(一)教材的地位與作用教材的第一部分就從地質(zhì)作用的能量來源的角度,講述了內(nèi)力作用和外力作用及其表現(xiàn)形式;又以地質(zhì)作用不同的表現(xiàn)形式,來說明了激烈迅速的地質(zhì)作用和極其緩慢的地質(zhì)作用,從而使學(xué)生理解地表形態(tài)的變化及這種變化的時(shí)間尺度。第二部分,從三大類巖石的相互轉(zhuǎn)變?nèi)胧郑瑘D文結(jié)合,闡明了在內(nèi)外力作用的參與下地殼物質(zhì)循環(huán)的過程及其地理意義,該部分內(nèi)容可以看作是全課教材的小結(jié)。(二)教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo):1、結(jié)合實(shí)例,說明內(nèi)力作用的能量來源及其表現(xiàn)形式,理解地殼運(yùn)動(dòng)是塑造地表形態(tài)的主要作用方式。2、說明外力作用的四種形式及其相互關(guān)系,嘗試識(shí)別外力作用形成的不同地貌。3、會(huì)用圖文資料說明地殼物質(zhì)循環(huán)的過程及其產(chǎn)生循環(huán)的物質(zhì)基礎(chǔ)——三大類巖石的轉(zhuǎn)化過程。4、培養(yǎng)學(xué)生運(yùn)用地理圖表分析歸納的能力,培養(yǎng)學(xué)生與其它同學(xué)交流、表達(dá)的能力。

(一)教材的地位與作用教材第一部分的順序是:先給學(xué)生洋流的概念以及洋流按照性質(zhì)的分類,接著說明洋流的主要成因與盛行風(fēng)有關(guān)。并結(jié)合風(fēng)帶與洋流模式圖總結(jié)和歸納了洋流的分布規(guī)律。最后,給出世界表層洋流的冬季分布圖,讓學(xué)生讀圖思考的問題主要涉及洋流的分布規(guī)律和原因。教材第二部分闡述了洋流對(duì)地理環(huán)境四個(gè)方面的影響。教材的順序和要求與課標(biāo)要求、學(xué)生認(rèn)知規(guī)律有矛盾的地方,需要重組教學(xué)的順序——先由洋流對(duì)地理環(huán)境和人類活動(dòng)的影響的例子來設(shè)置懸念,激發(fā)學(xué)生認(rèn)識(shí)的欲望,提供材料歸納世界表層洋流的分布規(guī)律,再探究其主要驅(qū)動(dòng)力。(二)教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo):①運(yùn)用地圖,從分布位置、運(yùn)動(dòng)方向、寒暖流的位置來歸納世界表層洋流的分布規(guī)律②畫出世界表層洋流的分布簡(jiǎn)單模式圖③掌握洋流的主要成因

(一)教材的地位與作用第一部分的內(nèi)容——山岳的形成,教材首先指出山岳的形成和內(nèi)力作用關(guān)系密切,然后對(duì)褶皺山、斷塊山和火山的成因、基本形態(tài)特征和規(guī)模進(jìn)行分析。由于褶皺山和斷塊山是形成于一定的地質(zhì)構(gòu)造上的,所以教材在講述這兩種山岳的形成時(shí),都先從褶皺和斷層這兩種最基本的地質(zhì)構(gòu)造開始講起,并且教材還配以閱讀材料和活動(dòng)題來幫助學(xué)生更好地掌握這部分內(nèi)容。第二部分的內(nèi)容——山岳對(duì)交通的影響,教材主要分析了山岳對(duì)交通三方面的影響:對(duì)運(yùn)輸線路結(jié)構(gòu)、對(duì)線路分布格局和線路延伸方向的影響,并且設(shè)計(jì)了相應(yīng)的活動(dòng)題幫助學(xué)生理解。(二)教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo):1.了解褶皺的概念和基本形態(tài),掌握正確判斷背斜和向斜的方法,理解褶皺山的概念。2.了解斷層的概念,掌握斷層對(duì)地表形態(tài)的影響,理解斷塊山的概念。3.了解火山的形成過程,掌握火山的組成。

二、說學(xué)情學(xué)生對(duì)自然界中的水循環(huán)已具有一定的生活體驗(yàn)和知識(shí)基礎(chǔ),主要問題是學(xué)生還未上升到理性的層面上進(jìn)行分析,而且自然界的水循環(huán)屬于全球尺度和大尺度的地理現(xiàn)象,學(xué)生難以理解,需要教師創(chuàng)設(shè)適當(dāng)?shù)那榫骋龑?dǎo)學(xué)生進(jìn)行新知的建構(gòu)。三、說教法(1)創(chuàng)設(shè)情景:教學(xué)實(shí)踐證明,合理有趣的情境創(chuàng)設(shè),可以引導(dǎo)學(xué)生快速進(jìn)入角色,提高課堂效率(2)討論法:通過組織學(xué)生討論,給學(xué)生提供自主學(xué)習(xí)、合作學(xué)習(xí)、探究學(xué)習(xí)的機(jī)會(huì)。(3)多媒體演示法:利用多媒體播放一些直觀的圖片、動(dòng)畫和數(shù)字資料,把學(xué)生輕松得引入本課,通過形象生動(dòng)直觀地展現(xiàn)相關(guān)地理事物和現(xiàn)象,提高學(xué)生的感性認(rèn)識(shí),激發(fā)興奮點(diǎn),幫助他們理解課本內(nèi)容。四、說學(xué)法(1)學(xué)會(huì)用圖:讓學(xué)生仔細(xì)觀察圖3.2和圖3.3理解水循環(huán)的相關(guān)性(2)學(xué)會(huì)探究:學(xué)生思考分析總結(jié)水循環(huán)的地理意義及黃河斷流的原因。

下面要針對(duì)工業(yè)地域內(nèi)部的工業(yè)聯(lián)系進(jìn)行講解,這里主要涉及到的是工序上的工業(yè)聯(lián)系。在這段文字的處理上,我會(huì)將鋼鐵、石化、機(jī)械加工等工業(yè)部門分散成一步一步的工序,便于學(xué)生理解這種工業(yè)上的聯(lián)系方式與構(gòu)造,進(jìn)而對(duì)于工業(yè)的發(fā)育程度這一概念的理解也就相對(duì)簡(jiǎn)單了。緊接著需要講述的是工業(yè)分散的內(nèi)容。工業(yè)分散是建立在現(xiàn)代的交通運(yùn)輸方式和通信技術(shù)與手段上的。它主要針對(duì)的是體積小、重量輕、價(jià)格昂貴的電子產(chǎn)品生產(chǎn)領(lǐng)域,目的是根據(jù)原件的不同性質(zhì)選擇不同的生產(chǎn)地域,利用其各異的優(yōu)勢(shì)條件以節(jié)省開支。由于案例都是針對(duì)高科技產(chǎn)品的生產(chǎn)而提出的,因此在這段教材的教學(xué)中我會(huì)注意避免將工業(yè)分散這一現(xiàn)象描述得更為高級(jí)。要讓學(xué)生明白,無論是工業(yè)集聚還是工業(yè)分散,它們之間是沒有好壞之分的。最后將進(jìn)行課堂小結(jié),由于本節(jié)內(nèi)容較少且相對(duì)簡(jiǎn)單,可以在最后適當(dāng)添加部分練習(xí)題,重點(diǎn)考察一二兩節(jié)的相關(guān)知識(shí)點(diǎn)。

Textbook: Senior English for China (Book 4), by Liu Daoyi Time Allotment: 1 period (40 minutes)Date: March 20, 2014Teaching aids: blackboard, Multi-media, Power Point, chalk I. Text Analysis (教材分析)This unit is about body language, and the text selected in the reading part demonstrates the difference and similarity of body language in many parts of the world. Through learning this passage, students are required to raise their awareness of using body language in different parts of the world. As body language is closely related to our daily life, it is easy to arouse students’ interest in learning this text. Reading skills and speaking training are designed around the text.II. Teaching Objectives (教學(xué)目標(biāo))By the end of the lesson, students will be able to:1. Language Skill Objective(語言技能目標(biāo)): develop reading ability (skimming and scanning)as well as speaking ability.2. Cultural Knowledge Objective(文化知識(shí)目標(biāo)): know about the cultural differences of using body language.3. Affective Objective(情感目標(biāo)): increase students’ awareness of using body language correctly in different cultures. III.Teaching Focuses and Difficulties(教學(xué)重點(diǎn)和難點(diǎn))1. Teaching Focuses(教學(xué)重點(diǎn)): the difference and similarity of body language in many parts of the world.2.

Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.

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

The oldest and the most popular park in the worldenjoy the exciting activities thereget close to the life-size cartoon characters like Mickey Mouse and Donald Duck Step 3 Pre-reading1.What do you suppose a theme park is ?2.What do you think you can see in a theme park?(1.It is a kind of amusement park which has a certain theme – that the whole park is based on. 2.buildings, castles, statues, rare animals and birds, and so on.) Step 4 Reading ----- Theme Parks –---- Fun and More Than Fun1.Predict : Read the title and the pictures on P. 34 and PredictWhat is the meaning of the title “Theme Park – Fun and more than fun”?(The title means that theme parks are fun to visit, but that they can also be educational and can offer useful information.)2.Skimming Fast read and answer:What activities can we take in a theme park?Amusement park: Bumper car Merry-go-round slide bungee jumping Free-fall rides Horror films Pirate ship Ferris wheel roller coaster3.Scanning Read again and you will find various theme parks are mentioned in the passage . Then what are they ?Theme parks: Sports theme park History theme park Culture theme park Marine or Ocean theme Park Future park Science theme park Disneyland4.Careful reading and find the main idea of each paragraph:THEME PARKS---- entertaining/ educationalPara.1 Traditional parks are places to go for relaxation and to have time away from our busy lives.Para.2 Theme parks are different They’re large and full of things to do, see and buy.Para.3 Theme parks are built around a single idea or theme. One example is a sports park.Para.4 Another kind of theme park is historical more and cultural and can be educational.Para.5 Disneylandwas the first theme park. It is based on the fantasy life and characters of Disney’s films.Para.6 Some examples of educational theme parks include sea world parks and science parks.

Language learning needs a context, which can help the learners to understand the language and then can product comprehensible output, so computer has the advantages to make the materials attractive.Part 3 Learning MethodsTask-based, self-dependent and cooperative learningPart 4 Teaching ProcedureStep One Lead-in“Interest is the best teacher.” Therefore, at the very beginning of the class, I should spark the students’ mind to focus on the centre topic “the band”. I’ll show some pictures of food to attract their attention and then bring some questions.Question:What kind of food they like?What should go into a good meal?The answers must relate to the diet. After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively. In addition, the task is to develop the students’ reading skill by making prediction and to encourage the students to express their thoughts in English and cooperate with each other.Task 2 Main idea of each paragraphCooperative learning can raise the students’ interest and create an atmosphere of achievement. Based on this theory, I divide the whole class into 4 groups to skim the whole text and get the main idea of each paragraph.

Knowledge objectives:(1) to make Ss grasp the usage of words, expressions and sentence structures: statistics, struggle, thanks to, rid of, some patterns for persuasion, the “ing” form as subject and object;(2)to use learnt knowledge to persuade sb.Ability objectives:(1) to develop Ss’ reading skills(skimming, scanning, word guessing);(2) to improve Ss’ speaking, communicating and cooperating skills.Emotional objectives:to make Ss know the contribution of Yuan,and learn his spirit and his simple life time.Teaching important and difficult points:(1) some words, expressions and sentence structures mentioned above;(2)the content of the text;(3)training their reading and speaking skills.Teaching methods: CLT, TBLT,QT.Learning strategies: CLS, QLS, TBLS.Teaching procedures:Step 1 lead-in: (1) teacher plays a piece of recent news from CCTV about the harvest of the super hybrid rice, and ask students whether they know Yuan or not, and talk about him and his contribution.(2)Brain storm: let Ss describe Yuan in their minds including his appearance, his living condition and so on.Step 2 fast reading tasks:(1)teacher introduces Yuan and super hybrid rice(2)make Ss read the text as fast as possible with questions.

通過寫文章梗概,培養(yǎng)學(xué)生綜合運(yùn)用語言的能力,學(xué)習(xí)用恰當(dāng)?shù)挠⒄Z描述科學(xué)家的故事。這是本課的教學(xué)難點(diǎn)。教師可以使用完形填空的方式來幫助學(xué)生整理語篇,從而來降低難度。本課的教學(xué)重點(diǎn)的突破方法是:在閱讀前,讓學(xué)生初步了解得出科學(xué)觀點(diǎn)所需要的基本程序,從而輕松而自然地導(dǎo)入文章的閱讀;在閱讀過程中,由易到難設(shè)計(jì)快速閱讀和精讀的問題,層層推進(jìn)各種閱讀活動(dòng),讓學(xué)生對(duì)閱讀內(nèi)容從整體感知到細(xì)節(jié)理解,最后深層讀懂整篇文章,同時(shí)加強(qiáng)閱讀策略的指導(dǎo),讓每個(gè)學(xué)生都主動(dòng)參與課堂教學(xué)活動(dòng),最終達(dá)到提高閱讀能力的目的。Step 4 Post-readingGroup Activities四人小組共同合作,在老師的適當(dāng)指導(dǎo)下,就以下2個(gè)問題展開討論,讓學(xué)生就所知、所學(xué)、所感和所想融入話題,然后抽若干同學(xué)代表作小組發(fā)言。1. What do you think about John Snow, and what should we learn from him?2. Cholera was 19th century disease, which two diseases are similar to cholera today? Why?

今天我們來介紹一下必修五第四單元的授課方式。這個(gè)單元的題目是Making the news。應(yīng)該是學(xué)生比較感興趣的話題,學(xué)生往往對(duì)新聞工作充滿好奇,所以我們可以利用這個(gè)機(jī)會(huì)多設(shè)計(jì)一些師生互動(dòng)和學(xué)生互動(dòng),來激發(fā)起學(xué)習(xí)的積極性,提高學(xué)習(xí)效率。同時(shí)我們可以利用這個(gè)單元不僅幫助學(xué)生掌握語言知識(shí),培養(yǎng)語言能力,同時(shí)讓其了解新聞工作的重要性,培養(yǎng)起社會(huì)智能感。這個(gè)單元分為六個(gè)課時(shí),它的教學(xué)目標(biāo)是這樣的:語言目標(biāo)是掌握詞匯表中的常用單詞和短語,掌握倒裝句的一些基本用法。 技能目標(biāo)是能初步掌握約會(huì)的基本句型并在真實(shí)的場(chǎng)景下正確運(yùn)用。新聞報(bào)道類文章的寫作技能。采訪的基本規(guī)范和溝通技能。情感目標(biāo)是對(duì)新聞報(bào)道的客觀性和真實(shí)性有更好的理解。對(duì)新聞?dòng)浾叩穆殬I(yè)有更深入的了解,并能體會(huì)其工作的重要性。下面我們來介紹一下第一課時(shí)的授課方式,第一課的教學(xué)目標(biāo)是這樣的第一課時(shí)的教學(xué)目標(biāo)語言目標(biāo):單詞:Occupation, journalist, editor, photographer, curious, personality, enthusiasm
