(一).知識(shí)方面: 1.培養(yǎng)學(xué)生能運(yùn)用過(guò)去進(jìn)行時(shí)來(lái)描述、談?wù)撨^(guò)去某個(gè)時(shí)間正在發(fā)生的事情或動(dòng)作的意識(shí)和能力,能就過(guò)去某個(gè)時(shí)間正在發(fā)生的動(dòng)作做出正確的描述。 2.培養(yǎng)學(xué)生的想象力和角色扮演的合作能力。 3.培養(yǎng)學(xué)生講述過(guò)去發(fā)生的事情經(jīng)過(guò)的能力。能正確運(yùn)用一般過(guò)去時(shí)來(lái)講述故事。 (二).技能方面: 1.本單元的語(yǔ)言目標(biāo)是Talk about past events and tell a story(談?wù)撨^(guò)去的時(shí)間和講述一個(gè)故事),圍繞這一目標(biāo),要涉及句型: What were you doing when the UFO arrived? ----I was sitting in the barber’s chair. The barber was cutting my hair. 因此必須學(xué)習(xí)standing、studying、cleaning、sleeping、cooking、making、eating、cutting、等表示地點(diǎn)的詞,以便為上述句型提供語(yǔ)言材料。2.學(xué)習(xí)過(guò)去進(jìn)行時(shí)的有關(guān)知識(shí)。Was/were+現(xiàn)在分詞,是該時(shí)態(tài)的表達(dá)式。 3.在學(xué)習(xí)過(guò)程中,要區(qū)分The boy was walking down the street when the UFO landed.和While the boy was walking down the street, the UFO landed.這兩種由when和while引導(dǎo)的狀語(yǔ)從句的句型結(jié)構(gòu)。注意它們的不同。

"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it?

第三環(huán)節(jié)。嘗試練習(xí),信息反饋。讓學(xué)生嘗試練習(xí):課本p152第3題,并引導(dǎo)中下學(xué)生看p152例題,教師及時(shí)點(diǎn)撥講評(píng)?!鹘處煱才胚@一過(guò)程,完全放手讓學(xué)生自主進(jìn)行,充分暴露學(xué)生的思維過(guò)程,展現(xiàn)學(xué)生生動(dòng)活潑、主動(dòng)求知和富有的個(gè)性,使學(xué)生真正成為學(xué)習(xí)的主體,使因式分解與整式的乘法的關(guān)系得到正強(qiáng)化。第四環(huán)節(jié)。小結(jié)階段。這是最后的一個(gè)環(huán)節(jié),教師出示“想一想”:下列式子從左邊到右邊是因式分解嗎,為什么?學(xué)生展開(kāi)討論,得到下列結(jié)論:A.左邊是乘法,而右邊是差,不是積;B.左右兩邊都不是整式;C.從右邊到左邊是利用了因式分解的變形方法進(jìn)行分解。由此可知,上式不是因式分解。進(jìn)而,教師呈現(xiàn)因式分解定義。△教師安排這一過(guò)程意圖是:學(xué)生一般到臨近下課,大腦處于疲勞狀態(tài),注意力開(kāi)始分散。
教學(xué)設(shè)計(jì)說(shuō)明:本節(jié)課從學(xué)生接觸到的實(shí)際問(wèn)題出發(fā),結(jié)合新課程標(biāo)準(zhǔn)的理念,創(chuàng)造性地使用教材而設(shè)計(jì)的一節(jié)課,是前面線段的比、成比例線段等知識(shí)在現(xiàn)實(shí)生活中的應(yīng)用. 一開(kāi)始情境的創(chuàng)設(shè)——彩色圖片的投影,給學(xué)生以美的感覺(jué),激發(fā)學(xué)生的求知欲.通過(guò)實(shí)際生活中的例子,讓學(xué)生自己發(fā)表自己的看法,培養(yǎng)學(xué)生的審美情趣,又從學(xué)生最感興趣的奧運(yùn)會(huì)的比賽中引出今天所要學(xué)習(xí)的內(nèi)容,從而進(jìn)一步培養(yǎng)學(xué)生的愛(ài)國(guó)主義情感.在教學(xué)設(shè)計(jì)中,充分發(fā)揮了學(xué)生的主觀能動(dòng)性,通過(guò)小組討論,師生間的合作交流,解決了本節(jié)課的重點(diǎn)和難點(diǎn).讓每個(gè)學(xué)生都能從同伴的交流中獲益,同時(shí)也培養(yǎng)了學(xué)生的合作意識(shí),提高了學(xué)生的動(dòng)手操作的能力.本節(jié)課在教學(xué)設(shè)計(jì)中主要運(yùn)用了引導(dǎo)探究、分組討論的教學(xué)方法;引導(dǎo)學(xué)生自主探究、合作交流的研討學(xué)習(xí)方式,確立了學(xué)生的主體地位.
用你的語(yǔ)言描述一下配方法解一元二次方程的基本步驟和需注意的問(wèn)題。 教師引導(dǎo)學(xué)生進(jìn)行反思、歸納配方法解一元二次方程的基本思路、步驟及注意事項(xiàng)。鞏固對(duì)課堂知識(shí)的理解和掌握,同時(shí)進(jìn)一步體會(huì)解一元二次方程時(shí)降次的基本策略和轉(zhuǎn)化的思想。 六、布置作業(yè)分層布置作業(yè),既鞏固本節(jié)主要內(nèi)容,又有讓學(xué)有余力的學(xué)生有思考和提升的空間。思考題為后面深入研究配方法,完善對(duì)配方法的認(rèn)識(shí)做準(zhǔn)備。 同時(shí)讓學(xué)生感受到數(shù)學(xué)學(xué)習(xí)在實(shí)際生活中的作用,感受數(shù)學(xué)的美。五、板書(shū)設(shè)計(jì)我將板書(shū)分成了兩部分,重點(diǎn)突出這節(jié)課用配方法解一元二次方程的步驟,在配以適當(dāng)?shù)木毩?xí),簡(jiǎn)單明了,重點(diǎn)突出。六、教學(xué)評(píng)價(jià)與反思本節(jié)課我根據(jù)學(xué)生的特點(diǎn)采用合作交流探究式學(xué)西方法教學(xué),讓學(xué)生動(dòng)起來(lái),感受數(shù)學(xué)學(xué)習(xí)的樂(lè)趣。讓學(xué)生更加愛(ài)學(xué)數(shù)學(xué)。
1.多媒體的合理應(yīng)用,可極大的激發(fā)學(xué)生的學(xué)習(xí)興趣,提高教學(xué)效果.在本節(jié)課的“情境引入”這一教學(xué)環(huán)節(jié)中,用媒體展示的人影、皮影、手影的精彩圖片,用媒體播放的皮影戲、手影戲視頻片斷給學(xué)生以視覺(jué)沖擊,產(chǎn)生了視覺(jué)和心理的震撼,這樣在課堂“第一時(shí)間”抓住了學(xué)生的注意力、極大的激發(fā)了學(xué)生的學(xué)習(xí)熱情,將十分有利于后面教學(xué)活動(dòng)的開(kāi)展,提高課堂教學(xué)效果.2.附有挑戰(zhàn)性的“問(wèn)題(或活動(dòng))”、層層深入的“問(wèn)題串”可激發(fā)學(xué)生的探索欲望,培養(yǎng)創(chuàng)新精神,拓展思維能力.在本節(jié)課“探究活動(dòng)”這一教學(xué)環(huán)節(jié)中的“做一做”設(shè)計(jì)的4個(gè)活動(dòng),由簡(jiǎn)單的“模仿”到“創(chuàng)作設(shè)計(jì)、觀察思考”循序漸進(jìn)、挑戰(zhàn)性逐漸增大,不斷激發(fā)學(xué)生的探索欲望,引人入勝,培養(yǎng)創(chuàng)新精神,拓展能力.再如,在本節(jié)課“數(shù)學(xué)運(yùn)用”這一教學(xué)環(huán)節(jié)中的“例2”設(shè)計(jì)的2個(gè)問(wèn)題層層深入,現(xiàn)實(shí)情境味很濃,學(xué)生做起來(lái)饒有興趣.

1. Do some exercise on the paper. There are four kinds of exercise here. The exercise 1 is to develop Ss’ ability of listening. Exercise 2 is to practice Ss’ ability of knowing the words. Exercise 3 is to develop Ss’ ability of speaking numbers and letters. Exercise 4 is to make Ss know the words and letters well. These exercises can consolidate the new knowledge from different styles of problems.2. Then tell Ss that we can sing the numbers like “ Do, re, mi, fa, so, la, ti, do” and let them listen to a song named “Do, Re, Mi”. Add some extra knowledge so that Ss will be glad to see that the numbers can be used in another way.Step 4 Homework1.Read the numbers from 1 to 7 and 7 to 1 five times.2.Read the letters “u, v, w” five times follow the tape.Reading is a useful way for the Ss of Grade One to practice the knowledge.
