Jeon Hyeongil (M) majored in Physics Education at Chonbuk National University and Teenage Education at the graduate school of the same university. Jeon wanted to be a teacher since childhood and decided to study physics because it seemed the easiest. But only after failing in passing many classes, Jeon realized the pain that many face due to the high barriers of science. He tried to teach science in a fun way, using authentic materials from daily life. He used to teach science at Sunchang Jeil High School and Jeonju High School. At present, Jeon teaches at Central Christianity Middle School and also does career counseling.
