Design intent:
"Shanghai Preschool Education Curriculum Guide" puts forward the curriculum organization characterized by activities, emphasizes the value of activities, pays attention to the process experience of activities, and takes changing children's learning methods as a breakthrough to optimize the teaching and learning methods. These activities are based on children's life experiences. Near graduation, the topic that children discuss most is small schoolbags. In the choice of schoolbags, they often pay attention to styles, famous brands, colors and functions. However, it ignores the width of the shoulder strap of the schoolbag and the protective effect of the small schoolbag on the body. Therefore, teaching activities-carrying a small schoolbag, starting from the self-protection of children's bodies, combined with scientific knowledge: the pressure is constant, the greater the stress area, the less the pressure, and paying attention to children's experience and inquiry process, which can convey scientific knowledge to children in an easy-to-understand way and effectively use it in life, further stimulating children's interest in observation and inquiry.
Activity objectives:
1. Feel the different experiences brought by schoolbags with different widths and narrow shoulder straps.
2. Actively explore and cooperate with peers to complete the task.
3. In the activities, guide children to observe and discover phenomena carefully, and study scientific phenomena with empirical evidence.
4. Cultivate children's observation ability and hands-on operation ability.
Highlights and difficulties of the activity:
1. key: feel the different experiences brought by schoolbags with different widths and narrow shoulder straps.
2. Difficulty: I found the secret that wide shoulder straps are easier to carry than narrow ones.
Activity preparation:
Materials: Several schoolbags and books with different shoulder straps. Small experiment: two sponges and a small chair.
Activity flow:
First, different schoolbags-find the differences and lead to the topic.
1. These are schoolbags for primary school students. Are they the same?
2. Talk about their differences.
3. Summary: Small schoolbag, with so many changes, you are sure to find your favorite small schoolbag.
Second, carry a small schoolbag-experience feelings and discover secrets.
1. Just now you found that the shoulder strap of the schoolbag is wide or narrow. If you put as many books in these two schoolbags and carry them on our shoulders, which one will be more comfortable and relaxed?
Please cooperate with both of you to finish a task together.
Tip: two people work together-put five books in their schoolbags respectively-two people take turns carrying small schoolbags and walk around slowly.
3. Children cooperate to explore and communicate with each other.
4. communicate and share? Tell me how you feel. Which schoolbag is more comfortable to carry?
What do you think might be the reason?
1. Let's look at a small experiment. Sponges took the place of our shoulders. What happens when a small schoolbag is carried on our shoulders? What did you find?
5. Summary: When the schoolbag with thin shoulder straps is pressed on our shoulders, it will make a deep impression, which will be very painful and uncomfortable when we carry it back, while the schoolbag with wide shoulder straps will not hurt our shoulders, and it will be very comfortable and relaxed when we carry it back. Through a small experiment, we know that a schoolbag with wide shoulder straps can protect our shoulders and make our backs more comfortable. Therefore, when we choose a small schoolbag in the future, we should try to choose a schoolbag with a wider shoulder strap.
Third, migration and utilization-try to use and expand life experience
1. This is a schoolbag with thin shoulder straps. Is there any good way to make it wider and make your shoulders more comfortable and relaxed?
2. Show your schoolbag with shoulder straps and add a small' wide shoulder strap' to make our backs more comfortable.
There are still some such good methods in our life. Let's take a look at them together. Please think about where it has widened. What's the use of widening?
Activity reflection:
Teaching activities are carried out one after another in a relaxed and orderly process, and children learn happily and easily. The design of teaching links serves the goal of teaching activities, and the effectiveness of the activities is reflected. Activities focus on children's experience and exploration; Pay attention to the demonstration of scientific experiments, so that children can be demonstrated in real-time and effective observation to achieve a kind of * * * knowledge; Pay attention to the combination of scientific truth and life, and pass on scientific knowledge to children in a simple and life-oriented way. The extension of activities will make children pay more attention to the things around their lives and find more such good methods. The combination of science and life is more meaningful to teaching.
Activity evaluation:
These activities are based on children's lives. In this process, we pay attention to children's exploration and experience, let children fully express their experiences and feelings, and convey scientific principles to children in a simple and life-oriented way, so that children can learn and gain experience in happiness.
