tenth year of teaching

Chapter 85
"Teacher, you just talked about using K to explain the equilibrium movement conditions. So for the relationship between Qc and K, the concentration directly changes Qc. Based on this, it can be inferred whether the temperature changes K so that Qc and K are no longer equal. How about moving the reversible reaction?" Li Lei explained his point of view with a questioning tone.

"What about pressure? How do you explain it?" Wang Yi stood up and asked.

"Pressure cannot change K, because K is only affected by temperature." Li Lei hesitated.

"The most direct change in pressure should be the volume of the gas, so I thought it should change the concentration of the substance, thereby changing Qc." Ma Ziwen stood up.

"Then the pressure needs to consider the concentration on both sides of the reaction, which is not as easy to understand as a single concentration change. How should we explain it?" Wang I continued to ask.

"I think we should look at which side has the greater impact. We can draw a conclusion by looking at the ratio of the numerator or the denominator. If the impact on both sides is the same, it is as if there is no impact." Li Lei concluded.

Some people in the audience were pondering, and some were talking quietly. Chu Xia didn't say a word, waiting for the results of everyone's discussion.She often has surprise moments like this. The teaching progress of Class A is far higher than that of Class B. There are 16 classes, 4 Class A, one in liberal arts and three in science.The elite figures in the grade are gathered together, and every time a question is raised, the students will solve the discussion by themselves through continuous negative discussion.

There is a saying that was circulated during everyone's student days, that teachers prefer top students.She scoffed at this when she started working in early summer. She decided to learn from Lao Geng and treat students equally.But after you have been teaching for a long time, you will realize how difficult it is. You can understand it immediately after speaking a sentence, and be able to draw inferences from one example.I talked about it seven or eight times, but I was still confused, and I failed to pass the test every time I asked questions.

One of the oldest jokes circulating on the Internet among teachers is: "The teacher lectures at 4G speed, the top student listens at wifi speed, the top student memorizes at 3G speed, some stare at 2G speed, and some As I listened, I was disconnected, and some were in airplane mode, or not online at all, and some even shut down and disconnected immediately during class."

How do you let the old mother's heart take care of itself?Which teacher is not willing to promote each other and make progress together with students in their profession?However, the grades [-], [-] and [-] admitted to high schools have clearly stratified students, and so have teachers.Even if they graduate from a key normal university, a few or more years later, teachers from key high schools will win various awards and their professions will advance rapidly, becoming either district backbones or city-level special-level teachers.In any ordinary school you can find a few city-level backbones, but the students' grades are simply not enough to support them in achieving such results.

As a result, teachers in ordinary schools became more and more willing to be mediocre, and spent most of their lives trying to become a high-level student.Every day’s energy is used to manage being late, going to class, finishing homework on time, etc. The head teacher spends more energy on helping children from special families do corrections and doing things that parents have not done, so they become more and more mother-in-law and mother-in-law. have become increasingly disconnected from new educational concepts.Children don't appreciate it, parents don't support it, and teachers grow old complaining day by day.

Ever since I took Class B in early summer, I have been thinking about my career goals.Instead of competing for the few qualifications to teach Class A, it is better to find another way and find a path that no one has yet taken.In the first year of high school, he tried to apply for a project, but the district did not pass it. Ma Liqiang made him a school-level student and asked him to study more with him.In the past six months or so, I took her to the city and participated in several project reporting meetings, and she gradually became enlightened in early summer.

At the same time, with the help of old teachers Dong and Zhang Junguo in teaching, Chu Xia gradually became clear about her own ideas.Zhang Junguo used to teach in a key middle school in Hebei Province, and he had a lot of water in his stomach. He also published some articles in magazines and newspapers.Chu Xia asked for advice very sincerely, and Zhang Junguo gradually let down his guard and began to seriously guide this young teacher who was patiently learning.

On this day, Ma Liqiang called to inform Chu Xia that the application for the second project had been approved in the district, and Zhang Junguo's application of the group competition mechanism in the chemistry classroom was jointly approved as a district-level project.

I couldn't help but be excited in early summer. I bought some fruit gifts to send to Zhang Jun's country over the weekend. I thanked the teacher for his help and guidance. Naturally, Ma Liqiang's share was also included.The etiquette is light on affection, and the two master-level figures over forty who have been immersed in officialdom will naturally not take these little things in their eyes. They just feel that it is difficult to see such young people who are willing to learn and have a sincere attitude. up.

Principal Zhang looked at the list of teachers who applied for project approval this year and was a little surprised that Chu Xia was on the list.She is the only young person in the entire list. Without more than ten years of work experience, it is difficult to initiate projects at the district level.He knew better than anyone else that it seemed that he had underestimated this girl before.

Chu Xia was not good at words at first, but thanks to reading a lot of books when I was a child, I still had some writing skills.Unexpectedly, it actually helped my career development.This year, the training class of the First Normal University was recruiting students, and Chu Xia signed up without hesitation. She hoped that she could go further on the road of teaching and research.

After the April exam, Wang Haoqiang held a large-scale student commendation. The biggest difference this time was that he invited Chen Long, who had always ranked first in grade, and his mother to give a lecture on study and family education.

Chen Long was in Class 6 taught by Lao Zhang. In early summer, he was very interested in this boy who was 1.8 meters tall and had a very dashing appearance. According to Lao Zhang, he was transferred from the city.Many people wonder why they transferred from the city to a third-rate high school in the outer suburbs.There are different opinions out there. The most widely circulated one is that Chen Long had a girlfriend at his original school, but they broke up later without clear distinction. The girl tried to die for him, and the quarrel was too big, so she had to change schools, and she was hastily transferred to the No. [-] Affiliated Middle School. Come.

But if you are a dragon, you will not be buried. Chen Long, who has been at the forefront of his grade since the first year of high school, immediately occupied the first place in the grade after the liberal arts and sciences were separated in the second year of high school and no longer wavered.I don’t know if he was really hurt in his last relationship, but this boy rejected all suitors. Apart from studying, he just played basketball with a few good buddies for fun.

Chen Long's account is very simple: "I don't admit that I have any extraordinary IQ. I just learned part of it in advance, listened to the lectures based on the questions in class, and sorted out and corrected my mistakes after class."

"You study in advance. What do you study? How do you study? How much do you study? Can you give me an example?" Wang Haoqiang asked on behalf of everyone. He was a little depressed. It was impossible to force such a boy to write a manuscript in advance. It would be better to Come to the scene to answer reporters’ questions.

Chen Long pondered for a while, "Let's take physics, for example. Many science students think this subject is difficult. In fact, the teacher explained it very clearly. It is just a few big pieces, and the knowledge is very comprehensive. For example, in mechanics, the most important thing is force analysis. , such as orthogonal decomposition. I don’t have any tricks, but I read the book in advance during the vacation, draw out the parts I don’t understand with a pen, and put question marks. When the teacher explains, I will clear up the understood content one by one, and the rest is to do the questions. I usually like to do the questions at night before going to bed. Everyone’s habits are different. Some people like to memorize before going to bed, but I can’t do it. I will feel sleepy while memorizing.”

Chen Long tilted his head, as if he remembered something funny, grinned, and continued: "I will do the exam questions again when I go home from self-study. I won't be sleepy when I do the questions. Usually I don't get them all right the first time. I will do it a second time. As long as I got it right the first time, I will basically throw it away and not read it twice. I usually don’t buy additional review materials. They are all given by the teacher in class, but I will do them twice in one exercise book. I will definitely cut out the more classic ones and those that I still have some questions about when I did it the second time and compile them into a book as key review materials before the big exam."

"Where do you find the time to do these things? I feel like I can't finish my homework every night." A girl in the audience asked.

"If you're just stuck in homework, it's impossible to find your own rising point. I don't do all the homework."

Wang Haoqiang cleared his throat awkwardly and motioned Chen Long to stop with his eyes.

Chen Long smiled and continued: "Of course, after I pass the basics, I can discuss homework with the teacher, but unless there are special circumstances, I will usually complete the homework. Time is not a problem, if you set the meal time to 20 minutes every day Within minutes, you can do it naturally.”

"Twenty minutes, isn't that too exaggerated? It's not possible to choke to death." Li Hai muttered, and the audience started to talk.

"It's three meals in 20 minutes. I usually go to play ball after class. On the way back, I buy a piece of bread and have a meal in 2 minutes." Chen Long smiled confidently.

"You're so crazy, cut and pull!" Li Hai was disdainful.

Wang Lulu glanced at him sideways: "If you can get his grades, you can drag him!"

"No, why are you always targeting me? Why do we have a grudge?" Li Hai bared his teeth.

Wang Lulu rolled her eyes and turned away from him. Li Hai was so angry that his tooth ached, but Zhang Yan looked at the two of them funny.

　Inverted V started to be released in the second year. I was very embarrassed. I felt that many stories had not been fully written in my heart.I have been teaching for ten years and recorded the warm stories around me as a bystander. It is not so thrilling and ups and downs, but it can really be kept in my heart to warm every day.It is the first time to tell a story, the first time to sign a contract, and the first time to put it on the shelves. Thank you Qidian Yunqi platform, thank you editor Fengzao, and thank you for this platform to tell you stories about the campus.Whether you like it or not, leaving traces is a friend. I hope you can get some suggestions and opinions. 2019.10.1 records such an exciting and ordinary day on the 70th birthday of our great motherland.
