How did your high school experience influence your decision to major in mathematics?

In this blog post, I will focus on my academic experiences and extracurricular activities during high school, examples of my consideration and cooperation with others, and my career preparation process.

 

Academic Experiences and Reflections

Even though I attended a general high school, I had the opportunity to take a special math class. A program was launched for science track students, modeled after foreign language high schools, where classes were conducted in English. I chose the math course and was required to participate for one semester. The program had a rule that accumulated penalty points for dropping out or frequent tardiness, which could result in being barred from continuing the course, so I had to approach it with a sense of responsibility from the very beginning.
The classes were conducted by guest instructors who lectured on math topics in English. At first, I could hardly understand the lectures, which was very frustrating, so I relied on solving problems by looking at numbers and diagrams rather than listening to the English explanations. Fortunately, since the material covered concepts I was already familiar with from my textbook, my ability to solve problems wasn’t significantly hindered even if I didn’t fully understand the English. However, I realized that to truly benefit from the program, I needed to improve my listening skills.
Around the third class, I tried a new strategy. Instead of focusing solely on the English textbook, I began attending class with my existing Korean textbook open beside me. First, I summarized the key concepts in Korean, and then, as I listened to the English explanation, words that I hadn’t been able to catch before began to stand out one by one, and their meanings started to connect naturally.
I wrote down the words I heard and understood in a separate vocabulary notebook, repeatedly reviewing their spellings and meanings. As my vocabulary grew, I was able to follow the flow of the teacher’s speech by connecting the words together. I also learned sentence structure through context and intonation, and later, I combined listening practice with taking dictation of the lesson content. By the end of the semester, I had achieved the goal of being able to understand more than half of the class content.

 

Major School Activities and Reflections

While in high school, I was active in “Jihwibong,” a math education volunteer club dedicated to serving the local community. Jihwibong was a small, student-run organization composed of students interested in educational volunteering; we primarily served by visiting nearby middle schools to provide one-on-one mentoring. Club members were divided among two middle schools, with each member taking responsibility for one middle school student, meeting regularly to provide both academic instruction and counseling.
A distinctive feature of our club was that we operated through individual mentoring rather than group classes. Each volunteer was assigned to one student, providing lessons tailored to that student’s individual needs, much like private tutoring. We built trust by listening not only to their academic concerns but also to the worries they faced in school life. By going beyond mere academic guidance to offer emotional support through conversation, we were able to maintain a comfortable relationship between the mentee and the volunteer.
The mentee I was assigned to was a second-year middle school student who was struggling with various issues, including peer relationships, family problems, and academic performance. Rather than jumping straight into lessons, our club ran a program called “The Bond Between You and Me” to give us time to get to know each other. This helped the student open up quickly, and we only began academic instruction after we had come to understand their personality and needs. This process was very helpful in reducing the time spent on icebreakers and increasing the efficiency of our lessons.
We began by administering a diagnostic test to assess the student’s current level and then focused on strengthening the subjects where they were struggling. Our club created our own comprehensive textbooks covering all subjects for middle school students, which we developed together as a team to ensure we never ran out of materials during lessons. I was specifically in charge of math tutoring, where I helped students by explaining various problem-solving methods concisely and actively answering their questions. After the tutoring program ended, I maintained close relationships with my mentees by participating in group volunteer activities with them, such as delivering coal briquettes, and these experiences left me with a deep sense of fulfillment.

 

Writing About Examples of Consideration, Sharing, and Cooperation, and My Reflections

Our school held a monthly school-wide cleanup, and each class was assigned a specific area. My class was responsible for the common restrooms located in the hallway, and I happened to be assigned to clean the restrooms due to the random number assignment. Many students were dissatisfied with having to clean the restrooms; in particular, because restroom cleaning was often assigned on a fixed basis—unlike other areas—there was a great deal of discontent.
To address these complaints, instead of just complaining myself, I encouraged my classmates to work together and systematically divided the tasks. We broke the work down into specific roles—such as mopping the floor, emptying the trash cans in each stall, and scrubbing the partitions and toilets with a brush—and each person took responsibility for their part. Although I wasn’t the cleaning leader, I led my classmates with a positive and proactive attitude and set the tone by emphasizing our shared goal of making the space we use cleaner.
My classmates carried out their assigned tasks with great dedication: they emptied the trash cans, lined them with fresh plastic bags, and cleaned every nook and cranny with brushes and mops. They also used antibacterial products and sprays to eliminate odors and scrubbed away stubborn stains with water. This diligent effort garnered positive reactions from my classmates and teachers alike, and by the end of the semester, it led to our class receiving an award for excellence in cleanliness.

 

Efforts and Preparation Related to Motivation for Application and Career Plans

Looking back on my three years of high school, my math grades were the strongest. My school grades consistently ranked among the top, and I was able to solve basic mock exam and College Scholastic Ability Test (CSAT)-style problems without significant difficulty. These achievements naturally led me to set my sights on a career in mathematics and higher education. Of course, high-level Olympiad-style problems remained a challenge, but my confidence in my strong grasp of the fundamentals served as a crucial foundation for my career choice.
The decisive factor that led me to dream of becoming a professor in college was the sense of fulfillment I gained through educational volunteer work during high school. While teaching middle school students one-on-one, I saw how grateful they were, and through the process of preparing lessons and developing teaching materials, I experienced not only the satisfaction of teaching itself but also the sense of accomplishment that comes from research. The profession of a professor, which combines teaching and research, aligns well with the direction I wish to pursue.
My specific plan is to enter college, build a solid foundation during my undergraduate studies, major in mathematical statistics, and prepare for graduate school. I plan to diligently take foundational courses in mathematical statistics as an undergraduate and gain relevant research experience, so that during my master’s program, I can pursue in-depth study by combining mathematical statistics with mathematics education. Subsequently, in the doctoral program, my goal is to grow into a researcher who can contribute to academia by conducting specialized research in mathematical statistics and carrying out research projects.
After admission, I plan to steadily expand my experience through teaching assistant positions, participation in undergraduate research, and educational volunteer work to simultaneously develop my teaching and research capabilities. Furthermore, I intend to prepare step by step for my graduate studies and future academic career by thoroughly reading papers and academic materials from my undergraduate years onward and by developing practical skills through research with my advisor. I hope to achieve these goals in the Department of Mathematics at Soongsil University and grow as a researcher and educator in the field of mathematical statistics.
