학습용 전자책의 텍스트 길이와 정보탐색 유형이 시선고정 시간, 인지부하, 학습이해도에 미치는 영향 = The Effects of Line Length and Information Seeking in E-Book for Learning on Eye-fixation Time, Cognitive Load, and Comprehension

다국어 초록 (Multilingual Abstract)

The purpose of this study was to examine the effect of line length and information seeking strategy on eye-fixation time, cognitive load, and comprehension score. The participants of this study were twenty-six college students(female=19 and male=7). The independent variables were text line lengths (long=50 character per line vs. short=25 character per line) and types of information seeking strategies (scanning vs. skimming). The dependent variables were eye-fixation time, cognitive load factor, and comprehension scores. For the eye-fixation time, the eye tracking method was applied for this study. The participants were randomly assigned either long line or short line format of expository text. The participants were asked to perform two reading tasks: Scanning and Skimming. Scanning task was to find out specific concept or keyword, and skimming task was to summarize the passage. For the eye-fixation time there were significant differences between types of information seeking strategies. When the participants were asked to perform a skimming task, their eye-fixation time was significantly increased compared to scanning task conditions. Further, the participants` eye-fixation time showed significant interaction effect between types of information seeking strategies and line lengths. This result revealed that line length can be an important design factor when a learner is reading e-book for learning. There was a significant difference of cognitive load factors in skimming condition. The participants with short line length condition showed higher perception of usefulness. There was no significant difference by comprehension scores. The study made three suggestions for those who are designing e-books for studin.
