Module3 Unit2第二课时教学设计 外研版英语八年级下册

基于课程标准的“教学评一体化”设计课时备课课题八下Module3JourneytospaceUnit2日期课时2课型读写授课教师目标确立依据课标分析课标摘录义务教育《英语课程标准》语言技能四级标准：读：1.能读懂简单的个人信件、说明文等应用文体材料；写：2.能在教师的帮助下或以小组讨论的方式起草和修改作文；语言知识四级标准：语法：1.理解现在完成时并能在特定语境中使用；3.在实际运用中体会和感悟语言形式的表意功能。课标分解能通过阅读，简单介绍文本相关内容；能通过具体语境和练习，正确使用现在完成时；能通过小组讨论，简单介绍太空poster。教材分析本模块以“太空旅行”为话题，通过描述人类探索太空的历程强化对科普说明文的理解能力。Unit2的主要内容是介绍太空的基本知识和人类对探索太空付出的努力。学生以理解为主，最后一组问题设计地很巧妙，也正是学生想问的，也能够引起学生的积极思考。在本课中，利用现在完成时去表达人类探索太空已经发现的事物，属于新知和重点。这就需要教师创造情境，以活动为载体，将词汇和句型结合。学情分析学生们在第一课时中已经对一些太空知识有了基本了解，但是对一些新的语言点的使用比较陌生，现在完成时中对于already/just/yet的练习比较少。在第二课时中将通过阅读扩大学生知识面，通过知识点的讲解和练习增强语用功能。教学目标通过本课时教学，让学生能够：1.在语境中记忆并强化用本单元有关的词汇none,environment，solar,systemgroup,galaxy，universe,light，impossible,out，communicate；2.通过读中学，熟练掌握目标词汇和语法知识，并能灵活运用；3.通过比较一般现在时和现在完成时，熟练掌握现在完成时，并能复述文本主要内容；4.通过拓展训练，熟练阅读技能，拓展文本资料；5.通过介绍poster，感受太空探索取得的进步，树立不畏艰难、积极向上的信念。评价任务评价标准在读中完成P2-3复述（指向目标3）准确复述星体之间的关系学后完成用单词的适当形式填空。（指向目标1）能用单词的正确形式填空读后完成知识点学习及训练（指向目标2准确写出答案4.拓展阅读补充相关知识（指向目标4）能在规定时间内找到准确答案5.根据poster内容简单介绍自己知道的太空知识（指向目标4）较为准确、流畅地说出教学过程教学环节教学活动评价要点Step1WarmingupBrainstorm:太空词汇接龙：SolarsystemSpaceSpacetravel(设计意图：检查上节课作业，激活学生所学知识，调动学生积极性。)Speakouttherelationshipamongthem.Universegalaxystarplanetsolarsystem(设计意图：回顾上节所学，激活记忆，检查学生学习效果。注意表达方式。)尽可能多的说出与太空相关的词汇星体之间的大小关系基本能说对，注意句子表达方式Step2ReadingandlearningReadPara2-3Payattentiontotheexpressionoftherelationshipamongstars.goaroundbecalledasmallpartofoneofLanguagepointsNoneofthemhasanenvironmentlikethatoftheearth.noneof…表示（三个以上）一个也没有。做主语时，谓语动词可用单数或复数。我们班没有一个人去过南京。_________________________________________他们中没有一个人看过这部电影。____________________________________________——教室里有多少学生？——一个也没有。____________________________________________你们中没有人能做出这道题。(workout)___________________________________that代词，在这里指代environment。That在句子中一般代替前文出现的不可数名词或可数名词单数，可数名词复数用those代替。北京的天气比潍坊的天气要冷。_______________________________________中国的人口比美国的人口要多。__________________________________________中国生产的机器比日本的好。_______________________________________________ReadPara1、Para4-5Underlinesentencesaboutthethepresentperfecttense看图造句2020.7.23China1960sAmerica一般过去时__________________________________________________________________________________
