An Chang Hyon, a teacher of Sohae Senior Middle School in Waudo District, Nampho, could become a teacher of an inner-city school just after graduating from a university 15 years ago, but he opted to go to the rural school in his home village.
He devoted his selfless efforts and passion to improving the educational level of the school and acquired the qualifications to teach not only physics, his major, but also natural science, mathematics and English of junior middle school.
He developed several new teaching methods which help students easily understand what they learn in lessons in combination with actual life. He made dozens of kinds of teaching aids and experimental apparatuses so that all the experiments incorporated in the physics course of senior middle school could be conducted, thus greatly contributing to turning the school into a model one in rural areas, which can carry out all demonstration experiments and experiments on what students learn in lessons.
He wrote reference books necessary for the improvement of teachers’ qualifications and students' scholarly performance and made public several study papers in a foreign magazine through assiduous scientific research.
He was awarded the medal of honour for teachers for the distinguished service he rendered to train many reserve talents while taking parental care of students.
