二、說教法在本課的教學中我力求改變過去重知識、輕能力,重結(jié)果、輕過程,重教法、輕學法的狀況。樹立以“以學生發(fā)展為本”、“以學定教”、“教為學服務(wù)”的思想。本課的教學方法有創(chuàng)設(shè)情境法、引導探究法、類比遷移法、歸納總結(jié)法、組織練習法等。三、說學法我們常說:“現(xiàn)代的文盲不是不識字的人,而是沒有掌握學習方法的人”,因而我們要特別重視學生學習方法的培養(yǎng)和指導。本課學生的學習方法主要有:自主發(fā)現(xiàn)法、合作探究法、類比遷移法、歸納總結(jié)法、感知體驗法等。四、說教學程序課標指出教學應(yīng)遵循學生學習數(shù)學的心理規(guī)律,強調(diào)從學生已有生活經(jīng)驗出發(fā),將數(shù)學活動置身于實施的生活背景之中,為他們提供觀察操作、實現(xiàn)的機會。根據(jù)本節(jié)課的教學內(nèi)容我設(shè)置了如下四大環(huán)節(jié):(一)復習舊知、引入新課。

我說課的內(nèi)容是小學數(shù)學二年級下冊《1000以內(nèi)數(shù)的認識》,本節(jié)課的教學時建立在學生學習過百以內(nèi)數(shù)的認識基礎(chǔ)之上的,是學生對100以內(nèi)數(shù)的認識的延伸和擴展,同時,它有著一個非常重要的地位,就是要為學習10000以內(nèi)數(shù)的認識做好鋪墊,因為,1000或10000都是比較大的數(shù),在學生的認識還很有限的基礎(chǔ)上,如何讓學生能盡快的建立起大數(shù)的概念和意識,在這里格外重要,對于這一部分內(nèi)容,《小學數(shù)學課程標準》中是這樣闡述的:能認、讀、寫萬以內(nèi)的數(shù),會用數(shù)表示物體的個數(shù)或事物的順序和位置,能說出各數(shù)位的名稱,識別各數(shù)位的數(shù)字的意義;結(jié)合現(xiàn)實素材感受大數(shù)的意義,并能進行結(jié)算。根據(jù)這一闡述,我把本課時的教學目標定義以下幾點:1、學習1000以內(nèi)的數(shù),體驗數(shù)的產(chǎn)生和作用。2、會數(shù)1000以內(nèi)的數(shù),認識計數(shù)單位“千”,體會十進關(guān)系。3、讓學生經(jīng)歷觀察、猜想、操作等數(shù)學活動過程,結(jié)合現(xiàn)實材料感受大數(shù)的意義,逐漸發(fā)展學生的數(shù)感。

學生自由編題后,教師出示:蹺蹺板樂園有3個蹺蹺板,每個蹺蹺上有4人在玩,還有7人在旁邊看。蹺蹺板樂園里一共有多少人?(2)全班讀題后提問,題目的已知條件和問題是什么?根據(jù)題目的已知條件,能不能一步就算出蹺蹺板樂園里一共有多少人?(不能)那我們要求“蹺蹺板樂園里一共有多少人?”應(yīng)該知道什么條件?(有多少人在玩?旁邊有多少人?)大家想一想我們第一步要先算什么?(有多少人在玩蹺蹺板)根據(jù)題目的哪些條件可以求出“有多少人在玩蹺蹺板”?(有3個蹺蹺板,每個蹺蹺板上有4人在玩)怎樣列式?[4X3=12(人)]為什么用乘法計算?(因為它是求3個4是多少,所以用乘法計算)現(xiàn)在我們已經(jīng)知道有12人在玩蹺蹺板,那第二步該算什么?(蹺蹺板樂園里一共有多少人)怎樣列式?[127=19(人)]誰會用一個算式表示?[4X37=19]請一個同學說一說每一步表示的意思。應(yīng)用題解答完要記住寫答案。

一、創(chuàng)設(shè)情境,導入新課教師邊放課件邊講故事):今天老師給你們講一個“猴媽媽分桃”的故事。有一天,一群小猴到山下去玩,走著走著,看到一棵桃樹上結(jié)滿了又大又紅的桃,就摘了很多?;丶液?,猴媽媽看到小猴們拿了這么多桃回來,可高興了,說:“媽媽分桃給你們吃。”二、合作交流,探索新知1、動手操作,探究方法(1)提出問題。師:小猴摘了多少個桃?準備每只小猴分3個,可分給幾只猴子?(板書:12個桃,每只小猴分3個,可以分給幾只小猴?)(2)學生列式:12÷3=(3)分一分學生小組合作,動手分一分。(可以用其他的物體代替)(4)說一說分的過程可能有以下幾種:第一種:先分給第一只小猴3個桃,再分給第二只小猴3個桃,然后給第3只小猴3個桃,最后3個桃正好分給第四只小猴。……12個桃可分4只猴子。

一、教材分析《3的倍數(shù)的特征》是人教版實驗教材小學數(shù)學五年級下冊第19頁的內(nèi)容,它是在因數(shù)和倍數(shù)的基礎(chǔ)上進行教學的,是求最大公因數(shù)、最小公倍數(shù)的重要基礎(chǔ),也是學習約分和通分的必要前提。因此,使學生熟練地掌握2、5、3的倍數(shù)的特征,具有十分重要的意義。教材的安排是先教學2、5的倍數(shù)的特征,再教學3的倍數(shù)的特征。因為2、5的倍數(shù)的特征僅僅體現(xiàn)在個位上的數(shù),比較明顯,容易理解。而3的倍數(shù)的特征,不能只從個位上的數(shù)來判定,必須把其各位上的數(shù)相加,看所得的和是否是3的倍數(shù)來判定,學生理解起來有一定的困難,因此,本課的教學目標,我從知識、能力、情感三方面綜合考慮,確定教學目標如下:1、使學生通過理解和掌握3的倍數(shù)的特征,并且能熟練地去判斷一個數(shù)是否是3的倍數(shù),以培養(yǎng)學生觀察、分析、動手操作及概括問題的能力,進一步發(fā)展學生的數(shù)感。

1、完成練習十五第1題。(1)學生獨立完成計算。(2)指名板演,交流計算方法。提問:你是按照什么運算順序計算的?指出:分數(shù)加減混合運算的運算順序與整數(shù)相同,參與運算的幾個分數(shù),可以分步通分,分步計算;也可以一次通分,再計算。計算結(jié)果要約成最簡分數(shù)。[練習十五里異分母分數(shù)加減混合運算的純計算題比較少,僅第1題里有4道。教學中適當補充三個分數(shù)加減混合運算的練習也是可以的,但不要耗費學生過多的學習精力。如果學生計算發(fā)生錯誤,要仔細分析原因,有針對性地采取有效的解決措施。]2、完成練習十五第2題。(1)讀題,理解題意,說說自己的思路。(2)學生獨立完成解答。10(3)+ 5(1)+ 6(1)= 30(9)+ 30(6)+ 30(5)= 30(20)= 3(2)(小時)(3)交流匯報,集體評價。3、完成練習十五第3題。(1)學生獨立完成(1)、(2)小題,說說自己是怎樣想的?(2)鼓勵學生根據(jù)題中的已知條件提出用分數(shù)加、減法計算的不同問題,可以是一步計算的,也可以是兩步計算的,并讓學生嘗試解決提出的一些問題。

三、總結(jié)規(guī)律、形成概念通過學生積極討論,充分調(diào)動了學生的積極參與學習,既發(fā)揮了學生學習的主動性,又培養(yǎng)了學生的發(fā)散性思維,引導學生總結(jié)出:有的分數(shù)可以化成有限小數(shù),有的分數(shù)不可以化成有限小數(shù),請同學們再看一看什么樣的分數(shù)可以化成有限小數(shù)?什么樣的分數(shù)不可以化成有限小數(shù)?啟發(fā)學生從分母的最小公倍數(shù)著手。 最后總結(jié)出:一個最簡分數(shù),如果分母中只含有素因數(shù)2和5,再無其它素因數(shù),那么這個分數(shù)就可以化成有限小數(shù),否則就不能化成有限小數(shù)。 例題2,請把下列小數(shù)化成分數(shù),說說你是怎樣把小數(shù)化成分數(shù)的? 0.06,0.4,1.8,2.45,1.465, 歸納:(學生為主,教師點撥)1、原來有幾位小數(shù),就在1后面寫幾個零作分母。原來的小數(shù)去掉小數(shù)點作分子。2、小數(shù)化成分數(shù)后,能約分的要約分。常用的因數(shù)是2和5。 對于小數(shù)如何化成分數(shù)的題目,課前了解到學生在小學時已學過把小數(shù)如何化成分數(shù)的方法,因而以學生練習為主,加以操練并鞏固,有錯誤的及時糾正。

1、說課內(nèi)容:義務(wù)教育課程標準實驗教科書數(shù)學(人教版)五年級下冊第69頁例1、例2。2、教材地位及作用:學生在三年級已初步認識分數(shù),但那時所學的分數(shù)都是分子小于分母的分數(shù),所以,學習這節(jié)內(nèi)容,使學生比較全面地理解分數(shù)概念與培養(yǎng)對分數(shù)的數(shù)感,起著重要的作用。3、教學目標的確定:當今時代是經(jīng)濟全球化,文化多元化,社會信息化的時代,所以教育也要追隨時代發(fā)展的步伐。遵循課標提出的“為了每一位學生的發(fā)展”教育理念,確定本課教學目標如下:①使學生理解真分數(shù)和假分數(shù)的意義;②通過學習真分數(shù)、假分數(shù),加深學生對分數(shù)意義的理解;③使學生掌握真分數(shù),假分數(shù)的特征;④培養(yǎng)學生的觀察、比較、分析及概括的能力;⑤使學生在思考中、討論中,體會學習數(shù)學的快樂,體驗成功的喜悅。4、教學重點、難點:

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.

“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. Recite the new words and expressions about the last school trip in the aquarium, including their pronunciation and intonation

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. 運送;運輸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.

教學目標1.知識目標:(1)學習What are you going to be when you grow up?/How are you going to do that?句式。(2)學會用英語描述有關(guān)職業(yè)的表達法。2.能力目標:(1)能夠談?wù)摓閷崿F(xiàn)理想所做出的打算和安排。(2)能夠談?wù)撐磥碜约号c他人理想的職業(yè)及原因。(3)能用英語描述課余時間的活動安排,最終具備表達綜合信息的能力。3.情感目標:新學期到來之際,讓他們在學習、體育、飲食、特長、讀書等方面制定計劃,教育學生合理安排自己的課外生活,思考自己的理想職業(yè)及適合自己的職業(yè)。教學重點、難點本單元的重點為“be going to”表將來,want to be, what,where, when,how引導的特殊疑問句。難點是語言目標的實現(xiàn)。教材分析本單元以I am going to be a basketball player為話題,共設(shè)計了三部分的內(nèi)容:一、Section A該部分有4個模塊。第一模塊圍繞Do you think these jobs are interesting?這一話題展開思維(1a)、聽力(1b)、口語(1c)訓練;

1 交通工具的比較此活動為小組活動。學生通過討論找出到達某一城市可乘坐的各種交通工具,并選擇最佳出行方式。Teacher:We’re going to Shanghai. How many ways can we use to get there? Yes, there are four ways: by bus, by plane, by train, by ship. Please discuss how you are going to get there.操作建議:(1)學生以小組為單位展開活動,談?wù)摫窘M所選擇的交通工具。(2)各組選代表向全班匯報,闡述本組所選擇的交通工具的利和弊。完成任務(wù)所需要的語言結(jié)構(gòu):We can go there by ship. It’s more comfortable and cheaper than any other transportation.We can go there by bus. It’s cheaper but it takes longer time.2 哪個城市更合適?此活動具有挑戰(zhàn)性。假設(shè)中國要舉行2014年世界杯足球賽,分別從歷史,人文,天氣等方面對各城市(北京,大連,上海,昆明)進行比較,選擇最佳舉辦城市。T: Imagine China is holding the 2014 FIFA World Cup. Which city do you think is the best for the World Cup, Beijing, Dalian, Shanghai or Kunming? Let’s work in groups. If you choose Beijing, please join the Team Red. If you chose Dalian, please join the Team White. If you choose Shanghai, please join the Team Blue. If you choose Kunming, please join the Team Green. Please show us its advantages. Then let’s see which team will win.

1. First, ... then, ... next, ... finally, ...首先,……然后,……接著,……最后,……這是英語中表達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通常你會聽到說英語國家的人在說 first, next, then, finally 和后面的內(nèi)容時,他們會做一些停頓。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。請看:how many修飾可數(shù)名詞復數(shù),how much修飾不可數(shù)名詞。但在用法上,同學們常犯如下錯誤: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,謂語動詞用單數(shù)。how many與how much的區(qū)別可簡記為:前how many:問“多少”,復數(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。

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. I have a sore back.I am tired. I can’t sleep.I have a cold. I have a headache.Report: If you have a headache, you should go to bed early. You should see the doctor. You should eat some medicine. 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,同時也可以讓他們復習一部分的表示人體部位的單詞,擴充知識.學習語言的過程也是一個不斷積累的過程,復習舊知識,增添新知識.通過小游戲,強化學生對Does she/he have…這個句子的運用能力.通過復習,自然的引到下面新知識的學習。充分利用表格,由句子到對話,再到文章,讓學生循序漸進. 提高學生的綜合語言運用能力,運用以前學過的知識來解決身邊的問題.Period 5 (Section B 3a—3c, selfcheck)教學內(nèi)容與分析:

二、說教學目標 1.會認“婆、脊”等7個生字,會寫“漏、喂”等13個生字,讀準多音字“哩、旋”,能正確讀寫“里屋、莫非”等詞語。2.有感情地朗讀課文,理解課文內(nèi)容,體會故事的趣味性。3.了解故事的特點,體會民間故事的魅力,并用自己的話復述課文。三、說教學重難點1.理解課文內(nèi)容,找出故事中具有吸引力的情節(jié)。(重點)2.了解故事的特點,能用自己的語言把故事復述出來。(難點)四、說教法學法1.自主學習法 要求學生課前要做好預習,了解課文內(nèi)容,對不認識的生字學會自己查字典,對不熟悉的詞語自己標記出來,在課堂上提出來集體討論。對課后習題在預習中要有自己的思考。 2.朗讀法 這篇課文語言幽默詼諧。要讓學生通過充分的朗讀了解故事的主要內(nèi)容,體會故事的主旨,并在弄通故事大意的基礎(chǔ)上能用自己的話復述故事。

一、創(chuàng)設(shè)情境,設(shè)置懸念,激趣導入。好的開端是一堂課成功的一半。正因為如此,我運用激趣導入,進行猜謎語、聽聲音比賽。利用課件引導學生的聽覺、視覺、思維想象多渠道運作起來,積極參與到學習中。而且我還特別設(shè)計了個別聲音用耳朵比較難以辨別,學生只好用眼睛揭開謎底,從而初步接觸課文“眼見為實”的主旨。最后出示“咕咚”的聲音,讓學生猜猜這樣的聲音通常在什么情況下會出現(xiàn),激發(fā)他們的想象力。讓學生模擬發(fā)“咕咚”聲,從而引出課題。并且告訴大家:千萬別小看這個有點奇怪的聲音,它可在森林中掀起了一場不大不小的風波呢。
