LexTALE-Korean의 개발과 타당성 검증: 효율적인 한국어 어휘 평가 도구

초록

This study aimed to develop the Korean-version LexTALE and examine its effectiveness in estimating Korean learners’ proficiency. 41 advanced and intermediate Korean learners participated in a web-based lexical decision task in which 120 Korean words and nonwords were tested. They also took part in a reading comprehension task and a cloze task. The results from a series of logistic mixed-effect models revealed that first, the LexTALE-Kr accuracy significantly differed between language groups in a way that Korean natives obtained higher scores than Korean learners, and advanced Korean learners gained higher scores than intermediate Korean learners. Second, the effect of lexical frequency on lexical decision accuracy was significant, and its effect was the biggest in advanced Korean learners. Third, the scores obtained from the reading and cloze tasks significantly accounted for the accuracy variances of Korean learners. Taken together, our results supported the claim that the simple and low-cost online test evaluating learners’ lexical knowledge is adequate to estimate the goodness of learners’ proficiency as much as complex and high-cost comprehensive examinations like TOPIK.
