說明:在幫Li Lei提建議的同時,教育學生如何學好英語。第三課時教學目標1. 語言目標:a) 詞匯: Original, in style, haircut, the same as.b) 語言結構:My friend wears the same clothes and has the same haircut as I do.2. 能力目標:大多數學生能夠談論自己喜歡哪種服裝,提高查找信息的能力。3. 情感目標:學會如何與朋友相處,要有自己對時尚的看法。教學重點掌握一些重要詞匯。教學難點學會談論問題,并能提出書面建議。◆教學突破首先針對Erin的問題,提出個人的建議,模仿2c部分的對話展開雙人交際Pair-work;聽老師誦讀3a部分的信件,并找出LEFT OUT的問題所在;學生完成3b部分的內容,給Left Out提出書面的建議;學以口頭形式提出自己目前存在的某個問題,講給大家聽,讓同學們給自己提出一個建議,并作筆錄;學生兩、三個人分成一組,隨意性地進行口語交際,談論P14的第4部分的某個問題,相互交換意見。
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,談論本組所選擇的交通工具。(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。完成任務所需要的語言結構: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.
教學重點和難點:運用所掌握的語言描述,比較不同地點的特點。在練習中學習掌握英語比較級和最高級的用法。課前準備分配小組,每組五至六人。通過上網或翻閱報刊雜志等方法,確定旅游線路,做出基本的旅游計劃。教學設計:本節(jié)課流程圖 學法指導:1.由于這是一堂新課,在教學中應注意面向全體,發(fā)揮學生的主體性,引導學生積極參與,激發(fā)學生的求知欲和學習積極性,指導學生積極思維,主動獲取知識,養(yǎng)成良好的學習方法。逐步學會獨立解決問題。總之要盡可能調動學生的非智力因素促進智力因素的發(fā)展。教法選擇:1.電化教學法2.課堂討論法3.任務型教學法采用這些方法的目的是為了充分調動學生的學習積極性,使學生變被動學習為主動學習。通過電腦形象的演示,加強印象,提高興趣,突破難點,提高教學效率,進而增大教學的容量和信息量。充分體現教師為主導,學生為主體的教學原則。
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. 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)教學內容與分析:
區(qū)分賓語從句、定于從句和狀語從句賓語從句和狀語從句,都叫做主從復合句。賓語從句主要是中考必考的,是初中階段必掌握的從句,賓語從句主要是掌握三要素,所謂賓語從句,就是賓語在主從復合句當中充當賓語的一個句子,叫做賓語從句。主句的謂語動詞是及物動詞,后面如果是詞或者是短語的話,是簡單句,如果是句子的話,肯定是賓語從句。I know that he good at English.就是賓語從句,三要素,一要素是要注意連詞,連詞一共學了三類連詞,一類連詞是that口語當中可以省略,就像剛才說的那一句,I hear he is good at English.還有疑問代詞、疑問副詞,how where when,疑問代詞、疑問副詞。還有一類連詞weather是否的意思,不是狀語從句當中的如果,這一定要和如果區(qū)分開,這是是否。I don't know if he interested at English。賓語從句要注意if是連詞。第二要素是語序,要用陳述舉語序。比如說你家有幾口人,我們都說How many people are there in you family?但是這是簡單句,一旦說成賓語從句,你可以告訴我你家有幾口人嗎?Could you tell me how many people there are in you family ?
"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好!歡迎你!請做一下自我介紹。認識一下你的新同學。”通常在課上老師會這樣說。你會說什么呢?“噢,不!”與陌生人談話太困難了。但是這也很有意思,并且你還能交到朋友。你該怎么做呢?閑聊。閑聊指得是禮貌的對話?!巴蹰且粋€很棒的乒乓球運動員,不是嗎?”“我希望自己能認識她,你呢?“今年的雨水很多,不是嗎?”反意疑問句是一種禮貌用語。為了使得談話成功,你應該知道怎樣去進行閑聊。你還應該知道與不同的人該談論什么樣的話題。認真的學習這個單元吧,下次在英語課上,你會發(fā)現與大家展開談話是一件很容易的事情,不信我們來試試。)

(6)交流。6的乘法口訣一共有幾句?口訣中的第一個數與算式中的第二個因數相同,表示什么?口訣中的第二個數與算式的第一個因數相同,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?教師在學生發(fā)言的基礎上鼓勵學生大膽說、想出不同記口訣的方法。(7)應用"做一做"第1題(學生半獨立完成):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運用所學的口訣口答擺4個、6個、3個、5個六邊形所需要向小棒數。"做一做"第2題(獨立完成):①將第2題改為填空題,在圓圈內填寫正確的積;②口答得數,并說一說所用口訣。
教后反思本節(jié)課給學生創(chuàng)設了良好的活動空間,把學生實際生活中聽說過的見到的平均分現象展示給學生看,把生活和數學聯(lián)系起來,在學生感受“同樣多”的基礎上概括出什么叫平均分。揭示平均分這一數學知識在生活中的應用,之后突出了學生三次實際操作。第一次,小組同學互相分水果,重視學生分的結果。體會感受“平均分”的含義。第二次,重視分法:15個橘子平均分成5份。體現了學生對物品的不同分法,建立了平均分的概念。第三次,分礦泉水,通過份數變化,觀察分的就結果,深刻體會“平均分”,為認識除法積累豐富的知識。為學生營造探索的空間。第二課時:平均分的認識(二)教學內容鞏固“平均分”。課本第15頁的例題3。教學目標1.鞏固“平均分”的概念,知道平均分就是每一份分得結果同樣多。
三維目標1.知識與技能(1)讓學生經歷用7、8、9的乘法口訣求商的過程,掌握用乘法口訣求商的一般方法。(2)使學生會綜合應用乘、除法運算解決簡單的或稍復雜的實際問題。2.過程與方法在解決問題的過程中,讓學生初步嘗試運用分析、推理和轉化的學習方法。3.情感、態(tài)度與價值觀讓學生在學習中體驗到成功的喜悅,增強學生學好數學的信心。重、難點與關鍵1.重點:使學生熟練應用乘法口訣求商,經歷從實際問題中抽象出一個數是另一個數的幾倍的數量關系的過程,會用乘法口訣求商的技能解決實際問題。2.難點:應用分析推理將一個數是另一個數的幾倍是多少的數量關系轉化為一個數里面有幾個另一個數的除法含義。3.關鍵:以解決問題為載體,培養(yǎng)學生的數感。
三、利用乘法口訣進行計算1.復習口訣的含義。任意挑出一句乘法口訣(兩個因數不同的),讓學生說說它表示什么意思。如"七八五十六",使學生知道它既表示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行計算的活動。(1)已知兩個因數求積的游戲。方法是:請一位學生隨意說出一個兩位數,另一位學生則將這個兩位數的十位數字與個位數字相乘,并算出結果,如果結果又是一個兩位數,再將這個兩位數的十位數字和個位數字相乘,直至結果是一位數或零。如,一位學生說:"79",另一位學生則口算:7X9=636X3=181X8=8;一位學生說:"58":另一位學生口算:5X8=404X0=0(告訴學生0和一個數相乘得零)一位學生報了3個數以后,互換角色進行。(2)已知積求兩個因數的游戲。
課題十: 解決問題(一)教學內容:解決問題教學目標:1、會解決有關小數除法的簡單實際問題。2、能探索出解決問題的有效方法,并試圖尋找其他方法,能表達解決問題的過程。教學過程:一、引入新課:前面我們學習了小數除法的計算,那么你會解決下面的問題嗎?(板書課題)二、自主探索(出示例11)1、先獨立思考解答。2、小組內交流,可以先算什么?3、小組匯報,全班交流,說說不同的思路。再指名說說。三、鞏固練習1、“做一做”獨立完成,全班交流。再指名說說不同的解題思路。2、完成P34 3師:你從此題中收集到了哪些信息?要解決什么問題?如何思考?生先獨立思考,再小組交流,匯報分析過程。師小結,解答問題時要找準有直接關系的條件或信息。
教學內容:整數乘法運算定律推廣到小數乘法 (P.12頁例8和“做一做”,練習二第2題。)教學要求: 使學生理解整數乘法的運算定律對于小數同樣適用,并會運用乘法的運算定律進行一些小數的簡便計算。教學重點: 乘法運算定律中數(包括整數和小數)的適用范圍。教學難點: 運用乘法的運算定律進行小數乘法的的簡便運算。教學用具:投影片若干張。教學過程:一、激發(fā):1、計算:25×95×4 25×32 4×48+6×48 102×562、在整數乘法中我們已學過哪些運算定律?請用字母表示出來。根據學生的回答,板書:乘法交換律 ab=ba乘法結合律 a(bc)=(ab)c乘法分配律 a(b+c)=ab+ac2、讓學生舉例說明怎樣應用這些定律使計算簡便。(注意學生舉例時所用的數。)3、出示教材P.9頁的3組算式:下面每組算式左右兩邊的結果相等嗎?
3、教學例3(1)讀題理解題意后,提出“嬰兒每分鐘心跳的次數比青少年多 ”表示什么意思?(組織學生討論,說說自己的理解)(2)引導學生將句子轉化為“嬰兒每分鐘比青少年多跳的次數是青少年每分鐘心跳次數的 ”。著重讓學生說說誰與誰比,把誰看作單位“1”。(3)出示線段圖,學生討論交流,結合例2的解題方法,學生獨立列式計算后全班交流兩種解題方法。解法一:75+75× =75+60=135(次)解法二:75×(1+ )=75× =135(次)4、鞏固練習:P21“做一做”(列式后讓學生說說算式各部分表示什么)三、練習1、練習五第2、3題:引導學生抓住題目中關鍵句子分析,找到誰與誰比,誰是表示單位“1”的量。2、練習五第3、4題:學生依據例題引導的解題方法,獨立完成3、4題。四、布置作業(yè)練習五第7、8、9、10題。
教學追記:本節(jié)課的內容相對而言較容易掌握,因而學生在學習中并沒有出現什么困難。教學中,我兩種方法并重,并讓學生理解兩種方法的殊途同歸之處。對于類型稍有不同的題目,如“做一做”第2題,以人數為比例進行分配的,我在教學時添加了一道例題,教學后再讓學生獨力完成第2題,這樣的教學讓學生學得較為輕松,也對這種類型題掌握得較扎實。4、整理和復習整理復習(1)復習目標:使學生進一步掌握本章所學的基本概念和計算法則,提高學生的計算能力和解題能力。復習重點:分數除法的計算方法,化簡比。復習難點:正確計算分數除法。復習過程:一、復習分數除法的意義和計算法則1、這一章我們學習了分數除法的有關知識.請大家回憶一下分數除法有幾種類型?(1)分數除以整數,例如 ÷5;(2)一個數除以分數,它又包括整數除以分數,例如20÷ ;和分數除以分數,例如÷ 。(3)做第52頁“整理和復習”的第2題。2、分數除法的意義
蔡元培的道德風范和人格力量,具有震撼人心的作用,深為世人所欽仰?!叭耸揽!薄吧屏嫉纳鐣颓f嚴的人生的模范”(國立音樂??茖W校師生1936年1月《祝蔡孑民先生千秋詩》)的贊譽,對他來說絕非溢美之詞。任鴻雋稱他具有“處處為人無我的真精神”;“對人接物,似乎有兩個原則,一個是尊重他人的人格,決不愿意以自己的語言和行動使人感到一點不快或不便,一個是承認他人的理性,以為天下事無不可以和平自由的方法互相了解或處理?!薄暗诠x一方面,蔡先生卻是特立不屈、勇往直前、絲毫不退、毫不假借的斗士?!保ㄖ貞c《中央日報》1940年3月24日)他的學生馮友蘭也回憶說,在蔡先生身邊,感同光風霽月,他的人格能造成一種氣象。沐浴在這種氣象之中,就不能不為他的人格所感化。蔡元培身居高位,一生廉潔,自奉儉樸,直至晚年仍是全家租賃房屋居住,他酷愛的書籍也分散在北平、上海、南京、杭州等地,沒有一個歸攏庋藏的地方。蔡元培這種真誠待人、無私奉獻、光明磊落的精神,源于他對國家、對民族、對事業(yè)、對學生深深的眷戀和崇高的責任感。他的這種浩然正氣和高尚道德情操,至今仍是公務人員的楷模。
