二、說教學(xué)目標(biāo)1.能有感情朗讀詩文,背誦詩文。2.能借助圖片,發(fā)揮想象,走進(jìn)詩境,從而體會詩人熱愛祖國河山的感情。三、說教學(xué)重難點1.朗讀古詩,讀出感情,讀出韻味。(重點)2.欣賞古詩意境,體會詩人的感情,培養(yǎng)熱愛祖國河山的思想感情。(難點)四、說教法學(xué)法科學(xué)合理的教學(xué)方法能使教學(xué)效果事半功倍,達(dá)到教與學(xué)的和諧完美統(tǒng)一?;诖?,我準(zhǔn)備采用的教法是情境教學(xué)法并以多媒體手段輔助教學(xué),力求達(dá)到以讀代講、讀中促思、讀中悟情的效果。? 三年級的學(xué)生對于韻文的學(xué)習(xí)有一定難度,但他們有了一定的學(xué)詩經(jīng)驗,會對本詩的學(xué)習(xí)、理解起到極大的推動作用。本節(jié)課將以讀代講引導(dǎo)學(xué)生用朗讀感悟法,想象感悟法,穿插自主合作學(xué)習(xí)法,力求在讀中受到情感熏陶,在品味語言中積累語言,在內(nèi)容學(xué)習(xí)中掌握方法。
一、說教材:《六月二十七日望湖樓醉書》是國家統(tǒng)編教材小學(xué)語文六年級上冊第一單元的一首文質(zhì)兼美、情景交融的古詩,作者蘇軾以精煉的文字展現(xiàn)了一場急來驟去的西湖雨。文章既有寫景的語句,又隱藏人物內(nèi)心活動,是一篇指導(dǎo)學(xué)生學(xué)習(xí)古詩很好的范例。1.教材地位:課標(biāo)要求:閱讀詩歌,大體把握詩意,想象詩歌描繪的情景,體會作品的感情。誦讀優(yōu)秀詩文,注意通過語調(diào)、韻律、節(jié)奏等品味作品內(nèi)容和情感。以《六月二十七日望湖樓醉書》為例的古詩學(xué)習(xí)課,旨在讓學(xué)生抓住詩中關(guān)鍵的字詞感受詩歌的內(nèi)容和情感。同時,以課標(biāo)為準(zhǔn)繩,把教材與學(xué)生生活聯(lián)系起來,將同類型的古詩進(jìn)行整合。在讀懂《六月二十七日望湖樓醉書》的基礎(chǔ)上,對同是寫雨的古詩進(jìn)行同類拓展,對于學(xué)生誦讀積累優(yōu)秀詩文具有一定指導(dǎo)作用。
一、說教材分析《書湖陰先生壁》是六年級上冊語文第六單元的內(nèi)容,是宋代詩人王安石的作品。這首詩是題寫在湖陰先生家墻壁上的。前兩行寫他家的環(huán)境,潔凈清幽,暗示主人生活情趣的高雅;后兩行轉(zhuǎn)到院外,寫山水對湖陰先生的深情,暗用“護(hù)田”與“排闥”兩個典故,把山水化成了具有生命感情的形象,山水主動與人相親,正是表現(xiàn)人的高潔。詩中雖然沒有正面寫人,但寫山水就是寫人,景與人處處照應(yīng),句句關(guān)合,融化無痕。詩人用典十分精妙,讀者不知典故內(nèi)容,并不妨礙對詩歌大意的理解;而詩歌的深意妙趣,則需要明白典故的出處才能更深刻地體會。二、說教學(xué)目標(biāo)1、正確、流利、有感情地朗誦古詩;2、能借助注釋及相關(guān)資料,理解詩句所描繪的情境,感悟詩人豐富的想象力;3、學(xué)習(xí)擬人與描寫巧妙結(jié)合的表達(dá)方法,體會詩人退居田園后愉悅的心境。3、知詩人,解詩題;明詩意,感情讀;悟詩情,感情背。
(2)理解詩意。(告訴方法,引導(dǎo)自學(xué))①同學(xué)們通過詩題就知道了詩的內(nèi)容了,太棒了,誰能告訴我詩人會看到什么樣的景象?(指名回答,學(xué)生互相補(bǔ)充糾正)明確:瑟瑟(形容未受到殘陽照射的江水呈現(xiàn)的青綠色)、可憐(可愛)、真珠(珍珠)②同學(xué)們描述的都很漂亮,我們在翻譯詩句意思的時候一定要跟詩句結(jié)合起來,不能增加詩中沒有的內(nèi)容,也不能刪減詩中原有的內(nèi)容。在這個基礎(chǔ)上,誰能再說說詩句的意思?(指名答,課件展示) ③白居易在詩中這么描繪,是不是真實的呢?有同學(xué)說真實,因為真的見到過這樣的景象,也有同學(xué)表示不理解,很棒,學(xué)貴質(zhì)疑,我們來看看這些圖片,說說我們的老朋友寫的準(zhǔn)不準(zhǔn)確?(課件展示) (3)分析詩歌。(引導(dǎo)提示) ①引導(dǎo)背誦。合上課本,我們現(xiàn)在跟著白居易一起,我們在傍晚的時候來到了江邊,首先看到了什么?用詩句回答(一道殘陽鋪水中),我們往下看江面,江面的景象是什么樣的?(半江瑟瑟半江紅),這樣的場面讓我們留戀了一會,太陽下去了,夜晚到來了,我們欣賞著風(fēng)光,覺得這夜晚怎么樣?(可憐九月初三夜),可愛的夜晚,露水晶瑩像珍珠,月兒彎彎像弓,詩人脫口而出(露似真珠月似弓)。
一、說教材:對于《題西林壁》這篇課文,我是這樣解讀的:《題西林壁》是一首哲理詩,作者通過描寫游覽廬山的經(jīng)歷,總結(jié)出觀察問題應(yīng)客觀全面,如果主觀片面,就得不出正確的結(jié)論的道理。二、說學(xué)情:對于學(xué)生的情況,我是這樣認(rèn)為的:四年級的學(xué)生,他們的思維以具象思維為主,因此他們對于文中描寫的景物有自己的感觸。但是他們抽象思維能力較弱,而本詩又是一首哲理詩,學(xué)生在理解上有一定的難度,這就需要教師加以引導(dǎo)。除此之外,學(xué)生的有意注意力和穩(wěn)定性還是較差的,所以教師在教學(xué)過程中要運(yùn)用多媒體、圖片等來增強(qiáng)教學(xué)的直觀性、形象性,以吸引學(xué)生的注意力。
一、說教材:《西江月夜行黃沙道中》這首詞是宋代詞人辛棄疾貶官閑居江西上饒時的一篇名作。它以自然樸素的語言,給我們展現(xiàn)了一幅鮮明逼真的田野風(fēng)光圖。我對這節(jié)課的定位是:以誦讀來“幫助”解析。二、說教學(xué)目標(biāo):本課的教學(xué)目標(biāo)概括起來為三個字,即:讀、品、悟從教學(xué)目標(biāo)的三維目標(biāo)形式來說,即為:1、正確、流利、有感情地朗讀課文。背誦課文。2、通過語言文字,融入自己豐富的想象,感悟這首詞所描繪的意境。3、通過朗讀,感受詞中所表現(xiàn)的自然美,感悟作者熱愛大自然,企盼豐年的思想感情。三、說重難點:感受詞中所表現(xiàn)的自然美,想象詞句所描繪的畫面,體會詞中蘊(yùn)含的詩人的情懷。四、說教法、學(xué)法:新課程標(biāo)準(zhǔn)提出對六年級學(xué)習(xí)詩詞的要求:“通過詩文的聲調(diào)、節(jié)奏、想象等來體現(xiàn)作品的內(nèi)容和感情?!笨紤]到本年級學(xué)生的學(xué)習(xí)能力,在本節(jié)課教學(xué)中,我把“讀”貫穿于整個課堂。
各位老師上午(下午)好!今天我說課的內(nèi)容是《宿建德江》。我將從教材分析、學(xué)情分析、教學(xué)方法、教學(xué)過程、教學(xué)反思等方面作具體的闡述。一、教材分析《宿建德江》選自國家統(tǒng)編教材小學(xué)語文六年級上冊第一單元,是一首刻畫秋江暮色的寫景作品?!俺睢笔侨姷脑娧?,全詩圍繞“愁”字顯示著作者高超的藝術(shù)構(gòu)思,屬于山水田園詩,詩人寄情山水,在山水風(fēng)光的描寫中抒發(fā)自己或閑適或愁苦的情懷,這正是山水田園詩“一切景語皆情語”的主要特點。有趣的是這首詩的景語中的“明月”,寄予的情感是:落第而歸,仕途無望,暮靄曠野使詩人舊愁更添新愁。據(jù)此,我制定了以下三個教學(xué)目標(biāo):(一)知識目標(biāo):認(rèn)識本課生字,能正確、流利、有感情地朗讀課文,背誦課文。

五、教學(xué)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?

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(dá)個人喜好,以及句式why do you like…? Because…。這也是本單元的教學(xué)重點。通過本單元的學(xué)習(xí),學(xué)生應(yīng)能較流利地運(yùn)用所學(xué)詞匯和句型描述動物,表達(dá)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?

(6)交流。6的乘法口訣一共有幾句?口訣中的第一個數(shù)與算式中的第二個因數(shù)相同,表示什么?口訣中的第二個數(shù)與算式的第一個因數(shù)相同,表示什么?相鄰兩句口訣的積相差幾?哪幾句難記一些?你用什么方法記呢?怎樣記住"三六十八"、"四六二十四"兩句口訣?教師在學(xué)生發(fā)言的基礎(chǔ)上鼓勵學(xué)生大膽說、想出不同記口訣的方法。(7)應(yīng)用"做一做"第1題(學(xué)生半獨(dú)立完成):①用6根小棒擺1個六邊形;②擺2個六邊形要用多少根小棒?你是怎樣想的?(想口訣"二六十二"。)③運(yùn)用所學(xué)的口訣口答擺4個、6個、3個、5個六邊形所需要向小棒數(shù)。"做一做"第2題(獨(dú)立完成):①將第2題改為填空題,在圓圈內(nèi)填寫正確的積;②口答得數(shù),并說一說所用口訣。
三、利用乘法口訣進(jìn)行計算1.復(fù)習(xí)口訣的含義。任意挑出一句乘法口訣(兩個因數(shù)不同的),讓學(xué)生說說它表示什么意思。如"七八五十六",使學(xué)生知道它既表示8個7相加是56,又表示?個8相加是56。2.以游戲的方式開展用口訣進(jìn)行計算的活動。(1)已知兩個因數(shù)求積的游戲。方法是:請一位學(xué)生隨意說出一個兩位數(shù),另一位學(xué)生則將這個兩位數(shù)的十位數(shù)字與個位數(shù)字相乘,并算出結(jié)果,如果結(jié)果又是一個兩位數(shù),再將這個兩位數(shù)的十位數(shù)字和個位數(shù)字相乘,直至結(jié)果是一位數(shù)或零。如,一位學(xué)生說:"79",另一位學(xué)生則口算:7X9=636X3=181X8=8;一位學(xué)生說:"58":另一位學(xué)生口算:5X8=404X0=0(告訴學(xué)生0和一個數(shù)相乘得零)一位學(xué)生報了3個數(shù)以后,互換角色進(jìn)行。(2)已知積求兩個因數(shù)的游戲。
