In this "Quantum Mechanics" class, the teacher talked about the theory of quantum mechanics of superconductivity, and he lectured vigorously, speaking quickly.

Some students looked confused, and some students understood or partially understood.

The diligent and inquisitive student asked in class, "Teacher, why is the trapped magnetic flux always an integer multiple of 2πћ/q?" Teacher, can you explain to us the Schrödinger equation in the classical case?

The teacher answered immediately, but his answer did not completely dispel the student's doubts.

Some students don't know how to pretend to understand, and some students break the casserole and ask the end.

"Actually, it's all written in the textbook, you can study this issue in depth after class, the time is limited, let's go into the following teaching. "The physics teacher seemed to be in a hurry, and he would only answer any question once, not a second time.

When the bell rang for the end of class, the physics teacher flashed and disappeared in an instant.

Honest students stay in the classroom to study on their own and digest important knowledge points.

The playful student complained that "this class is equal to nothing", so he left the classroom in twos and threes to have fun.

In the next few days, Shen Qi listened to a few physics major classes, inspected all corners of the campus, and went to several surrounding colleges and universities for private interviews, and summarized several main problems to feedback to Academician Shi:

1. The teacher teaches rigorously and seriously, but the student attendance rate is low, especially the "Methods of Mathematics and Physics", the attendance rate is only 17.3%, the reason is that there is less interaction between teachers and students, and if the courses with strong theory are taught according to the textbook, students will lose their enthusiasm for learning over time.

2. When students encounter problems that they don't understand, they don't know who to ask, and teachers basically don't interact with students after class.

3. Our institute subscribes to internationally renowned physics journals such as PRL and PT, but undergraduate students do not have access to these, and only graduate and doctoral students have the opportunity to read them.

4. I interviewed several senior students of the School of Physics, and they said that their graduation thesis design is very watery, and the water is water, anyway, the tutor said that as long as the graduation thesis is written in the standard format, they will definitely graduate. This worries me.

5. In terms of scientific research, we did not go deep into the project teams and laboratories, and through the paper inquiry, it was found that our institute published hundreds of physics papers last year, but the homogenization phenomenon was serious, and it was more common to write papers in order to complete the task.

6. Students reported that the food in our school cafeteria was too unpalatable and expensive. In order to improve the diet, a male student majoring in physics installed high-power electrical appliances in the dormitory to cook pork, chicken, beef tendon balls and other foods, which almost led to a fire, which has great potential safety hazards.

......

After reading the summary of Shen Qi's problems, Academician Shi was dignified: "Shen Qi, you hit the nail on the head and said that our common problems, 1 and 2 we have been trying to improve, requiring teachers to strengthen interactive communication with students, pay attention to the link of solving doubts, but the effect is not ideal, as you said, students encounter problems that they don't understand after class, and they don't know who to ask for advice." Some teachers don't see anyone after class, let alone the students, and even I can't find them. ”

Shen Qi said: "I think that the importance of our college and our university to undergraduate students is relatively low in the whole university town, and the best ones are Southern Normal University and CUHK. Only when the education level of undergraduates in a university has gone up can a university be truly worthy of the title of a prestigious school. The reason why Princeton is strong, their undergraduate level is equivalent to the graduate students of most colleges and universities in the United States, which is closely related to the resources and importance invested by the school in undergraduate education. ”

"Shen Qi, do you have any specific suggestions?" asked Academician Shi.

Shen Qi offered advice: "Princeton's kind of undergraduate tutorial system is not an overnight achievement in Chinese universities, not to mention that we will talk about the Southern Normal University next door, their teachers will have a fixed Q&A time every week, and take the initiative to establish a WeChat group with students, which has been well received by students." In terms of undergraduate teaching, we can learn from the successful experience of Southern Normal University, and add a provision that students' evaluation of teachers should be included in the annual evaluation index of teachers. ”

Academician Shi immediately made a decision: "I fully accept this suggestion and implement it in the Institute of Physics first." As for the subscription rights of professional journals to undergraduates, the low quality of the papers of our researchers, and the formality of undergraduate graduation projects, it will also be solved in the future, which will take some time.

"Regarding the problem of unpalatable food and high prices in our canteen, I will truthfully report the situation to the vice president in charge of logistics...... To tell the truth, this canteen contractor did a very good job last year, and it was too much worse to buy a porridge with pickles and pork bones, which was full of pickles and no pork bones. It seems that Academician Shi has also eaten in the canteen, and he also complains that the newly signed canteen contractor only cares about making money and has no conscience.

This kind of problem has existed for a long time, and it is not so easy for any university to solve it.

That is, Shen Qi's fame is great, and the academician of the time has the intention of reform, and the two hit it off: change it later, and it is very good.

As a distinguished professor of the School of Physics of Nangang University of Technology, Shen Qi volunteered to take the lead in the study room, answering questions in all fields of physics for all undergraduates of the School of Physics.

Academician Shi thanked Shen Qi for his kindness, Shen Qi made a good start, who would dare to disobey the other professors and lecturers of the Academy of Physics?

The news spread quickly in Nangang University of Technology.

"Shen Qi, the big man of the Philippine Award, sits in the academy to answer students' questions!"

"Why did the big guy of the Philippine Award go to the courtyard?"

"Shen Qi is a distinguished professor of our institute of physics. ”

"He still knows physics?"

"He's a big guy who has published physics papers in PRL and Science!"

"Niu, Shuangxiu boss, let's go, go and say goodbye to the boss!"

The students of the School of Physics rushed to tell each other, and on the first day of Shen Qi's Q&A, the study room was full.

Because there were too many students who came to teach, Academician Shi specially arranged a teaching assistant to assist Shen Qi.

Teaching assistants collect students' questions and rank them, with the most frequently asked and most difficult to understand questions answered first.

The enthusiasm of the students was high, and in just one hour, they asked hundreds of questions, which were sorted into ten common problems and two special problems after being sorted out by the teaching assistants, covering almost all the core courses of undergraduate physics majors such as classical mechanics, quantum mechanics, electrodynamics, optics, thermal, and mathematical physics methods.

"Okay, please be quiet, and I'll answer everyone's confusion one by one. Shen Qi found that it is not that college students do not like to study and are not good at thinking, they are all good students with an active heart to study, and what is lacking is an academic atmosphere with full participation.

"The number one problem is the solution of the Schrödinger equation, OK, so let's start with the Schrödinger equation. ”
