Down syndrome (DS) children seem to have difficulties
in learning numbers compared to reading. They need customized
learning in numbers due to their slower pace of learning.
Unfortunately, there is limited theory to guide DS children to
learn and master in mathematics. With the advancement of
technology, the learning style of special children has been
improved from time to time from the paper and pen method, to
the use of computer application such as courseware to the latest
technology such as mobile application in smart phones and
tablets. As for now, there is no personalized mathematics
learning mobile application for DS children. The objectives of
this paper are to report on the development of a mobile
application on learning the basic numbers for DS children and to
evaluate the user acceptance on the developed mobile application.
The study will be focusing on the DS children with moderate level
of IQ who are learning to recognize basic numbers. The method
used to achieve the objectives is Rapid Application Development
(RAD). The mobile application was developed using Eclipse
Android Development Tool (ADT). An observation has been
conducted to 5 DS children who have different level of IQ. The
finding shows that the mobile application is really suitable for DS
children who have moderate level IQ.
