  • 人教版高中生物必修1細(xì)胞的衰老與凋亡說課稿

    人教版高中生物必修1細(xì)胞的衰老與凋亡說課稿

    4、最后從生物的壽命引入,探討細(xì)胞的死亡。強調(diào)細(xì)胞死亡有兩種形式。(1).細(xì)胞壞死,它是由某些外界因素造成細(xì)胞急速死亡,是一種被動性死亡;(2).細(xì)胞凋亡,這是一種由特定基因控制的主動性死亡。細(xì)胞壞死與細(xì)胞凋亡在形態(tài)學(xué)和生物化學(xué)上有著明顯的區(qū)別。細(xì)胞凋亡有廣泛的生物學(xué)意義,比如胚胎發(fā)育期手的發(fā)育如果沒有細(xì)胞的調(diào)亡就不會有纖細(xì)的手指;如果沒有正常的細(xì)胞調(diào)亡,蝌蚪的尾部就不會消失,它將永遠(yuǎn)不能變成青蛙……。正常的細(xì)胞調(diào)亡還肩負(fù)著維持各種組織器官固有體積和形態(tài)的功能;還會使機體內(nèi)異常的細(xì)胞得到及時清除,去處潛在的隱患;例如癌癥就是異常的細(xì)胞沒有及時死亡的結(jié)果……。因此細(xì)胞的正常死亡是生物體的一種非常重要的調(diào)節(jié)機制,是機體平衡細(xì)胞增殖,調(diào)節(jié)機體細(xì)胞樹木恒定的方式,是必不可少的生命過程。(15分鐘)5、課堂小結(jié),可以把課堂傳授的知識盡快地轉(zhuǎn)化為學(xué)生的素質(zhì);簡單扼要的課堂小結(jié),可使學(xué)生更深刻地理解政治理論在實際生活中的應(yīng)用,并且逐漸地培養(yǎng)學(xué)生具有良好的個性。

    人教版高中地理必修3能源資源的開發(fā)—以我國山西省為例說課稿

    指導(dǎo)學(xué)生閱讀圖3.8,讓同學(xué)們討論山西省三類工業(yè)發(fā)展變化的情況??梢钥闯?,采掘業(yè)占工業(yè)增加值的比重在1985~1995年間有所上升,但在1995~2000年下降,且下降速度很快。原料工業(yè)始終在增加,且有越來越快的趨勢。加工工業(yè)1985~1995年間比重下降,到2000年幾乎停滯不前。這說明山西省雖然實現(xiàn)了產(chǎn)業(yè)結(jié)構(gòu)的升級,但還是限于初級加工階段,工業(yè)發(fā)展水平還不高。山西省只是一個能源大省,并不是一個工業(yè)大省,更不是經(jīng)濟強省,山西省的改革還有很長的路要走。(參考資料)《急需調(diào)整產(chǎn)業(yè)結(jié)構(gòu)的山西經(jīng)濟》(山西日報1999年11月25日)山西能源的綜合利用是一個正在發(fā)展完善的過程,教學(xué)中教師可以結(jié)合目前存在的一些問題和困境展開討論,引導(dǎo)學(xué)生深入探究。(例如屢屢發(fā)生的礦難,以及背后隱藏的“官煤勾結(jié)”問題,這些都是目前各種媒體關(guān)注的焦點,相關(guān)的新聞報道,教師在課前應(yīng)該專門搜集一些,或者讓有條件上網(wǎng)的學(xué)生自己去搜集,使得課堂教學(xué)更加貼近現(xiàn)實生活。)

    人教版高中歷史必修1世界多極化趨勢的出現(xiàn)說課稿2篇

    (一)本課教材地位分析本課教材的主題是世界格局多極化趨勢的出現(xiàn),在整個單元中有承前啟后的作用,前一課是它的大背景,后一課是它的延續(xù)。本課的核心問題是兩極格局下,20世紀(jì)六七十年代世界多極化趨勢的出現(xiàn)。通過走向聯(lián)合的歐洲、迅速崛起的日本、發(fā)展中國家的星期以及中國的崛起三方面內(nèi)容,反映了世界格局多極化趨勢的出現(xiàn)。在教學(xué)中,應(yīng)注意利用學(xué)生對時事的關(guān)心與熟悉,引導(dǎo)學(xué)生進(jìn)行相應(yīng)的探究活動,使學(xué)生對世界格局的發(fā)展變化能夠認(rèn)識準(zhǔn)確和完整把握。(二)三維目標(biāo)A.知識與能力1.通過對歐洲一體化的進(jìn)程、日本經(jīng)濟迅速崛起、不結(jié)盟運動和中國振興的基本史實的學(xué)習(xí),掌握20世紀(jì)六七十年代世界多極化趨勢出現(xiàn)的史實,理解其世界大背景和“多極化”的概念。2.通過西歐、日本、中國的崛起,理解經(jīng)濟決定政治,政治反作用于經(jīng)濟。

    人教版高中政治必修2世界多極化-不可逆轉(zhuǎn)說課稿

    環(huán)節(jié)四 課堂小結(jié) 鞏固知識 本節(jié)課我采用線索性的板書,整個知識結(jié)構(gòu)一目了然,為了充分發(fā)揮學(xué)生在課堂的主體地位,我將課堂小結(jié)交由學(xué)生完成,請學(xué)生根據(jù)課堂學(xué)習(xí)的內(nèi)容,結(jié)合我的板書設(shè)計來進(jìn)行小結(jié),以此來幫助教師在第一時間掌握學(xué)生學(xué)習(xí)信息的反饋,同時培養(yǎng)學(xué)生歸納分析能力、概括能力。環(huán)節(jié)五 情景回歸,情感升華我的實習(xí)指導(dǎo)老師告訴過我們,政治這一門學(xué)科要從生活中來到生活去,所以在課堂的最后布置課外作業(yè),以此培養(yǎng)學(xué)生對理論的實際運用能力,同時檢驗他們對知識的真正掌握情況,以此達(dá)到情感的升華,本節(jié)課,我根據(jù)建構(gòu)主義理論,強調(diào)學(xué)生是學(xué)習(xí)的中心,學(xué)生是知識意義的主動建構(gòu)者,是信息加工的主體,要強調(diào)學(xué)生在課堂中的參與性、以及探究性,不僅讓他們懂得知識,更讓他們相信知識,并且將知識融入到實踐當(dāng)中去,最終達(dá)到知、情、意、行的統(tǒng)一。
