教學(xué)反思

1.本節(jié)課課型是一節(jié)新授課，設(shè)計(jì)了一系列的聽(tīng)說(shuō)讀寫(xiě)教學(xué)任務(wù)，學(xué)生在師生互動(dòng)、生生互動(dòng)的過(guò)程中掌握了重點(diǎn)詞匯，較大數(shù)字的表達(dá)方法。

2.學(xué)生在經(jīng)過(guò)初步感知較大數(shù)字讀法及形容詞比較、最高級(jí)的拓展用法之后，探究、討論這些問(wèn)題，達(dá)到感知—理解—共鳴—吸收的課堂教學(xué)效果。

3.有效地運(yùn)用多媒體信息技術(shù)，實(shí)現(xiàn)了網(wǎng)絡(luò)與英語(yǔ)課程的整合。事實(shí)證明播放恰當(dāng)?shù)挠新曇曨l更具有感染力，更能激發(fā)學(xué)生的學(xué)習(xí)興趣。

4.由淺入深地呈現(xiàn)核心句式結(jié)構(gòu)和目標(biāo)語(yǔ)言，在各種比較中了解了一些有關(guān)世界之最和中國(guó)之最的地理知識(shí)。為了達(dá)到學(xué)以致用的目的，設(shè)計(jì)的家庭作業(yè)要求從中國(guó)悠久的歷史，龐大的人口數(shù)量，著名的長(zhǎng)江、黃河、高山、長(zhǎng)城等方面寫(xiě)一篇作文，這項(xiàng)活動(dòng)既整合了本節(jié)所學(xué)內(nèi)容，又培養(yǎng)了他們的愛(ài)國(guó)主義情操。

5.各個(gè)環(huán)節(jié)的教學(xué)都充分調(diào)動(dòng)了學(xué)生的學(xué)習(xí)主動(dòng)性，啟發(fā)學(xué)生思考問(wèn)題，在小組合作、探究中完成任務(wù)，教師適當(dāng)幫助，盡量不讓一名學(xué)生掉隊(duì)，使每名學(xué)生都成為課堂的主人。

總之，教師要為學(xué)生創(chuàng)設(shè)生動(dòng)活潑的語(yǔ)言環(huán)境，把學(xué)生吸引到活動(dòng)中去，激發(fā)他們主動(dòng)參與學(xué)習(xí)的欲望。按課堂需要取材，合理地拓展教材、整合教材，把情感態(tài)度與價(jià)值觀的教育巧妙地融入教學(xué)活動(dòng)中是我們每節(jié)課備課的一個(gè)重要方面。
