The story behind "Class is greater than Heaven";

"The class is bigger than the sky" is the teaching attitude handed down from generation to generation by teachers in the middle school attached to Jiaotong University. This slogan was put forward by Mr. Wu. Referring to the origin of this slogan, Teacher Wu said, "I didn't put forward this slogan out of thin air. The attitude of our school teachers towards the classroom, students and colleagues infected me. "

Teacher Wu once mentioned in an unusual math class that an 84-year-old teacher gave a new math class to a group of students in their 60s. There is no blackboard, he uses cardboard instead. In class, Teacher Chen Jie said, "Maybe these are useless to you, but I hope you can master them and pass them on to your grandson.

What kind of spirit makes teachers never miss classes in the teaching process? What kind of spirit makes an 84-year-old teacher pass on the essence of mathematics learning summed up in his life to more people! According to teacher Wu, "this really integrates education into the bones."

When I asked "What impressed me most during my teaching", Mr. Wu said: "My husband had cancer in his fifties. During the four years of fighting cancer, he was under the pressure of work and economy, and it was inevitable that he was absent from class. Usually, other teachers substitute classes, but in the end, he gave me all the substitute fees. " Speaking of this, Mr. Wu's voice choked: "Aside from the feelings among colleagues, in the middle school attached to Jiaotong University, all the teachers are thinking in one place and working hard in one place for fear of missing a class."

It is in this environment that Teacher Wu said at the experience sharing meeting when she was about to retire: "The teacher's duty is to teach. First, we must ensure that we are not absent from class, and second, we must ensure the quality. The second is management ... "Under the background that the leaders and teachers of the High School Attached to Jiaotong University attach great importance to the classroom and teaching, she put forward the slogan" The classroom is bigger than the sky ".
