Mathematics, natural measurement, teaching plan, reflection, middle class, next semester
The following are some reflections on the mathematics natural measurement lesson plan from the first class to the second class: ** I. Reflection on the teaching plan of natural measurement in the big class ** 1. ** In terms of achieving goals ** - In the teaching plan of natural measurement in the upper class, the goal usually involved children learning the method of natural measurement, exploring the relationship between the length of the measuring tool and the measurement results, and developing interest in natural measurement. If the teaching plan is successfully implemented, the child should be able to master the correct measurement method, such as knowing to keep the measurement tools connected when measuring, and to start the second measurement at the end of the first measurement. However, in actual teaching, some children may find it difficult to understand the continuity of the starting point and the end point of measurement. For example, some children might randomly change the starting point of the measurement during the measurement process, resulting in inaccurate measurement results. - As for the exploration goal of the relationship between the length of the measuring tool and the measurement results, it may be difficult for children to discover the rules on their own. Teachers might need to use more guided questions and comparison operations, such as letting the child measure the same object with blocks of different lengths and then compare the measurement results to help the child understand this relationship. 2. ** Match teaching content with children's abilities ** - The content of the natural measurement should be challenging to meet the cognitive development level of the children in the first class. However, sometimes the choice of measurement materials in the lesson plan might be too complicated or simple. If you choose too complicated materials, such as objects with irregular shapes and difficult to operate, it will increase the difficulty of the operation of the children and affect their mastery of the measurement method. On the contrary, if the material was too simple, such as only providing a measuring tool with a simple shape and a short length, it might not stimulate the interest of the child to explore the measurement. - In terms of the infiltration of mathematical concepts, some simple mathematical symbols could be introduced to record the measurement results, such as numbers or simple marks. However, if the lesson plan did not gradually guide the child to understand the corresponding relationship between these symbols and the measurement results, the child might be confused about the recording process. 3. ** Teaching methods ** - In the teaching of natural surveying in large classes, teaching methods such as operation method and discussion method are usually used. The operation method could allow the child to learn measurement through personal experience, but the timing and method of the teacher's guidance during the operation process was crucial. If the intervention was too early, it might limit the child's independent exploration; if the intervention was too late, the child might spend too much time on the wrong operation method. For example, when a child's measuring tools are not neatly placed during the measurement process, the teacher needs to discover it in time and guide the child to correct it in an appropriate way, such as by asking," Do you think this measurement can accurately know the length of the object?" To inspire children to adjust themselves. - The discussion method was used to promote the collision of thoughts and the sharing of experiences between children. However, in actual teaching, some children might not actively participate in the discussion. This could be because the teacher's questions were not enlightening enough or did not give the child enough time to think. ** 2. Reflecting on the teaching plan of natural measurement in the second semester of the middle class ** 1. ** In terms of achieving goals ** - The cognitive ability of the children in the second semester of the middle class was weaker than that of the children in the first semester. The goal setting of the natural measurement teaching plan should focus more on the basic measurement experience. For example, the goal might be to let the child try to use natural objects to measure and get a preliminary sense of the meaning of the measurement. In actual teaching, some children might simply place the measuring tool next to the object without really understanding that measurement is a quantitative process of the length of the object. This indicated that teachers needed to pay more attention to guiding children to understand the nature of measurement in the process of goal implementation. - For children in the second semester of the middle class, the goal of exploring the relationship between measurement tools and measurement results should not be too high. However, in the implementation of the lesson plan, teachers may find it difficult for children to understand the phenomenon that different measuring tools measure the same object with different results. This might be because children were still in the stage of visual thinking, and it was difficult to understand the impact of the length difference of the measuring tool on the measurement results from an abstract point of view. 2. ** Match teaching content with children's abilities ** - The teaching content of natural measurement in the second semester of the middle class should be close to the life experience of children. If the object of measurement in the lesson plan was an object that the child was unfamiliar with, the child might lack interest in measuring. For example, it was not appropriate to choose some laboratory equipment as the measurement object, but choosing toys, tables and chairs around the children as the measurement object could stimulate their participation. - In the selection of measuring tools, natural objects that were simple and easy to operate should be selected, such as paper clips, straws, etc. However, in actual teaching, one might find that even these simple tools were difficult to operate for children in the second semester. For example, young children might have difficulty connecting paper clips to make measurements, which would require teachers to consider adding some guidance on the use of tools in the design of lesson plans. 3. ** Teaching methods ** - In the second semester of the middle class, the operation method and discussion method would also be used in the natural measurement teaching. The operation method was more important for the children in the middle class in the second semester because they mainly learned through hands-on operation. However, the teachers needed to be more meticulous in the organization of the operation. For example, the steps should be more clearly demonstrated before the child's operation, rather than simply showing the measuring tools. In the application of the discussion method, the teacher should pay attention to the difficulty of the question to suit the thinking level of the children in the middle class and the next semester. For example, the question should be more intuitive, such as " How many paper clips did you use to measure this toy?" It was not an overly abstract question about the relationship between the measurement tool and the result. Read more exciting novels for free

Who killed Luo Yining's mother?
The murderer who killed Luo Yining's mother, Gu Minglan, was Chen Lan. Chen Lan killed Gu Minglan with pufferfish poison. Although it seemed that Chen Lan was jealous of her husband's feelings for Gu Minglan, the real reason was not so. Chen Lan was a sensitive and thoughtful person. She had long noticed her husband's feelings for Gu Minglan, but she had endured it for many years and even gave birth to two boys and two girls with her husband. From the words she said when she persuaded her daughter to marry into the Princess's manor, it could be seen that her view on marriage was that interests were more important than feelings in the marriage of aristocratic families. Moreover, the men of aristocratic families would have to take concubines sooner or later. It did not make much difference to her whether the husband loved the concubine or the younger sister-in-law. Even if the husband loved Gu Minglan, it would make the backyard quiet. The real reason was related to a certain concept that Chen Lan had always upheld.
