Chapter 64 Technology is the real huge profit
“Actually, I think chemistry is really interesting.”
Xu Qingshan said to Ye Xincheng while holding the comprehensive science paper for the half-month exam.
"Go away, I don't want to talk to you."
Ye Xincheng was listless.
He now seriously doubts that Xu Qingshan will absorb other people's luck, absorb other people's expertise, and then make progress through malicious competition.
What a hateful man!
“What are you doing?”
"Isn't it just that chemistry is one point lower than mine?"
Xu Qingshan put down the paper and put his arms around Ye Xincheng's neck.
"Is that a matter of one point?"
Ye Xincheng looked desperate.
"There has been an insurmountable barrier between you and me, brothers."
This is a half-month exam.
Xu Qingshan once again proved that his success was no accident with a total score of 658 and 24th place in his grade. He even still maintained a high upward trend.
Xu Qingshan himself has been thinking about learning since his return. Later, after discussing with Ye Xincheng the key to improving chemistry, he finally began to look for the joy of learning.
Xu Qingshan relied on organizing knowledge points to lay a solid foundation, and relied on a large number of questions to improve his scores.
The so-called fun of learning at that time was actually just the pleasure of improving the final score during the settlement stage of each exam, not the fun of learning itself.
But after passing the stage of urgent need to change his family and social status.
Xu Qingshan can no longer rely on simply answering questions.
The basic question bank is currently of little use to him.
He began to explore the joy of the subject.
It's okay if you don't dig. Once you dig, Xu Qingshan understands what true understanding is.
Thinking driven by a combination of interest and subjective initiative is many times more efficient than purely for scoring.
"But how did Shan'erqi achieve such rapid improvement in such a short period of time? Even if I saw the framework and ideas you listed that day, no matter how fast you organize them, you still have to have time to understand them, right?"
Ye Xincheng was very confused.
He put Xu Qingshan's science papers together with his own, and took out the ones from the last monthly exam.
Although the difficulty of the comprehensive science test in this half-month test is much easier than last time, is this not the reason why Xu Qingshan took the chemistry test from 80 to 99 in one go?
From the content of the answers on the paper, it is actually easy to tell whether a student's performance is good on the spot or whether he understands the test well.
Xu Qingshan's comprehensive science paper has accurate answers, precise points, detailed reasons, clear calculations, and no redundant steps in his thinking.
It can be seen that he has thoroughly studied high school chemistry.
"Isn't that why my brother Cheng taught me well? That's why I'm progressing so fast."
"Stop talking. The more you say this, the more depressed I become. I didn't teach you my method at all, and you realized it."
Ye Xincheng was even more depressed.
But he was depressed, and he also wanted to know Xu Qingshan's secret.
There is no utilitarianism, Ye Xincheng is purely passionate about chemistry.
"Actually, I was too good at rote memorization, and I improved my breadth by answering basic questions."
Xu Qingshan explained.
"Now I am constructing core concepts and connecting the previously isolated knowledge points in one go. All knowledge is active in my head like atoms and molecules."
Xu Qingshan randomly found a homework sheet and planned to share his thoughts with Ye Xincheng in a more systematic way.
"The core concept is actually the elements of the periodic table of elements we mentioned before. I understand them to have three characteristics."
“First, coreness, which occupies the core position of the knowledge network and is the key bridge to establish connections between small concepts. It is like a knowledge tree. Without the core, isolated knowledge points can only become fallen leaves and be forgotten. ”
"Second, abstraction is actually about tracing back to its origin and summarizing the general characteristics of the entire system. It is the essential connection of knowledge."
"Third, transferability. Core concepts explain the essence of things. The simulation experiments you mentioned can be transferred in different real situations. They can solve our subject problems and solve some similar homogeneous problems in life."
What Xu Qingshan said is actually not innovation. He just summarized Ye Xincheng's methods into a more systematic system.
"And we also need to distinguish between concepts and terminology. Teacher Bai Qi sometimes gets confused when giving lectures."
"Terms such as acid, amount of substance, chemical equilibrium constant number, and hydrolysis of salts, do we often treat them as concepts when the teacher talks about them?"
"But if we only repeat the appearance and ignore the meaning, we will confuse the concepts. Just like when we occasionally make mistakes in answering questions, we will write ionization as electrolysis, and the conservation of electrons as the conservation of charge. These are all normal. Sometimes the exam teacher does not notice it and gives points. , but the college entrance examination cannot provide it. Even if the college entrance examination does, will the real physical world provide it? "
Xu Qingshan fully demonstrated his system concept.
Ye Xincheng fell into deep thought.
He knew how to do it, but he lacked scientific guidance.
His chemistry is the foundation laid by years of love and study.
Ye Xincheng originally thought that his occasional problems in exams were due to carelessness.
But now it seems that may not necessarily be the case.
"When I understood the entire Pugao chemistry system, I expressed the chemical concepts I understood in complete sentences, removing professional terms and multiple concepts, and expressed them in the most authentic statements. Just like..."
"All matter in the universe is made of tiny particles."
"It's a combination of cognitive concepts and existing experience."
"Then I discovered that [particles] refer to each other in general, and problems will arise. When problems are discovered and raised, interest, love and innovation will emerge."
“So, the core of macro cognition, micro explanation of reasons, and expansion of lower concepts constitute my impregnable subject system.”
Xu Qingshan has written a complete cognitive system on paper.
This is how he finds joy in chemistry these days.
"If we really want to define the subject of chemistry, then I think"
"Chemistry is a basic discipline that studies the composition, structure, properties, transformation and application of matter at the atomic and molecular levels. It is characterized by understanding matter from a microscopic level, describing matter in symbolic form, and creating matter at different levels."
"Explains the research objects, research content, research perspectives and chemical substance characterization methods, as well as the value of this subject."
Ye Xincheng suddenly felt that Xu Qingshan was born with a focus and enthusiasm for the origin of science.
Much like when he was a child, he saw his grandfather taking the materials he brought home for titration testing, and saw the slow discoloration process of the materials, which aroused his interest in chemical materials.
It is derived from human beings’ most primitive desire to explore and seek knowledge about knowledge, nature, and science.
And a strong desire for control and power in an attempt to control the world.
Ye Xincheng suddenly felt that Xu Qingshan's rapid improvement in chemistry results was not so exaggerated.
To use an analogy.
Xu Qingshan used to memorize chemical formulas, memorize knowledge points, and review question banks, just like practicing martial arts routines.
He has tricks, which are three-point effective against the enemy, but he relies solely on his posture to support them.
But it's different now.
If he clearly understands and explores the essence of chemistry as a subject in high school, finds the joy of learning and exploring, and builds his own core knowledge system, then he is a master of internal skills.
Xu Qingshan's strong internal strength and solid and rich martial arts routines make him invincible in the application of practical knowledge and in the examination room.
To use a less appropriate, less mature idea.
If Xu Qingshan wants to drop out of school now.
In the Golden Triangle of Southeast Asia, there will definitely be a top-notch technical super fan, and the things he makes will probably be frighteningly pure.
Changing careers can cause harm to the world.
Xu Qingshan only feels that he is terrifyingly strong now.
Of course, just think about it.
He promised to follow the right path in this life, and the material market in the future is so vast, Xu Qingshan doesn't think that engaging in high-tech will be worse than being a fan.
Technology is the real huge profit!
