Unit1 Great Scientists说课内容

Senior Unit One Great Scientists

Good morning, ladies and gentlemen. My name is xxx. It’s my great honor to be here sharing my lesson with you.

I will begin this representation with five parts. Analysis of the teaching material, three dimensional teaching aims, teaching important and difficult points, the teaching methods and teaching aids, and the teaching procedure.

Part 1 Teaching Material

The content of my lesson is New Senior English for China Book Five, Unit One. This unit concentrates on Great scientists, including some scientists both at home and abroad like John Snow and Copernicus. The students will be encouraged to practise talking about these scientists. By studying of this unit, the students will learn about John Snow, who defeats “King Cholera” and learn how to organize a scientific research. We’ll activate the students’ knowledge about great scientists in the world and their achievements, stimulating the students' love and respect for them and the spirit of science.

The whole unit can be divided into seven parts: warming up, reading, listening and speaking, language focusing, reading and writing, grammar, and assessment.

In warming up, there is a quiz for the students to do, which will arouse the students’ interest in knowing about the famous scientists and help the students to know the significance of science in our daily life. Group discussion and brainstorming will be used in this period to help the students communicate with each other using their previous knowledge.

In the reading passage, the students will learn about John Snow, who defeats “King Cholera”, and get a general idea about how to prove a new scientific idea. This will help the students to form their own attitude towards science.

In learning about language, the students are encouraged to learn the following words and expressions: engine, characteristic, radium, theory, scientific, examine, conclude, analyze repeat, defeat, attend, expose, cure, control, absorb, severe, valuable, blame, immediately, handle, announce, instruct, virus, construction, contribute, positive, movement, backward, complete, enthusiastic, spin, reject, view, steam engine, put forward, draw a conclusion, in addition, link...to..., be strict with, lead to, make sense, point of view.

While practising using the language, the students will learn about Copernicus’ Revolutionary Theory, and their skills of reading, speaking and writing will be improved.

In listening and speaking, more chances will be given to the students to learn about other scientists and their spirit. The students are encouraged to make up their mind to make contributions to science.

The students will be asked to write a letter to Copernicus on the basis of the understanding of the text. The letters are sure to be full of imagination and creativity.

Assessment will help the students to look back what they have learned and focus on the difficult and important points.

Part 2 Three Dimensional Teaching Aims

Knowledge aims:

1. Learn something about some famous scientists in the world.

2. Know about the outstanding discoveries, inventions and theories from some well-known scientists.

3. Try to understand and master the usage of the important words and expressions.

Ability aims:

1. Talk about great scientists and their great achievements.

2. Develop the abilities of listening, speaking, reading, writing and finding relative information.

3. Guide students to set up effective studying strategies and train the students’ ability of cooperating.

4. Know how to prove a new idea in scientific research by abiding by the 7 stages.

Emotional Aims

1. Inspire the students to learn more about the great scientists and learn from them.

2. Help the students to form the good habit in learning and to take part in social practice.

3. Help the students realize that it is scientific spirit that makes those scientists successful and make them adapt the scientific spirit in their pursuit of knowledge.

4. Stimulate the students’ love for science and form their positive attitude towards science.

Part 3 Teaching Important Points

1. Make out the outline of the text.

2. Find out what John Snow did in the 7 stages, and find out the cause of cholera.

Teaching Difficulties

What can we learn from the scientists?

What should we do in our daily life to develop our interest and love for science?

Part 4 Teaching Methods

As senior students, our students have had a certain ability to read, listen and speak. They also have known something about scientists. However, since students’ English levels varies greatly, and they are poor in cooperative learning skills. Some students are not active in the class, others even don’t like English. Therefore, I’ll create relevant situations and have students study in a relaxed atmosphere. Students understand the new knowledge in certain degree through the mental process of watching, listening, speaking, thinking etc. For this reason, I’ll use following teaching methods:

Communicative approach

Audio－Visual approach

Task-based Approach

Teaching Aids

CAI equipment with a Multi-media classroom and other normal teaching tools.

Part 5 Teaching Procedure

Step 1 Greeting

T: Hello, everyone.

S: Hello, Miss Zhou

Step 2 Lead in

Encourage the students to share their dreams in the future and let the students brainstorm something about great scientists.

Purpose of my design:

(1) Stir the students’ enthusiasm in science.

(2) Arouse interest in expressing their feelings about their dreams and favorite scientist.

T: I’m very glad to see you all here. After a long holiday, all of you look energetic and happy. I hope that we will work hard together happily all through this year. I do believe that a bright future is waiting for you. By the way, I’d like to know what you would like to be in the future. Let me share your dreams.

S: I’d like to be an expert in environment. You see, with the development of industry, our globe is seriously polluted. Dirty water, polluted air, and loud noise make our living conditions worse. I think we should leave a beautiful world to the next generation.

T: Yes, someone predicted that the last drop of water in the world would be the tear of human being’s. I think all of us should pay attention to our environment, and make our contributions to improving the environment.

S: I’m so interested in physics. And I have read Stephen Hawking’s A Brief History of Time twice. I hope I will be a scientist like him. As we all know, the development of our society will go hand in hand with the development of science.

T: Yeah, I can’t agree with you more. Science plays an important part in the development of our society. There are so many examples in the history of human beings. I’m so glad to share your dreams. Your ambition and careful thoughts really leave a good and amazing impression on me. I like them. In this unit, you will learn something about “Great scientists”. Maybe you will know what you need in your efforts to realize your dreams after we talk about some world-famous scientists.

Step 3 Warming up

Have the students match the famous scientists with their discoveries, inventions or theories, making sure that they have some common sense about some world-famous scientists. Divide students into several groups and describe one of the great scientists, then let other students guess who he or she is talking about. In this way, the students will learn to organize their own sentences and express their ideas clearly.

Purpose of my design:

(1) Cultivate the students’ interest in scientists and science.

(2) Encourage Students to give more information about these scientists.

T: Now let’s match some of the great scientists with their famous discoveries, inventions or theories. Let me see who is the quickest in mind and action and can get all the answers correct.

Famous scientists Discoveries/Inventions/Theories

A.Isaac Newton 1.Evolution

B.Charles Darwin 2.Discovery of Radium

C.Madame Curie 3.Newton’s Law

D.Albert Einstein 4.Electric bulb

E.Thomas Alva Edison 5.Theory of Relativity

F.Nicolaus Copernicus 6.Seismograph

G.Stephen Hawking 7.A Brief History of Time

H.Zhang Heng 8.The earth moves around the sun.

(Check the answers with all the students: A—3, B—1, C—2, D—5, E—4, F—8, G—7, H—6.)

T: Since you have a better understanding of some of the great scientists, let’s play a game. Please work in groups and describe one of the great scientists, and then let other students guess who you are talking about.

Group 1: It is said that this English gentleman was sitting in his garden one day when suddenly he was hit by a falling apple. The story is probably not true, but this man did mention that he got one of his best-known ideas while watching apples falling from a tree. His name makes you think that he was not too interested in old things. He discovered the force of gravity, and he drew up a system of how objects move. His laws for motion are still used in physics today, at least in schools and universities.

S: Sir Issac Newton.

Group 2: Food is what sets this great mind on fire. Rice, to be exact. This great mind has spent most of his life looking for ways to help farmers grow more rice so that all of us will have enough food to eat. He is known as the father of modern rice, but because of his long friendship with all the farmers in China, he would rather be known as“the farmer”.

S: Yuan Longping.

T: Well done.

Quiz

T: You have already known some information about some of the great scientists.Now let’s do a quiz, trying to find out who these scientists are.

Brainstorming

Topic 1: What can you learn from these scientists?

Topic 2: What qualities should we have to be a successful man?

Attention: In this part, students may list many other adjectives which they have learned before to describe scientists. So teachers should be leading in these new expressions and make some connection between the old and the new, for example, bright can be equal to clever or wise, strict can be similar to serious, co-operative means work along well with others, enthusiastic means full of love for their jobs, and so on.

Step 4 Pre-reading

Ask the students to get ready for reading by discussing about some terrifying infectious diseases and the ways of making a scientific research. Encourage the students to express their different opinions.

Purpose of my design:

(1) Know something about the scientist John and his achievements.

(2) Have a better understanding about the significance of making a scientific research.

T: There are so many scientists that we can’t count them. But all the scientists must have their scientific attitude and scientific way to do scientific research. Now let’s have a dicussion.

T: First, let’s talk about infectious diseases. Can you name some?

Ss: Bird flu, SARS, cholera...

T: What do you know about cholera?

S: Cholera was a 19th century disease.

S: It was the most deadly disease of its day.

S: People who are infected with it will be easy to die.

T: Excellent. Now, let’s come to Question 2. How can we prove a new idea in scientific research? What order would you put them in?

Ss: find a problem—make up a question—think of a method—collect results—analyze the results—repeat if necessary—draw a conclusion.

Step 5 While-reading

Skimming: Read the material fast to find out the topic sentence for each paragraph.

Para 1 Brief introduction to John Snow and cholera.

Para 2 Two theories explaining the cause of cholera.

Para 3-5 The method of testing theories

Para 6 Conclusion

Scanning: Read the material carefully and take some important notes, then answer the following questions.

Purpose of my design:

(1) Train the reading skills and the ability of finding relative information by different reading skills.

(2) Arouse the students’ interest in English learning through proper competition.

T: Now, let’s read the passage carefully to learn about more details. Later I will let you answer some questions and fill in the chart. Let’s come to a group competition again.
