20 years of teaching

Chapter 218 The Talent of Teaching and Educating People

Hearing Chief Yang's comments, Wang Baida curled his lips secretly with disdain on his face. He despises this kind of people who can only talk big words the most.

He once participated in an open chemistry class at the county level, and Section Chief Yang also commented on that open class. He remembered that Section Chief Yang’s comments on the chemistry class and today’s comments on the physics class were almost exactly the same...

After pondering for a while, Liu Fuliang finally found a shortcoming of Lin Feifei. He interrupted others' praise and said loudly: "This is not a complete class. Lin Feifan talked too much nonsense and wasted a lot of class time. Section knowledge is not finished."

Although Wang Baida is a chemistry teacher, he has taught physics for many years, and he knows that Liu Fuliang is picking bones in eggs.

To put it in a bad way, it's like playing the piano indiscriminately.

Wang Baida always wanted to be promoted to be the vice principal of Jinghu Junior High School, and he had to get the help of Liu Fuliang, so he didn't dare to correct Liu Fuliang's wrong views...

Fang Yongzhi admires Lin Feifei now. He feels that Lin Feifan's class is not only a successful open physics class, but also a very good music class. The processing of modernization has reached the pinnacle.

Fang Yongzhi is a very honest person, and he corrected Liu Fuliang's erroneous remarks: "The teacher's reference book stipulates that "The Characteristics of Sound" needs to arrange two class hours, the first class time is about pitch, and the second class time is about loudness. and timbre, Lin Feifan’s arrangement of the classroom content is very reasonable.”

Liu Fuliang glared at Fang Yongzhi, his face was frosty, damn, how dare you refute the director of the education committee, next time labor and management will give you good fruit to eat!
Lin Feifan organized the students to move the equipment to the next classroom. The next class of the second class of junior high school is physics class. They need to use these equipment and bring other equipment to be used.

"Are you going to have another class in the next class?" Yin Qinsong asked.

Lin Feifan said: "Well, Class [-] of the second class of junior high school today learned the knowledge of pitch. Class [-] finished yesterday. Class [-] will learn loudness and timbre in this lesson."

Yin Qinsong was overjoyed immediately, and said loudly: "Let's continue to listen to a complete section of "The Characteristics of Sound" to see what wonderful performances Lin Feifei will have next."

"Okay, okay!" Wang Baida clapped his hands and hurriedly returned the borrowed books to his classmates in the second grade (second) of junior high school. He also borrowed a few physics textbooks from class one (first grade) of junior high school, distributed one to each student, and arranged for the students to Place stools at the back of the classroom in Class Two ([-]) of junior high school.

As the head teacher of the second grade of junior high school, Wang Baida wanted to see what wonderful performances his students had in Lin Feifan's class.

Liu Fuliang's eyes turned green, and he said with a sullen face, "I'm sorry, I can't attend this class. I have to go to the toilet to defecate."

No matter how wonderful Lin Feifei's class was, Liu Fuliang was not interested. On the contrary, the better Lin Feifei taught, the more disturbed and frightened he became.

Liu Fuliang felt that Lin Feifei, a rising star in the education field, was afraid that his wish to withdraw and merge with Jinghu Junior High School would be smashed to pieces.

Learning any skill and engaging in any profession, there are always a few gifted people.

Talent refers to talent, that is, outstanding aptitude, which is born with and endowed by heaven.

Talent is a growth characteristic that is already possessed before growth. It is a natural ability to be good at certain things or fields, so that it can grow faster than others with the same experience or even no experience.

Talent has uniqueness, particularity, and perfection.

Liu Fujiang believes that Lin Feifei has a very high talent in teaching and educating people, and Lin Feifei's personal development will be unstoppable, thus effectively driving the development of Jinghu Junior High School.

Liu Fuliang, who was squatting in the toilet, frowned and thought. Although he pulled down his pants, he didn't excrete anything. After thinking about it, he thought that Lin Feifan's development would be prevented without special measures.

He decided to transfer Lin Feifan out of Jinghu Junior High School at all costs, and even took risks with Wang Yuezhi to do some illegal activities to frame Lin Feifan, even if he had to pay some price, it was worth it...

Otherwise, all good visions will be ruined...

The physics class of the second year of junior high school has begun.

Lin Feifan first asked four questions. To Wang Baida's delight, the children in his class answered the questions very actively, almost all of them raised their hands.

Lin Feifei only called four children by name, one child answered a question, and each of them gave the correct answer smoothly.

The last problem is to analyze and compare the different characteristics of the sounds of cows and mosquitoes from a physical point of view.

Liu Xiaojun, the sports committee member of the second grade of junior high school who answered the question, Liu Xiaojun is the son of Liu Shoulin and the cousin of Liu Huihui.

Liu Xiaojun is 16 years old this year. His primary school grades are relatively poor. He repeated the first grade and the fifth grade, so he is older than most of his classmates.

Liu Xiaojun, whose grades are very average, not only answered that the pitch of the two is different, but also that the loudness of the two is different, and explained which factors are related to the pitch and loudness.

In the last class, only the knowledge of pitch was covered, and it was entirely self-study to answer questions about loudness properly.

His grades in other subjects were not satisfactory, but Liu Xiaojun has a strong interest in physics.

Following Teacher Lin's instructions, Liu Xiaojun previewed the unfinished part of "The Characteristics of Sound" and memorized the knowledge of this chapter thoroughly.

After Lin Feifan praised Liu Xiaojun, he began to teach new lessons.

In daily life, the sound of cows is louder, and the sound of mosquitoes is softer. From a physical point of view, the essence is that the strength of the sound is different.

In physics, the strength of sound is called loudness, which is the subjective perception of the size of the sound received by the human ear.

A ping-pong ball is suspended with a thin wire on an iron stand, and a tuning fork is placed under it. This is a demonstration experiment in the textbook, and it is used to explore the factors related to the loudness.

This time, Lin Feifan did not do the experiment himself, but invited two classmates to complete the demonstration experiment.

Hit the tuning fork with different forces, and observe the distance the ping-pong ball is bounced by the tuning fork. It is found that the harder the beating, the louder the sound from the tuning fork, and the farther the ping-pong ball is bounced.

In physics, amplitude is used to describe how much an object vibrates.

This experiment shows that the loudness is related to the amplitude, the larger the amplitude, the louder the loudness.

Lin Feifan once again conducted a self-created experiment to strengthen this knowledge point. Put a basin full of water on the lecture table, lightly tap the tuning fork, and immediately put it into the water, and the water surface rippled.

Sitting in the middle of the first row, Wang Qinqin half stood up, stretched her neck and looked at the washbasin with relish...
