electric charges and fields class 12

The following are some of the main points of reflection on the science lesson plans of the five major areas: ** 1. Achievement of teaching objectives ** 1. ** Knowledge and Skill Target ** - If the goal of the lesson plan was to let the child understand a certain scientific phenomenon (such as the characteristics of water), it was necessary to see if the child really understood it. For example, in the teaching of water, whether children could accurately say that water was colorless, odorless, transparent, and other characteristics. If it didn't work, it might be because the teaching method was not intuitive enough. For example, it was just oral explanation and the children were not allowed to observe the water sample personally. - As for the skill goals, it was to train the child's observation and operation skills. If the goal is to let the child learn to use a certain tool (such as using a magnifying glass in leaf observation) to observe the characteristics of the leaves, but the child is not proficient in the operation, it may be due to insufficient practice time or the teacher's demonstration. 2. ** Emotions, attitudes, and values ** - For example, in the lesson plan about vegetables, the goal was to let the children know that eating more vegetables was good for their health. When reflecting, they had to consider whether the children had a more positive attitude towards eating vegetables after the activity. If the child did not show this change in attitude, it might be because there were not enough elements in the teaching to attract the child, such as stories, games, etc., which could not effectively convey the benefits of eating vegetables. ** 2. Teaching content ** 1. ** Selection of content ** - Whether the content is suitable for the cognitive level of middle class children. For example, in the teaching of some scientific concepts (such as the role of leaves in plant growth), if the concept was too complicated for children to understand, they needed to simplify the content or adopt a more suitable way for children to understand, such as through metaphor (leaves are like the small mouth of plants, used to absorb sunlight and air). - Whether the content was interesting enough to attract children's attention. If the teaching content was about how to play the ball, the child might not be interested if it was just a simple introduction. He could add some competitive or cooperative elements, such as group competition to make the ball stand firm. 2. ** Organization of content ** - Whether the logical order of the teaching content is reasonable. For example, when introducing the edible parts of vegetables, children should first be introduced to common vegetables and then understand their edible parts in depth. If the order was reversed, children might be confused. ** 3. Teaching methods ** 1. ** Teaching Method ** - Whether the teacher's explanation was clear and concise. If the teacher used a lot of complicated terms in the process of explaining the water cycle, the child might not be able to understand. 2. ** Visual Teaching Method ** - Whether the use of visual aids such as real objects, pictures, and PPDs was effective. For example, when displaying a variety of leaves, if the leaves were placed in a messy manner, or if the PowerPoint picture was not clear enough, it might affect the child's observation. - In the experimental method, whether the experimental design was reasonable. For example, in the water circulation experiment, if the experimental equipment was too complicated or the operation steps were not clear, the child might not be able to successfully complete the experiment and achieve the purpose of understanding knowledge through the experiment. 3. ** Interactivity Teaching Method ** - Whether or not the Q & A session was effective. For example, when asking children to answer questions about how to play a small ball, if the questions were too broad or the guidance was insufficient, the children's answers might be more limited. In group activities or discussion sessions, the interaction between children was positive. If the participation of children was not high, it might be that the teacher did not give enough guidance or incentive measures. ** 4. Child's performance ** 1. ** Participating Rate ** - Observe the child's participation in the entire teaching activity, whether it is active or passive participation. If the child's participation in the leaf growth process was low, it might be because the activity was not attractive enough, or the child did not understand the requirements of the activity. 2. ** Individual differences ** - He had to pay attention to the individual differences between children. Some young children might understand scientific knowledge faster, while others might be slower. For example, in the teaching of eye protection, some children may be able to quickly tell many ways to protect their eyes, while some children need more guidance. Teachers need to adjust teaching strategies according to this difference. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is a lesson plan for the middle class science fan: ** 1. Activity Target ** 1. Let the children understand the basic structure and working principle of the electric fan. 2. Cultivate the child's observation and exploration spirit. 3. Arouse children's interest in scientific phenomena. ** 2. Event preparation ** 1. Various types of electric fans (such as tabletop, floor-standing, etc.) are available for children to observe. 2. Simple pictures or videos about the structure and working principle of the electric fan. 3. Some simple tools (such as a screwdriver, etc., used by the teacher). ** 3. Activity process ** #(I) Introduction 1. The teacher guided the children to recall the scenes of using electric fans in their daily lives and asked,"Children, when it's very hot in summer, what do we use to cool ourselves?" The topic of the electric fan was brought up. #(2) Observing the electric fan 1. The teacher showed the different types of electric fans in front of the children and asked the children to observe them carefully. Then he asked,"Children, what are the components of the electric fan?" Guide the child to find the fan blade, motor, base, net cover and other parts. 2. The teacher operated the electric fan and asked the children to observe the direction and speed of the fan blades. What's the difference between spinning fast and slow?" #(3) Explain the working principle of the electric fan 1. Combining the pictures or videos that he had prepared earlier, he explained the working principle of the electric fan to the child. For example, tell the children that the electric motor will make the fan blades rotate after being energized, and the rotation of the fan blades will produce wind to make us feel cool. It could be explained with a simple analogy, such as "The motor is like a small magic box. Once it is energized, it can make the fan blades spin like a small windmill." 2. Teachers can use small tools to open the back cover of the electric fan (pay attention to safe operation), so that the child can have a simple look at the motor, but do not go deep into the internal structure to avoid being too complicated. #(IV) Children's Free Exploration 1. Give the children a certain amount of time to observe the electric fan again at a close distance under the teacher's safety supervision, touch the fan blades, look at the net cover, and so on. 2. Children were encouraged to discuss their discoveries about electric fans. #(5) Activity summary and reflection 1. The teacher guided the children to review the activity and asked,"Children, today we learned about electric fans. Who can tell me what parts of an electric fan are there?" "Why is there wind in the electric fan?" Consolidating the knowledge learned by children. 2. ** Reflection Part ** - During the activity, the child was more interested in observing the electric fan, but it was difficult to understand the working principle. Next time, he could prepare more vivid teaching aids or carry out simple simulation experiments, such as using a small fan model and a battery for a simple power-up demonstration to help children better understand. - During the free exploration session, some children were too excited and had some unsafe touching behaviors (such as trying to put their hands into the net). In the future, safety rules must be emphasized again before this segment, and teachers must strengthen their inspections. - In the activity introduction section, the children could share what the electric fan in their home looked like. This could better mobilize the children's existing experience and increase their participation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Apartments in different areas had different electricity charges. In Shen Zhen, after the commercial water, electricity, and gas prices of business apartments and other residential apartments were guaranteed, they would apply to the relevant enterprises with the project confirmation letter. After the review and approval, they could be implemented according to the resident standards. According to the regulations of Guangdong Province, commercial apartments and other residential buildings are used for residential households. If the meter reading is charged separately, the residents shall apply for it. After verification by the power supply unit, the residential electricity price shall be implemented. At present, the monthly electricity fee standard of most residential apartments in Guangdong Province is between 0.7 - 1 Yuan/kWh, and the civil electricity fee standard is mostly 0.58 - 0.63 Yuan/kWh. For those used for commercial operations, the corresponding industrial and commercial electricity price shall still be implemented. In Guangzhou, tenants encounter additional fees such as management fees on the electricity bill. In addition, the student apartments of colleges and universities in Chongqing will be charged to students at a price stipulated by the state for the part that exceeds the quota. The quota is 5 kWh of electricity per student per month. Also, after the landlord charged the tenant's electricity bill, the court ruled that the electricity bill collected by the increase should be returned. For example, if a tenant was charged by the landlord at a price of 1.1 yuan per kWh, this behavior violated the law prohibiting the addition of other fees to the electricity bill.
