From University Lecturer to Chief Academician

You don't need to tell me to listen carefully to the first-year class, but the substitute teacher doesn't need to be too strict.

The class bell rang.

Wang Hao immediately used the teaching coins, quickly entered the teaching mode, and filled the entire classroom with sunny and clear tones, "The content of this section is the image of the solution of the differential equation."

"There is a very classic example, the tourism competition between the capital and Donggang, both places are busy advertising to attract tourists."

"We can formulate the following system of equations, {x'=x+by; y'=cx3y}."

"Where x' stands for Donggang, y' stands for the capital, and x and y represent the deviated tourism advertising budgets of Donggang and the capital respectively..."

"In this example, we can analyze it. In the first case, Donggang's budget is positive, while the capital is calm."

"There is a point here, we need to ignore Donggang's budget..."

"..."

When the course officially started, everyone listened carefully. They followed Wang Hao's explanation and fell into understanding and thinking. They went deeper a little bit, and slowly drew the image of the solution of the equation system at the end.

The whole process is smooth and clear.

When they came back to their senses, most of the students understood it. Some students couldn't help being surprised. They found that the young teacher on the podium explained very clearly and could accurately grasp every difficulty.

When encountering difficulties, the other party will explain twice more.

This makes it easier for them to keep up with the course and understand new knowledge content. During the preview, some content that they don't understand can be understood clearly after being explained once.

Many students couldn't help but admire, "This young teacher Wang speaks better than Teacher Zheng!"

"It's clear and easy to understand!"

"I always feel that I can't keep up with Mr. Zheng's class. After listening to Mr. Wang, I seem to understand everything."

Students' feelings, in fact, are the difference in teaching efficiency.

There is not much difference in teaching efficiency at the undergraduate level, because the knowledge at the undergraduate level is the foundation, and most subjects only need to understand the basics. As long as students prepare carefully and listen carefully to the class, they can keep up with the progress.

When it comes to the postgraduate level, the difficulty of the course increases greatly, and some students can't keep up or understand even if they study hard.

"Differential Equations" is such a course.

This course requires students to have strong imagination and abstract thinking ability, as well as a very rich basic knowledge. The more difficult it is, the more difficult it is to keep up with the progress.

When the difficulty increases, the difference in teaching efficiency will be obvious.

Wang Hao has ten years of experience in middle school education. He clearly knows how to teach and how to teach students. He is much better than ordinary lecturers when explaining the same content. He also attaches great importance to the courses and will be familiar with them carefully. The teaching plan will be carefully studied for each step of the explanation.

In addition, "The Gift of Teaching" can increase the comprehension efficiency by 20%.

This is also key.

In comparison with the data, Wang Hao's serious explanation for an hour is equivalent to Zheng Yaojun's explanation for an hour and a half, or even more.

In addition, Wang Hao's explanation methods are also very rich, supported by a steady stream of inspiration, he can think of many vivid metaphors to assist teaching.

For example, when talking about a three-dimensional image problem.

Probably because some students' thinking was related to the "cosmic star movement", Wang Hao immediately thought of the "comet and star" movement law, which is very similar to the 3D image explained, so he took the "comet and star" movement law as an example , Let students imagine and understand.

With practical examples, understanding becomes much easier.

One class, two class hours.

It will be over soon.

Many students feel that the time is getting faster, and they just pass by listening to the class carefully, but they always have to miss a little bit in the past.

After Wang Hao finished the course content, he quickly assigned homework questions. After checking that there were five minutes left in the time, he said, "The following is free time. The class will end as soon as the bell rings. If you have any questions, you can come and ask."

"However, it's only ten minutes. I still have class at ten o'clock."

Several students gathered around to ask questions.

Wang Hao gave explanations to three students in a row, and their questions were all focused on a few difficult points. Later, he simply went through a difficult example on the blackboard, and then turned his head to wait for the students to digest.

At this time, get out of class is over.

He noticed the girl walking across the door, and asked with a smile, "Student, do you have any questions?"

Gu Youyou quickly covered her face with her hands, and ran towards the door with her book in her arms, "No, no, I don't have any problems!"

Wang Hao kindly reminded, "Student Li Youyou, slow down..."

Gu Youyou staggered.

She glanced back hard.

Amidst Li Qian's strange laughter of "heh, heh, heh", she rushed out of the classroom with an indomitable momentum.

...

Nine forty.

Wang Hao came to the large classroom on the second floor on time. He found a chair and sat at the door, took the student list and started to record.

Physics majors have heard the news.

Many students are full of anxiety, because it is said that one of them did the posting and reporting on the campus network.

A certain person named Ding Zhiqiang.

Ding Zhiqiang came very early, earlier than most of the students. He posted a post on the campus network, asked himself and the people in the dormitory next to him to help, and reported Wang Hao to the academic affairs.

Then, come to class again, how does it feel?

It would be fine if the report really had an effect. The most important thing is that Wang Hao had nothing to do, and he was still sitting at the door of the classroom leisurely, looking at the list and watching the students enter the door one by one.

This is...retaliation, right?

Ding Zhiqiang understood it this way, and so did the other students, and those who knew the situation couldn't help talking about him.

He pretended nothing happened.

"Keep your voice down, don't say it's me~~~ Dear friends, please keep it secret!"

"Otherwise, I must be dead!" Ding Zhiqiang hurriedly reminded pitifully when he heard someone discussing it.

Wang Hao didn't know that Ding Zhiqiang did it.

When Ding Zhiqiang came to the classroom, Wang Hao still thought he was a good student, so he arrived at the classroom fifteen minutes earlier.

He knew it was done by physics majors, and he only had one thought in his mind, "Bad students, how many floors does a bag of rice have to carry! (Feel the pain!)"

During class, Wang Hao is not at the podium most of the time, but lectures in front of the first row, in the aisle, or even at the back of the classroom.

Sleeping, playing with mobile phones, of course you have to write it down.

It is also not allowed to not listen carefully. He called those students who were "suspected to have not attended the class" to answer questions.

Ding Zhiqiang was called up twice.

Wang Hao didn't mean to target him, but because Ding Zhiqiang was not in the mood, he was always distracted because of his uneasy mood.

I was called up twice, and twice I didn't know what to say.

Of course, write it down!

In this class, the bad students majoring in physics experienced what is called a "devil's classroom".
