When it comes to the students’ studying methods, I'd like to introduce my Ss first. The Ss have a good command of basic language points. They’re interested in learning English, and they take an active part in English class, so they will have fun in autonomous, cooperative and inquiry learning. I will just serve as a guide, showing them the way to explore how to make more progress in their English learning.Now it’s time for the most important stage of this lesson. My teaching procedures are arranged as follows:Step1.Leading-in (3 minute)Play a video of a wide variety of wildlife to introduce my topic. Step2. Speaking (12 minutes)We will use our textbook Page25. Let the Ss fast read the short paragraph to warm up. Ask them to talk about the report on some endangered wildlife in China with the dialogue patterns on the screen. Lastly, I will invite some groups to demonstrate their dialogues about saving wildlife in China.Step3.English play (3 minutes)Watch another video in praise of their excellent performance just now.

Music appreciation (3 minutes)Let the Ss appreciate the song Earth Song by Michael Jackson. Last but not the least, I will show you my blackboard design.
五.研習(xí)第一段:1.誦讀指導(dǎo)要處理好句中停頓2.請學(xué)生對照注釋翻譯本段重點(diǎn)詞句:學(xué)不可以已已:停止。青,取之于藍(lán)而青于藍(lán)于:從;比。木直中繩中:zhàng符合,合于。雖有槁暴,不復(fù)挺者,揉使之然也有通又,揉通煣,以火烘木,使其彎曲。然:這樣。翻譯:故木受繩則直,金就礪則利,君子博學(xué)而日參省乎己,則知明而行無過矣。所以木材經(jīng)墨線畫過(再用斧鋸加工)就直了,金屬刀劍拿到磨刀石上(磨過)就鋒利了,君子廣博地學(xué)習(xí)并且每天對自己檢驗(yàn)反省,就能智慧明達(dá),行為沒有過錯(cuò)了。3.本段是從哪個(gè)角度論述中心論點(diǎn)的?明確:本段是從學(xué)習(xí)的意義這個(gè)角度論述中心論點(diǎn)的。荀子認(rèn)為人的知識(shí)、道德、才能都不是天生成的,而是后天不斷學(xué)習(xí)獲得的,學(xué)習(xí)的意義十分重大,所以學(xué)習(xí)不能停止。4.本段中幾個(gè)比喻句是為了說明什么道理?學(xué)生討論發(fā)言,教師明確:
Step 2 Listening and Talking1. The teacher is advised to talk with their new students about the related topic: Boys and girls, do you know some structures to talk about future activities? Talking about future activitiesWe’ll …I plan to …There’ll be …I hope to …We’re going to …2. After their small talk, the teacher can move on by playing the listening and solve the following task.Underline the expressions in the sentences below Cao Jing and Max use to talk about the future.We’ll learn useful skills.I plan to improve my spoken English.There’ll be students from different schools.I hope to make new friends.We’ll talk about teenage life.I’ll learn to make a fire.There’ll be students from different countries at the camp.There’ll be some experts there to show us how to live in the wild.We’re going to learn about wildlife.I’m going to give a speech.I think I’m going to enjoy the activities.I think we’ll have a lot of fun.3. Work in groups. Plan a youth camp.Teacher make the Ss think of ideas for the camp. And they can use the questions below to get started. And have the Ss present their ideas for a youth camp to the class.●What kind of camp is it?●Who will be there?●What will they do?●What will they learn?
活動(dòng)內(nèi)容:教師首先讓學(xué)生回顧學(xué)過的三類事件,接著讓學(xué)生拋擲一枚均勻的硬幣,硬幣落下后,會(huì)出現(xiàn)正面朝上、正面朝下兩種情況,你認(rèn)為正面朝上和正面朝下的可能性相同嗎?(讓學(xué)生體驗(yàn)數(shù)學(xué)來源于生活)?;顒?dòng)目的:使學(xué)生回顧學(xué)過的三類事件,并由擲硬幣游戲培養(yǎng)學(xué)生猜測游戲結(jié)果的能力,并從中初步體會(huì)猜測事件可能性。讓學(xué)生體會(huì)猜測結(jié)果,這是很重要的一步,我們所學(xué)到的很多知識(shí),都是先猜測,再經(jīng)過多次的試驗(yàn)得出來的。而且由此引出猜測是需通過大量的實(shí)驗(yàn)來驗(yàn)證。這就是我們本節(jié)課要來研究的問題(自然引出課題)。
這是本節(jié)課的重點(diǎn)。讓同學(xué)們將∠aob對折,再折出一個(gè)直角三角形(使第一條折痕為斜邊),然后展開,請同學(xué)們觀察并思考:后折疊的二條折痕的交點(diǎn)在什么地方?這兩條折痕與角的兩邊有什么位置關(guān)系?這兩條折痕在數(shù)量上有什么關(guān)系?這時(shí)有的同學(xué)會(huì)說:“角的平分線上的點(diǎn)到角的兩邊的距離相等”.即得到了角平分線的性質(zhì)定理的猜想。接著我會(huì)讓同學(xué)們理論證明,并轉(zhuǎn)化為符號語言,注意分清題設(shè)和結(jié)論。有的同學(xué)會(huì)用全等三角形的判定定理aas證明,從而證明了猜想得到了角平分線的性質(zhì)定理。
問題1:你能證明“兩條直線被第三條直線所截,如果內(nèi)錯(cuò)角相等,那么這兩條直線平行”這個(gè)命題的正確性嗎?已知:如圖,∠1和∠2是直線a,b被直線c截出的內(nèi)錯(cuò)角,且∠1=∠2.求證:a∥b. 問題2:你能證明“兩條直線被第三條直線所截,如果同旁內(nèi)角互補(bǔ),那么這兩條直線平行”這個(gè)命題的正確性嗎?已知:如圖,∠1和∠2是直線a、b被直線c截出的同旁內(nèi)角,且∠1與∠2互補(bǔ).求證:a∥b
1、交流與發(fā)現(xiàn)為了了解本校學(xué)生暑假期間參加體育活動(dòng)的情況,學(xué)校準(zhǔn)備抽取一部分學(xué)生進(jìn)行調(diào)查,你認(rèn)為按下面的調(diào)查方法取得的結(jié)果能反映全校學(xué)生的一般情況嗎?如果不能反映,應(yīng)當(dāng)如何改進(jìn)調(diào)查方法?方法1:調(diào)查學(xué)校田徑隊(duì)的30名同學(xué);方法2:調(diào)查每個(gè)班的男同學(xué);方法3:從每班抽取1名同學(xué)進(jìn)行調(diào)查;方法4:選取每個(gè)班級中的一半學(xué)生進(jìn)行調(diào)查.通過前面的活動(dòng),學(xué)生親身經(jīng)歷了一次數(shù)據(jù)的調(diào)查過程,并通過對所得數(shù)據(jù)的計(jì)算和分析,了解了自己在家干家務(wù)活的時(shí)間所處的位置和水平,在調(diào)查過程中體會(huì)到調(diào)查方便有效的重要性.接下來,就能很好地解決交流與發(fā)現(xiàn)中的問題.師生共同討論完成交流與發(fā)現(xiàn).
學(xué)習(xí)過程:一、自主預(yù)習(xí)課本P175——186的內(nèi)容,獨(dú)立完成課后練習(xí)1、2、3、4、5后,與小組同學(xué)交流(課前完成)二、回顧課本,思考下列問題:1.SAS定理的內(nèi)容2.ASA定理的內(nèi)容3.SSS定理的內(nèi)容4.幾何證明的過程的步驟
活動(dòng)內(nèi)容:① 已知,如圖,在三角形ABC中,AD平分外角∠EAC,∠B=∠C.求證:AD∥BC分析:要證明AD∥BC,只需證明“同位角相等”,即需證明∠DAE=∠B.證明:∵∠EAC=∠B+∠C(三角形的一個(gè)外角等于和它不相鄰的兩個(gè)內(nèi)角的和)∠B=∠C(已知)∴∠B=∠EAC(等式的性質(zhì))∵AD平分∠EAC(已知)∴∠DAE=∠EAC(角平分線的定義)∴∠DAE=∠B(等量代換)∴AD∥BC(同位角相等,兩直線平行)想一想,還有沒有其他的證明方法呢?這個(gè)題還可以用“內(nèi)錯(cuò)角相等,兩直線平行”來證.
創(chuàng)設(shè)情境,導(dǎo)入新課:你對母親知多少師問1:我們5月份剛過了一個(gè)重要的節(jié)日,你知道是什么嗎?----母親節(jié)。師問2:那你知道媽媽的生日嗎?(舉手示意),每個(gè)媽媽都知道自己孩子的生日,請不知道的同學(xué)回家了解一下,多關(guān)心一下自己的父母。師問3:那你知道媽媽最愛吃的菜嗎?你可以選擇知道、不知道或者是沒有愛吃的(拖動(dòng)白板上相對應(yīng)的表情符號)。請大家用不同的手勢表示出來。我找3名同學(xué)統(tǒng)計(jì)各組的數(shù)據(jù),寫在黑板上(隨機(jī)找3名學(xué)生數(shù)人數(shù))。下面我來隨機(jī)采訪一下:你媽媽最喜歡吃的菜是什么?(教師隨機(jī)采訪,結(jié)合營養(yǎng)搭配和感恩教育)
從課程內(nèi)容來看,本節(jié)課屬于“圖形與幾何”中“圖形的性質(zhì)”部分。依據(jù)課標(biāo)的要求,我從以下四個(gè)方面設(shè)定了課程目標(biāo),分別是:1。知識(shí)技能:(1)掌握判定直角三角形全等的“斜邊、直角邊”定理。(2)已知一直角邊和斜邊,能用尺規(guī)作出直角三角形。2。數(shù)學(xué)思考:(1)經(jīng)歷探索、猜想、證明的過程,進(jìn)一步體會(huì)證明的必要性,發(fā)展推理能力和有條理的表達(dá)能力。(2)在探究過程中,滲透由特殊到一般的數(shù)學(xué)思想方法。3。問題解決:能利用直角三角形的全等解決有關(guān)問題。4。情感態(tài)度:通過學(xué)習(xí),讓學(xué)生感受數(shù)學(xué)證明的嚴(yán)謹(jǐn)性,發(fā)展勇于質(zhì)疑、嚴(yán)謹(jǐn)求實(shí)的科學(xué)態(tài)度。
(4)Finally, I will ask the SS what this sentence mean:It is always calm before a storm.Purpose: attract the SS attention and bring them into discussionStep 2: Pre-reading 讀前Here, I will do the second question in pre-reading first.
