"Teacher, what's the use of learning mathematics? The students are biting their pens, staring blankly at the blackboard and sighing at the complicated mathematical formulas. Such pictures often appear in math classes in different schools, and with the progress of further studies, the difficulty of mathematics only increases, so students lose their enthusiasm for learning mathematics.
However, in the class closed by the math teacher in Ruifang Senior High School, students can always find the fun of math.
The students of architecture department took a tape measure to measure the size of the wicker window in the famous historical site "Tianshan Tour" in Dihua Street, and explained the design concept and function of the wicker window. This is not an art class, nor is it architecture. This is a closed math class. He used the data measured by students to prove it with mathematical formulas, and took students to learn geometric formulas and understand the beauty of historical sites. Through interdisciplinary combination, Guan opened an artistic math class.
"Students will ask me to teach history, architecture or mathematics? I said both. Guan smiled and said to him. He is interested in architecture and likes to study Feng Shui culture. He is an atypical math teacher. Sometimes when students are bored in class, they will share the hidden principle of Feng Shui with them. " The student's eyes will light up because he has never heard of it. The curious eyes of the students made Guan begin to think about bringing architecture into the mathematics classroom, so that vocational school students can flexibly use undergraduate textbooks when studying their own professional subjects.
Guan began to take students to "outdoor teaching". He asked students majoring in civil engineering to measure the diameter of the Hakka enclosure in Miaoli with measuring instruments, and then calculated it with the equation of circle, which proved that the Hakka enclosure was "round". They also appeared in front of the moon cave in Banqiaolin Garden. After measuring the data, the students tried to prove that the door was round. Guan continued to ask the students, "If three points on the plane are not collinear, how many different circles can be formed?" He used different topics to make students think and make mathematics more active.

In addition to mathematics, architecture and measurement, Guan also takes advantage of outdoor teaching opportunities to give students art classes and history classes. He loves China culture and expects students majoring in architecture and civil engineering to integrate the traditional aesthetics of China culture when designing buildings in the future. Visit the ancient buildings of Lin Antai and enjoy Taipei 10 1. He explained to the students how to use geometric figures in the building, and also shared the design concept behind the building with the students. "I hope they can integrate into China culture when designing buildings in the future, and don't just say that they look good. Good-looking is very abstract, and we should be able to explain clearly the image represented by architecture. 」
Besides outdoor teaching, Guan also lets students "practice" math. Boxes of colored building blocks are piled up under the desk. On the messy desktop are math handouts and antique models of Lin Antai made by Lego. The lockers on the side are filled with architectural models of different colors and proportions. Students are required to use building blocks to design buildings with geometric figures, share design ideas, and combine mathematics with art through practice.
He also used the computer GeoGebra software to teach students to draw a totem with baroque architectural characteristics by using mathematical equations, thus combining mathematics with aesthetics and cultivating students' mathematical ability and creativity.

108 future courses emphasize interdisciplinary teaching and cultivate the ability and attitude to face future challenges. Therefore, it is necessary to combine courses in different fields to cultivate students' practical ability, hoping to maintain students' learning enthusiasm and motivation. "I hope he can determine his major and like it when he goes back to study mathematics. That's enough. 」

From outdoor teaching to practice, the courses of management are rich and colorful. Hong, an architecture student, said, "I never thought I could combine these two majors, so I just tried to learn one more lesson for myself. Although he has not made great progress in mathematics, Hong said with a smile that he has worked hard and has a clear conscience.
In the students' works, Guan pointed to a model of a Japanese shrine and introduced the students' original design concept. "Students can have ideas and make a difference because of my course. I think this is the most enjoyable thing for a teacher. Guan lamented that educational innovation requires great enthusiasm. " Often complain that students are not good enough and there is no way to change anything. I must think about how to change and innovate. 」
Previous teaching plans have been affirmed by many awards. He also went out of school, visited other high schools and shared his lesson plans, hoping to bring some changes to education. Next, Guan hopes to cooperate with teachers from different disciplines in the school. "When we can achieve A+B = C, we can create changes, and so can the curriculum. Combine mathematics with many fields and tell students in life: "Mathematics is very useful. 」
