Chapter 413: First Lesson in College
Monday, 7:40 AM.
The weather is clear and the autumn breeze is cool.
Lu You and three others arrived at the classroom.
The classroom is not big and is a small classroom. At the front are two large blackboards hung side by side on the wall and a podium on the side of the window sill.
Most of the remaining space is occupied by three rows of white tables and chairs arranged in a 1:2:1 ratio. There are spacious aisles between different rows of tables and chairs, which can accommodate two people walking side by side.
At this time, there were not many students in the classroom, only about ten or so, all doing their own things.
Lu You took the three of them to sit in the third row in the middle.
They are here to listen to the class, not to slack off, so they naturally won't sit in the back row, but if they sit too close to the front row they will be facing the teacher directly.
Therefore, the third row became Lu You’s best option.
Zhang Zhichuang unzipped his schoolbag and placed a book with a white cover titled "Linear Algebra" on the table, then took out a notebook with a pen on it.
While taking out his things, Zhang Zhichuang said, "Oh, college is great! Classes start at 8 a.m., so I can sleep until I wake up naturally. It's not like high school, where I get up earlier than chickens and sleep later than dogs. If I'm lazy for a while, I'll be criticized."
Lu You smiled and said nothing.
He is an experienced person and he knows very well that once college starts, the life will be even more stressful than in high school.
Zhang Zhichuang opened the books and notebooks, and saw a lot of words written on the white pages.
At the level of the School of Mathematics at Capital University, it is actually a minority who do not prepare before class.
Especially since the textbooks used in their advanced algebra experimental class are all in English, with a bunch of professional terms, you can't keep up without previewing.
In the next ten minutes, students came in one after another.
They were basically members of the competition training team. Lu You barely remembered them, but couldn't call out their names. To avoid embarrassment, he simply treated them all the same and pretended not to know them.
Unless someone comes over to say hello, Lu You will respond with a polite and courteous smile.
During this time, Lu You's only three acquaintances, the other two members of the imo national team and Qin Xiyue also walked in.
The former reminisced about the past with Lu You and the other three, then went to the back with their roommates, while Qin Xiyue was forcibly held aside by Zhang Zhichuang.
"Xiyue, why are you alone? Where is your roommate?"
Qin Xiyue first said "Good morning" to Lu You and the other two, and then replied: "They were afraid that the exam for the experimental class would be too difficult, so they didn't dare to choose it."
Zhang Zhichuang was delighted.
If Qin Xiyue's roommate doesn't come, doesn't that mean I can sit with her in every advanced algebra class?
Gong Qing frowned, as he found that the information provided by Qin Xiyue was inconsistent with his own understanding.
"Isn't it said that the only difference between the experimental class and the large class is the teaching method, and the exam content remains the same?"
Qin Xiyue explained: "This year, the experimental class has been replaced by the teacher from three years ago. I heard from seniors in the fourth year that this teacher does not follow the usual rules and likes to make up his own questions."
Qin Xiyue pointed to the books on the table and said, "Look, you'll know if you look at the textbooks. My roommates use the ones published by the school, and we use the textbooks from MIT in the 60s."
Gong Qing seemed to be thinking about something, but he didn't take it too seriously.
In his opinion, no matter how things change, the essence remains the same. As long as the exam scope does not exceed the syllabus, he is confident that he can get more than 90% of the score no matter how the teacher sets the questions.
Lu You and Bi Yangde had similar ideas.
For them, exams are not a big deal at all; they are just a means to test their learning outcomes.
"By the way, Xiyue."
Zhang Zhichuang pushed the notebook in front of Qin Xiyue and said earnestly, "I have taken a lot of notes in the past few days. Do you want to check them?"
"Well, thank you."
Qin Xiyue flipped through a few pages of her notebook and asked, "Are you free tonight?"
"Yes! A lot! Very much!"
"Then let's have a meal together, and then find a place to study."
"no problem!"
Listening to the conversation between the two, Bi Yangde slowly clenched his right hand under the table.
Heaven is unfair!
Lu You keenly noticed Bi Yangde's abnormality, patted his shoulder with his right hand, and comforted him: "Calm down, women are not a big deal, they will only affect your speed in solving problems."
"Give me a girlfriend and I'd rather solve the problem slowly!"
……
Eight fifty-five.
A young man wearing a plaid shirt, about 1.7 meters tall, of medium build, walked in with a book and a stainless steel thermos cup in his hands.
The whispers in the classroom disappeared instantly, and all the students looked in the same direction.
The young man had a pair of black-framed glasses on his nose, making him look a little younger.
But the frighteningly high hairline and the slightly bald top of the head inexplicably give people a strong sense of security.
The young man put down the items in his hands, looked around the classroom, and asked, "Is everyone here?"
The classroom was silent and no one responded.
The young man didn't care. He took out his cell phone and opened QQ, then asked, "Does everyone have a cell phone? Those who don't have one, raise your hands so I can see."
The students in the audience looked at each other, but no one raised their hands.
"very good."
The young man nodded and said, "Everyone, take out your phones and open QQ. Let's set up a class group face to face. Students who can't join can ask those around them for help."
Soon, the class group was created.
The number of students in the class increased at a very fast rate until it stopped at the number "51".
"It seems that everyone was very considerate of me in the first class and no one skipped class."
The young man put his phone aside.
"I will post some arrangements for the class group in the group after class. Now let me introduce myself."
The young man picked up a piece of chalk, turned around and wrote two big words and a string of numbers on the blackboard.
"My last name is An Heng. This is my phone number and WeChat ID. Remember this. If you have any math or life questions, you can contact me. However, it is limited to 8 am to 10 pm. For the rest of the time, I will not reply to your messages."
"Teacher An, are you also a psychological counselor?" someone asked curiously.
An Heng turned around, the corners of his mouth slightly raised.
"No, I just want to eat melon."
This simple sentence livened up the originally dull atmosphere and quickly brought teachers and students closer together.
"Back to business."
An Heng clapped his hands, and the noisy classroom returned to silence.
He walked out from behind the podium and came to the aisle inside the classroom, and everyone's eyes followed him.
"Let me ask you a question. Do you know what this class is?"
Zhang Zhichuang immediately raised his hand.
"Student, please speak."
Zhang Zhichuang stood up and replied in an orderly manner: "Advanced algebra."
"What class do you belong to?"
“Experimental class.”
"What's the difference between this and the big class?"
Zhang Zhichuang thought for a moment and said uncertainly: "The teaching method is different from the exam?"
An Heng waved his hand, motioning Zhang Zhichuang to sit down, and asked with a smile: "Student Zhang, what's your name?"
A string of question marks popped up above Zhang Zhichuang's head.
Don't you know my name? Why are you asking?
Although he was puzzled, Zhang Zhichuang still answered truthfully: "Teacher, my name is Zhang Zhichuang."
"Okay, classmate Zhang, I'll remember you and add your regular points later."
Zhang Zhichuang looked surprised. He just wanted to join in the fun but didn't expect to get any benefits out of it.
The atmosphere in the classroom changed again, from a gentle breeze to a turbulent tide.
An Heng turned his gaze back to the whole class and continued, "What Zhang said is not wrong, but it is not correct either, he did not say the whole story.
Just as advanced algebra is not the most 'advanced' algebra and abstract algebra is not the most 'abstract', our experimental class is not about doing experiments.
The purpose of setting up experimental classes in schools can be summed up in four words: teaching students in accordance with their aptitude, similar to the Honors Course in Europe and the United States.
Zhang Zhichuang leaned over to Lu You and asked in a low voice, "Brother Lu, what is the Honors Course that Teacher An mentioned?"
Lu You also lowered his voice and replied: "Just think of it as our top class in high school, providing the best resources to the best students."
“Does Europe and the United States also discriminate against each other?”
Lu You showed a hint of ridicule, he laughed at Zhang Zhichuang for being too childish.
"Europe and the United States are capitalist. They are much more experienced than us in how to maximize profits."
"Fear!"
The private chat between the two did not affect An Heng's free talk.
"Student Zhang mentioned that our teaching method is different from that of the large class. Let me tell you the specific differences."
An Heng walked back to the blackboard and wrote on it with chalk while repeating himself verbally.
“In order to cater to the majority of students, the courses for large classes often start with systems of equations, matrices, determinants, and other content that is closer to the mathematics style of junior high and high schools, and then gradually introduce the concepts of linear space and linear mapping.
Our course focuses on linear spaces and linear mappings. It starts with linear spaces on general fields. Matrices, determinants, and polynomials are all considered as tools for studying linear spaces and linear mappings.
The two methods have their own advantages and disadvantages, and there is no saying that one is superior to the other. The former is easy for most people to accept, but it inevitably misses some essential things. Although the latter is close to the essence, it has certain threshold requirements for students.
In our School of Mathematics, there are indeed a small number of students who have a head start over others, such as those who applied for competitions, those who are born with an abstract physique, or those who have learned linear algebra in junior high and high school. In short, everyone has their own strengths. "
Lu You covered his mouth calmly, he almost couldn't hold back his laughter.
The so-called innate abstract holy body refers to people who are born with strong abstract thinking.
This type of person can absorb abstract language very quickly. When ordinary people are still reading the theorems literally, they have already understood the deep meaning of the laws and even thought of how to apply them.
Lu You has seen a lot of them, and he himself is one of them.
After all, there are few people who can persist in doing scientific research in the field of mathematics that are not abstract.
"So, in order to provide a more suitable platform for this small group of students, the school set up an experimental class."
An Heng threw the half remaining chalk in his hand back into the chalk box, patted the dust off his fingers, turned around and said, "This is the situation. If you have any questions, please raise your hand and ask."
Gong Qing immediately raised his right hand, and waved it left and right twice for fear that An Heng couldn't see it.
An Heng and Gong Qing made eye contact and motioned for him to stand up.
Gong Qing stood up and bowed, saying neither servilely nor arrogantly, "Hello, Teacher An. My name is Gong Qing."
"Hello, Gong-san."
Last year, Ahn Heng was one of the six players who got full marks in the national team of IMO. I have an impression of him.
Including Zhang Zhichuang, Bi Yangde and Lu You who were beside Gong Qing, An Heng all had impressions of them.
Being able to get full marks on IMO means that you can barely be considered to have mathematical talent, and it is worth ANHENG's attention, but it is definitely not something that they value very much.
No matter how famous imo is, it cannot be separated from the essence of solving problems. And in mathematics, solving problems and scientific research are two completely different things.
Those who are good at solving problems may not necessarily be good at scientific research, but those who are successful in scientific research will definitely be good at solving problems.
An Heng has seen too many people who are very good at solving problems but get confused when it comes to writing papers.
Gong Qing didn't know that An Heng had so many psychological activities, so he asked without thinking, "Teacher, I heard that the test papers for the experimental class are different from those for the large class, and you make the questions yourself. Is that true?"
"It's the first day of class and you already want to know the contents of the midterm and final exams? Isn't it too early?" An Heng teased.
"I just want to know whether it is true or not. As for the way the test paper is asked and the specific content, I don't care."
"I'm sorry, I misunderstood. I apologize."
An Heng motioned Gong Qing to sit down, the smile on his face faded, and his expression gradually became serious.
“As everyone is concerned about the exam, I would like to explain here that what Gong said is correct, and I can tell you for sure that the exam is more difficult than the large class.
You don't need to tell me about your previous teacher. The past is the past, and the present is the present. Since the school has chosen me as a teacher, you must follow my rules. If you have any objections, just raise them directly, and I will personally find the school to help you withdraw from the class."
No one spoke for half a minute.
An Heng put on a smiling face again. He still understood the principle of giving a good return after a blow.
"Don't be afraid. Although I said the test paper is difficult, I won't deliberately make it difficult for you. As long as you listen carefully and complete the homework I assign, you will have no problem passing the test, and you will definitely gain more than in a large class."
"I have said all that needs to be said. Let's start the class. Let's open the first chapter, Linear Equations."
