When was it invented说课稿7篇

When was it invented?第一课时 说课稿

一．教材分析

1．教材的地位和作用

本说课是九年级《go for it》第九单元“When was it invented?”本单元涉及内容是本书当中比较重要的一部分。被动语态结构及运用是教学中一个难点和重点，也是学生比较不容易理解的部分，因为它是建立在各种时态之上的。

另外通过对我们熟悉经常使用的发明物的历史来开阔眼界，丰富学生的阅历，使学生养成勤于思考，善于总结的好习惯。

2．教学目标

1）知识目标 扩容新单词，提高阅读能力。理解和良好运用被动语态。

2）技能目标 能谈论重要发明的历史及用途，能针对各项发明的用处及特点，发表自己的看法，并说明理由。

3）情感目标 使学生懂得人类的科学发明创造了丰富的物质文明。培养学生的创造发明的能力和愿望

3．教学重点 掌握一般过去时的被动语态

4．教学难点 弄清主动语态与被动语态的差异，通过练习和运用加以巩固

二．学情分析

1．初中生的抽象能力较低，形象思维能力强。但注意力容易分散。本单元通过多媒体课件和教师亲和力的语言，增强兴趣和注意力。

2．初中生的学习心理特点

1）兴趣对英语普遍感兴趣，求知欲盛。

2）记忆对刺激记忆手段多的知识记忆深刻，遵从记忆规律。

3）评价主要通过他人评价初步形成对自己的评价，所以很在乎他人的评价。同时自我意识不断增强。因此在本课教学过程中，注意采用任务型教学为主，通过任务和不同的评价方式，提高学生参与意识。

3．初三上学期学生有较明确的学习动机和态度。本单元通过发明为载体，各种发明和发明家激励学生求知的欲望。

三．教法渗透

1、教学设计思路与教材处理：

《新目标英语》中的具体语言目标是通过各种各样的Tasks来实现的；学生需要运用具体而特定的行动来完成一定的交际任务。整个教学过程中，各种语言结构与语言功能与不同的学习任务有机的结合。任务活动所谋求的效果不是一种机械的语言训练，而是侧重在执行任务中学生自我完成任务的能力和策略的培养；重视形式在完成任务过程中的参与和在交流活动中所获得的经验。因此本节课我将始终引导学生通过完成具体的任务活动来学习语言，让学生为了特定的学习目的去实施特定的语言行动，通过完成特定的交际任务来获得和积累相应的学习经验，让学生在用中学，在学中用。

2、教学原则

l 活动性原则提倡学生主动参与，体验，交流，合作，探究等多种学习。

l 合作性原则以学生为主体，师生合作，生生合作，体现教与学的互动，交往。

l 任务型原则任务驱动—激发动机；任务完成—激励学习积极性；执行任务—培养责任心和合作精神。

l 情感性原则激发学生学习英语的兴趣和始终保持良好的学习情绪。

3、教法运用：

本单元主要采用任务型教学

在本课的任务型语言教学中，我将依据课程的总体目标并结合教学内容，创造性地设计贴近学生生活实际的任务活动，吸引和组织他们积极参与，使学生通过观察、思考、讨论、交流和合作等方式，在一种自然、真实或模拟真实的情境中体会语言、掌握语言的应用。

4．教学手段

1）多媒体辅助：使用自制的课件，使抽象的语言变得直观，为学生运用英语进行交际创设情景，实现师生互动，生生互动和人机互动的多向交流。

2）非测试性评价：传统的评价观念的出发点是学科本位，只重学科，不重学生发展。要体现新课程标准的实施效果，评价体系应该“正确反映外语学习的本质和过程，满足学生发展的需要”。为了达到这一目标，唯有重视形成性评价，充分发挥其积极作用，促进新的评价体系的形成。因此，本课我将各种活动设计成小组活动并开展小组竞赛和填写课堂自我评价表等非测试性评价手段，帮助学生学会自主学习，学会与人合作，培养创新意识以及具备科学的价值观。

四、学法指导

新制定的《英语课程标准》把“培养学生学习英语的兴趣，树立自信心，培养良好学习习惯和形成有效策略，发展自主学习和合作精神”放在了首位。依据课改的精神，我从以下几个方面对学生进行学法指导。

1、学习方法的指导

培养学生观察力，想象力，记忆力以及思维能力。用生动的课件调动学生的感官进行听说读写的训练。

2、学习积极性的调动

我在教学过程中创造一种开放的，和谐的，积极互动的语言氛围，把课堂变成有声有色的舞台，让学生在乐中学。

3、学习能力的培养

通过连贯的听说读写，游戏，竞赛等，培养学生的交际能力，发展他们的思维能力。

4、学习策略的指导

本节课将在课堂活动中把学生分成四人小组的学习小组，让他们围绕着课堂任务分工合作，在活动中相互探讨、相互交流、相互合作，从而获得知识、技能和情感体验，发展他们的能力。创建开放式，探究式的课堂，有意识渗透学习策略的训练。我让学生观察课件画面，回答问题，让学生学会使用认知策略；让学生表演对话，实现交际策略；引导学生交际，主动练习和实践，是调控策略的体现。充分利用多媒体，录音，卡片等是资源策略。

五.教学效果预测；

1．能够掌握被动语态，并运用到一定的语言环境。

2．通过多媒体和任务的完成学生会突破难点，产生一定创造精神。

3．能完成教学目标，调动学生学习热情。

六．课堂教学过程：

Ⅵ．Teaching Procedures

Step Ⅰ Lead-in (2 minutes)

When was it invented? SectionA(1a—1c) 英文说课稿

Good morning, everyone. It’s my pleasure to interpret my lesson heretoday. The lesson I’m going to talk about is the first period of Book 9 Whenwas it invented? I’ll describe my thoughts on teaching this lesson in thefollowing 4 aspects: analysis of teaching material, ways of teaching andlearning, teaching procedures and blackboard notes.

First of all, I’d like to give some analysis of the material and thestudents. This material is from Book 9 When was it invented? The language goal of this unit is “Talk aboutthe history of the inventions”.

In this period, students will get in touch with the passive voice. It’sthe first time for the students to get in touch with the passive voice. Thisgrammar item is a key point also is a little bit difficult. In this period, Iwill mainly let the students touch with the passive voice. They realizeinitially what the passive voice is constructed and what it expresses. Thatwill be OK. I make "talk about the history of inventions" as thelanguage goal of the class.

OK, that is all about my analysis of material. And then I want to talksomething about the students. In our school, the students dont have much timeto learn some inventions. So I ask them to get ready for this lesson and try tofind information about the four greatest inventions of ancient China and someother famous inventors and their inventions. So they can have a concert of whatthey will learn in this class. I hope the students can hit the following goalsafter this class: they can realize the passive voice initially; they can usethe sentence structures learned to discuss the inventors and their inventions;they can realize the ancient civilization of China, strengthen the proud offeeling.

According to the learning material and the analysis of the students, alsoon the basis of NE C, I set the learning objectives as follows.

By the end of this session, most of the Ss will be able to achieve thefollowing aspects. First of all, most of the Ss will be able to learn and usesome important language points, like calculator, bulb, invent, inventor,invention and so on. Second, Ss will be able to use the following sentencepatterns to talk about inventions: When was the car invented? It was inventedin…Who was the car invented by? It was invented by.... Third, Ss will be ableto write an article about great invention.

These are my teaching and learning objectives. And the focuses lie onhelping Ss improve their ability to find out the information they need afterlistening, and the ability to write an article about a great invention, usingthe passive voice. The difficulty is the using of the passive voice.

Then let me say something about the teaching methods. In order to reach myobjectives, I’ll design some pair works and group works to increase Ss talkingtime on the basis of the student-based teaching method. And I’ll design sometasks to improve Ss’ listening and writing skills mentioned above, on the basisof task-based teaching method. Besides, in order to make the lesson lively andinteresting, I’ll try to use modern equipments.

Ok, so much for the learning strategies. Next comes to my most importantpart, the learning procedures. My Ss will learn the lesson in 7 steps.

Step one is warming-up. First, I’ll greet the Ss with daily conversations.And then I’ll show them some pictures of the ceremony (2008 Olympic Games ) onthe screen to talk about the Chinese history and the four great inventions.

Then I’ll show the pictures of the four great inventions, and askstudents: Who invented …? And then present the new sentence patterns: -Who wasthe paper making invented by ? -It was invented by Cai Lun. -When was itinvented ?- It was invented in Donghan Dynasty After that, ask students to ask and answer inpairs, using the above sentence patterns.

Then I’ll say that we have known some ancient inventions, ask Ss “ Do youknow any modern inventions?” Ask Ss to tell as many as they can, such as car,telephone, light bulb, computer and so on. And then ask Ss: “When were theyinvented? And who were they invented by?” So we will come to step 3. Ss mayfind out the answer after listening.

After the third step, I’ll show more inventions on Bb, and ask Ss todiscuss them in groups of four. Then give a report. Ss should use the followingsentence patterns while they are talking.

- When was the laser invented?- It was invented in

- Who was it invented by?- It was invented by

InventionsWhen was it invented?Who was it invented by?

airplane1903Light

E-mail 1971Tomlinson

telegraph1895Marconi

air-conditioner 1902Wailers

auto- dub machine1967Belon

ball pen1938Parishes

After the discussion part, we’ll go to step5-writing. Because after thelistening and discussion, it’s time for Ss to write something about aninvention. But first I’ll give Ss some oral examples about it. And examples cangive these students who are not good at English some help. And this oralpractice can make them easy to write the article. After the oral practice,we’ll come to write the article about a great invention. Before Ss write it,first I’ll help them how to begin the article. This can improve Ss’ learningstrategy. Before Ss write it by themselves, I’ll give them my examples, whichcan help those Ss whose English are not good to write. Next, the Ss will writethe article, and after they finish it, I’ll show them 2 articles from them toshare with them..

After the writing, it’s time to summarize what they have learned, andafter that, do some exercises, that will help to consolidate what they havelearned.

Exercises:

1.将下列主动句改成被动句：

1) Many people speak English.

2) We should look after our books well.

3) They make wood into desks.

4) They invited Tom to see a film.

2. They were invented ___ Julie Thompson.

A. as B. for C. by D. to

3. This watch _____ China

4. — ____ was the car invented?— In1983.

A. When B. Why C How D. Who

5. Basketball ____ by people allover the world.

A. is enjoyed B. is like C. love D. enjoyed

Finally, I’ll tell Ss the homework and say goodbye to them.

That’s all about my teaching procedures. Next I’ll say something about theBb design. As we know Bb note is the miniature of the whole lesson. It candisplay the procedures of the lesson and the language points learned in thislesson. It’s good for Ss to get the clear idea of the whole lesson. And teachercan use it to review.

That’s all about my lesson talk. Thanks for listening it. Bye!

When was it invented? Section A(1a—1c) 说课稿

各位评委老师：

大家好！我说课的内容是新目标英语九年级上册第九单元“When was it invented?’’的第1课时，即Section A(1a—1c)。下面我将从以下几个方面进行说课。

一．教材分析

这个单元围绕“发明”这个话题，让学生通过了解不同东西的发明历史和用途来学习语法项目——被动语态。再通过听、说、读、写训练熟练掌握语言知识和技能，最后让学生分析自己身边的发明的优缺点，从而进一步认识世界并改造世界。同时，教材内容从基本语言知识到语言综合知识的运用，层层递进，引导学生进行有目的学习语言。

二．教学目标

1.知识语言目标：能够让学生掌握重点词汇：invent,calculator,computer,car等。

让学生掌握一般现在时和一般过去时的被动语态以及其陈述句和疑问句。

2. 能力目标： 学会谈论发明的历史，认识些被发明的事物；能用被动语态进行对话。

3. 情感与价值：树立科学观念，培养积极探索，勇于创新的精神。

三．教法策略

以任务型教学策略为主，利用多媒体向学生展示发明物图片、听力训练法（处理听力材料）、并辅助个人、小组对话和图片等兴趣策略教学。如在新授单词时，通过一些图片，幻灯片等进行分析教学，以致于从视角引起他们注意从而记住单词。采取任务型教学策略的目的是主要是让学生多练多用，在做中学、学中乐、乐中掌握知识。

四．学习策略

通过角色表演，掌握如何利用被动语态谈论发明，在完成任务的活动中主动的学习语言，养成继续学习英语和学好英语的良好习惯。强调学生不仅要在课上积极发言、多练，并鼓励他们课后成立英语学习兴趣小组、英语角等，且鼓励学生积极参加。

五．重点、难点分析

重点词汇在对话和图片中解决。如：invent, calculator,computer,car等。

难点：听力训练；用被动语态谈论发明的历史和发明的用途来进行口语训练。

六．教学准备：黑板、图片、录音机、投影仪、一些发明实物。如：玩具汽车、电话机等。

七．教学过程

1、课前任务设置，在每一节课，我让学生提前预习。课前3分钟我让学生学唱“big ”big world ”的歌曲，目的是激发他们学习热情，另一方面铃声响的时候，首先检查学生对第八单元单词的记忆情况。然后让学生看着屏幕，用“When was carinvented?”等句子问，用It was invented in1885回答，之后通过图片展示推出其他的发明和新授的单元内容。在此期间，让学生感知“When was it invented? It was invented in…”的重点句型结构，把单词教学融入句型，培养学生在情境中理解记忆单词的能力。

2、为了更好的提高学生的理解能力，让学生有目的地完成Activity1a.请学生注意五幅图片，告诉学生这些发明是在过去150年发明的。通过投影仪展示图片，同时让学生说出发明的名称。老师在黑板上写下：computer,car,calculator,telephone,然后说出问题：When was thecomputer invented?再回答： The computer was invented in 1976.学生重复When was thecomputer invented? The computer was invented in 1976.接下来请学生看方框中的对话并复述。然后要求学生就五个发明物或自己的小发明进行小组对话。从而提高学生口语能力，帮助学生掌握被动语态。

3．完成1a部分后，为了更好的巩固学生对发明的理解程度，让他们通过1b进行听力训练，培养学生在用中学、学中用的能力。首先请一个学生说出1b 中五个发明名字，然后播放录音，同时让学生把发明物和发明的日期配对，最后检查答案。

4.为了更好的运用被动语态，请学生练习1c，然后请两个同学把对话说给同学们听.When was the telephone invented? I think it was invented in 1876.接着让学生用1a里的发明物或自己的小发明进行分组练习，最后请几组把他们的对话和全班同学一起来分享。

5、总结本节课所学的知识，梳理知识结构。

6、布置作业

总之，这堂课通过听、说、读、写训练，让学生熟练掌握用被动语态来谈论发明的历史和用途，利用二人小组活动，学生讨论各自对发明创造的想法以及他们自己的小发明，开阔学生的思路，让学生展开丰富的想象翅膀，培养学生的创新精神。
