Monday morning.

Partial Differential Equations is now available in a new curriculum.

Wang Hao settled the 'Cauchy problem' task and did not establish a new R&D task, because the content of the new week's course was only the transformation solution of equations.

One is to solve using the separation variable method.

The other is the Laplace transformation method to solve.

The difficulty of the knowledge content of equation solving is relatively low, and it is difficult to find the direction of research and development, at most it is just to improve the proficiency of solving equations.

In this regard, there is no need to establish R&D tasks at all, and normal lectures can increase knowledge and ideas, and the goal can be achieved.

However, Wang Hao is still looking forward to the new week's course.

Because the research and development of 'task 1', 'common solution of specific partial differential equations', is directly related to the method of solving equations, when the content of the explanation is strongly related to the research and development content, it is easy to get inspiration.

[Task 1]

[Inspiration value: 82.] 】

Wang Hao glanced at the progress of the R&D task, and suddenly became more expectant.

Monday is for applied math majors.

Wang Hao is full of good feelings for students majoring in applied mathematics, because there are very few students who skip classes in applied mathematics majors, and they are not even late for two weeks, and most of the students are also listening carefully, and they are very serious without special supervision.

Teachers like serious students.

"Partial Differential Equations" was originally a course in the Department of Mathematics, and Wang Hao decided to use a new teaching method to explain the basics.

Come up, just talk about the topic.

Starting from the lecture and the new solution, slowly guide the students to think about learning new knowledge, whether it is for the student or for himself, it may bring good results.

Wang Hao stood on the podium and took notes--

Teaching experiment (2): Lecture in a multi-guided manner, and solve equations by separating the variable method and the Laplace transform method.

Then, a teaching coin was used and invested in the research and development of 'Task 1', officially opening the teaching mode.

Equations, new solutions, are relatively less difficult to solve.

The method of separating variables is hardly difficult at all, even if you only have the foundation of high school, you can roughly understand it.

The content is simple, and the course goes smoothly.

Wang Hao didn't need to repeatedly emphasize some difficult points, the speed of progress in the first half of the class was very fast, and he assigned an exercise in the middle of the class, and after giving time to explain it carefully, it was the content part of the Laplace transformation method.

The Laplace transform, also known as the Laplace transform, is an important method for solving linear ordinary differential equations with constant coefficients.

When using the Laplace transform to solve the problem of a linear ordinary differential equation with constant coefficients into a linear algebraic equation or a system of equations, the initial conditions can be taken into account, and there is no need to find a general solution and then a special solution.

This has a wide range of applications in engineering technology.

The Laplace transformation method is a very important method, but it is also difficult, and Wang Hao explained it patiently.

When it comes to difficult basic content, it is obviously much more difficult for students to think and understand it if they want to explain it in a guided way.

Wang Hao found that he was more inspired.

A large number of thoughts appeared in his head, and he paid attention to the progress of 'Task One', and in just twenty minutes, he gained '4' inspiration points.

"Sure enough!"

"When students think more, they get inspiration faster, but when they just record the basics, it's hard to get inspiration."

"Difficult basic content can also be used to guide teaching!"

"It also helps students improve their imagination and thinking skills."

"It's a win-win again!"

Wang Hao has been more energetic in class.

……

After class, the class dragged on for ten minutes, and no students complained.

Wang Hao was very pleased.

Practice has shown that strict requirements make students fall in love with learning, but does it matter if it is voluntary?

He went to the faculty cafeteria.

Eat, go back to the office.

I opened the system and checked the progress of the task, and found that the inspiration value had increased by '11 points', and I suddenly became very excited.

'Task 1', the inspiration value is about to reach hundreds.

This meant that the 'longest-lasting' study would soon bear fruit, and he immediately began to make a 'record of experiments' --

Teaching experiment (2): Lecture in a multi-guided manner, and solve equations by separating the variable method and the Laplace transform method.

The first class, target: students of the Department of Applied Mathematics, 99 students.

Results: The difficulty of students' understanding of the Laplace transformation method increased, and the teaching time was slightly extended......

"Wang Hao!"

There was a shout at the door.

Wang Hao turned his head in surprise, and saw Zheng Yaojun standing outside the door, looking a little timid and cowardly, as if he was worried that others would see it.

"Please come in?"

"Say it in the hallway?"

Wang Hao was puzzled, "Let's come in?" What can't be said directly? He moved a stool and put it next to him.

Zheng Yaojun shrank by the door and spoke quietly, and kept looking at the others outside the door and in the office, as if he was worried that others would hear.

Of course he didn't know that there was a 'gossip elite' not far away, and he had already pricked up his ears with curiosity.

"That's right."

Zheng Yaojun sighed and said, "Wang Hao, you can trap me." When I came back, I heard from the students that I didn't give a lecture as good as you, not just one person, but a group of people, as if all the students saw it that way. ”

"You have such a good relationship with students?" Wang Hao was a little surprised, and a group of students said that it must not be in private, it should have been said in class.

Zheng Yaojun was suddenly a little proud, "To treat students is to have affinity." Let them say what they feel, so that they can teach well. This is my experience. ”

"Uh-huh."

Wang Hao thought about it carefully, there is really no need to be very strict with the treatment of 'graduate students who love to learn', and there are very few graduate students who do not study.

He asked suspiciously, "And ...... are you?" ”

Zheng Yaojun's voice became smaller again, he almost leaned into Wang Hao's ear, and said softly, "I'm here to learn from you, I want to know how you lecture, why everyone says you are good?" ”

"This ......"

"I can say that."

Wang Hao is still confident in his teaching ability, "The Gift of Teaching" improves students' understanding by 20% is only one aspect, on the other hand, he does have rich teaching experience, and knows how to speak to make it easier for students to understand.

The two whispered.

This said that it was more than half an hour, Zheng Yaojun did come to 'learn from the experience', and took out a pen and paper to make a record.

Subsequently, he sighed, "You are really good at teaching, and there are some methods that I haven't thought about at all." ”

Wang Hao said, "You can talk to Professor Wang Huanxin, I talked to him about teaching methods last time, I feel that I have gained a lot, and Professor Wang is very enthusiastic, he likes to talk about things related to teaching experience." ”

Zheng Yaojun nodded and wrote it down.

We're done talking.

Zheng Yaojun thought that he was also familiar with Wang Hao and was a friend, so he sat down and chatted with Wang Hao, and immediately turned the topic to 'business trip', "I went abroad this time, and the harvest was really great!" ”

"In a week, I listened to three morning lectures, and I was deeply impressed by a professor at Oxford University named Brooke, who was ...... hyperbolic functions."

He said a whole bunch in a row.

Then he continued, "In addition to the academic report, other gains are also very large. Mumbai is really good, I always thought it was poor, but it was not as poor as I imagined, and the environment in the city is really good. ”

"I've been to several tourist places, there are a lot of people, but I'm not used to eating, and I always feel a little dirty......"

"For a week, I spent 20,000 yuan on frugality, but fortunately, I can be reimbursed!"

Zheng Yaojun exhaled lightly, his tone sounded a little happy, but the last sentence was very loud, and everyone in the office could hear it.

Everyone looked at it collectively.

After he finished speaking, he seemed to be happy, and then said the last thing, "By the way, Wang Hao, say okay, two classes, a thousand yuan, I'll transfer it to you." ”

Wang Hao picked up his mobile phone with a dark face, and wanted to blast him away quickly, but suddenly stopped and asked, "We don't repeat the lessons, right?" ”

"yes."

"That's it, the day after tomorrow, the day after tomorrow, you can also help me with two classes, don't give money, help each other."

Zheng Yaojun was very happy to hear it, there was only a thousand yuan left with two classes, which was equivalent to making extra money, he asked suspiciously, "Do you have something?" ”

"Go to Hanghu Lake and give a presentation."

"On a business trip! Does the school give you a newspaper? ”

"No retribution." Wang Hao shook his head in denial, and said casually, "But the organizer gave me a report, and he had to give me 200,000." ”

"Ah~~"

He let out a long sigh, "How can you talk about money when it comes to academic matters?" These big companies are too philistine! ”

Zheng Yaojun was a little stunned when he heard it.

Zhu Ping listened to it for a long time, and she had already seen that Zheng Yaojun was unhappy.

She immediately pulled Zheng Yaojun enthusiastically and said, "Wang Hao, I was invited to give a speech, go once, two days and one night, and the appearance fee is 200,000!" ”

"Full reimbursement!"

"You talk about it, you talk about it!"

"How can you talk about money in academic matters, Professor Zheng, isn't that so? This kind of big company just can't do it! ”

“……”

Zheng Yaojun suddenly felt that he couldn't stay any longer, and he said definitely before leaving, "Wang Hao, it's okay, the day after tomorrow, the day after tomorrow, I'll help you substitute for you." I won't give the money. ”

"Good!"

Wang Hao suddenly felt that Zheng Yaojun's personality was not so bad.
