Korean Language Learning Program
DS Sejong Hangeul (Sejong Korean) is an ICT-based Edutech program designed to help learners logically understand the structure and principles of the Korean alphabet, Hangeul, while mastering reading and pronunciation through sound-centered learning. Rooted in the phonetic philosophy of Hunminjeongeum, the program allows users to recognize consonants and vowels based on the shape and function of the speech organs used to produce each sound.
Learners can intuitively grasp how Hangeul letters are formed and separated by understanding its Building and Segment principles. The program makes the learning process engaging by incorporating chants, songs, hand activities, videos, and game-based content. Through this multisensory approach, which stimulates visual, auditory, and kinesthetic senses, beginners can naturally absorb the sound system and structure of Hangeul without losing interest.
Beyond basic character education, this program provides a deeper experience of the philosophy and creation principles behind Hangeul. Learners develop pronunciation, writing, reading, and comprehension skills in a balanced and enjoyable manner. It enhances self-directed learning abilities and language sensitivity, while improving retention efficiency to help learners achieve complete mastery of Hangeul.

Especially for foreign learners preparing to study, live, or work in Korea, the program offers an enjoyable and effective method to acquire Korean literacy from the fundamentals upward. DS Sejong Hangeul includes a full set of 30 printed textbooks along with multimedia content such as interactive e-books, providing a comprehensive learning experience that bridges traditional and digital education.
