"Inertial forces, laws of thermodynamics, grating diffraction experiments, induced electric fields, Millikan oil droplet experiments, special relativity, gravitational waves..."

　　College physics, a compulsory basic course for science and engineering students, is often affectionately called "big things" by students, and a physics experiment report has become a classic memory in college life。University physics has established the basic concepts, basic ideas, basic laws and basic methods of physics, which have become the basis for university professional course learning and scientific and technological innovation activities。

　　Over the years，Beijing University of Technology，The word "big thing" is often mentioned.，Students always share their feelings like this: "Deep and simple theoretical explanation，Vivid and intuitive demonstration experiment，Rich and interesting teaching cases..."，Behind every wonderful class，In fact, it is inseparable from the Beijing Institute of Technology physics teaching and experiment team in order to cultivate first-class talents。

The "big things" lesson of "three requirements"

　　"We learn physics in high school, why do we need to learn it in college？Although it is still mechanics, heat, optics, electromagnetism, etc., compared with high school physics, the depth and breadth of university physics are greatly expanded, and the content is more comprehensive and accurate, so that students "deja vu" university physics is often "slow to get started" and "difficult to get started".。"Students have been used to the ideas and methods of dealing with special or simple physics problems learned in high school, and when they come to university, they will feel very uncomfortable when they are exposed to college physics based on advanced mathematics, calculus, and vector operations.。Professor Hu Haiyun, head of the physics course at the North University of Technology, explains the key。

　　"Although such a transition is a challenge, as long as the difficulty of the course is reasonably arranged, the logic is strong, the example problems and exercises are in place, and the textbooks are highly matched, the fast introduction to college physics is not so difficult.。As the leader of the university physics teaching team, Hu Haiyun, who has been teaching in Beijing Institute of Technology for more than 20 years, not only has rich teaching experience, but also has an international vision and innovative spirit。Under her leadership，This university physics teaching team of more than 30 people has always maintained a spirit of unity and struggle and the vitality of innovation and inclusiveness，There are 3 winners of Beijing University Teaching Teacher Award and 1 winner of Beijing University Young Teaching Teacher Award，It is also the team that has won the most T-more classroom teaching excellence awards in our school。

　　The excellence of the university physics team is ultimately reflected in the effectiveness of talent training。How to be student-oriented, let students quickly break into the world of university physics？After many years of teaching practice, the teachers of the physics teaching team of Beijing University of Technology have gradually condensed their own "three demands" teaching philosophy, that is, seeking truth, living and novelty。

　　Realistic, solid and rigorous, contact with reality。"There is a risk of dust explosion in warehouses where chocolate raw materials used in the production of cookies are stored, which is caused by the ignition of powdery raw materials through electrostatic discharge (sparks) accumulated during processing, transportation and storage。So, where is the location of the dust explosion in the dust explosion accident caused by static electricity？Can an electrostatic discharge (spark) from a worker cause an explosion？The scene is abstracted, and then the model is established, and the conclusion is drawn by analyzing and calculating the electric field intensity distribution, potential distribution, and electrostatic energy stored by the human body generated by the static electricity of the chocolate powder transported by the pipeline, which is a teaching case about electrostatic field in the university physics class。Here, abstract theorems and formulas are translated into real daily life。

　　The college physics course of Beijing Institute of Technology not only focuses on the teaching of basic knowledge such as physics concepts and laws, but also actively builds a teaching model for the purpose of ability cultivation, and explores the teaching practice of explaining principles from practical application and then returning to application。"What do you mean by coming from reality and going to reality？Starting from cases in life, we gradually explain the principle. In addition to mastering physical knowledge, students also understand where dust explosions are most likely to occur and how to prevent them。"University physics young teacher Li Jungang introduced。

　　Live, scientific method, flexible。Mechanics and heat, vibration, wave and optics, electromagnetism and modern physics, these are the four modules of university physics courses for non-physics major science and technology students。"In addition to dividing the four modules, we also divide the course into A and B levels according to the number of knowledge points and the degree of difficulty, and then combine a variety of length courses, so that we can provide flexible choices for different training needs of majors.。"Hu Haiyun said。

　　It is under the guidance of the concept of "living" that the college physics exam is also divided into two modules for assessment and scoring by module. The original intention of this design is that if a module fails, students only need to retake a separate module in the future, and the other module scores can be retained。In this way, students can not only achieve learning results, but also reduce the pressure of learning。

　　Seek new ideas, change ideas, and constantly innovate。"Big Things" is an ordinary "old course", but it is full of innovative vitality in Beijing Institute of Technology。Since 2008, it has been rated as the best course in Beijing，The university physics teaching team not only undertook to complete more than 20 various teaching reform projects，An interactive teaching system based on Clicker is also developed，Offer all English university physics courses, MOOC, SPOC, etc，iCourse, a new form of teaching material for university physics, was published，Innovative use of mobile apps in classroom teaching。

Creating a "high-tech" College Physics "New Classroom"

　　"How to cultivate students' interest in physics and truly enter physics is our most important, so we have been willing to try the freshest teaching methods to teach this physics class well.。"Teacher Hu Haiyun said。

　　In September 2014, the "Big Thing" of Beijing Institute of Technology opened its own "Internet +" era, and the university Physics MOOC was officially launched, which has become a good helper for students of Beijing Institute of Technology to learn college physics。"The MOOCs, which cover everything and can be watched over and over again, are the efficient way I want to learn。Major, a student of the School of Information, spoke his heart。

The main teacher team of University Physics MOOC of Beijing Institute of Technology

　　In 128 class hours, a total of 4555 minutes of college physics MOOCs behind，It was six teachers working hard for months，Course recording, post editing, subtitles, video courseware upload, etc，They don't know anything about these techniques，With a fighting spirit for the cause，Day and night，Finally won the "battle"。"I remember that a few days a month did not sleep, time is tight, can only work overtime.。"Electromagnetism and modern physics part of the MOOCs teacher Miao Jinsong recalled。Since then, university physics courses have further deepened their use of MOOC resources, so that they account for 16% of the course scoring assessment, and for repeat students, the proportion of learning through MOOCs has reached 50%。Moocs have become an essential part of physics teaching at Beijing University of Technology。Since the summer vacation of 2016, the university physics teaching team has completed the production of a supporting MOOC "Analysis of Typical Problems in University Physics", with a total of 455 videos totaling 3,150 minutes。

The new form of University physics textbooks of Beijing Institute of Technology

　　From scratch, to build a complete online MOOC course, the "big thing" teachers of Beijing Institute of Technology did not stop there。How to make MOOC and classroom teaching more closely combined to improve the quality of talent training, this pursuit has never changed。Then, a new and more innovative iCourse was born。"This set of four volumes of textbooks is written entirely on the basis of MOOC, and the questions and materials in the book are printed with two-dimensional codes, and if you have questions, you can scan the code and have the teacher's recorded answer.。So wherever students are, as long as they have books and the Internet, they can study by themselves or review at any time。"Teacher Feng Yanquan said。The new form of teaching materials not only surpass the general paper teaching materials, but also avoid the fragmented learning problems that may occur in online learning, so as to truly make the teaching materials "alive" and guide students to use online resources as the media。

　　Innovation "again and again", the university physics of North Technology also opened the "flipped classroom" and "rain classroom" innovation exploration。In the "flipped classroom" experimental class, students mainly learn MOOC, and the classroom becomes a "stage" for them to actively share their learning results, which greatly releases the potential of MOOC。"In order to complete my explanation in class, I really actively put more energy into learning, and my understanding of knowledge became deeper.。"Participated in the" flipped classroom "classmate Xu Chen recalled。So far, the average final grade of the students in the two flipped classes is 84.8和86.1 point, not only higher than the average score of the ordinary class, but also the proportion of high level students is much higher than the ordinary class。The introduction of the mobile APP "rain class" into teaching is the latest innovative exploration of university physics。"The teacher pushed the exercises and courseware to us through the 'rain class' before class, the 'rain class' can also scan the code and sign in, the 'rain class' can answer the questions in real time and feedback the results, and we can also interact with the bullet screen, which made me feel an unusual learning experience.。Li Jing, who has used the "rain classroom" to learn, shared his feelings。

　　Hard work has yielded fruitful results。The "College Physics" course of Beijing Institute of Technology was not only selected as the first batch of construction courses of the "Chinese University MOOC" platform of the Ministry of Education's Love course and the first batch of independent mode MOOCs of "Xuetang Online"，It is also widely recognized，Number of online course enrolments per module of the course，The cumulative average has reached more than 60,000 people，More than 400 universities are involved。In addition, "The beauty of Physics to see" flowers "is also rated as the national quality video open course," College Physics (First, second) "is rated as the Beijing higher education quality textbook, the new form of iCourse textbook published by the Higher Education Press, is also the only set of university physics MOOCs new form of textbooks。

Physical experiments, with inspiration to cultivate the seeds of innovation

　　Physics is a discipline based on experimental foundations and faithful to experimental data。Theory comes from the summary of experiments, and only learning theory without doing experiments is equivalent to "talking on paper".。Speaking of the "big thing" of Beijing Institute of Technology, physics experiments are indispensable。

　　At the Liangxiang campus of North Technology，Is located as Beijing municipal experimental demonstration center physics experiment center，Established in 1999, the center now consists of six laboratories: the Mechanics Laboratory, the Electromagnetics Laboratory, the Optics Laboratory, the Modern Physics Laboratory, the Demonstration Physics Laboratory and the Innovative Open Laboratory for University students，It undertakes the teaching tasks of "University Physics Experiment" and "Modern Physics experiment" for applied physics majors for more than 3,000 undergraduate students of science and engineering majors every year，In addition, it also provides an innovative research experiment platform for undergraduates，More than 220,000 student experiment hours are completed each year。

　　In the course of teaching, the Physics Experiment Center has gradually formed a new model of "two-goal, three-stage" first-class talent training, which not only strengthens the basic practical ability training and scientific literacy training, but also attaches importance to the innovation ability and academic quality improvement of top-notch talents。"The 'two goals' are to cultivate students' academic character and academic ability, and the' three stages' refer to classroom teaching, the cultivation of innovative ability and in-depth scientific research frontline exercise to enhance scientific research ability.。Liu Wei, head of the physics experiment course, explained it this way。

At the beginning of this semester, the optical experimental group teachers prepared lessons collectively

　　As a college physics teacher engaged in experimental teaching, it is a basic requirement to practice solid basic skills. Before taking the post, teachers must personally operate more than 30 kinds of instruments and equipment, and master the use methods, characteristics and common problems。Every semester, all the teachers of the experimental course will make three collective preparation for lessons according to different module experimental groups at the beginning of the semester, in the middle of the course and before the end of the class. Each time, they will give a trial lecture to discuss the problems encountered in teaching, which also provides the best opportunity for young teachers to observe and learn。"When preparing lessons, experienced teachers often emphasize that guiding ideas should also be brought into daily experimental lessons.。Dou Lingyu, a young teacher who has not long entered teaching, felt deeply。

Teachers from the Physics Experiment Center visited the classroom teaching of physics experiment at ANU

　　In order to get rid of the rigidity of asking students to repeat the set set experiments all the time, we should cultivate students' ability of independent experiments and innovation。The teaching team of the Physics Experiment Center is also actively benchmarking world-class universities, setting up semi-open experimental projects, without setting experimental plans in advance, only giving experimental equipment and experimental topics, allowing students to design experiments by themselves and then complete the experiments。

　　As an "old comrade" trained by the physics Experiment Center system，The experience of Wang Baochu, a 2015 physics student, is typical，She excelled in physics experiment courses and has a special interest in experiment，I signed up for the 2016 Beijing College Students Physics Experiment Competition，Inspired by teacher Lu Changhong of the Center，Wang Zhengchu cleverly applied the laser to the traditional moment of inertia tester，An experimental instrument was invented to measure the acceleration of gravity on Earth，Not only won the first prize of Beijing college students physics experiment competition，Also under the encouragement and guidance of the center's Shi Qingfan teacher，Published a domestic core journal paper。之后，She became interested in the refraction of water waves，Once again, Shi Qingfan encouraged her to dig deeper，The experiment of "water wave prism" is designed，The research results will be submitted to the American Journal of Physics (AJP).，It has been accepted into the modification phase。"Since my sophomore year, I have been doing experimental projects in the Physics Experiment Center, and I have received a lot of support from the teachers in the center, whether it is competitions," Big innovation "or publishing papers。I benefited a lot from the inspiring guidance of my teachers。"Wang said。

　　It is under the long-term hard work and hard work of the teachers in the center，In recent years，The physics experiment center is fruitful，Approved national virtual simulation experiment teaching center，Won the first prize of "National College Physics Basic Course (experimental course) Young teachers teaching competition"，"University Physics Experiment Course" was rated as "Beijing Excellent Course"，Won the second prize of Beijing Higher Education Teaching Achievement Award，He guided undergraduate students to publish 56 papers as the first author，He won 15 awards in the national college student innovation competition，Beijing level award 50。   

　　"University Physics" and "University Physics Experiment" is one of the largest public basic courses in our university, which plays a decisive role in the training of science and engineering talents。University physics and experimental teaching team，For a long time, we have been adhering to the mission of "morality, responsibility, love and struggle"，With a high sense of responsibility and dedication, innovation and tireless work，On the three-foot platform bearing fruit，Has made an important contribution to the school talent training!Future，The college will take the construction of "double first-class" as the goal，We will continue to intensify our work，Continue to gather and train first-class teachers, and constantly consolidate and create first-class results，Strive to make greater contributions to the training of first-class talents in the school!"Said Jiang Yan, secretary of the Party Committee of the physics Institute。

　　In 1940, the Academy of Natural Sciences was founded in Yan 'an, and physics became the "open door" course for the founding of the school。Over the past 78 years, University physics has made an irreplaceable contribution to the learning and growth of generations of BEili workers。

　　In the new era, with the development of the school, the university physics teaching and experiment team has always adhered to the quality, pioneering and innovative, and has struggled tirelessly!

　　I'm on the road all the time!
