Unit 4 When was it invented 教学设计


Unit4Whenwasitinvented(Reading)---

Doyouknowwhenbasketballwasinvented

教学设计

一教材分析

教材分析:本节课是九年级Unit4的Reading部分。本节课的主题是:Doyouknowwhenbasketballwasinvented?紧扣住了本单元的话题invention。课文内容主要围绕风靡全球的篮球运动这一主题,包括篮球运动的历史、篮球比赛的规则、打篮球所需的设备、篮球的流行趋势等)。本单元的语法点是被动语态。文中出现了大量的被动语态的句子,通过阅读文章,学生能有效的感悟被动语态的用法。本节课渗透得的学习策略是mind-map,希望通过本节课的学习,学生能对该策略形成感性认识,并在今后的学习中能有意识的使用该学习策略。

二、学生分析

通过本单元前面内容的学习,学生已经基本掌握了被动语态的用法,因此本篇阅读中出现的多处被动语态的句子对学生来说已不是障碍,关键的障碍是本文中出现的一些生词,需要学生认读,否则在回答问题是就是障碍。运用Mind-mapping是复述课文的信息对学生来说是一大难点。

三、教学目标、

1知识目标

①能认读以下词汇

active,indoors,create,wooden,knock,divide,basket,metal,towards,develop,rise,risen,worldwide

②找出并理解文章中出现的被动语态的句子。

2能力目标

能运用Mind-mapping复述篮球的历史、篮球的器械、篮球的规则、篮球的流行趋势等。

3情感目标

激发学生对运动的热爱,并让学生树立teamwork的意识。

四、教学重、难点

1、教学重点

能认读以下词汇:active,indoors,create,wooden,knock,divide,basket,metal,towards,develop,rise,risen,worldwide

②找出并理解文章中出现的被动语态的句子。

2教学难点

能运用Mind-mapping复述篮球的历史、篮球的器械、篮球的规则、篮球的流行趋势等。

五、教具:多媒体

六、学习策略:小组合作学习、大脑构图法

七、教学活动过程

Step1Warm-up

Aninterestinggame-------That’sme.

Step2Pre-reading

1、Asksomequestionsaboutbasketballgame.

2、ShowapictureofbasketballequipmentandthenleadSstoreadthewordsaboutbasketequipment.

Step3While-reading

1、Fast-reading

AskSstoreadfastandmatcheachparagraphwiththemainmeaning

2、Careful-reading

①AskSstoreadPara1andPara2andthenfinishthechartwithinformationaboutbasketballisplayedintheworld.

②AskSstoreadpara3andanswersomequestions.

③AskSstocirclethepassivevoiceinPara3.

④AskSstoreadPara4andthenfillinthechartwiththeinformationabouttheinventionofbasketball,theequipmentofbasketballandthecourseofbasketballgame.

⑤AskSstoreadPara5andthenfillinthechartwiththeinformationaboutthehistoryofbasketballgame.

Step4After-reading

4、AskSstorewritePara1andPara2accordingtothemind-map.

5、Discussion:“What’sthemostimportantforateamtowinthegame?“-------------Teamwork.

Step5Homework

1、Copythesentencesofpassivevoiceinthispassage.(ForAll)

2、Makeamind-mapabouthehistoryofasportyoulike

八、教学反思

本人设计本课时的教学任务时始终围绕“basketball”这一话题和预设的教学目标。在Warm-up环节,通过“That’sme”游戏中的陈述轻松引入“basketball”这一话题。Pre-reading环节中,通过和学生谈论basketball的一些常识,激发学生对篮球的深入了解,然后让学生通过图片了解关于篮球器材的词汇,达到认读的目的,为接下来的阅读任务扫除大部分单词的障碍,剩下的少数词汇在接下来的任务中分散完成认读任务。While-reading环节中,首先让学生通过完成Fast-reading的任务,整理理解语篇,了解文章的大意和层次。然后让学生完成Careful-reading的多个阅读任务,细读各个段落,详细了解有关篮球和篮球运动的历史并体会学习被动语态的用法。在After-reading环节,让学生学习本节课的重要学习策略-脑中构图法,然后用这一策略完成一系列由易到难的几个任务,达到“学以致用”,在使用这一策略的过程中学生能够体会到“脑中构图法”的绝妙之处----能帮助学习者轻松梳理较长篇幅文章中的信息并帮助快速记住这些信息。这种方法比起用表格梳理信息更直观。最后让学生在谈论篮球比赛中获胜的关键是什么这一话题时总结出teamwork是最重要的,完成情感目标。家庭作业分层设计,第一个作业是必做,巩固被动语态,第二个作业是选做,继续用“脑中构图法”这一学习策略完成任务。在本节课教学任务的设计应该是到位的,通过完成Pre-reading,While-reading,After-reading各环节中的阅读任务,能够达到完成预设的教学目标的目的。不足之处是本篇阅读材料篇幅较长,设计的任务过多,一节课完成这些任务容量过大,所以最后需用“脑中构图法”完成的任务当堂没有完成,只得推到课后。今后应该更好地了解学情,对课堂容量做到心中有数,设计适当,课堂任务的设计不能面面俱到,应有所侧重,取舍得当,留给学生足够的阅读时间和完成任务的时间,让课堂任务真正到达有实效。

典型例题解析:

1.--Whataniceclassroom!--It____everyday.

A.iscleaningB.hascleanedC.mustcleanD.iscleaned

解析:推测这句话的意思应该是“它每天都被打扫”,考查被动语态的结构be+动词的过去分词。因此答案应该选D。

2.IknowBeijingwell.I____therethreetimes.

A.willgoB.havebeenC.wentD.havegone

解析:推测这句话的意思“我很了解北京,我去过那三次”。表示去过应该采用的时态是现在完成时,因此可排除A和C,区别havebeen和havegone,havebeen去过;havegone去了(还没回来)。因此应该选择B。
