Read the text correctly, fluently and emotionally, and know another big usage of quotation marks.

Learn to read the text silently and say the third paragraph of the text in an orderly way.

3. Grasp the key words and phrases to understand why Ampere uses the back wall of the carriage as a blackboard: That's because he is concentrating on doing math problems and understands that only by concentrating on his studies can he gain something.

Emphasis and difficulty in teaching

Key points: Through reading aloud, I learned that Ampere was very absorbed in scientific research and knew the function of double quotation marks.

Difficulties: correctly grasp? Mental arithmetic, calculation, calculus? .

teaching process

First, check the import.

1. Simple storytelling "concentrate"

Students, have we read the text? Blackboard? Run away, I believe that a few words here will not be difficult for you. (Provided by branches)

Scientific research by physicists

Concentrate on

Mental arithmetic calculus

(1) Read words by name.

Teacher: Who do you think of after reading these words? (Blackboard: Ampere)

Second, learn the first paragraph and refine the main line of the text.

The text introduces ampere in one sentence. Please find it and read it. (Read by name)

Show me the first paragraph of the text: more than 200 years ago, there was a famous physicist in France named Ampere, who was very absorbed in scientific research.

Do you understand? Famous? By changing the words (famous, famous, famous)

Can you also introduce ampere in your own words?

Show me the sentence: Ampere is.

(Purpose: to express the text completely and concretely)

Increase the difficulty: Ampere (how).

Ampere is very absorbed in scientific research.

(Objective: Refine on the basis of the previous link)

Camera blackboard writing: very hard

Do you want to know how Ampere devoted himself to scientific research? Then let's go to a busy street in France more than 200 years ago. Let the children read the second paragraph of the text and draw sentences describing the bustling streets.

Third, learn the second paragraph.

1. Show the second paragraph of the text. Free reading and communication

(1) What sentence are you looking for? Read it to everyone. The red line is drawn: pedestrians and vehicles come and go in the street, which is very lively.

Where do you see this street is very busy? (Catch the word: coming and going)

⑵ Video: 19 th century Europe's lively street scene. Finally, freeze it on a picture.

You see, one is used in the book? Come and go? What other words can you use to describe this clip? (Students say)

Xiu: The traffic is endless.

dǐng f？ Me, xi? cu？ n

There was a sea of people.

(read together)

(3) Instruct reading aloud: Can you express the excitement of the street by reading aloud? (Read by name, read together)

On such a busy street, where is Ampere? (Read related sentences by name)

(1) The blue line is drawn: but Ampere seems to have seen nothing, heard nothing, and just walked forward with his head down.

(2) Comparative sentence:

(1) But Ampere seems to have seen nothing, heard nothing, and just walked on with his head down.

(2) But Ampere saw nothing and heard nothing, and walked forward with his head down.

Are these two sentences the same? It's different. Where is it? (student exchange)

On the basis of students' communication, teachers and cameras guide:

Teacher: Flowers are in full bloom in the street garden, and many pedestrians stop to enjoy them. Ampere, have you seen them? But he turned a blind eye (blackboard writing: turning a blind eye)

Ampere, do you hear the noise in the street? But he didn't listen.

(2) Introduction: It turns out that he is thinking about a math problem.

[13] Summary: How careful Ampere is. No wonder the first paragraph of the text says that Ampere is very attentive to scientific research. Turn a blind eye to everything around, but turn a deaf ear. Ampere was so absorbed that he forgot that he was walking in the street! Let's read the second paragraph together and experience the concentration of amperes.

Fourth, learn the third paragraph.

Transition: Where else can you see that Ampere is very devoted to scientific research? Please read the third paragraph of the text. (Give students room to think)

2. Communication:

(1) In the process of students' communication, the camera pointed out three words with similar meanings:

Mental arithmetic, calculation, calculus

In the process of communication, I am very focused on scientific research closely related to ampere.

⑵ Thinking: Can the positions of mental arithmetic and calculus be changed?

After clicking? Mental arithmetic, calculus? Changed position. Students discuss.

(3) Good reading guidance? Great! ? If you are Ampere, just when you need the blackboard urgently, a big blackboard appears in front of you. what do you think?

Express your happiness, excitement and excitement. (reading? Great? )

3. The thinking process of Ampere is really interesting. Let's read together.

4. Retell: If you are Ampere, please tell me something about your thinking. If you can use three words on the blackboard and add your own actions, you can speak very orderly and vividly. (2? 3 students)

Comment on the students' narrative and return to the main line. Ampere is very attentive to scientific research.

Fifth, learn the fourth paragraph

Where do you see that Ampere is very devoted to scientific research? Students read freely.

Step 2 communicate

(1) points out? Count. Count? Thinking for a long time, Ampere has forgotten himself.

⑵ Draw what Ampere said, read by name, evaluate and model, and experience Ampere's concentration. Blackboard? You ran away and didn't wake up. Are you still facing the one who ran away? Blackboard? speak

(3) understand? Involuntary? ：

Teacher-student dialogue: blackboard? Go forward slowly, and Ampere will follow slowly; ? Blackboard? If you walk faster, you will follow faster; ? Blackboard? Run faster and faster. Ampere runs faster and faster. It's called. Involuntary? . (Students read words)

[13] How absorbed ampere calculus is! (blackboard writing: concentration)

4. Use illustrations and imagine speaking:

The beautiful young lady walking along the road whispered to her companions around her:

The gentleman in the top hat saw it and thought:

The passengers in the carriage found it and thought:

It turns out that Ampere is so absorbed in scientific research. Show amps and concentrate on scientific research.

Expand words: concentrate (write on the blackboard)

Sixth, learn the fifth paragraph.

1. Introduction: Later works? Blackboard? Ampere walked faster and faster, feeling that he couldn't catch up.

Interview with Ampere: Ampere, what's wrong with you?

Guide students to use sentence patterns when speaking: no buts

Point it out? Only?

3. Ampere's thinking is not general concentration. It's a blackboard writing: before concentration? Very?

Now, why can Ampere become a famous scientist in France? Use it? Because of this? Let's talk about sentence patterns.

Show the ammeter diagram and introduce the contribution of ampere.

Ampere makes a great contribution to electrodynamics. In memory of him, the unit of current intensity on the ammeter is named after ampere. )

5. Ampere is amazing. Let's boast an ampere first. Look at the first paragraph.

Summary: The mistake of treating the back wall of the carriage as a blackboard makes us clearly know Ampere's concentration in scientific research.

Seven, read the full text.

Eight, the teaching of new words: training, examination and beginning

1. Students learn independently and change their mastery? Pei? (companionship)

? Testing? : In Oracle Bone Inscriptions? Testing? Ask the students to imagine this picture: an old woman is on crutches.

? Start? Word combination: beginning and end, you know? Start? What is the antonym of? Eventually?

4. Instruct Tian Zige to write and give feedback on his writing (remind him of his writing posture).

Nine, extracurricular reading recommendation

There are many stories about scientists. You can read after class:

Rolling, a child who counts stars.

Edison, the child who hatched the chicken.

Einstein, a strange-thinking child

Boiling pocket watch Newton

? Strange guy? Fabre

blackboard-writing design

14、? Blackboard? run quickly

ampere

Very focused. Concentrate. Concentrate.

See but not see

Be deaf to ...
