First, the choice of teaching content:

The scientific activity "Understanding Clocks and Watches" in the big class is an activity this semester. The purpose of this activity is to guide children to know clocks and watches, the names and uses of the hour hand and the minute hand, so that children can understand the operation law of the hour hand and the minute hand and know the whole hour. Stimulate children's interest in observing things around them and exploring problems; Let children know how to cherish time and life through activities.

Second, the reflection on the teaching process:

Advantages:

Preparation stage: ① In order to let children participate in activities more actively, in the knowledge accumulation stage, I give full play to the positive role of parents, let children have a preliminary understanding of clocks in advance, and let children bring their own clocks to provide services for teaching. (2) In order to improve children's interest in learning, I adopt advanced teaching methods and courseware, so that children can grasp the teaching purpose more intuitively and actively while maintaining their interest.

Implementation stage: In the activity, I adopted several teaching methods, such as guessing discussion, exploring operation, discovery, games, speaking and learning. Reflecting on the whole activity process, I think the activity is basically successful. In the process of active inquiry, children's ability has been improved and their body and mind have been developed, which is mainly reflected in:

First, the presentation of knowledge is combined with the reality of children's lives.

It is pointed out in the Outline that the goal of science education is to be interested, curious and curious about things and phenomena around you. Can express and communicate the process and results of exploration in an appropriate way. ? Science teaching should be based on children's life experience and existing knowledge background, and provide them with opportunities to fully engage in scientific activities and exchanges. First of all, I use soothing music to form a relaxed atmosphere for activities. When knowing the clock, prepare enough materials for children to explain the versatility and universality of the clock in daily life, so that children can fully feel that the clock is around their lives. Knowing the clock is of great help to study and life, thus stimulating children's interest and motivation in learning and promoting children to actively explore new knowledge.

Second, provide children with opportunities to observe, think, discover and express.

Scientific knowledge, ideas and methods must be recognized, understood and developed by children in practical activities, rather than simply relying on teachers' explanations. In order to embody the new teaching concept, I consciously guide students to imagine freely and speak boldly. Through cooperation and communication, guide children to know the clock and let them consciously master the concept of time.

Third, the teaching and learning methods that reflect the interaction between teachers and students and the interaction between students.

In practice, children's hands-made clocks and watches and other practical activities not only stimulate their interest in exploring things, but also cultivate their observation and hands-on operation ability.

Insufficient:

The flow of this activity is designed according to the age characteristics and actual acceptance ability of large class children. In the activity, the children and teachers are truly integrated, and the activity effect is good. But there are still some shortcomings in the teaching process:

First, teachers are not skilled in using courseware, because they are novices in courseware teaching.

Second, teachers' teaching attitude is natural and generous, with affinity, but their ability to adapt to change, that is, educational tact, needs to be further strengthened in future teaching.

Third, the last link, let the children record the time, it is best to let the children dial first, and then pass the courseware verification.

Clocks are common daily necessities in our lives. It is necessary for the big class children who are about to enter primary school to know clocks, strengthen the concept of time and know how to cherish time. So I organized a math activity of "knowing the clock", and then I found that children were very interested in learning the clock. Looking back on the whole teaching process, my thoughts are as follows:

First of all, in the first link, use short stories to arouse children's interest and lead to topics. Figuratively speaking, the three hands in the clock are compared to big brother (hour hand). He is black and short, and people like to ask him what time it is. The second brother (minute hand) is dark-skinned, tall and skilled, and he can take his eldest brother for a short distance when walking around; Miss Qian Zhen is slim, thin and long, dressed in red, and likes to dance in circles. After listening to the story, many children guess that this is the clock that we often use in our lives. Then show a walking clock for children to observe and answer what the big brother, second brother and little sister in the story mean respectively. Finally, it is concluded that the elder brother is called the hour hand, the second brother is called the minute hand, and the younger sister is called the second hand. The key point is to let the children know the hour hand and the minute hand.

The second link is to understand the whole hour and answer the teacher in the form of nursery rhymes. It's x o'clock. In this session, I showed a stationary clock to guide children to observe and know 1 on the clock face first. 12 number, then dial the hour hand and minute hand to 12, and then dial the minute hand again, so that children can observe what happens to the hour hand (one step away) and guide them to tell what the hour hand points to. 1? It's one o'clock. Just dial it a few times until the two needles coincide. Let the children intuitively feel that if you want to know what time it is, look at the hour hand first. Then in the form of children's songs, teach children and teachers to ask and answer questions: after the teacher dials for a whole hour, ask: look, children, what time is it? The child replied: Teacher, teacher, look carefully. It's x o'clock. This link deepens children's understanding of the whole point through catchy children's songs.

The third link is playing with the clock. The above two links are all taught by teachers. The children are a little fidgety and eager to try. I immediately let the children play with needles freely, and everyone was very excited. Then I proposed? When, please? Password, with a clock demonstration. Through practical operation, children's understanding of the whole point has been consolidated, which is also the focus of this activity.

In the last link, add the hour hand and the minute hand, ask the children to finish the work of adding the hour hand and the minute hand in the homework book, and emphasize that the hour hand is drawn long and the minute hand is drawn short, which is good for the children.

What is the goal of science education followed by the whole activity in the outline? Interested in things and phenomena around you, curious, curious. Can express the process and results of communication and exploration in an appropriate way. ? When knowing the clock, prepare enough materials for children to let them feel that the clock is in their lives. Knowing the clock is of great help to their study and life. In practice, it not only stimulates children's interest in exploring things, but also cultivates children's observation and practical ability, which is a relatively successful activity.
