    三、孟德爾遺傳規(guī)律的現(xiàn)代解釋①分離定律:在雜合體的細胞中,位于一對同源染色體上的等位基因,具有一定的獨立性;在減數(shù)分裂形成配子的過程中,等位基因隨同源染色體的分開而分離,獨立地隨配子遺傳給后代。②自由組合定律:位于非同源染色體上的非等位基因的分離或組合是互不干擾的;在減數(shù)分裂過程中,同源染色體的等位基因彼此分離的同時,非同源染色體上的非等位基因自由組合??偨Y(jié):再次強調(diào)孟德爾遺傳定律的現(xiàn)代解釋課堂練習(xí):書本31頁6、教學(xué)反思:本節(jié)課設(shè)置了一系列問題情境,層層設(shè)問,在學(xué)生答問、質(zhì)疑、討論過程中讓學(xué)生建構(gòu)新概念和新的知識體系,并通過教師及時掌握反饋信息,適時點撥、調(diào)節(jié),讓學(xué)生在推理判斷中培養(yǎng)良好的思維習(xí)慣和對知識的遷移能力,而且通過留出一定的時間讓學(xué)生提問,體現(xiàn)了以學(xué)生為主體的思想。

    四、說教學(xué)程序(一).溫故知新、導(dǎo)入新課復(fù)習(xí)提問:基因突變導(dǎo)致生物變異的原因是什么?回答:基因突變是基因結(jié)構(gòu)發(fā)生改變,從而使遺傳信息改變,使蛋白質(zhì)結(jié)構(gòu)改變、生物性狀改變,即生物發(fā)生了變異。那么,基因是什么?它和染色體又有何關(guān)系?回答:基因是有遺傳效應(yīng)的DNA片斷,染色體是DNA的載體,基因在染色體上呈線形排列。引出新知:對于一個生物體來說,正常情況下,其染色體的結(jié)構(gòu)和數(shù)量都是穩(wěn)定的。但在自然條件或人為因素的影響下,染色體的結(jié)構(gòu)和數(shù)量均會發(fā)生改變,從而導(dǎo)致生物性狀的改變,這就屬于染色體變異。(二).把握重點、突破難點重點的把握:1、染色體結(jié)構(gòu)的變異播放影片:貓叫綜合征幼兒。讓學(xué)生觀察: 患兒哭聲輕、音調(diào)高,很像貓叫。教師補充: 患兒的征狀---兩眼較低、耳位低下,存在著嚴(yán)重的智力障礙。闡述病因---染色體片段缺失

    (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?!吧钸h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)講授新課:1、講授重點:文化與經(jīng)濟、政治的關(guān)系。我首先帶領(lǐng)學(xué)生分析課本上的活動探究,了解日常生活中的常見活動,讓學(xué)生們觀看視頻材料幫助學(xué)生對文化活動、經(jīng)濟活動、政治活動進行辨別和分類。然后讓學(xué)生們舉例說明,綜合探究,最后通過集體討論得出文化與經(jīng)濟政治的關(guān)系:經(jīng)濟是基礎(chǔ),政治是經(jīng)濟的集中表現(xiàn),文化是經(jīng)濟和政治的反映,一定的文化由一定的經(jīng)濟和政治決定,又反作用于政治和經(jīng)濟。這個問題是本課重點。要引導(dǎo)學(xué)生循序漸進,集體討論,得出結(jié)論。2、突破難點:(1)文化與經(jīng)濟政治相互交融,在時代發(fā)展的進程中。首先播放上海世博會視頻,讓學(xué)生體會文化、經(jīng)濟、政治活動,另外我會引導(dǎo)學(xué)生積極舉生活中的事例,來說明問題,讓學(xué)生學(xué)會舉一反三,充分理解這一知識,讓學(xué)生明白文化與經(jīng)濟、政治的聯(lián)系,讓學(xué)生清楚文化滲透的力量有多大,幫助學(xué)生樹立反對文化霸權(quán)主義的意識。

    (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。

    人教版高中政治必修4時代的精神的精華說課稿

    (二)能力目標(biāo)培養(yǎng)學(xué)生運用哲學(xué)理論觀察、分析、處理社會問題的能力,增強學(xué)生的時代感。(三)情感、態(tài)度與價值觀目標(biāo)培養(yǎng)學(xué)生與時俱進的思想品質(zhì),讓學(xué)生關(guān)注時代、關(guān)注現(xiàn)實、關(guān)注生活,逐步樹立科學(xué)的世界觀、人生觀、價值觀。三、說教學(xué)重難點:時代精神的總結(jié)和升華是本框的難點,雖然學(xué)生在文化生活中學(xué)習(xí)了文化與經(jīng)濟政治的關(guān)系,但要讓學(xué)生得出哲學(xué)是時代精神的總結(jié)和升華,還要聯(lián)系前面關(guān)于哲學(xué)的基礎(chǔ)知識進行總結(jié)歸納,因此可能會難以把握,另外關(guān)于什么樣的哲學(xué)是真正的哲學(xué)的理解會稍有難度。社會變革的先導(dǎo)是本框的重點,一方面哲學(xué)源于時代,另一方面強調(diào)哲學(xué)反過來對時代又有重要的反作用,突出這一點能夠更好地激發(fā)學(xué)生學(xué)習(xí)哲學(xué)的熱情和信心,對于后面知識的學(xué)習(xí)是極為有益的,因此社會變革的先導(dǎo)這一目作重點處理。
