 [Chongqing Institute of Engineering said] Shoubin Xu : "Craftsman" Stick and Lift

Net news (article/ Party Committee propaganda Department, college students press corps Yuting Fan picture/ College press corps Yuanhao Zhang) Teachers preach and teach to dispel doubts. On the campus of Chongqing Institute of Technology, there is such a group of teachers who do not forget their original intention and selfless dedication. They are knowledgeable and sincere, and are the "guide" of students' growth; They are the "navigator" who leads students to swim in the ocean of knowledge. They brave the academic "new heights" in the laboratory, and constantly climb the peak of science. They go around the business looking for connections, just to let students have a better internship platform... ‘Chongqing Institute of Engineering said’ the column focuses on teachers with outstanding achievements in teaching, scientific research, education and other aspects of the school, and through in-depth interviews, carries forward the teacher's ethics and style, further promotes the spirit of teaching and educating teachers and students of the whole school with the power of example, and creates a good atmosphere of overcoming difficulties and selfless dedication in the whole school.

"Our lab is open. Students who want to do experiments can come to the lab any time they want, as long as they make an appointment with the experimenter or teacher." After a phone call from the student, Professor Shoubin Xu, who was interviewed in the office, hurried downstairs. It turned out that Juan Liu, a student from Class 3 of Grade 21 civil engineering, doubted the yield load data of low carbon steel in the last experimental class and wanted the teacher to answer it. In the process of the experiment, Shoubin Xu selected mild steel specimens in response to students' questions, lowered the load value per unit time, increased the experiment period, reproduced the whole experiment process, and obtained the yield load data again. In addition, cast iron specimens were selected for tensile comparison experiments, and Juan Liu understood the differences in mechanical properties between plastic materials represented by low carbon steel and brittle materials represented by cast iron during axial tensile. This is a small interlude during the interview.

Long search - industry "big hand" steady rudder building foundation.

When asked, for the first national safety production emergency experts, Chongqing emergency management expert group experts, Professor Xu in spare time for students to guide such a basic experiment whether "kill chicken" with "ox knife"?

"If the foundation is not strong, the earth will shake." Shoubin  Xu replied.

Theoretical mechanics, material mechanics, structural mechanics and other basic mechanics courses are important core professional courses of civil engineering major in the School of Civil Engineering. To establish a clear and systematic mechanical knowledge system is the basis for students to learn the theory of civil engineering and carry out engineering practice.

And these three core courses are not so simple to learn, there are professional "experienced" said, "the most difficult subject of the student exam is the three major mechanics" "Whenever I feel that professional courses can not go on, think about not testing the three major mechanics, I feel that what is difficult to back a few books." There are many contents and formulas of the three major mechanics, the theoretical analysis needs to be supplemented by experiments and hypotheses, the concepts are many and difficult to understand, and the calculation is more complicated...

For Shoubin Xu, the national excellent teacher of mechanics teaching and the first prize winner of the first National basic Mechanics young teachers teaching competition, to do a good job of the "gatekeeper" of the three mechanics, he firmly believes: "to be worthy of the students, worthy of the parents who give the students to the school."

This is the way of Shoubin Xu .

"Practicing after class is the best way to consolidate what you've learned in class." So after each class, Shoubin Xu  will assign two or three typical examples to let students consolidate the knowledge of the class, "my class does not accept electronic files of homework." In today's electronic file operation is very common, Shoubin Xu 's adherence seems to be some "alternative".

"Unlike other subjects, mechanics assignments can be done electronically by lazy students who can copy and paste them, which is of no use to them. Paper files at least allow them to continue to familiarize themselves with formulas." Shoubin Xu  held the students' homework book, "At the beginning of many students' words flying, I will use the same handwritten way to correct their homework, see the teacher seriously, they will slowly write well, well done." "Like paper assignments, handwritten lesson plans allow me to sort out my thoughts and questions at work." Teaching more than words, Shoubin Xu  infected every student with his actions, avoiding impetuous, rigorous research.

"When talking about the calculation of bending normal stress strength, Professor Xu would ask us to look down at the welded triangle area under the desk and tell us that the bending moment here is the largest, which is the most prone to failure, so using welding to fix it can reduce the damage and make us better understand what we have learned." For Shoubin Xu 's strict requirements, Li Cheng of Class 4 of civil engineering, Grade 2020, was not used to it at the beginning, but later slowly understood the mystery of mechanics.

"As a teacher, attitude is more important than ability." This is a word that Shoubin Xu  often says to young teachers, and it is also the educational concept that he has always adhered to, and he has set an example for young teachers. After getting each textbook, Shoubin Xu  will do the exercises one by one, and organize them into a book, and then screen out the basic types of questions suitable for students, and help them consolidate knowledge points in the form of homework. "Understanding the content of the curriculum is the foundation and the only way to be a good teacher." To achieve integration is not simple, Shoubin Xu  lamented "one minute on the stage, ten years of work under the stage".

In the 13th National Zhoupeiyuan Mechanics Competition for College Students, students Shiyin Li and Jiangyun Ye, who were tutored by Shoubin Xu , competed with mechanics talents from various universities in Chongqing and won the second prize of Chongqing Competition. Shoubin Xu  also won the award of "Excellent Instructor of Chongqing Competition". A few months ago, Junlin Li, a student of Civil Engineering Class 4 in 2019, was successfully admitted to Chongqing Jiaotong University in the postgraduate examination, and his mechanics of materials achieved a high score of 121. In the message sent to Shoubin Xu , he sincerely thanked him: "Professor Xu's mechanics of materials course is fresh in my mind, and also gave me a lot of help, thank you 'Xu'."

Hold the line -- lift as hard as I can

"Professor Xu is also an expert in supervision in our school, and the first class for a new teacher in our department is Professor Xu's class." Speaking of Shoubin Xu , Lin Jun, head of the department of Civil Engineering at the School of Civil Engineering, said. The mechanics teaching team led by Shoubin Xu  has carried out a series of standardized curriculum construction from the aspects of outline revision, curriculum setting, process assessment, weekly practical training, and paper standardization, so that students can lay a solid foundation from the beginning of contact with the major. "Only by consolidating the foundation and building a solid foundation can we go further and further." This sentence Shoubin Xu  often hangs on the mouth.

The college combines the orientation of application-oriented personnel training and the specialty characteristics of "information technology +" to build a segmented and distributed professional training system. And "mechanics" is the key to open the door of "architectural engineering", which runs through the whole process of professional education. With such a foundation, students can achieve good results in both housing construction engineering and road and bridge engineering. In the past three years, the civil engineering students of the College of Civil Engineering have won more than 90 awards in all kinds of competitions, including more than 40 national awards, in 8 discipline skills competitions such as the National College Student Structural Design Information Technology Competition, Chongqing College Student Tunnel Design Competition and 3 innovation and entrepreneurship competitions.

"For decades, I have only repeated one thing, that is to lay a solid foundation for students, and every progress we have made is from the joint efforts of all teachers and students in the School of Architectural Engineering." The foundation is solid, the tall buildings are built, and the students can only see the higher scenery on the shoulders of the teachers." Seo Shoubin said.
