Of course, it wasn't just the students of Grade 12 Class 3 who were waiting…
In the corner of the last row of Class 3, the math teacher of Class 3, Zhang Bo, was also filled with curiosity as he waited for the live broadcast to begin…
As a top student who graduated from Nankai University and a math teacher who had taught at Sun City No.1 Middle School for decades, Zhang Bo did not believe in miracles, nor did he believe in inexplicable leaps and bounds. He believed in hard work.
Therefore, he felt that it was inappropriate for him to stand here.
but... His student, Liu Yanyan, had improved her math score by 50 points in a short period of time, which really piqued his curiosity.
He wanted to know…What kind of educational streamer had such ability? Or perhaps he wanted to know the real reason why Liu Yanyan's grades had improved so much.
"It's starting, it's starting!"
Suddenly, a student raised his phone and shouted.
Instantly, the entire Grade 12 Class 3 fell silent.
All the students looked at the projection screen on the podium, and a scene appeared on the screen.
What greeted his eyes was a 'light yellow' wooden desk. On top of the desk was a mock college entrance examination paper, a draft paper, and a black pen. It was simple but concise.
"Hello to all the students of Grade 12 Class 3 of Sun City No.1 Middle School.”
" Welcome to the learning stream."
"Let's begin the lesson."
Without any unnecessary nonsense, after a simple opening speech, Gu Bai began teaching.
Liu Yanyan had sent a message to Gu Bai before the livestream. This time, Class 3 was watching the livestream on the big screen, so Gu Bai didn't care about the number of people in the livestream.
Anyway, as long as the students of Class 3 could understand the mathematics knowledge he taught, the system would reward them.
"Set M={2,4,6,8,10}, N={x|-1x6}, then M Empyrean N=()"
“A.{2,4}B.{2,4,6}C.{2,4,6,8}D.{2,4,6,8,10}”
"Assembly is one of the compulsory questions in the college entrance examination. If you want to master the concept of assembly, you must immediately assemble, such as set, intersection, union, and complement."
Just like that, Gu Bai began teaching according to the order of the test papers.
Since he was facing the entire group, Gu Bai would explain it to them regardless of whether it was simple or not.
Very quickly.
After the topic selection, some students with good grades in the class said,
"It's just so-so. It feels similar to what our math teacher said.”
"Yeah, nothing special."
"Sigh! The greater the expectations, the greater the disappointment."
After all, these questions were very easy for these students with good grades. They already knew them.
However, the eyes of some of the students in the back row of Class 3 who had poorer grades lit up.
It seemed like…Without Kak, the multiple-choice question ended just like that.
Most importantly, they had no doubts. Everything was very logical.
"Shut up!"
"Your grades are good, and you already know these questions. Of course, you think that the streamer's explanation is average.”
"But we're different. We think that this streamer's speech is very good.”
Immediately, Wang Meng, the slacker in the back row of Class 3, stood up and shouted angrily.
"That's right, the host spoke very well.”
"I, a slacker who usually scored 70 points, understood everything. I feel that it was better than what our Teacher Zhang Bo taught.”
Another student in the back row who did not have good grades also stood up to refute.
Zhang Bo, who was standing in the back row, rubbed his nose awkwardly when he heard that the person who spoke was better than him.
As a math teacher, Zhang Bo had the most say in whether Gu Bai's lecture was good or not.
Zhang Bo's evaluation was that there was no problem with the lecture, and it was not bad, but it was not outstanding.
But Zhang Bo didn't know…He was like those students with good grades and knew all these questions.
Therefore, they didn't know that Gu Bai's teaching had the support of 'comprehension',' inferring from one example','memory', and so on. These had an unimaginable' miraculous effect 'on those students with poor grades.
"Alright, keep quiet and continue listening.”Zhang Bo spoke up to stop the class's argument. Since the students in the back row with poor grades were so interested and so eager to learn, he naturally would not stop the live broadcast.
Gu Bai did not know what was happening in Class 3. He continued to explain the questions one by one according to his rhythm.
After the fill-in-the-blank questions were completed, the explanation of the test paper reached the main question.
The students of Class 3, regardless of whether they had good or bad grades, began to focus.
As shown in the figure, we link PG1, PG2, PG3 and extend them to the intersection points D, E, and F of AG, BG, and AC respectively.
... And because G1G2G3 =G2, the plane G1G2G3 is parallel to the plane ADC, so S → G1G2G3: S△abc=1:9。
Spatial geometry involved various knowledge points such as auxiliary lines, return lines, parallel lines, and so on. It was also one of the compulsory questions in the college entrance examination.
Although it was not as difficult as the number sequence, but…Even some students with good grades would lose points in this project.
Some of the top students even had a headache if they couldn't find an auxiliary line.
And... After listening to Gu Bai's analysis of the solution and some methods, the entire class fell silent.
The students with poor grades were a little surprised that they understood.
The students with extremely poor grades were still a little confused, but…In his daze, he also gained some enlightenment.
As for the students with average and good grades, their faces revealed a touch of shock.
That's right, he was shocked.
Gu Bai's teaching had a 20% boost to his ability to infer other things from one instance. This boost to his ability to infer other things from one instance made these students with average grades suddenly see the light of day, as if they had opened up a new world.
"F * ck, this streamer…There's something."
"That's right, that's right. I suddenly feel like I have a different understanding of finding auxiliary lines in space geometry.”
"Similarly, similarly, I have a f * cking feeling that if I encounter any spatial geometry problems in the future, I can easily solve them.”
"Awesome, this streamer is really awesome. I apologize for my offense just now."
"I apologize too. This streamer is really something. She can make people suddenly see the light and become enlightened.”
“......”
All of a sudden, the students of Grade 12 Class 3 of Sun City No.1 Middle School were in an uproar.
The students of different grades had different expressions on their faces.
There was shock, disbelief, happiness, and even enlightenment after opening the Ren Tong Meridians.
However, all their expressions told Zhang Bo, the form teacher of Grade 12 Class 3, who was standing at the back of the classroom," This streamer is really something!
