Big class friends reflect after class
The following are some reflections on teaching in large classes: ** I. Children's reflection on time perception activities after class (refer to the social lesson plan of the first semester of the kindergarten class, One Minute)** 1. ** Event design ** - "Strengths: Through a variety of game forms, such as the" wooden man "game and the free-play building block game, let the children experience the length of one minute. The method is more intuitive and interesting. In the operation stage, different materials were provided for the child to operate within one minute, allowing the child to truly feel the difference in the results of doing different things in the same time. - [Weakness: The guidance for children in activities can be more in-depth.] For example, when children discussed why the results of doing the same thing at the same time were different, they could be further guided to think about how to improve efficiency, not just the reason for the speed of the action. 2. ** Child's performance ** - When children played as wooden figures, they could clearly feel the length of time, but when they played freely, they felt that time was short. This indicated that children's perception of time was closely related to their own activity state. In the operation segment, children could actively participate, but some children might have different familiarity with the operating materials, resulting in a large difference in results. For example, when picking up beads or marbles, children who had better hand movements and were familiar with the material completed more. 3. ** Teaching effectiveness ** - The goal of letting the child experience the length of one minute was achieved. The child could understand the value of time and the relationship between their own efforts. However, in order to cultivate the concept of cherishing time, some strengthening links could be added at the end of the activity, such as letting the child share his plans on how to cherish a minute in life. ** II. After-class reflection on the science activity "100% Fall"** 1. ** Event design ** - "Strengths: Use self-made teaching materials to arouse children's interest. Demonstrate, observe, experiment and other methods, in line with the children's scientific exploration learning method." Starting from the common phenomenon of objects falling, he gradually guided the children to understand the scientific concepts such as gravity. - [Deficiency: The preparation work is not perfect enough, causing the table and floor to be chaotic, affecting the order of the activity.] For some extended questions raised by young children, such as hot air balloon-related problems, they could be more prepared for possible problems before class, or set up special expansion sessions in class. 2. ** Child's performance ** - Children showed a strong interest in the phenomenon of falling objects. They could actively participate in discussions and raise many valuable questions, such as the reason why airplanes and birds could fly. This showed that children had a strong curiosity and desire to explore. However, during the experimental operation, some children might be too excited and not focused enough to observe the process of the object falling. 3. ** Teaching effectiveness ** - Basically, it had achieved the goal of letting the child have a preliminary understanding of the necessity and direction of the falling object. However, it could be further strengthened in guiding children to understand the concept of gravity. For example, more contrast experiments or animation could be used to deepen children's understanding. ** III. After-class reflection on the Big Bear Mountain story activity ** 1. ** Event design ** - [Strengths: By displaying the specially improved image of a mouse and asking key questions, it can effectively stimulate the child's thinking.] The activity focused on the interaction between the child's experience and the story, focusing on the child's independent thinking and expression. - Less: In the advancement of the story content, more interaction links can be added, such as letting the children discuss the psychological activities of the mice in different situations. The guidance for children's answers could be more diverse and avoid the single-minded guidance method. 2. ** Child's performance ** - The child's observation of the mouse was very detailed. When answering questions, he could describe it from multiple angles, which meant that the child had strong observation skills. When thinking about the changes of objects, some children could stick to their own views and give reasonable explanations, while some children could adjust their thoughts according to the new visual information, showing a positive state of mind. 3. ** Teaching effectiveness ** - It achieved good results in letting the children boldly express their guesses and imaginations about the story content. However, it still needed to be strengthened in guiding children to retell the story and perform role performances. For example, more demonstration and practice sessions could be added. ** IV. After-class reflection on the music activity of "I'm almost in Grade 1"** 1. ** Event design ** - [Strengths: Through the introduction of scenes, such as the rhythmic "Scholar", it can quickly bring children into the atmosphere of school.] By using the way of map interpretation, children could intuitively understand different singing forms, such as lead singing, follow-up singing, troll singing, etc., which had strong visibility and maneuverability. - Weakness: When guiding children to use harmonious voices to express songs, the methods can be more diverse. For example, in addition to verbal reminders, they could also use sound contrast to let the child feel the difference in the effects of different sounds more clearly. As for the exploration of singing after the children placed the pictures on their own, they could be given more time and guidance to let the children fully develop their creativity. 2. ** Child's performance ** - Children can actively participate in singing familiar songs, show a certain degree of observation and understanding ability in the interpretation of the map, and can try different singing methods according to the map. However, in the troll segment, some children might not have an accurate grasp of the rhythm and needed more practice. 3. ** Teaching effectiveness ** - It had achieved a certain effect in letting the children try different singing forms to express their happy mood in the first grade. However, there was still room for improvement in allowing children to understand the meaning of the song and better express their emotions through singing. For example, they could add some sharing sessions about the beautiful vision of the first grade in the activity to let the children better integrate with the song emotionally.

Middle class, social class, little red flower, looking for friends to teach and reflect on
The teaching reflection of Little Red Flower Looking for Friends is as follows: - In terms of teaching introduction, using the folded red flower before the child was a clever way to attract the child's attention. However, the shortcoming was that the story was not told completely, which made the teaching incomplete. - Teaching: - It was better to tell the story in sections and ask questions in the first part. It would help to sort out the content of the story and also allow the child to freely express his understanding of finding friends. It would be convenient for the teacher to understand the child's relevant experience. - In the second segment, watching the performance and appreciating the story in its entirety could further enhance the child's understanding of the completeness of the story. - In the third segment, the children were asked to talk about their good behavior and reward them with small red flowers. Combined with the reality of the children's lives, the correct behavior was strengthened. - In terms of teaching atmosphere, we should strive to create a happy, relaxed and lively classroom atmosphere, so that children can feel the teacher's love and care, and enhance their sense of belonging in the collective. - Children's attention: Pay attention to children who are not good at communicating with others in the class, give them more opportunities to communicate and express themselves, and guide them to play and learn with their peers. Children are encouraged to use polite language to greet others and create a relaxed atmosphere for them to express themselves boldly. At the same time, due to the individual differences of children, more attention should be paid to children who communicate less in teaching, improve their self-confidence, and encourage them to communicate more with others. In addition, children are young and their ability to consolidate knowledge is weak. Follow-up teaching should focus on consolidating knowledge. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Small class, music, games, friends, touch, reflect
The music game " Touch Touch " was suitable for the age of the children in the small class and had a positive teaching effect in many aspects. From the perspective of the children's participation, the children were very involved and particularly happy in the game from beginning to end. At the beginning, the child only remembered to find friends and forgot to sing. After the teacher's demonstration, the child could sing and play well and master the rules of the game. In the game, the children could sing and cooperate with their companions. They could touch their hands and feet with their companions in the music. They also hoped to find a teacher to touch them, which reflected the enthusiasm of the children for the game. In terms of achieving the teaching goal, the entire activity was run through with music games, and each link was connected naturally. The teacher used the form of singing and playing with the child, letting the child learn the song and movements unconsciously. Through playing, touching, and imitating dance with teachers and companions, children played games with ease and interest, experienced the rhythm of music and dance movements, and completed the purpose of music teaching. In terms of children's ability development, the game initially cultivated children's social communication skills, allowing children to experience the mutual contact and friendly feelings between friends. It also fully aroused the enthusiasm of children to "play" and "touch", and at the same time, it made them have a deep understanding of the names of various body parts. In the game interaction, the teacher was both the organizer and the participant, achieving an effective interaction between the teacher and the child. In addition, movements such as circle movements and changing friends could be used to guide children's learning in the form of games, satisfying children's desire for free performance and self-creation, and also improving their artistic aesthetic ability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Review the addition within 10 in the big class and reflect on it
The following is a reflection on the possible addition within 10: ** 1. Achievement of teaching objectives ** 1. ** Increase in calculation ability ** - In the process of reviewing the addition within 10, observe whether the child can calculate the result accurately and quickly. If most of the children were proficient in calculation, it meant that the teaching had achieved a good degree of improvement in the calculation ability. However, if some children still had difficulty in calculation, they might need to further analyze whether they did not understand the concept of numbers or did not master the calculation method. For example, some children might need a long time to think about simple addition such as 3 + 4 or make mistakes in their calculations, so they needed to consider strengthening the understanding of number combinations in subsequent teaching. 2. ** Engaging and Inducing Interested ** - To see if the child actively participated in the revision activities. If the child showed high enthusiasm in the activity, actively answered questions, participated in games, etc., this indicated that the teaching activity was more successful in stimulating the child's interest. On the other hand, if the child's participation was not high, it might be because the teaching method was not interesting enough. For example, the child would find it boring if it was just a simple calculation exercise. For example, if some teachers only kept writing formulas on the blackboard for the children to calculate during the review process, without the guidance of an interaction game or story, the children might soon lose interest. ** 2. Teaching methods ** 1. ** Diverse teaching methods ** - If a variety of teaching methods, such as game method, object manipulation method, etc., would it help children better review? For example, using physical objects such as small building blocks or fruit cards for addition demonstration, the child could intuitively see the process of adding numbers. For example, some teachers used apple cards in their lessons. They asked the children to count three apples, then take two apples, and then count the total number of apples together. This method was more effective than purely abstract numerical explanations. However, if only a single teaching method was used, such as asking the child to recite the addition formula, it might not be conducive to the child's deep understanding of the concept of addition. 2. ** The embodiment of teaching students according to their aptitude ** - During the revision process, attention should be paid to children with different learning abilities. For children with strong learning ability, were there any extended exercises or guidance to help them improve further? As for children with weaker learning abilities, did they give enough attention and individual guidance? For example, some children might be able to master addition within 10 through simple practice. At this time, they could be given some simple application questions to do, such as " Xiao Ming has three candies, and his mother gave him two more. How many candies does Xiao Ming have in total?" For children who were not sensitive to numbers, they might need to start from the basic number recognition, such as through number songs or number card games to strengthen their familiarity with numbers. ** 3. Teaching preparation ** 1. ** Rationally prepared teaching materials ** - Whether the teaching aid used in the class is helpful in reviewing addition within 10. For example, whether the prepared calculation cards were clear and clear, and whether the size of the numbers was suitable for children to see. If the teaching materials were not prepared sufficiently or were not suitable, it might affect the teaching effect. For example, if the color of the teaching aid was too dim or the numbers were not written properly, it might make it difficult for the child to recognize the numbers and calculations. 2. ** The connection between materials and reality ** - Whether the revision materials selected are actually related to the child's life. If he could relate it to the scenes in a child's life, such as the number of cutlery when eating, the number of family members, etc., it would make it easier for the child to understand the concept of addition. However, if the review material was separated from the reality of the child's life, the child might feel that addition was an abstract knowledge that had nothing to do with him, thus reducing his enthusiasm for learning. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
After class, reflect on the lack of passion in your class
The lack of passion in the classroom was a problem worthy of deep reflection. From the perspective of teaching effectiveness, a teacher's lack of passion would cause students to lack energy in the classroom, like a pool of stagnant water. For example, in the teaching case of Moonlight Song, the teacher lacked passion in the classroom and the teaching was stylized. The students already knew what to do before they entered the next step. This was very sad. From the perspective of affecting students 'interest and initiative in learning, it was difficult to stimulate students' interest in learning in a classroom that lacked passion. Students might have dull eyes, slow reactions, yawning, or even drowsiness, and they would not be interested in the content of the class. Under such circumstances, students might skimp on their homework, such as using three pens to copy at the same time to complete the task, or simply asking for help. Even if the teacher used punishment, such as copying the text, it would be difficult to change the students 'attitude. It might even cause the students to completely mess up and lose interest in learning. From the perspective of teachers 'own professionalism, the lack of passion in teaching methods may reflect the lack of educational wisdom. It was not enough to just work diligently. If one did not pay attention to the interests and feelings of the students and did not pay attention to the improvement of teaching methods, it would be easy to fall into the misunderstanding of exam-oriented education and utilitarian education. They would only pursue examination results and ignore the essence of education. To change this situation, teachers could start from many aspects. First of all, when designing the questions in the classroom, one had to consider whether they could stimulate the students 'interest and make them willing to participate in the answer. Secondly, the questions had to be clear and give the students a clear direction to think about. He also had to pay attention to the difficulty of the questions. If the questions were too difficult, he had to provide more clues to guide the students 'thinking. In addition, teachers should be good at mobilizing their own positive emotions and create a good classroom atmosphere so that students can tell everything they know and answer questions actively. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Big Class Mathematics Open Class Model Class
The following are some examples of a large mathematics public lecture: 1. ** Regarding the understanding of numbers ** - You can set up activities to let children find the numbers in their lives, stimulate their interest in numbers, and improve their ability to express the direction of numbers. For example, through conversation, the child could talk about the numbers he found yesterday and the function of these numbers. - In the teaching of the division and combination of numbers, such as the content of "the division of 10", the goal of the activity could be to explore the division and combination of 10, understand its different composition and decomposition relationship, further perceive the order of the division and combination of numbers, and cultivate scientific inquiry awareness. During the teaching process, the children could be guided to perform the operation of dividing and combining numbers through stories and other situations. For example, the children could help find the cow and then divide the cow, so as to learn the division and combination of 10, which could be expressed with simple formulas. At the same time, the children could feel the convenience and interest of the multi-media in the cooperation and communication. 2. ** Understanding RMB ** - In the public class with the theme of "Understanding RMB", the teacher could show the different face values of RMB and ask the children which face values they knew. From the perspective of food, clothing, housing and transportation, they could not do without RMB, so that the children could understand the importance of RMB in their lives. 3. ** Diagram and Space ** - In the three-dimensional figure recognition teaching, for example, to recognize the cube, cuboid, cylinder, sphere and other basic three-dimensional figures. The teaching goal included allowing students to recognize and differentiate these three-dimensional shapes and grasp their basic characteristics. Through observation, practice, and thinking, the students 'spatial imagination and logical thinking ability were cultivated. During the teaching process, physical models such as cubes, cuboids, cylinders, spheres, and other three-dimensional graphic models could be used to let the children learn the characteristics of various shapes through various links such as talking, dividing, recognizing, and playing. They could correct their vague understanding and connect them with life. 4. ** In terms of pattern exploration ** - In public classes such as Gem Forest, teachers could let children explore different arrangement rules through the forest game, such as the repetition, increment, and arrangement of objects from both sides to the middle, to stimulate children's interest in math games. - In terms of graphic combinations, teachers could create scenarios to allow children to spontaneously imagine the changes in the graphics, further consolidating the concept of statistics, bringing into play children's imagination and creativity, and making the game run through the entire activity process.

Small class rolls a ball into the cave to reflect
The following is a reflection on the small class rolling into the cave game (using the small ball to drill into the cave as an example): ** 1. Achievement of teaching objectives ** 1. ** Skill Target ** - In terms of children's skills of rolling and catching balls with both hands, if the child could skillfully complete the action of rolling and catching the ball at different distances, it meant that this goal was achieved. For example, in the free practice of rolling the ball, after many attempts and individual guidance from the teacher, most of the children could push the ball over and catch it with their hands before pushing it back. This was a success. However, if some children always deviate from the direction of the ball when rolling the ball (such as when the ball goes around obstacles such as caves), or if they can't catch the ball, it means that more practice is needed in this skill. - For the goal of letting children experience the joy of playing with their companions, if the children actively cooperated with their friends during the game, passed the ball to each other, and the game was full of laughter, then this goal was basically achieved. 2. Rule Awareness Target ** - For example, if a child could abide by a rule such as "one by one, don't push or squeeze"(the process of rolling the ball through the cave involves the rule of waiting in line), it showed that the rule awareness was effective. However, if there was a situation where many children ran into the cave without listening to the instructions at the beginning of the game (similar to the scene of rolling a ball into the cave) and caused the cave to collapse, it meant that the awareness of the rules still needed to be strengthened. ** 2. Teaching process ** 1. ** Event preparation ** - If the ball and the cave (chairs) could meet the needs of the children, the quantity was appropriate, and the quality was safe, then the preparation work was qualified. However, if there were too few balls, causing the children to wait too long, or if the cave was too simple or complicated, affecting the children's game experience, it would be a lack of preparation. 2. ** Teacher guidance ** - The teacher's guidance to individual children during the activity was crucial. If the teacher could find the problems of the children in rolling the ball, catching the ball, obeying the rules, etc. in time and give effective guidance, such as correcting the posture of the children rolling the ball, reminding the children to abide by the queuing rules, etc., this would be the highlight of the teaching process. On the other hand, if the teacher failed to pay attention to the needs of the child in time, or if the guidance was not clear enough, it would affect the teaching effect. - In the demonstration stage, the teacher's summary of the demonstration was very important. If the teacher could accurately point out the advantages and problems in the child's demonstration and emphasize the essentials of rolling the ball again, it would help the child to play the game better. 3. ** Game segment design ** - The game segment went from simple free practice of rolling the ball to a group game of small balls drilling into the cave, and finally to a free partner game. This kind of easy to difficult, step-by-step design was reasonable. However, if the transition was not smooth enough, for example, from free practice to group play, the child could not understand the new rules and requirements well and needed to improve. ** 3. Child's performance ** 1. ** Individual differences ** - Different children had different performances in the activity. Some children may be better at rolling, catching, and following the rules, while others may need more practice and guidance. Teachers needed to pay attention to this individual difference and provide targeted support in the subsequent teaching. 2. ** Emergency response ** - When there is an emergency, such as the child rolling the ball to other places in the game or fighting, observe how the child deals with it and the teacher's guidance measures. If the child could solve the problem peacefully under the guidance of the teacher, such as picking up the ball together or taking turns to play the ball, this was a manifestation of the child's good behavior and cooperative awareness. If there were bad behaviors such as crying or pushing each other, teachers needed to think about how to better guide children to deal with similar situations. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The Nature of Common Alkalines Students Reflect After Class
The following is an example of a student's reflection after class on the properties of common bases: ** 1. Knowledge Harvest ** 1. ** Physical properties of alkalites ** - In the process of learning the physical properties of alkalium, I realized some commonalities of alkalium. For example, soda is a white solid that is easily dissolved in water and releases a lot of heat when it is dissolved. These properties were well reflected in practical experimental operations and observations. For example, when I saw the phenomenon of the beaker wall heating up when the solid of the soda was dissolved in water, I was deeply impressed by its dissolving properties and the thermal effect when it was dissolved. This made me understand that physical properties are the basis for us to identify and distinguish different bases. In the future, if we encounter problems involving bases in chemistry or life, such as some chemical reactions that need to consider the dissolution of substances, this knowledge will be very useful. 2. ** Alkaline chemical properties ** - The reaction between the base and the indicator was an important chemical property. Through experiments, it was observed that the alkali-based solution could turn the purple litmus test solution blue and turn the colorless phenylethanes test solution red. This gave me a deeper understanding of the principle of action of the acid and base indicator, which is that the oh -ions in the base solution react with the indicator, causing the color to change. This property also provides a simple method for us to identify bases. - The reaction between the base and the acid was also the key chemical property of the base. For example, the reaction of sulfuric acid and sulfuric acid to produce sulfuric acid and water. This neutralizing reaction had many applications in real life, such as the treatment of gastric acid. I understood that the essence of the neutralizing reaction was the process of the combination of the hydrogen ion (H +) in the acid and the hydrogen ion (Oh -) in the base to form water. This not only deepened my understanding of chemical equations, but also allowed me to see the close connection between chemical knowledge and daily life. - The reaction of alkali-based compounds with certain non-metallic compounds was also the focus of his studies. For example, carbon dioxide reacted with soda to produce soda and water, and carbon dioxide reacted with calcium to produce calcium carbonite and water. These reactions were important in explaining some natural phenomena (such as the hardening of lime paste after painting a wall) and industrial production (such as the absorption of carbon dioxide with soda ash). In the process of understanding this property, I learned to analyze and explain the phenomena around me from a chemical perspective, improving my ability to use chemical knowledge to solve practical problems. ** 2. Inadequacies in the learning process ** 1. ** Experiment Operation ** - When I was conducting experiments on the properties of alkali-related substances, I realized that I was not proficient enough in some basic experimental operations. For example, when taking out the solid state of soda ash, it was very dangerous to not strictly follow the operating specifications and use tweezers to pick it up, but to touch it directly with the hands because of the strong corrosiveness of soda ash. This made me realize that in chemistry experiments, every step has its own strict rules and must be strictly followed to ensure the safety and accuracy of the experiment. - In the experiment of the reaction between the base solution and the indicator, I did not accurately control the amount of indicator added, resulting in the color change being less obvious, affecting the accurate judgment of the experimental results. This shows that I still have a lot of room for improvement in the refinement of my experimental operations. I need to pay more attention to details and improve the accuracy of my experimental operations. 2. ** Knowledge Comprehension ** - I still don't understand the reaction of alkali-salt. For example, the reaction between calcium dioxide and soda ash to produce calcium dioxide and soda ash, I still have some confusion in understanding the reaction conditions, the writing of the reaction equation, and the practical application of the reaction. This might be because I didn't have a firm grasp of the conditions for metathesis reactions (with precipitations, gas, or water). I needed to further review and consolidate my knowledge in this area. - When learning the corrosiveness of alkalium, although he had an intuitive understanding of it through the demonstration experiments in the classroom (such as the change of hair in hot soda, the change of chicken feet in concentrated soda), he was not clear about how to explain the corrosiveness of alkalium from the perspective of chemical structure. This meant that I still needed to strengthen my understanding of knowledge and the connections between knowledge. I couldn't just stop at the superficial understanding of the phenomenon. I needed to delve deeper into the underlying causes. ** 3. Modification measures ** 1. ** Experiment Operation Enhancement ** - In order to improve my experimental operation skills, I will watch more chemistry experiment operation videos after class, especially those related to alkali-related experiments, to learn the standard operation process. At the same time, I will actively participate in the chemistry experiment interest group or extra-cursory experiment activities organized by the school. I will do more practical exercises so that I can continuously improve my proficiency and accuracy in experimental operations. Before each experiment, I would carefully review the contents of the experiment, make clear the key points and precautions of each experimental step, and strictly follow the operating specifications during the experiment. After the experiment, I would carefully summarize the problems and lessons learned in the experiment. 2. ** Knowledge and understanding increased ** - In order to address my lack of knowledge, I will review the knowledge related to the metathesis reaction. I will do some exercises and analyze the actual chemical reaction equations to deepen my understanding of the reaction conditions. As for the corrosiveness of alkalites, I will consult relevant chemical materials or consult my teacher to understand the intrinsic reason for their corrosiveness from the chemical structure of alkalites (such as the nature of the radical ions). At the same time, I will build a knowledge network and connect the physical properties, chemical properties, and related chemical reactions of alkalites to form a complete knowledge system so that I can better understand and remember related knowledge. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
