一、說教材:1、教學內容:北師大版小學數(shù)學三年級下冊第28-29頁。2、教材簡析:這部分知識的教學是建立在上節(jié)課學習了兩位數(shù)乘兩位數(shù)的算法,以及對進位的乘法也有一定經驗的基礎上進行的,目的是使學生進一步掌握兩位數(shù)乘兩位數(shù)(進位)的算法。本節(jié)課主要通過“電影院”這一學生熟悉的生活情境,在引導學生觀察的基礎上,培養(yǎng)學生的估算意識和估算能力;讓學生在具體的教學活動中,拓展學生的思維,體驗算法策略的多樣化,進一步掌握兩位數(shù)乘兩位數(shù)(有進位)的算法,并能解決一些簡單的實際問題。二、、教學目標:▲知識與技能:(1)結合“電影院”的具體情境,進一步掌握兩位數(shù)乘兩位數(shù)(有進位)的計算方法。(2)對兩位數(shù)乘兩位數(shù)(有進位)能進行估算和計算。(3)能解決一些簡單實際問題。
為了講清重點、難點,使學生能達到本節(jié)設定的教學目標,我再從教法和學法上談談:五、說教法學法我依據(jù)“教學有法,教無定法,貴在得法”,同時為了達到既定的教學目標,突出重點,突破難點。本節(jié)課我采用的教學方法主要有創(chuàng)設情境法,引導啟發(fā)法,同時輔以講練結合,借助現(xiàn)代化的教學手段,以達到良好的教學效果。根據(jù)新課標的要求,同時又設計了與教法相適應的學法,我將“學習的主動權還給學生”,通過自主探索,合作交流等方式自主學習,真正讓數(shù)學教學的課堂變成學生的課堂。六、說教學準備為了更好的達成本節(jié)課的課堂教學目標,老師學生需要做如下的教學準備:1、教具:根據(jù)教材內容自制的多媒體課件等教具。2、學具:學生以小組為單位準備表格等學具。
1、說教材:本節(jié)課是北師大版小學數(shù)學四年級下冊第94-95頁。猜數(shù)游戲是在學生已經學習了用字母表示數(shù)、方程、等式的性質等知識的基礎上進行學習的。本節(jié)課主要學會用等式的性質解“ax±b=c”這樣的方程,并能用方程解決簡單的實際問題。教材通過笑笑和淘氣猜數(shù)游戲,利用等量關系列出方程,重點是利用等式的性質解方程,能口頭檢驗,形成檢驗的意識。本節(jié)課我通過游戲激發(fā)學生的興趣,使學生體會方程的作用,并產生學習方程解法的愿望,為以后學習解方程、用方程思想解決問題打下重要基礎。2、說教學目標:通過猜數(shù)游戲的這個情景,讓學生會解形如“ax±b=c”的方程,并會簡單應用,讓學生在此過程中,體驗解方程的思路,并掌握方法。在情感、態(tài)度、價值觀方面,通過游戲,訓練學生的數(shù)學思維能力,養(yǎng)成善于思考的習慣。3、說重、難點:本節(jié)課的重點是會解形如“ax±b=c”的方程,并會簡單應用;難點是利用等式的性質解方程
(三)、鞏固反饋師:同學們的表現(xiàn)真的令我出乎意料,你們太聰明了,今天我就帶大家去數(shù)學王國去參觀,敢去嗎?如果你們能闖關成功就可以免費進入王國的游戲宮,有信心嗎?(激勵學生,讓同學們很快進入鞏固練習這個環(huán)節(jié)中來)第一關:逛同學恩喜愛的食品店(這一關的設計采用搶答的方式進行,更進一步激發(fā)學生的學習興趣,而且鞏固了本課重點——計算規(guī)律。)第二關:我們來到了你們的媽媽喜歡服裝店(這一關先讓學生獨立嘗試,并抽生板演,全班訂正,注意強調答語的寫法。)第三關:現(xiàn)在我們來到了養(yǎng)雞場。(這一關仍然采用搶答的方式進行,這道題目主要考察同學們對第二條規(guī)律的掌握情況)第四關:進入數(shù)學王國繼續(xù)玩搶答游戲和猜一猜活動(這個環(huán)節(jié)讓學生體會到學習的樂趣)
《比的化簡》是北師大版六年級上冊第52——53頁的教學內容,主要學習化簡比的方法。教材聯(lián)系學生的生活創(chuàng)設問題情境,讓學生在解決問題的過程中加深對比的意義的理解,進一步感受比、除法、分數(shù)的關系,體會化簡比的必要性,學會化簡比的方法。在這之前,學生早已學過“商不變的性質”和“分數(shù)的基本性質”,最近又認識了比,初步理解了比的意義,以及比與除法、分數(shù)的關系,大部分學生能較為熟練地求比值。比較而言,實際上化簡比與求比值的方法有相通之處,那么借助知識的遷移能幫助學生順利理解掌握新知識。二、說教學目標:知識與能力:會運用商不變的性質或分數(shù)的基本性質化簡比。過程與方法:在實際情境中,讓學生體會化簡比的必要性,在觀察、比較中理解什么是化簡比,,并能解決一些簡單的實際問題。情感、態(tài)度與價值觀:促進知識遷移,培養(yǎng)學生的概括能力。體驗知識的相通性以及數(shù)學與生活的聯(lián)系。
我說課的內容是北師大版四年級上冊第68-70頁的《秋游》,我將從教材、教法、學法、教學過程四個方面對本節(jié)課進行說課:一.說教材本節(jié)課是在學生掌握四舍五入法試商的基礎上進行教學的。此前,學生學習的除法都是一次試商成功不需要調商的。本課由秋游搭車的事件引出計算:每個年級各需幾輛車?先讓學生運用已有知識進行計算,發(fā)現(xiàn)不是所有的除法計算一次試商就能成功,需要對所估得的商進行調試,從而掌握除數(shù)是兩位數(shù)的除法筆算。結合教材的特點和學生的實際情況,我確定了如下教學目標:1、知識與技能:讓學生在具體情境中,經歷四舍五入法試商后進行調商的探索過程,理解試商后調商的原因。并能正確地進行除數(shù)是兩位數(shù)(商是一位數(shù))的筆算。2、過程與方法:讓學生在探索計算方法和解決問題的過程中,感受數(shù)學與生活的聯(lián)系,提高學生的估算能力。
三、說教學重點、難點重點是小數(shù)乘法的豎式計算方法和積與乘數(shù)的大小關系。難點是小數(shù)乘法中乘數(shù)末位有0的計算。四、說學情在進行本節(jié)內容學習之前,學生已經學習了整數(shù)乘法的運算規(guī)律,小數(shù)的意義及其加減法,還有小數(shù)乘法的計算規(guī)律。本節(jié)內容重點是學會把小數(shù)乘法的運算方法應用到解決實際問題中去。根據(jù)四年級學生的認知特點和課堂注意力時間有限的特點,在教學中一定要提高課堂效率五、說教法、學法在本課教學中,我采取的教學方法是:1.通過復習,回顧計算規(guī)律,并把它應用到豎式中去。2.情境展示,把數(shù)學問題直接放在實際問題中來學習并解決。3.解決問題時采用自主探索、獨立思考和小組合作交流的學習方式。通過這些教學法激發(fā)學生學習的積極性和主動性,引導學生把學到的規(guī)律應用到現(xiàn)實生活中來解決實際問題。六、說教學過程(一)舉例說明積的小數(shù)位數(shù)與乘數(shù)小數(shù)位數(shù)的關系。通過比眼力,做一做,復習前一節(jié)課所學內容,為本節(jié)課打下基礎。
課程標準中明確指出:“小學數(shù)學的教學內容絕大多數(shù)可以聯(lián)系學生的生活實際,找準每一節(jié)教材內容與學生生活實際的“切入點”可讓學生產生一種熟悉感、親切感“,以及“數(shù)學教學活動中,教師應向學生提供充分從事數(shù)學活動的機會,幫助他們在自主探索的過程中真正理解和掌握基本的數(shù)學知識與技能?!币獙⑦@個理念落實在課堂教學中,就要求教師能根據(jù)教學的具體內容,選擇恰當?shù)膶W習方式,并巧妙創(chuàng)設學生主動探索的機會,變“接受學習”為“創(chuàng)造學習”,讓學生在觀察、操作、討論、交流、歸納、整理、概括的過程中學習新知,充分以學生為主體,逐步培養(yǎng)學生的創(chuàng)新意識,形成初步的探索和解決問題的能力。根據(jù)以上思想,本節(jié)課的設計我主要從尊重學生已有的知識經驗;在觀察與操作中去親身體驗知識的形成過程,掌握約分的方法。
知識與能力目標是:理解反比例的意義,能判斷兩個量是不是成反比例過程與方法目標是:通過討論、探究、觀察等活動,提高分析問題解決問題人的能力情感態(tài)度價值觀目標是:培養(yǎng)學生對學習數(shù)學的興趣,感知數(shù)學與生活的聯(lián)系。此外,根據(jù)我對教材的解讀,我將本節(jié)課的教學重點確定為:理解反比例的意義教學難點確定為:判斷兩個量是不是成反比例二、教法與學法新課標指出:學生是學習的主體,教師是學習的組織者、引導者和合作者,因此首先我采用情境教學法,通過創(chuàng)設情境,激發(fā)學生對學習數(shù)學的興趣,;再通過師生互動,探究式教學,為學生創(chuàng)設一個寬松的數(shù)學學習環(huán)境,相對教師的教法學生采用自主探索,研討發(fā)現(xiàn)的學習方法,讓學生成為學習的主人,發(fā)揮學生學習數(shù)學的積極性和主動性,最后利用練習法:通過適當?shù)木毩暎柟趟鶎W的知識,解決生活中簡單的實際問題
2.放大空間,升華思考由于我對教材的二度開發(fā)留給了學生足夠的探索空間,課上學生探索數(shù)學的熱情被充分調動,我們欣喜地看到:有的學生嘗試著不同平面圖形的旋轉;有的學生只用一種平面圖形,卻旋轉出不同的立體圖形;有的學生的思維并沒有停留在表象上,而是在深入地思考產生這一現(xiàn)象的原因……交流時學生的發(fā)現(xiàn)遠遠超出了我們的想象,這份生成帶給我們的是驚喜,是贊嘆,更是“以操作促思考”的教學行為結出的碩果。3.巧用課件,形成表象本節(jié)課,我充分運用現(xiàn)代信息技術將平面圖形經過旋轉形成立體圖形的過程生動、逼真地再現(xiàn)出來,幫助學生將抽象的空間想象化為直觀,進而形成表象,深植于學生的腦海中,促進了學生空間觀念的形成??傊?,在這節(jié)課上,我堅持把“促進學生發(fā)展”作為第一要素貫穿于課堂教學的始終,讓學生在充滿著民主、探究、思考的氛圍中,積極操作、主動思考,發(fā)展了學生的空間觀念。
四、說教法、學法我在教學中主要采用的教學方法是先學后教中的“兩學兩教”。輔之以多媒體教學手段(主要通過微課視頻的觀看學習)。本課學生的學習方法主要有:自主發(fā)現(xiàn)法、合作交流法、自學嘗試法等。1.學生在自主探究解答例題,求兩種品牌罐頭的合格率時,主要采用自學嘗試法,根據(jù)知識的遷移,學生能夠正確求出產品合格率。2.在總結小數(shù)、分數(shù)化成百分數(shù)的方法時,學生主要采用自主發(fā)現(xiàn),合作交流的方法。首先讓學生觀察例題板書,想一想怎樣把小數(shù)、分數(shù)化成百分數(shù),采用了“兵教兵”的方法,達到了人人參與的目的。當然,由于學生所處的文化環(huán)境,家庭背景和自身思維方式的不同,不同的學生所采用的方法也不盡相同,作為教師要尊重學生的選擇,允許學生用自己喜歡的方式學習數(shù)學。五、說教學過程
④聯(lián)系生活實際解決身邊的問題,讓同學初步感受數(shù)學與日常生活的密切聯(lián)系,體驗數(shù)學的應用,促進學生的發(fā)展。接下來,我再具體談一談這堂課的教學過程。3、說教學過程第一環(huán)節(jié):創(chuàng)設情境,激qing導入。同學們你們看屏幕上的是什么?(出示圖片)那么自行車車輪是什么形狀的?為什么車輪要設計成圓形?這里面有什么奧妙呢?學了今天的內容大家就會明白的。這節(jié)課我們就走進圓的世界去探尋其中的奧妙。板書課題:圓的認識設計意圖:通過生活中實際例子引入課題,一方面引起學生的學習興趣,另一方面為學習新知識做了鋪墊,從思想上吸引了學生主動參與學習的活動。這一環(huán)節(jié)的設計,主要是想體現(xiàn)數(shù)學就在我們的身邊,從而激發(fā)學生學習的興趣及學習的積極性。

一. 教材分析1. 本單元的中心話題是“計算機(Computers)”,內容涉及計算機的發(fā)展歷史,計算機的應用等。本節(jié)課是該單元的第一課時,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算機發(fā)長演變的歷史和計算機在各個領域的應用,其主旨是表達計算機的發(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)了計算機的發(fā)展歷程;Pre-reading中的問題和排序分別是為了預測語篇的內容和測試學生對計算機歷史了解的情況;Comprehending則通過各項練習訓練學生的閱讀技能,從而加深對文章的理解。可見這幾部分是一個有機的整體。2. 教學目標:1) 語言目標:重點詞匯及短語:abacus, calculate, calculator, PC, laptop, PDA, robot, analytical, technological, universal, mathematical, artificial, intelligent, network, explore, in common, as a result.重點句子: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.
Purpose of my design:To ask the students to do these two tasks will make the Ss predict the story of this passage. As a result, it will deepen Ss’ memory of this story because they will have their own understanding of this story.Step 3. While-readingTask 1. (Individual work _____min)Skimming: ask students to skim the text and the main ideas of each paragraph in this passage. Please read it quickly and then match the sentences with the letters.Task 2. (Individual work _____min)Scanning: read the text quickly and decide the whether the following statements are true or false and give reasons.Task 3. (Pair work _____min)Listen to the tape and fill in the banks. Then read the paragraph with expression to your partner.Task4 (individual work min)Listen to the tape again and write down the main idea in one sentence.Purpose of my design: Enable students to understand the given material better by using different reading skills. And proper competition can arouse the Ss’ interest in English learning. “Task-based” teaching method is used here todevelop the Ss’ ability of communication and also their ability of co-operation will be well trainedStep 4. Post-readingTask 1. (Individual work, pair work, group work, class work; _____min)Discussion (group of 4):1. If you were Hippomenes, would you run against Atlanta?2. Do you think Hippomenes deserved to win the race? Why or why not?Step 5. HomeworkPlease read the story again carefully after class and imagine: What will happen during the race between Hippomenes and Atlanta? Who do you think will win the race? Do you think Atlanta would marry Hippomenes? Write an end for the story with thses questions.Purpose of my design: Homework is so important and necessary for to master the knowledge they learned after class. It will check whether the Ss achieve the teaching aims.Part 5 Blackboard design
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
