3. Guide the children to discuss the usage of various bridges.
Teacher: We know there are all kinds of bridges. What do they have in common? Why are some bridges built on roads instead of rivers? Why are some bridges big and long, while others are small?
The children discuss and express their findings and understanding.
The teacher told the history of the bridge.
Teacher: Just now, we learned all kinds of bridges. Our ancient working people used their own ingenuity to design and build various bridges. With the development of science and technology, modern designers and workers have designed and built various modern bridges. What kind of bridge do you like? What kind of bridge do you think is good? Why?
Children observe children's books, broaden their horizons and enrich their experiences.
Activity reflection
Children are limited by life experience and know little about bridges, which affects their creativity. Make more preparations before class, so that children can observe and understand the shape and use of the bridge in their lives, enrich their experience, and let them better disperse their thinking and innovate.
A variety of teaching plans for large classes of bridges 3 I. Design intention:
A few days ago, we went for a spring outing, and the car drove over the viaduct. The children were very excited to say that they were on the bridge, so I asked what bridge it was. Some children say it's a viaduct. On the way, we also met many other bridges, especially the Taihu Bridge and the small wooden bridge in the park. I guided the children to observe these bridges along the way. Suzhou is a water city, and bridges are the most distinctive buildings in our city, so I suggest that children go back and collect all kinds of bridges to find out which ones are there. In view of these circumstances, we decided to introduce children's interest in bridges into our classroom and designated the following activities:
1, know all kinds of bridges and their relationship with people.
2. Understand the different shapes of the bridge, the different building materials used and the various functions of the bridge.
3. Be interested in all kinds of bridges and be able to actively participate in discussion and exploration.
The focus and difficulty of this activity is to understand the different appearance characteristics of the bridge, the different building materials used and the various functions of the bridge.
The preparation of the activity is to better achieve the activity goal, so all the preparations for the activity are selected around the activity goal: before the activity, build some bridges with the children by building games and visit the activity venue.
CD audio-visual products about various bridges, pictures and models collected by children about bridges, and photos taken during spring outing.
Second, teaching methods and learning methods.
For this activity, children have certain life experience, and as a supporter, author and guide in children's learning, I mainly use situational method to give children a situation, and then through the whole activity, I use the methods of communication, discussion, observation, inspiration and association to let children form their initial impression of the bridge in a relaxed and free environment. When solving the difficulties in activities, I first let my children observe the various shapes of the bridge, and then combined with my own life experience, I extended from the shape of the bridge to the building materials and functions of the bridge. In this process, from the superficial to the deep, from the surface to the inside, let children refine and form new experiences through methods such as perception, memory and association, and let children develop their abilities of observation, perception and generalization in swimming around the lake and opening activities.
Third, the teaching procedure.
I mainly designed three links for this activity. Visiting the model exhibition has aroused children's interest in bridges-guiding children to appreciate various bridges and know the building materials of bridges-and understanding the various functions of bridges, which has aroused children's interest in and thinking about bridges.
1. Visit the model exhibition of the bridge.
Children line up, just like a spring outing. The teacher beeped to show that he was driving and said to the children, shall we get on the bus and play together? Introducing a game scene can attract children's attention to activities. While driving, guide the children to look at the model and ask what bridge this is. There are Taihu Bridge, Viaduct and Jiuqu Bridge in the model. These models are brought by children and made with teachers, so they know what this bridge is and can fully stimulate the enthusiasm of children to speak.
2. Guide children to appreciate various bridges.
The children are sitting by the bridge. What do they look like? What is it made of? During the spring outing, the children made a good analogy to the Taihu Bridge. Now please tell them again, they will be very active. A good introduction to the following question: What other bridges have you seen? What is it like? What is it made of? Ask the children to talk about it. Teachers show pictures according to children's stories or on computers. The children have collected and observed the bridge, so they have some life experience and have something to say. At the same time, when describing what the bridge is made of, the child with strong ability is required to answer the teacher's questions together, but for the child with poor ability, he can't say these questions together, so remind him accordingly, such as what is he made of? Let the children say what the bridge looks like, but some bridges are very special, such as Huangpu Bridge. Some children may say it looks like a piano, others like a fan, and so on. We should praise and affirm children's bold imagination.
3, understand the main functions of the bridge, print and distribute children's observation interest and thinking about the bridge.
Our bridges have different shapes, some like what, some like what, and some like what. To sum up, some are made of wood, some are poured with cement, some are made of bamboo, and some are cut with steel wire. What are these bridges for? Arouse children to think about the role of the bridge. When children talk about the functions of bridges, most people may say that cars can drive, people can walk on bridges, and some bridges can pass trains. The children's answers are very general and there is no accurate classification, so I asked if all bridges can let cars and people walk together. Because of children's classification of bridges, because children have had the experience that only cars can walk on viaducts and only people can walk on footbridges, children will say no as soon as they ask questions. When children know that some bridges can only be crossed and some bridges can only be crossed by cars, they ask why some bridges can only be crossed by cars and some can only be crossed by people. By making children think and discuss, we know that concretizing the function of the bridge can improve our current traffic congestion. Finally, at the end of the activity, the teacher concluded: Our bridge has helped us to improve the traffic conditions and make it easier for us to get in touch with people from different places. Such a beautiful bridge has also beautified our environment. Do you want to design a beautiful bridge? Please tell each child what kind of bridge they want to design.
Four. Promotional activities
Let the children have an imaginary space for the bridge, and then lead the children to draw the bridge themselves. This link can be placed in the manual area of independent activities, and a game of bridge design institute can be specially opened. At the same time, it can also cooperate with the building blocks in the construction area, so that children can build their own bridges. Make children's interest in the bridge continue, further expand their imagination, and organically integrate scientific activities with artistic activities. These are just my thoughts, and I will carry them out and improve them in my future work.
The objectives of all kinds of teaching plan activities in the fourth bridge class:
1. Try to use different materials to build bridges with unique shapes and novel ideas.
2. Actively participate in activities and experience the fun of building bridges.
3. Cultivate children's spirit of trying.
4. You can learn to speak in turn and experience the fun of communicating and discussing with your peers.
Activity preparation:
1, all kinds of building materials and auxiliary materials needed for bridge construction.
2. photos of the bridge.
Activity flow:
1, watch the pictures of various bridges, and guide the children to discuss: how to use the learned construction skills to play games according to the different shapes of bridges.
2, children's group cooperation, using auxiliary materials to build bridges.
(1) Children can choose their partners freely.
(2) Group discussion: What kind of bridge are you going to build? What materials are needed?
3, children's games, teachers tour guidance.
Pay attention to guiding children to choose suitable materials according to the shapes of various bridges and make bold innovations to construct them.
4. Bridge exhibition.
(1) Ask the children to name the bridge they built.
(2) Who will be the little commentator and introduce your bridge?
Activity reflection
This kind of teaching activity can be carried out according to the teaching goal, using children's existing life experience and inspiring perception. Tell and operate to let children actively participate in activities, and gradually stimulate children's interest in hands-on activities and strong desire to explore. Invent innovative methods and experience the happiness brought by creation. Combining static and dynamic, paying attention to giving play to children's subjectivity, making children's thinking active and cultivating good learning interest and innovative quality.
Children are limited by life experience and know little about bridges, which affects their creativity. Make more preparations before class, so that children can observe and understand the shape and use of the bridge in their lives, enrich their experience, and let them better disperse their thinking and innovate.
The objectives of all kinds of teaching plan activities in Wuqiao Big Class:
1, understand the morphological structure and function of the bridge, and feel the convenience that the bridge brings to people's lives.
2. Let the children explore some simple bridge-building knowledge through two experiments.
3. Be interested in all kinds of bridges and be able to actively participate in discussion and exploration.
Activity preparation:
