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.
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:
今天我們來介紹一下必修五第四單元的授課方式。這個單元的題目是Making the news。應(yīng)該是學(xué)生比較感興趣的話題,學(xué)生往往對新聞工作充滿好奇,所以我們可以利用這個機會多設(shè)計一些師生互動和學(xué)生互動,來激發(fā)起學(xué)習(xí)的積極性,提高學(xué)習(xí)效率。同時我們可以利用這個單元不僅幫助學(xué)生掌握語言知識,培養(yǎng)語言能力,同時讓其了解新聞工作的重要性,培養(yǎng)起社會智能感。這個單元分為六個課時,它的教學(xué)目標是這樣的:語言目標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。 技能目標是能初步掌握約會的基本句型并在真實的場景下正確運用。新聞報道類文章的寫作技能。采訪的基本規(guī)范和溝通技能。情感目標是對新聞報道的客觀性和真實性有更好的理解。對新聞記者的職業(yè)有更深入的了解,并能體會其工作的重要性。下面我們來介紹一下第一課時的授課方式,第一課的教學(xué)目標是這樣的第一課時的教學(xué)目標語言目標:單詞:Occupation, journalist, editor, photographer, curious, personality, enthusiasm
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)By the end of the lesson, students will be able to:1. Language Skill Objective(語言技能目標): develop reading ability (skimming and scanning)as well as speaking ability.2. Cultural Knowledge Objective(文化知識目標): know about the cultural differences of using body language.3. Affective Objective(情感目標): increase students’ awareness of using body language correctly in different cultures. III.Teaching Focuses and Difficulties(教學(xué)重點和難點)1. Teaching Focuses(教學(xué)重點): the difference and similarity of body language in many parts of the world.2. Teaching Difficulties(教學(xué)難點): develop students’ reading abilities of skimming and scanning and ask the students to show their opinions with fluent English.
通過寫文章梗概,培養(yǎng)學(xué)生綜合運用語言的能力,學(xué)習(xí)用恰當?shù)挠⒄Z描述科學(xué)家的故事。這是本課的教學(xué)難點。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)計快速閱讀和精讀的問題,層層推進各種閱讀活動,讓學(xué)生對閱讀內(nèi)容從整體感知到細節(jié)理解,最后深層讀懂整篇文章,同時加強閱讀策略的指導(dǎo),讓每個學(xué)生都主動參與課堂教學(xué)活動,最終達到提高閱讀能力的目的。Step 4 Post-readingGroup Activities四人小組共同合作,在老師的適當指導(dǎo)下,就以下2個問題展開討論,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?
Good afternoon, everyone. It’s my great pleasure to be here sharing my lesson with you. The content of my lesson is Senior English for China Book5 Unit 3 Life in the Future.

明確:(1)結(jié)繩記事說。原始記事的一種方法。人類在沒有發(fā)明文字或文字使用尚不普遍時,常用在繩索或類似物件上打結(jié)的方法記錄數(shù)字,表達某種意思,用以傳達信息,處理事件。 (2)書畫說。(3)倉頡造字說。中國自古就有倉頡造字之說。文字的發(fā)明是人類發(fā)展史上一件石破天驚的大事,它將人們的思維、語言、經(jīng)驗以及復(fù)雜的社會現(xiàn)象記錄下來,使文化得以傳播交流、世代傳承。2、漢字的形體:中華民族五千年的歷史中,漢字的演變,從甲骨文--金文--大篆--小篆--隸書--草書--楷書--行書,字形由象形到點橫豎撇捺的方塊字,經(jīng)歷了漫長的歲月。其中凝聚著民族的智慧,也體現(xiàn)出漢字逐步完善的過程,凸顯其方方正正、四平八穩(wěn)的特點。漢字又是一種文化的體現(xiàn),那些經(jīng)過藝術(shù)處理的漢字或跳起了拉丁舞、有的如同酒醉的成龍打起了醉拳,更是讓我們感到的是在欣賞漢字在紙張上跳舞,所以:書法是“紙上的舞蹈”。請大家看到書上的相關(guān)內(nèi)容,注意每一種形體的漢字的載體是什么,其功能又有什么不一樣。
探究、討論、交流:1、包弟討人喜歡,作者卻不得不將它送走,為什么?2、送走包弟后,作者為什么先是感覺輕松,隨后覺得沉重?3、“您的小狗怎樣?”這句話反復(fù)出現(xiàn),有什么用意?4、“整整十三年零五個月過去了”“整整”一詞有什么作用?5、“滿園的創(chuàng)傷使我的心仿佛又給放在油鍋里熬煎”這句話如何理解?6、“我懷念包弟,我想向它表示歉意?!比绾卫斫??學(xué)生各抒己見后教師結(jié)合材料發(fā)表看法明確總結(jié)特別是最后一個問題得出作者這發(fā)之心底的語言,不僅僅是歉意,更是發(fā)自靈魂深處的懺悔!是對生命的尊重,是一個有良知的作家對反省歷史的呼號。第三環(huán)節(jié)“認識你自己”——懺悔意識與我引導(dǎo)學(xué)生正視和反省成長過程中曾犯下過錯。并布置課后作業(yè):要求學(xué)生課后在本周隨筆中談反省懺悔后的感受。
三、文本中的句子解決完畢,大家對文本內(nèi)容的理解更加深入了。請速度文本,思考:《論語》具體涉及了哪些方面的內(nèi)容,體現(xiàn)了孔子什么觀點?明確:主要有治學(xué)、從政、修身養(yǎng)性和交友治道等方面,體現(xiàn)了孔子“克己復(fù)禮”的思想。四、 教師引導(dǎo)學(xué)生討論: 如何評價孔子的言行和觀點?從古至今人們對孔子有哪些評價?明確:1、春秋戰(zhàn)國時代, 孔子門人及其后學(xué)者均推尊孔子。門人中以子貢為代表,他對孔子贊美備至,奉如天人,把孔子比擬為高天、日月、木鐸,凡人是永遠不可企及的,認為孔子是天生的圣人,“仰之彌高,鉆之彌堅”。亞圣孟子認為孔子所行的“圣人之道”是遍及自然界和社會的至高準則。然而當時民間一般看法認為孔子是博學(xué)成名的大學(xué)者。
(二)?過程與方法? 4.?觀察生活中的慣性現(xiàn)象,了解力和運動的關(guān)系? 5.?通過實驗加深對牛頓第一定律的理解? 6.?理解理想實驗是科學(xué)研究的重要方法? (三)?情感態(tài)度與價值觀? 7.?通過伽利略和亞里士多德對力和運動關(guān)系的不同認識,了解人類認識事物本質(zhì)的曲折性? 8.?感悟科學(xué)是人類進步的不竭動力
導(dǎo)語在必修第一冊中,我們研究了函數(shù)的單調(diào)性,并利用函數(shù)單調(diào)性等知識,定性的研究了一次函數(shù)、指數(shù)函數(shù)、對數(shù)函數(shù)增長速度的差異,知道“對數(shù)增長” 是越來越慢的,“指數(shù)爆炸” 比“直線上升” 快得多,進一步的能否精確定量的刻畫變化速度的快慢呢,下面我們就來研究這個問題。新知探究問題1 高臺跳水運動員的速度高臺跳水運動中,運動員在運動過程中的重心相對于水面的高度h(單位:m)與起跳后的時間t(單位:s)存在函數(shù)關(guān)系h(t)=-4.9t2+4.8t+11.如何描述用運動員從起跳到入水的過程中運動的快慢程度呢?直覺告訴我們,運動員從起跳到入水的過程中,在上升階段運動的越來越慢,在下降階段運動的越來越快,我們可以把整個運動時間段分成許多小段,用運動員在每段時間內(nèi)的平均速度v ?近似的描述它的運動狀態(tài)。
二、典例解析例4. 用 10 000元購買某個理財產(chǎn)品一年.(1)若以月利率0.400%的復(fù)利計息,12個月能獲得多少利息(精確到1元)?(2)若以季度復(fù)利計息,存4個季度,則當每季度利率為多少時,按季結(jié)算的利息不少于按月結(jié)算的利息(精確到10^(-5))?分析:復(fù)利是指把前一期的利息與本金之和算作本金,再計算下一期的利息.所以若原始本金為a元,每期的利率為r ,則從第一期開始,各期的本利和a , a(1+r),a(1+r)^2…構(gòu)成等比數(shù)列.解:(1)設(shè)這筆錢存 n 個月以后的本利和組成一個數(shù)列{a_n },則{a_n }是等比數(shù)列,首項a_1=10^4 (1+0.400%),公比 q=1+0.400%,所以a_12=a_1 q^11 〖=10〗^4 (1+0.400%)^12≈10 490.7.所以,12個月后的利息為10 490.7-10^4≈491(元).解:(2)設(shè)季度利率為 r ,這筆錢存 n 個季度以后的本利和組成一個數(shù)列{b_n },則{b_n }也是一個等比數(shù)列,首項 b_1=10^4 (1+r),公比為1+r,于是 b_4=10^4 (1+r)^4.
二、典例解析例3.某公司購置了一臺價值為220萬元的設(shè)備,隨著設(shè)備在使用過程中老化,其價值會逐年減少.經(jīng)驗表明,每經(jīng)過一年其價值會減少d(d為正常數(shù))萬元.已知這臺設(shè)備的使用年限為10年,超過10年 ,它的價值將低于購進價值的5%,設(shè)備將報廢.請確定d的范圍.分析:該設(shè)備使用n年后的價值構(gòu)成數(shù)列{an},由題意可知,an=an-1-d (n≥2). 即:an-an-1=-d.所以{an}為公差為-d的等差數(shù)列.10年之內(nèi)(含10年),該設(shè)備的價值不小于(220×5%=)11萬元;10年后,該設(shè)備的價值需小于11萬元.利用{an}的通項公式列不等式求解.解:設(shè)使用n年后,這臺設(shè)備的價值為an萬元,則可得數(shù)列{an}.由已知條件,得an=an-1-d(n≥2).所以數(shù)列{an}是一個公差為-d的等差數(shù)列.因為a1=220-d,所以an=220-d+(n-1)(-d)=220-nd. 由題意,得a10≥11,a11<11. 即:{█("220-10d≥11" @"220-11d<11" )┤解得19<d≤20.9所以,d的求值范圍為19<d≤20.9
二、典例解析例10. 如圖,正方形ABCD 的邊長為5cm ,取正方形ABCD 各邊的中點E,F,G,H, 作第2個正方形 EFGH,然后再取正方形EFGH各邊的中點I,J,K,L,作第3個正方形IJKL ,依此方法一直繼續(xù)下去. (1) 求從正方形ABCD 開始,連續(xù)10個正方形的面積之和;(2) 如果這個作圖過程可以一直繼續(xù)下去,那么所有這些正方形的面積之和將趨近于多少?分析:可以利用數(shù)列表示各正方形的面積,根據(jù)條件可知,這是一個等比數(shù)列。解:設(shè)正方形的面積為a_1,后續(xù)各正方形的面積依次為a_2, a_(3, ) 〖…,a〗_n,…,則a_1=25,由于第k+1個正方形的頂點分別是第k個正方形各邊的中點,所以a_(k+1)=〖1/2 a〗_k,因此{a_n},是以25為首項,1/2為公比的等比數(shù)列.設(shè){a_n}的前項和為S_n(1)S_10=(25×[1-(1/2)^10 ] )/("1 " -1/2)=50×[1-(1/2)^10 ]=25575/512所以,前10個正方形的面積之和為25575/512cm^2.(2)當無限增大時,無限趨近于所有正方形的面積和
課前小測1.思考辨析(1)若Sn為等差數(shù)列{an}的前n項和,則數(shù)列Snn也是等差數(shù)列.( )(2)若a1>0,d<0,則等差數(shù)列中所有正項之和最大.( )(3)在等差數(shù)列中,Sn是其前n項和,則有S2n-1=(2n-1)an.( )[答案] (1)√ (2)√ (3)√2.在項數(shù)為2n+1的等差數(shù)列中,所有奇數(shù)項的和為165,所有偶數(shù)項的和為150,則n等于( )A.9 B.10 C.11 D.12B [∵S奇S偶=n+1n,∴165150=n+1n.∴n=10.故選B項.]3.等差數(shù)列{an}中,S2=4,S4=9,則S6=________.15 [由S2,S4-S2,S6-S4成等差數(shù)列得2(S4-S2)=S2+(S6-S4)解得S6=15.]4.已知數(shù)列{an}的通項公式是an=2n-48,則Sn取得最小值時,n為________.23或24 [由an≤0即2n-48≤0得n≤24.∴所有負項的和最小,即n=23或24.]二、典例解析例8.某校新建一個報告廳,要求容納800個座位,報告廳共有20排座位,從第2排起后一排都比前一排多兩個座位. 問第1排應(yīng)安排多少個座位?分析:將第1排到第20排的座位數(shù)依次排成一列,構(gòu)成數(shù)列{an} ,設(shè)數(shù)列{an} 的前n項和為S_n。
