Chapter 423 Let your students see what is called the ocean of knowledge
Under Su Jiang's arrogant behavior, all the teachers felt a little ashamed.
I feel like, if nothing else, just this operation, people like me can no longer remember it.
Moreover, what Su Jiang wrote was not only about differential manifolds, but also what was mentioned in the ppt just now.
Therefore, Sujiang had no time to prepare in advance.
It must be something imprinted on his mind.
In the classroom, there were some whispers just now, but now they became quiet.
Especially the older teachers.
They all have mouths opened wide and eyes protruding.
Looking at Su Jiang stupidly.ъìqυgΕtv.℃ǒΜ
I sighed in my heart: I have lived like a dog for so many years?
Su Jiang was on the stage with his back to everyone, and he had no idea what the faces of the people below him were.
After about five minutes passed.
Su Jiang finally finished writing on the blackboard.
Looking back at everyone below, he started talking.
These knowledge points would be different for anyone in any other major, or someone with a poor foundation in mathematics.
There is absolutely no way to understand or understand them.
If you don’t believe it, just take a junior mathematics course in the Department of Mathematics and listen to it. It will definitely be more hypnotic than a lullaby.
But when Su Jiang started talking about it, these knowledge points became easy to understand.
Not to mention the teachers who are somewhat knowledgeable, even the scumbags in the classroom.
At this time, a look of surprise appeared on his face.
There were even some students who even slapped the table in excitement when the first class was over.
"Damn it! So that's what happened! After listening to so many math classes, I finally realized that this knowledge point is like this!"
"Me too, I feel like I didn't understand the previous lessons, but now you're just enlightening me!"
"I deeply understand why when I was in high school, some students said they couldn't understand what the teacher said. It turns out that teachers really have good and bad teachers. Good teachers speak in easy-to-understand terms! Bad teachers speak like that.
Listen to the Book of Heaven!"
"Yes, some teachers like to show off that they know a lot and say things that are simply unacceptable to us. Why bother with such teachers!"
The excited words of the students fell in the ears of the teachers nearby.
It's simply extremely jarring.
A naked slap in the face!
Doesn't this mean that these guys don't teach well in class?
Especially the one who screamed the loudest just now.
The reason why he clamored the loudest was not because he was doing a good job in class.
As a result, I was kicked out halfway through class and listened.
Still listening to a lecture by a freshman who is much younger than myself.
Do you think this would be fun?
But after hearing Su Jiang's extremely skillful writing on the blackboard just now, he had already put away his contempt.
Now the students in my classroom all look and speak as if they have taken the elixir of enlightenment.
His face turned redder.
If you feel so embarrassed, you can dig a hole in the cellar with your toes and shut yourself in.
He even felt that there was already a teacher nearby who was looking at him strangely.
The teacher's name is Kong Dongquan. He is a middle-aged professor about forty years old, and he has studied abroad for many years.
He is the proud disciple of a famous foreign mathematician.
He never imagined that he would be exposed to such a scene at home despite having such a prosperous life abroad.
But his reaction was still very quick.
I immediately found my advantage.
He immediately retorted:
"This Su Jiang may just have a solid foundation in basic knowledge. He has not experienced the more profound world of mathematics, so naturally what he talks about is easier to understand."
"Those of us who have knowledge have seen the broader sky, so we think these things are very simple and basic. Naturally, when we talk about it, it is not as interesting as him."
Several teachers nearby heard him speak.
The trace of embarrassment on his face just now faded away instantly.
That makes sense!
I don’t think it’s just because I think it’s simple, so I speak quickly and in a very general way.
Speaking of which, I still blame myself for being too knowledgeable and unable to take into account the students' feelings.
Kong Dongquan then said:
"The most important thing about learning is not to tell students the basics in detail. By the time they get to university, they need to know that they have studied on their own."
"Moreover, what will they do in the future when they are knowledgeable and no one can teach them things like this?"
"What teachers have to do is to bring students into a new ocean of knowledge. As for how far students can sail, it depends on how much perseverance and study energy the students have."
The teachers on the side nodded in agreement when they heard this.
"Yes, that's it, isn't it? I didn't even think about how to say it just now. In fact, I have always felt this way."
"Yes, studying in college is not an exam-oriented education in high school. It all depends on your own study!"
"This is the way I teach now, opening a door to advanced mathematics for students. Anyone who knows me will be like Dongquan!"
Hua Genghao in front has been writing down Su Jiang's method in his notebook.
This is what Su Jiang said about this knowledge point.
That knowledge point, Su Jiang explained it this way.
I didn't pay any attention to what these guys behind me were talking about.
But Su Jiang on the stage looked at everything below with cold eyes.
Su Jiang heard clearly what Kong Dongquan said just now.
I thought to myself that you, a teacher, can’t teach your students, yet you still make so many excuses for yourself.
Even the ancient city walls are not as thick-skinned as you, right?
Don’t you see that Hua Genghao, as an academician, is taking notes seriously?
I will give you a good feel in a moment, what is strength and what is height.
The second class will start soon.
Su Jiang turned around again and started writing on the blackboard.
Wait until a few minutes pass.
Su Jiang threw the chalk into the chalk trough on the side.
Pat the chalk dust on your hands.
Pull the blackboard up and pull it up.
Let all classmates see it.
Everyone immediately looked up.
At first glance, everyone took a deep breath.
This time it's not a knowledge point, but a question.
The question is very simple, only about two or three lines.
But the students were all confused. They understood every word in the question, but they couldn't even understand it at all, let alone answer it.
"Haha, all my classmates and teachers, this is the question I proposed based on my knowledge of differential manifolds."
"Maybe many students think this knowledge point is just a conceptual knowledge point."
"Actually, this is not the case. The practical significance involved in this knowledge point is still very great, such as this question."
"Of course, this question may be a bit difficult for you, so you can take a look at it first."
Su Jiang looked at the people below and said semi-ridiculously.
This question is the most difficult question in Su Jiang's mind regarding the knowledge of this differential manifold.
He deliberately used this topic to give Kong Dongquan some insights.
What is a true teacher?
"I wonder if the teachers here have any opinions on this question? Is there any way to solve it? How many ways are there to solve it?"
Su Jiang said and turned his attention to Kong Dongquan.
"Then how about I ask you to do this question? Let your students see what the ocean of knowledge is. Let me open my eyes too."
