Mixed Usability Evaluation During the Development Cycle of “MEL-SindD”

“MEL-SindD” is an educational multimedia software for Down syndrome children. There is a lack of published research in the evaluation of appropriate user acceptance in educational software especially in supporting the needs of learning for disabled students. Usability refers to methods for improving ease-of-use during the design process of software. The complementary methods of usability testing and inspection have been used in order to obtain reliable data on usability of user acceptance of the software. The results suggested that no single usability evaluation method identifies all problems. Appropriate use of evaluation methods may significantly improve the quality in the ease-of- use of educational software to disable users.
