"Functions are fundamental, and the messy and complex concepts are not to be mentioned, and the three basic elementary functions, exponential functions, logarithmic functions, and power functions, are like three roles in a family......"

Just after saying a paragraph, Zheng Dazhong's eyes lit up, he was an expert, and he immediately understood the height of Liu Chen. Pen & Fun & Pavilion www.biquge.info

Many teachers are only in this mountain, and they can't do it from a high position.

Sun Shuren nodded frequently.

The other teachers put away their contempt and all listened earnestly.

The students couldn't understand why Liu Chen didn't apologize when he came to the podium, but gave a lecture, and they didn't care about what he said at first, but after listening to it for a few minutes, they felt different, his analogy of the three basic functions was too vivid, and he never thought that he could make such an analogy, and he remembered it deeply in an instant.

In just a few minutes, the definitions and transformation relationships of the three basic functions were clearly explained, and the teachers had been teaching for several days, and many students were still listening to them.

That's the difference.

This is a lively and relaxing class, there is no feeling of torment at all, it turns out that learning can be so simple.

It's like telling you how to spread the mountain, and then telling you how to climb it, and what pitfalls and dangers there may be along the way, which many teachers can't do.

Most of the teachers at this stage are a group of people who were not so prominent in their reading back then, and even most of them are typical of dead reading, so the way to tell students is to work hard, work hard, and work hard, how to spend the least amount of time to learn the most knowledge? They don't know, because they haven't reached that realm!

The acquisition of knowledge can be said to be a human instinct, provided that it is not boring and boring, otherwise people with poor perseverance and endurance will not be happy.

Gu Witch looked at Liu Chen, who was steady and chatting and laughing, and felt a kind of trance at the moment, where is this still a student, it is better than the most skilled teacher lecturing.

As a liberal arts student, she actually hates mathematics, and those things that change back and forth are too mind-blowing, and she can't help but think that if such a humorous and knowledgeable teacher gave a lecture back then, she would definitely have a great interest in mathematics, and maybe she would have a crush on the teacher obsessively.

Du Ning's face was flushed with excitement, just like he was lecturing on the stage, and even more excited, haha, I just said that the boss is definitely a bull, and mathematics is so good, usually give me a little guidance, this time it has improved so much.

Meng Qingqing looked at the boy on the stage, sometimes writing and drawing on the blackboard, and sometimes humorously giving an example, such a boy is the focus of everyone's attention, with a halo on his body, and the always proud school flower is fascinated.

The colonel flower is still like this, not to mention Yang Xue, her two eyes are full of little stars, she is fascinated, her two hands are tightly grasped and twisted, she only feels that the whole person is in a state of excitement, her brain is gradually emptying a little, and Liu Chen on the podium has completely changed her appearance.

She became a prince in a medieval castle, dressed in luxurious clothes, with a sword pinned to her waist, and her demeanor, and listening to his magnetic voice, every word and note seemed to hit the tip of her heart, and she only felt that the whole person was extremely hot, and her face was even more red and hot.

Sun Shuren took off his glasses and rubbed his eyes, his eyes were a little moist, the education method he had pursued for so many years was like this, but he never reached it.

Zheng Dazhong couldn't help himself with excitement, and whispered: "This kid is stronger than me, stronger than me......"

Xiao Rongsheng was pondering something.

Mathematics teachers are all enlightened, why can't they explain these knowledge points that they are too familiar to be familiar with?

Compared with his own teaching methods, Zhao Hua's whole face was ashamed like a big red cloth, and he was like sitting on pins and needles all the time.

Liu Chen did not force anyone to listen carefully to the class, but every student couldn't take their eyes off it and recorded it in their notes from time to time.

Qian Shuai looked at the classmates around him, his mouth couldn't be closed when he opened his mouth, how could this be? When did Liu Chen become so clever, why didn't he apologize to Teacher Zhao Hua, but went to the stage to give a lecture, and suddenly thought of the most terrifying situation, could it be ......

Liu Chen won against Zhao Hua?!And it exceeded 650 points, which ...... How can it be.

There is also a girl in the class who studies physical education, Ma Ting, after Gu Witch said that everyone should talk to Liu Chen, she also asked Liu Chen for questions, Liu Chen patiently explained to her every time, looking at Liu Chen who was talking and laughing at the moment, I only felt that a boy could not be more attractive.

When the bell rang for the end of class, the students felt unsatisfied, and spontaneously stood up and applauded vigorously.

Sun Shuren walked slowly to the podium, and the restless classmates instantly quieted down, this kind and kind old man had a kind and kind old man's magic.

"Judging from the applause of the students, everyone has gained knowledge, I am very happy to see Liu Chen's teaching, so that I am an old man, the young man's energy is unlimited, the imagination is strong, the students have practiced each other's spontaneous teaching method in foreign countries, but due to limitations have not been promoted, no matter what, we still have to listen to the opinions of a few teachers, what do you think Liu Chen's teaching is?"

As soon as the words fell, Zheng Dazhong shouted: "Okay, good, it's too good, what do you think?"

The teachers originally thought it was good, and Zheng Laodu was the first to support it, and they naturally agreed.

Xiao Rongsheng said: "Students, you should be glad that in Class 2 of the third year of high school, Liu Chen is willing to make selfless contributions. ”

All the teachers voted unanimously and no one objected.

Sun Shuren continued: "I once told Liu Chen, this is a thankless task, although he did speak very well, the teachers also support, but also to be recognized by the whole class, the school's principle is that every student must be recognized, as long as one disagrees, no, the next month and a half, Liu Chen will tutor you in mathematics, agree, please raise your hand." ”

Du Ning was about to raise his hand as fast as he could, but found that he was preemptive, it was Ma Ting, a sports student, her face was full of smiles, the little girl was actually not ugly, but she was dressed too neutrally, and she looked like a handsome little brother, which was very inconsistent with the aesthetics of high school students.

Meng Qingqing also raised her hand in support without hesitation, no one knew the excitement in her heart, when everyone was not optimistic about Liu Chen and belittled him, she always insisted on Liu Chen's strength, Lan Xinhui naturally understood what it meant for Liu Chen to be on the podium today.

Wow, the students' hands were raised all at once.

Sun Shuren checked them one by one until he saw a classmate who didn't raise his hand.
