Suppress transmission line reflection
The following are some ways to suppress the transmission line reflection: ##1. Impedance-matching 1. ** Terminal Connection ** - At the end of the transmission line, connect a resistance that is consistent with the transmission line's characteristic resistance to the ground or power supply. This can eliminate the reflection at the load side before the signal energy is reflected back to the source side, thereby reducing noise, electromagnetic interference, and radio frequency interference. However, this method had its shortcomings. The terminal resistance would increase the direct current power consumption, so the power consumption was high. It was not suitable for battery-powered products, and in the logic high state, the driving ability of the device was high. 2. ** Source End Connection ** - That is, a series resistance is connected to the transmitting end of the chip, so that the sum of the series resistance and the internal resistance of the chip is consistent with the transmission line resistance as much as possible. This termination method is simple and consumes little power. It does not bring additional direct current load to the driver. Only one resistance is needed to suppress the secondary reflection from the drive end to the load end. It is often used in point-to-point networks. However, it would increase the RC time constant and slow down the signal rise time at the load side, so it was not suitable for high-frequency signal paths. ##2. Reduce the factors that cause impendence mismatching 1. ** Consider transmission line type ** - Different types of transmission lines had different characteristic parameters. For example, coax cable has better anti-interference ability, twisted pair is second, and ribbon cable and single-wire have poor anti-interference ability. For the transmission lines commonly used in computer and digital systems, single-wire (including connecting wires and printed wires), twisted pair, ribbon parallel cables, coax cables, and twisted pair shielded cables had different wave impendence. For example, the wave impendence of a single-wire was the highest, about hundreds of Ohms. The wave impendence of a twisted pair was generally between 100 Ohms and 200 Ohms. The shorter the twist, the lower the wave impendence. In practical applications, the appropriate type of transmission line should be selected according to the needs to reduce the interference caused by the transmission line itself. 2. ** Avoiding Discontinuity Points on the Transmission Line ** - Discontinuity points on the transmission line, such as through holes and stubs, would cause the resistance to be mismatched. When designing a transmission line, one should try to avoid the existence of these disconnected points. If it cannot be avoided, then measures should be taken to compensate for the impact of these disconnected points on the resistance. ##3. Other measures 1. ** Signal transmission line structure design ** - For example, a flat structure is adopted, and the height of each ground wire is greater than the height of each signal wire. In the working process of the signal transmission line, the electromagnetic interference between the signal wires on both sides is isolated by the ground wires, effectively shielding the electromagnetic interference generated by the signals transmitted by the signal wires in the signal transmission line, reducing the crosstalk generated between the signal wires, maintaining the stability and accuracy of the signals in the signal transmission process, and thus reducing the reflected wave interference. 2. ** Use suitable measurement tools to optimize transmission lines ** - For example, there are more than 10 sets of the Transmission Loss measurement network analyzer, which can be used from 20 to 67 gigs. It can meet the needs of various high-frequency cables. There is also an 8-port network analyzer that can fully meet and respond to the special measurement needs of customers. Through these tools, the performance of the transmission line could be tested, and then the transmission line could be optimized to reduce adverse effects such as reflections.

What is the reflection coefficient of the transmission line?
The calculation formula for the reflection coefficient of the transmission line traveling wave is: <P>=<frac>{reflected wave amplitude}{incident wave amplitude}=<frac>{transmission line characteristic impedance-load impedance'}{transmission line characteristic impedance'+ load impedance'}, which is <P>=<vert><frac>{Zb- Za}{Zb + Za}<vert>(absolute value), where <Zb> is the transmission line characteristic impedance', and <Za> is the load impedance'. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Signal transmission and reflection
Signal transmission refers to the transmission process of electricity, light, or other forms of waves carrying information in different media (such as air, cables, or optical fibers). It is the basis for information exchange. The signal reflection refers to the phenomenon that occurs when there is a point in the interconnected line where the resistance is not continuous (for example, the resistance in the circuit suddenly changes) during the signal transmission process. When the resistance in the circuit suddenly increased, the signal would produce positive transmission and an overshooting phenomenon would occur; when the resistance in the circuit suddenly decreased, the signal would produce negative reflection and an undershooting phenomenon would occur. Signal transmission was a normal process of information transmission, and signal reflection was a special situation caused by specific conditions in the transmission process. Reflection might affect the efficiency and quality of signal transmission, resulting in signal distortion and other problems. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Light scattering, transmission and reflection
1. ** Reflection of light ** - [Description: When light encounters an obstacle, if the energy of the obstacle exceeds the energy of the photon, the light will bounce back.] When a single photon or multiple photons interact with an object and bounce back, it can be seen as a reflection of light. - Law: Reflected light, incident light, and normal are on the same plane; reflected light and incident light are separated on both sides of the normal; the reflection angle is equal to the incident angle, and the light path is reversed. - Category: - Mirror reflection: When parallel rays hit a smooth surface, the reflected rays are also parallel. - Diffuse reflection: When parallel light rays hit an uneven surface, the reflected light rays shoot in all directions. - Directional reflection: Between diffuse reflection and mirror reflection, there is reflection in all directions and the reflection intensity is not uniform. - [Usage: It is widely used in various optical instruments and equipment, such as glasses, telescopes, and microscopes, to transmit and magnify images.] 2. ** Light scattering ** - <Description: When light passes through an inuniform medium, a part of the light will deviate from the original direction. It is the result of the interaction between light and matter. Due to the inregularity of the medium, the phase of the secondary wave is irregular, and the transmission of light produces different intensity distribution in various directions.> - Category: - From the perspective of whether the frequency of light changed, it was divided into elastic scattering and inelastic scattering. - According to the relationship between the scattering medium's electric field and the electric field under the effect of the photoelectron field, it can be divided into linear scattering (corresponding to elastic scattering) and non-linear scattering (corresponding to inelastic scattering). The elastic scattering includes Mie scattering and Rayleigh scattering, while the inelastic scattering includes Brillouin scattering, Compton scattering, and Raman scattering. - Different types of scattering are widely used in many disciplines, such as Rayleigh scattering for high molecular research, atmospheric pollution monitoring, etc., Raman-scattering for many disciplines, Brillouin scattering for distributed optical fiber sensing, etc. 3. ** The transmission of light ** - "Description: When light is incident on a transparent or translucent material, part of it is reflected, part of it is absorbed, and part of it can be transmitted. Transmission is the phenomenon of the incident light being refracted through the object. - [Material: The object being transmitted is transparent or translucent, such as glass, color filter, etc.] Most of the light will pass through the object, except for a small amount of light that is reflected. If the light is strong, it will produce a scattering effect after penetrating the object. Translucency will cause the light to scatter inside (sub-surface scattering), such as milk, coke, jade, skin, etc. - [Usage: During the rendering process, reflection, refraction, and transmission can be applied to the rendering according to the light and shadow phenomenon in nature. The rendering effect can be more realistic.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the Teaching of the Transmission of Love in the Sports Games in the Nurseries
The following is a reflection on the possible teaching of the kindergarten sports game "The Transmission of Love": ** 1. Achievement of teaching objectives ** 1. ** Awareness goal ** - In the sports game "The Transmission of Love," if a cognitive goal was set to let the child understand the rules of the game, it might be found that the child's understanding of the rules was different. Some children may quickly understand and follow the rules to participate in the game happily, while others may need more guidance and demonstration. For example, when passing a specific item (such as a ball, sandbag, or other items that represent love), some children might forget the rules about the order of passing and not dropping it halfway. 2. ** Skill Target ** - From a skill perspective, if the goal was to train the child's physical coordination, throwing or catching ability, etc. It might be found that in actual games, the level of skill development of young children is uneven. Some children were able to skillfully perform the passing movements and show good physical control, such as being able to accurately pass the item to the next child in the throwing and catching segment. However, there were also children who might have difficulties, such as poor control of strength, causing the item to deviate from the target, or falling easily when running and passing. This reflected that when the game was designed, it might not have taken into account the differences in the starting points of different children's skills and the lack of consideration of hierarchical teaching. 3. ** Emotional goal ** - In terms of emotions, he hoped that children could experience the transmission of love in teamwork through games, and experience the joy of mutual assistance and sharing. Most children may indeed show a positive attitude during the game, interacting with their friends with enthusiasm and enjoying the process of playing. However, it was also possible that some children were too focused on their own performance or too eager to pass the opportunity, and ignored the emotional content of the transmission of love in the team. This suggested that in the follow-up teaching, emotional guidance should be strengthened to let the children better understand the emotional meaning behind the game. ** 2. Teaching process ** 1. ** Game segment design ** - There might be a problem with the continuity of the game segment. For example, if the transition between the warm-up session and the official "Love Transmission" game session was unnatural, it might be difficult for the child to quickly enter the game state. If the game was too simple, the child might lose interest quickly; if it was too complicated, the child might feel confused and frustrated. For example, if there were complicated transmission routes or too many transmission rules, the child might make frequent mistakes during the game and affect the game experience. 2. ** Teacher's guidance role ** - The teacher's guidance in the game was crucial. If the teacher's guidance is not timely and clear enough, the child may be confused in the game. For example, when a child violates the rules during the transmission process, if the teacher does not correct it in time, it may cause other children to imitate it. At the same time, if the teacher's motivational language and positive feedback are insufficient, the enthusiasm of the child may be affected. For example, when a child successfully completed a difficult passing action, if the teacher did not give timely praise and encouragement, the child might feel that his efforts were not recognized. 3. ** Child participation ** - Judging from the participation of the children, it might be found that some children were more active in the game, while others were less involved. This might have something to do with whether the design of the game was in line with the interests of all children. For example, children with introverted personalities might need more encouragement and personal guidance to fully participate in the game. In addition, the rationality of the game grouping would also affect the participation of the children. If the children's ability, personality and other factors were not taken into account during the grouping, it might lead to poor cooperation within the group and some children would be sidelined. ** 3. Enhancement measures ** 1. ** Teaching goal adjustment ** - According to the actual performance of the children in the game, the teaching objectives will be adjusted. For example, if it was found that children generally had difficulty in the skill target, the skill requirements could be appropriately lowered. First, the child could master the basic transmission movements in a relaxed and happy atmosphere, and then gradually increase the difficulty. As for emotional goals, children could deepen their understanding of the emotional content of the transmission of love by adding storytelling and creating situations. 2. ** Game segment optimization ** - To improve the design of the game. To ensure that the transition between the warm-up segment and the game segment was natural and smooth, you could use warm-up activities related to the game theme, such as a Mini games of passing balloons. It would simplify the overly complicated rules of the game and make the game more interesting and easy to operate. For example, changing the complicated transmission route into a simple straight line or circular transmission, reducing the restrictions in the transmission process. 3. ** Teacher guidance and improvement ** - Teachers should improve their guidance ability. During the game, they would correct the child's wrong behavior in a more timely manner and adopt a positive guidance method. For example, when a child violated a rule, they would not simply stop it, but guide the child to discover the mistake by asking questions, such as "Will we affect other children's love?" At the same time, increase the motivational language and feedback to the child, and promptly confirm every small progress of the child, such as "You passed it quickly and accurately this time, you are really a little expert in passing love!" 4. ** Pay attention to individual differences ** - In the game design and guidance process, more attention was paid to the individual differences of children. For children with low participation, they could arrange for cheerful friends to play with them, or give them more attention and special tasks to increase their confidence and participation. When dividing the children into groups, factors such as children's ability, personality, and gender were taken into consideration to ensure that each child could find their own role in the game and actively participate in the game of passing love. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the teaching of vertical line
The following is a reflection on the teaching of the vertical line: ** 1. Teaching guidance based on the reality of life ** 1. ** Concept Introduction ** - Students can make their own learning tools, such as two wooden strips or hard paper strips to make a movable corner that can rotate. Put the learning tool on the table and rotate one of the wooden strips to make one corner a right angle. Then measure whether the other three corners are right angles. From this, the concept of two straight lines intersecting at a right angle is derived, including the concept of vertical line, foot drop, and other related concepts. This method of drawing out concepts from the students 'hands was more acceptable than simply teaching them concepts and laws. 2. ** Drawing a vertical line teaching ** - The teaching of vertical line drawing should follow the order from easy to difficult. First, learn to draw any point on the straight line to make its vertical line, then learn to draw a vertical line at a given point on the straight line, and finally learn to draw the vertical line at a point outside the straight line. When instructing students to draw the vertical line of a known straight line, use a right-angle side of the triangle to overlap with the known straight line, and then draw a straight line along the other right-angle side. Also, pay attention to the overlapping side first before the overlapping point when drawing the vertical line. It could also inspire students to think about whether they could use other tools (such as protractor) to draw vertical lines. - In the teaching process, by letting the students draw a straight line at will in the group, try to draw a vertical line at any point on the straight line (outside), and exchange ideas, the students could initially realize that it was more standard to draw a vertical line with a triangular ruler. ** 2. Cultivation of students 'knowledge mastery ** 1. ** Understanding and expression of the vertical concept ** - The concept of vertical was relatively easy to understand, but it was difficult for students to express it accurately in words. For example, when doing related exercises, to accurately say the answer, you need to organize your language, such as describing which two lines are vertical to each other. 2. ** Understanding the concept of distance ** - The knowledge of distance was difficult for students. In teaching, students were asked to observe the graph of the line segment connecting a point outside the straight line to the straight line, guess which line segment was the shortest, and guide the students to say that it was a vertical line segment. This helped to understand the concept of distance, that is, the length of the vertical line segment was the distance. Although this was a difficult teaching point, the students might be able to understand it better through practice. ** 3. Strengths and weaknesses in the teaching process ** 1. ** Strengths ** - The level of teaching was clear, and it could lay a good foundation for the next segment, allowing students to better understand and recognize knowledge. For example, in the "distance" teaching, through a reasonable teaching design, the students would be guided to observe and guess first, and then the students would be guided to come to a conclusion. This would help them break through the difficult points. 2. ** Not enough ** - There may be some differences between the presupposition and the actual situation in teaching. For example, it may be difficult for students to understand the concept of the length of the vertical line, but the actual students may understand it better through practice. This also suggests that teachers should flexibly adjust teaching strategies according to the actual teaching situation. ** 4. Feel the value of vertical lines in application ** 1. ** The connection between mathematics and life ** - In teaching, students could go back to their daily lives to find the application of vertical lines. This would allow students to understand the nature of vertical lines, feel the value of mathematics in life, and increase their interest in mathematics. For example, in practical applications, such as the shortest canal digging problem when guiding water from the river to the farmland during irrigation, it could lead to the axiom of the shortest vertical line segment, allowing students to experience the role of mathematical knowledge in solving practical problems. 2. ** Understanding and application of the two axioms ** - In the teaching, through different teaching activities, such as drawing and exploring, students were allowed to understand the vertical axiom (in the same plane, there is only one straight line that is vertical to a known straight line) and the vertical line axiom (among all the line segments connecting a point outside the straight line and the points on the straight line, the vertical line segment is the shortest). They could also use these two axioms to make simple reasoning or application, such as solving related geometric calculations and actual route planning. 3. ** Cultivate students 'comprehensive abilities ** - By letting the students draw, explore, conclude, and other mathematical activities, especially hands-on drawing of geometric figures, it could train the students 'drawing ability, cultivate the students' observation ability, hands-on operation ability, and mathematical ability. At the same time, they could experience the rigor, science, and beauty of mathematics. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is the current in the transmission line single-phase or three-phase?
Reflection on the 2011 Shanghai subway line 10 accident
The 2011 Shanghai subway line 10 rear-end collision incident reflected many problems. From a technical and operational perspective, signal failure was the direct cause of the accident. The loss of power at Xintiandi Station disrupted the normal command and dispatching system of train operation, resulting in errors in the subsequent manual dispatching, which eventually led to a train collision. This indicated that the subway system had extremely high requirements for the reliability and stability of key technical equipment such as signals. Any technical failure could trigger a chain reaction and threaten the lives of many passengers. From a management perspective, the accident exposed a loophole in dispatching management. After the signal failure, although the telephone block method was used, it was obvious that the train dispatching process could not accurately coordinate the operation status of each train, causing the No. 1005 train to collide with the No. 1016 train in front of it after the departure of the ticket. This reflected that in an emergency situation, the dispatching and commanding ability of the subway operation management department, the response plan for special situations, and the coordination and communication ability between various departments were insufficient. From the perspective of the safety system, the accident also indicated that the entire subway safety system needed to be further improved. This included the daily maintenance and inspection mechanism of the equipment to ensure the stability of key equipment such as the UPS to avoid major accidents caused by minor faults such as loose lines. At the same time, in terms of personnel training, whether it was the dispatcher or the station staff, they needed to strengthen the safety awareness and emergency response ability to improve the response ability of the entire subway operation system in the face of emergencies and ensure the safety of passengers. In addition, this accident also reminded the community to pay enough attention to the safety of public transport infrastructure. The subway operator should constantly review and improve its own operation management system, the supervision department should strengthen the supervision of subway operation safety, and the public should also strengthen their self-protection awareness and pay attention to subway safety issues, so as to jointly promote the improvement of subway safety operation level. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Teaching plan and reflection on relay transmission of sports games in large classes
The following is an example of a teaching plan for a sports game relay: ** 1. Design Intent ** With the interest of the children in the Olympic torch relay programs, combined with the kindergarten's sports activities, such as roller skating (if possible), through the form of small groups taking turns to carry out, create a vivid image of the relay for the children, so that the children can obtain physical and emotional experience in the theme of the sport. ** 2. Activity Target ** 1. Let the children learn the running and handover movements related to the relay and develop their running ability. 2. To stimulate children's interest in sports activities by guiding their interest in positive activities such as the Olympics. 3. Cultivate the child's awareness of rules and the ability to execute rules. ** 3. Event preparation ** 1. [Field: Divide the field into suitable relay areas according to the number of children. For example, mark the relay track and handover area with colored tape or sign tube.] 2. [Props: You can choose a number of items according to the theme, such as a small flag, a relay baton, or a self-made torch model (the number depends on the grouping).] 3. [Reward items: For example, a number of small sticker or small medals.] ** 4. Activity process ** 1. beginning portion - The children entered in a column with the music, and then divided into several groups (such as four columns corresponding to four groups). - The teacher led the children to do simple warm-up exercises, such as head exercise, shoulder exercise, chest expansion exercise, waist exercise, knee joint exercise, wrist and ankle joint exercise, etc. Each movement was done four times eight beats. 2. essential part - Explain and demonstrate the relay movements - The teacher first demonstrated the movements of the relay run, including the starting position (standing with both feet in front of each other, with both hands at the sides of the body or slightly bent in front of the body), the arm swing during the running process (bending the elbow and swinging back and forth naturally), and the pace (running in small steps). - The key demonstration was the handover action. For example, during the handover, the previous child had to steadily hand over the relay prop in his hand to the next child, and the next child had to take the initiative to reach out to receive it. - Children practice in groups - Each group would first carry out short-distance relay practice in their own area, focusing on practicing the handover movements. The teacher went around to correct the child's wrong movements, such as the wrong posture when starting, and the falling of props when handing over in a hurry. - Gradually increase the relay distance so that the child can adapt to the complete relay process. - relay race - The teams were organized to have a relay race. Before the start of the game, the rules were emphasized again, such as the handover must be completed in the handover area and the children of other groups must not be disturbed. - The teachers would act as judges and award the teams that successfully completed the relay with a small sticker or medal. 3. ending portion - The teacher led the child to perform relaxation activities, such as deep breathing relaxation, muscle stretching (arm stretching, leg stretching, etc.), and each action was maintained for 15 - 30 seconds. - The teacher gave a simple summary of the activity, encouraged the children to actively participate in sports activities, and reviewed everyone's performance in obeying the rules and teamwork during the relay. ** 5. Reflection on the event ** 1. Child participation - During the activity, most of the children showed high enthusiasm for the relay game and actively participated in the practice and competition. However, there were still some children who were introverted or had weak athletic ability, so they were not enthusiastic about participating. In future activities, more attention and encouragement could be given to these children, such as arranging children with stronger abilities to participate in the group. 2. Skill Mastery - The children's mastery of relay running and handover movements was uneven. Most children could complete it well after practice, but there were still some children who had problems during the handover process, such as being too nervous during the handover, causing the props to fall or the handover speed to be too slow. In the follow-up activities, they could add practice sessions specifically for hand-over movements, and adopt a gamified method, such as setting up the selection of the "best hand-over movement" to increase the enthusiasm of the children. 3. Rule Awareness Cultivation - Through this activity, the children's awareness of the rules had improved to a certain extent. During the competition, most of the children were able to follow the rules, but there were still some children who were outside the handover area or interfered with other groups. This meant that the rules needed to be explained in more detail and vividly, and during the activity, it was necessary to discover and correct the behavior of the children who violated the rules in time to strengthen the cultivation of rule awareness. 4. Activity adjustment suggestions - In terms of activity preparation, the relay distance and the weight of the relay props could be adjusted according to the actual situation of the child to make the activity more suitable for the child's physical ability. For example, if the child's overall athletic ability was strong, the relay distance could be increased appropriately; if the child's relay props were not well controlled, they could choose lighter and easier to grasp props. - In terms of organizational form, it was possible to increase the interaction between groups, such as cheering each other or carrying out relay challenges to further enhance the children's teamwork and social skills. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the teaching plan of the relay transmission of the sports game in the big class
The following are some of the main points of reflection on the teaching plan for the relay relay game in the big class: ** 1. Achievement of the goal ** 1. ** Cooperation and teamwork ** - In the relay game, through the form of group competition, children can enhance their cooperation ability to a certain extent. However, during the game, some children may be too focused on the results of the game and ignore the cooperation between their teammates. For example, during the relay, there might be a situation where they were eager to pass the ball to the next person without considering whether their teammates were ready. This indicated that although the teaching process emphasized team spirit, more guidance was needed to let the children truly understand the importance of cooperation for team victory. 2. ** Sports Awareness and Sports Skills ** - For older children, the relay game could train their throwing and catching skills. However, in the game, it may be found that the level of children's motor skills is uneven. Some children may be able to throw and catch the ball better because of their good physical coordination, while some children may encounter difficulties, such as poor control of the throwing force and direction. This required more individual guidance in the teaching process to ensure that every child could improve their physical awareness and motor skills. ** 2. Teaching process ** 1. ** Warm-up exercises ** - The purpose of the warm-up exercise was to prepare the child's body for the subsequent game. Simple warm-up exercises such as jumping, clapping, and stretching could basically achieve this goal, but the possible problem was that the warm-up exercises were not interesting enough. If a more interesting way of warming up could be used, such as combining stories or children's songs, it might attract the attention of young children and make them more actively participate in warm-up activities. 2. ** Division and Rules Explanation ** - In terms of grouping, it was a good idea to appoint a team leader for each group. It could cultivate the children's leadership skills. However, individual differences and social relationships between children may not be fully taken into account during the grouping process. For example, some introverted children might feel nervous because they were assigned to a group with children they were not familiar with, which would affect the game experience. In terms of explaining the rules, although the rules of the game were introduced to the children, there might be situations where the rules were not explained concisely enough, causing some children to violate the rules during the game. 3. ** Guidance in the game ** - During the game, children should always be reminded to pay attention to cooperation and teamwork. However, sometimes this kind of reminder might be too frequent, affecting the child's autonomy in playing. At the same time, for some unexpected situations that occurred in the game, such as the ball falling, a slight collision between children, etc., they might not have prepared enough countermeasures in advance, resulting in temporary chaos in the game. 4. ** Game Reflection Section ** - During the reflection session, it was very beneficial to encourage children to talk about their experiences in the game. However, the possible problem was that some children could not express their thoughts well due to their limited ability to express themselves. This required teachers to cultivate children's language skills in their daily teaching, and to use more guiding questions in the game reflection session to help children better summarize their experiences and lessons in the game. ** 3. Child participation ** 1. ** Participating Rate ** - On the whole, the children's participation in the relay game was high, but there were still some children who might have low participation due to physical reasons or lack of interest in the game. Teachers needed to pay more attention to these children and understand the reasons why they did not actively participate. It was because they were not feeling well or because the difficulty of the game was too high or too low. Then, they would take corresponding measures, such as adjusting the difficulty of the game or giving more encouragement and support. 2. ** Independent operation space ** - Giving children a certain amount of independent operation space during the game, such as forming teams and choosing team members, can enhance children's ability to express and logical thinking. However, in the actual operation process, it may be found that due to the young age of the child, there will be some confusion when operating independently, such as disputes during the team formation process or the selection of team members is too casual. This required the teacher to give them the freedom to operate independently, but at the same time, they also needed to provide appropriate guidance and supervision. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
