本文篇幅較長,并且有一字句不易理解,因而對高一學(xué)生來說完全讀懂內(nèi)容有一些困難。這樣的話,老師就要做好引導(dǎo)工作,把一些難點,或是出現(xiàn)詞類活用比較多,局勢比較特殊的句子,老師可以先給學(xué)生畫出來,存疑,或是與同學(xué)們一起討論解決。對那些不易懂的字詞就引導(dǎo)學(xué)生聯(lián)系上下文提供的語境、前后涉及的情節(jié)加以推測、判斷,以培養(yǎng)學(xué)生依據(jù)文脈推斷詞義的好方法。要求學(xué)生點出重點實詞、框出通假字,主要是為幫助學(xué)生積累和掌握一些文言文中常見的一詞多義、異讀現(xiàn)象、古今異義和通假現(xiàn)象的詞語,并進一步得出規(guī)律,指導(dǎo)今后的文言文學(xué)習(xí)。詞類活用和特殊句式在文言文翻譯中難度較大,也是本文教學(xué)的兩大難點。要求學(xué)生標(biāo)出有活用現(xiàn)象的字和劃出句式特殊的句子,是基于兩點考慮:1、積累一定數(shù)量的第一手例句;2、引導(dǎo)學(xué)生加以分類,找出每類的相同特征,并抽取出來形成規(guī)律性的東西,從而上升到理性認(rèn)識,使學(xué)生能由學(xué)會一個到會學(xué)多個。翻譯過程中注重指導(dǎo)學(xué)生養(yǎng)成用符號法表示重點字句的好習(xí)慣,如點、框、圈、劃線等符號應(yīng)約定一致,便于突出翻譯中的重點、難點及復(fù)習(xí)。我的提示著重歸納了實詞“制”“亡”“遺”“利”等,名詞活用、形容詞活用、使動用法,被動句、狀語后置句。

《勸學(xué)》是普通高中課程標(biāo)準(zhǔn)試驗教科書語文必修三第三單元的重點篇目,該文集中反映著名思想家荀子在學(xué)習(xí)問題上的觀點和精彩斐然的論證藝術(shù)。該單元所選課文都是古代的議論性散文。通過本單元的學(xué)習(xí)在于讓學(xué)生感受我國傳統(tǒng)文化的精神,掌握基礎(chǔ)的文言語法知識,學(xué)習(xí)如何清晰有力的表達自己的思想和見解。本文安排在單元的第一篇,如何指導(dǎo)學(xué)生學(xué)好這篇課文,是實現(xiàn)“授之以漁”,樹立學(xué)生學(xué)好文言文的信心,掌握文言學(xué)習(xí)方法的關(guān)鍵。根據(jù)新課標(biāo)倡導(dǎo)從“知識與能力”、“過程與方法”、“情感態(tài)度與價值觀”三方面出發(fā)設(shè)計課程目標(biāo)的要求和高一的學(xué)生對于文言文的知識還在積累的階段,應(yīng)該注重基礎(chǔ)知識的積累和一定量的誦讀的實際情況。我擬確定以下教學(xué)目標(biāo):1,了解荀子論述學(xué)習(xí)的思想,明確學(xué)習(xí)要靠積累、堅持不懈、專心致志的道理。2,掌握積累文言實詞、虛詞,活用、古今異議等現(xiàn)象和固定句式。

一、對教材內(nèi)容的處理根據(jù)新課程標(biāo)準(zhǔn)的要求、知識的跨度、學(xué)生的認(rèn)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(rèn)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(rèn)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(rèn)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。

2、傳授新知與學(xué)生展示(35分鐘) 先由老師點出本課的知識點,它包括:(1)經(jīng)濟全球化深入發(fā)展:結(jié)合課本91-93頁理解經(jīng)濟全球化的含義;經(jīng)濟全球化的表現(xiàn):生產(chǎn)全球化,貿(mào)易全球化,資本全球化;跨國公司是實現(xiàn)經(jīng)濟全球化的載體。(跨國公司的含義、目的、作用分別是什么)(2)經(jīng)濟全球化的影響: 經(jīng)濟全球化的實質(zhì):以發(fā)達資本主義國家為主導(dǎo)的經(jīng)濟全球化;消極影響積極影響;如何應(yīng)對經(jīng)濟全球化。講完了知識點,接著回歸圖片和書本的材料,給學(xué)生留下三個問題進行小組討論:A :談?wù)勀愀惺艿降慕?jīng)濟全球化B :怎樣理解經(jīng)濟全球化是一把“雙刃劍”C:假如你是一位企業(yè)經(jīng)營者,面對經(jīng)濟全球化趨勢,你會怎么做?先完成討論的小組可舉手示意老師給予檢查,老師根據(jù)需要抽查同學(xué)到講臺進行展示討論的結(jié)果,并對表現(xiàn)突出的小組進行當(dāng)堂獎勵。

(2)世界觀,人生觀,價值觀是人們文化素養(yǎng)的核心和標(biāo)志。一旦形成就會對人產(chǎn)生深遠(yuǎn)持久的影響。(但隨著生活閱歷的變化,人們文化素養(yǎng)的提高,人們的“三觀”會發(fā)生變化。)總之“潛移默化”指每時每刻,不知不覺;是從文化對人影響的過程來看的。“深遠(yuǎn)持久”指經(jīng)年累月,難以抹去;是從文化對人影響的結(jié)果上說的。3.課堂總結(jié):首先啟動學(xué)生思維,教會學(xué)生把握知識主線,建構(gòu)知識體系,先由學(xué)生進行總結(jié),然后教師進行必要的補充4、布置作業(yè):布置作業(yè)。運用文化對人的影響的知識分析“近朱者赤,近墨者黑”,并且應(yīng)該如何處理朋友之間的關(guān)系。設(shè)計這個作業(yè)的意圖是既讓學(xué)生靈活運用所學(xué)知識,同時又讓學(xué)生回歸生活,如何處理朋友之間的關(guān)系。5、板書設(shè)計遵循板書設(shè)計的實用性、直觀性的原則,根據(jù)本課的教材特點,我采用結(jié)構(gòu)式板書,這樣設(shè)計比較直觀、系統(tǒng),以便于學(xué)生能夠系統(tǒng)把握和理解知識。

(二)引入內(nèi)容1、播放幻燈片,從名言引出思考,什么是文化,如何理解文化?學(xué)生探究,既可質(zhì)疑,也可談自己對文化的理解2、幻燈片,以三組幻燈,分三個階段,學(xué)生分別通過小組討論的形式,歸納總結(jié)文化現(xiàn)象的三個特征3、根據(jù)對文化現(xiàn)象的認(rèn)識,歸納總結(jié)文化的內(nèi)涵及外延小活動:把不是文化的山、水、樹,由幾組同學(xué)畫出來,體會文化的含義4、一組判斷題,哪些是文化的,哪些不是5、理解文化的特點首先,根據(jù)前面,總結(jié)文化現(xiàn)象的特征,歸納出文化的普通性及特殊性其次,播放視頻,歸納總結(jié)文化是人類特有的現(xiàn)象第三,根據(jù)教材材料,小組探究總結(jié),文化是后天習(xí)得的第四,借助小活動的材料,歸納,文化需要一定的物質(zhì)載體6、文化的作用首先、觀看視頻,小組探究總結(jié),文化對于人的影響其次,觀看視頻,小組探究總結(jié),文化對社會的影響

3、文化的力量。為了使學(xué)生能辨證地分析文化的力量,我設(shè)計了兩個問題進行探討:(1)是不是任何文化都能起促進作用?(2)你在聽或唱國歌時感受到一種什么樣的力量?這樣,學(xué)生在對比中學(xué)會辨證地分析文化的力量——先進的、健康的文化能促進社會發(fā)展和個人成長;落后的、腐朽的文化則阻礙社會發(fā)展和個人成長。同時還能提高學(xué)生的文化賞析能力,從而引導(dǎo)學(xué)生裝自覺參加健康有益的文化活動,抵制不良文化的影響,投身到社會主義精神文明建設(shè)中去。關(guān)于課堂練習(xí),我準(zhǔn)備了5個針對性比較強的選擇題,從而加深鞏固本框題的重難點知識。最后,播放歌曲《走進新時代》,展示本課知識結(jié)構(gòu),指出本框題需重點掌握的問題,結(jié)束本課教學(xué)。課后作業(yè),我設(shè)計了這樣一個辨析的題目:文化是人們創(chuàng)造的全部財富的總和,它是人類特有的現(xiàn)象。

2. let the Ss complete the forms paragraph by paragraph. Purpose here is to help Ss to get the habit of reading a passage as a whole, and pay attention to the organization of the text, as a result the Ss will fully understand the whole passage.3. ask Ss to retell the passage with the help of the key words in the form.Since the Ss in the class are in different levels, so I let them to fill in the blank to understand the meaning of the words and phrases better.

課前活動:分成四組,對南京三個住房地段進行調(diào)查,新街口夫子廟、板倉、仙林,對住房居民進行問卷調(diào)查,自行設(shè)計調(diào)查問卷,分析該地段的房價要求,居民的要求,居民為何要在該地段購買住房,基礎(chǔ)設(shè)施設(shè)置等等其它與居民購房有關(guān)的因素?!粼O(shè)計意圖:利用課前小組探究形式對所學(xué)問題進行相關(guān)調(diào)查,不僅讓學(xué)生掌握知識了解知識來源于社會還能培養(yǎng)學(xué)生深入生活交際表達能力以及合作探究能力;3.問題設(shè)計同學(xué)們,不知道你們在調(diào)查過程中是否發(fā)現(xiàn)一個問題,郊區(qū)的房子,特別是別墅,都是些高檔居所,許多有錢人的居住場所,那為什么會這樣呢?伴隨著城市化進程中居民都往城里擠,為什么還會有許多有錢人往郊區(qū)搬呢?這就是我們今天要研究的第二個問題:逆城市化?!粼O(shè)計意圖:承轉(zhuǎn)過渡知識,從購房選擇因素的學(xué)習(xí)過渡到郊區(qū)化的學(xué)習(xí),同時培養(yǎng)學(xué)生發(fā)現(xiàn)問題的能力,給學(xué)生以啟迪。

教學(xué)過程:(一)導(dǎo)入:課前放《愛的奉獻》歌曲,同時不斷播放一些有關(guān)“愛”的主題的圖片,渲染一種情感氛圍。師說:同學(xué)們,誰能說說這組圖片的主題應(yīng)該是什么?生(七嘴八舌):母愛,不對是親情……是友情、還有人與人互相幫助……那組軍人圖片是說保衛(wèi)國家,應(yīng)該是愛國……那徐本禹和感動中國呢?…………生答:是關(guān)于愛的方面師說:不錯,是關(guān)于愛的方面。那么同學(xué)們,今天就以“愛的奉獻”為話題,來寫一篇議論文如何?生答:老師,還是寫記敘文吧。生答:就是,要不議論文寫出來也象記敘文。師問:為什么?生答:老師,這個話題太有話說了,一舉例子就收不住了,怎么看怎么象記敘文。生答:就是,再用一點形容詞,就更象了。眾人樂。師說:那么同學(xué)們誰能告訴我,為什么會出現(xiàn)這種問題?一生小聲說:還不是我們笨,不會寫。師說:不是笨,也不是不會寫,你們想為什么記敘文就會寫,一到議論文就不會了,那是因為同學(xué)們沒有明白議論文中的記敘與記敘文中的記敘有什么不同,所以一寫起議論文中的記敘,還是按照記敘文的寫法寫作,這自然就不行了。那好,今天我們就從如何寫議論文中的記敘講起。

當(dāng)代社會生活的變化比以往任何時代都要快。語言尤其是詞匯記錄了這些發(fā)展變化,因而也涌現(xiàn)了大量的新詞新語。據(jù)統(tǒng)計,近幾年每年大約要出現(xiàn)1000個左右的新詞新語,而字典、詞典的多次修訂、增補就反映了這種情況。但相對來說,也有一些流行語又逐漸受到冷遇,甚至退隱。為了更好的對新詞新語與流行文化作一番檢視與探究,那讓我們考察一下它們是怎么產(chǎn)生的吧?老師先給同學(xué)們列舉四種途徑:大屏幕3。同學(xué)們能再舉出以上途徑的一些例子嗎?老師列舉(4)其實不只這些,那還有哪些途徑呢?找同學(xué)說并舉例。說的非常好,請同學(xué)們看老師的例子,總結(jié)(5)。從新詞新語的產(chǎn)生途徑可以看出,這些鮮活得像畫一樣的新詞就是這個時代跳動的血小板,它涉及當(dāng)代社會的重大事件、現(xiàn)象與時弊,以及人們?nèi)粘I畹母鱾€層面如人生意義、生活方式、愛情、友情、就業(yè)、消費、時尚等,時代性強,傳播面廣,反映著當(dāng)代社會時局與人們文化心態(tài)的變化。

1、教材內(nèi)容本節(jié)是人教版普通高中標(biāo)準(zhǔn)實驗教科書生物必修2《遺傳與進化》的第五章《基因突變及其他變異》的第一節(jié)內(nèi)容。本節(jié)介紹了可遺傳變異的兩種類型:基因突變和基因重組,其中基因突變從實例對鐮刀型細(xì)胞貧血癥的分析入手,引入基因突變的概念,然后詳細(xì)闡述基因突變的原因和特點、意義。在闡述自然狀態(tài)下基因突變的頻率很低時,教材用實例說明在一個足夠大的群體中,即使基因突變頻率很低,突變個體仍然會占有一定的數(shù)量。這個實例體現(xiàn)了生物在進化過程中“變”與“不變”的平衡,有助于學(xué)生理解基因突變在生物進化中所占有的重要地位。在基因重組部分,教材設(shè)置了“思考與討論“的欄目,旨在讓學(xué)生利用數(shù)學(xué)方法,通過計算,體會基因重組機制提供的極其多樣的基因組合方式,從而幫助學(xué)生理解基因重組是生物多樣性形成的主要原因。正文中則簡要闡述了基因重組的概念、類型和意義。本節(jié)內(nèi)容引導(dǎo)學(xué)生從分子水平上理解遺傳物質(zhì)如何引起生物變異的。

一 減數(shù)分裂高一生物減數(shù)分裂說課稿各位評委、老師:大家好,我今天說課的題目是高中生物必修2第二章第一節(jié)〈〈減數(shù)分裂與受精作用〉〉第一部分減數(shù)分裂第一課時精子形成過程。接下來我就從以下幾個方面來說說這一節(jié)課。一、說教材1.教材地位和作用《減數(shù)分裂》這一部分內(nèi)容不僅是第二章的重點內(nèi)容,也是整本書的重點內(nèi)容之一。它以必修一學(xué)過的細(xì)胞學(xué)知識、染色體知識、有絲分裂知識和初中生殖種類知識為基礎(chǔ)。通過學(xué)習(xí),使學(xué)生全面認(rèn)識細(xì)胞分裂的種類、實質(zhì)和意義,為后面學(xué)習(xí)遺傳和變異,生物的進化奠定細(xì)胞學(xué)基礎(chǔ)。2.教學(xué)目標(biāo)(1)知識目標(biāo):掌握減數(shù)分裂的概念和精子的形成過程;理解減數(shù)分裂和受精作用的意義。(2)能力目標(biāo):通過觀察減數(shù)分裂過程中染色體的行為變化,培養(yǎng)學(xué)生識圖、繪圖能力以及比較分析和歸納總結(jié)的能力。
