Abstract

The purpose of the study is to identify the usability of OpenCouresWare(OCW) from the perspective of students with visual and hearing impairments. Twelve college students with disabilities(8 visual and 4 hearing impairment) implemented usability testing. Two modules in both edX and KOCW were selected for testing. Students with disabilities implemented usability testing and then each individual case was analyzed through quantitative and qualitative methods. As results, the degree of general usability in both edX and KOCW indicated an average level and the degree of accessibility in edX module was evaluated higher than KOCW. Specifically, the module of edX was rated highly by students with hearing impairments and the usability level of KOCW module was highly appreciated by blind students.

본 연구에서는 OCW로 제공되는 강좌가 시각, 청각 장애학생들이 인식하기에 사용성 측면에서 어떠한 장점과 문제점을 가지고 있는지를 파악하기 위해 사용성 평가를 실시하였다. 이에 시각장애 학생 8명, 청각장애 학생 4명으로 총 12명의 장애 대학생들을 선정하여 사용성 평가를 실시하였다. 사용성 평가 대상은 해외 edX와 국내 KOCW에서 제공하고 있는 강좌를 한 개씩 선정하여 실시하였다. 평가 결과, 일반적인 사용성 수준에서는 평균적으로 보통 수준을 나타내었는데, 장애인 접근성 측면에서는 edX가 KOCW 강좌보다 다소 높은 수준으로 평가되었다. 장애영역별로 살펴보면, 청각장애 학생들은 edX에서 제공하는 강좌에 대해 높은 평가를 하였고, 시각장애 전맹 학생들은 KOCW에서 제공하는 강좌에 대해 높은 사용성을 보이는 것으로 평가했다. 저시력 장애학생들은 두 강좌에 대해 비슷한 수준의 평가 양상을 나타냈다.
