A Study on the Vocabulary Development and the Lexicon Use Aspect of Korean Learners: Focusing on the Lexicon Measurement Appearing in the Writing Text

The purpose of this study is to reveal the vocabulary development following the proficiency and the lexicon use aspect by quantitatively measuring the lexicon appearing in the Korean learners’ writing text. The number of lexicon realization and the number of lexicon type increased quantitatively following the proficiency in the writing text calculated by the Korean learners from the level 1 to level 6, and the statistically significant difference was shown in the average number of lexicon by proficiency. On the other hand, there was a difference by proficiency in the speed of the lexicon development. There was remarkable vocabulary development in the level 4 because the number of lexicon increased rapidly. In level 5, the number of lexicon rather decreased so the vocabulary development became stagnant. It was revealed that learners made use of various lexicons only when the level became 6 in terms of the lexical diversity(TTR).
