一、教材分析長(zhǎng)方體和正方體的表面積是人教版教材五年級(jí)下冊(cè)第三單元第二章節(jié)的內(nèi)容。本節(jié)課的地位和作用:這部分內(nèi)容是在學(xué)生學(xué)習(xí)了長(zhǎng)方體和正方體的認(rèn)識(shí)以及掌握了長(zhǎng)方形和正方形面積的計(jì)算方法的基礎(chǔ)上進(jìn)行教學(xué)。教材中各年級(jí)涉及到的內(nèi)容如下:長(zhǎng)方體和正方體的表面積這部分內(nèi)容,是在學(xué)生認(rèn)識(shí)并掌握了長(zhǎng)方體和正方體特征的基礎(chǔ)上教學(xué)的。教材為了使學(xué)生更好地建立表面積的概念,加強(qiáng)了動(dòng)手操作,讓每個(gè)學(xué)生拿一個(gè)長(zhǎng)方體或正方體紙盒,沿著棱剪開,再展開,觀察展開后的形狀。并分別用“上”“下”“前”“后”“左”“右”標(biāo)明6個(gè)面。這樣,可以使學(xué)生把展開后每個(gè)面與展開前這個(gè)面的位置聯(lián)系起來,更清楚地看出長(zhǎng)方體相對(duì)的面的面積相等,以及每個(gè)面的長(zhǎng)和寬與長(zhǎng)方體的長(zhǎng)、寬、高之間的關(guān)系,既讓學(xué)生明確了表面積的含義,又為下面學(xué)習(xí)計(jì)算長(zhǎng)方體和正方體的表面積做好了準(zhǔn)備。
3.說教學(xué)重、難點(diǎn)依據(jù)數(shù)學(xué)課程標(biāo)準(zhǔn),及對(duì)教材的認(rèn)識(shí),我確定了本節(jié)課的重點(diǎn)和難點(diǎn)。教學(xué)重點(diǎn):掌握長(zhǎng)方體和正方體的特征。教學(xué)難點(diǎn):建立“立體圖形”的空間概念,了解長(zhǎng)方體、正方體的關(guān)系。二、說教法根據(jù)幾何知識(shí)的教學(xué)特點(diǎn)、本節(jié)教學(xué)內(nèi)容以及小學(xué)生空間觀念薄弱的特點(diǎn),我將采用以下教學(xué)方法。直觀演示法:利用圖片等手段進(jìn)行直觀演示,激發(fā)學(xué)生的學(xué)習(xí)興趣;觀察發(fā)現(xiàn)法:通過讓學(xué)生觀察長(zhǎng)方體、正方體的一些實(shí)物發(fā)現(xiàn)新知,培養(yǎng)學(xué)生的觀察概括能力;合作探究法:引導(dǎo)學(xué)生通過自主研究、合作討論等活動(dòng)形式來獲取知識(shí)。同時(shí)運(yùn)用多媒體輔助教學(xué),使學(xué)生的觀察能力、抽象概括能力逐步提高。三、說學(xué)法為了使學(xué)生較好地掌握長(zhǎng)方體和正方體的特征,并逐步形成空間觀念,除了讓學(xué)生通過觀察來認(rèn)識(shí)長(zhǎng)方體和正方體的特征以外,在觀察實(shí)物的基礎(chǔ)上,通過動(dòng)手操作,看一看,摸一摸,數(shù)一數(shù),量一量,做一做來學(xué)習(xí)新知,同時(shí)以此來激發(fā)學(xué)生的學(xué)習(xí)興趣,調(diào)動(dòng)學(xué)生的積極性。
本單元前幾課時(shí)已經(jīng)認(rèn)識(shí)了長(zhǎng)方體和正方體的特征,學(xué)習(xí)了表面積的計(jì)算。這節(jié)課要在此基礎(chǔ)上掌握體積的概念和常用的體積單位,學(xué)會(huì)長(zhǎng)方體和正方體的體積計(jì)算,掌握公式的意義和用法。這是下一步學(xué)習(xí)體積單位進(jìn)率的基礎(chǔ),更是以后學(xué)習(xí)容積的基礎(chǔ)。因此,長(zhǎng)方體和正方體的體積計(jì)算必須掌握熟練。教學(xué)目標(biāo)1、結(jié)合具體自作,引導(dǎo)學(xué)生探索并掌握長(zhǎng)方體、正方體體積的計(jì)算公式,并能熟練地運(yùn)用公式解決一些實(shí)際問題。 2、通過探索活動(dòng),培養(yǎng)學(xué)生的分析、概括能力,發(fā)展學(xué)生的空間觀念。 3、培養(yǎng)學(xué)生數(shù)學(xué)的應(yīng)用意識(shí)。 重點(diǎn):掌握長(zhǎng)方體、正方體體積的計(jì)算方法,并運(yùn)用公式解決實(shí)際問題。 難點(diǎn):理解體積公式的意義。
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)說說生活中哪些物體是長(zhǎng)方體、正方體? 開放的學(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)生展開多向思維,是學(xué)生能夠從不同角度解決問題的基礎(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。
4、認(rèn)識(shí)長(zhǎng)方體的立體圖。師:(出示課件長(zhǎng)方體)你最多能看到這個(gè)長(zhǎng)方體的幾個(gè)面?你看到了哪三個(gè)面?哪三個(gè)面看不到?(上面、前面、右面)師:我們把所看到的這個(gè)長(zhǎng)方體根據(jù)透視原理畫下來就是這樣的。(媒體演示) 這就是長(zhǎng)方體的立體圖形。師:大家會(huì)認(rèn)了嗎?試一試。師小結(jié):以后,我們要判斷一個(gè)物體是不是長(zhǎng)方體,要根據(jù)長(zhǎng)方體的特征去分析。5、畫長(zhǎng)方體師:同學(xué)們都學(xué)得非常認(rèn)真知道了長(zhǎng)方體的特征,那么大家會(huì)畫長(zhǎng)方體嗎?畫長(zhǎng)方體步驟:1、畫一個(gè)平行四邊形。2、畫出長(zhǎng)方體的高。3、連線。6、 教學(xué)長(zhǎng)方體的長(zhǎng)、寬、高。 (1)、師:同學(xué)們剛畫出了長(zhǎng)方體,那么長(zhǎng)方體的長(zhǎng)、寬、高有什么特點(diǎn)?師課件展示后,學(xué)生匯報(bào)。(2)、大家想不想親手制作一個(gè)長(zhǎng)方體的框架呢?把你思考的結(jié)果和大家分享分享。生匯報(bào)。
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a3時(shí)3寫在a的右上角要寫小些.所以正方體的體積公式一般寫成: 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)生分析問題、解決問題能力的有效手段,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)際問題。
Step 3 (3b)First, tell the students when we talk about our future plans, we often use: I’m+verb+ing When we talk about what we must do, we use have to. Ask the students to fill in the blanks in 3b. The answers are: shopping, go to see, a test, I’m going, my family. Step 4 (3c)Let the students write an e-mail message to a friend. Say why you can’t visit next. Before the exercise, ask the students to give some possible answers and write them on the blackboard. So the students will feel easy to finish the writing exercise. After they finish it, Let them to correct it in groups first. Each group chooses theirs best one to read in front of the whole class. Step 5 ( planning a party )First read the conversation in the box together. Then ask the students to turn to page 88.Write down everything you have to do next week. Write in all the things you have to do . Ask the students to look at the list. Ask them “What day are you free?” This is when you can have your party. Step 6 (Self check 1 )Let the students to fill in the blanks with the words given. Change the forms of the words if possible. Then make their own sentences. The answers are: visit, playing, have to, study, comeStep 7 (Self check 2)Imagine you are Marie. Read the information and look at your schedule. Write replies to the invitation.
Step Ⅶ Role play ( Work on 1b)1. First ask two students to read the dialogue to the class.Sa: How do you get to school?Sb: Well, I ride my bike to the subway station. Then I take the subway.2. Now work with a partner.Suppose you use two kinds of transportation to get to school \Hangzhou\Beijing... (bus, train, subway, walking, bike, etc.) Tell how you get there. You may use the phrases in 1a.3. Then ask different pairs of students to present their conversations to the class.Step ⅧListening1. Work on 2a(1) First ask students to read the list of information that Thomas wants to know.…where Nina lives.…h(huán)ow far from school she lives.…h(huán)ow long it takes to get to school.…h(huán)ow she gets to school.…what she thinks of the transportation.(2) Tell students what transportation and bus stop mean.bus stop 汽車站 transportation n. 運(yùn)送;運(yùn)輸Then tell students we'll hear a recording. Please put a checkmark in front of each thing that Thomas wants to know.(3) Now play the recording for students.( Have students pay attention to the sample answer.) (4) Then correct the answers.
教學(xué)重點(diǎn)和難點(diǎn):運(yùn)用所掌握的語言描述,比較不同地點(diǎn)的特點(diǎn)。在練習(xí)中學(xué)習(xí)掌握英語比較級(jí)和最高級(jí)的用法。課前準(zhǔn)備分配小組,每組五至六人。通過上網(wǎng)或翻閱報(bào)刊雜志等方法,確定旅游線路,做出基本的旅游計(jì)劃。教學(xué)設(shè)計(jì):本節(jié)課流程圖 學(xué)法指導(dǎo):1.由于這是一堂新課,在教學(xué)中應(yīng)注意面向全體,發(fā)揮學(xué)生的主體性,引導(dǎo)學(xué)生積極參與,激發(fā)學(xué)生的求知欲和學(xué)習(xí)積極性,指導(dǎo)學(xué)生積極思維,主動(dòng)獲取知識(shí),養(yǎng)成良好的學(xué)習(xí)方法。逐步學(xué)會(huì)獨(dú)立解決問題??傊M可能調(diào)動(dòng)學(xué)生的非智力因素促進(jìn)智力因素的發(fā)展。教法選擇:1.電化教學(xué)法2.課堂討論法3.任務(wù)型教學(xué)法采用這些方法的目的是為了充分調(diào)動(dòng)學(xué)生的學(xué)習(xí)積極性,使學(xué)生變被動(dòng)學(xué)習(xí)為主動(dòng)學(xué)習(xí)。通過電腦形象的演示,加強(qiáng)印象,提高興趣,突破難點(diǎn),提高教學(xué)效率,進(jìn)而增大教學(xué)的容量和信息量。充分體現(xiàn)教師為主導(dǎo),學(xué)生為主體的教學(xué)原則。
She shouldn’t go to the party tonight.Step7. TaskT: You know, there are lots of problems in our life. If you are a doctor, please tell us how to solve the problem. I will divide you into 9 groups. Please work in groups. And then choose one of you to report your ideas.The following are the problems:I have a toothache.I am hungry. I have a sore throat.I am stressed out.

You shouldn’t wash your face with cold water.You shouldn’t sleep late.You shouldn’t swim.…..T encourages the students to give advice as much as possible.Homework:1. Chose one of the problems, and write down your advice2. Copy the new words這一步是用于熱身的,同時(shí)也可以讓他們復(fù)習(xí)一部分的表示人體部位的單詞,擴(kuò)充知識(shí).學(xué)習(xí)語言的過程也是一個(gè)不斷積累的過程,復(fù)習(xí)舊知識(shí),增添新知識(shí).通過小游戲,強(qiáng)化學(xué)生對(duì)Does she/he have…這個(gè)句子的運(yùn)用能力.通過復(fù)習(xí),自然的引到下面新知識(shí)的學(xué)習(xí)。充分利用表格,由句子到對(duì)話,再到文章,讓學(xué)生循序漸進(jìn). 提高學(xué)生的綜合語言運(yùn)用能力,運(yùn)用以前學(xué)過的知識(shí)來解決身邊的問題.Period 5 (Section B 3a—3c, selfcheck)教學(xué)內(nèi)容與分析:
1. First, ... then, ... next, ... finally, ...首先,……然后,……接著,……最后,……這是英語中表達(dá)做某事的步驟的一種說法。如果步驟較多,還可以說:first-next-after that-later on-finally/at last通常你會(huì)聽到說英語國家的人在說 first, next, then, finally 和后面的內(nèi)容時(shí),他們會(huì)做一些停頓。這樣就能提前告訴聽者接下來講的是一系列的步驟。這一點(diǎn)在朗讀和聽力中應(yīng)特別注意。2. how many, how much均為疑問詞,同是“多少”,但用法不同。請(qǐng)看:how many修飾可數(shù)名詞復(fù)數(shù),how much修飾不可數(shù)名詞。但在用法上,同學(xué)們常犯如下錯(cuò)誤:1) [誤] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容詞,常修飾名詞作定語,故后面跟名詞。2) [誤]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修飾不可數(shù)名詞時(shí),謂語動(dòng)詞用單數(shù)。how many與how much的區(qū)別可簡(jiǎn)記為:前how many:?jiǎn)枴岸嗌佟?,?fù)數(shù)名詞后面跑;how much問“多少”,不可數(shù)名詞單數(shù)好。前者答語用基數(shù)詞,后者答語用數(shù)量關(guān)系。
“Go for it!” is based on “Task-Based Language Teaching”. It adheres to “The authenticity principle”, “The form-function principle”, “The task dependency principle” and “The principle of learning by doing”. These principles all accord with the demands of curriculum focus.In and of Grade Seven (II), “Go for it!”, students have learned “The Simple Past Tense”. And it appears again in of Grade Eight (I). teaches students more about how to talk about events in the past. In addition, it gives affirmative and negative statements in the past tense, such as the sentence patterns “Did you see …?” “Were there …?” “Did you go …?” As the first part of Unit 8, Section A opens with a picture presenting the last school trip in the aquarium and continues with several step-by-step practice activities, which are all good for students to master “The Simple Past Tense”. Doing well in Section A will help students integrate the new target language with that in Section B. Thus, they can describe the events in the past freely and foster their own ability of reflecting and practicing. II. Teaching ObjectivesTeaching objective is the beginning and aim of teaching activities. According to the overall goal of the English elementary course--- improve students' synthetic ability of language application, which should be based on the development of students’ “Language knowledge”, “Language skills”, “Character building”, “Learning strategies” and “Cross-cultural awareness”. The teaching objectives are described as follows(I). Knowledge objectivesi. Master the simple past tense of regular and irregular verbsii.

二、新授環(huán)節(jié)新授環(huán)節(jié)是本堂課的重點(diǎn),我主要分為6步來突破語言點(diǎn),步步為營(yíng),環(huán)環(huán)相扣,達(dá)到既定目標(biāo)。1、首先我用touch and guess游戲來呈現(xiàn)新授單詞present,通過CAI展示各種生日禮物,如衣服,書本,玩具等讓學(xué)生操練單詞:Books can be a present等,操練時(shí)做到詞不離句。2、接著我借助多媒體讓學(xué)生說說自己想要的禮物I want a_____,同時(shí)我將實(shí)現(xiàn)準(zhǔn)備的實(shí)物和圖片作為禮物贈(zèng)送給他們,新授句子Here’s a present for you,激發(fā)學(xué)生開口說的興趣,又為接下來的操練提供了資源。我利用剛才分發(fā)的禮物采用游戲 “I’m a little bee”, (S1:I’m a little bee. Today is my birthday. S3:Here’a present for you。)四人小組合作操練這個(gè)句型。既避免了操練的機(jī)械性又調(diào)動(dòng)了學(xué)生的積極性,而且提供了讓每個(gè)學(xué)生開口說的機(jī)會(huì),關(guān)注學(xué)生個(gè)體的發(fā)展。3、當(dāng)學(xué)生Act完后,我對(duì)一學(xué)生說:Oh, little bee, what’s your present? Open it and see。讓學(xué)生打開禮物呈現(xiàn)實(shí)物生日賀卡教學(xué)詞匯birthday card。既做到了呈現(xiàn)自然,又滲透西方文化知識(shí),培養(yǎng)學(xué)生跨文化交際意識(shí)。
二.多維活動(dòng)體現(xiàn)教師角色的變換 師生是教學(xué)中的兩個(gè)主體,教師是主導(dǎo),學(xué)生是主體。教師角色要適時(shí)變換,才能充分發(fā)揮學(xué)生的主體作用,課堂教學(xué)才會(huì)成為師生間共同參與的多維活動(dòng)。在本堂課的教學(xué)中,首先,教師是示范者,通過各種手段直觀呈現(xiàn)材料,“引發(fā)”學(xué)生思維,“啟動(dòng)”學(xué)生探索。在呈現(xiàn)新知前利用課件創(chuàng)設(shè)Field Trips情景,再通過與學(xué)生交談引出本課功能句型,并示范如何用英語去詢問。其次,教師是啟發(fā)者,引導(dǎo)學(xué)生去發(fā)現(xiàn)去學(xué)習(xí)。在引出本課功能句型后,老師沒有急于告訴學(xué)生如何回答,而是引導(dǎo)學(xué)生,讓他們自己說出完整的答句Yes,he/she is.或No, he /she isn't.。在任務(wù)進(jìn)行的過程中,學(xué)生既說又唱,既演又想,手、腦、口、耳、眼、肢,體并用;靜態(tài)、動(dòng)態(tài)結(jié)合。在輕松、愉快的活動(dòng)中真正用感官和心靈去體驗(yàn)英語語言及其運(yùn)用。最后,在完成任務(wù)的過程中,教師還是助手和觀眾,引導(dǎo)和幫助學(xué)生順利地完成調(diào)查任務(wù),進(jìn)一步鞏固拓展所習(xí)得的語言。讓他們體會(huì)到成功的喜悅,從而樹立學(xué)好英語的信心。
四、拓展提高,評(píng)價(jià)促學(xué)1、欣賞故事。在學(xué)習(xí)完所有內(nèi)容后,老師請(qǐng)學(xué)生繼續(xù)聽、看和試著說出這個(gè)童話故事的一部分,然后通過拜訪幾個(gè)動(dòng)物的家庭,利用我們眼睛看到的事物,我舉例示范了一個(gè)對(duì)話,并根據(jù)聽到的內(nèi)容將所缺少的單詞填寫進(jìn)去。在原來聽、說、讀的基礎(chǔ)上,增加了寫的環(huán)節(jié),真正完成了單詞的四會(huì)要求。2、童話表演。這個(gè)童話故事將所有的內(nèi)容綜合在一起,是單詞與句型的綜合運(yùn)用。在學(xué)生聽說讀寫的訓(xùn)練過程之后,兩人小組的表演培養(yǎng)了學(xué)生的合作學(xué)習(xí)能力,讓學(xué)生們通過師生、生生、小組等不同的合作方式,學(xué)會(huì)傾聽,學(xué)會(huì)評(píng)價(jià)。3、中心升華。最后,我利用小鳥的眼睛,我們一起欣賞了大千世界各種美麗的事物,讓學(xué)生學(xué)習(xí)之余,能夠有所減壓和感受,連青蛙都喜歡上整個(gè)世界,跳出了小井,感受整個(gè)世界的美好。五、課堂小結(jié),作業(yè)布置(1) 抄寫所學(xué)的四會(huì)單詞。(2)將童話劇表演給父母看。這一環(huán)節(jié)培養(yǎng)了學(xué)生語言的運(yùn)用能力,體驗(yàn)學(xué)習(xí)英語的成功帶來的喜悅,達(dá)到學(xué)以致用的目的。
四、教學(xué)過程:為了實(shí)現(xiàn)以上教學(xué)目標(biāo),我從以下四個(gè)環(huán)節(jié)設(shè)計(jì)本課時(shí)的教學(xué)過程。(一)熱身、復(fù)習(xí)在本環(huán)節(jié)我選用歌曲“What’s your favourite season?”作為新課的熱身,使學(xué)生在輕松愉快的環(huán)境下接受英語的熏陶。通過Free talk環(huán)節(jié)談?wù)摚篐ow many seasons in a year? What are they? 對(duì)學(xué)生所掌握的知識(shí)進(jìn)行滾動(dòng)復(fù)習(xí),同時(shí)又為新課做鋪墊。(二)新知呈現(xiàn)為了更好地突出教學(xué)重點(diǎn),分散難點(diǎn),在這一環(huán)節(jié)將利用多媒體設(shè)置不同的任務(wù)來完成新知呈現(xiàn)。1、任務(wù)一:四季的色彩和景色課件展示春夏秋冬四季的圖片。問學(xué)生:What colour is the spring/summer/fall/ winter?在學(xué)生回答后再向?qū)W生提問:What’s your favourite season? Why?請(qǐng)學(xué)生根據(jù)四季的“顏色”來選擇自己喜歡的季節(jié),引導(dǎo)學(xué)生用句型“Because I see…”來說出自己喜歡的理由。通過“I see…”這個(gè)角度,培養(yǎng)學(xué)生善于觀察大自然,熱愛大自然的情感。2、任務(wù)二:四季的天氣和著裝提問學(xué)生“What’s the weather like in spring/summer/fall/winter?”讓學(xué)生通過談?wù)摗疤鞖夂椭b”來選擇自己喜歡的季節(jié),并能從生活實(shí)際出發(fā),利用句型“Because I wear…”陳述喜歡的理由,進(jìn)一步培養(yǎng)學(xué)生的思維能力。
