Xueba: The Knowledge I Teach, The Crit Is Returned

Of course, it's not just all the students in Class 3 of Senior Three who are waiting...

In the corner of the last row of class 3, Zhang Bo, the math teacher of class 3, is also full of curiosity, waiting for the start of live teaching...

As a top student who graduated from Nankai University, as a math teacher who has taught Yangcheng No. 1 Middle School for decades, Zhang Bo does not believe in miracles, nor does he believe in some inexplicable rapid progress. He believes that hard work brings rewards.

Therefore, he felt that it was inappropriate to stand here.

But... student Liu Yanyan's math score improved by 50 points in a short period of time, which really aroused his curiosity.

He wants to know... what kind of anchor teaching anchor has such ability, or he wants to know the real reason for Liu Yanyan's rapid progress.

"It's started, it's started!"

Suddenly, a student shouted loudly with his phone held up.

Immediately, the entire Class 3 of the third year of high school fell silent.

All the students turned their attention to the projection curtain on the podium, and the screen also appeared on the curtain.

What caught my eye was a 'light yellow' wooden desk. On top of the desk was a mock exam paper for the college entrance examination, a piece of scratch paper, and a black signature pen. It was simple but concise.

"Hello, all the students of Yangcheng No. 1 Middle School, Class 3, Senior Three."

"Welcome to the Learning Live Room."

"Let's start teaching."

No extra nonsense, after a simple opening remark, Gu Bai started teaching.

Liu Yanyan sent a message before Gu Bai's live broadcast to explain that this time, Class 3 collectively watched the live teaching on a large screen, so Gu Bai didn't care about the number of live broadcasts in the live room.

Anyway, as long as the students in class 3 of mathematics knowledge he was teaching could understand, the system would reward him.

"Set M={2,4,6,8,10}, N={x|-1x6}, then M∩N=()"

"A.{2,4}B.{2,4,6}C.{2,4,6,8}D.{2,4,6,8,10}"

"Set is one of the compulsory questions in the college entrance examination. If you want to master the concept of set, you must set it immediately, such as subset, intersection, union, complement..."

In this way, Gu Bai started his teaching according to the order of the test papers.

Because it is facing the whole, considering some poor students, Gu Bai will explain whether it is simple or not.

soon.

After finishing the selected topic, some students with good grades in the class said:

"It's so-so, it feels similar to what our math teacher said."

"Yeah, nothing special."

"Hey!! The bigger the expectation, the bigger the disappointment."

After all, these questions are still very simple for these high-achieving students, and they will already know them.

However, some students with poor grades in the back row of Class 3 are bright.

It seems... without Kak, the multiple-choice questions just end like that.

The most important thing is that they don't have any doubts, and everything is very logical.

"To shut up!!!"

"You have good grades. These questions are already known. Of course, I think the anchor is general."

"But we are different, we think the anchor speaks very well."

Immediately, Wang Meng, a scumbag in the back row of class 3, stood up and shouted angrily.

"Yes, the anchor speaks very well."

"I, a scumbag who usually scores 70, has understood everything. I feel it is better than what our teacher Zhang Bo said."

Another student in the back row with poor grades also stood up and retorted.

Hearing it was better than what he said, Zhang Bo, who was standing in the back row, rubbed his nose awkwardly.

As a math teacher, Zhang Bo must have the most say in Gu Bai's speech.

The evaluation given by Zhang Bo is: there is no problem with the teaching, and the teaching is also good, but it is not excellent.

But Zhang Bo didn't know it was... He, like his classmates with good grades, knew all these questions.

So I know that Gu Bai's teaching has the blessings of 'comprehension', 'inferring others', 'memory', etc., and these have unimaginable 'miracle effects' for those students with poor grades.

"Okay, keep quiet and continue listening to the class." Zhang Bo spoke out to stop the quarrel in the class, but the students with poor grades in the back row were so interested and eager to study, of course he wouldn't stop the live broadcast.

Gu Bai didn't know what was going on in Class 3, and continued to explain question by question at his rhythm.

With the completion of the fill-in-the-blank question, the explanation of the test paper has reached the big question.

Class 3 students with good or bad grades began to concentrate.

[As shown in the figure, we have linked PG1, PG2, PG3 and extended them to intersect with AB, BC, AC at points D, E, F...]

[...and because G1G2∩G2G3=G2, the plane G1G2G3 is parallel to the plane ABC, so S△G1G2G3: S△abc=1:9. 】

Spatial geometry involves various knowledge points such as auxiliary lines, return journeys, parallel lines, etc., and is also one of the compulsory questions in the college entrance examination.

Although its difficulty is not comparable to the sequence, but... even some students with good grades will lose points.

Even if the auxiliary line cannot be found, some academic masters have some headaches.

And... After listening to Gu Bai's analysis of the problem-solving ideas and some methods, all the students in Class 3 fell into silence.

The students with poor grades were a little surprised that they understood.

The students with super poor grades are still a little confused, but...the confusion also has some insights.

The students with average grades and good grades had a look of shock on their faces.

Yes, just shocked.

20% of Gu Bai's teachings are inferred from one another, and this kind of blessing of the ability to infer three from one thing makes these students with average grades suddenly enlightened and opens up a new world.

"Fuck... this anchor... has something."

"Yes, yes, I suddenly feel that I have a different understanding of finding auxiliary lines in spatial geometry, and the whole person seems to have suddenly become enlightened."

"The same thing, I feel that I will be able to solve the problem of space geometry in the future."

"It's awesome, this anchor is really awesome. I apologize for my offense just now."

"I also apologize, this anchor is really in stock, it can make people suddenly enlightened, like suddenly enlightened."

"..."

Immediately, all the students in Yangcheng No. 1 Middle School, Class 3, and Senior 3 boiled over.

The faces of students in different grades showed different expressions.

Some were surprised, some were incredulous, some were happy, and some even had an epiphany through Rentong’s second pulse.

But all the expressions are telling Zhang Bo, the head teacher of Class 3, who is standing at the back of the classroom: This anchor is really in stock! ! !
