Everyone looked at the ellipses and hyperbolas that Tao Li had just drawn on the blackboard with shocked faces, and they didn't know what words to use to describe their mood at the moment. However, Tao Li was completely aware of all this, and after drawing the two conic curves of the ellipse and the hyperbola, Tao Li went on to draw the remaining parabolas.

All this, Tao Li seems to have done subconsciously. When he drew all three conic curves, and then looked at the blackboard, even Tao Li himself was surprised by the three standard curves on the blackboard:

Which handsome guy is here to paint so lifelike?!

Although Tao Li admits that his level of drawing is not low, he is not good at seeing this kind of situation, the graphics are so standard, it is no different from the geometric drawing board!

But in the next moment, Tao Li understood what was going on.

C-level picture board technology!

This is the reward from the silver treasure chest that Tao Li obtained from the last time he desperately corrected 500 assignments!

Coincidentally, the pictorial board writing technique is suitable for the content of the chapter on conic curves, and it would not have been possible for Tao Li to achieve the current effect if it had been replaced by any other board writing technique.

Chen Tianxiang, who was sitting in the back, also turned his head sideways after experiencing a short shock, and looked at Yang Zhongming beside him, the eyes of the two people were full of incredible, in addition, there was surprise and excitement!!

Judging from Tao Li's performance in so many days, they have definitely picked up a treasure this time! Yang Zhongming even felt that Tao Li was the most likely to break the record of "the youngest senior teacher" held by Chen Tianxiang in Jinling Middle School in the past 20 years, and even improved this record a lot!

"This kid is really born to be a math teacher!" Yang Zhongming couldn't help but sigh in his heart. He has been teaching mathematics for so many years, and he thinks that he has a lot of say in drawing, but when he sees Tao Li's drawing today, Yang Zhongming really feels that all these years have been in vain!

Even Chen Tianxiang and Yang Zhongming were frightened by Tao Li's trick of "fighting left and right" in these old teachers, not to mention Wang Zijing and Li Jianneng, who are also interns, especially Wang Zijing, the scene of Tao Li teasing herself last night is still vivid, originally she still wanted to see Tao Li make a funny joke, but from class to now, it didn't take ten minutes for him to conquer the whole class!

Even with so many teachers, they also praise him!

"However, he still looks quite handsome when he is in class!" Looking at Tao Li with a serious face on the podium, Wang Zijing suddenly thought like this.

"Bah, bah, no matter how handsome he is, he is a stinky rascal and a psychopath!" Wang Zijing blushed all of a sudden, and couldn't help but snort coldly in his heart.

The lecture continues!

Tao Li turned around again, with her trademark smile on her face,

"Through the first two animations and our discussions, we came up with the three curves mentioned above. Next, let's take a look at what are the common characteristics of these curves, can you use a unified definition to describe them, students, please look at the projector. ”

As he spoke, Tao Li flipped the courseware to the next page.

All the processes in the classroom, including questions, student answers, exercises, and teacher-student interactions, are completely carried out in accordance with the lesson plans prepared by Tao Li, and Tao Li's humorous and witty teaching methods have also been affirmed by the whole class.

It's the first time I've been in class, but it looks like I've been teaching for more than ten years!

It's the first time I've taken this class, but it sounds like I've rehearsed it countless times!

From the teaching methods, to the grasp of the important and difficult points of teaching, to the design of board books and courseware, Yang Zhongming and they couldn't find anything wrong, except for admiration, or admiration!

Although it is said that a full blackboard is a board book, but all the contents of the board book are scattered, the logic is clear, and each piece of knowledge points is independent of each other, and is interconnected, and a huge knowledge network is completely constructed!

Even Chen Tianxiang and they dare not guarantee that if they were to take it by themselves, the board book would be better than Tao Li's! Not to mention that before this, Chen Tianxiang had already taken this class in class 24, and in all fairness, his teaching process was far from Tao Li's!

Because of the habit of taking classes, coupled with the fact that Class 24 is the Olympiad class, the overall student base is much better, so when Chen Tianxiang writes the lesson plan, he is naturally not as attentive as he used to take ordinary classes, but now it seems that if he continues like this, I am afraid that he will be compared to Tao Li!

"In this lesson, we mainly learned the definition of conic curves and some common properties and other knowledge points, through the study of this lesson, we have a general understanding of conic curves. After you go back, I hope you can review the content of this lesson well, and then do the relevant exercises. ”

After all the content of this section was covered, Tao Li began to summarize the lesson.

"Thank you for your cooperation in this class, I will send a teaching feedback questionnaire to everyone, everyone according to my performance in this class, I will be evaluated realistically, if you have any suggestions, you are also welcome to put it forward, thank you!"

Tao Li looked at the quartz clock at the back of the classroom, there were still five minutes before the end of class, enough for him to complete this investigation!

As his first class, Tao Li needs students' evaluation of himself, which will become the main basis for him to constantly improve himself!

"What else do you say! It must be perfect!"

"That's it! Mr. Tao lectures so well, he must get full marks!"

"Everyone pay attention, don't choose all A when grading, choose D for the middle few questions, D is the most satisfied, otherwise if you choose A, it will be the most dissatisfied!"

When the evaluation form was handed out, the students at the bottom said nonsense.

Tao Li smiled helplessly, "You should at least take a look at the question, don't write the answer directly without even reading the question, I want real feedback, not to let you get a full score!"

"Teacher Tao, you are handsome, you are right in everything you say! Our real feedback is full marks!" a student immediately replied.

"Yes, appearance is justice!" another girl chimed in.

"Okay, okay, I know I'm handsome, just keep it in your heart, otherwise Teacher Chen and they should be jealous of me again!"

"Hahahaha!" The students below were amused by Tao Li's words, and the whole classroom burst into laughter.

Tao Li raised his hand and motioned for everyone to be quiet and complete this evaluation form seriously, "Students who have finished writing, pass it from back to front, and I will accept it uniformly!"

A few minutes later, Tao Li collected all the evaluation forms, and after a few simple copies, Tao Li found that they really gave themselves full marks, and it seemed that if they wanted to find the deficiencies in these tables for improvement, it was estimated that there would be no fun.

At this time, the bell for the end of class also rang, and Tao Li smiled at everyone again.

"This class is over here, thank you again for your cooperation with me in this class, after class!"
