Today, the topic of my class is: beautiful vegetable rainbow, comprehensive activities in middle class, which is one of the theme activities of "vegetable friends" in our class.

Let's talk about textbooks first.

1. Textbook Source: This activity comes from life. In this autumn season, vegetables can be seen everywhere, and it is very convenient for us to obtain materials. There are many kinds of vegetables with rich nutritional value. There are many ways to eat, such as stir-frying, soup making, cold salad and pickling. In a word, we can't live without vegetables. However, although children know a lot about vegetables, they don't know much about their types, uses and nutritional values. In our daily life, the phenomenon that children don't like to eat vegetables is also very serious. It is necessary to deepen children's understanding of vegetables, stimulate children's interest in vegetables and guide children to eat more vegetables. As the "Outline" said, "it not only meets the actual needs of kindergartens, but also benefits their long-term development; It is not only close to children's life, but also helps to expand children's experience and vision by choosing things and problems that children are interested in. " So this activity comes from life and can serve children's lives.

2. Goal-oriented: The goal of an activity is the starting point and final result of an educational activity, which plays a guiding role in activities and teachers' teaching. According to the age characteristics of the children in the middle class, I set the goals of cognition, ability and emotion:

A, children try to match different colors on the basis of perceiving different colors of vegetables.

B, master the skills of cutting vegetables into strips and pieces.

C. During the activity, experience the fun of doing it yourself and have a passion for vegetables.

According to the goal I set, I focused my activities on: sensing the different colors of vegetables and knowing the collocation of colors (learn to arrange according to different colors). Deepen activities through children's independent operation. The difficulty of the activity is: children operate independently, master the skill of cutting vegetables from strips into squares, and put vegetables into glass jars in layers according to the different colors of vegetables. Improve children's hands-on ability. In a word, our activities are interesting, comprehensive and active, so that education can be integrated into life. To this end, we have prepared the following activities:

A. Space preparation: 6 operation desks are rectangular, and 2 desks are arranged into 3 long tables.

B, material preparation: "Vegetable Rainbow" is ready; Cucumber, radish, carrot, cabbage, red pepper, green pepper and other vegetables are cut into strips; Small dish, plastic knife, disposable tablecloth, pepper, star anise, sorghum wine, white vinegar, salt and sugar are placed on three tables;

C, experience preparation: children have a certain experience of vegetables (eaten or seen), and all-round preparation provides the possibility for the successful development of the activity.

Second, teaching methods:

This activity, the theme provided by the teacher, must arouse children's interest, let children actively participate in the activity, but also tap the activity value of this activity, so we adopted appropriate methods to organize teaching and adopted the following methods:

1. Operation method: The so-called operation method refers to children's hands-on operation, in which children gain corresponding knowledge and experience through independent exploration and discovery. In this activity, I arranged two operations for the children. The first time is the operation after arousing children's interest, mainly to let children explore the color of vegetable rainbow and know the hierarchical collocation of colors. Let children get feelings by looking, touching and smelling. Pave the way for the following operations. The second operation activity is to let children make "vegetable rainbow" by themselves, and put the cut vegetables into glass bottles layer by layer to make kimchi, which is our ultimate goal.

2. Demonstration mode: The demonstration mode of this activity is that the teacher explains how to cut the sliced vegetables into pieces, and demonstrates how to put the cut vegetables into bottles in layers according to color, and how to put all kinds of ingredients except vegetables into bottles, so that children can have an intuitive understanding of the specific production process of "vegetable rainbow". Direct demonstration can make children have a strong interest and let them have a more thorough understanding and understanding of the production.

In addition, we also integrate activities through exchange and discussion, appreciation and encouragement, aesthetic edification and dialogue activities. Let children get the understanding and experience of the diversity of work and achieve the harmony and unity of science, artistry, health and pleasure.

Third, the methods of speaking and learning:

Taking children as the main body, creating conditions for children to participate in inquiry activities not only improves and exercises their abilities, but also sublimates their emotions.

The learning methods we adopted in this activity are:

1. Multi-channel participation method: The target name of the new "Outline" in the scientific field clearly points out: (children) "can use a variety of senses to start thinking and exploring problems; Express in an appropriate way and exchange the process and results of exploration. " Therefore, in the activity, we guide children to take a look, touch, taste, smell and other sensory participation, and unconsciously become interested in this activity.

2. Try it: In the second operation activity, we encourage children to try to make a "vegetable rainbow" with the materials prepared by the teacher according to the teacher's demonstration. In this process, children try to make their own through independent operation, observing peers or peer cooperation. Of course, children may not be able to do well at once. They will try their best to make their dishes rainbow look the best and taste the best through continuous trials!

At the same time, we also express our rich and varied knowledge through complementary learning among children and cooperation between teachers and children.

Fourth, talk about the teaching process:

The process of this activity is as follows:

Stimulate interest, explore for free-work for free-taste exchange-activity extension

(A) stimulate interest (taste delicious rainbow vegetables)

At the beginning of the activity, the teacher took out the "vegetable rainbow" made in advance, let the children taste it and let them guess what vegetables the teacher made. Stimulate children's interest in observing "vegetable rainbow"

(2) Free exploration (observing plant rainbows)

According to the characteristics of children's strong curiosity, I will arrange for children to observe freely in the second link. We prepared vegetable rainbows in large glass bottles for each group of children to observe. In this process, the teacher is the guide. In a relaxed atmosphere, children touch, stare and talk about what they see. In this process, children's knowledge and experience are scattered. In order to be able to process and sort out, after children explore freely, we will sort out the knowledge and experience gained by children through introduction and collective evaluation. In this process, we presuppose that children will gain the following knowledge and experience: there are all kinds of vegetables in the glass bottle, cut into small pieces, and the teacher puts them in the glass bottle layer by layer according to the different colors of the vegetables, which looks like a colorful rainbow. It also contains wine and vinegar, and some black things (some star anise, pepper, etc. ).

(3) Independent operation (making vegetable rainbow)

Specifically, our activities are mainly labor activities. Through everyone's free exploration and the teacher's demonstration, the children became curious and interested in the activities, so we made use of the advantages of hot iron to arrange the children to operate freely and made a "vegetable rainbow". Therefore, we ask children to make it as much as possible through their own operation and mutual communication. At this stage, our main requirement is that the children put the cut vegetables into glass bottles layer by layer according to their colors. Therefore, as long as children see that their "vegetable rainbow" is as beautiful as the teacher's, they will be very happy and have a successful experience.

(4) Taste communication

The "vegetable rainbow" just made can't be eaten immediately, so we have classes two days in advance to make some delicious "vegetable rainbows" so that children who have just made their own "vegetable rainbows" can try them! This not only increases children's joy, but also increases children's expectations for their own production. They will continue to be interested with the question "Can my' vegetable rainbow' be as delicious as the teacher's cooking?". .

(5) Activity extension

After the activity, we can't finish. Then there is the child's expectation of his own production results. They hope that their "vegetable rainbow" can be delicious and enjoyed by everyone. Then, we can let the children take their own works home and invite their parents to taste them. At that time, children can not only experience the joy of success, but also get the approval of their parents! We can also ask parents to cooperate and make a "vegetable rainbow" with our children at home to let them experience another kind of fun!
