A Study on Establishing and Validating the Korean Version of the Language Frequency Profile: Mainly through Analysis of Lexical Sophistication

The purpose of this study is to validate the Korean version of the Language Frequency Profile (KLFP) constructed using a vocabulary list. Through analysis of the KLFP in the writing of intermediate and advanced Korean learners, significant differences were found between the two groups. The same results were obtained when the intermediate and advanced groups were further subdivided. The findings indicate that learners with lower proficiency tended to use more frequent vocabulary (K1, K2), whereas those with higher proficiency tended to use more sophisticated vocabulary (KAWL, K3). However, when the learners' writing was controlled by topic, the intermediate and advanced groups could not be differentiated in detail, and the order of use of the frequency levels of the KLFP varied depending on the specific topic. Therefore, it was found that it is difficult to classify learners based solely on lexical sophistication. This study is the first in Korean language education to use a reference list to measure lexical sophistication, and it is meaningful in that it was able to identify how the pattern of vocabulary usage varies by KLFP depending on the learner's proficiency.
