Line test assignment skill formulaThe following is the formula related to the line testing assignment technique:
1. There is no unit or only one type of unit in the data of the question. The valuation method can be considered to simplify the calculation.
2. If there are scores, the assigned value is a multiple of the Denominator, and multiple scores are the lowest common multiple of the Denominator.
3. The number of questions was proportional, and the value was assigned according to the proportional relationship.
4. For questions that satisfied the form A = B×C:
- If there are invariants, assign invariants first, and assign them as the common multiple of B or C; if A changes, assign B or C (there is a proportional relationship), and B or C will be assigned according to the proportion.
- There was no specific value, only a proportional relationship. It was assigned twice.
5. In engineering problems:
- Given time type: First assign the total amount of work as a common multiple of time, then find the efficiency, and finally find the required amount.
- Efficiency-constrained type: First assign efficiency according to the efficiency ratio, then calculate the total amount of work, and finally calculate the required amount.

Reflection on the teaching plan of sphere and cylinder in the big classThe following is a reflection on the big class's lesson plan on spheres and cylinders:
** 1. Strengths **
1. ** The teaching concept of taking children as the main body is reflected **
- By letting the children play and operate the activities to understand the sphere and cylinder, it greatly increased the interest of the children. For example, children could naturally touch and explore spheres and cylinders while playing with paper and plasticine. Children could better understand knowledge in this play-learning and play-learning mode.
- In the operation stage, the initiative of the child was exerted, such as letting the child roll, stack a stack of spheres and cylinders, and discover their characteristics by themselves, which helped the child to actively construct knowledge.
2. ** Habit Cultivation **
- In the play segment, they focused on the cultivation of children's habits. For example, when playing with paper, pass it one by one. When playing with plasticine, play the role of a group leader. This helps to cultivate good behavior habits and teamwork in children.
3. ** Comply with early childhood development needs **
- Taking into account the characteristics of the children in the upper class, such as the strong desire to explore and the ability to use language to communicate, the activities designed could meet the needs of the children's cognitive, ability, and emotional development. For example, in the activity, the children were allowed to perceive the characteristics of the sphere through personal experience, exploration, experiment, and operation. This was in line with the characteristics of the large class children's strong desire to explore the surrounding things.
- The activity could stimulate the child's interest in exploration. For example, in the process of finding the sphere and cylinder in life, the child could cultivate the habit of caring about the things around him.
4. ** Achievement of teaching objectives **
- During the activities, the children could better understand the basic characteristics of the sphere and cylinder, such as knowing that the sphere could roll in all directions, that it was round in all directions, that the upper and lower surfaces of the cylinder were circles of the same size and the upper and lower surfaces were the same thickness, etc., which basically achieved the teaching goal of letting the children understand the basic characteristics of the sphere and cylinder.
- Through game activities such as " Magical Box ", children could distinguish between spheres and cylinders, consolidating their knowledge. This helped children understand the concept of spheres and cylinders and retain them for a long time.
5. ** Good interaction between teacher and child **
- During the activity, the child could cooperate well with the teacher, and the teacher could also adjust the content of the activity according to the needs of the child. For example, when the child raised questions or made new discoveries, the teacher could guide and respond in time.
6. ** Materials prepared **
- There were all kinds of materials prepared, such as all kinds of rubber balls, table tennis balls, paper tubes, cans, bottle caps, newspapers, etc. There were also wall decorations, children's books, etc. These materials allowed children to perceive the characteristics of spheres and cylinders from different angles.
** 2. Weakness **
1. ** In terms of developing children's abilities **
- Children's listening ability and self-control ability still need to be strengthened, which may affect the teaching effect. For example, when explaining the characteristics of spheres and cylinders, if children don't listen well, they may not be able to accurately understand the concepts.
2. ** Organization of teaching sessions **
- The search for spheres and cylinders in life was not well organized and disorderly. The organization method needed to be improved to improve the teaching effect of this segment.
3. ** Event time control **
- If the activity time was not controlled well, sometimes the activity time was too short, resulting in insufficient exploration and consolidation of knowledge, which may not fully meet the learning needs of the child.
4. ** Depth of teaching content **
- The teaching content was not rich enough for the children. More games or inquiry content should be added to deepen the children's understanding of the sphere and cylinder.
