这节课来自新目标 九年级 unit 6 Section A Grammar Focus 的内容，这节课以科技发明为话题，重点让学生在 熟悉的、与他们生活密切相关的语境中学习和运用过去时的被动语态即was/were+done的结构。教学中注重结合学生 的认知特点和语言学习规律，让学生在感知、体验、发现、自我探究、提炼总结中对语言结构进行学习和综合运用。 二、教学背景分析二、教学背景分析 学生学生 分析分析 通过平时课堂提问和检测，大部分学生已经有了一定的英语学习基础。但学生在情感态度,学习策略和文化 意识方面还存在诸多需要进一步解决的问题。例如：个别学生不明确学习英语的目的；有些同学对学好英语缺 乏自信，不敢用英语表达；缺乏小组合作意识；一些学生没养成良好的学习习惯，不能做好课前预习课后复习， 学习没有计划性和策略性；不善于发现和总结语言规律，不注意知识的巩固和积累。所以要求学生能课前认真 做好预习,借助网络和书籍,培养自学能力；教师在预设的任务中,注意引导学生在交际中动态生成,学生有话可 说,乐于合作分享。这样就有利于他们更好的运用课本知识,达到提高综合运用语言能力的目的。 教材教材 及本及本 课重课重 难点难点 分析分析 1、 教学重点：能正确使用was/were+done的结构描述各类发明的时间、人物、地点和起因等。 2、 教学难点：能用was/were+done的结构描述校园身边小发明的的时间、人物、地点和起因等。 三、教学目标与策略分析三、教学目标与策略分析 教学教学 目标目标 （一）知识与能力目标 在本节课结束时，学生能够 1、 学会正确使用was/were+done描述各类发明的时间、人物、地点和起因等； 2、 能用使用过was/were+done的结构描述校园身边小发明的的时间、人物、地点和起因等。 （二）情感目标 1、 能认识和了解科技技术给人类带来的改变和影响； 2、 激发学生创新意识。 教学教学 策略策略 随着初中学生抽象思维能力的发展，他们已经具备了一定的自觉接收、储存、加工信息的能力。语法教学 不应过于强调死记硬背，教师要结合学生的年龄特点和实际，设计科学、合理、有趣的课堂活动，鼓励学生积 极、主动地在活动中加深对语法规则的认识，概括和归纳语言使用现象，主动发现语法规则以及意义的表达， 逐步获得综合运用语言知识和语言技能进行交际的能力。 六、教学步骤六、教学步骤 步骤一：导入步骤一：导入 1、 教师通过播放视频，激发学生兴趣，引出语言教师通过播放视频，激发学生兴趣，引出语言 was/were+done 的结构的结构。 【设计意图设计意图】:以视频素材为依托，让学生在视频的文字篇章中,发现语言现象: was/were+done 的结构可 用于描述各类发明的时间、人物、地点和起因等。 步骤二：自我探究，发现规律步骤二：自我探究，发现规律 1、 让学生阅读与视频中让学生阅读与视频中有关发明的句子有关发明的句子，并观察句子形式，并观察句子形式结构结构。 2、 让学生总结划线句子的语言规律，进一步认识让学生总结划线句子的语言规律，进一步认识 was/were+done 的结构及表达用途。的结构及表达用途。 【设计意图设计意图】围绕教学知识目标，出示问题，利用教材、教辅自主学习、自主研究并总结 was/were+done的语言规律。 步骤三：运用语言步骤三：运用语言 教师通过教师通过有趣的摘苹果回答问题的游戏方式有趣的摘苹果回答问题的游戏方式，让学生运用目标语，让学生运用目标语 was/were+done 进行各种操练。进行各种操练。 【设计意图设计意图】通过设置不同难度的语言活动，让学生在不同情境中利用目标语 was/were+done 操练语言。 步骤四：合作展示步骤四：合作展示 1、观看、观看视频，发现学校身边的小小发明家和他的发明作品的时间、地点视频，发现学校身边的小小发明家和他的发明作品的时间、地点及及起因。起因。 2、学生、学生根据根据视频视频内容完成思维导图。内容完成思维导图。 2、教师、教师要求学生利用目标要求学生利用目标语言语言结构结构 was/were+done，以小组口头汇报的形式描述，以小组口头汇报的形式描述校园校园小发明小发明的发明人、的发明人、 发明时间、地点及起因发明时间、地点及起因。 【设计意图设计意图】以小组合作的方式，让学生利用目标语 was/were+done 来描述校园小发明的发明人、发明 时间、地点及起因，并以小组口头汇报的形式进行语言的输出。 步骤五：小结提升步骤五：小结提升 1、 教师在小组活动后，对本课时所学内容进行总结。教师在小组活动后，对本课时所学内容进行总结。 2、 情感教育：让学生情感教育：让学生在在各类各类发明发明和和至理名言中至理名言中认识认识和了解科技技术给人类带来的改变和影响和了解科技技术给人类带来的改变和影响，以激发以激发 学生的创新意识。学生的创新意识。 3、 布置作业。布置作业。 【设计意图设计意图】小结本节课的知识要点，并通过在各类发明及对名言品读，对学生进行情感教育的渗透， 激发学生的创新意识，好好学习知识和本领。 七、板书设计七、板书设计 Unit 11 When was it invented?
