活動(dòng)三:認(rèn)識(shí)正方體的特征,總結(jié)長(zhǎng)方體、正方體的關(guān)系(1)學(xué)生用類比法學(xué)習(xí)正方體的特征,并揭示出長(zhǎng)方體和正方體的內(nèi)在聯(lián)系,得出:正方體是特殊的長(zhǎng)方體。(2)說(shuō)說(shuō)生活中哪些物體是長(zhǎng)方體、正方體? 開(kāi)放的學(xué)習(xí)方式,以學(xué)生的自主學(xué)習(xí)為中心,讓學(xué)生通過(guò)自身的發(fā)展嘗試總結(jié),驗(yàn)證,實(shí)現(xiàn)知識(shí)的“再創(chuàng)造”。比較是認(rèn)識(shí)事物的主要方法之一,特別在幾何體教學(xué)中,運(yùn)用比較方法,加強(qiáng)形體間的聯(lián)系和區(qū)別,提高識(shí)別能力。同時(shí)滲透事物普遍聯(lián)系和發(fā)展變化的辯證唯物主義觀。聯(lián)系生活,體現(xiàn)數(shù)學(xué)來(lái)源于生活,又應(yīng)用于生活的特點(diǎn)?;顒?dòng)四:學(xué)以致用智慧屋,包含判斷題、計(jì)算題等多種題型的練習(xí),培養(yǎng)學(xué)生展開(kāi)多向思維,是學(xué)生能夠從不同角度解決問(wèn)題的基礎(chǔ)。這樣的練習(xí)題,側(cè)重于知識(shí)點(diǎn)的落實(shí),鞏固新知。
正方體的體積=棱長(zhǎng)×棱長(zhǎng)×棱長(zhǎng)用字母a表示棱長(zhǎng),V=a×a×a.也可以寫(xiě)成a3讀作a的立方.表示3個(gè)a相乘.不要誤認(rèn)為a與3相乘。寫(xiě)a3時(shí)3寫(xiě)在a的右上角要寫(xiě)小些.所以正方體的體積公式一般寫(xiě)成: V=a3(五)、鞏固練習(xí)、運(yùn)用公式練習(xí)是數(shù)學(xué)中教學(xué)鞏固新知、形成技能、發(fā)展思維、提高學(xué)生分析問(wèn)題、解決問(wèn)題能力的有效手段,為了加強(qiáng)學(xué)生的理解,使學(xué)生能正確運(yùn)用公式.我設(shè)計(jì)了多層次的練習(xí)。1、通過(guò)讓學(xué)生完成看圖求體積,這樣有助于學(xué)生理解長(zhǎng)方體正方體的體積與它的長(zhǎng)寬高的關(guān)系,記住長(zhǎng)方體的體積計(jì)算公式.2、我對(duì)安排了四個(gè)判斷題,以加深學(xué)生對(duì)a的立方的理解和運(yùn)用。3,解決實(shí)際問(wèn)題,我安排了兩道題目的是讓學(xué)生所學(xué)新知識(shí)解決生活中的一些實(shí)際問(wèn)題。
【設(shè)計(jì)意圖】學(xué)習(xí)事理說(shuō)明文,要讓學(xué)生在自主歸納的過(guò)程中,初步感知事理說(shuō)明文說(shuō)明“事理”這一基本特點(diǎn),把握事理說(shuō)明文和事物說(shuō)明文的不同之處。引導(dǎo)學(xué)生通過(guò)學(xué)習(xí)課文,對(duì)科學(xué)方法產(chǎn)生自己的體會(huì),并運(yùn)用到自己的思考中。四、總結(jié)存儲(chǔ)1.教師小結(jié)本文是一篇事理說(shuō)明文,作者把一門科學(xué)——物候?qū)W介紹得淺顯易懂,饒有趣味。全文采用邏輯順序說(shuō)明,思路清晰明了:描述物候現(xiàn)象——做出科學(xué)解釋——追究因果關(guān)系——闡述研究意義。這種從現(xiàn)象到本質(zhì)的認(rèn)識(shí)方法和行文思路值得我們學(xué)習(xí)。本文語(yǔ)言嚴(yán)謹(jǐn)而生動(dòng),兼具說(shuō)明的科學(xué)性和生動(dòng)性,是一篇極有價(jià)值的科普文,是科學(xué)家竺可楨科學(xué)精神和科學(xué)思想的具體體現(xiàn)。文章啟發(fā)我們:科學(xué)距離我們并不遙遠(yuǎn),就在我們的身邊,而想要探索它,就要有科學(xué)精神,擴(kuò)大科學(xué)知識(shí)儲(chǔ)備,掌握科學(xué)方法,勇于探索科學(xué)奧秘。
結(jié)束這節(jié)課,我心里很輕松,因?yàn)樵谝酝慕虒W(xué)中學(xué)生感覺(jué)到:說(shuō)明文很單調(diào)、枯燥不生動(dòng)。而本節(jié)課學(xué)生與我配合得非常好,原因是我利用多媒體展示的幾幅畫(huà)面,把學(xué)生的注意力都集中在所講的內(nèi)容中,并且調(diào)動(dòng)了學(xué)生學(xué)習(xí)的積極性,認(rèn)為物候現(xiàn)象就在我們的身邊,激發(fā)學(xué)生探索科學(xué)奧秘的興趣,更多地去了解大自然,認(rèn)識(shí)大自然,熱愛(ài)大自然。在初讀課文的時(shí)候,我訓(xùn)練了學(xué)生的概括能力;在分清舉例說(shuō)明的方法時(shí),讓學(xué)生明白什么是舉例子的說(shuō)明方法;在細(xì)讀課文的時(shí)候,讓學(xué)生學(xué)習(xí)生動(dòng)地有條理地說(shuō)明事物的方法,還重點(diǎn)品味第一段的生動(dòng)語(yǔ)言,在品味說(shuō)明文語(yǔ)言的準(zhǔn)確性時(shí),有日常生活中的例子導(dǎo)入,深入淺出地講解了說(shuō)明語(yǔ)言準(zhǔn)確性的兩點(diǎn)情況。
1、結(jié)合具體生活場(chǎng)景,能運(yùn)用所學(xué)的乘法口訣解決簡(jiǎn)單的實(shí)際問(wèn)題,通過(guò)圖與式的對(duì)應(yīng),進(jìn)一步理解乘法的意義。 2、能熟練運(yùn)用口訣進(jìn)行計(jì)算,提高靈活運(yùn)用口訣解決實(shí)際問(wèn)題的能力。 3、體會(huì)數(shù)學(xué)與實(shí)際生活的聯(lián)系,培養(yǎng)用數(shù)學(xué)的意識(shí),體驗(yàn)口訣在解決問(wèn)題中的作用。 運(yùn)用所學(xué)乘法解決簡(jiǎn)單的實(shí)際問(wèn)題。 結(jié)合實(shí)際情景理解乘法的意義。 1、口算: 5×2=10 6×2=12 8×5=40 2×7=14 5×9=45 3×5=15 2×6=12 2×9=18 4×2=8 2、談話導(dǎo)入:在前面的學(xué)習(xí)中,我們認(rèn)識(shí)了乘法,而且還學(xué)習(xí)了2和5的乘法口訣。這節(jié)課,老師想請(qǐng)同學(xué)們用這些跟乘法有關(guān)的知識(shí)來(lái)幫助老師一起解決生活中遇到的問(wèn)題,一起來(lái)看一看吧??鞓?lè)休息時(shí)間到了,學(xué)校的大操場(chǎng)突然熱鬧起來(lái)了,你們一定非常喜歡課件活動(dòng)吧!看,操場(chǎng)上同學(xué)們有的在玩老鷹捉小雞的游戲,有的在進(jìn)行乒乓球比賽,有的在跳繩,還有的在踢毽子……真熱鬧?。?/p>

三、教學(xué)建議第一課時(shí):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.

四、品讀揣摩詩(shī)歌情志1.讀出意境畫(huà)面。師:請(qǐng)同學(xué)們以小組為單位,齊聲朗讀詩(shī)歌,然后合作交流,探究下面問(wèn)題。(1)詩(shī)人用了哪些意象來(lái)表現(xiàn)晚春景色?詩(shī)人用了什么手法來(lái)寫(xiě)晚春景物?取得了怎樣的藝術(shù)效果?(2)詩(shī)歌一、二句寫(xiě)出了怎樣的晚春景致?請(qǐng)同學(xué)們用自己的語(yǔ)言描繪出來(lái)。(3)詩(shī)的三、四句意蘊(yùn)深刻,為歷代傳誦。請(qǐng)從修辭手法的角度對(duì)這兩句詩(shī)進(jìn)行賞析。(生齊讀后,小組交流、討論問(wèn)題,師指導(dǎo)明確)預(yù)設(shè) (1)詩(shī)人用了草樹(shù)、楊花、榆莢等意象表現(xiàn)晚春景色。一個(gè)“斗”字,運(yùn)用擬人的修辭手法,把花朵人格化,形象生動(dòng)地寫(xiě)出了晚春時(shí)節(jié)花草樹(shù)木爭(zhēng)芳斗艷的美麗景象?;ú輼?shù)木仿佛都有了情思,有了個(gè)性,成了精靈,使描繪的晚春景致生動(dòng)而有情趣。

本課由兩篇短小易懂、文辭優(yōu)美的文言文組成,針對(duì)這一特點(diǎn),本課設(shè)計(jì)分為兩課時(shí),先通過(guò)教讀《陋室銘》學(xué)習(xí)托物言志,再通過(guò)自主學(xué)習(xí)《愛(ài)蓮說(shuō)》來(lái)理解托物言志,采用先教后學(xué)的模式進(jìn)行教學(xué)。在《陋室銘》教學(xué)中,設(shè)計(jì)“朗讀”“品讀”“析讀”“聯(lián)讀”四個(gè)環(huán)節(jié),逐層深入,在讀中明特點(diǎn),讀中明志趣,讀中析寫(xiě)法,讀中悟主旨。以詩(shī)人積極的人生態(tài)度、豁達(dá)的胸襟為行文線索,從文本出發(fā),深入解讀文本,讓學(xué)生逐步理解詩(shī)人面對(duì)苦難仍能堅(jiān)守自我的人生態(tài)度和高尚情操,同時(shí)讓學(xué)生學(xué)習(xí)托物言志的手法,了解這類文章的特點(diǎn)?!稅?ài)蓮說(shuō)》采取自主學(xué)習(xí)的模式,分兩步進(jìn)行。先運(yùn)用上節(jié)課的四個(gè)環(huán)節(jié),在老師的指導(dǎo)下,進(jìn)行自主合作學(xué)習(xí)。老師給予學(xué)生自學(xué)方法,并適時(shí)引導(dǎo),讓學(xué)生逐步完成學(xué)習(xí)任務(wù),以此理解文章內(nèi)容,提高學(xué)生自主學(xué)習(xí)文言文的能力;再采用競(jìng)賽的方式展示學(xué)習(xí)成果,以幾個(gè)不同形式的比賽,來(lái)激發(fā)學(xué)生的學(xué)習(xí)興趣,讓學(xué)生在競(jìng)賽中夯實(shí)文言文的基礎(chǔ)知識(shí),在競(jìng)賽中加深對(duì)文章的理解,學(xué)會(huì)探究。本課整個(gè)教學(xué)設(shè)計(jì)思路清晰,教學(xué)方法可操作性強(qiáng)。
三、暢意表達(dá),理解英雄1.暢意表達(dá)。師:通過(guò)學(xué)習(xí)課文,你們明白了楊利偉為什么被稱為“航天英雄”嗎?請(qǐng)同學(xué)們大膽表達(dá)自己的想法。(生自由交流回答)預(yù)設(shè) 楊利偉是中國(guó)人民解放軍航天員大隊(duì)的首飛航天員,圓滿完成了中國(guó)的第一次載人航天飛行任務(wù)。在充滿不可預(yù)料的各種危險(xiǎn)和意外的情況下,楊利偉為了國(guó)家、民族的利益奮不顧身,他具有不怕?tīng)奚?、敢于犧牲的大無(wú)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(guó)捐軀者才能成為英雄呢?請(qǐng)同學(xué)們四人一小組討論一下,然后說(shuō)說(shuō)你們組的意見(jiàn)。(生小組內(nèi)交流討論后,推薦代表在全班交流,師指導(dǎo)明確)預(yù)設(shè) 不是的。凡是為了國(guó)家、民族的利益而不顧個(gè)人安危,并為此奉獻(xiàn)出自己的智慧和力量的人,都應(yīng)該給予英雄的榮譽(yù)。楊利偉在中國(guó)的第一次載人航天飛行中,遇到許多突發(fā)事件,危難考驗(yàn)不時(shí)出現(xiàn),如果沒(méi)有大無(wú)畏的精神,沒(méi)有為國(guó)家、民族做貢獻(xiàn)的意識(shí),是不可能臨危不懼、堅(jiān)持到底的。
