人教版高中政治必修3傳統(tǒng)文化的繼承教案
思考：在我們今天的生活中，應該如何認識“孝”道？（“孝”為中華民族傳統(tǒng)道德之本。在封建社會，“孝”被異化為封建統(tǒng)治階級統(tǒng)治人民、維系政權的一個最重要的工具；一切聽命于“一家之長”的觀念，使人們往往屈從于獨斷的權威或傳統(tǒng)的家庭禮教，失去了獨立的人格。另一方面，“孝”從它本身意義出發(fā)，所包含的尊老、敬老、養(yǎng)老，以及親親、愛人、愛國，正是中華民族的一大傳統(tǒng)美德，是中華民族家庭和睦、鄰里相親、社會穩(wěn)定的重要內在因素。因此，孝道已被列為中華傳統(tǒng)道德教育的重要內容。）所以我們要辯證地認識傳統(tǒng)文化在現(xiàn)實生活中的作用，做到“取其精華，去其糟粕；批判繼承，古為今用”。對于傳統(tǒng)文化中符合社會發(fā)展要求的、積極的、向上的內容，應該繼續(xù)保持和發(fā)揚。對于傳統(tǒng)文化中不符合社會發(fā)展要求的、落后的、腐朽的東西，必須“移風易俗”，自覺地加以改造或剔除。2、正確對待傳統(tǒng)文化的意義
人教版高中政治必修3世界文化的多樣性教案
五、課后反思課后組織學生討論對本課的感受，同學們都非常樂意采取這種上課方式，既可以通過資料的搜集、整理提高自身信息采集的能力，也能夠提高自己學習積極性，變枯燥為生動。本人在教學中也深深地感到：一方面，充分發(fā)揮學生的主體作用，有利于啟發(fā)同學的思維，培養(yǎng)自主思考的能力。而充分利用網(wǎng)絡的教學功能，將現(xiàn)代信息技術和學科教學很好地結合了起來。只有調動全體同學的積極性、主動性、創(chuàng)造性，我們的教學才能有生命力；另一方面，光有學生的活動也不行，雖然學生能夠積極投入地利用互聯(lián)網(wǎng)搜集并動手制作課件，在課堂交流中能很好地進行發(fā)散思維和創(chuàng)造性思維，但其集中思維和抽象性思維還存在一定的缺陷，主要體現(xiàn)在對搜集的材料的取舍是以及對知識點的歸納和深化方面，所以在充分發(fā)揮學生的主體作用的同時應該也必須重視教師主導作用的發(fā)揮，引導學生由形象到抽象、由發(fā)散到集中、由演繹到歸納的思維能力的逐步提高。

人教版高中政治必修1新時代的勞動者教案
總之，依法維護勞動者合法權益，是保障勞動者主人翁地位的前提，是充分調動勞動者積極性、創(chuàng)造性，使之成為改革開放和社會主義建設主力軍的保證。也是促進勞動力資源合理配置，促進經濟持續(xù)、快速、健康發(fā)展的需要。（三）課堂總結、點評★課余作業(yè)某企業(yè)由于生產任務較大，在未經勞動行政部門批準的情況下，廠長強行讓部分職工延長勞動時間，每天加時工作，星期天也照常上班，不讓休息。到月底，部分職工全月累計加班加點高達120小時，也不發(fā)加班工資。根據(jù)上述材料回答：你認為該廠的做法是否合法？為什么？勞動者依法享有哪些權利？該廠的做法侵害了勞動者的哪些權利？這些工人應當怎么辦？★教學體會本節(jié)學習勞動者的權利和樹立什么樣的就業(yè)觀等問題，與大家的生活聯(lián)系比較密切。因此，在講解過程中要通過大量的實例和對比，引導學生思考和討論，將市場經濟中的一些理論知識潛移默化的給學生。
人教版新課標高中物理必修2平拋運動教案2篇
（五）平拋運動規(guī)律的應用例1：一架老式飛機在高出海面45m的高處，以80m/s的速度水平飛行，為了使飛機上投下的炸彈落在停在海面上的敵船，應該在與轟炸目標的水平距離為多遠的地方投彈?不計空氣阻力。分析：對于這道題我們可以從以下幾個方面來考慮：(1)從水平飛行的飛機上投下的炸彈，做什么運動?為什么?(2)炸彈的這種運動可分解為哪兩個什么樣的分運動?3)要想使炸彈投到指定的目標處，你認為炸彈落地前在水平方向通過的距離與投彈時飛機離目標的水平距離之間有什么關系?拓展：1、式飛機在高出海面45m的高處，以80m/s的速度水平飛行，尾追一艘以15m/s逃逸的敵船，為了使飛機上投下的炸彈正好擊中敵船，應該在與轟炸目標的水平距離為多遠的地方投彈?不計空氣阻力。2、在一次摩托車跨越壕溝的表演中，摩托車從壕溝的一側以速度v＝40m/s沿水平方向向另一側，壕溝兩側的高度及寬度如圖所示，摩托車可看做質點，不計空氣阻力。（1）判斷摩托車能否跨越壕溝？請計算說明（2）若能跨過，求落地速度？
人教版新課標高中物理必修2功率教案2篇
1．用CAI課件模擬汽車的啟動過程。師生共同討論：①如果作用在物體上的力為恒力，且物體以勻速運動，則力對物體做功的功率保持不變。此情況下，任意一段時間內的平均功率與任一瞬時的瞬時功率都是相同的。②很多動力機器通常有一個額定功率，且通常使其在額定功率狀態(tài)工作（如汽車），根據(jù)P=FV可知：當路面阻力較小時，牽引力也小，速度大，即汽車可以跑得快些；當路面阻力較大，或爬坡時，需要比較大的牽引力，速度必須小。這就是爬坡時汽車換低速擋的道理。③如果動力機器在實際功率小于額定功率的條件下工作，例如汽車剛剛起動后的一段時間內，速度逐漸增大過程中，牽引力仍可增大，即F和v可以同時增大，但是這一情況應以二者乘積等于額定功率為限度，即當實際功率大于額定功率以后，這種情況不可能實現(xiàn)。

新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學設計
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.
