The purpose of this research is to identify differences in the reading process between intermediate and advanced Korean readers with eye-tracking technologies. First, during the reading process, seven foreign advanced and seven foreign intermediate Korean readers’ total fixation duration, fixation counts, and fixation duration averages were analyzed to observe the differences. Second, the divergence in saccade amplitude averages during reading process between two group of readers was measured. Third, differences in the scan path during reading were analyzed between the two group of readers. Lastly, think aloud interviews were performed after the experiment with the readers. The result of the experiment follows: total fixation duration was shorter for advanced readers by about 8,000-9,000㎳, number of fixations was higher for the intermediate readers by about 1.35 counts. Also, during the reading process, the scan paths indicated that the intermediate readers processed the reading material from the questions to the main text to the answers. On the other hand, the advanced readers processed the material from only reading the title and/or the small portion of the main text, then, to reading the answers to find right portion for deciding the correct responses.
