teaching process
First, introduce the dialogue (2 minutes)
Teacher: When my teacher was young, I read in a book that astronauts landed on the moon by spaceship. At that time, I thought, it would be great if I could climb the sun one day! Do you think the teacher's wish can come true?
(Design intention: Guide students to talk about the reasons why we humans can't climb the sun according to the knowledge cards about the characteristics of the sun extracted and sorted out in the last class, and stimulate their interest in learning. )
Health:
Teacher: Yes! It seems that the students studied well before class, which is a good start for us to further study the lesson "Sun". Today, we will finish the learning task of the second lesson of The Sun together. (blackboard writing topic)
Second, learn the first part and know what methods are used to explain the characteristics of the sun (5 minutes)
(Design intention: read instead of say, let students realize that the text illustrates the characteristics of the sun by enumerating numbers, examples, comparisons and metaphors. )
(1) Teacher: Read the text by yourself, think about how the author specifically wrote the characteristics of the sun, find out the relevant sentences, and draw a picture with your favorite symbols.
1. Autonomous learning: read the text silently and sketch the relevant content.
2. Cooperative learning: two students at the same table can discuss. What method does the author use to explain the characteristics of the sun?
Show them on the big screen, read the sentences and tell me how these sentences are explained.
In fact, the sun is1.500 million kilometers away from us. (Description of column number)
(2) to the sun, if more than 20 years. (For example)
In fact, it is so big that1300,000 earths are worth a sun. (Column number, comparative description)
The sun will glow and heat, and it is a big fireball. (figurative explanation)
4. Guide students to read sentences and realize the benefits of explaining the characteristics of things by these methods.
It is very clear to explain the distance between the earth and the sun by numbers. If you don't use numbers, just say far, it will give people a vague impression.
Using familiar examples to illustrate it makes people feel very specific.
Compared with the distant sun, which looks like a plate, it is more impressive.
Use a big fireball as a metaphor to vividly illustrate the state of the sun.
Combined with the understanding of the sentence, the teacher drew on the blackboard:
Far, big and hot.
sun

For example, the relationship between the sun and oil can be expressed as follows:

Postscript of teaching:

Take off colored glasses
[case]
Two years ago, I took over as the head teacher of a new class in grade six. William Wang is an underachiever in the class. He belongs to that kind of irritable child, whose mood is very unstable and moody, and he often fights with his classmates for a little thing. None of his classmates dared to provoke him. Even if the teacher criticized him, he would avenge the prank. All his classmates hated his bad habits. Lin is the monitor, with good academic performance, a sense of justice and great prestige among his classmates.
One day after taking over for more than a month, I just rang the bell and went to the classroom as usual. As soon as I stepped into the corridor on the third floor, I heard a voice shouting: wipe it for me! I repeat, can you clean it? This is the voice of William Wang, with a strong smell of gunpowder, and a war is about to break out. I didn't have time to think about it before another voice rang again: I didn't step on it! This is Lin's voice. I immediately judged that this was a dispute with Lin. My first reaction was that William Wang was going to be domineering again.
I rushed into the classroom in three steps and two steps, and the quarrel stopped immediately. William Wang said: People saw him step on my stool, but he denied it! I asked Lin if this was true, but Lin firmly denied it. I trust Lin more, because he is always straightforward and has a good impression among teachers and classmates. It can't be Lin. It must be that William Wang didn't want to attend class, making trouble for no reason. I thought to myself. So, I explained it to Wang Han, found a rag to wipe his stool, and asked him to sit down in class. Although William Wang sat down, he didn't thank me. He just murmured: He is still an excellent teacher, so you can't judge right from wrong! I was shocked to hear that. I looked at William Wang, his eyes filled with deep resentment towards me.
I finished my class with anxiety. When I returned to the office, I felt terrible. William Wang's words were always buzzing in my ears. I decided to go to the classroom and get to know the situation with my classmates. Because the students hated William Wang, at first none of them wanted to tell the truth, saying that they had not seen it. I said seriously: Students, the teacher understands your's feelings. You don't like William Wang, so you don't want to tell the truth. I also hate William Wang's consistently poor performance. But please think about it. William Wang is also a member of our collective. If this matter is not handled properly today and William Wang cannot be persuaded, there will always be such a poor classmate in our class until graduation. Most importantly, we can't live without the basic principle of honesty! Hearing these words, the students were silent for a while. Finally, two students stood up and confirmed that Lin stepped on the stool.
I found Lin alone at once. I said to him: no one is perfect, everyone makes mistakes. The key is to have the courage to admit your mistakes. As long as you do this, you are still a good student in the teacher's mind and a good monitor of your classmates. Hearing this, Lin bowed his head and blushed and said, Teacher, I was wrong. I stepped on William Wang's stool. I must apologize to William Wang at the class meeting and deduct my conduct points twice. I must learn a lesson from this incident.
At the class meeting, I also apologized to my classmate William Wang, saying that I should not be biased and only believe what my good classmate said. I should investigate everything and not jump to conclusions. Every student is equal in the teacher's mind. My words greeted a burst of applause from my classmates. A satisfied smile appeared on William Wang's face. He felt that he and Lin were equal in the eyes of the teacher, and the teacher gave him back his dignity.
Since then, William Wang has gradually changed. She has gradually become less disgusted with teachers' criticism and education, more friendly to her classmates, and has begun to study hard. In the final conduct evaluation, the whole class agreed that he was good.
This incident inspired me a lot. Teachers, especially class teachers, must not look at students with colored glasses.
[analysis]
In ordinary schools, underachievers exist in any ordinary class, and the educational transformation of underachievers is a very hard, complicated and lasting work. As educators, how to treat students and underachievers well requires us to have correct educational methods and the ability to deal with accidental events. When there is a conflict between gifted students and underachievers, as a class teacher, we should calm down with a kind of love and peace of mind for students' justice, never look at students with colored glasses, never just listen to students' one-sided words, and fully investigate and study. The object of education we are facing is children who are in the growing stage both physically and psychologically. Adults make mistakes, let alone primary school students. Through the handling of this accident, I transformed an underachiever, found some shortcomings of gifted students in time and corrected them, and also established the prestige of the head teacher among the students.
