Romantic poetry in Korea in the 1920s has not been regarded significantly in teaching literature, because the poetry is inferior to other poetries in the viewpoint of literariness. However, we should not forget the importance of the period of early 1920s, in that lots of development in Korean Literature was made during the period. That is because the activities of those poets in the 1920s shows us what the literary imagination is as well as establishes the concept of modern poetry and poet. Therefore, we can find the significance of them in teaching literature. This paper tried to find out a possibility of imagination education from the activities of romantic poets. It is generally accepted that in the history of England-America literatures the Romaticism is closely realted to the work of imagination. Their pursuit of unreal world must be one of the driving forces that enables the fertilization of their imagination. This trend is also found in Korean poets. The propensity of the Korean romantic poems can be summarized as follows. They admired artificial world that is based on denial of the reality, which did not pursue a healthy ideality but addicted to self-pathos. The passionate indulgence in their emotion must have been developed into sentimentalism, which created `red` or `violet` artificial space that is difficult to be found in previous Korean poetic history. The importance of their literary activity for literature education is as follows. First, it supplies a important hint to understand the meaning of literary imagination. The literary imagination is intensively associated in the creation of image which is deviated from logical relationship in the reality, which can be realized easily in poem rather than in narrative. It is also important to note that the sentimentalism of teenagers can become a important literary resource. Their vague dissatisfaction with the reality and desire to escape from it have lots of similarity to those of romanticists, which can serve as one of the important motives to enable the fertilization of their imagination. Their poem writing enables us to recognize what literary imagination is and can inspire students to write poetry and to create literary world. One can see that the imagination is utilized in every field. However, it does not work in the same manner. Literary imagination helps us go beyond the real world where reason dominates and experience the world transformed in a creative way through language.
