On this day, there is light snow in the 24th solar term.
Although it is called light snow, it actually does not snow. The sun is shining brightly in the sky, and it is still a beautiful sunny day.
Today, Qi Yu wore an elegant robe and went to the official school for formal classes.
Yes, today is his first class after taking up teaching.
As soon as he stepped through the gate of Fu Xue, Qi Yu felt emotional.
I recall that three months ago, I was still a student at the Fu Xue School, but now I am holding the coaching staff and standing on the lecture platform.
Life changes so quickly!
It was so fast that I couldn't react in time.
Jingle bell bell~~~
The time is up, ring the bell for class!
All the students bowed to greet each other and said, "Welcome to you, Mr. Qi."
Qi Yu spread his sleeves and said kindly: "Everyone, please sit down!"
Then, all the students took their seats.
In fact, Qi Yu did some homework before the class started.
However, it is not lesson preparation.
Mainly to get a feel for the current tutorials.
After watching it, I was disappointed.
Those are books, can they be regarded as arithmetic tutorials? Why does it feel like that ancient fossil?
It's so old!
Innovation?
That is inevitable and necessary!
But before that, you still have to figure out your positioning. Although it is innovative, you can't mess around.
In essence, his duty is not to cultivate mathematical geniuses, but to help these students pass the imperial examination. If it weren't for the exam, and you begged them to learn, they wouldn't be willing to learn!
This is called positioning.
In addition, you also need to understand the arithmetic tutorials of this era.
If you are not even familiar with these, how can you talk about innovation?
As far as the current era is concerned, the main tutorial on arithmetic is still "Nine Chapters of Arithmetic". Although this ancient method has some systems, it is too primitive and obscure to understand, and it is difficult to apply it smoothly.
What does that mean?
In layman's terms, it means that this ancient method is not only difficult to understand, but also very poor in practicality.
Let’s talk about it in detail.
Addition and subtraction are relatively simple, and multiplication and division are not difficult. Even if they are encountered in the imperial examination, most of them can be passed. So, these are not the main points.
The most feared thing in the imperial examination is the "overs and under" arithmetic questions, which are a real obstacle. Nine out of ten candidates cannot do it. In their eyes, it is really too difficult.
Think about it, asking these students who don't even have a solid foundation in mathematics to solve equation problems is not asking Wu Dalang to play basketball, forcing others to do something difficult?
Therefore, the focus of my own teaching is to solve this problem.
How to solve the test questions faster, simpler and more intuitively is innovation.
Qiyu created a unique theoretical system based on the actual situation. Then, he pondered and improved it in daily teaching, and finally formed a text tutorial.
Yes, a theoretical textbook "Profit and Loss Has a Solution" written by Qi Yu has come out.
This book was first reviewed by the governor of the government office, then approved by Lord Yu, and finally printed.
Look at the content again.
This book first proposed the concept of 'unknown numbers'. For example, let a certain unknown number be 'A' and a certain unknown number be 'B', and then substitute these unknown numbers into the hypothetical formula for calculation.
Theory is easy to create but difficult to teach.
Qi Yu originally thought that this was an easy-to-understand knowledge point, but later he discovered that most students couldn't really understand it at all.
Alas, studying things to achieve knowledge is easier said than done?
There was no other way, so Qi Yu had no choice but to instill it day by day, until they formed this concept, and then he talked about how to solve it.
…
The deceased is like a man who never gives up day and night.
Time passed like this day by day.
Qi Yu taught and explained carefully and became a hard-working little gardener.
Results are showing day by day.
Until one day, the students were surprised to find that those arithmetic problems that they thought were unsolvable were actually solved by Mr. Qi's unique theory!
In fact, any arithmetic problem about surplus or deficiency can be solved in a very short time as long as you list it correctly. The efficiency is extremely high.
Therefore, Qi Yu became famous in the government school!
And it is well deserved.
At the beginning, those experienced senior eunuchs dismissed his teachings and even sneered at them.
However, after waiting for a while, the old teachers were shocked to find that the students' arithmetic abilities had improved rapidly.
Facts speak louder than words.
In the end, all the old teachers were convinced by the theory of "Profit and Loss Has a Solution", so that later, these old guys also took the initiative to come and sit in on the class.
And the evaluation of Qi Yu's teaching by the government school was unanimously A-grade!
Actually, there is a little regret in it.
Qi Yu feels that the teaching materials can be enriched to better innovate the theory of arithmetic. However, no one is willing to learn this knowledge that has nothing to do with the imperial examination. It seems that at present, this can only be achieved.
This is all based on Lord Yu's full support. If it were other local officials, it is estimated that even these would be difficult to achieve.
In other words, the publication of this book is largely the result of chance.
As everyone knows, this seemingly accidental coincidence has injected a new atmosphere into the current Dafeng Dynasty. Although it is not visible yet, as it continues to spread in the future, it will eventually affect this era. Of course, this is a story for another day.
…
"Mr. Qi, is arithmetic also a type of learning?"
"um, yes!"
"But why do others call it 'art'?"
Qi Yu thought for a while, then took a turn and explained: "This is correct! However, how to make 'art' more practical belongs to the category of knowledge."
"Oh... let me ask you sir again, even in terms of the field of study, is "Profit and Loss Alignment" the top one?"
Qi Yu shook his head decisively and said: "Since ancient times, there has been no first in literature and no second in martial arts. No one can be said to be the top in any knowledge. You must remember that there is no end to learning by studying things to gain knowledge."
"Oh... the students have learned a lesson."
Then, there was a snap!
Qi Yu slapped his ruler and said, "Class is over!"
…
The waves in the sky are easy to fade away, but the heat is hard to stay.
Autumn has come.
This is Qi Yu's second year of teaching at Fu Xue.
During this period, he balanced the teachings with his own study, and his life was comfortable and fulfilling. Within the Fu School, he was gradually promoted from the original Mr. Qi to the Qi Scholar.
Not to mention anything else, as far as his attainments in arithmetic are concerned, he is enough to be called a scholar.
The monthly payment is also pretty good. Liu Quan did the calculations in private and found that after deducting various household expenses, there was still something left over, and the original family wealth was still there.
Qi Yu's career is very stable, and his family is equally gratifying.
At present, Xiaotong's knowledge is getting better and better, and his son Qi Xiao is getting stronger and stronger.
The only thing that is not harmonious is that the relationship between their siblings seems to be a bit unharmonious.
The younger one likes to play behind the older one, but the older one dislikes the younger one and is too lazy to lead him.
Haha~~~
This day, someone knocked on the door.
When I opened the door, I saw that it was the messenger arriving with a message.
Huh?
It’s actually a letter from my old friend Qi Jing!
