。這一調(diào)整更符合學(xué)生的認(rèn)知結(jié)構(gòu)，便于從整體上把握課本內(nèi)容。在講授過程中，我充分利用課本素材——探究活動為課堂教學(xué)服務(wù)，此外，利用學(xué)生的生活與體驗(yàn)，挖掘?qū)嵗?，如結(jié)婚要禮由以前的舊三件到現(xiàn)如今的轉(zhuǎn)變，引導(dǎo)學(xué)生理解價(jià)值判斷和價(jià)值選擇的社會歷史性特征，以以《觀祈雨》、以醫(yī)生、藝術(shù)家、老學(xué)究對于《斷臂的維納斯》這個(gè)雕塑的不同見解、以新鮮實(shí)例韓國沉船事件和范跑跑為例啟發(fā)學(xué)生價(jià)值判斷和價(jià)值選擇具有主體差異性特征以此突破難點(diǎn)，最后通過設(shè)疑、對比、追問正確的價(jià)值判斷和價(jià)值選擇的標(biāo)準(zhǔn)來深化主題，突出重點(diǎn)。3．課堂小結(jié)：（約2分鐘）強(qiáng)化認(rèn)識

（7）精講即精講點(diǎn)撥，釋疑解難?，F(xiàn)代教育理論一方面強(qiáng)調(diào)學(xué)生學(xué)習(xí)的主動性；另一方面也重視發(fā)揮教師的積極性。課堂活動的主動性、合理性、有效性的實(shí)現(xiàn)還有賴于教師的講。精講就要求教師的講授內(nèi)容精要，分析精辟，語言精彩、節(jié)奏精練、點(diǎn)撥精當(dāng)。從內(nèi)容上看，本節(jié)課精講主要有三處：一、運(yùn)動的含義；二、運(yùn)動是物質(zhì)的根本屬性；三、靜止是運(yùn)動的特殊狀態(tài)。2、教學(xué)手段多媒體輔助教學(xué)。六、教學(xué)過程第一步：創(chuàng)設(shè)情景，用“謎語”導(dǎo)入新課。使學(xué)生置身于教學(xué)內(nèi)容的情景之中，產(chǎn)生繼續(xù)探究的強(qiáng)烈愿望。第二步：運(yùn)用直觀、形象的畫面將教學(xué)目標(biāo)問題，喚起學(xué)生參與欲望，驅(qū)使學(xué)生去思考，去自讀。第三步：引導(dǎo)學(xué)生相互討論，實(shí)現(xiàn)學(xué)生之間的橫向交流。第四步：教師依據(jù)反饋信息，給予重點(diǎn)講授、提示點(diǎn)撥、搭橋鋪路。第五步：設(shè)置故事型的模擬法庭，開展討論，在高潮中結(jié)束新課。第六步：總結(jié)概括，深化知識，形成網(wǎng)絡(luò)。

2、講授新課：在講授新課的過程中，我突出教材的重點(diǎn)，明了地分析教材的難點(diǎn)。還根據(jù)教材的特點(diǎn)，學(xué)生的實(shí)際、教師的特長，以及教學(xué)設(shè)備的情況，我選擇了多媒體的教學(xué)手段。這些教學(xué)手段的運(yùn)用可以使抽象的知識具體化，枯燥的知識生動化，乏味的知識興趣化。還重視教材中的疑問，適當(dāng)對題目進(jìn)行引申,使它的作用更加突出，有利于學(xué)生對知識的串聯(lián)、積累、加工，從而達(dá)到舉一反三的效果。3、課堂小結(jié)，強(qiáng)化認(rèn)識：課堂小結(jié)，可以把課堂傳授的知識盡快地轉(zhuǎn)化為學(xué)生的素質(zhì)；簡單扼要的課堂小結(jié)，可使學(xué)生更深刻地理解政治理論在實(shí)際生活中的應(yīng)用，并且逐漸地培養(yǎng)學(xué)生具有良好的個(gè)性。4、板書設(shè)計(jì)我比較注重直觀、系統(tǒng)的板書設(shè)計(jì)，還及時(shí)地體現(xiàn)教材中的知識點(diǎn)，以便于學(xué)生能夠理解掌握。

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.

Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …h(huán)orse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角）left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything.

了解了第一宇宙速度及其意義之后，繼續(xù)提出問題，讓學(xué)生思考：如果衛(wèi)星的發(fā)射速度大于第一宇宙速度7.9km/s ，會出現(xiàn)什么情況呢？先讓學(xué)生們大膽猜想，然后再向?qū)W生們介紹 衛(wèi)星發(fā)射速度大于第一宇宙速度后的幾種可能情況，引出第二宇宙速度和第三宇宙速度，讓學(xué)生對第二、第三宇宙速度及其意義做定性了解。并通過演示Flash課件，幫助學(xué)生理解、加深學(xué)生印象。在學(xué)生對人造衛(wèi)星的原理及發(fā)射衛(wèi)星的速度條件有了初步了解后，接下來引導(dǎo)學(xué)生對衛(wèi)星的運(yùn)動規(guī)律作進(jìn)一步的探索。實(shí)際上衛(wèi)星并不是沿地表水平發(fā)射的，而是用火箭多次加速送到一定的高度的軌道后，再沿以地心為圓心的圓周的切線運(yùn)行的。讓學(xué)生繼續(xù)深入思考：衛(wèi)星在不同高度繞地球運(yùn)行時(shí)的速度怎么求呢？將衛(wèi)星送入低軌道和高軌道所需的速度都一樣么？如果把不同軌道上的衛(wèi)星繞地球的運(yùn)動都看成是勻速圓周運(yùn)動，引導(dǎo)學(xué)生利用已學(xué)的萬有引力和圓周運(yùn)動的相關(guān)知識，探究衛(wèi)星繞地球的運(yùn)行規(guī)律。
