為了使學(xué)生能在視、聽、說、思等幾個環(huán)節(jié)中經(jīng)歷學(xué)習(xí)的過程,體驗學(xué)習(xí)語文的樂趣,順利達(dá)成教學(xué)目標(biāo),我設(shè)計的教學(xué)過程如下:1.觀察交流、激發(fā)興趣、情景導(dǎo)入為了能讓學(xué)生更好的體會靜夜,我設(shè)計了這一環(huán)節(jié)。在上新課前一晚,布置學(xué)生去觀察夜晚的天空,然后上課時把自己觀察到夜空的內(nèi)容和感受,說給同學(xué)聽,大家互相交流下。交流后引入新課:靜夜思。課題引入后,給學(xué)生解釋下課題,讓學(xué)生思考一下,詩人是在什么時候思念,又思念些什么?提問后,把遠(yuǎn)程教育碟片切到《靜夜思》這課,讓學(xué)生欣賞課文。2.初讀古詩,整體感知,認(rèn)讀生字我設(shè)計這一環(huán)節(jié),是想讓學(xué)生通過自己朗讀課文,去發(fā)現(xiàn)這課的生字,并在這環(huán)節(jié)中,要求學(xué)生利用拼音幫助自己讀準(zhǔn)每個字,尤其是一些后鼻音,讓學(xué)生成為學(xué)習(xí)的主人。
三、說教學(xué)目標(biāo)1.會認(rèn)“芬、芳”等10個生字,會寫“斗、芬”等13個生字。能正確讀寫“爭奇斗艷、芬芳”等詞語;結(jié)合語境理解詞語;背誦課文第1自然段。2.讀懂課文內(nèi)容,激發(fā)學(xué)生觀察興趣,初步培養(yǎng)學(xué)生留心周圍事物,認(rèn)真觀察和思考的習(xí)慣。3.學(xué)習(xí)運用多樣的句式表達(dá),培養(yǎng)學(xué)生語言表達(dá)能力,培養(yǎng)學(xué)生美的情趣,激發(fā)熱愛大自然的思想感情。四、說教學(xué)重難點1.在理解課文的基礎(chǔ)上,理解不同的表達(dá)方式,對一些句子嘗試換一種說法。(重點)2.學(xué)習(xí)運用多樣的句式表達(dá);培養(yǎng)學(xué)生美的情趣,激發(fā)熱愛大自然的思想感情。(難點)五、說教法學(xué)法[說教法]通過自主、合作、探究的體驗性小組合作學(xué)習(xí)方式,讀中感悟、讀中體驗,采用“激趣——發(fā)現(xiàn)——感悟——實踐”的思路,引導(dǎo)學(xué)生在自主中學(xué)習(xí)本文。
高斯(Gauss,1777-1855),德國數(shù)學(xué)家,近代數(shù)學(xué)的奠基者之一. 他在天文學(xué)、大地測量學(xué)、磁學(xué)、光學(xué)等領(lǐng)域都做出過杰出貢獻(xiàn). 問題1:為什么1+100=2+99=…=50+51呢?這是巧合嗎?試從數(shù)列角度給出解釋.高斯的算法:(1+100)+(2+99)+…+(50+51)= 101×50=5050高斯的算法實際上解決了求等差數(shù)列:1,2,3,…,n,"… " 前100項的和問題.等差數(shù)列中,下標(biāo)和相等的兩項和相等.設(shè) an=n,則 a1=1,a2=2,a3=3,…如果數(shù)列{an} 是等差數(shù)列,p,q,s,t∈N*,且 p+q=s+t,則 ap+aq=as+at 可得:a_1+a_100=a_2+a_99=?=a_50+a_51問題2: 你能用上述方法計算1+2+3+… +101嗎?問題3: 你能計算1+2+3+… +n嗎?需要對項數(shù)的奇偶進(jìn)行分類討論.當(dāng)n為偶數(shù)時, S_n=(1+n)+[(2+(n-1)]+?+[(n/2+(n/2-1)]=(1+n)+(1+n)…+(1+n)=n/2 (1+n) =(n(1+n))/2當(dāng)n為奇數(shù)數(shù)時, n-1為偶數(shù)
我們知道數(shù)列是一種特殊的函數(shù),在函數(shù)的研究中,我們在理解了函數(shù)的一般概念,了解了函數(shù)變化規(guī)律的研究內(nèi)容(如單調(diào)性,奇偶性等)后,通過研究基本初等函數(shù)不僅加深了對函數(shù)的理解,而且掌握了冪函數(shù),指數(shù)函數(shù),對數(shù)函數(shù),三角函數(shù)等非常有用的函數(shù)模型。類似地,在了解了數(shù)列的一般概念后,我們要研究一些具有特殊變化規(guī)律的數(shù)列,建立它們的通項公式和前n項和公式,并應(yīng)用它們解決實際問題和數(shù)學(xué)問題,從中感受數(shù)學(xué)模型的現(xiàn)實意義與應(yīng)用,下面,我們從一類取值規(guī)律比較簡單的數(shù)列入手。新知探究1.北京天壇圜丘壇,的地面有十板布置,最中間是圓形的天心石,圍繞天心石的是9圈扇環(huán)形的石板,從內(nèi)到外各圈的示板數(shù)依次為9,18,27,36,45,54,63,72,81 ①2.S,M,L,XL,XXL,XXXL型號的女裝上對應(yīng)的尺碼分別是38,40,42,44,46,48 ②3.測量某地垂直地面方向上海拔500米以下的大氣溫度,得到從距離地面20米起每升高100米處的大氣溫度(單位℃)依次為25,24,23,22,21 ③
二、典例解析例3.某公司購置了一臺價值為220萬元的設(shè)備,隨著設(shè)備在使用過程中老化,其價值會逐年減少.經(jīng)驗表明,每經(jīng)過一年其價值會減少d(d為正常數(shù))萬元.已知這臺設(shè)備的使用年限為10年,超過10年 ,它的價值將低于購進(jìn)價值的5%,設(shè)備將報廢.請確定d的范圍.分析:該設(shè)備使用n年后的價值構(gòu)成數(shù)列{an},由題意可知,an=an-1-d (n≥2). 即:an-an-1=-d.所以{an}為公差為-d的等差數(shù)列.10年之內(nèi)(含10年),該設(shè)備的價值不小于(220×5%=)11萬元;10年后,該設(shè)備的價值需小于11萬元.利用{an}的通項公式列不等式求解.解:設(shè)使用n年后,這臺設(shè)備的價值為an萬元,則可得數(shù)列{an}.由已知條件,得an=an-1-d(n≥2).所以數(shù)列{an}是一個公差為-d的等差數(shù)列.因為a1=220-d,所以an=220-d+(n-1)(-d)=220-nd. 由題意,得a10≥11,a11<11. 即:{█("220-10d≥11" @"220-11d<11" )┤解得19<d≤20.9所以,d的求值范圍為19<d≤20.9
情景導(dǎo)學(xué)古語云:“勤學(xué)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(chǎn)于公元前7世紀(jì))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
課前小測1.思考辨析(1)若Sn為等差數(shù)列{an}的前n項和,則數(shù)列Snn也是等差數(shù)列.( )(2)若a1>0,d<0,則等差數(shù)列中所有正項之和最大.( )(3)在等差數(shù)列中,Sn是其前n項和,則有S2n-1=(2n-1)an.( )[答案] (1)√ (2)√ (3)√2.在項數(shù)為2n+1的等差數(shù)列中,所有奇數(shù)項的和為165,所有偶數(shù)項的和為150,則n等于( )A.9 B.10 C.11 D.12B [∵S奇S偶=n+1n,∴165150=n+1n.∴n=10.故選B項.]3.等差數(shù)列{an}中,S2=4,S4=9,則S6=________.15 [由S2,S4-S2,S6-S4成等差數(shù)列得2(S4-S2)=S2+(S6-S4)解得S6=15.]4.已知數(shù)列{an}的通項公式是an=2n-48,則Sn取得最小值時,n為________.23或24 [由an≤0即2n-48≤0得n≤24.∴所有負(fù)項的和最小,即n=23或24.]二、典例解析例8.某校新建一個報告廳,要求容納800個座位,報告廳共有20排座位,從第2排起后一排都比前一排多兩個座位. 問第1排應(yīng)安排多少個座位?分析:將第1排到第20排的座位數(shù)依次排成一列,構(gòu)成數(shù)列{an} ,設(shè)數(shù)列{an} 的前n項和為S_n。
The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut
⑦在我看來, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand,70% think space is worth exploring because we have benefited a lot from it,such as using satellites for communication and weather forecast. What’s more,with further space research,we may solve the population problem by moving to other planets one day. Also,space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1.Does the writer explain why he/she changed/wanted to change?2.Does the writer tell how the changes have improved or will improve his/her life?3.Is the text well-organised?4.Does the writer use words and expressions to show similarities and differences?5.Are there any grammar or spelling errors?6.Does the writer use correct punctuation?
? Could you offer me some kind of work here?? I don’t want your charity, I just want an honest job.? Careless: I landed in Britain by accident.Step 7:Consolidation.? Find Henry? Roderick and Oliver were I .making a bet when they saw Henry, a poor young man. ? Know Henry? About a month ago, Henry was sailing and later he found himself carried out to sea by a strong wind. Fortunately, he 2.was spotted by a ship. And it was the ship that brought him to 3.England? Offer money to Henry ? Oliver and Roderick gave Henry a letter and told him that there was money in it. They 4.persuaded him to accept it, and made him 5.promise that it wouldn't be opened until 2 o'clock.Step 8:Language pointsa large amount of: a large quantity of; a great deal ofe.g. They bought a large amount of furniture before they moved their new house.make a bet: make an arrangement to risk money, etc. on an event of which the result is doubtful.e.g. We made a bet on the result of the match.permit sb to do something: allow somebody to do somethinge.g. My mother doesn’t permit me to ride in the street after it rained.by accident: as a result of chancee.g. I only found it by accident.stare at: look at somebody or something with the eyes wide open in a fixed gaze( in astonishment, wonder, fear, etc)to be honest: to tell you the truth; to be franke.g. To be honest, I don’t think we have a chance of winning.Step7 Homework:What do you think will happen to Henry? Will the bank-note help him or get him into trouble?
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.
The theme of this unit focuses on “space exploration.” Students will learn about the training and experience needed to become an astronaut. The text is mainly about the development of space exploration. On the one hand, the text helps students to have a good understanding about the great feats humans have achieved, on the other hand, they will further understand the contributions that we Chinese have achieved, and feel confident and proud about our homeland and strengthen their love for our country. The teacher should instruct students to aim high and study harder to make great progress in the space career if possible.1. Read about the development and value of space exploration.2. Explore the mysteries of the universe and the achievements in space exploration.3. Skillfully use the vocabulary of this text to cultivate self-study ability 4.

學(xué)生在一年級上冊開始學(xué)習(xí)簡單的分類整理,初步認(rèn)識了象形統(tǒng)計圖和簡單的統(tǒng)計表。本課繼續(xù)學(xué)習(xí)統(tǒng)計,以整理隨機出現(xiàn)的簡單數(shù)據(jù)為主要內(nèi)容,并把經(jīng)過整理的數(shù)據(jù)填進(jìn)簡單的統(tǒng)計表。在統(tǒng)計過程中,讓學(xué)生學(xué)到一些比較容易的統(tǒng)計方法,滲透統(tǒng)計的思想和方法,激發(fā)培養(yǎng)學(xué)生的學(xué)習(xí)熱情和信心。三、教學(xué)目標(biāo):1、使學(xué)生體驗數(shù)據(jù)的收集、整理、描述和分析的過程,了解統(tǒng)計的意義,會用簡單的方法收集和表現(xiàn)數(shù)據(jù)。2、認(rèn)識條形統(tǒng)計圖,明確用1格表示5個單位的表現(xiàn)形式,能根據(jù)統(tǒng)計圖提出問題,并初步進(jìn)行簡單的預(yù)測。3、在學(xué)習(xí)過程中培養(yǎng)學(xué)生的實踐能力與合作意識。四、重點難點教學(xué)重點:使學(xué)生認(rèn)識條形統(tǒng)計圖,明確可以用一格表示5個單位。教學(xué)難點:引導(dǎo)學(xué)生通過合作討論找到切實可行的解決問題的方法。
一、說教材《騎鵝旅行記》是拉格洛芙為兒童寫的唯一一部長篇童話。它是根據(jù)瑞典教育部的要求,作為學(xué)校的地理教育讀物而寫的,不料后來卻成為了世界文學(xué)藝術(shù)中的珍品。因為拉格洛芙的巨大成就,1914年她被選為瑞典皇家學(xué)會會員。在瑞典,現(xiàn)在有一項最重要的兒童文學(xué)獎,就是用“尼爾斯”這個名字命名的。《尼爾斯騎鵝旅行記》寫了一個不愛學(xué)習(xí)、喜歡惡作劇的頑皮小男孩尼爾斯歷險的故事。一天,尼爾斯因為捉弄了一個小精靈而被小精靈用妖法變成一個拇指大的小人兒,后來,他騎在他家的大白鵝背上跟著一群大雁走南闖北,周游各地,一路上,他增長了許多見識,結(jié)識了許多朋友,聽了許多故事傳說,也經(jīng)歷了無數(shù)的危險。在漫長的旅途中,尼爾斯逐漸成長起來,懂得了什么是善惡,學(xué)會了同情和愛……
一、說教材 《湯姆·索亞歷險記》由“找到湯姆和貝琪”這個精彩片斷組成。片段講述的是湯姆和貝琪從迷路的山洞返回家后的故事。先是講述貝琪的媽媽撒切爾太太和湯姆的姨媽悲痛絕望的心情,以及湯姆、貝琪回來后小鎮(zhèn)歡樂的晚上。先悲后喜,充滿了喜劇氣氛。接著通過湯姆的講述,介紹他和貝琪在洞中的歷險經(jīng)過,最后講湯姆去看望伙伴哈克和貝琪,從法官口中意外地知道山洞已被封上,喬埃被困洞中。輕松、幽默而略有諷刺夸張,是作者語言的特點。浪漫有趣,有驚無險,是這部名著吸引孩子的地方。 選編本文的目的,一是通過對課文的閱讀,了解這部外國名著的內(nèi)容,關(guān)注人物的命運,把握人物的性格;二是激發(fā)學(xué)生讀整本書的興趣。 本文的教學(xué)重點是通過閱讀精彩片段,把握名著的內(nèi)容,激發(fā)學(xué)生讀外國文學(xué)作品的興趣。
四、說學(xué)法學(xué)生是學(xué)習(xí)的主體。皮亞杰認(rèn)為,在教學(xué)過程中,兒童如果不具有自己的意象活動教育就不能成功。1、整體感知,初步了解課文的大概內(nèi)容。學(xué)生先自讀課文。自學(xué)完以后,概括出文章的主要內(nèi)容。這樣,學(xué)生就會從整體上知道這篇課文講的是什么內(nèi)容。2、充分自學(xué)。人的大腦接受信息,有意注意總比無意注意有效得多。本課內(nèi)容淺顯易懂,可以充分放手讓學(xué)生自學(xué),經(jīng)過自學(xué),學(xué)生對課文有了一個大概了解,有了一番摸索的功夫,或者是略有解悟,或者是不得要領(lǐng),或者是困惑不解。一旦進(jìn)入探討階段就會全身心投入。一方面可以從容、有條不紊地發(fā)表自己的見解;另一方面略有所悟的急需得以印證和深化,不得要領(lǐng)的急需理清頭緒,困惑不解的急需弄個明白,自然都格外注意,毫不懈怠。這樣既提高了學(xué)習(xí)興趣,又留下了深刻印象,還強化了自主意識。
師:對,鎮(zhèn)定自若。(板書:鎮(zhèn)定自若)這份鎮(zhèn)定自若,別人能與他相提并論嗎?(不能)4.你還能從這段話中讀出什么來?婦女先走,船員斷后。咱們常說女士優(yōu)先,在災(zāi)難面前也做到讓婦女先走,這叫什么?生:紳士風(fēng)度。(板書:紳士風(fēng)度)5.同學(xué)們,假如你就是哈爾威船長,面對混亂的人群,你準(zhǔn)備怎樣來下達(dá)這道命令?指名學(xué)生朗讀。(師指導(dǎo):場面混亂,情況危急。)師:在災(zāi)難面前,時間就是生命。師:這是莊嚴(yán)的指揮,這是威嚴(yán)的指揮。我們一起來讀讀。師:真好,讀得好,臉部的表情也非常到位,滿臉的威嚴(yán),正因為這樣,所以課文的作者雨果是這樣評價船長的,再讀。ppt:在英倫海峽上,沒有任何一個海員能與他相提并論。(生齊讀)師:不能與他相提并論的還有他的:忠于職守、鎮(zhèn)定自若、紳士風(fēng)度。這是咱們從第一幅畫面中感受到的。
