二、教法分析為了讓學(xué)生較好掌握本課內(nèi)容，本節(jié)課主要采用觀察法、討論法等教學(xué)方法，通過(guò)創(chuàng)設(shè)情境，使學(xué)生由淺到深，由易到難分層次對(duì)本節(jié)課內(nèi)容進(jìn)行掌握。三、學(xué)法分析本課要求學(xué)生通過(guò)自主地觀察、討論、反思來(lái)參與學(xué)習(xí)，認(rèn)識(shí)和理解數(shù)學(xué)知識(shí)，學(xué)會(huì)發(fā)現(xiàn)問(wèn)題并嘗試解決問(wèn)題，在學(xué)習(xí)活動(dòng)中進(jìn)一步提升自己的能力。四、教學(xué)過(guò)程創(chuàng)設(shè)問(wèn)題情景，引入新課活動(dòng)內(nèi)容：尋找不等的量 課本例一，例二設(shè)計(jì)目的：學(xué)生體會(huì)在現(xiàn)實(shí)生活中除了存在許多等量關(guān)系外，更多的是不等關(guān)系的存在，并通過(guò)感受生活中的大量不等關(guān)系，初步體會(huì)不等式是刻畫(huà)量與量之間關(guān)系的重要數(shù)學(xué)模型。經(jīng)歷由具體實(shí)例建立不等式模型的過(guò)程，進(jìn)一步發(fā)展學(xué)生的符號(hào)感與數(shù)學(xué)化的能力。課本例四，例五設(shè)計(jì)目的：培養(yǎng)學(xué)生數(shù)學(xué)抽象能力，提高把實(shí)際問(wèn)題轉(zhuǎn)化為數(shù)學(xué)問(wèn)題的能力。六.課堂小結(jié)體會(huì) 常量與常量間的不等關(guān)系變量與常量間的不等關(guān)系變量與變量間的不等關(guān)系
北師大版初中數(shù)學(xué)八年級(jí)下冊(cè)一元一次不等式組說(shuō)課稿2篇
1.通過(guò)實(shí)例體會(huì)一元一次不等式組是研究量與量之間關(guān)系的重要模型之一。2.了解一元一次不等式組及解集的概念。3.會(huì)利用數(shù)軸解較簡(jiǎn)單的一元一次不等式組。4.培養(yǎng)學(xué)生分析、解決實(shí)際問(wèn)題的能力。5.通過(guò)實(shí)際問(wèn)題的解決，體會(huì)數(shù)學(xué)知識(shí)在生活中的應(yīng)用，激發(fā)學(xué)生的學(xué)習(xí)興趣。能在解決問(wèn)題過(guò)程中勤于思考、樂(lè)于探究，體驗(yàn)解決問(wèn)題策略的多樣性,體驗(yàn)數(shù)學(xué)的價(jià)值。四、教學(xué)重、難點(diǎn)分析教學(xué)重點(diǎn)：1.理解有關(guān)不等式組的概念.2.會(huì)解由兩個(gè)一元一次不等式組成的不等式組.教學(xué)難點(diǎn)：在數(shù)軸上確定解集.五、教學(xué)手段分析本節(jié)課采用多媒體教學(xué)，利用多媒體教學(xué)信息容量大、操作簡(jiǎn)單、形象生動(dòng)、反饋及時(shí)等優(yōu)點(diǎn)，直觀地展示教學(xué)內(nèi)容，這樣不但可以提高學(xué)習(xí)效率和質(zhì)量，而且容易激發(fā)學(xué)生學(xué)習(xí)的興趣，調(diào)動(dòng)積極性。
