시선추적과 뇌파를 활용한 한국어 학습자의 읽기 과정 분석

Abstract

Objective:The purpose of this study is to establish the goal with the reading stage of Korean learners in Korean language education institutions for preparing enter university using EEG and eye tracker. Background: International students enter the university after completing Korean language education finding lots of difficulties in classes handled in Korean. This is due to the current qualitative evaluation method adopted by the Korean teachers. Therefore, the international students need a proper learning method. Method: The Korean language proficiency test and learner’s level are classified as a beginner, intermediate, and advanced levels. The reading process was measured using Eye tracker and EEG. The independent variables consisted of 3 text level and 3 learner's level. The dependent variables consisted of fixation time, fixation number, saccade number, saccade time, and stress index. The variance analysis was performed with 3 × 3 within subject design. Results: As the text level increased, the fixation time and number were lowered for beginner, intermediate, and advanced learner. Even the number of fixation decreased, the understanding score as significantly increased. It was also found that the part of fixation number was related to process vocabulary and grammar. The text level significantly increased when saccade number increased. In addition, the saccade number significantly increased for the learner language level. There was no significant difference in the level of text difficulties between beginner and intermediate learners. Nevertheless, we found that advanced learners were confirmed with higher saccade time in beginner difficulty text. Conclusion: The fixation ratio was higher for beginner learners. Similarly, it was found that fixation time had a constant pattern with respect to learners' proficiency regardless of difficulty level. The saccade time affects the learners' level of text understanding. Also, the number of saccades associated with grammar and vocabulary. Application: In the future, if this study focus on a word and grammar in a sentence using EEG and eye tracking, this can prepare a study design for Korean reading system.
