只有對儒家的價(jià)值作出客觀、公正、全面的評價(jià)，才可能避免陷入文化虛無主義或文化復(fù)古主義的誤區(qū)，合理地、充分地開發(fā)利用儒學(xué)乃至整個(gè)國學(xué)的資源為現(xiàn)代社會服務(wù)，為促進(jìn)我國經(jīng)濟(jì)發(fā)展服務(wù)。運(yùn)用所學(xué)知識，談?wù)剬Υ鍖W(xué)我們應(yīng)該持有的態(tài)度。答案：（1）儒學(xué)是我國傳統(tǒng)文化中一個(gè)非常重要的組成部分。傳統(tǒng)文化具有相對穩(wěn)定性，它的內(nèi)涵又能夠因時(shí)而變，因此，我們對待儒學(xué)的正確態(tài)度應(yīng)該是“取其精華，去其糟粕，批判繼承，古為今用”。（2）面對儒學(xué)，我們要辯證地認(rèn)識它在現(xiàn)實(shí)生活中的作用，分辨其中的精華和糟粕。對于其中符合社會發(fā)展要求的、積極向上的內(nèi)容，應(yīng)該繼續(xù)保持和發(fā)揚(yáng)，使其為社會主義現(xiàn)代化建設(shè)服務(wù)；對于其中不符合社會發(fā)展要求的、落后的、腐朽的東西，必須“移風(fēng)易俗”，自覺地加以改造和剔除。(五)作業(yè)布置傳統(tǒng)文化的作用是什么？如何正確對待傳統(tǒng)文化？
人教版高中歷史必修3輝煌燦爛的文學(xué)說課稿
教師：不同的時(shí)代造就了不同風(fēng)格和不同精神內(nèi)容的詩詞，請同學(xué)們回顧必修一和必修二兩宋中央集權(quán)的加強(qiáng)和經(jīng)濟(jì)的發(fā)展?fàn)顩r。學(xué)生：回憶回答。教師：請同學(xué)們結(jié)合時(shí)代背景和詞的特點(diǎn)理解詞為什么能夠成為宋代文學(xué)的主流形式和標(biāo)志？學(xué)生：兩宋時(shí)經(jīng)濟(jì)重心轉(zhuǎn)移到了南方，商業(yè)發(fā)展打破了時(shí)間和空間的限制，城市繁榮，市民數(shù)量不斷增加。詞的句子長短不齊，便于抒發(fā)感情，并且能夠歌唱，更能適應(yīng)市井生活的需要。于是，詞成為宋代文學(xué)的主流形式和標(biāo)志。教師：宋代文人地位提高，宋詞就是一個(gè)個(gè)時(shí)代的畫卷：大宋的悲歡離合都寫在了里面。除了詞之外，宋代民間還興起了一種新的詩歌形式，即散曲。學(xué)生：回答散曲的發(fā)展階段及特點(diǎn)、元曲的含義、特點(diǎn)。教師：在中國古代詩歌輝煌發(fā)展的同時(shí)，也產(chǎn)生了供人們閑來無事消遣的小說。
部編人教版六年級下冊《文言文二則》說課稿（二）
3.教學(xué)要求：知識能力訓(xùn)練點(diǎn)：學(xué)生通過教師引導(dǎo)以及小組自主合作，能根據(jù)課后注釋疏通全文，了解故事內(nèi)容。能有感情地朗讀課文，背誦課文，做到正確、節(jié)奏停頓得當(dāng)、抑揚(yáng)頓挫，從反復(fù)誦讀中初步感悟文言文中特殊的語言現(xiàn)象。過程方法引導(dǎo)點(diǎn)：通過教師引導(dǎo)，學(xué)生自悟自得，初步了解文言文學(xué)習(xí)的方法。（根據(jù)注釋、聯(lián)系上下文讀通、讀懂、熟讀成誦。）情感態(tài)度滲透點(diǎn)：學(xué)生能從文中體會到做事必須專心致志，不可三心二意的道理。能從課內(nèi)外延伸結(jié)合中進(jìn)一步了解我國輝煌燦爛的古代文化，增加學(xué)生學(xué)習(xí)語文的興趣，全面提高學(xué)生語文綜合素養(yǎng)。4.教學(xué)重難點(diǎn)：古文與現(xiàn)代白話文相比，在用詞造句上截然不同，能否正確地?cái)嗑?，流利地朗讀，是首先遇到的困難。因此要把指導(dǎo)學(xué)生朗讀和背誦作為本課教學(xué)重點(diǎn)。從理解課文方面看，難點(diǎn)在于讓學(xué)生參考課后注釋讀懂每句話的意思，整體感知課文內(nèi)容，所以要將此點(diǎn)作為難點(diǎn)來突破。由此可見，兩者相輔相成，互相滲透，而利用CAI課件為學(xué)生提供形象生動的畫面，創(chuàng)設(shè)情境加強(qiáng)對學(xué)生朗讀的指導(dǎo)是突破本課教學(xué)重難點(diǎn)的關(guān)鍵。

二、教學(xué)目標(biāo)：1、知識與能力（1）了解我國古代冶金、制瓷、絲織業(yè)發(fā)展的基本情況；（2）了解中國古代手工業(yè)享譽(yù)世界的史實(shí)，培養(yǎng)學(xué)生的民族自信心。2、過程與方法（1）通過大量的歷史圖片，指導(dǎo)學(xué)生欣賞一些精湛的手工業(yè)藝術(shù)品，提高學(xué)生探究古代手工業(yè)的興趣；（2）運(yùn)用歷史材料引導(dǎo)學(xué)生歸納古代手工業(yè)產(chǎn)品的基本特征。3、情感態(tài)度與價(jià)值觀：通過本課教學(xué)，使學(xué)生充分地感受到我國古代人民的聰明與才智，認(rèn)識到古代許多手工業(yè)品具有較高的藝術(shù)價(jià)值，以及在世界上的領(lǐng)先地位和對世界文明的影響，增強(qiáng)民族自豪感。

強(qiáng)調(diào)重力對生長素分布的影響，為下面的內(nèi)容講解做鋪墊，明確植物出現(xiàn)向光性與生長素分布不均有關(guān)。復(fù)習(xí)舊知識，產(chǎn)生首因效應(yīng)，鞏固和加強(qiáng)記憶。通過植物向光性是生長素分布較多而促進(jìn)生長，進(jìn)而提出“對于植物來說，生長素是不是越多越好”這個(gè)問題，引發(fā)思考，鍛煉思維。說明生長素濃度對不同器官產(chǎn)生的影響不同，讓學(xué)生對這一情況有一個(gè)整體印象。結(jié)合數(shù)學(xué)知識逐步分析圖上各點(diǎn)和各曲線的含義，引導(dǎo)學(xué)生得出不同器官對生長素濃度的敏感性順序，為解釋橫放植物“S”型生長做鋪墊。通過對曲線的分析，得出低生長素濃度起促進(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)。通過以上的分析和總結(jié)，對橫放植物“S”型生長進(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，橫放植物將會如何生長”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，掌握了主動權(quán)。
人教版高中生物必修3第四章第二節(jié)《種群數(shù)量的變化》說課稿
4、種群數(shù)量變化的其他類型我結(jié)合“種群數(shù)量下降”這個(gè)知識點(diǎn)對學(xué)生進(jìn)行寓教?，F(xiàn)今的自然界，許多野生生物種群的數(shù)量都在下降，為什么呢？我提供了世界人口近2000年的種群增長曲線，一切都在不言而喻中。現(xiàn)今社會的主題是呼吁建立和諧社會，作為生物老師，我想它不應(yīng)該僅僅指人與人之間的和諧，也不應(yīng)該僅僅指人與社會之間的和諧，它更應(yīng)該昭示著人與自然之間的和諧，人類只有學(xué)會與自然和諧相處，才能在生物圈中享受最大的幸福。6、小結(jié)課程在實(shí)驗(yàn)的大背景下展開，也在實(shí)驗(yàn)的背景中結(jié)束，這里可以呈現(xiàn)出一個(gè)完整的探究思路。同時(shí)，學(xué)生思考如何實(shí)現(xiàn)多種預(yù)期過程，相當(dāng)于對本課進(jìn)行小結(jié)。五、效果預(yù)測課堂上選取的內(nèi)容基于學(xué)生的生活體驗(yàn)，創(chuàng)設(shè)的情境能激發(fā)學(xué)生的興趣，設(shè)置的問題符合學(xué)生的認(rèn)知水平，有助于學(xué)生能力的提高，教學(xué)目標(biāo)可以基本實(shí)現(xiàn)。

1.潛在價(jià)值──某種不知名的昆蟲。間接價(jià)值──每個(gè)物種都維系著它們所在的生態(tài)系統(tǒng)的結(jié)構(gòu)和功能。直接價(jià)值──蘆葦是一種重要的造紙?jiān)?；蟬蛻是一種動物性藥物；魯班通過觀察某種葉片的葉緣得到啟示，研制出了木工用的鋸；海洋和森林等生態(tài)系統(tǒng)能陶冶情操、激發(fā)創(chuàng)作的靈感。2.主要的困難是，一些發(fā)達(dá)國家（如美國、加拿大和歐盟國家等），拒絕核準(zhǔn)或遲遲不予核準(zhǔn)該議定書。主要爭議的問題是，這些國家擔(dān)心影響本國經(jīng)濟(jì)的發(fā)展和其他國家可能不承擔(dān)相應(yīng)的責(zé)任。例如，美國政府在2003年3月以“減少溫室氣體排放將會影響美國經(jīng)濟(jì)發(fā)展”和“發(fā)展中國家也應(yīng)該承擔(dān)減排和限排溫室氣體的義務(wù)”為由，宣布拒絕執(zhí)行《京都議定書》。建議世界各國特別是發(fā)展中國家聯(lián)合起來，通過聯(lián)合國大會和各國的政府以及民間組織等多種途徑，呼吁每年大量產(chǎn)生溫室氣體的發(fā)達(dá)國家率先核準(zhǔn)《京都議定書》（我國政府早在2002年9月就核準(zhǔn)了《京都議定書》）。

（四）、活動交流，體驗(yàn)科學(xué)通過資料分析討論以下三個(gè)問題：1、你知道愛滋病的傳播途徑嗎？2、如何預(yù)防愛滋??？3、我們應(yīng)如何對待愛滋病患者？面對艾滋病我們能做些什么？從而進(jìn)入情感態(tài)度的教育。除此之外，我還設(shè)計(jì)一個(gè)開放性的作業(yè)“向全社會為關(guān)注艾滋病設(shè)計(jì)一個(gè)宣傳廣告”（形式不限，漫畫、板書、倡議書等），讓學(xué)生把愛心付諸于實(shí)際行動。在此基礎(chǔ)上引出“免疫學(xué)的應(yīng)用”從免疫預(yù)防、免疫治療、器官移植三個(gè)方面講述，讓學(xué)生充分體驗(yàn)到知識和社會生活的緊密聯(lián)系，讓他們不在感到科學(xué)是那么的遙遠(yuǎn)，而是可愛的有用的。通過交流，讓同學(xué)們體會到合作的魅力和重要性，進(jìn)一步培養(yǎng)合作意識和合作能力。最后我設(shè)計(jì)一個(gè)資料搜集，讓同學(xué)們選一個(gè)感興趣的主題利用電腦在網(wǎng)上搜集有關(guān)資料。主題：1、你知道世界艾滋病日嗎？歷年的主題是什么？開展世界艾滋病運(yùn)動有什么意義？
人教版高中地理必修1第二章第三節(jié)常見的天氣系統(tǒng)說課稿
一、說教材（一）教材的地位與作用本節(jié)內(nèi)容是本單元知識結(jié)構(gòu)中重要的一環(huán)，具有承上啟下的作用。由于各種天氣現(xiàn)象的產(chǎn)生與大氣的熱力狀況、大氣的運(yùn)動有密切的聯(lián)系，所以，本課是在綜合前兩節(jié)內(nèi)容的基礎(chǔ)上，闡述常見的天氣現(xiàn)象的成因。在實(shí)際生活中，天氣系統(tǒng)與人們的生產(chǎn)、生活密切相關(guān)。本課所講的內(nèi)容對于學(xué)生了解天氣變化的最基本因素，普及天氣預(yù)報(bào)知識具有積極的意義。（二）教學(xué)目標(biāo)(1)知識與技能目標(biāo)：⑴從圖片和簡易圖中，知道氣團(tuán)（冷氣團(tuán)、暖氣團(tuán)）的概念；鋒的概念與分類；低壓（氣旋）、高壓（反氣旋）、高壓脊、低壓槽的概念。 ⑵從氣溫、氣壓、濕度、降水、風(fēng)等幾方面分析各種天氣系統(tǒng)的形成及其氣流特點(diǎn)，并綜合出各種天氣系統(tǒng)控制下的天氣狀況。⑶知道低壓槽和高壓脊概念及在圖上的表示方法。(2)過程與方法目標(biāo)：⑴讓學(xué)生能閱讀和簡單分析天氣圖，解釋天氣變化現(xiàn)象；⑵用案例說明氣象災(zāi)害發(fā)生的原因和危害；
