同課異構(gòu)教案：八上M3U2

1、 Unit 2. We havent found life on other planets yet.（初中英語外延版八年級上冊Module 3 Journey to space ）南寧市第三十一中學(xué) 黃玲鮮一、教材分析 本模塊以人類探索宇宙的行為為背景引入現(xiàn)在完成時的用法，通過人類對宇宙太空所做努力的描述，強化現(xiàn)在完成時表達意思的功能，開展聽說讀寫教學(xué)活動。教學(xué)內(nèi)容為語法的學(xué)習(xí)和使用提供了必要的感性材料。本模塊的中心話題是介紹航天知識，著重介紹了火星探索計劃以及宇宙中太陽系的部分知識。要求學(xué)生能夠了解一點航天知識，學(xué)會利用現(xiàn)在完成時描述人類已經(jīng)實施的太空探索計劃。 二、學(xué)情分析在前一個模塊“

2、Experiences”的學(xué)習(xí)中，學(xué)生初步掌握了利用現(xiàn)在完成時談?wù)撀糜?、看電影等?jīng)歷，學(xué)習(xí)了現(xiàn)在完成時的一般疑問句及肯定、否定的回答方法。在本模塊中，學(xué)生將繼續(xù)學(xué)習(xí)yet, already, just, recently等詞在現(xiàn)在完成時態(tài)中的用法, 以及have been to與 have gone to之間的區(qū)別。人類探索宇宙，是否真的存在外星人，太空旅行這些一直都是學(xué)生們非常感興趣的話題，學(xué)生會覺得有話可說。但是在討論這一話題時將涉及較多的專有名詞，學(xué)生掌握的難度較大。所以如果教材內(nèi)容處理不當(dāng)，會導(dǎo)致學(xué)生有話想說，卻無法用英語來表達的尷尬場面。因此在具體安排教學(xué)內(nèi)容時，應(yīng)注意適當(dāng)降低難度與

3、要求，通過開展生動有趣的活動將航天知識深入淺出的傳授給學(xué)生。三、班情分析初二（2）班，47人，絕大多數(shù)學(xué)生來自進城務(wù)工人員家庭（鄉(xiāng)村孩子在城里上學(xué)），小學(xué)階段學(xué)過英語的較少，英語基礎(chǔ)較弱，另一方面，這些孩子的父母整天忙于做生意，沒有時間和精力管理小孩，因而學(xué)生的行為習(xí)慣較差，學(xué)習(xí)的自覺性和學(xué)習(xí)能力都比較差，晚上在家完成作業(yè)的時間得不到保證。初二（6）班，51人，絕大多數(shù)學(xué)生是我校地段生（城里孩子），家庭對孩子的期望較高，多數(shù)孩子的父母晚上能在家看管孩子的學(xué)習(xí)，學(xué)生晚上的學(xué)習(xí)時間得到保證，完成家庭作業(yè)情況較好，學(xué)習(xí)自覺性和學(xué)習(xí)能力得到不斷的提升。對待這樣兩種截然不同的班級，老師授課的方式方法及對

4、學(xué)生的要求也要迥然不同才行。三、本節(jié)課師生共用的導(dǎo)學(xué)案（已經(jīng)堅持使用一個多學(xué)期）八上 Module 3 Journey to space Unit 2.
