人教A版高中數(shù)學(xué)必修一函數(shù)的概念教學(xué)設(shè)計(jì)（2）
函數(shù)在高中數(shù)學(xué)中占有很重要的比重，因而作為函數(shù)的第一節(jié)內(nèi)容，主要從三個(gè)實(shí)例出發(fā)，引出函數(shù)的概念.從而就函數(shù)概念的分析判斷函數(shù)，求定義域和函數(shù)值，再結(jié)合三要素判斷函數(shù)相等.課程目標(biāo)1.理解函數(shù)的定義、函數(shù)的定義域、值域及對(duì)應(yīng)法則。2.掌握判定函數(shù)和函數(shù)相等的方法。3.學(xué)會(huì)求函數(shù)的定義域與函數(shù)值。數(shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象：通過教材中四個(gè)實(shí)例總結(jié)函數(shù)定義；2.邏輯推理：相等函數(shù)的判斷；3.數(shù)學(xué)運(yùn)算：求函數(shù)定義域和求函數(shù)值；4.數(shù)據(jù)分析：運(yùn)用分離常數(shù)法和換元法求值域；5.數(shù)學(xué)建模：通過從實(shí)際問題中抽象概括出函數(shù)概念的活動(dòng)，培養(yǎng)學(xué)生從“特殊到一般”的分析問題的能力，提高學(xué)生的抽象概括能力。重點(diǎn)：函數(shù)的概念，函數(shù)的三要素。難點(diǎn)：函數(shù)概念及符號(hào)y=f(x)的理解。

新人教版高中英語(yǔ)必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學(xué)設(shè)計(jì)
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.
人教版高中地理必修1第二章第四節(jié)全球氣候變化教案
氣候變化對(duì)健康的影響 氣候變化對(duì)人體健康的不良影響是不難發(fā)現(xiàn)的：熱浪沖擊頻繁加重可致死亡率及某些疾病、特別是心臟呼吸系統(tǒng)疾病發(fā)病率增加；對(duì)氣候變化敏感的傳染性疾病如瘧疾和登革熱的傳播范圍可能增加。極端氣候事件, 如干旱、水災(zāi)、暴風(fēng)雨等, 使死亡率、傷殘率及傳染病疾病率上升, 并增加社會(huì)心理壓力。某些媒介疾病的加重也可能與氣候變化有間接的關(guān)系, 如瘧疾是通過蚊子傳播的疾病,氣候變化可能使某些變暖地區(qū)的蚊子數(shù)目增加, 從而加重了瘧疾的發(fā)生。我國(guó)1994年瘧疾的發(fā)病率為5.3408/10萬(wàn), 居全國(guó)法定傳染病的第六位。血吸蟲病的發(fā)展與高溫及灌溉系統(tǒng)的擴(kuò)增有關(guān)。我國(guó)1994年南方12省市血吸蟲病患者的檢出率高達(dá)3.67%，不能忽視氣候變化對(duì)此的可能影響。還有一些疾病，如睡眠病、登革熱、黑熱病等也有與氣候關(guān)系的報(bào)道。另外, CO2、一些空氣污染物如氮氧化物、臭氧等可增加過敏疾患及心臟呼吸系統(tǒng)疾病和死亡。

【教學(xué)設(shè)計(jì)】一、教學(xué)目的：1、引導(dǎo)學(xué)生關(guān)注生活，向生活學(xué)習(xí)語(yǔ)言。2、了解新詞新語(yǔ)，能正確評(píng)價(jià)和運(yùn)用新詞新語(yǔ)。二、教學(xué)重難點(diǎn)：1、重點(diǎn)：認(rèn)識(shí)并評(píng)價(jià)新詞新語(yǔ)。2、難點(diǎn)：如何評(píng)價(jià)新詞新語(yǔ)三、教學(xué)用時(shí)：一課時(shí)四、教學(xué)過程預(yù)設(shè)（一）導(dǎo)入新課以前如果有人說我可愛，我會(huì)很高興：我還是有優(yōu)點(diǎn)的哦?，F(xiàn)在如果有人說我可愛，我就會(huì)心里嘀咕了：這是什么意思呀？同學(xué)們知道這有什么意思嗎？（可愛=可憐沒人愛）如果大家留心就會(huì)發(fā)現(xiàn)，類似這樣的詞語(yǔ)很多，在網(wǎng)上是特別流行，很新穎、獨(dú)特，誰(shuí)來列舉幾個(gè)？（點(diǎn)評(píng)學(xué)生所列舉出的詞語(yǔ)）網(wǎng)絡(luò)上有新詞新語(yǔ)，其它媒體（如報(bào)刊、電視等）都有新詞新語(yǔ)。關(guān)于新詞新語(yǔ)的概念，一般認(rèn)為，新近創(chuàng)造出來的詞語(yǔ)，或是舊詞新用，這樣的詞語(yǔ)就叫新詞新語(yǔ)。

1．懸念法懸念法又稱關(guān)子。它是作者為了激發(fā)那種“緊張與期待的心理活動(dòng)”，在行文中有意采取的一種積極而有效的手段。這種手段包括“設(shè)懸”和“解懸”兩方面。所謂 “設(shè)懸”就是設(shè)置懸念，即在情節(jié)發(fā)生發(fā)展的關(guān)鍵時(shí)刻或人物命運(yùn)攸關(guān)的重要關(guān)頭，敘述戛然而止，轉(zhuǎn)敘他事。從而引起讀者強(qiáng)烈的尋根問底的興趣。所謂“解懸” 也叫“釋懸”，就是指在情節(jié)發(fā)展的特定階段，通過矛盾的解決，揭示事情原委和人物命運(yùn)的結(jié)局，使讀者的期待心理得以滿足。如《驛路梨花》，當(dāng)人們正為露宿而發(fā)愁時(shí)出現(xiàn)了一間神秘的小屋，小屋的主人是誰(shuí)呢？猜想間，有人來了，但也不是屋子主人，那小屋子的主人是誰(shuí)呢？終于知道了小屋是解放軍蓋的，但為什么要蓋這間小屋呢？這樣“設(shè)懸——釋懸——帶出新懸念”，環(huán)環(huán)相扣、層層遞進(jìn)，使文章韻味無窮。

二．運(yùn)用思考題目，激發(fā)學(xué)生對(duì)本課問題的探究，檢查學(xué)生在學(xué)習(xí)過程中，結(jié)合所學(xué)的知識(shí)，對(duì)問題的思考、質(zhì)疑；從而學(xué)會(huì)查閱、搜集資料，分析、整理；通過討論、交流，得出新的認(rèn)識(shí)。學(xué)生可根據(jù)自己的實(shí)際情況和個(gè)人愛好，可選擇不同的作業(yè)呈現(xiàn)方式，包括作業(yè)的問題的選擇、繳交的方式（制作、小論文、課件）等等，從而體現(xiàn)學(xué)生對(duì)古代希臘雅典民主政治產(chǎn)生的條件、雅典民主政治的內(nèi)容及其意義的認(rèn)識(shí)的程度。1．“東西方不同政治制度選擇的因素分析”（課前）2．古代雅典民主政治制度對(duì)人類文明的影響。（課后）七．反思與總結(jié)本課的設(shè)計(jì)在實(shí)施過程中,總體效果比較好，對(duì)課標(biāo)的要求基本達(dá)至。尤其是通過東西方不同政治制度選擇的對(duì)比，不但復(fù)習(xí)了舊的知識(shí)，而且加深了對(duì)新知識(shí)的掌握，從而有更深入的認(rèn)識(shí)。學(xué)生在這個(gè)問題的學(xué)習(xí)過程中，通過課前自身的活動(dòng)（搜集、查閱資料），逐步培養(yǎng)歷史的學(xué)習(xí)的方法；在課堂上，同學(xué)們通過討論的過程，互相交流、分享心得體會(huì)；逐步提高自己的思維能力。
