Chapter 82 Ah, isn't this the teacher's job?
Wang Bo said, pushing the questions over. These are some physics competition questions assigned by the physics teacher yesterday.
Chen Chu took it over, glanced at it,
Topic 1:
Two cylindrical containers with the same section: the height of the right container is H: the upper end is closed: the upper end of the left container is a piston that can slide without friction in the container...
Chen Chu reviewed the questions quickly, thought for more than ten seconds, and answered quickly.
Solution: Let…
Quickly write down the pen, write out the formula, and solve the problem smoothly.
Wang Bo stared intently at the side, his mouth gradually opened wide.
Chen Chu finally put pen to paper and pushed back the topic, "Do you understand?"
Wang Bo nodded vigorously!
"Will that be done?"
Wang Bo hesitated and shook his head.
Chen Chu shook his head, took the topic, and explained it carefully.
Wang Bo listened carefully, nodded repeatedly, and a look of suddenness gradually appeared on his face.
The situation of the two of them has attracted the attention of some people.
Although it is early self-study, there is no teacher on the podium.
Someone in the front row has been listening, nodding from time to time, listening to it feels a bit scratchy, not enjoyable.
Turned around, sat facing Chen Chu, and listened intently.
The people around gradually gathered some people like him, listening intently.
After one question was finished, Chen Chu asked, "Are you going to do it now?"
Wang Bo nodded vigorously! "It's over!"
Four or five people had already stood beside them, and they also said, "I will too!"
"I understand a little bit, but I didn't hear some places earlier and missed it."
After Wang Bo opened his mouth, someone finally couldn't bear it anymore and brought a paper to cover Wang Bo's question.
"Student, I can't do the last physics competition question, can you show me?"
"Yes, the last question is too difficult, I can't do it either!"
"Me neither, this question is too difficult."
"Hey, aren't you always number one in physics? You can't either?"
"Too hard to..."
"…oh."
"You oh what? Can you do it? Just oh oh!"
Chen Chu picked up the copy test paper with rough typesetting, looked at it, and reviewed the questions.
Chen Chu fumbled with his hand while watching, "Hey, where is my pen?"
Someone quickly handed over a pen, "Classmates, use mine. The gold pen is easy to use."
Chen Chu glanced at it, and wrote a few words on the draft paper. It was not bad, smooth and smooth, and the metal pen tip felt a bit 'soft' to use.
"Thank you." Chen Chu thanked.
Then solve the problem on paper, explaining while solving the problem.
The people around were listening intently, and the self-study was over early if they didn't pay attention.
…
Early self-study is over, and the math teacher arrives in the classroom ten minutes earlier.
When I came to the door of the classroom, I was shocked.
Because Chen Chu was standing on the podium, there were dense formulas and steps on the blackboard.
At this time, Chen Chu was talking about a math problem.
The math teacher stepped lightly, made a shush gesture to some students who noticed him, sat on the empty seat under the stage, and watched quietly.
The teacher looked at the formulas and problem-solving ideas on the blackboard, and gradually opened his mouth...
A train of thought that has never been imagined, and a slanted way of solving problems, ah, this, this, this...a genius.
“…key information…list out the formula…substitute in…
Do you understand? ", Chen Chu turned around, dropped the chalk, and supported the podium with both hands.
"understood!"
"understood."
"Um, I don't understand."
Chen Chu scratched his chin, picked up the chalk again, "Okay, tell me again."
"Students who understand, I will write a question of the same type, and you can do it to deepen your impression."
Chen Chu didn't notice that there was someone sitting in his new seat, so he just glanced over and basically didn't recognize him.
They were all new faces, and a teacher sneaked in, but he didn't notice.
Then, continue to explain.
The school bell rang suddenly!
Chen Chu dropped the chalk, picked up the blackboard eraser and quickly wiped the blackboard clean.
It was too late for the math teacher in the audience to stop it, and they had already wiped some.
"Student Chen Chu! Wait!", he hastily called out.
Chen Chu was taken aback. This was obviously not the student's voice, but the teacher's?
Chen Chu glanced at the door of the classroom, no one?
Laughter came and went in the classroom, and all the students laughed.
Someone reminded, "Student Chen Chu, the teacher is in your seat!"
Chen Chu found his seat, and found his new teacher in his new seat.
If he hadn't had a good memory, he might have forgotten his new seat.
Chen Chu smiled awkwardly, "Hello, teacher! Come on, I return your seat!"
Chen Chu knew this teacher.
Last week when he was doing the college entrance examination papers in the office of the director of the school affairs office, he was also present, and he was also the teacher who was responsible for correcting the math papers.
The math teacher stood up and waved his hands, "You continue to speak, you are very good."
Chen Chu was stunned for a moment, "Teacher, but I'm a student?
Isn't that appropriate? "
Teacher, this is your job, hello!
The math teacher waved his hand, "If there is anything inappropriate, just tell me. If there is any mistake, I will correct it."
Chen Chu opened his mouth, and finally he could only say, "Okay..."
He turned around and wiped the blackboard clean, and continued on to the next question.
The math teacher took it very seriously at first, thinking that he could correct Chen Chu's mistakes.
But the more he watched him later, the more he doubted himself. There was not a single mistake in the topic Chen Chu talked about.
And the problem-solving method is easy to use, and the thinking is novel and ingenious. Although the thinking is a bit caught off guard, it is very easy to use.
Well, very very easy to use.
This point can be known by looking at the expressions of those students who suddenly realized.
In the past when he gave lectures, these students were not so easy to accept new knowledge.
The math teacher gradually became ignorant and began to doubt his teaching ability.
Is my teaching method no better than a student?
No, this is not just a gap in teaching methods, but also a generational difference in problem-solving methods.
The math teacher bowed his head silently, and wrote down Chen Chu's problem-solving method on his lesson plan.
Copy it, copy it, it won’t be used this time, but it will definitely be used in the next one!
This problem-solving method is easy to use!
～
Finally get out of class was over, and Chen Chu's throat was a little hoarse when he spoke.
He's been cuing the new math teacher with his eyes, expecting him to catch his eagerness and give him his megaphone.
Unfortunately, the math teacher didn't understand his earnest gaze at all.
He thought Chen Chu was asking whether his topic was right or wrong!
Nodding affirmatively all the time, yes, you are right, great!
Chen Chu: "..."
Why are you nodding, give me the megaphone, my voice is hoarse.
In the end, the math teacher didn't understand what Chen Chu meant, so he gave him the megaphone.
But Chen Chu can't use it anymore, because get out of class is over.
Chen Chu immediately put down the chalk, and under the puzzled eyes of the math teacher, trotted up to him, picked up the water glass on his desk and filled it with tons.
Spring water, quench your thirst.
Chen Chu of Niuyin made the math teacher suddenly understand something.
He felt a little guilty, patted Chen Chu on the shoulder, and walked away quickly.
Chen Chu sighed. Fortunately, the effect of the spring water was very strong, and the hoarseness of his throat was completely cured.
～
Time flies by.
In the next two days, all Chen Chu did was study and study (fishing and fishing).
The most frustrating thing is that there are no weekends in the third year of high school...
Yes, there are no weekends in the third year of high school, and there is still one month before the college entrance examination.
The whole third year of high school was sprinting like crazy.
