Chapter 332 332. Twist
An excellent teacher may have the ability that no matter how difficult things are, he can explain them in simple terms.
There are absolutely very few such people. Zheng Zhiyong enjoyed the educational resources that are definitely among the best in South Korea during his growth. Isn't there a lot of things he doesn't understand?
Zheng Zhiyong is not a smart person, and his teaching level cannot be compared with those real famous teachers. Who among his students is really talented?He originally wanted to try to explain the relationship between vectors, cosines, and dot products, but that thing is not intuitive at all. Normally, it may take half a class to explain clearly why this is the case, Zheng Zhiyong Where is that time?
Not every formula theorem needs to explain why it is done so that people can remember it clearly and firmly, just like the cosine theorem has been used countless times by high school students, and a "prove the cosine theorem" in the college entrance examination can make many candidates cry.Many concise conclusions in science and engineering are based on the long-term accumulation of experience and in-depth thinking of the predecessors. Later generations do not need to repeat the demonstration process step by step, just get used to it.
This is exactly what Zheng Zhiyong neglected-students have no time to "use habits".Those formulas and theorems that generally do not need to be proved again, if they are not popular to the extent that "the distance between a point and a straight line is the shortest vertically", can pose obstacles to students.
"But this is a very important theorem in the calculation of the space Cartesian coordinate system. Even if you don't understand it, please do some examples with me first."
After a moment of stiffness and frustration, Zheng Zhiyong regained his composure and began to forcibly brush up the amount of questions.During the interview after class, Zheng Zhiyong was not so calm: "My question, what I can understand, I think others will understand. A teacher should not make such a mistake." No matter how routine the Cartesian coordinate system is, the three-dimensional geometry related to it can be regarded as a difficulty.
Min Yalin squatted outside the camera, and asked him half-jokingly: "Does thinker mean that he has a better understanding ability?"
"It took several classes to understand...so I said I was shameless," Zheng Zhiyong smiled wryly, "People who often arrive late and leave early, but basically have completed three years of high school, how can they understand time?" If you don’t have a lot of money, you will still have a shortage in the end.”
"A thinker who has not got rid of the inertial thinking of full-time students" can become a label added to his head later.
"You can't see it in class," says the writer.
"Everyone's time is limited," Zheng Zhiyong said solemnly, "Even if something is different from the expectation, we must stop the loss in time and try our best to ensure the efficiency of the classroom."
Zheng Zhiyong's class schedule is very tight, and each class has its own tasks, so there is not so much time to procrastinate.After finding that the method of finding the angle between vectors seemed unreasonable, he immediately shifted the teaching focus, began to introduce various situations where this method was used, and demonstrated the calculation process with a pen by himself. Dot multiplication and modulus to find the cosine can get two The angle between the vectors, if the two vectors are normal vectors, it can be used to calculate the angle between the planes, the result of the dot product is 0, the relationship must be vertical, and the general practice of auxiliary lines...
To put it bluntly - typical cramming.
Unless you are particularly gifted or interested in learning, it is normal for you to forget about it after understanding it during the lecture. What's more, this time is a test of spatial imagination and rote memorization of formulas?
Zheng Zhiyong once again used his signature - data statistics and analysis. He released four classic examples in the ppt at one time. He wanted to explain the solutions and compare their similarities and differences, but this time it was not as smooth as before. Zheng Zhiyong made random checks, and then had to keep up with the teaching progress of solid geometry. Mental work is also labor. Now the students' nervous fatigue can be compared to the muscle condition of an otaku who ran two kilometers.
"A case that is often considered is the proof of perpendicularity. What are the conditions to prove that the vector is perpendicular to the plane...?"
There was a brief pause in Zheng Zhiyong's words, although he continued to speak calmly after the pause, but everyone is a keen person, how could they not feel something wrong?
The camera immediately followed Zheng Zhiyong's condensed gaze just now, and aimed at Tian Zhengguo who had already narrowed his eyes.
The classic scene of "sleeping in class" finally appeared!
Tian Jungkook's reaction is not slow, he has lived in front of the camera for three years, even if he is not proficient in this skill, he still has a basic ability to perceive the surrounding atmosphere.Before the camera came to a steady stop on his face, Tian Zhengguo opened his eyes, but the eyes were still a bit dazed, and when he opened his eyes, he forcibly cheered himself up so that his body trembled obviously, which could still be regarded as an obvious "waking up from sleep in class" material.
It's a pity that Jungkook has big eyes, and he usually has a more energetic image in BTS. If he is like infinite Kim Sung Kyu, he looks like he is asleep even when he is awake, and he will not be caught so easily.
Zheng Zhiyong glanced at him with a smile, and asked the question he just mentioned again: "What is the condition to prove that the vector is perpendicular to the plane?"
Jin Yelin: "The vector and the two vectors on the surface are both perpendicular."
Zheng Zhiyong nodded: "What is the relationship between the two vectors on the plane?"
Zhou Jieqiong: "Cross." As she spoke, she raised her arms and made a big "x".
Zheng Zhiyong nodded again: "Now, establish a coordinate system in the second question to prove the first sub-problem."
Sooner or later, there will be "sleepy" plots, but how to do it is a matter of knowledge.Zheng Zhiyong once helped Min Yalin ask everyone's wishes, but he didn't get a positive response, and he didn't force it anymore.
"Maybe it will be more difficult and more intense in the future, and some people's energy will not be able to keep up." Zheng Zhiyong gave everyone a vaccination in advance. Trainees or artists often sleep in class at school. The reasons include how much sleep is accounted for, and others How much will it account for, everyone knows, "What if, I mean, what if that happens, what do you think is better to deal with it from the perspective of variety shows?"
So they discussed the effect of variety shows, and Zheng Zhiyong's suggestion was finally adopted—although I don't know if it is to take care of the elderly: "Don't reality shows like to make growth stories? If anyone doesn't stick to it, they will work harder when they go back. One point, try to solve the unresolved problems next time?"
It’s normal to not understand things that you didn’t understand at the beginning, but it doesn’t look good on the show.
Finally someone couldn't hold it anymore.
On Zheng Zhiyong's face, he looks like a good teacher who is tireless in teaching, but in his heart, he feels that he belongs to a variety show.After the questions were set, he also walked quietly to Tian Zhengguo's side to watch him do the questions.
Tanaka: ...
His expression is the classic "I'm under a lot of pressure when the teacher is around".
Zheng·I know how to read mind·Zhi Yong: "There is an invigilator for the exam, just get used to it." He looked at the empty white paper, and said again: "Are there any difficulties?"
Tian Zhengguo drew the geometric figure with a look of embarrassment, and then drew the coordinate system. On this point, he did not make any mistakes.
"According to the existing information, which vectors on the plane can be obtained?" Zheng Zhiyong simply pressed his right hand on Tian Zhengguo's left shoulder, further reminding.
Tanaka: ...
The students in "idol cram school" are all scumbags, but they are closer to this in terms of positioning. The girl is Zhou Jieqiong who "language is a big problem and I can't help it", and the boy is Tian Jungkook who "people always have some shortcomings". In the past, fans of BTS had the meme of "four points in English", and the psychological pressure of the program group to take him out is undoubtedly much less.The setting of Tian’s surname is that those who are determined to win or lose must do it, so they can memorize proficiently when it comes to memorizing. Skills, as for things that involve understanding, are much worse. If Zheng Zhiyong makes a slight turn, a hundred thousand whys will pop up in Tian Zhengguo's head.
He is the one who gets sleepy listening to solid geometry, and it feels quite appropriate.
Zheng Zhiyong did not make any comments on Tian Jungkook's silence and embarrassment. He took out the ballpoint pen hanging in his shirt breast pocket, and wrote down the solution process on Tian Jungkook's draft paper, leaving a gentle and focused profile for the camera. It was recorded together with Tian Zhengguo's depression and unwillingness.
Then he went back to the front and continued talking as usual.
"Thanks for your hard work everyone", when the class time is over and the people in front of the camera say goodbye to each other formally, it will be the story after class, "Is today's content too difficult?"
"It's not bad", Zheng Yushuo didn't talk too much. As one of the freshmen who came to shoot the show before his debut, he showed an image of studying diligently. A little more confidence."
"Confidence in passing the college entrance examination?"
"Ah."
"You guys are really straightforward." Zheng Zhiyong said.
Huang Enfei: "It is difficult for us to make great achievements in majors other than art." So the results of cultural subjects...
"It's good not to be ignorant in terms of common sense." Sun Zhouyan said with a slightly better eloquence.
"That's right, I hope that in November, everyone can be admitted to the ideal university, and when they come back, they can introduce to me the experience of studying art majors." Zheng Zhiyong sincerely wished, and at the same time sighed, "The path stretches endlessly. At the end, I am afraid that it will be difficult for me to return, and if I walk on one road, I will not be able to see the scenery on the other side of the road.”
Zheng Zaixuan: "Teacher."
"Ok?"
"Even if the teacher is in SM, I'm afraid I still have to study language," he said, "The company will think that kind of education is more attractive. If you agree with your parents..." Parents are definitely more willing to let their children study that even if they don't become an artist, they can find a job. Professional, not showbiz.
Zheng Zhiyong sighed: "Can't you let me drop a book bag?" It wasn't that he suddenly became poetic, but he just remembered "The Road Not Taken", one of the must-read foreign language articles.
Kim Mingyu has not yet recovered from the state of physical and mental exhaustion from doing the questions in class: "The teacher has dropped a lot of questions."
Will I become a question bank that keeps spraying formulas outside when the show is in the later stage? "I remember it when I see it a lot. Teachers with two years of work experience can almost do it. Although I don't have that much experience, my memory is not bad." At this level of chatting, it's time to say something serious, "You guys I have too little time, for this, my previous considerations were not comprehensive enough, it is good to try my best, and if you encounter difficulties that you really can’t overcome, don’t force yourself too much.”
If you are not at the level of a master student, facing the exam, you have to do two things, try hard when you should work hard, and give up when you should give up-the former has to overcome laziness and laziness, and the latter has to overcome unwillingness and persistence.
Neither is easy.
Zheng Zhiyong originally just faced the students casually, but when he said this, his eyes focused on Tian Zhengguo for a short time, stayed, and then everything went on as usual.
But the atmosphere around Tian Jungkook was still heavy.
"The second time, thanks for your hard work."
This time, I was speaking to everyone. In the past, when they were talking, for a sense of so-called "realism", the camera was still on while the others were packing up. Now that the camera is turned off, the recording of the show is truly over.
Everyone really breathed a sigh of relief, but they are all people who have lived in front of people for a long time, and they will not change their faces as soon as the camera is turned off.There is a reason why Zheng Zhiyong pulled his face down immediately after he finished his hard work politely. His hands were pressing on his temples.
"Are you uncomfortable, thinker?" Min Yalin asked.
"My head hurts a little, maybe it's because I'm bored, or I haven't been exercising recently," Zheng Zhiyong said with a wry smile, "If it doesn't get better next time or it gets worse? Is there any new material?"
"Students can only go to self-study when the teacher is sick?" pd was noncommittal to Zheng Zhiyong's proposal, "Let's get better, thinker".
"I can't do it anymore and there are still questions, otherwise I will take the exam?"
Maybe it was because of the deterrence of the exam, or maybe Zheng Zhiyong's popularity was not bad. When Zheng Zhiyong went out, the students cared about his physical condition one by one. Zheng Zhiyong's response to this was:
"You should pay more attention to your own progress."
Although he does not look very healthy, it is not so easy to fall down.Instead, worry more about yourself, kids.
Especially Tanaka.
"You will have to work harder next time," Zheng Zhiyong said to him privately, "Don't force yourself too much. In the end, there will be no problem to overcome. It is also a realistic ecology."Seeing that Tian Jungkook was really tired, he was inevitably a little worried.
Tian Jungkook shook his head: "Fans all know that the youngest member of BTS is not very good at studying, and they all know what he is going to do, and he must do it in the end."
"Set it up." Zheng Zhiyong, whose head was getting more and more painful, sighed helplessly.
