Hard core! The math teacher in charge of a middle school in Suzhou wrote 47 comments on "the sense of maximum number"

The final comment is not only a gift, but also an opportunity for education. Suzhou Lida Middle School has issued a "hard core" class teacher this year after a teacher introduced the "personality final comment" one after another, and wrote the "most quantitative" personality comment for 47 students in the class, which became a warm New Year gift for children.

"Y=2 to the X power, the process of accumulating knowledge is like an exponential function. At first, the value of y increases slowly, and then it grows faster and faster. The same is true of learning. Your development can be as well accumulated as an exponential function." "A circle is made up of countless points, each of which represents every step you have taken to study and every drop of sweat you have paid." "Gauss said that one half of the proof is equal to zero. It means that if you can't prove half way, you will not prove, and so will doing things." 47 comments are divided into multiple categories, including formula, theorem, definition, graph, etc, Formulas and geometric figures are drawn by Mr. Xu himself every stroke, expressing the beauty of mathematics while also conveying philosophy and the teacher's hope. Such comments suddenly "captured" the students' hearts.

Zhang Yixin, a junior student of Suzhou Lida Middle School, said she was very moved and surprised. "These function images let me feel the deep love of the math teacher for me. This is an inverse proportional function, this is a primary function, and there are two that have not yet been learned, which together means' love '."

Hua Rujing got a comment on the exponential function, "It began to grow slowly, and then it will become faster and faster, just like the accumulation of learning and the formation of habits. It is difficult at the beginning, and it will become more and more smooth when I get on track. I am encouraged to try to do some difficult things, and use persistence to get the final results.". I think it suits me very well, and I am grateful for my efforts in the past. "

Xu Jing, the head teacher of Class 11, Grade 3 of Suzhou Lida Middle School, wrote these "number sense" comments. She told the reporter that the idea of using mathematical formulas, theorems, and definitions to write comments had long been around. The students she brought into Grade 3 really started writing. She wanted to sort out the mathematical knowledge of the three years of junior high school and give it to students in a special way. This romantic challenge took more than three months to read six math books. It is not easy to combine the mathematical formula, student personality and teacher's message. Therefore, most of Mr. Xu's spare time is spent thinking carefully.

"Sometimes when it comes to mathematics, they will feel boring. I think mathematics is actually a romantic subject, which can even convey love. I want to encourage them, because students really care about the teacher's evaluation. As a class teacher, we need to do a good job in the evaluation every semester, which is also an opportunity to establish deep feelings with students. " Xu Jing, head teacher of Class 11, Grade 3 of Suzhou Lida Middle School, said.
