Completed over 60 hours of educational volunteer work during university, teaching students who were economically disadvantaged or struggling academically. This experience provided exposure to a diverse range of students.
Conducted a teaching practicum at a middle school, where observation of mentor teacher’s classes in the first week enabled learning about class management and student guidance. For the next three weeks, led classes independently, culminating in a representative teaching demonstration and receiving valuable feedback from multiple teachers.
In 2016, served as a part-time instructor at Youngjin High School for one semester, teaching students with low academic performance. This role involved exploring various methods to foster students' interest in English.
From 2018 to 2019, worked as a TOEIC RC instructor at Pagoda Academy in Jongno and Sinchon. Teaching materials were consistently revised each month, every available TOEIC exam was taken, and supplementary materials focused on grammar and reading comprehension were developed. This effort resulted in a high-accuracy, concise supplementary book covering essential points. Positive feedback from the academy led to achieving the second-highest position within six months, surpassing teams with over ten years of experience, which led to an invitation to transfer to the Sinchon area.
Since July 2019, employed at Henry English in Banpo. Transitioned from teaching TOEIC to instructing middle and high school students to better align with teaching strengths. Joined the team during an expansion from the Gubanpo area to the Seocho area, and consistently received positive feedback from students and parents, including remarks such as "The classes are enjoyable and effective," and "One of the best English teachers." At Banpo High School, one student improved from a grade of 3 to a grade of 1, and over 30% of students at Wonchon Middle School achieved a perfect score of 100 in exams. This success resulted in becoming the instructor with the highest number of students at the academy.
Since 2021, employed at Hamyoungwon, a specialized entrance exam academy in Daechi-dong, teaching students across a wide range of ages and levels, from elementary to high school. With experience in instructing all levels, from beginner elementary students to top high school students, a high level of versatility in handling various classes has been developed. Over four years, an intensive teaching schedule—seven hours daily during the regular semester and eleven hours daily during vacation periods—enabled learning through trial and error, resulting in a proven method to help students quickly grasp concepts and apply them to problems. Middle school exam preparation classes are conducted in mixed-grade groups with students from various schools, providing the opportunity to teach curriculum and exam preparation for all textbooks used in grades 7 through 9 in the Daechi-dong and Gangnam areas. Accumulated a comprehensive set of teaching materials for all textbooks, enabling optimized exam preparation classes.
In 2023, recorded online lectures for elementary students with Woongjin Smart All, in collaboration with Hamyoungwon Academy. Despite the demanding schedule of working seven days a week, recording online lectures in the morning and teaching in-person classes in the afternoon, this experience offered fulfillment as an educator by providing high-quality lectures accessible to students nationwide. Reviewing recorded lectures facilitated significant improvements in small habits and speech patterns that might not have been noticed during in-person classes.
