Sometimes, Ben Gongzi will also teach the students himself, after all, my profession is to be a teacher, even in the Tang Dynasty for so many years, this skill of eating has never been pulled down. Just like today, I went to the building of the Department of Mathematics to explain the binary equations.

It is really quite rewarding to give a lecture in this classroom, which can accommodate 350 people, but in fact it is not less than 500 people, after all, the dean of the college himself teaches the class, which is also a rare opportunity for these students, not only to observe their idols up close, but also to listen to the idols to solve their doubts and teach themselves, which is quite an honorable thing.

And in addition to them, all the math teachers also sat in the front row, quietly taking notes, and they all knew that this was a rare opportunity to observe the teaching of my master of the Tang Dynasty.

He patted the lime and clay-fired chalk ash in his hand, nodded to the full crowd of students and smiled: "Okay, that's all for today's lesson, but I remind you that you need to pay attention to the problems when solving binary equations." First, flexibly select appropriate methods to solve the problem, such as substitution elimination method, addition and subtraction elimination method, etc.; Second, be careful, patient, and make appropriate use of what you have learned, such as fractional equations. Of course, I hope that you will not forget, you can't rush the questions and think that everything is fine, and you should pay attention to the test...... In the next class, I will explain the co-ordination method to all students in another class, and those who are willing to listen can go directly, and I, the dean, cannot rely on my position and not leave. ”

As I spoke, there was a classmate who was standing at the back of the lecture and had raised his hand for a while, because there were too many people, and I finally found out. Do you have any comments to share?

"Students just want to ask what is the overall planning method, and is it useful to learn that thing?" The student's face was curious, it seemed that this little guy still didn't understand the problem of boiling water before making tea. However, the teachers and students present were all fresh and seemed to want my answer.

------------------------------------------------ I smiled, stopped putting away the teaching materials on the podium, and said slowly: "This co-ordination method is actually a closely related to our lives, in fact, it is in your body, and you can encounter it at any time in your life, I will give you the simplest example, you got up late this morning and had to rush to class, but you have to have a cup of morning tea, Then there are a few things in front of you, and the situation at that time is: there is no boiling water; The kettle should be washed, and the teapot and cup should be washed; But fortunately, the fire was lit and the tea was also available. What do you do to get to the classroom with a cup of tea in the shortest possible time? ”

The student who had just asked a question for himself was dumbfounded on the spot, blinking his eyes for a long time before he spoke: "Teacher, this seems to be related to the co-ordination method?" ”

I nodded, "Exactly." The student squinted his eyes and thought for a while, then said with a smile: "If the student wants to arrive at the class in the shortest time, he must first wash the kettle to boil the water, and then wash the teacup and teapot, and after the water is boiled, he can brew the tea directly." ”

"Yes, it seems that you also know the tricks of co-ordination!" I applauded and praised the student very sincerely, but the student still looked puzzled: "Master, this is the method of co-ordination?" ”

I nodded and smiled: "That's right, it is this reason, the meaning of the overall planning method is to change the original inherent service format and optimize the efficiency of work through reorganization, disruption, optimization and other means." Whether you are in your daily life or in your future work, you will use it, I will give you a simple example here, just like when I first built Dianjiang Academy, the first thing to build was the dormitory, why? ……”

In fact, a lot of knowledge, people often use it inadvertently, however, people often form a potential vague consciousness, it is difficult to notice the truth of some things, for example, people eat an apple still owes a little, eat two apples will be full, eat three apples will be supported, then, his consciousness will appear three abstract concepts, and then through the example of three apples, so that his intelligence will make a leap.

It is through such a series of teaching of numbers, shapes and their interrelationships that mathematics not only teaches students knowledge, but also promotes their intellectual development and exercises their logical thinking. Therefore, education is not just about imparting knowledge, but also about promoting the development of their minds and intellects, so that they are better than the blue. This is the purpose and philosophy of education.

The atmosphere of learning is quite harmonious and enthusiastic, and the students seem to have been affected by the forum of Qujiang Academy for a long time, as long as they can't figure it out, they will start arguing, and they all want to rely on their own talents to argue each other, or hope to prove each other's mistakes with facts, so when Ben Gongzi passed by another class, he heard the angry quarrel of two classmates.

It seems to be a heated discussion about the argument in Aristotle's "Physics" that the falling object is heavier than the lighter and the faster it falls, which should be something that the teachers have not yet taught, and it is really gratifying to see the students spitting and spitting over the red faces, and often the truth is born in the controversy, and I look at these two students with a smile and a lesson plan, thinking about whether to appear in front of them now and give them the right answer.

And next to him, a shameless and despicable student was instigating these two to set an example and experiment for themselves, "It's not easy, you two are fat and thin, jump down from the second floor, I'll see if you land together, don't you know?" ”

The two of them didn't know whether they were in a hurry or thought they had practiced light skills, so they rolled up their sleeves and made a gesture to go out: "Jump and jump, who is afraid of whom." ”

No way! Hearing this, Lao Tzu was so frightened that he almost hit his head on the porch. The voice of the instigator is too familiar, who else can there be but Li Yesi, a wicked beast who is tired of teaching? But what made me angry, the seven orifices were about to smoke, strode into the classroom, and shouted at the two Xiaobai who were about to step out: "Stop me!" ”

These two surprised me with the murderous expression and the angry tone of the college dean who suddenly popped up, and quickly stood up straight, for fear of annoying me.

Sure enough, Li Yesi was lying on the desk, with an expression of schadenfreude, hoping to see a wonderful performance. Suddenly, when I crashed in, the guy shrank his head and seemed to want to hide under the desk, and I walked up to him in two big strides and slipped the little kid out. "Give me a good stand!" I widened my eyes and yelled at the guy viciously.

------------------------------------------------ "Hehe, the student heir has met the dean. Li Yesi grimaced and squeezed out an ugly smile and said to me. I sneered: "Long skills? Do you want to jump from here, well, it's not too high, do you want to help you for the teacher, want to see for the teacher, you fall fast? It's better to hurry up for this lesson plan in the teacher's hand. ”

"You don't have to try, it's the students who fall fast, and it must be the students who fall fast." When Li Yesi heard what I said, his little face suddenly turned pale, and he hurriedly smiled.

"Humph!" I glared at the guy again, turned my face, and the two spitting students had regained some of their senses and saluted me. "What are you two doing? Isn't it panicked when you're full? It's really fat and thin, do you feel uncomfortable with your own itchy skin, and you want to jump off the second floor to relieve your fatigue? I glared at the two guys and snorted.

The two of them looked at each other, blushed, and quickly confessed their mistake to me, saying that they had just been carried away by their dedication and enthusiasm for science, and they would definitely not do such stupid things. I sighed: "You still know how to blush, do you know that jumping from here, with your little body, not to mention crippled, I am afraid that you will not even be able to save your life, for the sake of science, we can discuss, we can argue, and even experiment, but do you think that if you practice it with your own life, the truth will be on your side?" This is not called wisdom, this is not called wisdom, this is called stupidity, and you, come back to me! I pointed with my hand, and Li Yesi, who was secretly trying to slip away, walked back with a bitter face and stood next to me begging for mercy.

"Send me a check, write down what you have done, and then, write down your own thoughts about why you have the way you do, remember, if you dare to give me a sloppy look, I will let you go to the confinement room for a while, when you know what is right or wrong, and when you come out again." I said coldly to Li Yesi with a straight face.

This guy nodded bitterly and promised me that he would never do this kind of again. For the other two, I simply taught them to experiment with other methods, such as a round wooden ball and an iron ball, and when you let go from the roof of the teaching building at the same time, you can observe whether two objects of different weights land at the same speed or one fast and one slow.
