人教版高中生物必修3第三章第二節(jié)《生長(zhǎng)素的生理作用》說(shuō)課稿
強(qiáng)調(diào)重力對(duì)生長(zhǎng)素分布的影響，為下面的內(nèi)容講解做鋪墊，明確植物出現(xiàn)向光性與生長(zhǎng)素分布不均有關(guān)。復(fù)習(xí)舊知識(shí)，產(chǎn)生首因效應(yīng)，鞏固和加強(qiáng)記憶。通過(guò)植物向光性是生長(zhǎng)素分布較多而促進(jìn)生長(zhǎng)，進(jìn)而提出“對(duì)于植物來(lái)說(shuō)，生長(zhǎng)素是不是越多越好”這個(gè)問題，引發(fā)思考，鍛煉思維。說(shuō)明生長(zhǎng)素濃度對(duì)不同器官產(chǎn)生的影響不同，讓學(xué)生對(duì)這一情況有一個(gè)整體印象。結(jié)合數(shù)學(xué)知識(shí)逐步分析圖上各點(diǎn)和各曲線的含義，引導(dǎo)學(xué)生得出不同器官對(duì)生長(zhǎng)素濃度的敏感性順序，為解釋橫放植物“S”型生長(zhǎng)做鋪墊。通過(guò)對(duì)曲線的分析，得出低生長(zhǎng)素濃度起促進(jìn)作用，高濃度有抑制作用這種雙重性，并得出其雙重性表現(xiàn)。通過(guò)以上的分析和總結(jié)，對(duì)橫放植物“S”型生長(zhǎng)進(jìn)行解釋，達(dá)到首尾呼應(yīng)的效果。采用“蒙太奇”手法，引申到“太空中，橫放植物將會(huì)如何生長(zhǎng)”這個(gè)問題，引發(fā)學(xué)生的聯(lián)想和思考，以這種提問方式結(jié)課為下節(jié)課的開課做了鋪墊，掌握了主動(dòng)權(quán)。
人教版高中生物必修3第四章第一節(jié)《種群的特征》說(shuō)課稿
第二環(huán)節(jié)合作討論，獲得新的知識(shí)展示圖片，一塊草地上的全部蒲公英，估算所有蒲公英的數(shù)量，引出種群密度的概念?；氐絾栴}即調(diào)查蒲公英的種群密度，教師啟發(fā)，學(xué)生閱讀教材討論總結(jié)說(shuō)出樣方法，以問題承接“一片草地上的所有山羊”怎么知道其種群密度,激起學(xué)生認(rèn)知沖突，進(jìn)一步思考討論，得出標(biāo)志重捕法，教師引導(dǎo)學(xué)生完成標(biāo)志重捕法的概念、操作過(guò)程，計(jì)算公式，并與樣方法進(jìn)行比較。教師陳述“種群密度是種群最基本的數(shù)量特征，反應(yīng)種群在一定時(shí)期的數(shù)量，不能反應(yīng)種群的變化趨勢(shì)”引出反映種群變化趨勢(shì)的其他特征——出生率和死亡率，遷入和遷出，年齡組成和性別比例。學(xué)生討論總結(jié)這些特征的概念、對(duì)種群密度的影響及對(duì)生產(chǎn)生活實(shí)踐的指導(dǎo)意義。使學(xué)生認(rèn)同計(jì)劃生育國(guó)策，關(guān)注瀕危動(dòng)物的種群數(shù)量變化。之后引導(dǎo)學(xué)生構(gòu)建種群特征的關(guān)系圖。再簡(jiǎn)明闡述種群空間特征即：隨即分布，均勻分布、集群分布。第三環(huán)節(jié)反饋練習(xí)，鞏固新知識(shí)通過(guò)對(duì)學(xué)生練習(xí)結(jié)果的評(píng)價(jià)，了解學(xué)生對(duì)知識(shí)的掌握情況。即以學(xué)生為核心的教學(xué)評(píng)價(jià)。

人教版高中地理必修3地理環(huán)境對(duì)區(qū)域發(fā)展的影響說(shuō)課稿
本節(jié)課我分成兩個(gè)課時(shí)A首先我會(huì)在在ppt上放幾張關(guān)于區(qū)域的圖，讓學(xué)生思考什么是區(qū)域，區(qū)域有什么特征。其次我會(huì)在在書上畫出區(qū)域的定義，在給與解釋說(shuō)明，再在書上畫出區(qū)域的四個(gè)特征，讓同學(xué)小組討論哪些區(qū)域是有界的，哪些區(qū)域是無(wú)界的，從而加深同學(xué)們對(duì)區(qū)域的理解。B在ppt上放出長(zhǎng)江三角洲和松嫩平原，不同風(fēng)土人情由此導(dǎo)入下一個(gè)知識(shí)點(diǎn)：不同區(qū)域由于地理環(huán)境的差異，人們的生產(chǎn)特點(diǎn)有許多的不同，發(fā)展方式也存在差異，然后讓學(xué)生思考長(zhǎng)江三角洲和松嫩平原有什么差異，各自給區(qū)域環(huán)境發(fā)展帶來(lái)什么影響，啟發(fā)學(xué)生從氣候等方向思考，然后用表格的方式給不同因素歸類(歸位自然和社會(huì)經(jīng)濟(jì)兩大類)再啟發(fā)同學(xué)們從兩大類分別討論對(duì)農(nóng)業(yè)與工業(yè)發(fā)展的影響，最后再用表格的形式分類表達(dá)C然后給同學(xué)們幾個(gè)問題，鞏固同學(xué)課堂所學(xué)，最后留下一個(gè)問題課后解決：除了今天講的因素外還有哪些因素對(duì)區(qū)域發(fā)展產(chǎn)生影響?
