　　In the 4002 classroom, behind the students' hard study, there is indeed a "lamp" that shines on the soul and cares for growth. He is the 84-year-old professor Zhang Zhonglian, founder of the photoelectric Innovation Education Experimental Base of Beijing Institute of Technology。

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

　　A "news feature" with only 531 words, entitled "In Beijing Polytechnic, there is a light called" 4002 at 11:00 PM ", was published on the Beijing Institute of Technology News website, and was clicked more than 10,000 times in a short time。

　　On the campus of Beijing Institute of Technology, this scene is played out every day。In the 4002 classroom, behind the students' hard study, there is indeed a "lamp" that shines on the soul and cares for growth. He is the 84-year-old professor Zhang Zhonglian, founder of the photoelectric Innovation Education Experimental Base of Beijing Institute of Technology (hereinafter referred to as the base)。

　　"Deliver water and towels, do a good job"

　　A little bit to midnight 12 o 'clock, an octogenarian, a group of young students, out of the teaching building, accompanied by the road, still keep discussing the problems in the experiment。Zhang Zhonglian, who has been retired for more than 20 years, has to work late into the night almost every day, and it is early morning when he returns home。

　　"You don't have to worry about my health, students send me home every day.。This has been the case for more than ten years, especially when it comes to rain and snow, the students are dedicated to accompany them。Whenever people "worry" about his late return, he always explains, "I feel great joy to see the success of my students."。

　　In the photoelectric innovation education experimental base, Zhang Zhonglian likes to walk among the students of different colleges and majors to point out the maze and point out the direction。

　　When each class of students entered the base, Chang would ask everyone to write a 400-word self-introduction and personally read it to understand each student's situation。Before making a teaching plan each semester, he would talk with students, listen to their needs, and then formulate the teaching content of the base based on it。

　　Every semester, the class time of the base is repeatedly coordinated by him, so as to avoid the conflict of class schedules among students who choose courses。Sometimes students miss classes due to illness, and he will arrange base teachers to make up for them。When energy permits, he will personally mark each test paper, and put the excellent test papers into a book for the next class of students to watch and learn。

　　"My role is just to hand them water and towels when they need it and be their orderly.。"Zhang Zhonglian said modestly。

　　Give me a base,

　　Give you 10,000 excellent students

　　Recalling his college days, Chang described himself as a "shoulder-shouldering" student leader。He is the deputy head of the life department of the Students' Union, and clerical work inevitably eats into study time。"Thanks to the school having a study group system, with the help of the group, I never fell behind。”

　　After staying at the school, Zhang Zhonglian inherited the tradition of "learning extracurricular activity group". Inside and outside the classroom, he often organized students to research projects and problems in small groups, discuss with each other, review old knowledge, and cultivate students' sense of teamwork。

　　In 1985, Zhang Zhonglian opened the compulsory course "Experimental Technology of Instrumentation Electronics", and the training of students' practical and innovative ability in the course has been recognized by all over the world。Back then, Zhang Zhonglian regarded this course as the beginning of the "base" career。

　　After years of exploration after retirement, in 2000, the Beijing Institute of Technology granted 150,000 yuan of funding to support Zhang Zhonglian to establish a base, hoping to create a new model of cross-professional training students' practical innovation ability and improving students' scientific quality。

　　Under the leadership of Zhang Zhonglian, the base quickly became a gold medal project for innovative practice and education of the Beijing Institute of Technology。Here, a large number of students with outstanding innovation ability have emerged, and they have won gold and silver MEDALS in the "Challenge Cup" National College Students extracurricular academic science and technology works competition, the National College Students Mechanical Innovation Design Competition, and the National College Students Photoelectric Design Competition。More than 10,000 students have exercised here and gained growth。

　　"My students are my teachers"

　　Students who have done innovative practices under Chang's guidance always refer to themselves as "base" people。

　　"The base breaks the existing classroom teaching model, stimulates students' hobbies and interests, so that we can learn independently, and mobilize enthusiasm by participating in competitions, so that we can apply what we learn.。"Base" of people, 2008 graduate Wang Benxin said。

　　Passive learning is unlikely to produce innovative talents, and encouraging students to let go and create is one of the keys to the base's success, according to Chang。"In class, teachers should first explain knowledge systematically, then guide students to practice modules, and finally, students write a summary report to deepen memory learning;In extracurricular activities, students should first be allowed to practice and make a model similar to the expected purpose, and then teachers should intervene and give targeted guidance。”

　　Talking about the characteristics of the base, Zhang Zhonglian full of experience。"By guiding students' free exploration, establishing a new training model that integrates students' interests and innovation potential, and consciously mixing students from multiple colleges, different disciplines and different majors to form teams, training students' ability to cross disciplinary knowledge.。”

　　In groping，He also established a set of teaching models to guide students to innovate and practice - while establishing the best knowledge structure，Guide students to build the optimal intelligent structure gradually，Pass experimental electives in the early stage of undergraduate study，Lay a good foundation for practical ability;In the later stage, the two teaching links are graduation practice and graduation design，To achieve the purpose of comprehensive use of knowledge to solve practical problems。

　　"My students are my teachers。Ask students for advice on what and how to teach it。Zhang Zhonglian insisted on the concept of teachers and students and teaching and learning, he often said, "Innovative education does not need to debate, put your method out, let students go to the factory, the laboratory to test the most effective.。”

　　He used 19 years of cold and summer to integrate the "student-oriented" concept passed down from generation to generation into the training practice of innovative talents。Today, "4002 at 11 o 'clock in the night" is still clear, "4002 light" has become a synonym for the encouragement of the North Institute of Technology。

　　To Zhang Zhonglian's relief, Zhang Lijun and Wang Dongxiao, the two young teachers of the innovation base, are also like Zhang Zhonglian, dedicated to their work every day。"We were a team, when I was too old to walk, and they carried the spirit of the base forward。”
