一、導(dǎo)入新課成為一位科學(xué)家是無數(shù)有志青年的夢想,對物理的探究更是許多年輕的學(xué)子孜孜以求的,我們來看一下加來道雄的成長道路,或許能得到一些啟發(fā)。(板書)一名物理學(xué)家的教育歷程二、明確目標1.引導(dǎo)學(xué)生從生活出發(fā),了解科學(xué)、認識科學(xué)2.引導(dǎo)學(xué)生以“教育歷程”為重點,探討其中表現(xiàn)的思想內(nèi)涵。三、整體感知1.作者簡介加來道雄,美籍日裔物理學(xué)家,畢業(yè)于美國哈佛大學(xué),獲加利福尼亞大學(xué)伯克利分校哲學(xué)博士學(xué)位,后任紐約市立大學(xué)城市學(xué)院理論物理學(xué)教授。主要著作有《超越愛因斯坦》(與特雷納合著)《量子場論》《超弦導(dǎo)論》。2.本文的基本結(jié)構(gòu)文章的題目是“一名物理學(xué)家的教育歷程”,因此,敘述的順序主要是歷時性的。但是,作者開頭就說“童年的兩件趣事極大地豐富了我對世界的理解力,并且引導(dǎo)我走上成為一個理論物理學(xué)家的歷程。”而“童年的兩件趣事”作為文章的主要內(nèi)容,又是共時性的敘述。這樣的結(jié)構(gòu)安排,使文章既脈絡(luò)清楚,又重點突出。

②林沖無辜受害,被刺配到滄州,遠離了京城,高俅一伙,陸謙、富安又追到滄州,在李小二的酒店里密謀陷害林沖。林沖從李小二那里聽說了這件事之后是什么態(tài)度?表現(xiàn)出林沖的什么性格?明確:林沖聽到李小二的報信,并確知從東京來的尷尬人就是陸虞候時,馬上意識到“那潑賤賊”是要“來這里害我”,他識破了仇人的陰謀,激起了復(fù)仇的怒火,氣憤地說:“休要撞著我,只叫他骨肉為泥!”說罷,便怒沖沖地“先去街上買把解腕尖刀,帶在身上,前街后巷一地里去尋”,次日,“帶了刀,又去滄州城里城外,小街夾巷,團團尋了一日”。這說明,當(dāng)迫害逼到眼前時,林沖也具有了強烈的反抗意識。但是,“街上尋了三五日,不見消耗”時,“林沖也自心下慢了”,對仇人有所懷疑,卻失去了應(yīng)有的警惕性,剛剛點燃起來的復(fù)仇怒火又慢慢熄滅了。這說明林沖的反抗并不堅決,幻想得過且過,委曲求全。

【教學(xué)設(shè)計】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)語言。2、了解新詞新語,能正確評價和運用新詞新語。二、教學(xué)重難點:1、重點:認識并評價新詞新語。2、難點:如何評價新詞新語三、教學(xué)用時:一課時四、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,我會很高興:我還是有優(yōu)點的哦。現(xiàn)在如果有人說我可愛,我就會心里嘀咕了: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)如果大家留心就會發(fā)現(xiàn),類似這樣的詞語很多,在網(wǎng)上是特別流行,很新穎、獨特,誰來列舉幾個?(點評學(xué)生所列舉出的詞語)網(wǎng)絡(luò)上有新詞新語,其它媒體(如報刊、電視等)都有新詞新語。關(guān)于新詞新語的概念,一般認為,新近創(chuàng)造出來的詞語,或是舊詞新用,這樣的詞語就叫新詞新語。

一、語文學(xué)習(xí)中學(xué)生自我評價能力的培養(yǎng)1.營造氛圍,培養(yǎng)學(xué)生自我評價的意識。學(xué)生自我評價能力是教師長期培養(yǎng)的結(jié)果,而保護學(xué)生自我評價的熱情,更是持續(xù)自我評價的保證。在我們的實際教育教學(xué)中,教師一直處于評價的絕對主體,很少去關(guān)注學(xué)生自我評價意識和能力的培養(yǎng),學(xué)生常常不理解:為什么要認真聽講?為什么書寫要工整、為什么發(fā)言要積極?為什么老師、父母對考試分數(shù)會有那么高的要求?當(dāng)前出現(xiàn)的學(xué)生許多諸如“離家出走”、“毒殺親人”等教育、行為、品德方面的問題,我想其中除了家長、教師的評價意識和評價藝術(shù)等原因之外,學(xué)生的自我評價意識的缺乏是根本的原因。所以我認為,學(xué)生自我評價意識的培養(yǎng)刻不容緩。(1)熱情鼓勵,提供成功的心理體驗。在教學(xué)過程中,教師要善于發(fā)現(xiàn)、肯定學(xué)生自我評價的點滴進步,對于他們每一點進步都要真誠熱情地鼓勵。讓學(xué)生覺得我這么做,這么想是對的。讓學(xué)生在教師的鼓勵中體會到強烈的愛,感受到自己的進步,增強自己的信心。“心若在,夢就在!”教師的熱情鼓勵是一種強大的催化劑,促使學(xué)生在學(xué)習(xí)中樂于自我評價。

一、知識和能力目標本單元的核心教學(xué)內(nèi)容是“認物”。用英語確認周圍的常見事物比較符合英語初學(xué)者的實際情況。通過本單元教學(xué),使學(xué)生運用所學(xué)句型,去熟悉周圍事物的名稱;教學(xué)生學(xué)會在實際生活中如何確認事物。通過辨認物體,學(xué)生學(xué)到一些生詞,并鞏固所學(xué)句型。二、過程和方法目標教師要盡量使學(xué)生對課文中出現(xiàn)的句型能夠熟練上口,這樣,學(xué)生才能順利開展比較靈活的對話。教師可以用手勢,表情,動作等示意,幫助學(xué)生聽懂課堂教學(xué)內(nèi)容,但在實際操作中應(yīng)盡量避免“明知故問”的傾向,應(yīng)該采用應(yīng)用性原則;如:遮蓋物品、顯露局部、辨認物體、完形識別、圖形辨認等方法。三、情感態(tài)度和價值觀目標目標在學(xué)生學(xué)習(xí)過程中的作用至關(guān)重要,教師要幫助他們建立起一個切合自己實際的目標,通過漸進的學(xué)習(xí)以及一點一滴的進步,使他們逐步建立起成功感。成功越多,自信心就越強。

Don’t fight. =You can’t fight. (板書,教讀)教師把這些句子板書在黑板上,并請學(xué)生大聲整齊地讀祈使句和“can’t”句型,并讓學(xué)生注意兩種句型表達形式的不同和轉(zhuǎn)換,“Don’t …=You can’t…”;并對學(xué)生說:These are our school rules. (板書,教讀) You can’t break the school rules. Don’t break the school rules.(板書,教讀)步驟3 :Practicea. T: Now, each of the students is breaking one of these rules.Please finish 1a.學(xué)生看圖,完成1a的內(nèi)容,檢查答案并大聲朗讀校規(guī)。b. 聽錄音,完成1b,選出四位學(xué)生都違反了哪條校規(guī);聽之前,學(xué)生要讀會英文名。c. 請兩位學(xué)生朗讀1c部分的句型;要求學(xué)生兩人一組對話表演,SA扮演外校轉(zhuǎn)來新生,SB告知本校校規(guī)。(學(xué)生可經(jīng)過討論,多說出他們想到的校規(guī),不必只限于書上;教師應(yīng)給予幫助)2) 第二課時(2a~4)步驟1 :warming up of revisionT: What are the rules at your school?學(xué)生使用“can”或祈使句表達各條校規(guī);其中老師可引出“eat in the cafeteria outside”的表達。步驟2 :Practicea.T: Christina is an exchange student.

教學(xué)過程Step 1: warming-up Sing a song---------“food and drink” Step 2: Revision1 Dictation2 Revise: What kind of noodles would you like?I’d like …What size bowl of noodles would you like?I’d like…Step 3: Presentation1 show pictures of food, ask students say the words.2 Students read the newspaper ad in 3a. Fill in blanks with words in the box. Then read the ad together, the teacher explains some difficult language points.3 Check the answers Step 4 PracticeAsk students to finish 3b in the same way according to 3a.

Then ask students to read their partner’s ad. Then order food and drink from their partner.Step 6 Home workGroup work – make an ad about “food and drink”

三、教學(xué)建議第一課時:1. Lead in (Vocabulary)A) Before class, teacher should collect some pictures of working places. For example: Bank, TV Station, Restaurant, Police Station, Hospital ...B) In class, show students the pictures (PowerPoint, OHP). Ask students to tell the name of the working places and the name of the jobs.Shop assistant, doctor, actor, reporter, police office, waiter, bank clerk, studentC) Do exercise 1a and 3a.2. Bingo GameAsk groups of students to make up pairs of cards with a job on one and the related workplace on the other. For example, waiter / restaurant, teacher / school, doctor / hospital. Encourage students to use both the job / workplace combinations in the book and the ones that students came up during class discussions. Be sure they have twice as many sets of cards as there are students in the group. They can make two sets of cards for a single job / workplace, if necessary. Then have each group mix up its set of cards and hand their cards out in random order. Each time a student gets a pair of cards that match, he or she can lay these cards down. The goal is to have no cards in your hand at the end.3. Task OneA) Ask students to work in pairs and ask the partner what does he / she want to be in the future.e. g. :What do you / does he / does she want to be?I want to be a.Why?Because it's (adj).B) Vocabulary: Section B, 1a4. Homework 1.2.

1 Each group choose one place to describe and what you are doing in it Choose one place, and describe what they are doing 2 Move around the room and give suggestions Talk about it and write it down 3 Ask one to show their works and act it Choose one of each group to make a report 4 Evaluate the best group and the best reporter Choose the best one Homework Ask your friends their ideal place and write about it教學(xué)反思:新課程標準中強調(diào)學(xué)生在課堂中的主體地位,在綜合課中他們的主體地位就更加突出。在各個活動中給不同程度的學(xué)生不同層次的任務(wù),讓各層面的學(xué)生都有表現(xiàn)發(fā)揮的機會,從而產(chǎn)生對英語的興趣。使用照片圖片多媒體來輔助教學(xué),效果更好。同時讓了解其他國家風(fēng)景,風(fēng)俗的同學(xué)介紹ideal place,增加學(xué)生的背景知知識,實現(xiàn)跨學(xué)科交流的目的。教案點評:采用任務(wù)型教學(xué)模式,在各個活動中給不同程度的學(xué)生不同層次的任務(wù),讓各層面的學(xué)生都有表現(xiàn)發(fā)揮的機會,從而產(chǎn)生對英語的興趣。使用照片圖片多媒體來輔助教學(xué),效果更好。讓了解其他國家風(fēng)景,風(fēng)俗的同學(xué)介紹ideal place,增加學(xué)生的背景知識,實現(xiàn)跨學(xué)科交流的目的。
