About the Teacher
Auto-translated to English.
I have been working in the education industry for over 10 years. I have consistently accumulated teaching expertise by teaching students of various grades and levels. Through teaching in person, I have developed the experience and intuition to quickly identify the specific areas where students struggle. Online, I have felt a sense of accomplishment and pride in helping many students by delivering high-quality lectures to students nationwide through platforms such as KB Raschool and Mildang PT Math. Now, I hope to exert a positive influence on students across the country through the excellent platform called Kookoo. #10YearsInstructor #ESFJMathTeacher #MathPhobiaReliefPitcher #HighlyRelatableMath #WarmCharisma #CommunicationKingTeacher #ClassesNeverBore #HighTensionMathTime #YourPacemaker

중2-1 개념 완성! 기초 of 기초 !
When my child entered middle school, they attended a math academy for the first time at the beginning of the semester for about a month. Although my child silently and diligently completed the excessive homework, they eventually spoke up first, saying they wanted to study on their own using online lectures instead of going to the academy. Realizing that even a good academy requires a good match between the child and the teacher, we canceled the class after just a month. However, since online lectures are also not interactive, I was hesitant until I discovered the gem of a class taught by Teacher Lee Ji-woong on Kookgeu. I asked him to open the class, and as we took it, he really solidified the basic concepts. He also called my child by name and was generous with praise. If my child followed along well, he had them solve problems at a higher level. By setting a timer and solving them, my child’s tension, concentration, and problem-solving speed have naturally improved as a bonus. Although other children their age are already progressing incredibly far ahead, if you want to build a solid foundation and truly understand the material—like in the story of the Piggy Heart Brothers—I highly recommend this class.

1:1 맞춤 수업 : 부족한 구멍만 쏙쏙! 중등 수학 약점 보강 클래스
When my child entered middle school, they struggled with math and didn't attend any academies, so I was worried that there would be many gaps in their understanding starting from the basics. I couldn't properly finish the first semester and was concerned about how they would handle the first exam while working on geometry in the second semester, but fortunately, the results were good. Seeing their grades turn out well, they must have realized that they could succeed if they tried, so they said they wanted to take Kookeu classes. I thought about it a lot and looked into classes from various teachers, but I decided to sign them up because I thought one-on-one lessons would help them get the hang of it. My child is extremely satisfied. They said it was a whole new world they had never experienced with their school math teacher. They were fascinated and happy to finally understand the concepts they had been frustrated with before class. I hope they continue to receive good lessons to prepare for the second semester finals and even get ready for 2nd grade.

[겨울방학 부트캠프] 중2-1 개념 완성! 기초 of 기초 !
It was the first class, but my child said they understood it well because the concepts were explained in an easy-to-understand way. My child mentioned that they participated in the class in a better mood because the teacher was handsome, kind, and gave lots of praise.^^ Since advanced practice problems were also provided, we were able to study effectively for 120 minutes, covering everything from basic concepts to advanced topics. We are looking forward to the upcoming 2-1 classes and the 2-2 Basic Concepts Mastery class. Thank you. 😊
