Xueba: The knowledge I taught will be returned by crit

Of course, it’s not just the entire 3rd class of high school who is waiting….

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

As a high-achieving student graduated from Nankai University and a mathematics teacher who has taught at Yangcheng No. 1 Middle School for decades, Zhang Bo does not believe in miracles, nor does he believe in any inexplicable leaps and bounds, he believes that hard work will reap the rewards.

So, he felt that it was quite inappropriate for him to stand here.

But… Student Liu Yanyan improved her math score by 50 points in a short period of time, which really aroused his curiosity.

He wanted to know… What kind of anchor teaching anchor has such ability, or he wants to know the real reason why Liu Yanyan’s performance has improved by leaps and bounds.

“It’s started, it’s started!”

Suddenly, a student held up his mobile phone and shouted.

Suddenly, the entire third class of high school fell silent.

All the students looked at the projection curtain on the podium, on which a picture also appeared.

What catches your eye is a ‘light yellow’ wooden desk, on which is placed a college entrance examination mock test paper, a piece of scratch paper, and a black signature pen, simple but concise.

“Hello to all the students of the third class of Yangcheng No. 1 Middle School and High School.”

“Welcome to the Learning Live Room.”

“Let’s start teaching.”

There was no unnecessary nonsense, and after a simple opening remark, Gu Bai began teaching.

Liu Yanyan sent a message before Gu Bai’s live broadcast to explain that this time the 3 classes collectively used the big screen to watch the live broadcast teaching, so Gu Bai did not care about the number of live broadcasters in the live broadcast room.

Anyway, as long as the students of the 3rd class of the math knowledge he teaches can understand, the system will give a reward.

“Set M={2,4,6,8,10},N={x|-1×6}, 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, and if you want to master the concept of collection, you must immediately set the concept, such as subsets, intersections, unions, complements…”

In this way, according to the order of this test paper, Gu Bai began his teaching.

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

Soon.

After the multiple-choice questions were given, some students in the class who had good grades said:

“Ordinary, it feels similar to what our math teacher said.”

“yes, nothing special.”

“Hey!! The greater the expectation, the greater the disappointment. ”

After all, these topics are still very simple for these students with good grades, they would have been.

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

Seem… Without Chuck, the multiple-choice questions ended like that.

Most importantly, they didn’t have any doubts, and everything was very logical.

“Shut up!!!

“You guys have good grades, these questions would have been, of course, I think this anchor is general.”

“But we are different, we think this anchor is very good.”

Immediately, the scumbag king in the back row of Class 3 stood up abruptly and shouted angrily.

“That’s right, the anchor said very well.”

“I understand all the scumbags who usually score 70 points, and I feel better than what our teacher Zhang Bo said.”

Another classmate in the back row who did not get good grades also stood up to refute.

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

As a mathematics teacher, Gu Bai speaks well or not, and Zhang Bo must have the most say.

Zhang Bo’s evaluation is: there is no problem with teaching, and the lecture is good, but it is not excellent.

But Zhang Bo didn’t know what it was… Like his classmates with good grades, he will do these questions.

Therefore, I know that Gu Bai’s teaching has blessings such as ‘understanding’, ‘inference’, and ‘memory’, and these have unimaginable ‘miracles’ for those students with poor grades.

“Okay, keep quiet and continue to listen to the class.” Zhang Bo spoke out to stop the quarrel in the class, and the students with poor grades in the back row of the class were so interested and motivated to study so fiercely, of course he would not let the live broadcast stop.

Gu Bai did not know what happened in Class 3, and continued to explain question by question at his pace.

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

Class 3, whether the students with good grades or poor grades, began to concentrate.

[As shown in the figure, we have linked PG1, PG2, PG3 and extended the intersection with AB, BC, and 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, involving various knowledge points such as auxiliary lines, return distances, and parallel lines, is also one of the compulsory questions for the college entrance examination.

Although it is not as difficult as a series, but… Even some students with good grades will lose points.

Even, if you can’t find the auxiliary line, some top students also have some headaches.

Whereas… After listening to Gu Bai’s ideas for analyzing the problem solving and some methods, all the students of the entire 3rd class suddenly fell into silence.

Students with poor grades were a little surprised that they understood.

Students with super poor grades are still a little confused, but… There is also some realization in the confusion.

The students with medium grades and good grades showed a look of shock on their faces.

That’s right, just shock.

Gu Bai’s teaching has 20% of the blessings of one inference, and this blessing of the ability to draw inference from one to three makes these students with high grades suddenly open up a new world.

“Groove…. This streamer… Something. ”

“That’s right, that’s right, I suddenly feel that I have a different understanding of finding auxiliary lines in spatial geometry, and the whole person seems to suddenly open up.”

“Similarly, my special feeling that if I encounter spatial geometry problems in the future, I can easily solve them.”

“Awesome, this anchor is really awesome. I apologize for the offense I just made. ”

“I also apologize, this anchor is really in stock, it can make people suddenly cheerful, suddenly enlightened.”

“……”

Suddenly, the students of the third class of the entire Yangcheng No. 1 Middle School and High School boiled.

The faces of the students in different grades showed different expressions.

There are surprises, incredulousness, happiness, and even the epiphany that opened up Ren Tong’s two pulses.

But all the expressions are telling Zhang Bo, the teacher of the third class of high school, standing at the back of the classroom: This anchor is really in stock!!!
