Hello. I am Jang Yu-mi, a math instructor and the representative of ‘Oneuldamda Math,’ who has guided a diverse range of students, from elementary schoolers to middle and high schoolers and those retaking the college entrance exam. I began teaching as an academy instructor in 1997, served as an external lecturer for middle schools, and later as the director of a math academy. Since 2010, I have been operating ‘Oneuldamda Math.’ Meeting students in various educational settings—including academies, schools, and online classes—I have guided even those who find math vaguely difficult to easily grasp concepts and approach problems step-by-step. Through teaching children for a long time, I have realized that the reason they struggle with math is not simply due to a lack of calculation skills. Many students seem to understand the explanations during class, but when they try to solve problems on their own, they stop because they do not know where to start. This is because they cannot identify which of the various conditions given in the problem to examine first, or where to apply the concepts they have learned. When this experience is repeated, children come to think the problem is difficult before they even read it sufficiently, or they conclude that they are bad at math. Ultimately, students fail to properly utilize even what they already know and easily give up when the wording or conditions of a problem change even slightly. Therefore, in my classes, I begin by identifying what needs to be found in the problem. I organize the given conditions one by one, examine the relationships between them, and then explain step-by-step how to connect them to the concepts they have learned. I teach students so that they do not stop at simply following the solution exactly, but can find their own starting point even when encountering new problems. * Major Teaching Experience - 1997–2002: Instructor at Deungyongmun Academy - 2002–2004: Instructor at Wooinsung Academy - 2004: External Lecturer at Namgang Middle School - 2005–2010: Director of Haebop Math - 2010–Present: Representative of ‘Oneuldamda Math’ - 2024 & 2025: Lecturer at Baekma Middle School - 2025: Lecturer at Incheon Sewon High School - 2026: Lecturer at Bundang Aram High School * Zoom Classes Continued for Over 4 Years For approximately four years, I have been conducting Zoom classes for middle school, high school, and college entrance exam retakers who find it difficult to attend in-person classes due to distance. Currently, I continue to provide online instruction to 2nd-year middle school and 3rd-year high school students residing in other regions, as well as students living in Canada. I have also consistently conducted special Zoom lectures for students who find it difficult to participate in regular classes. I have honed my skills in observing student reactions and engaging participation online by conducting not only individual tutoring sessions but also numerous Zoom classes with multiple students. Leveraging my experience teaching large groups of students in one place at schools and my diverse Zoom teaching experience, I conduct classes online that allow multiple students to understand and participate together. My lessons begin with simple explanations and basic problems that children can follow without feeling overwhelmed. After verifying that students have properly understood the material, I gradually adjust the wording and difficulty of the questions to connect them to actual exam questions. I repeatedly address areas where students frequently make mistakes or find confusing, and I explain problems that look similar but require different solutions by comparing them. Even in online classes, I ensure students do not simply listen to the teacher's explanations; instead, I engage in Q&A sessions and solve verification problems together at regular intervals. I encourage students to share their solutions and thoughts, and immediately check how much they have understood. By reviewing their answers and problem-solving processes, I re-explain areas that are particularly confusing and connect them to the next problem to continue the lesson. I hope to reach more students through Teacher Koog, free from geographical and time constraints. Based on my long experience teaching students, I will teach in an easy and meticulous manner so that children do not view mathematics as unconditionally difficult, but instead gain the confidence to think, "I know how to solve this."
