Reflection after teaching（教学反思）
在本节课中，我设置了不同的任务，让学生在活动中通过合作和探究来完成各个任务。
这些任务有的容易，有的具有一定的难度，参与性强，参与面广，以便各个层次的学生都能参与到其中去。
不同的任务设置激发了学生的学习兴趣和用英语表达的欲望。
基本做到了把课堂让给学生，让学生在自主、合作、探究的气氛中愉快度过，既顺利完成教学任务，又促进其情感教育。
课堂教学具有趣味性。
因为涉及的话题是学生熟悉的风筝的制作和与物理有关的电的知识，而且设计了精美的、条理清晰、重点突出的POWERPOINT演示文稿, 用多媒体演示富兰克林风筝试验的动画。
“教有趣，必乐学”。
学习兴趣的形成有利于激发学生的学习动机，促进学生智能的发展。
本节课的教学内容设计符合了本班学生的实际情况，难度适中，尽量满足不同类型和不同层次学生的要求。
在任务的设置中充分考虑到了学生是否能够完成。

work in class.Teaching Aids:1.a slide projector and a computer for multimedia use2.a tape recorderTeaching Procedures:Step Ⅰ.GreetingsGreet the whole class as usual.Step Ⅱ.ResionT:In the last period we learnt some words,such as,charge,cross,tie….From these words,we learned that often a certain word can belong to more than one class and perform different functions,so it has more than one meaning in different sentences.Have you remembered these words?Let's review them.Please look at the words on the screen.(Show the words on theus the first example?S1:…T:(Teacher asks one student to make one sentence.Meanwhile,teacher types the sentences onStep Ⅲ.ReadingT:Nowadays science and technology is developing fast in many fields especially in medicine.Scientists keep developing new medicines to treat all kinds of diseases,which were hard to cure in the past.After a new medicine is developed,it must be tested on animals before we use it.Do you know this?Ss:No.T:This is very important.Almost every medicine we use has been tested on animals.Every year many animals die in experiments to develop and test new medicine.Do you think it's fair for humans to do this?Today we'll read a passage about animal experiment.Before reading,we first(Teacher asks students to read the new words several times and try to remember them.)T:Now open your books on Page 20 and read the passage quickly and answer the questions on the screen.T:Have you finished?Let's check the answers.Who can answer the first question?S3:Medical scientists say that animal experiments have been very important to find new medicines.Almost every medicine we use has been tested on animals.T:What about the second question?S4:Becasue they think animals and humans are not the same.What works with animals often does not work with humans.S5:Because they think animals have the same rights as human beings.There are laws to protect the animals.Humans have no right to kill them.T:Good.I think you understand the story very well now.Scientists and animal rights activists have different ideas about animal experiments.In the text,you should pay attention to these phrases:such as,test…on…,at least,There is no doubt that…,fight for.(Teacher writes them on the blackboard.)correctly.)Step Ⅳ.Listening and ReadingT:Now,I'll play the tape for you to listen.The first time I play it,just listen.The second time,you can follow and

passage which we just read is about different ideas whether we should test medicines and other products on animals.What's your opinion?Please write an essay to give your opinion about using animals in scientific experiments.Before writing it,please read the tips.According to the tips,make an outline for your essay in groups.(Teacher gives students enough time to read the tips and make an outline.Then check the outline and then write it on the blackboard.)Outline:Paragraph 1:Explain the reasons why animals are used in experiments.Paragraph 2:Explain why you are for or against the idea.Paragraph 3:Explain why some people who have different opinion from you are wrong.Paragraph 4:Give your conclusion.T:Now we have made an outline.Please work in groups to write an essay.Let's

try.Nowadays…(The student reads his/her essay to the rest of the class.)T:Very good.After class,you should copy the essay in your exercise book.Sample passage:Nowadays many animals are used in experiments to test new medicines and other products,such as shampoo,skin,creams and new cancer drugs.I think animal testing is very important to find new medicines.Animal testing has helped develop medicines against many diseases.If a medicine works with animals,there is a very high chance that it also works with people.But some people say what works with animals often does not work with humans and that humans have no right to use animals in experiments.Humans should take care of animals,but I think it is the best way to test new medicines by far and after all human life is more important than animal lions of animals are killed for ing animals for medical science is more important.Animals are human's friends.Without animals,humans can't live.But sometimes,we need them to do some experiments.I think we'll try to use fewer animals and take better care of them.Step Ⅵ.TestT:In this unit,we've learnt many useful phrases and sentence patterns.Now I'll give a test toSuggested

高一英语下册 Unit16 Scientists at work(第一课时)教案大纲人教版第一册Ⅰ.Teaching Goals:1.Think and talk about science and scientists.2.Learn how to give instructions.3.Study rules of word formation.4.Learn to write an argumentative essay.Ⅱ.Teaching Time:Four periodsⅢ.Background Information：1.Great Inventions伟大发明There have been many great inventions,things that changed the way we live.The first great invention was one that is still very important today—the wheel.This made it easier to carry heavy things and to travel long distances.For hundreds of years after that,there were few inventions that had as much effect as the wheel.Then in the early 1800's the world started to change.There was little unknown land in the world people did not have to explore much any more.They began to work instead to make life better.In the second half of the 19th century many great inventions were made.Among them were the camera,the electric light and the radio.These all became a big part of our life today.The first part of the 20th century saw more great inventions:the helicopter in 1909;moves with sound in 1926;the computer in 1928;and jet planes in 1930.This was also a time when a new material was first made.Nyloh came out in 1935.It changed the kind of clothes people had been wearing.The middle part of the 20th century brought new ways to help people get over diseases.They worked very well.They made people healthier and let them live longer lives.By the 1960's most people could expect to live at least 60.By this time most people had a very good life.Of course new inventions continued to be made.But man now had a desire to explore again.The world was known to man but the stars were not.Man began looking for ways to go into space.Russia made the first step.Then the United States took a step .Since then other countries,including China and Japan,have made their steps into space.In 1969 man took his biggest step away from the earth.Americans first walked on the moon.This is certainly just a beginning thought.New inventions will someday allow us to do things we have never dreamed of.2.The First Planes最早的飞机Steam engines were first to be tried in planes,but they were too heavy to be really useful.In 1884,such a machine was made,which consisted of a large number of wings one above the other and was driven by a steam engine.It is said that it rose for a moment off the ground.Another rose,but fell and was damaged.The real success of planes began only when petrol engine was used in planes.On December 17,1903,Orville Wright,an American,flew safely in a heavier-than-air machine for twelve seconds.He and his brother Wilbur had made a lot of experiments and had taken greattrouble to study the art of flying in gliders before they tried to fly their planes.Orville came down safely after the first short flight,and on the same day the experiment was repeated three times.The longest of these flights lasted 59 seconds.The speed of the plane was 35 miles an hour.The two brothers went on with their experiments after their first success,and in 1908 Wilbur gave some exhibitions of flying in France.All the people who saw the exhibitions were greatly surprised.Soon after the Wright brothers succeeded in their experiments,others followed in their footsteps.Louis Bleriot,a Frenchman,flew across the English Channel in 1909.Prizes were given for flights from place to petition began later.The plane improved more and more when people began to understand it better.In 1919 Sir John.Alcock and Sir Arthur Brown made the first flight across the Atlantic Ocean,and in the same year a plane flew from England to Australia.And then,the age of air travel arrived.The First PeriodTeaching Aims:1.Learn and master the following words:experiment gas flame wheel engine nuclear economy unnecessary comfort2.Do some listening.3.Do some speaking to talk about advantages and disadvantages of many science discoveries.Teaching Important Points:1.Improve the students' listening ability.2.Improve the students' speaking ability by discussion,talks and making some dialogues.Teaching Difficult Points:1.How to finish the task of speaking.2.How to make dialogues correctly.Teaching Methods:1.Warming up to arouse the students' interest in science experiments.2.Listening activity to help the students go through the listening material.3.Making simple dialogues to practise the students' speaking ability.4.Individual,pair work or group work to make every student work in class.Teaching Aids:1.a tape recorder2.a projector and a computer for multimedia useTeaching Procedures:Step Ⅰ. GreetingsGreet the whole class as usual.Step Ⅱ. Lead-inT:Now you learn several subjects at school,such as,maths,Chinese,English,physics,chemistry and so on.Which do you like best?Why?Any volunteers?S1:I like English.My wish is to go abroad some day,so I like English and I want to learn it well.S2:I like biology.I want to become a scientist to explore the secrets of life.S3:I like physics.I'm interested in electricity.I want to know more about it and make more use of it to make our life better and better.S4:…T:When I was your age,I often did experiments at school.(Teacher writes the word“experiment”on the blackboard.)Do you know the meaning of the word“experiment”?“Experiment”means“trial made in order to prove the truth of an idea”.For example,I hope to find the answer to this problem by experiment.(Write the example on the blackboard.)Do you often do experiments?S5:Yes.We often do experiments in physics,chemistry and biology in the labs or in the classroom.T:Do you do experiments by yourselves or do them with your teachers?S6:Most of the time,we make experiments by ourselves in the labs and we are directed by ourselves in the labs and we are directed by our teachers.In the classroom our teachers often show us some experiments.Step Ⅲ. Warming upT:OK.You have made many experiments.Can you describe some simple ones in English?Now,I'll show you three pictures on the screen.Please look at them carefully and then describe them.While doing this,the questions on the screen can help you.Please prepare this in pairs.(Teacher shows the questions and pictures on the screen.)Questions:1.Describe what you see in each picture.What is it about?2.What are the names of the school subjects in which you study science?3.Give an example of what you learn about for each field of science.No.1 No.2Picture 1Picture 2 Picture 3(Students begin to talk about the pictures and teacher goes among them and joins them.A few minutes later,teacher asks three students to describe them before class.)T:Are you ready?(Ss:Yes.)Who can give us a description of the first picture?S7:I'll try.This is an experiment in biology.From the picture,we can see two covers made of glass.The mouse dies after it's put into the first cover because of lack of oxygen while the mouse in the second cover is still living,because there is a plant in it.From this experiment,we know that green plants can produce oxygen.T:Very good.Now we'll go on to talk about the other two pictures.S8,the second picture.S8:…Sample writingIn picture 2,we can see an experiment of electrification by friction.In the experiment,the ruler after rubbed is put near the small pieces of paper.The pieces of paper are attracted onto the ruler.The experiment shows that electricity can be produced after two objects are rubbed.That's very easy and interesting.Picture 3 shows an experiment of the boiling of water in physics.In the picture,we can see the water in the test tube is turned into steam after heated.Then the steam meets the cold piece of glass and is turned into drops of water again.The experiment suggests that the form of water can be changed,but it can't turn into other things.Step Ⅳ. ListeningT:OK.When you are doing experiments,what should you pay attention to?Can you tell me your ideas?S9:We shouldn't enter the lab without a teacher.When we are there,listen to the teacher.S10:We should follow the teacher's instructions.Don't touch anything without the teacher's permission.Some of the instruments are dangerous.S11:…T:Very good.Next we'll do some listening practice.Let's see what Mrs Zhu talks about to the students.Now open your books to read the two exercises.In them,there are two new words:gas and flame.(Teacher writes them on the blackboard.)“Gas”means “substance like air and it can't be seen”；“flame”means“red or yellow burning gas and it can be seen.”Are you clear about the two words?S s:Yes.T:I'll give you three minutes to read the exercises to make sure you know what to do.(Three minutes later.)T:Now listen to the tape.For the first time,you just listen to get the general idea.When I play the tape for the second or third time,you'll try to finish your exercises.Are you clear?OK.Let's begin.Listen carefully.(Teacher plays the tape for the students to listen.When students are doing Ex.2,teacher should pause the tape for the students to write down their answers.At last,check the answers with the whole class.If necessary,play the tape once more.)Step Ⅴ. SpeakingT:Let's do some speaking.In this part,there are also a few new words.First let's learn them.Look at the screen.Teacher asks students to read the new words together,then gives them two minutes to remember the words.)T:There is a dialogue between two men in this part.They are talking about the advantages and disadvantages of a high-speed Maglev train from Shanghai to Pudong Airport.Now,please read the dialogue quickly and then find out its advantages and disadvantages.(After a while,teacher asks students to say the advantages and disadvantages.Meanwhile, teacher shows them on the screen.)them on the Bb.)in my opinion__________I think.In my opinion,he is clever.a waste of moneyDon't buy an expensive computer.I think it's a waste of money.make more/full/good use ofWe should make more use of every minute to study.(Teacher asks students to translate them into Chinese.)T:The work of scientists is often discussed.There are advantages and disadvantages to many science discoveries.Don't you think so?Now there are four inventions for us to discuss.While you are discussing them,the useful phrases on Page 18 can help you.(Students are divided into four groups.Each group talks about one invention.Teacher gives students enough time to prepare it and then asks them to give their ideas in front of the class.After that,teacher shows them on the screen.)Step Ⅵ.Summary and HomeworkT:Today we've talked about some pictures and known how to describe some simple experiments.We've also done some listening and speaking practice.Now we know how to discuss the advantages and disadvantages of some inventions.Meanwhile,we've learned some useful phrases.After class,remember the phrases and make a dialogue to talk about advantages and disadvantages of some inventions,using the information learnt today.Class is over.Sample dialogueA:Today I read a piece of news in the newspaper.It says that another cow has been cloned in our country.B:Really?The technique is very useful.It can save some rare species.Many animals will not die out.A:Are there any other advantages?B:Yes.It can be used to increase the number of some kind of animal in a shorter period if thistechnique is widely used.But it is impossible to do so at present in any country.It's said that some parts of human body can also be cloned.A:This is useful in medicine.But if humans can be cloned,that will be terrible.The whole society will be confused if it is not used properly.B:I am sure that scientists will agree on that in the future.Step Ⅶ.The Design of the Writing on the BlackboardStep Ⅷ.Record after Teaching____________________________________________________________________________________________________________________________________________________。
