I feel shy introducing myself. I have always enjoyed writing, reading books, and talking about various things. Now, I am teaching children using those very things I love. I constantly ponder and ask myself: What kind of impact will this class I am conducting actually have? Do they truly understand it? I still don't know the answer, but I think I can say this with confidence: I believe I am teaching classes that I am satisfied with and enjoy. History, economics, philosophy, psychology, book discussions, writing, etc. I believe that studying is not merely about taking exams and getting good grades, but a 'process' of having fun and getting to know oneself. In particular, while preparing for classes, I also feel my own shortcomings and learn. Just as the theme of all young adult novels is 'growth,' I hope my classes reflect that as well. 📚 Teacher Jeongtan's Reading & Essay Roadmap 📚 - Pre-test [Level Test] Which Curriculum Is Right for You? - Non-fiction Roadmap 1.

[중등 수행평가까지 대비] 정탄의 ALL-IN-ONE 시즌 2: 클래식

My child is intuitive and has a strong inclination toward science. He was the type of child who would write the correct answer to problems requiring both the answer and the solution process, but then write down the reasoning in the solution step, saying, "Because this is the answer." He wrote the answer because it was obvious at a glance, so he would ask why a solution process was necessary, and instead demand that I convince him. He was the type of person who knew a lot but struggled to organize his thoughts. My child has spent a long time with Teacher Jeongtan. By unraveling the tightly tangled threads of his thoughts one by one, he has rearranged his capabilities. He is truly a teacher I wish I could keep all to myself. He is someone who brings out my child's strengths to the fullest.

정탄의 초등 로지컬(Logical) - 초등 비문학 독해(과학, 기술, 경제, 철학)

It was very difficult at first, but as time passed and I mastered the methods one by one with the teacher, I learned more and felt good as my knowledge grew. The teacher is also a righteous and realistic person. There were times when the homework was tough, but I am getting used to it. The teacher also has a surprisingly funny side. They are the teacher who made me painfully realize that studying might seem easy, but it actually isn't. There was a homework assignment to transcribe entire sentences, and at first, I thought, "How much could I really improve by transcribing?" But after actually doing the homework, I was surprised to find that the words were stuck in my head. (Review written by a 5th grader)

5-6학년을 위한 북토크와 생각 글쓰기 : 어린이 소설과 논술

Teacher Jeongtan's classes are always fun and informative, no matter when I take them. Unlike the rote memorization prevalent in our country's public education system, his classes focus on mutual discussion and empathy. They allow students to understand differences, gain deep insights, and learn about life—a type of class rarely found in Korea. Although the teacher is humorous, he delivers exactly what is needed in a blunt manner, making the lessons truly thought-provoking and meaningful. Regarding writing, the feedback he provides allows us to reconsider, revise, or add to our work, thereby improving the quality of our writing. I wish I could enroll in all of Teacher Jeongtan's classes, such as his non-fiction and all-in-one history lessons, but unfortunately, I don't have enough time!
