You may have some misunderstanding, but I believe that he was an ancient Greek philosopher, not a wizard. There were many classic sayings by him, such as: - "If a person looks at others from their own standpoint, they will often misjudge others. I never judge people by how they treat me, but by how they treat others." This reminded people to avoid judging others from their own subjective standpoint and to judge others by observing their attitudes towards the people around them. - "You yourself are a gold mine. The key is to see how to discover and put yourself in an important position."

Teaching plan and reflection on the trial lecture of chemical oxidoreduction course

#"Oxidation-reduction Reaction" Trial Teaching Plan ##1. Teaching objectives 1. Students will be taught to understand the concept of oxido-reduction reaction from a macro perspective. They will be introduced through examples to trigger cognitive conflicts. They will be able to grasp the basic concept of oxido-reduction reaction based on macro substances. 2. To guide students to understand the nature of the oxidoreduction reaction from a microscopic perspective, to build a cognitive model, to use the atomic structure diagram to describe the microscopic process of electron gain and loss and deviation, and to use the "double-line bridge" and "single-line bridge" to analyze the electron transfer process, so as to improve their understanding of the oxidoreduction reaction. 3. With the help of concrete examples, the students will be able to understand the basic concepts such as oxidiser, reducing agent, oxidization reaction, reduction reaction, etc., and understand the philosophy of the unity of opposites contained in them and its important value in scientific research. 4. Cultivate the students 'ability to apply the basic model of the oxido-reduction reaction to solve practical problems. ##2. Difficulties in Teaching 1. ** Main point ** - Accurately understand the concept of the oxido-reduction reaction. - Learn to recognize the oxido-reduction reaction from a macro perspective (the rise and fall of the element's valency). - Able to understand the nature of the oxido-reduction reaction from a microscopic perspective (electron transfer). 2. ** Difficulty ** - Understanding the nature of the oxido-reduction reaction from a microscopic perspective. ##3. Teaching Method Lectures, conversations, and group discussions. ##4. Teaching process ###(1) Introduction of revision 1. Question: According to the material classification standard, classify iron dioxide and copper dioxide. According to the material transformation law, convert them into metal elements and write the reaction equation. According to the basic reaction type, classify the reaction. 2. Guide students to think as they answer: When the existing standards cannot accurately classify responses, new dimensions will appear. ###(2) New Knowledge Exploration 1. ** Observe and summarize the characteristics of the oxido-reduction reaction ** - Question: Observe the reaction between carbon dioxide and iron dioxide. From the perspective of oxygen gain and oxygen loss, what kind of reactions do these two reactions belong to? What were the characteristics of these two reactions from the perspective of elemental valency? - On the basis of the students 'answers, he concluded that the chemical reaction of oxygen gain and oxygen loss was called the oxidoreduction reaction, which was characteristic of the rise and fall of the chemical valency of the elements. - Another question: Write down the equation for smelting copper by "wet smelting" and analyze if it is an oxido-reduction reaction? To further summarize, the chemical reaction of the element's valency change was the oxidoreduction reaction. - What were the four basic reaction types that they learned in middle school? What was the relationship between the oxido-reduction reaction and it? Guide the students to use the Venn diagram to represent the relationship between the two. 2. ** Exploring the Nature of Oxidation-reduction Reaction ** - Student activity: Using the formation of NaCl2 as an example, explore the nature of the oxido-reduction reaction based on the atomic structure. The teacher guided the students to think about the relationship between the atomic structure, the gain and loss of electrons, and the deviation of electron pairs, so as to understand the microscopic process of the oxidoreduction reaction. ###(3) Class Practice Give some chemical reaction equations for students to judge whether it is an oxido-reduction reaction. If it is, point out the oxidiser, the reducing agent, the oxidiser reaction, and the reduction reaction. ###(4) Summing Up 1. Guide the students to review the concept, characteristics, and nature of the oxidoreduction reaction. 2. It emphasized the relationship between the concepts of oxidiser, reducing agent, oxidization reaction, and reduction reaction. ###(5) Assignment 1. Basic homework: Complete the relevant exercises in the textbook and consolidate the basic concepts and judgment methods of the oxidoreduction reaction. 2. "Additional homework: Find examples related to the oxido-reduction reaction in your life and analyze the oxidiser, the reducing agent, etc. #Reflection on the Trial Lecture of Oxidation-reduction Reaction ##1. Strengths 1. ** Various teaching methods ** - The revision method was used to consolidate the knowledge that the students had learned before, and by triggering cognitive conflicts, the content of the new lesson was naturally introduced. The combination of lecturing, conversation, and group discussion helped to mobilize the enthusiasm of the students, making the classroom atmosphere more active, and also conducive to the students 'understanding and mastery of knowledge. 2. ** Clear logic ** - In the new knowledge exploration segment, he gradually explained the characteristics of the oxidoreduction reaction to the essence. First, the students would be taught to understand the characteristics of the oxidoreduction reaction from the macro perspective of the change in chemical valency. Then, the students would be guided to explore its essence from the micro perspective. This would conform to the cognitive laws of the students and help build a complete knowledge system. 3. ** Focus on interaction ** - In the classroom teaching process, through questions, group discussions and other ways to interact with students, give students timely feedback, can guide students to think actively and participate in the classroom. ##2. Deficiency 1. ** Time Control ** - During the student activity segment, due to the fact that some students had forgotten the knowledge of atomic structure, it took more time to explore the nature of the oxidoreduction reaction. As a result, the final classroom practice and summary segment were a little rushed, and the students were not given enough time to think and summarize. 2. ** Difficulty Breakthrough ** - Although the students were guided to understand the nature of the oxidoreduction reaction through examples, it might still be difficult for some students with weak foundations to understand. In the future, more intuitive demonstration or analogy could be added to help these students better break through the difficult points. 3. ** Expansion and Extension ** - In the homework assignment section, although there was an expansion assignment, there was not enough hint on how to guide students to analyze the examples of oxidoreduction reactions in their lives. In the future, he could give a simple example of how to analyze life examples in class so that students could better complete their homework. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The Landlord and the Servant

Landlords and long-term workers were two social roles in feudal times. The landlord owned a large amount of land and other means of production, and the long-term workers were employed by the landlord to work for him. In traditional stories, the stories of long-term laborers and landlords mostly reflected the contradictions and struggles between the two. This kind of story was compact and vivid, with contrasting characters. It was often humorous and witty. For example, in the story of the two brothers, the elder brother was honest and honest. He was deducted from his annual salary because he couldn't do three difficult things that the landlord deliberately mentioned. The younger brother was smart and witty. When he was helping his brother, he cleverly stumped the landlord three times. Not only did he get double the salary, but he also got back his brother's salary for the previous year. Long-term laborers often took advantage of the landlord's greed, stinginess, cunning, and stupidity to seize the loopholes in the landlord's conditions and words when the two parties signed the contract and punish the landlord at his own game. Most of the stories ended with the long-term laborers winning and the landlord being teased or punished. In real life, long-term workers worked very hard in the landlord's house. There were no rest days. They usually had to work for a year before they could get some food crops or wages to bring home. For example, some long-term workers who had a good harvest at the end of the year at the landlord's house, after receiving their wages, wanted to rush home overnight because of excitement, but encountered misfortune on the way. In addition, there were also stories based on the landlord and the long-term worker. Through the new story, some social and economic phenomena were reflected, such as the landlord selling the house to the long-term worker and then changing the name to continue collecting fees, as well as a series of subsequent actions to use the long-term worker to obtain benefits.
