二、說學情本課的教學對象為高二學生，他們思維活躍已具備一定歸納能力和分析、綜合能力，能夠自主地分析現(xiàn)實生活中的一些文化行為，但看問題往往比較偏激、片面，缺乏良好的邏輯思維能力。所以，在文化創(chuàng)新的途徑上要對他們進行指導，以免走入誤區(qū)。三、教學目標根據(jù)新課程標準、教材特點、學生的實際，我確定了如下教學目標：【知識與能力目標】1.理解文化創(chuàng)新的根本途徑和兩個基本途徑;2.了解文化創(chuàng)新過程中需要堅持正確方向，克服錯誤傾向。

1842年鴉片戰(zhàn)爭清政府戰(zhàn)敗，簽訂《南京條約》，以英國為首的外國資本主義開始入侵，五口通商，協(xié)議關稅，西方商品輸入與日俱增，機器化大生產速度快，用政治經濟學的觀點就是社會必要勞動時間少，成本低，價格更加便宜，所謂物美價廉，市場競爭力強，材料：1845年，福州官員奏稱：洋貨“充積于廈口”。洋布、洋棉“其質既美、其價復廉，民間之買洋布、洋棉者，十室而九。”因此，“江浙之棉布不復暢銷”。生：洋貨的輸入，土布土紗的銷售陷入困境，賣不出去，依靠它生活的手工業(yè)者就活不下去了，一部分棉紡織業(yè)手工者破產失業(yè)，為了維持生計，流入城市工廠，替別人打工，成為自由勞動力；以前吃穿自己生產，現(xiàn)在吃穿要買，于是這部分手工業(yè)者從生產者變成了消費者，有了消費就有了市場。

【合作探索】經濟全球化和經濟區(qū)域集團化的關系？相互促進，相互制約。促進：經濟全球化不平衡導致經濟區(qū)域集團化，區(qū)域集團化是經濟全球化的具體表現(xiàn)，經濟區(qū)域集團化是最終實現(xiàn)經濟全球化的重要步驟和途徑，經濟全球化則是區(qū)域經濟集團化的最終歸宿。制約：但經濟區(qū)域集團化短期內對全球化不利。過渡：經濟全球化讓世界得以發(fā)展，但也有不公平的因素，那么，誰來維護公平了？二 、世界貿易組織的建立師：世界貿易組織建立的主要原因是什么？生：⑴經濟全球化的發(fā)展迅速；⑵關貿總協(xié)定存在許多弊端，不適應經濟全球化發(fā)展的要求師：它是怎樣建立起來的？生：①1986年： 意大利 提出倡議②1993年：烏拉圭回合談判——把多邊貿易組織改名為世界貿易組織③1994年： 正式決定建立WTO④1995.1.1：WTO正式開始運作師：世貿組織特點是什么？宗旨是什么？生：規(guī)范化 法制化。促進各國市場開放，調解貿易糾紛，實現(xiàn)全球范圍內的貿易自由化
人教版高中歷史必修2世界經濟的區(qū)域集團化說課稿2篇
一、 教材分析1、 教材地位和作用《當今世界的經濟區(qū)域集團化》是人教版《歷史②》（必修）第八單元第二課的內容。主要圍繞戰(zhàn)后世界經濟中出現(xiàn)的經濟區(qū)域集團化的趨勢，重點介紹了對世界經濟影響最大的三大區(qū)域集團：歐洲聯(lián)盟、北美自由貿易區(qū)和亞太經濟合作組織。從內容上既銜接了70年代布雷頓森林體系瓦解后80年代出現(xiàn)的經濟區(qū)域集團化的趨勢，又啟示了這種趨勢是經濟全球化趨勢的一部分，提出了下節(jié)課的主題。具有承上啟下的作用。2、 教學目標根據(jù)高中新課程標準和知識與能力、過程與方法、情感態(tài)度價值觀三者統(tǒng)一的要求，我將本節(jié)課的教學目標定為以下的三大方面：1) 知識與能力：能夠讓學生理解三大區(qū)域經濟集團建立的史實，認識三大區(qū)域經濟組織在世界經濟全球化進程中的影響和作用，增強學生辨證地觀察、分析歷史問題的能力。

3、總結(這部分要5分鐘)學生在教師的提示和問題的引導下，完成對本節(jié)課的知識的歸納和小結。利用簡煉、清晰的語言，再一次的突出本節(jié)課的重點，起到畫龍點睛的作用，培養(yǎng)了學生的表達能力。4、鞏固練習(這部分要10分鐘)用大屏幕投影把題目投影在屏幕上，讓學生思考，然后回答。這部分安排10分鐘的時間，讓學生思考完成具有針對性的練習，進行知識鞏固和教學效果反饋，及時糾正錯誤的理解和片面的認識。5、板書設計在板書中,我根據(jù)板書的“規(guī)范、工整和美觀”的要求，結合所學的內容，設計了如圖所示的板書。在其中，注重了重、難點的突出，使學生對知識的結構、層次、重點、難點一目了然，便于記憶和理解。四、效果分析對于反射的判斷，學生仍有可能出現(xiàn)錯誤，如刺激坐骨神經肌肉的收縮，教師應強調沒有完整的反射弧結構參與的不是反射。

二、典例解析例10. 如圖，正方形ABCD 的邊長為5cm ，取正方形ABCD 各邊的中點E,F,G,H, 作第2個正方形 EFGH，然后再取正方形EFGH各邊的中點I,J,K,L，作第3個正方形IJKL ，依此方法一直繼續(xù)下去. (1) 求從正方形ABCD 開始，連續(xù)10個正方形的面積之和；(2) 如果這個作圖過程可以一直繼續(xù)下去，那么所有這些正方形的面積之和將趨近于多少？分析：可以利用數(shù)列表示各正方形的面積，根據(jù)條件可知，這是一個等比數(shù)列。解：設正方形的面積為a_1，后續(xù)各正方形的面積依次為a_2, a_(3, ) 〖…,a〗_n,…，則a_1=25,由于第k+1個正方形的頂點分別是第k個正方形各邊的中點，所以a_(k+1)=〖1/2 a〗_k,因此{a_n}，是以25為首項，1/2為公比的等比數(shù)列.設{a_n}的前項和為S_n（1）S_10=(25×[1-(1/2)^10 ] )/("1 " -1/2)=50×[1-(1/2)^10 ]=25575/512所以，前10個正方形的面積之和為25575/512cm^2.(2)當無限增大時，無限趨近于所有正方形的面積和

人教版高中語文必修1《人性光輝：寫人要凸顯個性》說課稿2篇
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；

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.

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.

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.

情景導學古語云:“勤學如春起之苗,不見其增,日有所長”如果對“春起之苗”每日用精密儀器度量,則每日的高度值按日期排在一起,可組成一個數(shù)列. 那么什么叫數(shù)列呢?二、問題探究1. 王芳從一歲到17歲，每年生日那天測量身高，將這些身高數(shù)據(jù)（單位：厘米）依次排成一列數(shù)：75,87,96,103,110,116,120,128,138，145,153,158,160,162,163,165,168 ①記王芳第i歲的身高為 h_i ，那么h_1=75 , h_2=87, 〖"…" ，h〗_17=168.我們發(fā)現(xiàn)h_i中的i反映了身高按歲數(shù)從1到17的順序排列時的確定位置，即h_1=75 是排在第1位的數(shù)，h_2=87是排在第2位的數(shù)〖"…" ，h〗_17 =168是排在第17位的數(shù)，它們之間不能交換位置，所以①具有確定順序的一列數(shù)。2. 在兩河流域發(fā)掘的一塊泥板（編號K90，約生產于公元前7世紀）上，有一列依次表示一個月中從第1天到第15天，每天月亮可見部分的數(shù)：5,10,20,40,80,96,112,128,144,160,176,192,208,224,240. ②
