一、教材分析行星的運動選自人教版普通高中物理必修2第六章第1節(jié)。本節(jié)教學(xué)既是前面《運動的描述》和《曲線運動》內(nèi)容的進(jìn)一步的延伸和拓展,又能為后面學(xué)習(xí)萬有引力定律做鋪墊。在本章中占有較為重要的地位,具有承前啟后的作用。同時該節(jié)內(nèi)容也涉及大量物理史實、貼近學(xué)生生活和聯(lián)系社會實際的事實,可進(jìn)一步培育學(xué)生的科學(xué)情感、精神和發(fā)展觀。(一)教學(xué)目標(biāo) 1.知識與技能(1)知道地心說和日心說的基本內(nèi)容。(2.)掌握理解開普勒三大定律的內(nèi)容,并能應(yīng)用。(3)理解人們對行星運動的認(rèn)識過程是漫長復(fù)雜的,真理是來之不易的。2.過程與方法通過托勒密、哥白尼、第谷·布拉赫、開普勒等幾位科學(xué)家對行星運動的不同認(rèn)識,了解人類認(rèn)識事物本質(zhì)的曲折性并加深對行星運動的理解。3.情感、態(tài)度與價值觀(1)澄清對天體運動神秘、模糊的認(rèn)識,掌握人類認(rèn)識自然規(guī)律的科學(xué)方法。(2)感悟科學(xué)是人類進(jìn)步不竭的動力。

一、教材分析(一)說本框題的地位與作用《樹立創(chuàng)新意識是唯物辯證法的要求》是人教版教材高二《生活與哲學(xué)》第三單元第十課的第一框題,該部分的內(nèi)容實質(zhì)上是在闡述辯證法的革命批判精神和否定之否定規(guī)律。是第三單元思想方法與創(chuàng)新意識》的重點和核心之一。學(xué)好這部分的知識對于學(xué)生進(jìn)一步理解辯證法的思維方法,樹立創(chuàng)新意識起著重要的作用。(二)說教學(xué)目標(biāo)根據(jù)課程標(biāo)準(zhǔn)和課改精神,在教學(xué)中確定如下三維目標(biāo):1、知識目標(biāo):辯證否定觀的內(nèi)涵,辯證法的本質(zhì)。辯證否定是自我否定,辯證否定觀與書本知識和權(quán)威思想的關(guān)系,辯證法的革命批判精神與創(chuàng)新意識的關(guān)系,分析辯證否定的實質(zhì)是"揚棄",是既肯定又否定;既克服又保留。深刻理解辯證法的革命批判精神,分析為什么辯證法的革命批判精神同創(chuàng)新意識息息相關(guān)。

本節(jié)課標(biāo)解讀:1.說明以種植業(yè)為主的農(nóng)業(yè)地域類型的形成條件及特點;2.說出商品谷物農(nóng)業(yè)的分布范圍,說明商品谷物農(nóng)業(yè)的形成條件及特點。內(nèi)容地位與作用:農(nóng)業(yè)是受自然環(huán)境影響最大的產(chǎn)業(yè)。農(nóng)業(yè)是發(fā)展歷史最悠久的產(chǎn)業(yè),隨著社會的發(fā)展和進(jìn)步,社會環(huán)境對農(nóng)業(yè)的影響越來越大。以季風(fēng)水田農(nóng)業(yè)為主的農(nóng)業(yè)地域類型,主要體現(xiàn)自然環(huán)境對農(nóng)業(yè)地域形成的影響;商品谷物農(nóng)業(yè)則體現(xiàn)了社會環(huán)境對農(nóng)業(yè)地域形成的影響。本節(jié)內(nèi)容包括兩部分內(nèi)容,一個是季風(fēng)水田農(nóng)業(yè),主要分布在亞洲季風(fēng)區(qū);一個是商品谷物農(nóng)業(yè),主要分布在發(fā)達(dá)國家。教材文字內(nèi)容不多,配備了大量的地圖和景觀圖。因此,在教學(xué)過程中要充分組織學(xué)生查閱地圖,挖掘地理信息,培養(yǎng)分析能力。分析農(nóng)業(yè)區(qū)位因素時,必須從自然因素和社會經(jīng)濟因素兩個方面去分析,找出優(yōu)勢區(qū)位因素來。

培養(yǎng)學(xué)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(jìn),符合學(xué)生由特殊到一般、由簡單到復(fù)雜的認(rèn)知規(guī)律。4、互動探究(1)極限思想的滲透讓學(xué)生閱讀“思考與討論”小版塊.培養(yǎng)學(xué)生的自學(xué)和閱讀能力提出下列問題,進(jìn)行分組討論:a、用課本上的方法估算位移,其結(jié)果比實際位移大還是小?為什么?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(xué)生回答的多種可能性加以評價和進(jìn)一步指導(dǎo)。讓學(xué)生從討論的結(jié)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(nèi)分工合作,討論交流,培養(yǎng)學(xué)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(jié),使學(xué)生學(xué)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(shè)計意圖:幾道例題及練習(xí)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(jìn)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(xué)理念;例題及練習(xí)題由淺入深、由易到難、各有側(cè)重,體現(xiàn)新課標(biāo)提出的讓不同的學(xué)生在物理上得到不同發(fā)展的教學(xué)理念。這一環(huán)節(jié)總的設(shè)計意圖是反饋教學(xué),內(nèi)化知識。(6) 小結(jié)歸納,拓展深化我的理解是,小結(jié)歸納不應(yīng)該僅僅是知識的簡單羅列,而應(yīng)該是優(yōu)化認(rèn)知結(jié)構(gòu),完善知識體系的一種有效手段,為充分發(fā)揮學(xué)生的主題作用,從學(xué)習(xí)的知識、方法、體驗是那個方面進(jìn)行歸納,我設(shè)計了這么三個問題:① 通過本節(jié)課的學(xué)習(xí),你學(xué)會了哪些知識;② 通過本節(jié)課的學(xué)習(xí),你最大的體驗是什么;③ 通過本節(jié)課的學(xué)習(xí),你掌握了哪些學(xué)習(xí)物理的方法?

1.聚焦課堂,服務(wù)教學(xué)。積極圍繞“優(yōu)質(zhì)高效的課堂教學(xué)” 開展教學(xué)調(diào)研、課改實踐、教學(xué)研訓(xùn)、質(zhì)量監(jiān)控等教研活動,努力提高課堂教學(xué)效率?! ?、以教師專業(yè)發(fā)展為中心,積極開展教學(xué)研究、教學(xué)指導(dǎo)和教學(xué)服務(wù)工作,努力提高教師專業(yè)發(fā)展水平。 3、以龍崗教研網(wǎng)為平臺,做好資源整合工作,嘗試開展網(wǎng)絡(luò)教研教學(xué)活動,提高教研實效。

二、教學(xué)設(shè)想1、研究考試大綱,加強學(xué)習(xí)。2、狠抓專項復(fù)習(xí),夯實基礎(chǔ)。3、落實培優(yōu)補差工作,分層教學(xué)。4、落實問題教學(xué),提高教學(xué)效率。

二、說學(xué)情學(xué)生狀況:當(dāng)代中學(xué)生在科學(xué)不斷進(jìn)步,文化不斷發(fā)展,社會不斷變革的今天,雖然能很快適應(yīng)現(xiàn)代社會生活,但他們的心理還不夠成熟,在情緒特征上表現(xiàn)為好沖動、不穩(wěn)定、極端化等特點。對自己的不良情緒表現(xiàn)缺乏深刻地認(rèn)識,也不善于調(diào)適自己的情緒。而且高一學(xué)生正處于人生的重要關(guān)口,已經(jīng)有較強的獨立意識,但是自控能力和心理調(diào)節(jié)能力還比較薄弱,又處于發(fā)展的不完全成熟時期,形成了他們內(nèi)心需要與意志調(diào)控能力之間的失調(diào),從而導(dǎo)致他們在處理很多學(xué)習(xí)和生活中的問題時沖動、極端化,難以很好的調(diào)適自己的情緒。

本節(jié)課選自《普通高中課程標(biāo)準(zhǔn)實驗教科書數(shù)學(xué)必修1》5.6.2節(jié) 函數(shù)y=Asin(ωx+φ)的圖象通過圖象變換,揭示參數(shù)φ、ω、A變化時對函數(shù)圖象的形狀和位置的影響。通過引導(dǎo)學(xué)生對函數(shù)y=sinx到y(tǒng)=Asin(ωx+φ)的圖象變換規(guī)律的探索,讓學(xué)生體會到由簡單到復(fù)雜、由特殊到一般的化歸思想;并通過對周期變換、相位變換先后順序調(diào)整后,將影響圖象變換這一難點的突破,讓學(xué)生學(xué)會抓住問題的主要矛盾來解決問題的基本思想方法;通過對參數(shù)φ、ω、A的分類討論,讓學(xué)生深刻認(rèn)識圖象變換與函數(shù)解析式變換的內(nèi)在聯(lián)系。通過圖象變換和“五點”作圖法,正確找出函數(shù)y=sinx到y(tǒng)=Asin(ωx+φ)的圖象變換規(guī)律,這也是本節(jié)課的重點所在。提高學(xué)生的推理能力。讓學(xué)生感受數(shù)形結(jié)合及轉(zhuǎn)化的思想方法。發(fā)展學(xué)生數(shù)學(xué)直觀、數(shù)學(xué)抽象、邏輯推理、數(shù)學(xué)建模的核心素養(yǎng)。

1、舉例:2、結(jié)論:(1)物體的運動軌跡是曲線的運動叫曲線運動。(2)曲線運動中速度方向是時刻改變的。(二)、曲線運動方向:1、質(zhì)點在某一點(或某一時刻)的速度的方向是在曲線的這一點的切線方向。2、曲線運動中速度方向是時刻改變的,因此曲線運動是變速運動。(三)、曲線運動條件:1、演示實驗:2、結(jié)論:當(dāng)物體所受的合力的方向跟它的速度方向不在同一直線時,物體就做曲線運動。七、課堂小結(jié):1、運動軌跡是曲線的運動叫曲線運動。2、曲線運動中速度的方向是時刻改變的,質(zhì)點在某一點的瞬時速度的方向在曲線的這一點的切線上。3、當(dāng)合外力F的方向與它的速度方向有一夾角a時,物體做曲線運動。八、鞏固訓(xùn)練:1、關(guān)于曲線運動,下列說法正確的是()。A:曲線運動一定是變速運動;B:曲線運動速度的方向不斷的變化,但速度的大小可以不變;

【課堂小結(jié)】本課主要講述俄國十月革命后進(jìn)行經(jīng)濟建設(shè),并在建設(shè)中進(jìn)行社會主義探索,期間先后出現(xiàn)了戰(zhàn)時共產(chǎn)主義政策、新經(jīng)濟政策和斯大林模式,這些政策和體制的產(chǎn)生都是歷史和當(dāng)時現(xiàn)實有關(guān),但也反映出在建設(shè)社會主義中既有成功的也由重大失誤,主要在于缺乏現(xiàn)成的政策和模式可供借鑒,更在于理論上的缺乏。斯大林模式的形成同蘇聯(lián)當(dāng)時社會生產(chǎn)力的發(fā)展水平相適應(yīng),它在初期和戰(zhàn)爭時期曾發(fā)揮了巨大作用,使蘇聯(lián)成為強大的社會主義國家。它建立的高度集中的計劃經(jīng)濟體制和新型的工業(yè)化模式是蘇聯(lián)進(jìn)行社會主義建設(shè)中的探索和創(chuàng)新,對二戰(zhàn)后社會主義國家產(chǎn)生了深刻影響,促進(jìn)這些國家國民經(jīng)濟的恢復(fù)和發(fā)展,形成了足以同資本主義相抗衡的社會主義陣營。但是,它沒有解決社會主義民主政治建設(shè)和經(jīng)濟運行的一系列根本問題,違背了列寧關(guān)于把文化經(jīng)濟建設(shè)當(dāng)作工作重心的指示,仍把政治斗爭放在第一位。

由此引導(dǎo)學(xué)生的深思,學(xué)生通過合作探究,幫助學(xué)生認(rèn)識到不注重思想道德修養(yǎng),即使掌握了豐富的科學(xué)知識,也難以避免人格上的缺失,甚至危害社會。進(jìn)而總結(jié)出關(guān)系二:加強思想道德修養(yǎng),能夠促進(jìn)科學(xué)文化修養(yǎng)??茖W(xué)文化修養(yǎng)的意義播放感動中國人物徐本禹先進(jìn)事跡短片。學(xué)生觀看完視頻后,思考:從徐本禹的事跡中,我們可以了解到我們加強科學(xué)文化修養(yǎng)的根本意義是什么?引導(dǎo)學(xué)生結(jié)合自身體會,發(fā)表各自見解,在此基礎(chǔ)上幫助學(xué)生總結(jié)出,要使自己的思想道德境界不斷升華,為人民服務(wù)的本領(lǐng)不斷提高,成為一個真正有知識文化涵養(yǎng)的人,成為一個脫離低級趣味的人、有益于人民的人。知識點三:追求更高的思想道德目標(biāo)根據(jù)教材110探究活動(思想道德的差異、反應(yīng)人們世界觀、人生觀、價值觀的差異)思考:用公民的基本道德規(guī)范來衡量這些觀點,你贊成哪些觀點?反對哪些觀點?小組進(jìn)行合作探究,引導(dǎo)學(xué)生根據(jù)公民基本道德規(guī)范對這些價值觀進(jìn)行評析。

(3)改造主觀世界同改造客觀世界的關(guān)系。改造客觀世界同改造主觀世界,是相互聯(lián)系、相互作用的。改造主觀世界是為了更好地改造客觀世界,人們在改造客觀世界的同時也改造著自己的主觀世界。通過自覺改造主觀世界,又能提高改造客觀世界的能力。師:人們對自己的思想道德境界的追求,是永遠(yuǎn)止境的。讓我們共同努力,在踐行社會主義思想道德的過程中,不斷追求更高的目標(biāo),像無數(shù)先輩那樣,加入到為共產(chǎn)主義遠(yuǎn)大理想而奮斗的行列中吧!課堂小結(jié)通過本節(jié)課學(xué)習(xí)使我們認(rèn)識到面對現(xiàn)實生活中的思想道德沖突,加強知識文化修養(yǎng)和思想道德修養(yǎng),不斷追求更高的思想道德目標(biāo)的必要性;把握了知識文化修養(yǎng)與思想道德修養(yǎng)的含義及其相互關(guān)系;明確了我們應(yīng)該和怎樣追求更高的思想道德目標(biāo);認(rèn)識到這是一個永無止境的過程。我們要腳踏實地,從現(xiàn)在做起、從點滴小事做起,不斷提高知識文化修養(yǎng)和思想道德修養(yǎng),追求更高的思想道德目標(biāo)。

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.

The topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate. Students not only learn the festival, but touch and feel the Inner Mongolian’s character, the spirit and cultural atmosphere, which can help students form the cultural awareness and learn to enjoy and value the diversity of Chinese culture.Concretely, the dairy tells the experience that the author spent the Naadam Festival in Inner Mongolia Autonomous Region with his/her friend. The structure is clear. In the opening paragraph, it introduces the topic of the Naadam Festival and the whole feeling. Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1. Read quickly to get main idea; read carefully to get the detailed information about Naadam Festival.2. Learn the structure of the reading article and language.3. Write an article about a festival experience4. Learn to use the psychology, emotions and feeling in the writing.1. Write an article about a festival experience.2. Use the structure of the reading article and language.

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 topic of this part is “Learn to make choices in life”.The Listening & Speaking & Talking part aims at the moral dilemmas, and this part is about making choices in life. The heroin is Lin Qiaozhi, a famous medical scientist, made a great contribution to our country’s medical care. Most importantly, her life experience can inspire our students whether in studying or the development of career. she had moral dilemmas and life choices, which are similar to the students who will step into society. Besides, Lin has quite good virtues like kindness, self-improvement, insistence, job-loving , generosity and responsibility, which is worth being learned.Concretely, this article is a biography about Lin Qiaozhi. The article tells her whole life according the timeline, among which the life choices is emphasized. For example, whether married or chased her dream, returned home or stayed abroad, family or public, her choices all reflected her faith, spirit, responsibility and devotion.1. Fast reading to get the detailed information about Lin Qiaozhi; careful reading to do the deductive information.2. Learn the reading skills--deductive judgement according the context.3. Study the structure features and language features. 4. Communicate about Lin’s life choices and reflect their own life choices.1. Learn the reading skills--deductive judgement according the context.2. Study the structure features and language features.3.
