"I see that many of you have very bad study habits, I just saw someone find the original formula in the textbook, and draw the formula with a pen on it, the formulas in the textbook are separated, and when you want to use it, you have to turn it over, you find a book to copy it down, all of them are gathered together, and then it is more convenient to find it?

I also saw some students casually tear up a piece of paper and copy it and clip it to the book, what if the paper is lost? Also, the previous classmate actually copied the formula in English, aren't you afraid that your English teacher will see it? In the future, everyone should prepare a notebook for mathematics, and don't mix it with other subjects. A separate notebook is dedicated to math notes, so that it is easier to find, and you have to learn to study efficiently and save time. Su Chen said to the students earnestly.

The next two multiple-choice questions Su Chen also quickly explained, they are all small traps, it is not difficult to say how difficult, as long as you are serious, you will not make mistakes.

Later, he talked about a problem of solving equations, this problem, Su Chen found that everyone in the class asked him to explain, so he asked.

"Won't you know this question? It's very simple, the person who got this question right raised his hand. Seeing so many people asking him to talk about this topic, Su Chen felt that something was wrong, so he asked.

The class was silent, and it was clear that no one in the class got this question right.

"Is it that hard? Give you 3 minutes, you do it again, and I'll find someone to solve it later. Su Chen felt that it was necessary to focus on it, but he just wrote the answer for them, maybe they would suddenly understand, and then they all understood.

But the next time they meet again, they won't necessarily remember it. So Su Chen decided to let them solve it first, and then he would solve it again, so as to deepen the impression of the students.

Three minutes passed, and Su Chen saw that the people below were still scribbling there with their heads down.

"Okay, when the time comes, who will solve it?" Su Chen didn't give the students an extension of time, because it was very simple for him to extend the time, but he wouldn't give you an extension of time in the college entrance examination room. So Su Chen didn't do it.

Looking at the people below, you look at me, I look at you, and no one is willing to come up and answer. Seeing this, Su Chen asked directly, "Who is the squad leader?" ”

At this time, the eyes of the whole class turned to Gong Nana.

Su Chen also stopped at Gong Nana's body with everyone's eyes.

"Okay, squad leader, come up and solve this problem." Su Chen didn't let her water out of the test paper because he took Gong Nana's test paper, because on the test paper, Gong Nana also made a mistake.

Being stared at by everyone, especially Su Chen, Gong Nana was a little nervous, but she couldn't retreat, after all, she was the leader of the class and represented the class, so Gong Nana gritted her teeth and stood up and walked to the podium.

Su Chen took the initiative to hand her the pen, and then walked off the podium.

In Huacheng Experimental Middle School, in order to reduce the health impact of dust on teachers, it no longer uses chalk to teach, and it is replaced with whiteboards and pens. Of course, there is also a multimedia blackboard, general mathematics and other classes can be taught with a multimedia touchpad, on which you can simply draw a variety of pictures, and the blackboard does not need to be cleared directly with one click.

However, Su Chen didn't turn on the computer, so he still wrote on the whiteboard with a pen.

Su Chen didn't go to see how Gong Nana solved on the podium, but went under the classroom to see how other students answered.

A few minutes passed, Gong Nana also came down from the podium, and Su Chen also walked around the classroom.

"Just now I took a turn below, and I also looked at a lot of classmates, and none of them did it right, and many people couldn't even solve half of it." Su Chen walked around and returned to the podium and said.

When many people heard Su Chen's words, they all lowered their heads in shame.

"Raise your heads, you won't go to school, it's not the college entrance examination now, you still have a chance, and you still have time. What are you doing with your heads down? No one is born with knowledge, and after learning it, it will be enough, and if you can't, you will be able to do it a few more times. Let's take a look at how the squad leader is doing. Su Chen saw that the group of girls below all lowered their heads, and couldn't help but reprimand.

"Step 1...... Well, it's okay to do that.

Step 2, why did you get rid of X? You just casually got rid of X, have you considered X's feelings? Su Chen originally explained it well, but when he suddenly saw what made Su Chen feel incredible, he couldn't help but complain.

"Hahaha, have you considered X feelings?" The whole class burst into laughter when they heard this.

Gong Nana was even more blushing like a monkey's buttocks, not daring to look at people.

After the class quieted down, Su Chen directly wiped Gong Nana's problem-solving process, and then explained it seriously.

After speaking, the whole class suddenly realized, and estimated that this sentence "Have you considered X's feelings?" "It will make students never forget this type of question in the future.

After that, Su Chen systematically explained to the students, one of the questions, Su Chen summed up 6 different solutions, and then derived other question types from this question, and summarized several test methods for a knowledge point and all the solution ideas and methods.

The students in the class went from being careless at the beginning to now beginning to take out their notes and record them desperately, for fear that they would be slow and miss these notes.

This kind of notes on all the question types and solutions covered by one knowledge point is tantamount to a "martial arts cheats" for students, with it, understand, this type of question will not be wrong in the future.

If you are still wrong, you can only say that you haven't learned it yet. Because that's already all the standard answers.

In such an atmosphere, a volume was quickly finished.

The main thing is that the first class of the third year of high school belongs to the top class, and there are not many wrong questions, if it is another class with poor grades, it is estimated that the whole paper will have to be explained.

Most of the time was used by Su Chen to systematically summarize the problem types, solutions and formulas for them.

After speaking, there were still a few minutes left in a class, Su Chen's mouth was a little dry, and now Su Chen missed being a physical education teacher a little, at least he didn't need to keep his mouth moving.

At this time, most of the students had finished taking notes, and a tall female classmate raised her hand to ask a question.

"You say," Su Chen stretched out his hand and motioned for the female classmate to speak.

"Teacher, can you always teach us math in the future? I think you teach us so well, when Mr. Huang taught us in the past, he wrote the answers directly on the blackboard, and did not give us the inductive question types and multiple solution methods, and often scolded us for being stupid when we made mistakes. The tall female classmate thought of Teacher Huang's class scene in the past and recalled.

"Yes, yes, it's still the teacher you said well, Teacher Huang didn't know how to talk in such detail before." The students below also chimed in.
