Accordingly let Chinese learners translate two poems into Chinese and retranslate Korean. considering translated text by learners as a kind of self-regulated input modification. As a result, this research shows various aspects of text modification such as addition, repetition, substitution, replacement, transformation, reconstruction at lexicologic, morphologic, syntactic levels. From an educational point of view, learners’ translation of poetry can be used in relation to translation criticism class in which learners learn compare, contrast their own translation and others. This helps learners mutually experience linguistically, culturally. Above all, it will bring interaction between teacher and students, among students to language class. (Semyung University)
