Ning Yunxi secretly changed several times. It should be said that this situation is not the first time for her. She is familiar with her twice. Now, her psychological quality is much better than teaching the Heroes on the first day.

He walked into the classroom with the teacher's briefcase.

The students in green military uniforms stood up and saluted: "Hello teacher!"

Ning Yunxi stood behind the podium and faced the classroom with a smile: "Hello, classmates."

The graceful and generous attitude and calm and stable voice, the calmness and confidence that were not in line with her young face, surprised and surprised all the students who took Teacher Ning class for the first time.

The students sat down neatly.

Ning Yunxi picked up the chalk and went to the blackboard to write the topic we want to talk about today: Graph Theory.

"Students, can anyone tell me what graph theory is based on these two words I wrote?"

There was a silence in the classroom.

Teacher Ning did not give up easily and said, "I mean the superficial meaning of these two words can make you think of."

Some students raised their hands boldly.

"Please stand up and speak." Teacher Ning made an invitation gesture.

The soldiers and students are different. They stand up like gusts of wind, standing upright, and their answers are loud like a bell: "Teacher, I think this should be said about the theory of the diagram."

Some students sitting below started to hold it in, thinking that it was not that simple. Unexpectedly, Teacher Ning really said: "Yes, this student said this. Graph theory is a mathematical theory formed by using graphs as research objects."

There is shocking everywhere inside and outside the classroom.

Ma Xiaoli and her medical instructor stood outside the classroom with Jiang Wenli to listen. He only listened to the beginning of Teacher Ning. The medical school teacher listened with relish and said, "Teacher Ning is very good at teaching. When he first gave a lecture, he immediately raised the curiosity of all students."

Interest is the best motivation for learning. A good teacher will firmly grasp this point and arouse students' interest in the classroom all the time. However, it is very difficult for teachers to do this. You cannot read the textbook according to the textbook. Just by teaching in the textbook, if you think good students will definitely preview the textbook first, will you think it is interesting for the teacher, you repeat the textbook?

Even if you are talking about the knowledge in the textbook, a good teacher must extend and expand. This requires the teacher to have too deep academic skills, otherwise it will not be possible. Therefore, there is a saying that good teachers are hard to find.

Several school leaders came to the corridor and were already communicating with Jiang Wenli.

"Have Teacher Ning started the graph theory class?" the leader asked.

Jiang Wenli nodded: "Yes." While answering, she was actually helping Ning Yunxi feel sweaty in her heart. By the way, it was not only her, but the military academy leaders who decided to ask Ning Yunxi to teach the military academy students were also very nervous.

The main thing is that people who know graph theory are, and they all know how difficult it is. It is said that this course is difficult that thirty people in the country can’t come up with a picture theory, so is it easy to hire a teacher who talks about graph theory? The leaders of the military academy are unsure. However, if you can really hire such a teacher, it would be a big profit.

The military academy leader who had taken a class in Ning Yunxi was eager to try it out, and he had some hope and confidence in Ning Yunxi. He hoped that Ning Yunxi could try it out. Unexpectedly, Ning Yunxi agreed.
