Xueba's Sea of ​​Stars

Chapter 13 Liu's Note-taking Method

The National Day holiday is fleeting for senior high school students, and many students return to school without even having time to watch the news broadcast.

As the class teacher Chen Fang said, the monthly exam will be held on the second day after the National Day, so teachers and students in today's class are making the final sprint for this exam.

During the lunch break, Wu Bin came to the teacher's office with an exaggerated stack of papers, each of which represented the "love" of the two teachers of physics and mathematics for him

Cai Guoping took Wu Bin's physical paper and began to read it very quickly, which meant that there was no mistake in Wu Bin's paper.

"Huh? Why are these few sheets empty?" After flipping through about seven or eight papers, Cai Guoping pointed to a completely blank paper and looked at Wu Bin.

"Oh..." Wu Bin touched his nose, not knowing what to say.

"What the hell, just say it directly, I believe it's definitely not because you didn't have time to do this kind of reason."

"Because I think...the repetition rate of question types is too high. I don't think it will improve me if I repeat these types of questions, so I save time." Wu Bin was a little cautious when he said it, fearing that Cai Guoping would think that he Look down on physics.

But this time, after hearing Wu Bin's words, Cai Guoping not only did not get angry, but laughed and said: "Okay, okay, it's very good that you can realize this. It means that you have jumped out of the level of studying for the sake of learning and studying for the exam."

Hearing Cai Guoping's affirmative words, Wu Bin breathed a sigh of relief. In fact, the reason is very simple. After completely mastering a kind of knowledge, low-level repetition is not a good thing. For example, for problems like chickens and rabbits in the same cage, relying on simple Addition and subtraction can be confusing, but once you master the advanced equations, you can solve them easily.

That is to say, looking down from a higher level, many problems will naturally disappear.

But at this moment, Cai Guoping suddenly took out a pen from the pen holder and added: "But if you make mistakes in the types of questions on these papers in the future, be prepared to give me questions until this pen runs out of oil."

"Okay, no problem." Wu Bin nodded confidently.

In physics, Wu Bin not only mastered the knowledge given to him by high school books, but also learned a lot of difficult courses from the system, which enriched his knowledge base.

Coupled with his extensive study to make the foundation absolutely solid, all the exercises given by Cai Guoping can be memorized back and forth.

This accumulation of knowledge gave him enough self-confidence.

"Then I have nothing to do with you, go ahead." Cai Guoping waved his hand to Wu Bin.

When it comes to mathematics, Wu Bin is not so confident. Although he has finished all the papers given to him by Liu Yushan, there are a few questions that are not sure whether they are correct, which forms a strong contrast with the boring physics.

This made him can't help feeling that the physics learning talent bonus obtained in the previous lottery has a great effect on the consolidation of the foundation and the overcoming of difficult problems.

After patiently correcting all of Wu Bin's papers, Liu Yushan scratched his head, stretched out his right hand and beckoned to Wu Bin, motioning him to come closer.

Although Wu Bin was a little strange, he still leaned forward slightly and got close to Liu Yushan.

"You think physics is easier than math?"

Liu Yushan said this very quietly.

"Yes." Wu Bin replied straightforwardly.

"It doesn't make sense..."

Liu Yushan turned out a paper with emotion, pointed to a parabola and said, "This question is a dead end by using Weider's theorem, but it can be solved by the unified second equation of the conic section."

Wu Bin glanced at the question, thought for a while, nodded and said: "No wonder, I said why the calculation of this question is so heavy."

"I don't blame you, I haven't explained this kind of problem to you carefully, and I didn't expect you to be able to do it."

In addition to this parabola problem, Wu Bin made a lot of mistakes, the first one being trigonometric functions.

The graphic nature of trigonometric functions, coordinate operations of vectors, inductive formulas, etc., all made him feel like he had hit the ceiling. To put it simply, he couldn’t grasp the essence, so every time he encountered a trigonometric function problem, he had to bite the bullet and do it.

The other is assembly. After learning about the bottleneck, Wu Bin understood why assembly appeared in the first unit of the first year of high school, because it runs through the entire high school and occupies a very important position.Parity, monotony and periodicity consumed his brain cells in large quantities for a long time.

As a result, after hours of math problems, he has to do physics problems for a while to relax.

Otherwise, even a person like him who knows how to overcome difficulties can't hold on, just bite the steel plate with his teeth!
After spending a lunch break in the office, in addition to covering all the math papers, Liu Yushan taught him the powerful functions of Casio calculator. Although it was not powerful enough to improve Wu Bin's problem-solving ability, it could indeed save him money. It saves a lot of time on complex calculations, and it can be regarded as a powerful tool for solving problems.

Back in the classroom, Wu Bin continued to do math problems, his heart was full of dissatisfaction, his goal was to step down the math class representative next door!
When it was time for evening self-study, Wu Bin discovered that Liu Yushan had changed classes with Zhou Wenxiang, the Chinese teacher who was supposed to be on duty. Naturally, the reason was to tutor him in mathematics.

When Cai Guoping heard in the office that Wu Bin had basically mastered high school physics, the fire in his heart that had not been ignited for a long time, which belonged to the fire of competitiveness, suddenly burned blazingly!
Wu Bin was a little flattered by Liu Yushan's enthusiasm, but of course he was still happy to accept it.

When Liu Yushan started lecturing himself, Wu Bin immediately noticed that this seemed to be different from his usual lecturing ideas, but he didn't pay much attention to it until the evening self-study was about to end, and doing the last paper suddenly made him feel like himself. I felt enlightened and had a long-lost sense of pleasure when I started doing the questions.

"Ms. Liu, you are amazing! I feel that my ability to do all the questions has been upgraded now."

In the end, Wu Bin, who made a perfect paper, wanted to hold Liu Yushan in his arms and kiss him.

To put it simply, the method Liu Yushan told him was to dismember a question into pieces when doing examples or analyzing wrong questions. He wished he could find out all its conclusions under one condition, and then summarize it in one place every time he encountered it. After two times, you will naturally know which conclusion each condition requires in this question.

Seeing Wu Bin's progress, Liu Yushan was naturally also very happy. He also thought about this method all afternoon, and felt that it might be suitable for Wu Bin, so he couldn't wait to exchange the evening self-study.

"Actually, this is the Cornell note-taking method. I improved it a little bit." Liu Yushan said with a smile.

"Awesome, then should this be called Liu's note-taking method?"

"As long as it works for you." Liu Yushan said, looking at his watch, "Okay, go back to sleep, it's getting late, and you have an exam tomorrow."

"Okay, thank you Teacher Liu."

After Wu Bin finished speaking, he bowed deeply to Liu Yushan. This teacher really put a lot of thought into him.
