At Seoul National Univ.

I have my B.S. degree in Mathematics Education. My undergrad major curriculum consisted of standard college-level math courses (such as sequences of courses in abstract algebra, real/multivariable/complex analysis, differential geometry, and topology) as well as specialized math-education courses (such as theory of math education,  educational technology in math education, teaching practicum). By following the curriculum, I had fulfilled all the requirements of the Teacher Certification Regulations under the Elementary and Secondary Education Act, and thus received the Secondary School Teacher Certificate (Grade II) of Math upon graduation. During my junior year, I started considering applying to math graduate schools, though I also loved math education courses. I made the firm decision to do so around the beginning of my senior year.
