한국어 학습자의 작문에 나타난 정확성과 복잡성의 역동성

Dynamics of Accuracy and Complexity in the Written Production of Korean Learners

The purpose of this study is to investigate the dynamic developmental process of inter-individual and intra-individual variabilities through accuracy rates and complexity measures of free written essays. This study tracked the written production of four Korean beginners over six months. With time, there was an overall increase in the development of the group’s average syntactic complexity and lexical diversity, but their accuracy decreased. However, there were differences in inter-individual and intra-individual variabilities over time. As a result of the comparison of inter-individual variabilities, it appeared that the developmental process of learners is non-linear and individual developmental paths are quite different from one anther. Also, within intra-individual variabilities, interaction existed between accuracy, syntactic complexity and lexical diversity. In particular, clauses per sentence and words per sentence appeared as connected growers, and according to the learners, these two measures appeared as competitors with words per clause and lexical diversity.
