Unit7 How much are these socks (Period 1 Section A 1a-- 2d) 教学反思
Unit7 How much are these socks? (Period 1: Section A 1a-- 2d) 教学反思在这学期,我接了初一两个班的英语教学工作,使用人教版的英语教材,通过一段时间的教学,使我产生了一些困惑:首先是七年级的学生虽在小学学了一些英语,但他们学得不太好,整体基础很薄弱,而且各个学生能力程度不同,这就给我的教学造成了很大的困难及困惑,基础好的学生有的知识不用讲、练,或只他们稍微指点,就能理解与掌握;但基础差的学生没有兴趣,练了也不会,而且最大的一个问题是他们不愿学习英语,不写作业,一部分学生对英语都很头痛,上课,他们也不听,这让我很着急,不知道要用什么方法才能激发他们的学习兴趣,也不知道顾哪些学生好;但不管怎样,尽可能照顾到每一个学生,而今天这节课的效果有好的方面,当然也存在不足之处。
下面简单地回顾一下这节课开展的效果。
一、面向全体学生,为学生即将接受新知识奠定基础。
1、创设各种情景教学,使用多样化的教学方法进行教学,只要能激发学生的学习动机或学习兴趣;此外,还应鼓励学生大胆地使用英语,不管他们是否说得对与错,不要去特别在意,对他们在学习过程中的失误和错误采取宽容的态度,最主要的是他们愿意开口说。
而我发觉这些学生大部分都害羞,怕说错,在同学面前丢脸,从而导致他们对于学习英语失去兴趣,并产生恐惧感。
在教学过程中,每个需要掌握的知识点,我都让他们不停的练习,也反反复复拿出来讲解并及时联系。
虽说,我们的课堂教学活动是面向全体,对于后进生我们应多加关注,也应从差生入手,使他们掌握最基本的知识的同时,注意拓宽知识面;但也适当关注优生的学习情况,给予他们自主学习和直接交流的机会。
2、从学生的实际情况出发,为学生设计适合这堂课的教学方案,便于学生能够直观接受,更容易掌握。
因为这一课时的内容是谈论关于购买衣物,这些内容都是我们日常生活当中一些日常用语,与我们的生活息息相关,再则,使用多媒体教学来辅助教学,多多少少会少一些乏味,因此,我准备了实物辅助教学,大部分学生还是愿意听课,也配合教学活动的开展的;这堂课内容也为学生提供自主学习和直接交流的机会,以及充分表现和自我发展的一个空间。

Unit7 How much are these socks?
Section A说课稿
一、说教材(地位和作用)
本节课教材内容围绕着询问价格展开,内容比较贴近学生的日常生活,易于激发学生的
学习兴趣。
Section A在本单元中起着总领下文的关键作用。
在本节课中通过谈论衣物,让
学生在学会谈论物品及其颜色的同时,掌握用how much…句型来询问价格,学会感谢他人。
同时让学生能够利用简单的英语进行购物,为下节课谈论对服装的喜好做铺垫。
通过本节课
的教学,进一步培养学生运用英语的能力,使学生体会到学习英语的快乐。
二、说教学目标:
[知识与技能]
(1) 掌握表示服装的词汇:socks, sweater, trousers, jacket, skirt, dollar
(2)掌握如何询问物品价格的句型:①、How much is this T-shirt? ②、How much are these socks?
[过程与方法]
利用图片和多媒体课件来展开课堂问答式的口语交际活动及模拟现实呈现真实购物场景,通过由易到难、循序渐进的方法学习本课的新单词及其新句型,并且谈论服装、学习询问服装的价格与颜色;同时进行知识应用于实践的购物训练和听力训练。
以上这些将在“玩
中学,学中玩”的教学环境中具体体现。
[情感态度与价值观]
(1)树立正确的消费观念,养成节约用钱的生活习惯
(2)知道人民币与美元的差别,了解中西方的文化差异。
三、说教学重、难点
教学重点:
让学生学会谈论衣物,并在活动中运用单词:socks, sweater, trousers, jacket, skirt, dollar;句型:(1)、How much is this T-shirt? (2)、How much are these socks?
教学难点:
我把名词单复数的应用和如何在现实生活中询问东西的价格确定为本节课的难点。
为了突破难点,教学中利用了大量的图片、资料,给学生提供非常直观的感性认识.
突破措施:通过真实的情景激发学生的兴趣,反复练习加深印象,再循环记忆达到最终目标。
四、说学情分析
七年级学生精力旺盛,求知欲强,乐于表现自己,以前学过一些服装的名称和颜色,也学过1至10的数字,这些都为开展这节课创造了较好的条件。
五、说教法和学法
1、教法
英语新课程标准倡导任务型教学模式,即让学生在教师的指导下,通过感知、体验、实践、参与和合作等方式,实现该任务的目标,感受成功。
本课旨意在此。
因此本课多在课堂设计上下工夫,注意联系实际,模仿真实的英语语言运用环境。
让学生在小组合作中学会英语,掌握英语,运用英语。
本单元我采用的方法主要有:情景教学法、多媒体辅助教学法、合作学习法、小组竞赛法及循序渐进法。
通过多媒体、实物、动作以及图片等创设富有生活气息的语言情境,真正做到寓教于乐。
2、说学法
教师不仅是知识的传授者,更是教会学生学习方法、发展思维的引导者。
鉴于所学单词及句型特点及学生现有知识水平,我准备引导学生采用听、看、读、说的方法来学习本课。
通过听、看,达到有所思,有所得,帮助不同阶层的学生掌握学习重点;采用多表扬、勤鼓励的评价方法,使不同层次的学生都有学习积极性,提高课堂效率。
六、说教学环节
1.导入(Lea d-in)
Would you want to be handsome or beautiful? How do you to be handsome and beautiful? –To buy some beautiful clothes.为下面教授有关服装的新单词及价钱的问答作教学铺垫。
2.呈现(Presentation)
(1)通过出示bag ,hat ,T-shirt, shoes这些实物的图片,采用以下这些句型①What is ∕are this ∕these ? ②、What is the color? ③、Which one do you like?来复习这些已学过的单词。
(2)通过PPT展示 socks、shorts、sweater、trousers、jacket、skirt的图片,教授新单词。
(3)选用新单词中的一个单数名词sweater和一个复数名词socks学习新句型How much is this sweater? 和How much are these socks? 强调“is”,“are”的用法。
(4)游戏:通过PPT继续学习新单词shorts、trousers、jacket、skirt,并且让学生扮演顾客进行购物练习。
(5)小组活动:练习所学的新单词及新句型。
3、听力(Listening):1b
(1)让学生单纯的听听力。
(2)听并且作答。
(3)学生自行检查答案。
(4)检查答案。
训练了学生听的能力,巩固目标语言,加强了词汇和句型的理解和记忆。
4.总结(Summery)
(1)小结本课
(2)情感教育:节约钱财,合理消费。
5.板书设计(Blackboard Design)
Unit7 How much are these socks?
-----How much is this sweater?
-----It is eight dollars.
-----How much are these socks?
-----They are five dollars.
6.布置作业(Homework)
总之,通过本节课的学习,不仅使学生掌握购物的知识,更要达到英语是用来交际的最终目的。
同时使学生养成节约用钱的生活习惯,理解尊重父母,最终达到教育学生的教育目的。
