D-Lexis: Alphabet Mobile Learning Application for dyslexia for dyslexia Based on Slingerland Methods of Learning

This dessertation reports on the development of D-Lexis, a mobile application with android platform to help dyslexic students in alphabetical learning based on Slingerland methods of learning. Dyslexia is a medical condition that hinders reading, language and spelling skills of a student which affects their learning performance and makes dyslexic students hate conventional classroom methods. Therefore, learning modules for dyslexia learning must be in sequence, structured and applies multisensory approach with focus in alphabet learning as fundamental of literacy to overcome problems of phonological processing that leads to offences in reading, writing, memory retention and spelling.

The development of the system is based on rapid prototype methodology which is flexible for author to ensure the application meeting user's requirements. An interview with the dyslexia practitioners, 3 observations through videos, 5 qualitative surveys and 3 revisions on design of the systems are conducted to ensure the application is meeting requirements and needs of a dyslexic. The application is developed in 2 phase with 3 amendments on designs and 2 amendments on the development process which results in 5 interactive modules aims on enhancing writing and recognition of letters according to dyslexic needs and requirements. The proposed system is not only suitable for dyslexic but also can be used as a pre-literacy learning application for pre-schools students or primary students.
