A Study on the Comparative Analysis of Korean-Russian Language Ability of School-aged Koryoin Children in Korea

This study aimed at measuring Korean and Russian ability of Koryoin-school-aged(10-12) bilingual children based on lexical meaning (superordinate comprehension, hypernym expression) and grammar (grammatical error judgement, error correction) and comparing their scores with those of Korean or Russian monolingual children. As results, overall test scores surpass in Russian which is their home language, in particular in lexical meaning, but Korean test scores a little surpass in grammar. However, the scores are significantly lower than those of monolingual children, which shows that both L1 attrition and weak L2 acquisition took place in Koryoin children in Korea. The correlation analysis between Russian and Korean ability revealed negative correlations between Korean hypernym expression and Russian superordinate comprehension, and between Korean grammar error correction and Russian superordinate comprehension. The study found that length of residence and age did not always correlate with L1 attrition and L2 development, and other factors were intervened besides them.
