| Summary: | 碩士 === 中山醫學大學 === 生物醫學科學學系碩士班 === 101 === The purpose of the study was to analyze and to establish the ocular movement model by using Readalyzer of elementary school students in Taiwan.
Among 622 grade 3rd to 6th elementary school students; there were only 75 (12.06% of total)qualified cases who passed most of the screening items. Researchers Used Readalyzer to record the eye movement, like fixations, regressions, fixation duration, and reading rate) when students were reading.
Results indicated that the age or grade-dependent increase, students’ fixations times decrease from grade 3rd to 6th at 112.64, 116.68,90.47, and 76.68, respectively. The number of regression/100 words also decreased from 3rd to 6th Grades at 28.79, 25.26, 20, and 15.32, respectively. So did the fixation duration changing from 3rd to 6th Grades at 0.4114, 0.3047, 0.2906, and 0.3060 sec, respectively. At the same time, the reading rate increased from 3rd to 6th Grades at 181.86, 223.84, 271.53, and 291.52, respectively. In addition, these reading eye movement parameters were significantly correlated with binocular horizontal movements, such as saccade (r=0.376~0.446, p=0.013~0.037), NPC break and recovery (r=0. 496~0. 648 , p=0.006~0.036). The data were also compared with English reading, and significant difference was noted in fixation (t=-2.761~ -7.265, p=0.000~0.016), regression (t= -2.962~ -4.988, p=0.000~ 0.009), fixation duration (t=3.49~3.565, p=0.002~0.003), and the reading rate (t=3.537~ 5.131, p=0.000~0.003).
The study is the first time to analyze students’ ocular movement by using Readalyzer in Taiwan, and it is also the first time to investigate the correlation between ocular movement and binocular visual function. Further onwards, researchers compared our data with English version, it appeared much difference between fixations, regressions, fixation duration, and reading rate. It meant that the patterns of reading Mandarin Chinese is very different from reading English or other alphabetic system. Moreover, we need to take notice of high proportion (83.74%) of abnormal binocular visual function.
