The purpose of this study is to develop the Korean braille dictation learning system to improve the Korean braille orthographic ability of visually impaired students and to apply the system to the dictation class of visually impaired students to verify its effectiveness. Based on braille information instrument (HansoneⅡ) and C++ language, the Korean braille dictation learning system was developed from May to August 2010, and the developed system was applied to 40 students in year 4, 5, 6 at the schools for the visually impaired located at Seoul, Busan, Dajeon, Gangwon, and Chungbuk area from October 2010 to late February 2011. As the result of the study, the pre/post-assessment results for ‘sound-related’ among Korean braille orthography was found to have a statistically significant difference in the subdomains of vowels and palatalization, and the overall score. Second, the pre/post-assessment results for ‘form-related’ among Korean braille orthography was found to have a statistically significant difference in the subdomains of stem, ending, suffixed words, and abbreviations, and the overall score. Third, the pre/post-assessment results for ‘others’ among Korean braille orthography was found to have a statistically significant difference. Therefore, the Korean braille dictation learning system is regarded to have usage effects in all areas of ‘sound-related’, ‘form-related’, and ‘others’ in the Korean braille orthography.
