한국어 학습자의 구어 산출에 나타난 통사 복잡성 발달

Syntactic complexity development in spoken language produced by learners of Korean

The purpose of this study is to explain the development of syntactic complexity in Korean learners’ speaking. For this study, speaking tasks were carried out against 55 Korean learners(American, French, Chinese, Japanese) and the result was compared with 10 Korean native speakers. The research problem was to figure out how the syntactic complexity developed in spoken production, and the correlation between syntactic complexity and proficiency. The analysis of length complexity showed as the level of proficiency got higher, speaker produced the more clause in one AS-unit. In complexity related to sentence extension, the number of subordinate clauses per clause(AS-unit) and coordination index showed a significant linear relation with proficiency. This study found out that the syntactic complexity clearly developed between beginning level and intermediate level, and especially the number of embedded clauses in an AS-unit was an important index of syntactic complexity.
