　　At that time, the needle passed 12 midnight, and the campus was silent for another night。

　　An octogenarian and a group of young students walked out of the teaching building, accompanied by the road, still kept discussing the problems in the experiment。It is the end of the day and the beginning of a new one。

　　This scene is played out every day on the campus of Beijing Institute of Technology。The figure of the old man has "maxed out" the circle of friends of the teachers and students of North Li。The teacher who accompanies the students to study every day is the 84-year-old professor Zhang Zhonglian, founder of the photoelectric Innovation Education Experimental Base of Beijing Institute of Technology。

　　From Qingsi to Huafa, he grew up in the campus of Beitech, taught here and cultivated people, and deeply cultivated the education cause of first-class talents. So far, he has been accompanied by Beitech for 63 years。

　　In the 63 years of Beijing Institute of Technology, Zhang Zhonglian's choice of life direction is related to the words "national needs"。

　　In March 1952, the former Ministry of Heavy Industry of the Central People's Government issued a document to adjust the educational direction of Beijing Institute of Technology (the predecessor of Beijing Institute of Technology) to serve the construction of national defense industry. Since then, Beijing Institute of Technology began the journey of building the first national defense industry college in New China。

　　In 1956, 21-year-old Zhang Zhonglian was admitted to the tank manufacturing major of Beijing Institute of Technology from Xiong Yue High School in Yingkou, Liaoning province。In this institution of higher learning, which trains "red defense engineers", Zhang Zhonglian started his college career。Soon after entering the school, according to the needs of national defense construction, he and more than 200 other students transferred to the radio department radar major。

　　In April 1960, Zhang Zhonglian graduated early and stayed at the school to teach。He took rocket instrumentation and sensors as the direction of teaching and research, and was responsible for the construction of related laboratories。However, in September 1962, he once again changed the direction of scientific research due to the needs of the country, and began to study night vision technology and photoelectric imaging technology。From tanks to radios, from rocket instruments to night vision technology, Zhang Zhonglian said: "As a northern Li worker, the needs of the country, the needs of the Party is my choice.。”

　　After nearly 40 years of dedicated work, Chang Zhonglian, transformed by the needs of the country, retired in 1995, and a new journey began。

　　Ten years before Zhang retired, the Beijing Institute of Technology began to implement teaching reforms to improve students' practical skills。According to the requirements of the school, Zhang Zhonglian opened the compulsory course "Experimental Technology of Instrumentation Electronics" for the whole department, "this course should be regarded as the predecessor of the later photoelectric innovation education experimental base".。

　　In 2000, the Beijing Institute of Technology granted a special grant of 150,000 yuan to support Zhang Zhonglian to establish the "photoelectric Innovation Education Experimental Base", hoping to build a new model of practical education that trains students' practical innovation ability and improves students' scientific quality across majors。

　　After several years of accumulation and construction, under the leadership of Zhang Zhonglian, the experimental base quickly played a supporting role in talent training。"While establishing the best knowledge structure, guide students to gradually establish the best intelligence structure, and lay a good foundation for practical ability through experimental electives in the early stage of undergraduate study;In the later stage, through the two very important teaching links of graduation practice and graduation project, we can comprehensively apply the knowledge we have learned to solve practical problems。Zhang Zhonglian has also established a set of teaching models to guide students to innovate and cultivate。

　　"You could say we built this system with our students。Whenever summarizing the teaching mode of the base, Zhang Zhonglian always upholds the concept of teachers and students and teaching and learning。"My students are my teachers。What to teach, how to teach, and ask students for their opinions。Chang Zhonglian often said, "Innovative education does not need to debate, put your method out, let students go to the factory, the laboratory to test.。”

　　This student-centered teaching method is inherited from Zhang Zhonglian's time at the Beijing Institute of Technology。At university, Chang was a "shoulder-shouldering student leader"。"At that time, I was the deputy minister of the life department of the Students' Association of the university, and I had to take the lead to help the general affairs department。In this way, student work inevitably eats into his study time。Thanks to the school's study group system, Zhang Zhonglian has not fallen behind in his studies。

　　At that time, Zhang Zhonglian was in a team of three people. Every night, everyone would summarize the day's activities, changes in thinking and problems found, and then propose improvement measures to each other。These "learning friends" later became close partners who helped each other in the development of his career。

　　Now, as a teacher, Chang always teaches his students: "Joining several teams and groups is very important in growth and development.。"After working in detention，Chang also passed on the method of "setting up learning extracurricular activity groups"，In and out of the classroom，Chang often organizes students，Encourage people to work in small groups，Research a project, a problem，Discuss with each other and review old ideas，Cultivate a sense of teamwork，Improve learning quality。

　　When Zhang Zhonglian was a student, the teacher he most admired was Li Kuan, a teacher at the radio department of Beijing Institute of Technology。When Li Kuan gave the class to his students, his lecture ideas were clear and his knowledge system was detailed. He not only asked the students to take good notes, but also paid great attention to writing on the board. After one class, the blackboard almost became a "white board".。

　　"Li teacher is strict with students, careful and responsible for work, always student-centered, explore the characteristics of each student, so as to carry out targeted teaching.。Zhang Zhonglian benefited a lot from such words and examples, and the "student-centered" way of teaching was deeply rooted in his heart。

　　It's been 19 years since the experimental base was established，Students who have done innovative practice under the guidance of Chang Zhonglian，People who always refer to themselves as "Base"，"The base is able to break the existing classroom teaching model，Stimulate students' hobbies and interests，So that we can learn independently，And we are motivated by participating in the competition，I have put what I have learned into practice。There are teachers who are willing to contribute, do not care about personal gains and losses, they are single-minded, down-to-earth knowledge, set an example for the students, under the influence of the base environment, we become practical and sincere, know how to work together, not only enrich the knowledge, the world view, the outlook on life has been shaped。Wang Benxin, a graduate of the class of 2008, recalled Zhang Zhonglian's words and deeds。

　　"Only let students passively accept, it is impossible to cultivate innovative talents, I encourage students to let go to create, which is the key to the success of the base.。Zhang Zhonglian summed up a set of practical training mode: in the classroom，The teacher first explains the knowledge systematically，Then guide students to practice modules，Finally, students write a summary report to deepen memory learning;And extracurricular activities，Let the students practice first，Make a model that is similar to the desired purpose，Then the teacher intervenes，Give targeted guidance。

　　Photoelectric innovation education experimental base since its establishment in 2000，Cultivate a large number of outstanding students with outstanding innovation ability，He has won provincial, municipal and national teaching achievement awards for many times，Won gold and silver MEDALS in the "Challenge Cup" National College Students Extracurricular Academic Science and Technology Works Competition, National College Students Mechanical Innovation Design Competition, National College Students Photoelectric Design Competition and other innovation competitions，fruitful。More than 10,000 students have exercised and grown here, and the photoelectric innovation education experimental base has become a sign of the school's innovative practice and education。

　　In 2016, a "news feature" with only 531 words, titled "In the Beijing Institute of Technology, there is a light called" 4002 at 11:00 in the night ", was published on the Beijing Institute of Technology News network, and it was clicked more than 10,000 times in a short time。It created a brand new vocabulary for BEIT -- "4002 lights".。

　　The article wrote, "The information teaching building at 11 o 'clock in the night, the other classrooms have long been silent, and the lights of 4002 are still on.。4002, no different, nearly 300 square meters of area, 258 seats, 108 lights, it is just an ordinary one of the six lecture halls of the information teaching building;4002, really different, every midnight, there are still more than 100 students here to stick to the midnight fight..."

　　The light of 4002 is the light of Room 4002 where Jang Chung-yeom, who is in his 80s, keeps watch every day for his students。This seemingly ordinary act, he has maintained for more than 10 years。Every night in the campus, there is almost the figure of the old man。

　　Before the photoelectric innovation education experimental base makes teaching plans every semester, Zhang Zhonglian will talk to students, listen to the needs of students, and then formulate the teaching content of the base accordingly。Every semester, the class time of the base is repeatedly coordinated by Zhang Zhonglian, and strive to ensure that every student who chooses courses does not have a conflict in the class schedule。Sometimes students miss classes because of illness, and he will carefully arrange the base teacher to make up for the lessons。If energy permits, Zhang Zhonglian will personally review each homework, and will gather excellent homework into a book for the next class of students to refer to。

　　Mr. Chang, who has been retired for more than 20 years, works late into the night almost every day。If someone asked him why he did it, "I get great joy from watching my students succeed?。"Is his answer。

　　As an older generation of Beili workers, Zhang Zhonglian pays special attention to the ideological education of students in the process of guiding students' innovative practice, and integrates ideological and political thinking into teaching, extracurricular scientific and technological activities and the cultural construction of the base。He carefully guided the students to design and produce mechanical innovation work "Long March Suite" with full marks, won the fifth National College students Mechanical Innovation Design Competition first prize。

　　In order to make a good teaching plan and teach students according to their aptitude, when each class of students enters the base, Zhang Zhonglian requires everyone to write a 400-word self-introduction and personally read it to understand the situation of each student。"I don't have to worry about my body, students send me home every day。They would take me to the door and then leave, has been so for more than ten years, especially in the weather of rain and snow, the students are dedicated to accompany。Chang Zhonglian lives on campus, and on his way home, there are always students who discuss problems with him。As Zhang Zhonglian gets older and older, the students accompany the "photoelectric grandpa" all the way。

　　"The peach and the plum do not say a word, a bush", "good teacher" Zhang Zhonglian has won the respect and love of generations of students in Beitech, in the Beitech "I love my teacher" selection voted by all students, Zhang Zhonglian was elected many times with high votes。

　　"I have nothing to advertise。In the face of the interview, Zhang Zhonglian said this sentence from time to time, but when it comes to students, he is as happy as a few family Jane, and his kind smile is full of happiness。"My students are better than me, they are young, smart, accept new things quickly, I can not use computer language, they taught me.。They are like the players in the race, they run very fast, and my role is only to hand them water and towels when they need it, and to be their attendant。”

　　Now, Zhang Zhonglian is pleased that the two young teachers of the innovation base, Zhang Lijun and Wang Dongxiao, are also like him, working tirelessly and selflessness in the teaching line every day。"We are a team, when I am too old to walk, and they will carry forward the spirit of the base, the spirit of the North Institute of Technology, I am relieved.。”
