[editor by] with the launch of the 4th higher school teacher award and the 2008 national masters curriculum, a large number of first-class courses and lecturers emerged. This time, the ministry of education of the north, together with the ministry of advocacy of the party commission, launched a special column entitled " a curriculum for teachers and fine people " , which seeks to write about the great names of teachers in the north and to show their charm. This is a recording of the master's face, engraved in the style of the scholar, and here is the great wonders of turning around, and the gilded vagaries of the ancient world... Let's come closer to these famous lessons, to these famous teachers, to them, to the sea of knowledge, to the world of spirit。
On the side of the “three-foot platform”, they do their duty and are not tired; on the season of the “tori fung,” they are in the valley of vanity and joy; and when the “book says”, they are left alone and do their research。
We are eager to listen to their teachings: china's historical geography, which allows us to travel through the south of saibei and the black waters of the white hills, bathing in the winds of tang dynasty and rain of song dynasty; calculus, which allows us to enter the temple of mathematics and enjoy the pleasure of reason; modern chinese literature, which guides us in the name of muss, which allows us to experience the pulse of the times and explore the true nature of humanity; economics, which allows us to understand the economic principles behind the complex phenomenon of the market... Every fine talk that opens us up and benefits us from it; and every communication from a close distance makes us twisher, like a spring wind。
Accurate analysis, clear logic, let us know what science is; a sober analysis of the world, a precise judgement of the times, gives us a sense of reason; and the light-winded statement that graceful and light commentary reminds us of what is thought. They taught us, not only the knowledge of the world, but more than that, we opened up a wonderful academic temple。
Independence of thought, the pursuit of truth, in the path leading to civilization, with the courage of intellectuals to assume their responsibilities; to take positions, to be clear, to be good, to be committed to their own actions and to be told; to repair, to be all-powerful, to govern, to be all-powerful, to be all-powerful, to be all-powerful, to call upon us again and again . . . . . . . . They gave us not only the ability to survive and develop in the past, but more the power of personal charm。
And they smiled, and they covered the master's breath, and they threw their hands up and led a generation of learned men. “a few springs and autumns are full of fragrance, and two dots become frost, and the garden is filled with plumes, and the sky and the earth are wide from three feet.” they, confined to a three-foot platform, danced the most magnificent of life; they, with their dumb voice, conveyed the most wonderful language in the world; and their pristine language, their low-key style, and the kindest style of apt academic, sufficient to allow generations to learn the finest。

Quantum mechanics: keeping pace with the times
Classroom 331 of the great north electronics, where the students listened with great attention to the fact that the teacher on the podium was wearing a black vest, an old flower glasses on his nostrils, a textbook with his hands, and he was showing the experiment with a skillful ppt, and at the same time carefully and carefully on the blackboard. He's got a clear idea, a live talk, and he's making the original quantum world interesting. This is what professor cheng hinsen of the north university of physics said about the classroom of quantum mechanics。
Recently, in the 2008 national quality course, evaluated by the ministry of education, prof. Cheng honsheng was named on the list of quantum mechanics. Quantum mechanics is an important subject in physics education, as well as in other arts and sciences. Many students in science and technology have been told that life is incomplete because they have not studied quantum mechanics before age 25. However, in the course of practical learning, a completely different perspective of quantum mechanics and classical mechanics makes it difficult for many students to accept it. So, what is the beauty of quantum mechanics that prof. Cheng honsheng talks about, which most people find difficult to understand
"let's keep the curriculum up to date."
The interview was about one night, when we were wondering if we might be late for dinner, and he smiled and told us that it was his habit to work in the office at night. A computer, a desk, a book cabinet, a white wall, the first impression of an office is simple and neat. A large blackboard is particularly visible around the white wall, where co-mingled equations are visible. "i write on it anything that comes to mind," he smiled and said。
When it comes to the design of the master course "quantum mechanics", cheng teacher has repeatedly emphasized the words "closer times". He said, “quantum mechanics is a fast-growing discipline, and many modern physical instruments, such as scanning through microscopes, have applied the basic principles of quantum mechanics, which solve many of the problems that we were afraid to think about before, and of course our teaching should keep up with the times.”
“let's keep the curriculum up to date” is the long-standing teaching philosophy of cheng teacher. In his view, quantum mechanics is a very fast-growing subject, “the content of teaching materials can only be kept up to date so that students can truly learn at the forefront of international development”. At the same time, however, he agreed that the content was being updated for teaching purposes and that the new content must be conducive to a better understanding of the curriculum and basic content。
The question of how to bring students deeper into the world of quantum mechanics, so that they can do more in their futures and in their studies, is a question that has always been the subject of reflection by an old professor who has worked tirelessly on teaching. As a result of the short school hours, the classroom teacher combines the classroom with the extracurricular lecture to “maintain the best basic part in the classroom” and to increase the extracurricular learning time by, inter alia, holding lectures, so as to enable students to acquire better knowledge, both in terms of strengthening the foundation and opening their horizons, and to increase their interest in learning。
“accompanying the times” and “basic-focused” are mutually reinforcing, bringing both vertical and horizontal depth to the curriculum of the programme teacher. “i hope that the students will benefit from this course, and that they will learn, while learning, a new intellectual approach that can move out of the classical physics framework, think in a broader context, expand their thinking and enhance their ability to solve problems, and build confidence in themselves.”。
When it comes to how quantum mechanics is becoming a fine subject, it is thanks to the teaching and research team, which has a great team of teachers. “becoming a quality course requires years of effort by such an excellent teaching team, people laid the foundation, people inherited and developed, and i was just a man of responsibility.”。
"communication with students is a pleasure."
In the course of the course, he shows his breath, and when he speaks of his joy, he shakes his arms and smiles; in answer to questions, he has a good sense of speech, a serious tone, and a single piece of writing on the blackboard is clear. And when we were interviewed in the office, professor cheng was more like a loving grandfather。
"i like to discuss issues with students, and i benefit from sharing them." teacher cheng particularly likes to be with students, who are friends and his students like to be friends with the old professor. Whenever students ask some good questions, they write them down in time. He felt that none of these teachers had come to terms with the problem and that students' understanding of knowledge was best advanced. It is in this interaction, where students have deepened their understanding of quantum mechanics, and where lesson teachers have received feedback in time to better complement the curriculum, “to create a good circle”。
"i like to take classes with young people, and i feel full." when it comes to his students, cheng always laughs, "but i really feel responsible because they're very good kids." for these excellent children, the best efforts are made by cheng teachers in the classroom。
In his classroom, every lesson was done by him himself, and each course had many versions, and he had always done everything he could to teach him what he knew. On mondays and wednesdays there is a course on quantum mechanics, which he will use throughout thursdays and fridays to constantly modify in his office; he will re-examine his own curriculum before each course; after the course, he will re-assembly the contents of the course with his thoughts and problems. “the preparation of lessons must take time and not mislead the students”, he stressed, “quantum mechanics and theoretical mechanics are completely different frameworks, making mistakes with little attention, rather than teaching them
“it is true that the students of the great north are very smart, but i have often told them that they are encouraged to step up, but that they cannot rely on their intelligence to do nothing.” teacher cheng introduced that, because quantum mechanics is a more difficult subject to study, in his classroom he will also take care to balance the differences between students on different bases. “i will add something to the discussion in the case of good students, but i have the same general principle for students, that you should appreciate the opportunity to study well when you enter north china.” in the discourse, there is an infinity of love and hope for students。
Teacher's life: the mind is always young
When you listen to your own story, you're always clearly aware of a big north complex. When talking about his teachers, about his deep feelings with the elders, about his experience of doing research as a graduate in the north when he was young, we can all read the memories in the eyes of his teachers。
Speaking of his students, mr. Cheng is proud again. After graduating, he recommended at least 1,200 students who either stayed in top-level laboratories for research, went to multinational enterprises, returned home to continue to participate in research and made many achievements in different jobs。
“the majority of north lords will have a bond, and we should make full use of our natural advantages to attract them back to the north and contribute to the creation of the world's leading university.”
Speaking of love with the north, mr. Cheng came to us, and in his conversation we seemed to see that big north spiritual tree with its strong roots and thick branches. The old northern teachers, like cheng, are like the thickest catheters of this tree, passing on and feeding the new generation。
It's hard to talk about it, it's good to laugh, it's very contagious, and it's hard to imagine that a man so dynamic is 71 years old this year. In the face of the journalist's lamentation, mr. Cheng laughed, saying that he had always focused on exercise. He insisted on going to the east playground every day at a fixed time, and he never stayed up in the night "drives," which is probably the most vivid interpretation of "one hour per day, 50 years of healthy work." and "i've always been with young people," and "this is the effect of the environment."
We are grateful for the ease and rigour with which scientific teaching is conducted and the freedom of life outside the classroom. It's not just a magical quantum world of change that is brought to students by humans, preachers, and teachers of cheng honolulu, but also a splendour tree that inspires us forward。
