Lecture Notes on "How People Pass Information" in Kindergarten's Large Class Science

Teaching material analysis: In this increasingly information-based society, people use various ways to transmit information. It is the focus of this scientific activity to understand people's information transmission mode and feel the change of information transmission mode. In this activity, children find information by themselves before class, create situations, communicate and share with each other, understand how people transmit information through watching, talking and playing, and stimulate their desire for invention and creation by letting children imagine the future information transmission.

Basic analysis of children: Large-class children have been able to pay attention to the surrounding life phenomena, so they have a preliminary understanding of people's modern information transmission methods, but they are not familiar with the past transmission methods. Children in large classes have a strong thirst for knowledge, and they can take the initiative to consult materials with their parents, and they can also boldly share what they know and collect in class.

Activity goal: 1. Understand the different methods and development process of information transmission.

2. By consulting materials and talking to each other, we can understand how people transmit information.

3. Feel the convenience brought by information transmission to life.

Activity preparation: questionnaire and children's picture books.

Activity flow 1. Discussion and communication:

I know the way of information transmission. Second, the picture tells the story of people's information transmission, and briefly understands the development history of people's information transmission.

Third, imagine the way of information transmission in the future.

Teachers can start to create information transmission situations. For example, I was praised by my teacher in kindergarten today and got a little red flower. How can I tell your parents the good news? Tell your friends? Tell it to distant relatives

Transition: Just now, we have tried many ways to tell others the good news, which means we are delivering the news. Besides these methods of transmitting information, what other methods do you know? We can talk about teachers' language by combining questionnaires: China people are very smart, and long ago, people thought of many ways to convey information.

For example, ancient people mainly used flying pigeons, bonfires, fast horses, code words, sign language, letters, flags and other methods to transmit information.

Modern people have ways to transmit information through post, telegraph, telephone, television and computer network.

Teacher: Now we have so many ways to transmit information. Let's boldly imagine what kind of information transmission methods will appear in the future. How will you send a message when you grow up? (This link allows children to draw their own ideas about the future information transmission mode, and arrange their ideas in the theme wall or area. )

Children's presupposition behavior Children actively think and discuss the methods of information transmission according to the created situation. Children boldly use questionnaires to tell the pictures of children's picture books, feel the diversity and changes of information transmission methods, and use imagination to boldly imagine the future information transmission methods.

The design is intended to create a situation for children to discuss the information transmission mode in the situation, and talk about the information transmission mode they know in combination with the questionnaire. This link allows children to imagine the future and stimulate their desire for invention and creation through pictures.

Reflection and reconstruction: children still have some experience in how people convey information, such as making phone calls, sending letters and sending short messages. But they are still not familiar with the way people used to send information. Through the previous questionnaire, children and parents consulted a lot of information together and learned about the changes in information transmission methods. But I find that children's imagination is not rich enough. I should encourage them to think more in the future.
