Chapter 147

The time for the first class passed in a hurry.

In college, it is common for two small classes to be combined into one large class.

After letting the students take a simple break for ten minutes, Gu Lu continued the class.

Gu Lu did not continue to check the students' preview results, but directly talked about the main class.

The course "Mathematical Analysis" is similar to "Advanced Mathematics" in terms of content.

The content covered is all extreme integral derivation.

But there was a difference between the two before.

Mathematical Analysis focuses on principle analysis, while Advanced Mathematics focuses on applied practice.

To put it simply, it means that there are many proof questions in the math course, and there are many questions in the advanced math course.

Of course, in terms of overall difficulty, mathematics is more difficult than advanced mathematics, which is a basic compulsory course in science and engineering.

But in Gu Lu's eyes, both of these are courses that can no longer be basic, and naturally there is no difficulty or ease.

The first chapter of the number of points, functions.

The main content is to introduce the concepts of real numbers and functions, as well as the properties of functions, such as the monotonicity of functions, the boundedness of functions, the periodicity of functions, and so on.

All of them are the contents that have been learned in high school, and they belong to the foundation of the basics.

"Mathematical analysis is mainly composed of calculus and series theory, and its main object is the real function, that is, the function with the real number as the independent variable and the value of the real number.

In college, the speed of lectures is generally much faster than that of high school teachers.

In high school, it was a few classes that taught a chapter.

But in college, it's a few chapters in one class.

The speed of the lecturer has become faster, which is also quite a challenge for the students who are listening to the class.

Maybe you haven't made the transition from high school yet.

Twenty minutes later, when Gu Lu said this, "I've finished the first chapter, let's look at the second chapter." At that time, many people's minds were completely confused.

That's ...... That's it!

That's nearly thirty pages of content, and it took less than twenty minutes before it was gone?

It's just brutal!

It doesn't give people time to react at all!

In the first class, they were gearing up and ready to do a great job, but they were tortured to death by Gu Lu's four questions.

In the second class, it was finally time to teach the main class, but they found that it was extremely difficult to even keep up with Teacher Gu's lecture speed at the very least.

This math class has really become a large-scale autistic scene.

"Teacher, can you speak a little slower, I can't keep up. A classmate raised his hand weakly.

"This is your first class at the university?" Gu Lu didn't answer directly, but asked with a smile.

The students in the audience nodded in unison.

"That's right. Gu Lu smiled, "You shouldn't have experienced the teaching speed of other teachers, but after you have experienced it, you will feel that my teaching speed is already benevolent." ”

To be honest, Gu Lu's lecture speed is really not fast.

Let some old professors come, and it is estimated that they will be eager to finish the entire textbook in one class.

Gu Lu started the Dundun teaching mode, "Since I came to the university, I have to adapt to this rhythm of lectures. The university courses are very relaxed, which naturally means that there will not be too many teaching hours for each course, and there will be too much content to be taught, so it can only speed up the pace of lectures. A situation like yours in high school where you teach a chapter in seven or eight classes is unlikely to happen in college. ”

"Of course, the relaxation of the curriculum also means that your spare time increases. There is no morning self-study, no evening self-study. There are only one or two big classes a day, and I want you to make use of the time you have free. Do a good job of preview before class and review after class, so that the efficiency of class can be twice the result with half the effort. ”

"The reason why you can't keep up with my lectures is probably because you don't do enough pre-study. Gu Lu felt that it was necessary to let the group of students in front of him get rid of the mode of being forced to study by teachers in high school.

Self-directed learning is only applicable at university.

Because university teachers don't always push students to learn like middle school teachers.

The attitude towards learning depends entirely on the students' self-awareness.

Establishing a competitive relationship makes it easier to mobilize students' enthusiasm for learning.

So Gu Lu felt that it was necessary to set up several competitive goals for everyone.

Gu Lu looked at the first row in front of him, "Zhengxuan, can you keep up with the progress of my lecture just now?"

Ma Zhengxuan nodded, "Yes." ”

Then he looked at Bai Yao, "Bai Yao, what about you?"

Bai Yao said with a smile, "It's easy, it's not that difficult." ”

In the end, Gu Lu's gaze fell on Bi Qi, "What about you, Bi Qi?"

Bi Qi shrugged his shoulders and looked relaxed and casual, "This part is such a basic content, I want you to skip it directly, no need to talk about it." ”

Bi Qi deliberately raised his voice, "Don't say that you are speaking at the current speed, even if it is ten times faster, I will not have a problem at all!"

Class: "......"

Gu Lu had a black line.

Gu Lu wanted to comment, saying that Bi Qi was very poor, which was both deliberate and exaggerated.

But when I think about it, this is in class, or let's talk to Bizzie after class.

Gu Lu coughed lightly and pulled everyone back from their speechless thoughts to Bi Qi, "I'll go on, the progress will slow down a little, everyone listen carefully, do a good job of preview after class, the next time I go to class, I will return to the original rhythm, you guys be mentally prepared." ”

After speaking, Gu Lu opened the textbook and talked about the second chapter, the limit of the sequence.

It is also one of the three core contents of the number.

…………

The two lessons are completed.

After Gu Lu assigned a few homework assignments, he walked out of the classroom with his bag.

"Teacher, wait for me, wait for me. Behind him, Bi Qi chased after him.

"Will there be any classes later?" Gu Lu raised his eyelids and asked.

Bi Qi scratched his head, "No, there are no classes in three or four periods, and there is only one senior substitute class in the afternoon in five or six periods." ”

"Teacher, I want to ask ......"

"Ask me why I'm here, and have I become your number teacher?" Gu Lu smiled.

"Uh...... Be. Bizzie replied honestly.

"The reason is very simple, Yan University is my alma mater, and I will definitely choose to teach at the university. Gu Lu explained while walking side by side with Bi Qi, "As for the fact that it will teach you a few lessons, I think it should be a coincidence." ”

"What is the coincidence......" Bi Qi stood in place, frowning, feeling that things were not so simple.

But he found that Gu Lu had already walked away, leaving only a back, and hurriedly trotted after him.

Downstairs, walking out of the teaching building, Bi Qi found that Gu Lu was not walking in the direction of the Hui Shu Yuan building.

"Teacher, aren't you going back to the office?"

"I still have classes in three or four classes. It's not just about teaching your class a math lesson. ”

"What class?"

"High Numbers!"
