3、總結(jié)(這部分要5分鐘)學(xué)生在教師的提示和問(wèn)題的引導(dǎo)下，完成對(duì)本節(jié)課的知識(shí)的歸納和小結(jié)。利用簡(jiǎn)煉、清晰的語(yǔ)言，再一次的突出本節(jié)課的重點(diǎn)，起到畫龍點(diǎn)睛的作用，培養(yǎng)了學(xué)生的表達(dá)能力。4、鞏固練習(xí)(這部分要10分鐘)用大屏幕投影把題目投影在屏幕上，讓學(xué)生思考，然后回答。這部分安排10分鐘的時(shí)間，讓學(xué)生思考完成具有針對(duì)性的練習(xí)，進(jìn)行知識(shí)鞏固和教學(xué)效果反饋，及時(shí)糾正錯(cuò)誤的理解和片面的認(rèn)識(shí)。5、板書設(shè)計(jì)在板書中,我根據(jù)板書的“規(guī)范、工整和美觀”的要求，結(jié)合所學(xué)的內(nèi)容，設(shè)計(jì)了如圖所示的板書。在其中，注重了重、難點(diǎn)的突出，使學(xué)生對(duì)知識(shí)的結(jié)構(gòu)、層次、重點(diǎn)、難點(diǎn)一目了然，便于記憶和理解。四、效果分析對(duì)于反射的判斷，學(xué)生仍有可能出現(xiàn)錯(cuò)誤，如刺激坐骨神經(jīng)肌肉的收縮，教師應(yīng)強(qiáng)調(diào)沒(méi)有完整的反射弧結(jié)構(gòu)參與的不是反射。
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(wèn)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(wèn)題，引發(fā)學(xué)生的聯(lián)想和思考，以這種提問(wèn)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2染色體變異說(shuō)課稿
四、說(shuō)教學(xué)程序（一）.溫故知新、導(dǎo)入新課復(fù)習(xí)提問(wèn):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(duì)于一個(gè)生物體來(lái)說(shuō)，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(huì)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(diǎn)、突破難點(diǎn)重點(diǎn)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(bǔ)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
人教版高中地理必修2煤城焦作出路何在說(shuō)課稿
分析過(guò)焦作市的地理概況和產(chǎn)業(yè)優(yōu)勢(shì)后，就需要針對(duì)由于資源枯竭所帶來(lái)的問(wèn)題提出合理化的建議。既然是談經(jīng)濟(jì)轉(zhuǎn)型，就應(yīng)該將話題的范圍明確在這一領(lǐng)域內(nèi)。通過(guò)材料3的相關(guān)內(nèi)容，我們了解到焦作市需要在產(chǎn)業(yè)結(jié)構(gòu)調(diào)整、培育新的優(yōu)勢(shì)產(chǎn)業(yè)、增強(qiáng)綜合競(jìng)爭(zhēng)力等三個(gè)整改方針上下功夫。因而引導(dǎo)學(xué)生針對(duì)優(yōu)勢(shì)與不足提出建議，以三個(gè)整改方針為基準(zhǔn)，衡量建議的可行性是鍛煉學(xué)生解決此類問(wèn)題的有效途徑。在此我將教會(huì)學(xué)生的是解決問(wèn)題方法而非案例的內(nèi)容，正所謂“授之以魚，不如授之以漁”。接下來(lái)針對(duì)學(xué)生的建議和教材資料分析所羅列的10點(diǎn)整改思路，由學(xué)生自由發(fā)言提出看法，通過(guò)教師的指導(dǎo)和學(xué)生的討論，進(jìn)而確定經(jīng)濟(jì)轉(zhuǎn)型建議的具體方案。最后注意將建議與產(chǎn)業(yè)優(yōu)勢(shì)相對(duì)照，看建議是否都是圍繞著產(chǎn)業(yè)優(yōu)勢(shì)而提出的，這樣做會(huì)加深學(xué)生的印象，通過(guò)建議和優(yōu)勢(shì)的對(duì)應(yīng)關(guān)系，將不難找出此類問(wèn)題的解題思路。
