一. 教材分析1. 本單元的中心話題是“計(jì)算機(jī)(Computers)”,內(nèi)容涉及計(jì)算機(jī)的發(fā)展歷史,計(jì)算機(jī)的應(yīng)用等。本節(jié)課是該單元的第一課時(shí),我將Warming up, Pre-reading and Comprehending這四部分整合為一節(jié)精讀課。其中。Reading部分是題為WHO AM I?的文章,以第一人稱的擬人手法介紹了計(jì)算機(jī)發(fā)長(zhǎng)演變的歷史和計(jì)算機(jī)在各個(gè)領(lǐng)域的應(yīng)用,其主旨是表達(dá)計(jì)算機(jī)的發(fā)展變化之快以及在生活中用途之廣。而Warming up部分以圖片的形式展現(xiàn)了計(jì)算機(jī)的發(fā)展歷程;Pre-reading中的問題和排序分別是為了預(yù)測(cè)語(yǔ)篇的內(nèi)容和測(cè)試學(xué)生對(duì)計(jì)算機(jī)歷史了解的情況;Comprehending則通過各項(xiàng)練習(xí)訓(xùn)練學(xué)生的閱讀技能,從而加深對(duì)文章的理解。可見這幾部分是一個(gè)有機(jī)的整體。2. 教學(xué)目標(biāo):1) 語(yǔ)言目標(biāo):重點(diǎn)詞匯及短語(yǔ):abacus, calculate, calculator, PC, laptop, PDA, robot, analytical, technological, universal, mathematical, artificial, intelligent, network, explore, in common, as a result.重點(diǎn)句子:a. My real father was Alan Turing, who in 1963 wrote a book to describe how computers could be made to work, and build a “universal machine” to solve any mathematical problem.
Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times. The first and listening is extensive listening and the second and third listening is intensive listening. In the first time, They are required to listen a material including Part 1 and Part 2 and choose the best summary of the listening text. After they choose the right answer, They also need work in group to explain what is wrong with the others. Then I will make a conclusion that we should pay attention to the first paragraph and last paragraph and some keys to get the main idea. By doing this, their capacity of generalization will have a great improvement.Before the second listening, I will ask students to scan the blank on the power point quickly and ask them to note down some key words .Then ask them to listen to the Part 1again and fill the first column of the chart. Maybe some students just show the ideas of these three scientists an still can’t catch their development of gravity. Therefore, I will ask them to listen to Part 2 again and fill in the rest. After finish the listening, I will give them ten minutes to discuss with their partner. I will also guidethem to improve their answers when they discuss with others.
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill
Good afternoon, teachers, It’s my great pleasure to be here sharing my lesson with you.The content of my lesson is Senior English Book 3 Unit 5 Canada —— “The true North”.I’ll be ready to begin this lesson from five parts. Analysis of the teaching material,the teaching methods,the studying methods, the teaching procedure,and Blackboard design.First, let me talk about the teaching material.Part 1 Teaching Material:This unit is about the introduction of Canada. By studying of this unit,we’ll enable the students to learn the geography, population, main cities, and natural beauty, natural resources of Canada. Through the training of the unit, it also requires students to learn some Language skills such as the expressions of position and emotions.So it plays an important part in the English teaching in this book.After studying the teaching material and analyzing the rule of children’s growing of mind,I think the teaching aims are the followings:1.Knowledge objects:(1) make the students learn some new words and phrases(2) make the students understand the content of the lesson.2.Ability objects:(1)To develop the Ss’ abilities of listening, speaking, reading and writing. Especially reading and speaking ability.(2) learn to talk about the characters of Canada in English(3)To train the Ss’ ability of working in pairs.3.Emotion objects:(1)Enable students to understand the characters of Canada..(2)Stimulate Ss to work hard to make China stronger.Part 2 Teaching Methods:I think helping students learn to master new words and phrases and improve the students’ reading and speaking ability is import and the difficult.According to the analysis of the teaching material and the import points and the difficult points,I will use the following teaching methods : question-guiding approach; fast-reading and careful reading; multi-media teaching methods; discussion

尊敬的老師們、敬愛的同學(xué)們:王國(guó)維提到過做學(xué)問有三重境界,其中第二重“衣帶漸寬終不悔,為伊消得人憔悴”,談的是做學(xué)問需要執(zhí)著追求。今天我在國(guó)旗下講話的內(nèi)容便是“讓我們學(xué)習(xí)和生活中學(xué)會(huì)堅(jiān)持”。我經(jīng)常問自己:什么叫堅(jiān)持,為誰堅(jiān)持,堅(jiān)持又能帶給我什么?為此我先講一個(gè)故事:古希臘大哲學(xué)家蘇格拉底在開學(xué)第一天對(duì)他的學(xué)生們說:“今天你們只學(xué)一件最簡(jiǎn)單,也是最容易的事兒:每人把胳膊盡量往前甩,然后再盡量往后甩?!闭f著,蘇格拉底示范做了一遍:“從今天開始,每天做300下,大家能做到嗎?”學(xué)生們都笑了:“這么簡(jiǎn)單的事,有什么做不到的!”過了一個(gè)月,蘇格拉底問學(xué)生:“每天甩手300下,哪個(gè)同學(xué)堅(jiān)持了?”有90%的學(xué)生驕傲地舉起了手。又過了一個(gè)月,蘇格拉底又問。這回,堅(jiān)持下來的學(xué)生只剩下了8成。一年過后,蘇格拉底再一次問大家:“請(qǐng)告訴我,最簡(jiǎn)單的甩手運(yùn)動(dòng),還有哪幾個(gè)同學(xué)堅(jiān)持了?”這時(shí),整個(gè)教室里只有一個(gè)人舉起了手。這個(gè)學(xué)生就是后來成為古希臘另一位大哲學(xué)家的柏拉圖。
得出這樣便于口算的道理,也為幫助學(xué)生探索“兩位數(shù)乘兩位數(shù)”的豎式計(jì)算方法埋下了伏筆。與此同時(shí)也允許學(xué)生把12用他們認(rèn)為更便于計(jì)算的方法進(jìn)行計(jì)算。另一種是直接用豎式計(jì)算。豎式的擺法學(xué)生肯定沒問題,對(duì)于第一步如何計(jì)算也難不倒學(xué)生,關(guān)鍵是第二步、第三步,通過學(xué)生自己探索算法,讓學(xué)生弄清第二步、第三步為什么這樣寫?根據(jù)學(xué)生的匯報(bào),強(qiáng)調(diào)書寫格式并板書,用個(gè)位上的2去乘24,乘得的積是表示48個(gè)一,積的末尾要和個(gè)位對(duì)齊;用十位上的1去乘24,乘得的積表示24個(gè)十,乘得積的末尾要和十位對(duì)齊(個(gè)位上的0省略不寫);最后把兩次乘得的積相加。(這樣利用遷移原理,使學(xué)生一步一步地加深對(duì)算理和算法的認(rèn)識(shí)和理解,不但突出了教學(xué)重點(diǎn),而且突破了教學(xué)難點(diǎn)。)3、教師點(diǎn)撥:筆算乘法時(shí):(1)從個(gè)位乘起,先用第二個(gè)因數(shù)的個(gè)位上的數(shù)依次去乘第一個(gè)因數(shù)的每一位上的數(shù),得數(shù)末位和第一個(gè)因數(shù)的個(gè)位對(duì)齊;
(四)、反饋練習(xí)1.口算:看誰算得又對(duì)又快。學(xué)生在書上做第43頁(yè)的第5題,限時(shí)2分鐘。學(xué)生做題,教師計(jì)時(shí),做后集體訂正,并指名說說自己是怎樣做75-5,90+8這兩道題的。[通過計(jì)時(shí)計(jì)算,可提高學(xué)生的自信度,通過說兩題的計(jì)算過程,加強(qiáng)對(duì)新知的鞏固程度。]2.做第43頁(yè)的第6題。在這里將首先運(yùn)用多媒體教學(xué)課件表現(xiàn)出課本上兩人對(duì)話的場(chǎng)景(有老師3名,學(xué)生40名,45瓶礦泉水夠嗎?),使學(xué)生看后發(fā)表自己的意見,如果自己在此時(shí)遇到這樣的問題會(huì)怎么辦,并說說自己是怎樣想的,會(huì)用算式表達(dá)的同學(xué),可以列出算式來。[充分利用現(xiàn)代化設(shè)備為學(xué)生的思維創(chuàng)設(shè)情境,使學(xué)生的思維盡可能地與現(xiàn)實(shí)生活相聯(lián)系,以生活實(shí)際中的問題來鍛煉學(xué)生的思維能力,并讓學(xué)生體會(huì)到生活中處處有數(shù)學(xué)。為了讓學(xué)生有不同的發(fā)展,可讓程度較好的學(xué)生把自己的思維過程抽象成數(shù)學(xué)算式。]
1.揭示課題那么,這個(gè)運(yùn)算定律是否對(duì)分?jǐn)?shù)加法也適用呢?現(xiàn)在我們就來研究這個(gè)問題。板書課題:整數(shù)加法運(yùn)算定律推廣到分?jǐn)?shù)加法。2.研究運(yùn)算定律對(duì)分?jǐn)?shù)加法的適用性出示式題:提問:上面每組算式的左右兩邊有什么關(guān)系?得數(shù)是否相等?先指名學(xué)生練習(xí),算出得數(shù)后,再引導(dǎo)學(xué)生觀察。提問:這兩組試題有何共同之處?組織學(xué)生開展小組討論,共同概括總結(jié)出他們的共同點(diǎn),得出規(guī)律性的認(rèn)識(shí),從而使學(xué)生體會(huì)到整數(shù)加法運(yùn)算定律,對(duì)分?jǐn)?shù)加法同樣適用。通過討論明確:加法的交換律、結(jié)合律中的數(shù),既包括了整數(shù),又包括了小數(shù)和分?jǐn)?shù)?!驹O(shè)計(jì)意圖】通過具體的實(shí)踐活動(dòng),直觀感知了加法運(yùn)算定律同樣也適用于分?jǐn)?shù)加法。這種通過自己實(shí)踐得來的東西,學(xué)生理解得更透,掌握得更牢。
一.說教材。我說課的內(nèi)容是人教版課程標(biāo)準(zhǔn)實(shí)驗(yàn)教科書六年級(jí)上冊(cè)的分?jǐn)?shù)除法單元中的例1和例2。例1是分?jǐn)?shù)除法的意義認(rèn)識(shí),例2是分?jǐn)?shù)除以整數(shù)的計(jì)算。在這之前學(xué)生已經(jīng)掌握了整數(shù)除法的意義和分?jǐn)?shù)乘法的意義及計(jì)算,而本課的學(xué)習(xí)將為統(tǒng)一分?jǐn)?shù)除法計(jì)算法則打下基礎(chǔ)。例1先是整數(shù)除法回顧,再由100克=1/10千克,從而引出分?jǐn)?shù)除法算式,通過類比使學(xué)生認(rèn)識(shí)到分?jǐn)?shù)除法的意義與整數(shù)除法的意義相同,都是‘已知兩個(gè)因數(shù)的積和其中一個(gè)因數(shù),求另一個(gè)因數(shù)的運(yùn)算’。例2是分?jǐn)?shù)除以整數(shù)的計(jì)算教學(xué),意在通過讓學(xué)生進(jìn)行折紙實(shí)驗(yàn)、驗(yàn)證,引導(dǎo)學(xué)生將‘圖’和‘式’進(jìn)行對(duì)照分析,從而發(fā)現(xiàn)算法,感悟算理,同時(shí)也初步感受數(shù)形結(jié)合的思想方法。根據(jù)剛才對(duì)教材的理解,本節(jié)課的教學(xué)目標(biāo)是:1、理解分?jǐn)?shù)除法的意義與整數(shù)除法的意義相同。2.理解分?jǐn)?shù)除以整數(shù)的計(jì)算原理,掌握計(jì)算方法,并能正確的進(jìn)行計(jì)算。
各位老師、同學(xué)們:大家好!今天我國(guó)旗下講話的題目是《培養(yǎng)良好的學(xué)習(xí)習(xí)慣》。你們知道科技大學(xué)少年班嗎?你們知道13歲就進(jìn)入科大少年班的周峰嗎?你們知道他為什么這么小就能成為大學(xué)生嗎?在談到自己成績(jī)優(yōu)異的原因時(shí),周峰認(rèn)為自己成功的秘訣就是從小養(yǎng)成了良好的學(xué)習(xí)習(xí)慣。周峰的學(xué)習(xí)自覺性特別強(qiáng),從不需要?jiǎng)e人提醒,更不需要?jiǎng)e人強(qiáng)制,該學(xué)習(xí)的時(shí)候就一心一意學(xué)習(xí),該玩兒的時(shí)候就輕輕松松地玩兒。學(xué)習(xí)時(shí),他總是全神貫注,思想從不開小差,即使稍有走神,也能立即作出調(diào)整??茖W(xué)歸納法的奠基人培根在談到習(xí)慣時(shí)也深有感觸地說:“習(xí)慣真是一種頑強(qiáng)而巨大的力量,它可以主宰人的一生,因此,人從幼年起就應(yīng)該通過教育培養(yǎng)一種良好的習(xí)慣?!蹦菓?yīng)該培養(yǎng)哪些良好的學(xué)習(xí)習(xí)慣呢?下面就為大家介紹四種良好的學(xué)習(xí)習(xí)慣,作為同學(xué)們努力的方向。1.一心向?qū)W的習(xí)慣:科學(xué)家巴斯德說:“機(jī)遇只偏愛有準(zhǔn)備的頭腦。”一心向?qū)W的頭腦便是有準(zhǔn)備的頭腦。同樣是水壺,普通人燒出的是開水,而瓦特卻燒出了蒸汽機(jī);同樣是手被草葉子拉破了,普通人只會(huì)想到埋怨草的無情和自己的粗心,而魯班卻想到了發(fā)明鋸;同樣是看到蘋果從樹上掉下來,果農(nóng)見了只感到心疼,而牛頓卻由此發(fā)現(xiàn)了萬有引力定律。
