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.

In this class, I have 3 teaching aims, that is, knowledge aims, ability aims and emotion aims.1) Knowledge-Teach students new words and expressions, such as temporary, bleed,sprain choke, first aid, fall ill and so on.-Enable students to have a better understanding for some basic knowledge of first aid.2) Ability-Train students’ speaking, reading and writing abilities by different teaching activities, such as skimming, comprehending, team work, role play, retelling and writing.-Develop students’ reading strategy on how to move general idea to specific information.3) Emotion-Promote students’ awareness of giving first aid.- Cultivate students’ creativities.Then let’s come to my teaching methods and activities.III. Teaching methods and activities:To achieve different teaching aims, various kinds of teaching methods and activities will be adopted throughout this period, such as TBL (task-based learning), skimming, team work, brainstorm and others, which can offer students opportunities to fulfill tasks in which they can use language to achieve a specific outcome.IV. Teaching aids:Computer and blackboardV. Teaching important points:1) Make students have a clear mind for the structure of the text.2) Help students understand the theme of the text.VI. Teaching difficulties:1) So many new words may affect students’ understanding.2) How to get students to know about the functions of the skin and thecauses, characteristics and treatments for different degree burns,and the knowledge about giving first aid. VII. Blackboard design:

【課件展示】《秦朝中央集權(quán)制度的建立》《教材簡(jiǎn)析》《教學(xué)目標(biāo)》《教法簡(jiǎn)介》《教學(xué)過(guò)程設(shè)計(jì)及特色簡(jiǎn)述》【師】本節(jié)內(nèi)容以秦代政治體制和官僚系統(tǒng)的建立為核心內(nèi)容,主要包括秦朝中央集權(quán)制的建立的背景、建立過(guò)程及影響。本節(jié)內(nèi)容在整個(gè)單元中起到承前啟后的作用,在整個(gè)模塊中也有相當(dāng)重要的地位。讓學(xué)生了解中國(guó)古代中央集權(quán)政治體制的初建對(duì)于理解我國(guó)古代政治制度的發(fā)展乃至我們今天的政治體制是十分必要的。 本堂課我采用多媒體和講授法及歷史辯論法相結(jié)合,通過(guò)巧妙設(shè)計(jì)問(wèn)題情境,調(diào)動(dòng)學(xué)生的學(xué)習(xí)積極性,使學(xué)生主動(dòng)學(xué)習(xí),探究思考。教師引導(dǎo)和組織學(xué)生采取小組討論、情景體驗(yàn)等方式,達(dá)到教學(xué)目標(biāo)。 本節(jié)內(nèi)容分三個(gè)部分,下面首先看秦朝中央集權(quán)制度建立的前提即秦的統(tǒng)一

一、教材分析下面我來(lái)談一談對(duì)教材的認(rèn)識(shí):主要從教材的地位和作用、以及在此基礎(chǔ)上確立的教學(xué)目標(biāo)、教學(xué)重難點(diǎn)這三個(gè)方面來(lái)談。首先,來(lái)談教材的地位和作用:本課教材內(nèi)容主要從三個(gè)方面向?qū)W生介紹了現(xiàn)代中國(guó)教育的發(fā)展?fàn)顩r和趨勢(shì):人民教育的奠基、動(dòng)亂中的教育和教育的復(fù)興,全面講述了新中國(guó)教育的三個(gè)階段。本課是文化史中中國(guó)史部分的最后一課, 也是必修三冊(cè)書(shū)中唯一涉及教育的一課。而教育是思想文化史中的重要組成部分,江澤民同志在談到教育的時(shí)候曾經(jīng)說(shuō)過(guò),“百年大計(jì),教育為本。教育為本,在于育人”。教育是關(guān)系國(guó)計(jì)民生的大事。學(xué)生通過(guò)學(xué)習(xí)新中國(guó)教育發(fā)展的史實(shí),理解“科教興國(guó)”、“國(guó)運(yùn)興衰,系于教育”的深刻含義。最終由此激發(fā)學(xué)生樹(shù)立“知識(shí)改變命運(yùn)、讀書(shū)成就人生”的信念,樹(shù)立勤奮學(xué)習(xí)、成人成才、報(bào)效祖國(guó)、服務(wù)社會(huì)的崇高理想。故本課的教學(xué)有極大的現(xiàn)實(shí)意義。談完了教材的地位和作用,我再分析一下教學(xué)目標(biāo):

一、說(shuō)教材(一)、教材內(nèi)容《古代中國(guó)的發(fā)明和發(fā)現(xiàn)》是人教版高中歷史必修三第三單元第一課內(nèi)容,本課教材主要從五個(gè)方面的典型事例向?qū)W生介紹了古代中國(guó)幾千年的科技成就。本課一方面展示了古代中國(guó)人民的勤勞智慧以及對(duì)世界文明發(fā)展作出的巨大貢獻(xiàn),另一方面也提出了一個(gè)重大問(wèn)題引起學(xué)生的思考,即造成中國(guó)科技在近代落后的原因是什么。此外、本課在教材中具有承上啟下的地位和作用,前承中國(guó)傳統(tǒng)文化主流思想,后啟現(xiàn)代中國(guó)科學(xué)技術(shù)的發(fā)展。根據(jù)課標(biāo)要求和教材內(nèi)容,我將本課的三維目標(biāo)確定如下:(三)教學(xué)目標(biāo)(1)知識(shí)與能力:掌握中國(guó)古代科技進(jìn)步的基礎(chǔ)知識(shí),特別是四大發(fā)明。認(rèn)識(shí)古代中國(guó)四大發(fā)明對(duì)世界文明發(fā)展的貢獻(xiàn),以及取得重大成就的原因。⑵過(guò)程與方法:通過(guò)指導(dǎo)學(xué)生課前閱讀課本,在課堂上進(jìn)行問(wèn)題探究、實(shí)驗(yàn)體驗(yàn)以及歷史比較,學(xué)會(huì)總結(jié)歸納。

環(huán)節(jié)三:多媒體繼續(xù)展示石窟藝術(shù)、民族文學(xué)等,學(xué)生在感受少數(shù)民族文化成就的過(guò)程中不難得出結(jié)論:各民族文化都為中華文化作出了重要貢獻(xiàn),都是中華民族的驕傲。由此進(jìn)入第三目“中華之瑰寶,民族之驕傲”。各族人民對(duì)中華文化的認(rèn)同感和歸屬感,顯示了中華民族厚重的文化底蘊(yùn)和強(qiáng)大的民族凝聚力。環(huán)節(jié)四:合作探究中華文化博大精深的原因。學(xué)生調(diào)動(dòng)已有歷史知識(shí)儲(chǔ)備和課前搜集的材料分組交流:歷史上在思想文化方面,對(duì)諸家學(xué)說(shuō)所采取的兼收并蓄的學(xué)術(shù)主張;中國(guó)文化長(zhǎng)期吸收周邊少數(shù)民族的哪些優(yōu)秀文明;在對(duì)待外域文化上,中華民族是否敞開(kāi)博大胸懷揚(yáng)棄吸收。2、從現(xiàn)代找出能充分體現(xiàn)中華民族的文化開(kāi)放心態(tài)和中華文化非凡融合力的例子。這樣可增添幾分時(shí)代氣息,更好地服務(wù)于當(dāng)下實(shí)踐。

(4)自強(qiáng)不息 (引導(dǎo)學(xué)生簡(jiǎn)要了解介紹 “大禹治水”“ 愚公移山”“ 夸父追日”“ 富貴不能淫”等典故名言,注重從優(yōu)秀傳統(tǒng)文化和中華民族精神之間的關(guān)系角度總結(jié)。)三、永遠(yuǎn)高揚(yáng)的愛(ài)國(guó)主義旗幟這一目講述中華民族精神的核心,新時(shí)期愛(ài)國(guó)主義的主題?!咎骄咳浚?、團(tuán)結(jié)統(tǒng)一、愛(ài)好和平、勤勞勇敢、自強(qiáng)不息共同體現(xiàn)著一個(gè)什么主題?2、你知道哪些我國(guó)抒發(fā)愛(ài)國(guó)情懷的詩(shī)詞格言警句?哪些歷史故事或者你身邊的事例體現(xiàn)出了愛(ài)國(guó)主義的精神追求?你認(rèn)為新時(shí)期我國(guó)愛(ài)國(guó)主義主要體現(xiàn)在哪些方面?學(xué)生四人一個(gè)小組討論,選派代表發(fā)言【師生總結(jié)】:1、愛(ài)國(guó)主義是中華民族精神的核心,是中華民族的精神支柱。2、新時(shí)期愛(ài)國(guó)主義的主題:愛(ài)國(guó)主義是具體的,不同時(shí)期有不同的內(nèi)涵,新時(shí)期愛(ài)國(guó)與愛(ài)社會(huì)主義本質(zhì)上是一致的,發(fā)展中國(guó)特色社會(huì)主義,擁護(hù)祖國(guó)統(tǒng)一是新時(shí)期愛(ài)國(guó)主義的主題。

從質(zhì)量、體積、平均密度、公轉(zhuǎn)與自轉(zhuǎn)周期等各方面,地球沒(méi)有一項(xiàng)是最大值或最小值,這說(shuō)明地球僅僅是太陽(yáng)系中一顆最普通不過(guò)的一顆行星。2、地球又是一顆特殊的行星。問(wèn)題 :為什么?因?yàn)榈厍蚴悄壳拔覀円阎奈ㄒ淮嬖谏铮攸c(diǎn)是存在高級(jí)智慧生物的天體。問(wèn)題:為什么地球上會(huì)存在生命?原因:(1)地球所處的宇宙環(huán)境來(lái)說(shuō):地球處于一種相對(duì)安全的宇宙環(huán)境。例:A、九大行星公轉(zhuǎn)的同向性、同面 性、及公 轉(zhuǎn)軌道的近圓性。B 太陽(yáng)光照條件的穩(wěn)定性。從地球產(chǎn)生到地球上有生物,幾十億年期間,太陽(yáng) 沒(méi)有明顯的變化,地球所處的光照條件一直較穩(wěn)定,生命演化沒(méi)有中斷。(2)地球自身的物質(zhì)條件:例:A 日地距離適中,形成了適宜的溫度:日地距離適中,地球表面平均溫度15度,適合生物的生存。(擴(kuò)展:地球自轉(zhuǎn)速度適中,大氣層的保溫效應(yīng))B 地球質(zhì)量與體積適中,使地球有了適合的大氣條件。C 原始海洋的形成 :使 生命的出現(xiàn)成為可能。

2、建立國(guó)際新秩序(1)建立國(guó)際新秩序是解決和平與發(fā)展問(wèn)題的有效途徑為了和平與發(fā)展,必須改變舊的國(guó)際秩序,建立以和平共處五項(xiàng)原則為基礎(chǔ)的有利于世界和平與發(fā)展的國(guó)際新秩序。這是抑制霸權(quán)主義、強(qiáng)權(quán)政治,解決和平與發(fā)展問(wèn)題的有效途徑,是每個(gè)國(guó)家生存和發(fā)展的最基本和最重要的外部條件。教師活動(dòng):引導(dǎo)學(xué)生閱讀教材103頁(yè)“相關(guān)鏈接”材料,并思考所反映的問(wèn)題學(xué)生活動(dòng):積極思考并討論問(wèn)題教師點(diǎn)評(píng):世界發(fā)展的主體是世界各國(guó)人民。世界的管理必須由各國(guó)人民共同參與。這是各國(guó)人民的共同呼聲。(2)國(guó)際政治經(jīng)濟(jì)新秩序的主要內(nèi)容建立國(guó)際政治經(jīng)濟(jì)新秩序,就是要保障各國(guó)享有主權(quán)平等和內(nèi)政不受干涉的權(quán)利,保障各國(guó)享有平等參與國(guó)際事務(wù)的權(quán)利,保障各國(guó)特別是廣大發(fā)展中國(guó)家享有平等的發(fā)展權(quán)利,保障各個(gè)民族和各種文明共同發(fā)展的權(quán)利。
