I am working as a high school teacher in Korea. The major award is the Hongjo Geunjeong Medal, the highest medal that can be received among Korean government officials, and the 2020 Global Teacher Prize Top 10 Finalist. I worked at a rural school for 30 years out of 31 years of teaching.

I unusually educated the students. If there was no way, I tried to find a way and teach the students. Let me introduce my teaching method.

The school I work at is in the commercial department. At 5 p.m., the commerce department teachers leave work. The commercial department teaches commercial students after school. I can't ask the commerce teachers to teach the automobile students computers after school. Only the automotive department can solve it on its own.

I am computer illiterate. I am not good at computers. Every time I write a document, I ask young teachers. Although I don't know computers, I will explain how my students got the most computer certificates in South Korea.

The high school I work in is a school where students learn skills. Learning the skills comes first. The regular curriculum is almost all about learning skills. Of course, there are computer subjects, but there is little time to learn. In today's society, you have to be good with computers. So, I taught the students essential Word, Excel, and PowerPoint after school.

I can't explain to students how to write computer documents because I don't know computers. So after school, I gather students into a computer lab. I asked the students what they were good at. Some students make diagrams well. And some students are good at Word. Some students are good at PowerPoint. I have completed how to do Word and Powerpoint Excel by collecting the parts that students are good at.

Each student has something they are good at. Students who are good at computers explain to students who do not know well. In this way, the lead student completely completes Word, PowerPoint, and Excel. Then the leading student guided the other student in pyramid form. I'm a teacher, but I can't explain it to students because I don't know them well. The student explained to the students. As a teacher, I only needed to manage students well.

Photoshop led unusually.

There were no students who knew Photoshop. Students must learn and have to practice to get a Photoshop certificate. The school where I work has a commercial department. In the commercial department, commercial students learn Photoshop. There was a female student who obtained a Photoshop certificate. The girl was friends with a boy from the automobile department. So I asked the female student to teach Photoshop to the male student in the automobile department.

Because she is a student, she doesn't know how to teach students. I helped the way to teaching students next to the female student. Boys learned how to use Photoshop. In this way, 40 automobile students obtained Photoshop certificates over three years. If there was no way, I didn't give up and found a way myself.

By educating students in this way, they obtained the highest number of computer certificates among all high schools in South Korea.

Next, I will introduce how I taught cars and construction machines.

To solve the shortage of practical equipment and the difficulty of educating many students at the same time, I came up with two ways as follows. Firstly, after the regular classes, the school classroom and practice room were open until 10 p.m. every night, so that students who needed living could come to school to practice and study skills after their part-time jobs were over. Secondly, I solved the shortage of equipment and the concentration on student education by rotating the club program that students wanted to learn in order.

As many students participated in club programs and they want various club activities according to their aptitude, it is impossible to teach every student at the same time. Thus, I only taught students how to study and let them study theory and practice on their own. I have developed their ability to learn on their own by conducting various project classes. Also, through various club programs, students were able to find their favorite field and choose a career path they want.

I selected excellent and quick-learning students as the leading students and directed them first. When the leading students finished their studies, they passed on their skills and learning to other students in the form of a pyramid and divided them into small groups by technology and certificate.

I created a job club, a gifted functional club, and a variety of license clubs such as automobile maintenance, agricultural machine maintenance, forklift, excavator, roller, bulldozer, crane, motor grader, document practitioner, MS Word, Powerpoint, Excel, Access, Photoshop, MOS, ICDL, 3D Scanner, CAD. I managed after-school activities every night until 10 p.m. (teaching 14 hours a day at school) even on Saturdays, summer, and winter vacations to help students master their skills.

As a result, students were encouraged to get many certificates (students received from 4 to 17 certificates per person) and have a wider career choice to have a job which is suitable for their aptitude as follows: an average of 11.5 certificates per person in 2009, an average of 17.3 certificates per person in 2012, an average of 12 certificates per person in 2017, an average of 7.9 certificates per person in 2018, an average of 7.7 certificates per person in 2019.

Students need to develop the ability to do things on their own in school education. In other words, schools teach students how to fish. It's not a place to fish and give it to students. You shouldn't educate students by fishing.

Teachers should discover and develop students' abilities. The same goes for companies. It is necessary to create an environment in which employees can maximize their abilities. This is because the development of company employees is directly linked to the development of the company.

It is impossible for a teacher to know everything and educate students. If a teacher does not know, he or she should find a way and teach students. If there is no way, you have to find a way. If I didn't find a way because I didn't know how to use a computer, maybe my students would have graduated without knowing how to use it. I tried and thought more than others to find a way myself. And I overcame difficulties. I found that way and continued to pursue it without giving up.
