英語站課件(篇3)
設(shè)計好教學(xué)設(shè)計是上好課的先決條件。在新課程條件下，隨著教師角色的轉(zhuǎn)變和學(xué)生學(xué)習(xí)方式的改變的要求，教學(xué)設(shè)計不再是教材內(nèi)容的簡單的詮釋、教學(xué)過程的簡單的安排、教學(xué)方法的簡單的展示，它的性質(zhì)、功能、方法已經(jīng)發(fā)生了很大的變化。它要求教師從新課程理念出發(fā)，在落實學(xué)生主體學(xué)習(xí)地位上下功夫，在落實每一個學(xué)生自主學(xué)習(xí)上下功夫，在落實學(xué)生合作學(xué)習(xí)上下功夫，在充分調(diào)動每一個學(xué)生的學(xué)習(xí)積極性上下功夫，在防止學(xué)生的學(xué)習(xí)活動流于形式、切實提高課堂效益上下功夫。因此教師教學(xué)設(shè)計已升華為教師教學(xué)研究的一個重要內(nèi)容。那么如何教學(xué)設(shè)計呢？應(yīng)從以下幾方面考慮：
一、準(zhǔn)確定位學(xué)生學(xué)習(xí)目標(biāo)，保底目標(biāo)和開放目標(biāo)并重
幫助學(xué)生決定適當(dāng)?shù)膶W(xué)習(xí)目標(biāo)，并確認和協(xié)調(diào)達到目標(biāo)的最佳途徑，是教師作為學(xué)生學(xué)習(xí)的促進者的重要任務(wù)之一。傳統(tǒng)教學(xué)設(shè)計中的目標(biāo)確定是一種知識的預(yù)設(shè)。新課堂的特征具有開放性，要求達成學(xué)生知識與能力、過程與方法及情感、態(tài)度、價值觀三維目標(biāo)。目標(biāo)設(shè)計上要做到“三個并重”。即保底目標(biāo)和開放目標(biāo)并重，顯性目標(biāo)和隱性目標(biāo)并重，短期目標(biāo)和長期目標(biāo)并重。保底目標(biāo)、顯性目標(biāo)、短期目標(biāo)可理解為本課和本單元知識、能力點要求，從這個角度說，傳統(tǒng)的知識點、能力點要求仍然是教師教學(xué)設(shè)計中必須重視的。開放目標(biāo)、隱性目標(biāo)、長期目標(biāo)可以理解。一是：過程和方法的考慮，必須重視設(shè)計每個學(xué)生自主思索的平臺，必須讓每個學(xué)生都能用語文的方法思考問題、解決問題；二是：可理解為看不
見的方法、情感、態(tài)度、價值觀要求，主要表現(xiàn)為培養(yǎng)學(xué)生熱愛科學(xué)、勤于思考、善于探索、長于合作、追求真理的學(xué)習(xí)心理和學(xué)習(xí)品質(zhì)。教學(xué)設(shè)計中應(yīng)考慮兩項內(nèi)容：一是：本課的保底目標(biāo)、短期目標(biāo)或顯性目標(biāo)。這里主要考慮的是知識點和能力點的“保底”問題，許多教師怕新課程的“放”，擔(dān)心的是失去音樂的“命根”，足見“保底”的重要性。一節(jié)課的學(xué)習(xí)，保底目標(biāo)、短期目標(biāo)或顯性目標(biāo)如何定位，怎樣實現(xiàn)這個目標(biāo)，教師應(yīng)該根據(jù)單元學(xué)習(xí)目標(biāo)、自讀提示、課后練習(xí)及三者之間的內(nèi)在聯(lián)系來決定。一般來說教學(xué)方面落實教材安排的思考練習(xí)內(nèi)容就可以了，因為那是經(jīng)過專家研究的一種精心編排，自然具有很強的科學(xué)性，不必要去展開，去拔高。應(yīng)該首先確定本課元素積累、知識積累和情感的方法準(zhǔn)確是考慮學(xué)生積極主動學(xué)習(xí)、積極主動參與合作、積極主動參與交流等開放性、隱蔽性、長期性目標(biāo)，促進學(xué)生積極參與到學(xué)習(xí)過程中來，培養(yǎng)積極的情感、態(tài)度和正確的價值觀。
二、改變課堂結(jié)構(gòu)，化教師講授為學(xué)生學(xué)習(xí)活動
新課程理念認為，課程是經(jīng)驗，課程是人類已有經(jīng)驗和教師、學(xué)生個人生活經(jīng)驗的結(jié)合，因而新課程強調(diào)，教學(xué)是教師與學(xué)生間、學(xué)生與學(xué)生間的交流、互動的過程。在這里師生之間、學(xué)生與學(xué)生之間分享彼此的思考、經(jīng)驗和知識，交流彼此的情感、體驗與觀念，在這種交流中生成新的知識，求得新的發(fā)展。所以，教學(xué)設(shè)計的第一要務(wù)是安排學(xué)習(xí)活動。設(shè)計學(xué)習(xí)活動的方法有三。一是常規(guī)法，二是挖掘教材或練習(xí)內(nèi)涵，靈活設(shè)計活動，盡可能地尋找學(xué)生活動的載體。第三，咬文嚼字，多向思維，給足學(xué)生自由思考的空間，充分安排學(xué)生質(zhì)疑的活動環(huán)節(jié)，鼓勵學(xué)生積極大膽
思考問題，促進新知識的生成。教師要想多說也不行，只能做導(dǎo)演。
三、做好組織和引導(dǎo)工作，落實合作和網(wǎng)狀學(xué)習(xí)
要保證學(xué)習(xí)活動不流于形式，保證課堂學(xué)習(xí)交流的效率，教師的組織和引導(dǎo)工作非常重要。一要合理分工，以實現(xiàn)合作，尤其是學(xué)習(xí)內(nèi)容較豐富的學(xué)習(xí)活動。
四、課前預(yù)案與課中記錄、調(diào)適及課后反思相結(jié)合
傳統(tǒng)的教學(xué)設(shè)計是施教前的精心設(shè)計，一旦物化為教案，就一勞永逸，反復(fù)使用。按新課程標(biāo)準(zhǔn)來看，完整的教學(xué)設(shè)計應(yīng)該是教學(xué)前的預(yù)案加教學(xué)中的記錄、調(diào)適加教學(xué)后的反思。預(yù)案設(shè)計宜粗不宜細，只需設(shè)計話題、設(shè)計活動板塊、設(shè)計主問題，只為學(xué)生“自主、合作、探究”的學(xué)習(xí)提供平臺。
教學(xué)設(shè)計的精華在于教學(xué)中的記錄、調(diào)適，教學(xué)中，有時候?qū)W生的行為并沒有按教師的設(shè)計意圖來進行，教師要觀察、傾聽，了解學(xué)生的原始理解，發(fā)現(xiàn)富有創(chuàng)意的閃光點，從而調(diào)整教學(xué)目標(biāo)、教學(xué)問題、教學(xué)流程，完成第二次教學(xué)設(shè)計。此時，不能讓活人圍繞死的教案轉(zhuǎn)，要在調(diào)整中獲得新的發(fā)展，在超越預(yù)定目標(biāo)中獲得創(chuàng)新。所以教學(xué)設(shè)計不能是定案，只能是預(yù)案。預(yù)案調(diào)適的原則，不是老師牽著學(xué)生走，而是學(xué)生思維推著老師走，使學(xué)生的個性得到充分、自由發(fā)展。老師既不能扼制學(xué)生的看法，又不能擱置學(xué)生的問題，而是順著學(xué)生的思維探究下去，時時刻刻都體現(xiàn)“心中有人”的教學(xué)理念。

Lesson Plan Presentation
Reading Part in NSEFC Module 1 Unit1 Friendship——Anne’s Best Friend
Hello, everyone. I’m …. I’m very glad to be here to present my lesson plan. The lesson I’m going to talk about is the reading in NSEFC module 1 Unit1 Friendship. The title of the reading material is Anne’s Best Friend. I will present how to teach it and the reasons for doing so in the following aspects: the analyses of teaching material and learning condition, teaching objectives，the important and difficult points, teaching method, teaching procedures and blackboard notes.
First of all, I’d like to analyze the teaching material. The text is about the story of a Jewish girl who treated her diary as her best friend when she was hiding away from the Nazi during the Second World War. It mainly consists of two parts; the first part is the introduction of Anne and her diary named Kitty. The second part is a diary entry written by Anne in the form of letter addressed to Kitty. The text is a bit long and there are a lot of new words and expressions in it, especially in the letter.
Now, let’s move on to the analysis of learning conditions. The students are in grade1 in the senior school, they have achieved certain English level so they have no problem in comprehending the text and get the basic idea. They have learned the Second World War so their previous knowledge about it can lessen their difficulty of comprehension. But most of them maybe are not very familiar with the sufferings of the Jewish people during the war. I will introduce the related information rightly in the beginning of the lesson so as to prepare the students for the deep study of the text.
Based on the analyses of the teaching material and the learning condition, I’d like to propose the teaching objectives and the important and difficult points.
(1) language skill
Ss will improve their reading skills by training some of the reading skills, such as skimming, scanning. It is the important point of this lesson.
Ss will improve their writing skills by writing a letter to their friend. It is the difficult point of this lesson.
(2) language knowledge
Ss will master most of the new words and expressions in the text. This is the important point of this lesson.
Ss will know the direct speech and indirect speech.
(3) Affective objectives
Ss will have a deeper understanding of the friendship so they will cherish their friends more than ever before. Ss will realize the cruelty of the war and the importance of the peace.
(4) Culture awareness
Ss will know more about the Second World War, especially the persecution Jewish people suffered from the Nazi.
(5) Learning strategy
Ss will cultivate their ability of individual learning and cooperative learning.
As for the teaching methods, I mainly adopt audio-visual teaching method in the lead-in. During the reading process, I follow the top down modal to help the Ss to learn the text.
Now, here comes the most important part of my presentation—teaching procedures. I’ll finish the lesson in 4 steps within 45 minutes. They are:
Step1: Lead-in.
Step2:Pre-reading
Step3: While reading.
Step 4: Post-reading.
At the end of the lesson, I will present the homework.
Now, let me introduce them step by step in details.
The first step is lead-in. It will cost 7minutes. At the beginning of the lesson, I will play a short video clip which is about the sufferings of the Jewish people during the Second World War. From it, Ss will know that many Jewish people were caught and killed by Nazi in the camps, so others had to hide away. Then I will ask Ss what they needed most when in hiding. Ss may come up with the food, clothes and so on. I will give them some hint and they will realize that friends are also very important for them. Then it will be very natural for me to tell them than there was a girl called Anne who had a very good friend during the hard time. In this process, I will introduce them three new words, they are: German, Netherlands, go through. In this step, I adopt audio-visual teaching method, because the pictures and sounds serves better to activate the Ss. So I use the video to attract the Ss’ attention. What’s more, the introduction of Jewish people’s suffering by this video clip provides them with the background information of this text.
Then I will move on to the second step---pre-reading. It will only cost 3 minutes. The Ss are required to guess who Anne’s best friend is and what happened to them by looking at the title and the pictures. Then I will ask several Ss to say their predictions but I will not tell them the answer directly in this step. Although not all the Ss can get the right answer, their mind can get closer to the theme of the text by predicting. So, later, when they read the passage they will concentrate more on it to check their predictions.
After pre-reading, we will move on to the while-reading step which costs 22 minutes in total. There are 5 activities, the first three of which deals with the first two paragraphs of the text which is also the first part of the text. And the last two activities deal with the second part.
The first activity is skimming. Ss are expected to skim the first part of text to work out the main idea. But as there is no topic sentence in this part, it is a bit difficult for students to tell the main idea with their own words. So I will present a multiple choice which covers the main idea of the text for them to choose from. This reduces the difficulty of the task as well as the Ss’ anxiety.
After getting the main idea, we will do another activity, namely, scanning. Ss are expected to scan the text to find some specific information, such as the place and the time of the story, etc. Ss can develop the ability of information gathering and independent learning.
After skimming and scanning, we will do the third activity of this step---close reading. I will help Ss learn the passage paragraph by paragraph. For the first paragraph, I will ask some questions like “According to Anne, what kind of person should a true friend be?” The answer to these questions cannot be taken directly from the text. Ss need to reorganize the sentences. If they can answer these questions, it means they have understood this paragraph. Then we will learn the second paragraph. For this one, I will ask one question “What did Anne say about her diary?” Ss may answer it by the original words said by Anne, I will catch this opportunity to tell them they change the direct speech into the indirect speech. But I will not go deeper, because they will learn this language point next period, so a simple introduction is ok.
This is all for the first part of the text. Then we will start to learn the letter. There are two activities for this part. The first one is skimming，they should skim the letter for the main idea first and I will present a multiple choice for them to choose from. Them we will learn the letter in detail in the next activity. For the first paragraph of the letter, I will ask them to find out the changing of Anne’s attitudes toward nature. Ss can find out that before hiding away, she paid no attention to the nature while she grew crazy about it when hiding. Then I will ask them to find out the reason. As for the second paragraph, Anne narrates two experiences of longing to get close to nature. So firstly, I will ask them to pick out the time of the experience and then we will study her feelings in the process. Of cause, we will learn some new word here, such as on purpose, at dusk and so on.
After the while-reading, comes the post-reading step. It will cost 12 minutes. In this step, I will firstly ask Ss if they have to go into hiding like Anne and her family, what they would like to say to their friends. Ss will talk in groups of four and share their ideas with each other. During the discussion, the Ss will be stimulated and also know the importance of friendship. It servers to make the Ss be prepared for the next activity---writing. After the discussion, the Ss shall write a letter to their friends individually. As they have talked about what they want to say to their friends, the difficulty of the writing is lowered because they have something to say. Ss are expected to write just a draft, for the time is limited.
Lastly, I will give Ss the homework. It will only cost one minute. Ss should not only review the new words and expressions of the text, but also polish their letter after class.
That’s all for the teaching procedure. And here is my blackboard note. On the right side, there are the words and expressions. In the middle, there are some points of the comprehension of the text.
That all for my lesson plan presentation thanks for your attention.

[教學(xué)目標(biāo)]
1、在具體的情境中，進一步認識分數(shù)，發(fā)展學(xué)生的數(shù)感，體會數(shù)學(xué)與生活的密切聯(lián)系。
2、.通過對分數(shù)的意義的理解，結(jié)合具體的情境，體會整體與部分的關(guān)系。培養(yǎng)學(xué)生觀察、抽象、概括、類推的能力。
[教學(xué)重、難點]
理解并掌握分數(shù)的意義。
單位“1”概念的擴展。
[教學(xué)過程]
一、拿鉛筆。
1、現(xiàn)場組織活動：請兩位同學(xué)到臺前來，每人分別從一盒鉛筆中拿出 ，結(jié)果兩位學(xué)生拿得不一樣多，一位學(xué)生拿出4枝，另一位學(xué)生拿出3枝。
2、思考問題：他們兩人都是拿了鉛筆的 ，拿出的鉛筆枝數(shù)卻不一樣多，這是為什么？請想一想，然后小組交流。
3、在班里進行反饋。引導(dǎo)學(xué)生發(fā)現(xiàn)兩盒鉛筆的總枝數(shù)不同，也就是整體“1”不一樣了。
4、師生共同小結(jié)：一盒鉛筆的 表示的都是把一盒鉛筆平均分成2份，其中的一份就是 。但由于分數(shù)所對應(yīng)的整體不同，所以 表示的具體數(shù)量也不一樣了。
二、說一說。
出示書中的情境圖：
聯(lián)系一本書的 ，一塊蛋糕的 等實際情境展開交流，體會一個分數(shù)對應(yīng)的整體不同，所表示的具體數(shù)量也不同，進一步加深學(xué)生對分數(shù)的認識。
三、畫一畫。
一個圖形的 是□，請學(xué)生畫出這個圖形。然后組織學(xué)生進行交流。借助直觀圖形體會一個圖形的 都是一個□，但是這個圖形的形狀可能不同。
四、練一練。
第1題：用分數(shù)表示下面各圖中的涂色部分。先讓學(xué)生獨立填寫，然后選擇其中幾題讓學(xué)生說說思考的過程。
第2題：請在圖中用顏色表示各個分數(shù)。學(xué)生獨立完成。
第3題：請分別畫出下列各個圖形的 ，它們的大小一樣嗎？
第4題：結(jié)合“捐零花錢”的實際問題，體會分數(shù)的相對性。讓學(xué)生說說自己的想法，可以舉例說明。

英語站課件(篇3)
設(shè)計好教學(xué)設(shè)計是上好課的先決條件。在新課程條件下，隨著教師角色的轉(zhuǎn)變和學(xué)生學(xué)習(xí)方式的改變的要求，教學(xué)設(shè)計不再是教材內(nèi)容的簡單的詮釋、教學(xué)過程的簡單的安排、教學(xué)方法的簡單的展示，它的性質(zhì)、功能、方法已經(jīng)發(fā)生了很大的變化。它要求教師從新課程理念出發(fā)，在落實學(xué)生主體學(xué)習(xí)地位上下功夫，在落實每一個學(xué)生自主學(xué)習(xí)上下功夫，在落實學(xué)生合作學(xué)習(xí)上下功夫，在充分調(diào)動每一個學(xué)生的學(xué)習(xí)積極性上下功夫，在防止學(xué)生的學(xué)習(xí)活動流于形式、切實提高課堂效益上下功夫。因此教師教學(xué)設(shè)計已升華為教師教學(xué)研究的一個重要內(nèi)容。那么如何教學(xué)設(shè)計呢？應(yīng)從以下幾方面考慮：
一、準(zhǔn)確定位學(xué)生學(xué)習(xí)目標(biāo)，保底目標(biāo)和開放目標(biāo)并重
幫助學(xué)生決定適當(dāng)?shù)膶W(xué)習(xí)目標(biāo)，并確認和協(xié)調(diào)達到目標(biāo)的最佳途徑，是教師作為學(xué)生學(xué)習(xí)的促進者的重要任務(wù)之一。傳統(tǒng)教學(xué)設(shè)計中的目標(biāo)確定是一種知識的預(yù)設(shè)。新課堂的特征具有開放性，要求達成學(xué)生知識與能力、過程與方法及情感、態(tài)度、價值觀三維目標(biāo)。目標(biāo)設(shè)計上要做到“三個并重”。即保底目標(biāo)和開放目標(biāo)并重，顯性目標(biāo)和隱性目標(biāo)并重，短期目標(biāo)和長期目標(biāo)并重。保底目標(biāo)、顯性目標(biāo)、短期目標(biāo)可理解為本課和本單元知識、能力點要求，從這個角度說，傳統(tǒng)的知識點、能力點要求仍然是教師教學(xué)設(shè)計中必須重視的。開放目標(biāo)、隱性目標(biāo)、長期目標(biāo)可以理解。一是：過程和方法的考慮，必須重視設(shè)計每個學(xué)生自主思索的平臺，必須讓每個學(xué)生都能用語文的方法思考問題、解決問題；二是：可理解為看不
見的方法、情感、態(tài)度、價值觀要求，主要表現(xiàn)為培養(yǎng)學(xué)生熱愛科學(xué)、勤于思考、善于探索、長于合作、追求真理的學(xué)習(xí)心理和學(xué)習(xí)品質(zhì)。教學(xué)設(shè)計中應(yīng)考慮兩項內(nèi)容：一是：本課的保底目標(biāo)、短期目標(biāo)或顯性目標(biāo)。這里主要考慮的是知識點和能力點的“保底”問題，許多教師怕新課程的“放”，擔(dān)心的是失去音樂的“命根”，足見“保底”的重要性。一節(jié)課的學(xué)習(xí)，保底目標(biāo)、短期目標(biāo)或顯性目標(biāo)如何定位，怎樣實現(xiàn)這個目標(biāo)，教師應(yīng)該根據(jù)單元學(xué)習(xí)目標(biāo)、自讀提示、課后練習(xí)及三者之間的內(nèi)在聯(lián)系來決定。一般來說教學(xué)方面落實教材安排的思考練習(xí)內(nèi)容就可以了，因為那是經(jīng)過專家研究的一種精心編排，自然具有很強的科學(xué)性，不必要去展開，去拔高。應(yīng)該首先確定本課元素積累、知識積累和情感的方法準(zhǔn)確是考慮學(xué)生積極主動學(xué)習(xí)、積極主動參與合作、積極主動參與交流等開放性、隱蔽性、長期性目標(biāo)，促進學(xué)生積極參與到學(xué)習(xí)過程中來，培養(yǎng)積極的情感、態(tài)度和正確的價值觀。
二、改變課堂結(jié)構(gòu)，化教師講授為學(xué)生學(xué)習(xí)活動
新課程理念認為，課程是經(jīng)驗，課程是人類已有經(jīng)驗和教師、學(xué)生個人生活經(jīng)驗的結(jié)合，因而新課程強調(diào)，教學(xué)是教師與學(xué)生間、學(xué)生與學(xué)生間的交流、互動的過程。在這里師生之間、學(xué)生與學(xué)生之間分享彼此的思考、經(jīng)驗和知識，交流彼此的情感、體驗與觀念，在這種交流中生成新的知識，求得新的發(fā)展。所以，教學(xué)設(shè)計的第一要務(wù)是安排學(xué)習(xí)活動。設(shè)計學(xué)習(xí)活動的方法有三。一是常規(guī)法，二是挖掘教材或練習(xí)內(nèi)涵，靈活設(shè)計活動，盡可能地尋找學(xué)生活動的載體。第三，咬文嚼字，多向思維，給足學(xué)生自由思考的空間，充分安排學(xué)生質(zhì)疑的活動環(huán)節(jié)，鼓勵學(xué)生積極大膽
思考問題，促進新知識的生成。教師要想多說也不行，只能做導(dǎo)演。
三、做好組織和引導(dǎo)工作，落實合作和網(wǎng)狀學(xué)習(xí)
要保證學(xué)習(xí)活動不流于形式，保證課堂學(xué)習(xí)交流的效率，教師的組織和引導(dǎo)工作非常重要。一要合理分工，以實現(xiàn)合作，尤其是學(xué)習(xí)內(nèi)容較豐富的學(xué)習(xí)活動。
四、課前預(yù)案與課中記錄、調(diào)適及課后反思相結(jié)合
傳統(tǒng)的教學(xué)設(shè)計是施教前的精心設(shè)計，一旦物化為教案，就一勞永逸，反復(fù)使用。按新課程標(biāo)準(zhǔn)來看，完整的教學(xué)設(shè)計應(yīng)該是教學(xué)前的預(yù)案加教學(xué)中的記錄、調(diào)適加教學(xué)后的反思。預(yù)案設(shè)計宜粗不宜細，只需設(shè)計話題、設(shè)計活動板塊、設(shè)計主問題，只為學(xué)生“自主、合作、探究”的學(xué)習(xí)提供平臺。
教學(xué)設(shè)計的精華在于教學(xué)中的記錄、調(diào)適，教學(xué)中，有時候?qū)W生的行為并沒有按教師的設(shè)計意圖來進行，教師要觀察、傾聽，了解學(xué)生的原始理解，發(fā)現(xiàn)富有創(chuàng)意的閃光點，從而調(diào)整教學(xué)目標(biāo)、教學(xué)問題、教學(xué)流程，完成第二次教學(xué)設(shè)計。此時，不能讓活人圍繞死的教案轉(zhuǎn)，要在調(diào)整中獲得新的發(fā)展，在超越預(yù)定目標(biāo)中獲得創(chuàng)新。所以教學(xué)設(shè)計不能是定案，只能是預(yù)案。預(yù)案調(diào)適的原則，不是老師牽著學(xué)生走，而是學(xué)生思維推著老師走，使學(xué)生的個性得到充分、自由發(fā)展。老師既不能扼制學(xué)生的看法，又不能擱置學(xué)生的問題，而是順著學(xué)生的思維探究下去，時時刻刻都體現(xiàn)“心中有人”的教學(xué)理念。

Lesson Plan Presentation
Reading Part in NSEFC Module 1 Unit1 Friendship——Anne’s Best Friend
Hello, everyone. I’m …. I’m very glad to be here to present my lesson plan. The lesson I’m going to talk about is the reading in NSEFC module 1 Unit1 Friendship. The title of the reading material is Anne’s Best Friend. I will present how to teach it and the reasons for doing so in the following aspects: the analyses of teaching material and learning condition, teaching objectives，the important and difficult points, teaching method, teaching procedures and blackboard notes.
First of all, I’d like to analyze the teaching material. The text is about the story of a Jewish girl who treated her diary as her best friend when she was hiding away from the Nazi during the Second World War. It mainly consists of two parts; the first part is the introduction of Anne and her diary named Kitty. The second part is a diary entry written by Anne in the form of letter addressed to Kitty. The text is a bit long and there are a lot of new words and expressions in it, especially in the letter.
Now, let’s move on to the analysis of learning conditions. The students are in grade1 in the senior school, they have achieved certain English level so they have no problem in comprehending the text and get the basic idea. They have learned the Second World War so their previous knowledge about it can lessen their difficulty of comprehension. But most of them maybe are not very familiar with the sufferings of the Jewish people during the war. I will introduce the related information rightly in the beginning of the lesson so as to prepare the students for the deep study of the text.
Based on the analyses of the teaching material and the learning condition, I’d like to propose the teaching objectives and the important and difficult points.
(1) language skill
Ss will improve their reading skills by training some of the reading skills, such as skimming, scanning. It is the important point of this lesson.
Ss will improve their writing skills by writing a letter to their friend. It is the difficult point of this lesson.
(2) language knowledge
Ss will master most of the new words and expressions in the text. This is the important point of this lesson.
Ss will know the direct speech and indirect speech.
(3) Affective objectives
Ss will have a deeper understanding of the friendship so they will cherish their friends more than ever before. Ss will realize the cruelty of the war and the importance of the peace.
(4) Culture awareness
Ss will know more about the Second World War, especially the persecution Jewish people suffered from the Nazi.
(5) Learning strategy
Ss will cultivate their ability of individual learning and cooperative learning.
As for the teaching methods, I mainly adopt audio-visual teaching method in the lead-in. During the reading process, I follow the top down modal to help the Ss to learn the text.
Now, here comes the most important part of my presentation—teaching procedures. I’ll finish the lesson in 4 steps within 45 minutes. They are:
Step1: Lead-in.
Step2:Pre-reading
Step3: While reading.
Step 4: Post-reading.
At the end of the lesson, I will present the homework.
Now, let me introduce them step by step in details.
The first step is lead-in. It will cost 7minutes. At the beginning of the lesson, I will play a short video clip which is about the sufferings of the Jewish people during the Second World War. From it, Ss will know that many Jewish people were caught and killed by Nazi in the camps, so others had to hide away. Then I will ask Ss what they needed most when in hiding. Ss may come up with the food, clothes and so on. I will give them some hint and they will realize that friends are also very important for them. Then it will be very natural for me to tell them than there was a girl called Anne who had a very good friend during the hard time. In this process, I will introduce them three new words, they are: German, Netherlands, go through. In this step, I adopt audio-visual teaching method, because the pictures and sounds serves better to activate the Ss. So I use the video to attract the Ss’ attention. What’s more, the introduction of Jewish people’s suffering by this video clip provides them with the background information of this text.
Then I will move on to the second step---pre-reading. It will only cost 3 minutes. The Ss are required to guess who Anne’s best friend is and what happened to them by looking at the title and the pictures. Then I will ask several Ss to say their predictions but I will not tell them the answer directly in this step. Although not all the Ss can get the right answer, their mind can get closer to the theme of the text by predicting. So, later, when they read the passage they will concentrate more on it to check their predictions.
After pre-reading, we will move on to the while-reading step which costs 22 minutes in total. There are 5 activities, the first three of which deals with the first two paragraphs of the text which is also the first part of the text. And the last two activities deal with the second part.
The first activity is skimming. Ss are expected to skim the first part of text to work out the main idea. But as there is no topic sentence in this part, it is a bit difficult for students to tell the main idea with their own words. So I will present a multiple choice which covers the main idea of the text for them to choose from. This reduces the difficulty of the task as well as the Ss’ anxiety.
After getting the main idea, we will do another activity, namely, scanning. Ss are expected to scan the text to find some specific information, such as the place and the time of the story, etc. Ss can develop the ability of information gathering and independent learning.
After skimming and scanning, we will do the third activity of this step---close reading. I will help Ss learn the passage paragraph by paragraph. For the first paragraph, I will ask some questions like “According to Anne, what kind of person should a true friend be?” The answer to these questions cannot be taken directly from the text. Ss need to reorganize the sentences. If they can answer these questions, it means they have understood this paragraph. Then we will learn the second paragraph. For this one, I will ask one question “What did Anne say about her diary?” Ss may answer it by the original words said by Anne, I will catch this opportunity to tell them they change the direct speech into the indirect speech. But I will not go deeper, because they will learn this language point next period, so a simple introduction is ok.
This is all for the first part of the text. Then we will start to learn the letter. There are two activities for this part. The first one is skimming，they should skim the letter for the main idea first and I will present a multiple choice for them to choose from. Them we will learn the letter in detail in the next activity. For the first paragraph of the letter, I will ask them to find out the changing of Anne’s attitudes toward nature. Ss can find out that before hiding away, she paid no attention to the nature while she grew crazy about it when hiding. Then I will ask them to find out the reason. As for the second paragraph, Anne narrates two experiences of longing to get close to nature. So firstly, I will ask them to pick out the time of the experience and then we will study her feelings in the process. Of cause, we will learn some new word here, such as on purpose, at dusk and so on.
After the while-reading, comes the post-reading step. It will cost 12 minutes. In this step, I will firstly ask Ss if they have to go into hiding like Anne and her family, what they would like to say to their friends. Ss will talk in groups of four and share their ideas with each other. During the discussion, the Ss will be stimulated and also know the importance of friendship. It servers to make the Ss be prepared for the next activity---writing. After the discussion, the Ss shall write a letter to their friends individually. As they have talked about what they want to say to their friends, the difficulty of the writing is lowered because they have something to say. Ss are expected to write just a draft, for the time is limited.
Lastly, I will give Ss the homework. It will only cost one minute. Ss should not only review the new words and expressions of the text, but also polish their letter after class.
That’s all for the teaching procedure. And here is my blackboard note. On the right side, there are the words and expressions. In the middle, there are some points of the comprehension of the text.
That all for my lesson plan presentation thanks for your attention.

[教學(xué)目標(biāo)]
1、在具體的情境中，進一步認識分數(shù)，發(fā)展學(xué)生的數(shù)感，體會數(shù)學(xué)與生活的密切聯(lián)系。
2、.通過對分數(shù)的意義的理解，結(jié)合具體的情境，體會整體與部分的關(guān)系。培養(yǎng)學(xué)生觀察、抽象、概括、類推的能力。
[教學(xué)重、難點]
理解并掌握分數(shù)的意義。
單位“1”概念的擴展。
[教學(xué)過程]
一、拿鉛筆。
1、現(xiàn)場組織活動：請兩位同學(xué)到臺前來，每人分別從一盒鉛筆中拿出 ，結(jié)果兩位學(xué)生拿得不一樣多，一位學(xué)生拿出4枝，另一位學(xué)生拿出3枝。
2、思考問題：他們兩人都是拿了鉛筆的 ，拿出的鉛筆枝數(shù)卻不一樣多，這是為什么？請想一想，然后小組交流。
3、在班里進行反饋。引導(dǎo)學(xué)生發(fā)現(xiàn)兩盒鉛筆的總枝數(shù)不同，也就是整體“1”不一樣了。
4、師生共同小結(jié)：一盒鉛筆的 表示的都是把一盒鉛筆平均分成2份，其中的一份就是 。但由于分數(shù)所對應(yīng)的整體不同，所以 表示的具體數(shù)量也不一樣了。
二、說一說。
出示書中的情境圖：
聯(lián)系一本書的 ，一塊蛋糕的 等實際情境展開交流，體會一個分數(shù)對應(yīng)的整體不同，所表示的具體數(shù)量也不同，進一步加深學(xué)生對分數(shù)的認識。
三、畫一畫。
一個圖形的 是□，請學(xué)生畫出這個圖形。然后組織學(xué)生進行交流。借助直觀圖形體會一個圖形的 都是一個□，但是這個圖形的形狀可能不同。
四、練一練。
第1題：用分數(shù)表示下面各圖中的涂色部分。先讓學(xué)生獨立填寫，然后選擇其中幾題讓學(xué)生說說思考的過程。
第2題：請在圖中用顏色表示各個分數(shù)。學(xué)生獨立完成。
