1、全國中小學(xué)“教學(xué)中的互聯(lián)網(wǎng)搜索”優(yōu)秀教學(xué)案例評選教案設(shè)計(jì)一、 教案背景1，面向?qū)W生： 中學(xué) 2，學(xué)科：英語2，課時(shí)：13，學(xué)生課前準(zhǔn)備：1）、自學(xué)本課單詞，讀準(zhǔn)單詞的讀音。2）、初讀課文，了解課文大意。3） 小組討論P(yáng)re-reading question.二、 教學(xué)課題使學(xué)生了解噪音污染及危害，培養(yǎng)學(xué)生的環(huán)保意識(shí)。1、學(xué)習(xí)并掌握單詞15個(gè)。2、朗讀課文并背誦課文。3、感受噪音污染的危害，讓學(xué)生充分意識(shí)到噪音污染的嚴(yán)重性。4、培養(yǎng)學(xué)生的閱讀理解能力。三、 教材分析Section C主要是圍繞“噪音污染”這一問題展開學(xué)習(xí)的，使學(xué)生了解什么是噪音污染以及它們的危害，內(nèi)容貼近學(xué)生生活，為學(xué)生用英語進(jìn)

2、行交流提供了一個(gè)很好的平臺(tái)教學(xué)重點(diǎn)： （1）重點(diǎn)詞匯deaf， coal，print, disturb, including, rubbish etc。 （2）重點(diǎn)句型 not all表部分否定； no + 比較級(jí) + than（3）語法： 幫助學(xué)生了解幾個(gè)定語從句。 教學(xué)難點(diǎn)： （1）如何提高學(xué)生的閱讀理解能力。（2）對噪音污染的了解和討論，呼吁和倡議人類樹立環(huán)保意識(shí)。教學(xué)準(zhǔn)備：多媒體課件。1、Section C 的圖或錄象片，在百度中搜索本課課件，并對其進(jìn)行選擇、整理，制作成PPT課件用于課堂教學(xué)。2、課前查閱有關(guān)噪音污染的資料。教學(xué)之前用百度在網(wǎng)上搜索噪音污染的相關(guān)教學(xué)材料，找了很多教案

3、作參考，了解到教學(xué)的重點(diǎn)和難點(diǎn)，確定課堂教學(xué)形式和方法。然后根據(jù)課堂教學(xué)需要，利用百度搜索找到課文的朗讀錄音學(xué)習(xí)參考，課堂上帶領(lǐng)學(xué)生朗讀課文。用百度在網(wǎng)上搜索下載一個(gè)本課的視頻課件，課堂放給同學(xué)們看，給學(xué)生視覺、聽覺上的直觀感受。讓同學(xué)們對噪音污染產(chǎn)生切身體驗(yàn)。還下載了幾個(gè)PPT課件重新設(shè)計(jì)制作適用的課件。使之更為適合課堂使用。四、 教學(xué)方法本課屬于閱讀訓(xùn)練課，為了突出教學(xué)重點(diǎn)，在教學(xué)中我把讀貫穿全文。在朗讀教學(xué)中采用了跟讀、齊讀、賽讀等，每讀一次后給其任務(wù)型活動(dòng)，從而使學(xué)習(xí)氣氛活躍，收到了預(yù)期的教學(xué)效果。五、 教學(xué)過程 Unit2 Topic1 Section C Step 1 Review
