This study aims to propose semantic educational contents considering the dynamics of meaning. The Korean semantic education has been implemented from the perspective of the structural semantics that meaning is fixed and a core concept exists in it due to the viewpoint that teachers should teach stable contents based on the traditional knowledge at school. However, meaning tends to be dynamic in a daily life. The meanings of the language are not determined or fixed only by the language itself and represents variously depending on contexts and situations. The use of meaning considering the user and the context including language, society, culture encompasses the educational value in that this can make the ability and creativity of language educated in the school. The study investigated the dynamics of meaning, and analyzed various meanings applied to a real life with Leech's types of meaning (1974). As a result, I suggested the semantic educational contents composed of those; the essence of the meaning through context, the value of assessment and implications for the objects, the types and in-depth understandings of the meanings, the interpretation and expression of the speaker's meaning, new words' meaning recognition and configuration.
