First of all, talk about textbooks.
The selection of materials for this activity comes from life. Vegetables are a kind of food that children often come into contact with in their lives. They can be seen everywhere, and it is very convenient for us to obtain information. There are so many kinds of vegetables that almost every child can name several. Vegetables are also rich in nutritional value, and there are many ways to eat them, such as cooking, soup, cold salad and pickling. In a word, we can't live without vegetables. However, although children know a lot about vegetables, they know little about the edible parts of vegetables and the benefits of their nutrition to human health. Therefore, through a series of activities such as observation, discussion, speculation and production, children should know the characteristics of vegetables, deepen their understanding of vegetables, stimulate their interest in vegetables and guide them to eat more vegetables. Another example is that "the Outline" says "it not only meets the actual needs of children, but also benefits their long-term development; Being close to the child's life and choosing interesting things or questions will help to expand the child's experience and vision. " Therefore, this activity comes from children's lives and can serve children's lives.
Second, state the goal of the activity.
Activity goal is the starting point and destination of teaching activities and plays a guiding role in the activities. According to the age characteristics and actual situation of middle school students, establish the goals of cognition, ability and emotion;
(1) Understand the different edible parts of vegetables by understanding their appearance characteristics.
(2) Classify vegetables according to different edible parts (roots, stems and leaves, fruits) to cultivate children's classification ability.
(3) Know that vegetables are delicious and nutritious, and form a good habit of eating more vegetables and not being picky about food.
Activity focus: Vegetables can be classified according to different edible parts.
Difficulties in activities: improve children's classification ability, make clear that vegetables are delicious and nutritious, and educate children not to be picky eaters.
The main activity is to watch multimedia demonstrations to break through the difficulties in the process of children's independent participation, such as watching, speaking, guessing and scoring. To this end, I have prepared the following activities:
Third, talk about activity preparation.
The "Outline" points out that "provide rich and operable materials to provide conditions for every child to explore in various senses and ways." According to the outline, I made the following three preparations.
(1) School tools preparation: carrots, tomatoes, cabbages, potatoes and other physical objects. The number of vegetable pictures is equal to the number of children.
(2) Experience preparation: Children have some experience in vegetables.
(3) Preparation of teaching AIDS: multimedia courseware.
Fourth, talk about teaching methods and learning methods.
"Outline" points out that "teachers should be the supporters, collaborators and guides of children's learning activities", so the subjectivity of teacher-student interaction can be reflected in this activity, and the teaching methods adopted are as follows:
1. Scenario creation method: Using the animated image of "big head son" that children like, introducing children into activities is very suitable for the age characteristics of middle-class children and greatly arouses their desire for exploration.
2. Courseware demonstration method: By playing multimedia courseware, children can have a certain understanding of the growth process and composition of vegetables. In this process, the use of modern teaching AIDS has played an irreplaceable role in traditional educational means, making understanding and understanding more thorough.
3. Observation and guidance method: This teaching method is aimed at the situation of children in the process of activities, and teachers can adopt random guidance method, which reflects the ability of teachers to regulate and control activities.
4. Game method: Games are children's basic activities, which are educational, entertaining and creative. In the fourth part of this activity, I will guide children to find friends according to the pictures of vegetables in their hands, and add music to find friends, so that children can find them while singing and experience the joy of classification together.
I followed the children's learning rules and age characteristics in the whole activity, taking children as the main body. The learning methods adopted by children in this activity are:
1, multi-channel participation method: the goal of the new "Outline" in the scientific field clearly points out that (children) "can use a variety of senses to start thinking and exploring problems; Express and communicate the process and results of exploration in an appropriate way. " Therefore, in the activity, I guided the children to take a look, say, guess, divide and do, and unconsciously became interested in vegetables.
2. Try method: In the second operation, I encourage children to classify vegetables and guide them to classify according to the edible parts of vegetables.
3. Experience method: Psychology points out that "whenever people actively participate in experience activities, people's memory effect will be significantly improved". In order to make children have a deeper impression on the edible parts of vegetables, I adopted the way of game experience, and injected new vitality into the game activities with the relaxed and lively music "Finding Friends", guiding children to experience the joy of vegetable classification in singing and searching.
Five, said the activity process
In order to stimulate children's interest in activities, various teaching forms are combined around the goal, so that children are always in a state of active exploration. In order to complete the teaching objectives of this section, the activity flow is: stimulating interest-guessing game-operation classification-game experience-tasting exchange-making extension.
(A) set the scene to stimulate children's interest in inquiry. (Situation Creation) (Courseware Demonstration Method)
Interest is the best teacher. At the beginning of the activity, the teacher used the baby's favorite big head son and vegetable baby as guests, which aroused the children's interest.
1, Big Head's son came to visit with a group of baby plants. (PPT)
2. Children look at pictures of various vegetables. (PPT) Question: Do you know these baby dishes? What kind of vegetables do you like to eat? Do you know which part you are eating?
Let's take a look at what parts vegetables are made of. Show a complete picture of plant growth, and know that the plant is composed of six parts (roots, stems, leaves, flowers, fruits and seeds). (PPT)
Above, I created a situation for my children, which stimulated their interest in observing the characteristics of vegetables and provided them with opportunities for language expression.
(2) Guessing game: Show all kinds of precious vegetables one by one, and learn about the different edible parts of vegetables through guessing game. (PPT)
1, red paint bucket, buried underground, planted on the top of green leaves, cut the red paint bucket, cool and delicious. (Carrots) What do carrots look like? The teacher told the children that carrots are also called "talinum". Because carrots contain amylase, which can help digestion and benefit people's health, eating carrots can supplement vitamins.
Question: Which part of it are we eating? Can we still eat its roots?
2. solve riddles on the lanterns: It is red and round like an apple. It is sour, sweet and nutritious. It can be used both for cooking and as a fruit. (Tomatoes) Who can tell what tomatoes look like? (color, shape, skin, pit, taste, cooked or raw) So which part of the tomato should we eat? (Fruit) What other vegetables eat its fruit? (eggplant, pepper, pumpkin, wax gourd)
3. What vegetable is in the picture? (Cabbage) The teacher can talk about the appearance of cabbage. Which part of it should we eat? (Leaves) What other vegetables do we eat? Its leaves? (Spinach, vegetables, cabbage)
4. Q: What is this? Potatoes are also called potatoes or potatoes. Potatoes are poisonous when they germinate and cannot be eaten. If the bud is small, you can clean the bud and the surrounding meat before eating. We eat its stems.
5. Test the child: Son, which part of my screen do you usually eat?
(3) Understand the nutritional value of vegetables and educate children not to be picky about food.
Vegetables are nutritious and contain many vitamins. Eating more vegetables is helpful to our health and can make us grow taller, faster and smarter. So don't be picky about food at ordinary times.
(d) Game experience: the classified game "Finding Friends" (PPT pictures, background music)
Every child has a picture of vegetables in his hand, so that children can find friends according to the characteristics of vegetables. See which part your vegetable doll eats, and then listen to songs and sing to find friends.
Using light music, children can correctly classify vegetables in the process of finding friends and deepen their understanding of vegetables.
(5) Taste communication: vegetable salad.
The teacher showed a vegetable salad made of tomatoes, cucumbers and carrots, and let the children taste it, and exchanged the making methods of "vegetable salad". Let the children talk while eating, and gradually realize the truth that eating more vegetables is good in nutrition when they are excited, so as to consciously avoid picky eaters, let the body absorb more nutrition and let the body grow better.
(6) Extended activities:
Let the children go home and make vegetable salad with their parents to consolidate their understanding of vegetables.
