Pour the tea.(邊倒茶,邊說兩遍)。
① 教師詢問學(xué)生“What day is today?”,學(xué)生說出“Today is …”。而后又問學(xué)生:“What’s the date?”,幫助學(xué)生說出今天的具體日期:“It’s …”。 ② 讓學(xué)生拿出課前準備的年歷(最好是學(xué)生自己制作的),教師隨意指著某天詢問學(xué)生:“What’s the date?”,而后請學(xué)生拿著年歷相互用“What’s the date? It’s ….”進行問答練習。③ 教師拿著年歷從一月開始問學(xué)生:“Who has a birthday in January? Please stand up.”,而后教師問起立的學(xué)生:“What’s the date?”,讓一月份生日的學(xué)生答出具體日期。④ 請若干名學(xué)生代替老師進行提問,從二月到十二月?;顒铀模篖et’s talk教學(xué)參考時間:8分鐘① 教師播放對話錄音兩遍,而后提問:“When is Sarah’s birthday?

例7 用描述法表示拋物線y=x2+1上的點構(gòu)成的集合.【答案】見解析 【解析】 拋物線y=x2+1上的點構(gòu)成的集合可表示為:{(x,y)|y=x2+1}.變式1.[變條件,變設(shè)問]本題中點的集合若改為“{x|y=x2+1}”,則集合中的元素是什么?【答案】見解析 【解析】集合{x|y=x2+1}的代表元素是x,且x∈R,所以{x|y=x2+1}中的元素是全體實數(shù).變式2.[變條件,變設(shè)問]本題中點的集合若改為“{y|y=x2+1}”,則集合中的元素是什么?【答案】見解析 【解析】集合{ y| y=x2+1}的代表元素是y,滿足條件y=x2+1的y的取值范圍是y≥1,所以{ y| y=x2+1}={ y| y≥1},所以集合中的元素是大于等于1的全體實數(shù).解題技巧(認識集合含義的2個步驟)一看代表元素,是數(shù)集還是點集,二看元素滿足什么條件即有什么公共特性。

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。
(2)、市場調(diào)節(jié)存在固有的弊端:自發(fā)性:由于市場調(diào)節(jié)是在價值規(guī)律自發(fā)作用下進行的,在利益驅(qū)動下會產(chǎn)生一些違反市場原則的行為,如制造、銷售假冒偽劣商品,大量排放廢水、廢氣破壞環(huán)境,竊取他人智力成果等等。盲目性:由于人們不可能完全掌握生產(chǎn)各方面信息及其變化趨勢,致使決策帶有一定的盲目性。如某種商品有利可圖則一哄而上,反之則一哄而退,從而造成資源浪費和消費得不到充分滿足。滯后性:由于市場價格的形成和傳遞有一個過程,一旦傳遞到生產(chǎn)經(jīng)營者手中進行生產(chǎn)調(diào)整,就有一個時間差,致使市場調(diào)節(jié)帶有滯后性,成為一種事后調(diào)節(jié)。教師活動:請同學(xué)們想一想,市場的這些弊端和不足,會導(dǎo)致什么后果?(3)、危害教師總結(jié):資源浪費,經(jīng)濟波動與混亂,分配不公兩極分化等。設(shè)計意圖:通過創(chuàng)設(shè)情景,加深對市場調(diào)節(jié)局限性的理解;要求學(xué)生結(jié)合生活實例探討其弊端有助于加強對其產(chǎn)生原因和表現(xiàn)的記憶和理解。
一、對教材內(nèi)容的處理根據(jù)新課程標準的要求、知識的跨度、學(xué)生的認知水平,我對教材內(nèi)容有增有減。二、教學(xué)策略的選用(一)運用了模擬活動,強化學(xué)生的生活體驗,本框題知識所對應(yīng)的經(jīng)濟現(xiàn)象,學(xué)生已具有了一定的生活體驗,但是缺乏對這種體驗的深入思考。因此在進一步強化這種體驗的過程中進行了思考和認知,使知識從學(xué)生的生活體驗中來,從學(xué)生的思考探究中來,有助于提高學(xué)生的興趣,有助于充分調(diào)動學(xué)生現(xiàn)有的知識,培養(yǎng)學(xué)生的各種能力,也有助于實現(xiàn)理論知識與實際生活的交融。(二)組織學(xué)生探究知識并形成新的知識我從學(xué)生的生活體驗入手,運用案例等形式創(chuàng)設(shè)情境呈現(xiàn)問題,使學(xué)生在自主探索、合作交流的過程中,發(fā)現(xiàn)問題、分析問題、解決問題,在問題的分析與解決中主動構(gòu)建知識。也正是由于這些認識來自于學(xué)生自身的體驗,因此學(xué)生不僅“懂”了,而且“信”了。從內(nèi)心上認同這些觀點,進而能夠主動地內(nèi)化為自己的情感、態(tài)度、價值觀,并融入到實踐活動中去,有助于實現(xiàn)知、行、信的統(tǒng)一。
