本環(huán)節(jié)我依據(jù)教學目標和學生對知識的掌握情況,我設(shè)計了有針對性、層次分明的練習題(基本題、變式題、拓展題),讓學生在解決這些問題的過程中,進一步理解,鞏固新知,訓練思維的靈活性,使學生的探索精神和實踐能力得到進一步的提高。[本環(huán)節(jié)的設(shè)計意圖:通過多層次的練習,激發(fā)學生的學習興趣,調(diào)動學生學習的積極性和主動性,使學生獲得愉悅的情感體驗。同時使學生的知識結(jié)構(gòu)更加完善。]第四環(huán)節(jié):課堂小結(jié)在輕松愉快的學習活動結(jié)束后,我會與學生進行總結(jié)對話“這節(jié)課你有什么收獲?你學會了什么?還有什么不懂得地方嗎?”學生充分發(fā)言,交流自己的學習心得。[本環(huán)節(jié)的設(shè)計意圖:幫助學生梳理知識,整理本課的知識要點,完成本節(jié)課的教學活動。]

三、教學建議第一課時: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.

句型: Where did you go on vacation? I went to summer camp.Did she go to Central Park?Yes,she did.No, she didn’t語法:一般過去時特殊疑問句、一般疑問句及肯、否定回答。課時安排4課時第一課時:Section A:la,1b,lc,2a,2b,2c 第二課時:Section A:3a,3b,4第三課時:Section B:1,2a,2b,2c第四課時:Section B:3a,3b,3c,4 and Self Check第一課時教學目標掌握描寫假期生活的形容詞。假期里自己所做事情的簡單表達。談?wù)摷倨谧龅氖虑榧爱敃r情況。談?wù)摷倨跁r旅游的天氣,旅游者以及食物等。教學過程一、導入播放一首英文歌曲:Let’s travel 說明:通過讓學生聽節(jié)奏歡快迪斯尼英語歌曲Let’s travel.引入本節(jié)課談?wù)摰脑掝}vacation and travel. 讓歌曲使學生的思維活躍,增強課堂氣氛,激發(fā)學生提高學習英語的興趣。T:How is the trip ?Ss : It’s pretty good/ happy/exciting /relaxing/busy/dangerous/ fantastic說明:這個問題是為了操練形容詞。建議讓多個Ss作答。鼓勵他們用不同的形容詞。上述個別形容詞本應(yīng)在第二課時中出現(xiàn),但可以在warming-up中第一次非正式出現(xiàn)。這些形容詞也可在老師的評價語中適時出現(xiàn),以加深學生對詞匯的印象。

單元整體說明(一)單元教材分析本單元的核心話題是描述動物和表達個人喜好,以及句式why do you like…? Because…。這也是本單元的教學重點。通過本單元的學習,學生應(yīng)能較流利地運用所學詞匯和句型描述動物,表達個人喜好。(二)單元知識結(jié)構(gòu)1.詞匯動物名稱 tiger, elephant, koala, dolphin, etc.詞匯描述性形容詞: smart, cute, ugly, clever, shy, etc.國家名: Australia, South Africa2.句型Why do you like koala hears? Because they are cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(三)單元整體目標1.Master the vocabulary2.Master and use: Why do you like koalas? Because they am cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(四)單元教學重難點一覽(五)單元學情分析學生此前已經(jīng)學過由why, where, what 引導的特殊疑問句句型,具有了學習本單元知識的認知前提。形形色色的動物能激發(fā)學生的好奇心,產(chǎn)生了解它們的欲望,這有利于本單元知識的教學和學生學習興趣的培養(yǎng)。

所需要用到的句子:Who is that?That is Jack. I like him.Why do you like him?I like him because he is interesting.Task 4: 設(shè)計理想中的人類Step one: 設(shè)計理想中的人類的外貌。把全班同學分成若干小組,學生可以邊說邊在紙上畫出他們的模樣。Step two: 設(shè)計理想中人類的性格。學生們可以把那些能描述性格的單詞寫在圖畫的旁邊。Step three: 每組選出一名同學,其他同組同學提問,他作簡單回答,并說明原因。所需用到的句子:What does he or she look like?He or she ...What is he or she like?He or she is ...Why?Because ...Task 5: 挑戰(zhàn)性活動調(diào)查性格是天生的還是后天形成的,讓每個同學回家去調(diào)查一下自己成長過程中性格是否有變化,具體是怎樣的,為什么會這樣? Teaching Aims:1. Enable students to have a general understanding of how to talk about people's physical appearance.2. Enable students to tackle some essential vocabularies and patterns about describing people. Provide them with necessary skills and methods.3. Create various chances for students to describe the persons they're familiar with, such as classmates, family members, teachers, idols, etc.

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教學反思:新課程標準中強調(diào)學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生不同層次的任務(wù),讓各層面的學生都有表現(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,效果更好。同時讓了解其他國家風景,風俗的同學介紹ideal place,增加學生的背景知知識,實現(xiàn)跨學科交流的目的。教案點評:采用任務(wù)型教學模式,在各個活動中給不同程度的學生不同層次的任務(wù),讓各層面的學生都有表現(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,效果更好。讓了解其他國家風景,風俗的同學介紹ideal place,增加學生的背景知識,實現(xiàn)跨學科交流的目的。

五、教學Section B-2c1. Pair work: What do you think of the belt/sunglasses/…? What does your father/mother/… think of your scarf/belt…?2. Group work(1). Teacher shows some different kinds of school uniforms (制服)and asks : “ What do you think of your school uniforms?

Discuss in groups.(3).Get some Ss to report in class.說明:這一步旨在讓學生運用已有的語言知識談?wù)搶κ挛锏目捶ê鸵庖?,并簡單闡明理由,培養(yǎng)學生的主動思維能力和運用英語的能力。六、教學拓展調(diào)查電視節(jié)目的收視率任務(wù):調(diào)查你周圍的人對現(xiàn)在各種電視節(jié)目的反響。活動過程:1.教師布置任務(wù),讓學生調(diào)查周圍的人(包括他的親戚朋友和鄰居)喜歡收看哪方面的電視節(jié)目。2.學生進行調(diào)查活動,運用本單元所學的句型What do you think of….? (Why?)What's your favorite game shows?What do you think of talk show?I doesn’t mind it.I like it.I love it.I can’t stand it.3.記錄下排在前10位的TV Program,填寫調(diào)查表,比較其收視率。

教學難點:讓學生經(jīng)歷比較簡單分數(shù)大小的過程,并能解決簡單的實際問題.設(shè)計本課時,我注重為學生創(chuàng)設(shè)恰當?shù)膮⑴c,實踐探究必備的空間,讓學生在主動參與學習活動的過程中,引導學生有效思考,撐握簡單分數(shù)大小比較的方法,活動重在讓學生經(jīng)歷探索與發(fā)現(xiàn)的過程,使其在課堂中既有獲取知識,能力也得到了培養(yǎng)。本科課堂教學我從學生感興趣的游戲和故事兩方面入手:游戲?qū)τ诤⒆右恢笔歉信d趣的話題,同分母分數(shù)比較大小在了解分數(shù)的意義之后,對于學生學習這一部分來說是比較簡單的,如何提高學生的學習興趣,我脫離書本這一載體設(shè)計了莫分數(shù)比大小這一游戲,在課堂上學生自主地參與活動,通過讓學生動手做、動腦想:你想摸到幾顆棋子?為什么?、動口說:比這個分數(shù)大的分數(shù)還有?比這個分數(shù)小的分數(shù)還有?,使學生在活動中發(fā)現(xiàn)問題分母相同的分數(shù)如何比較大???尋求規(guī)律分母相同的分數(shù)比較大小的方法。

1、教學內(nèi)容九年義務(wù)教育六年制小學數(shù)學教科書(北師大版)四年級下冊第27頁至29頁的內(nèi)容及相關(guān)練習題。2、教材簡析“三角形分類”是新課程教材中“空間與圖形”領(lǐng)域內(nèi)容的一部分。學生在學習此內(nèi)容之前,已經(jīng)學習了三角形的認識,能夠在物體的面中找出三角形,學習了角的知識,認識了常見的角,為學生研究三角形的特征,從角和邊的不同角度對三角形進行分類做好了有力的知識支撐。三角形是最簡單也是最基本的多邊形,一切多邊形都可以分割成若干個三角形,學好這部分內(nèi)容,為學習其他多邊形積累了知識經(jīng)驗,為進一步學習三角形的有關(guān)知識打下了基礎(chǔ)。3、教學目標根據(jù)教材的內(nèi)容及學生的知識現(xiàn)狀和年齡心理特點,我制定了以下教學目標。①知識目標;學生通過觀察、操作、比較、發(fā)現(xiàn)三角形角和邊的特征,會給三角形分類,理解并掌握各種三角形的特征。

一、說教材《圖形分類》是北師大版小學數(shù)學四年級下冊第二單元《認識三角形和四邊形》的第一個教學內(nèi)容。本節(jié)內(nèi)容正是在學生已經(jīng)直觀認識了一些圖形的基礎(chǔ)上,通過分類整理,進一步了解圖形的類別特征,感受它們之間的聯(lián)系,同時滲透了分類的數(shù)學思想,積累了數(shù)學活動經(jīng)驗。教科書安排了兩個問題:第一個問題是通過分類活動初步認識圖形類別特征;第二個問題是在操作活動中發(fā)現(xiàn)三角形的穩(wěn)定性;而后設(shè)計練一練,讓學生能運用所學的知識解釋生活現(xiàn)象,感受數(shù)學與生活的緊密聯(lián)系。二、說教法、學法1、多媒體教學法。在教學中教師能夠充分利用多媒體教學課件進行教學,這樣比較直觀形象,有助于學生理解,也調(diào)動了學生學習的積極性。2、自主探究法。課堂上每遇到一個問題,教師總讓學生說理由,給學生留足較大的時間空間,讓他們很好的獨立思考,親身經(jīng)歷問題解決的過程,體驗學習成功的樂趣。

三、估算度的把握。《標準》在計算教學方面強調(diào)的內(nèi)容之一是重視估算,培養(yǎng)估算意識。我們認為重視估算,就是對學生數(shù)感的培養(yǎng),具體體現(xiàn)在能估計運算的結(jié)果,并對結(jié)果的合理性作出解釋。本節(jié)課的設(shè)計就是讓學生在具體情境中,學會兩種估算方法,結(jié)合具體情況作出合理解釋。四、教會學生單元整理與復習的方法,使學生終身受益。我們知道授人以漁而非魚的道理。在本節(jié)課中,老師設(shè)計了引導學生學會整理與復習的方法,如:帶著問題看書,將算式分類、歸納、總結(jié)出本單元所學內(nèi)容,計算方法,注意地方,最后進行有針對性的練習。如果我們的老師從小就有意識地對學生進行學習方法的培養(yǎng),學生將終身受益。我想我們教學研討活動就是為了實現(xiàn)教育的最高境界:今天的教是為了明天的不教。

三、暢意表達,理解英雄1.暢意表達。師:通過學習課文,你們明白了楊利偉為什么被稱為“航天英雄”嗎?請同學們大膽表達自己的想法。(生自由交流回答)預設(shè) 楊利偉是中國人民解放軍航天員大隊的首飛航天員,圓滿完成了中國的第一次載人航天飛行任務(wù)。在充滿不可預料的各種危險和意外的情況下,楊利偉為了國家、民族的利益奮不顧身,他具有不怕犧牲、敢于犧牲的大無畏精神和拼搏勇氣,所以被稱為“航天英雄”。2.理解英雄。師:是否只有為國捐軀者才能成為英雄呢?請同學們四人一小組討論一下,然后說說你們組的意見。(生小組內(nèi)交流討論后,推薦代表在全班交流,師指導明確)預設(shè) 不是的。凡是為了國家、民族的利益而不顧個人安危,并為此奉獻出自己的智慧和力量的人,都應(yīng)該給予英雄的榮譽。楊利偉在中國的第一次載人航天飛行中,遇到許多突發(fā)事件,危難考驗不時出現(xiàn),如果沒有大無畏的精神,沒有為國家、民族做貢獻的意識,是不可能臨危不懼、堅持到底的。

二、升格訓練師:大文豪曹雪芹寫《紅樓夢》是“披閱十載,增刪五次”,可見修改是寫作獲得成功的必然環(huán)節(jié),很多文學名家對此也深有感觸。這些古今中外的作家,都向我們推薦了一種修改文章的好方法——朗讀修改法。結(jié)合你自己的寫作經(jīng)驗,你覺得大聲朗讀可以發(fā)現(xiàn)習作中的哪些問題?預設(shè) 如有些詞語聽起來不順耳,有些句子讀起來不順口,有些段落缺少過渡,或前后意思重復,有些地方表達不清楚,有些修辭手法的運用欠妥,有些標點的運用不規(guī)范等,這些問題都能夠在朗讀中發(fā)現(xiàn)。2.再改隨筆。師:之前修改寫景隨筆,用的是默讀修改法,這次換作朗讀修改法,會不會有新的收獲呢?請大家朗讀病文,然后小組討論:文中還有哪些用詞不恰當、語句不連貫的地方,找出來并進行修改,使之文從字順。(生朗讀隨筆,修改后交流討論并展示)預設(shè) (1)“有什么輕柔的東西拂到臉上,細細的”,可以把“輕柔的”改成疊詞“柔柔的”,放到后面,和“細細的”并列,這樣讀起來音律感要好些。

師小結(jié):以簡代繁,是讓語言簡明的又一方法。除了常用的人稱可以替代,還可以對不必要的具體內(nèi)容進行概述,以達到簡明的效果。替代的詞句要巧,既要簡潔,又不能改變原意。由此我們可以總結(jié)出語言簡明的另一種方法:“語言簡明”的方法:④巧用替代法——善于概括,巧用指代。師補充:漢語是一種非常豐富的語言,它的許多表達形式都是以簡明為原則而形成的,像成語、簡稱、緊縮句、合說等。我們在運用語言時,可以適當?shù)剡x用這些表達形式,使語言達到簡明。需要注意的是,簡明與否不能單純以字數(shù)多少為標準,要從語言表達的需要出發(fā),當簡則簡,當繁則繁。不能為了“簡”而影響“明”,甚至讓人產(chǎn)生誤解。歸納這節(jié)課的學習要點,讓學生將其內(nèi)化為自身的語言意識并參與寫作實踐,學以致用,訓練使語言“簡明”的能力,培養(yǎng)良好的寫作習慣。
