四、說教法、學(xué)法【說教法】1.美讀感悟法： 文章語言優(yōu)美，讀起來瑯瑯上口，因此，“美讀”是本課最重要，也是最主要的方法?！伴喿x是學(xué)生個(gè)性化的行為，不應(yīng)以教師的分析代替學(xué)生的實(shí)踐?！睂τ谌昙墝W(xué)生來說，更不必過多的講解分析，最主要讓學(xué)生多讀，同時(shí)教師要巧妙地借助課件，借助對學(xué)生讀書的評價(jià)，幫助學(xué)生在讀中去感受，領(lǐng)悟，使學(xué)生感受到語言文字中所描繪的鮮明形象，引起學(xué)生對課文中描述的事物與情景的關(guān)注，入境入情，促進(jìn)學(xué)生自悟自得，受到美的熏陶，激起觀察自然的興趣。 2.多媒體情景法： 因?yàn)樾W(xué)生生活經(jīng)驗(yàn)少，但好奇心強(qiáng)，容易激發(fā)興趣，因此，我運(yùn)用電教手段，創(chuàng)設(shè)多種情景，展示課文相關(guān)圖片，使學(xué)生在完全置身于課文所描繪的情景的同時(shí)，輕松、愉快、積極、主動的學(xué)習(xí)。同時(shí)，形象直觀的課件展示，有助于學(xué)生讀懂課文，感悟到語言文字帶來的美，體驗(yàn)到發(fā)現(xiàn)的樂趣，也有助于突出教學(xué)重點(diǎn)，突破教學(xué)難點(diǎn)。 3.質(zhì)疑問難法： 古人云：“學(xué)起于思，思源于疑?！闭n堂教學(xué)中，運(yùn)用恰當(dāng)?shù)氖侄危龑?dǎo)學(xué)生質(zhì)疑問難，能激發(fā)濃厚的思考興趣和創(chuàng)新思維。

一.說教材我今天說課的內(nèi)容是義務(wù)教育課程標(biāo)準(zhǔn)北師大版七年級下冊第四單元第二節(jié)的《用關(guān)系式表示的變量間關(guān)系》。在上節(jié)課的學(xué)習(xí)中學(xué)生已通過分析表格中的數(shù)據(jù)，感受到變量之間的相依關(guān)系，并用自己的語言加以描述，初步具有了有條理的思考和表達(dá)的能力，為本節(jié)的深入學(xué)習(xí)奠定了基礎(chǔ)。二.說教學(xué)目標(biāo)本節(jié)課根據(jù)新的教學(xué)理念和學(xué)生需要掌握的知識，確立本節(jié)課的三種教學(xué)目標(biāo)：知識與能力目標(biāo)：根據(jù)具體情況，能用適當(dāng)?shù)暮瘮?shù)表示方法刻畫簡單實(shí)際問題中變量之間的關(guān)系，能確定簡單實(shí)際問題中函數(shù)自變量的取值范圍，并會求函數(shù)值。過程與方法目標(biāo)：經(jīng)歷探索某些圖形中變量之間的關(guān)系的過程，進(jìn)一步體會一個(gè)變量對另一個(gè)變量的影響，發(fā)展符號感。情感態(tài)度與價(jià)值觀目標(biāo)：通過研究，學(xué)習(xí)培養(yǎng)抽象思維能力和概括能力，通過對自變量和因變量關(guān)系的表達(dá)，培養(yǎng)數(shù)學(xué)建模能力，增強(qiáng)應(yīng)用意識。
北師大版初中數(shù)學(xué)八年級下冊一元一次不等式與一次函數(shù)說課稿2篇
由于任何一個(gè)一元一次不等式都能寫成ax+b>0（或<0）的形式，而此式的左邊與一次函數(shù)y=ax+b的右邊一致，所以從變化與對應(yīng)的觀點(diǎn)考慮問題，解一元一次不等式也可以歸結(jié)為兩種認(rèn)識：⑴從函數(shù)值的角度看，就是尋求使一次函數(shù)y=ax+b的值大于（或小于0）的自變量x的取值范圍。⑵從函數(shù)圖像的角度看，就是確定直線y=ax+b在x軸上（或下）方部分所有的點(diǎn)的橫坐標(biāo)所構(gòu)成的集合。教學(xué)過程中，主要從以上兩個(gè)角度探討一元一次不等式與一次函數(shù)的關(guān)系。1、“動”―――學(xué)生動口說，動腦想，動手做，親身經(jīng)歷知識發(fā)生發(fā)展的過程。2、“探”―――引導(dǎo)學(xué)生動手畫圖，合作討論。通過探究學(xué)習(xí)激發(fā)強(qiáng)烈的探索欲望。3、“樂”―――本節(jié)課的設(shè)計(jì)力求做到與學(xué)生的生活實(shí)際聯(lián)系緊一點(diǎn)，直觀多一點(diǎn)，動手多一點(diǎn)，使學(xué)生興趣高一點(diǎn)，自信心強(qiáng)一點(diǎn)，使學(xué)生樂于學(xué)習(xí)，樂于思考。4、“滲”―――在整個(gè)教學(xué)過程中，滲透用聯(lián)系的觀點(diǎn)看待數(shù)學(xué)問題的辨證思想。

四、教學(xué)設(shè)想教學(xué)古代詩歌，一般的程式是介紹作者、時(shí)代背景、串講全詩、講寫作特點(diǎn)。本教學(xué)設(shè)計(jì)意在打破這樣的程式。如果能讓學(xué)生在學(xué)習(xí)《山居秋暝》中體會到欣賞詩歌的流程，將對后面的詩歌學(xué)習(xí)，起到示范作用。為此，我打算突破原先的那些教學(xué)模式，想結(jié)合正在進(jìn)行的研究性學(xué)習(xí)，充分發(fā)揮學(xué)生的主體作用，讓學(xué)生自己參與到整個(gè)教學(xué)過程中來，從而使他們對如何鑒賞詩歌有一個(gè)初步的框架。因?yàn)?，在教學(xué)中，我發(fā)現(xiàn)，現(xiàn)在的學(xué)生古典詩歌的積累是遠(yuǎn)遠(yuǎn)不夠的，他們?nèi)狈υ姼璧闹苯咏佑|，以前學(xué)習(xí)詩歌，更多的是聽老師的講解，去記住老師對詩歌的理解，到最后只是記住了一些詩歌鑒賞的語句，他們不是用自己的內(nèi)心去感悟一首詩。因此，我打算以《山居秋暝》作為一個(gè)突破口，作為鑒賞其他詩歌的一個(gè)范本，讓學(xué)生初步學(xué)會怎樣去欣賞一首詩，特別是山水詩。預(yù)習(xí)時(shí)，要求學(xué)生制作課件，并進(jìn)行評比，把好的課件進(jìn)行展示，以激發(fā)學(xué)生的學(xué)習(xí)興趣，充分利用多媒體的優(yōu)點(diǎn)，展示優(yōu)美的畫面，名家配樂朗誦，視聽結(jié)合，以引導(dǎo)學(xué)生走進(jìn)詩中、進(jìn)入角色，自己去悟詩、品詩，進(jìn)而培養(yǎng)他們的思維能力、感悟能力，使其學(xué)會鑒賞詩詞。
