Perhaps it was due to the status between teacher and student. After Xu Yun left his seat, he found that the beating frequency of his heart was rising rapidly, and even his face was getting hot.
No matter how much I adjust, I can never calm down.
But we were halfway there, and we couldn't turn around and go back in front of the whole class.
That's too embarrassing.
For this reason, he had no choice but to bite the bullet and continue walking to the podium, and gave himself an excuse: "It's true that the students sitting next to the window don't even know how to open the window to ventilate the class, which makes it so stuffy."
Su Yushan is less than 30 years old and belongs to a relatively young group among the teachers of No. 3 Middle School. She is more responsible than some teachers with more senior qualifications.
Normally, it is her evening self-study and she will sit in the classroom.
Avoid having to run to the teacher's office when a student has a question and waste time going back and forth.
Speaking of which, this was the first time that Xu Yun took the initiative to ask Su Yushan questions. I remember when they first met each other in the first year of high school, everyone thought that such a young and beautiful female teacher should teach English. Unexpectedly, what she taught was something that gave countless people nightmares. math.
Two and a half years of getting along can be said to be a love-hate relationship.
Soon Xu Yun came to Su Yushan, handed the test paper to the other party, and said respectfully: "Teacher Su, I don't understand this question a little bit. I would like to trouble you to explain it to me."
From such a close distance, one can clearly see Su Yushan's short wavy hair that reaches her neck, as well as the smell of shampoo that penetrates her nose.
Fortunately, it is winter now, so the clothes wrapped around me are relatively thick.
Otherwise, this is not a problem. It is almost like being tortured, and it is a double torture of body and mind.
Just when Xu Yun was trying to control his eyes and focus on the test paper as much as possible, Su Yushan frowned slightly and asked, "Is it another sequence summation problem?"
Hearing this, Xu Yun felt guilty for a while.
After all, Su Yushan had just repeated the question about sequence in the morning, and he obviously didn't listen well when he came to ask it now.
However, there is nothing he can do about it, because he is too far behind the others, and it will be more difficult to calculate when he encounters a slightly more complicated summation problem of a sequence.
Feeling embarrassed, I had to resort to silence.
Fortunately, Su Yushan did not dwell on this point, and then patiently explained: "You can easily calculate the result of this question using the split-term subtraction method I mentioned before. To put it bluntly, it is to turn a multiplication of the denominator into the difference between two equations. , essentially it is the inverse operation of the general divide.”
…
"According to this idea, the solution will be..."
Xu Yun listened carefully to Su Yushan's story, and soon found that he had a very special feeling.
It was as if the formula on the test paper came to life in his mind, and its essential characteristics were quickly extracted. In this extremely clear state of thinking, the difficulties that had previously troubled him were instantly smoothed away.
Even before Su Yushan finished speaking, he thought of the subsequent calculation steps.
If he and Sequence were just strangers who didn't know each other just now, then after listening to Su Yushan's explanation, they can be described as good friends.
The most important thing is that if you encounter the same type of questions in the future, you only need to use your own understanding and summary.
In this way, as long as he keeps asking Su Yushan for various types of questions, I believe that his math scores will soon improve and it will become his best subject.
"Just improving my abstract thinking ability by 15% has such a strong effect. If it increases to 30%, maybe I can look forward to going to a key university."
Feeling the changes in himself, Xu Yun couldn't help but think about his college life.
Then he replied respectfully: "Thank you, Teacher Su, I understand."
"understood?"
"Do you really understand or pretend to understand?" Su Yushan raised her gaze and scrutinized her face.
Being able to be called out to talk to Sun Xueliang several times because of single moves, she naturally knew Xu Yun's actual situation very well. Even if she started to review hard from now on, nothing would change in less than a day.
Originally, she wanted to explain it twice more to ensure that Xu Yun could understand and not to dampen students' enthusiasm for learning.
I didn’t expect the other party to express his understanding so quickly.
This surprised her.
As we all know, many students are thin-skinned. Even if they dare to ask questions, they are embarrassed to ask the teacher to repeat what they said. Most of the time, they will say that they have understood.
In fact, you still have to go through a lot of trouble to get back to your seat, which is a waste of time.
That's why she asked specifically.
It can only be said that Xu Yun's usual performance is not enough to make her trust him.
It's a pity that Xu Yun was immersed in the joy of the effect of abstract thinking ability and did not notice the tone of Su Yushan's words. When he heard the sound, he answered again without even thinking: "Teacher, I really understand."
This time Su Yushan did not ask any more questions, but quickly wrote a question of the same type in her draft book, then threw it to Xu Yun and said: "I want to see if you understand, so I will try to solve this question here. "
At this time, Xu Yun finally reacted and realized that he was being questioned, and couldn't help but smile bitterly in his heart.
However, he didn't refute anything. He just moved a bench from the side and occupied a corner of the table to calculate silently.
After seeing the questions in the draft book, I realized that Su Yushan did not mean to embarrass him.
The type and difficulty level of the entire question are almost the same as the one just explained. If you really understand it, you can basically do it.
Of course, Xu Yun might have been blinded in the past, but after improving his abstract thinking ability, this question was nothing.
Based on my previous summary of the lecture, I quickly calculated the correct result.
"Teacher, I'm done."
"You finished the questions so quickly!?" Su Yushan's face was filled with suspicion when she heard this. She reached out to take the draft book and lowered her gaze to look at it. The next second, she suddenly showed surprise: "There is no problem with the calculation process. It's really true." It's done." He said and quickly picked up the pen to verify.
But after confirming that the answer was correct, his expression seemed a little regretful: "I didn't expect that your understanding of mathematics is quite strong. You have some talent. It's a pity that it has been wasted before."
"I think it's not too late to work hard now." Xu Yun answered confidently.
When Su Yushan heard these words, she was startled for a moment, then raised her gaze to look at Xu Yun slightly surprised, but soon turned into a smile and affirmed: "You are right, it is not too late to work hard now, and we will meet again in the future. If you don’t understand a question, you can always come to the office to see me.”
She could tell that Xu Yun really wanted to work hard. With this spirit and good understanding ability, there was a lot of room for improvement if he made a review plan.
In this case, she certainly wouldn't mind giving him a hand if she could.
You must know that most of the time it is not the teacher who gives up on the students, but the students themselves who cannot hold on.
Facing Su Yushan's help, Xu Yun was grateful from the bottom of his heart. He immediately leaned over and said sincerely: "Thank you, Teacher Su. I will work hard."
