The researcher has derived a conceptual framework for the design and development of a computerized phonological treatment program, by adopting two bodies of literature: designing interactive multimedia system and phonological therapy. Developmental research methodology was adopted to develop the intervention system and to study the processes of development.
The purpose of the research is to investigate the use of technology in phonology intervention as a mode of learning to enhance delivery of treatment service to children with developmental phonological impairments by speech language-clinicians. In designing the multimedia system, special attention was given to the iterative stages of multimedia development cycle, the learning contexts, the use of storytelling, the criteria of phonological therapy, and the use of individualised instruction.
In the process of developing the system, a series of formative evaluation were carried out to refine the system before it was put into field test evaluation. At the same time the system was compared with another computerized treatment program, in order to have a deeper understanding in the design decision-making strategies.
The research results showed that children 4 to 7 years old could achieve generalization after the intervention. The results also indicated that the extent of parental support was equally important and effective as to the support provided by the speech-language pathologists. The significance of this research not only shed light on the effectiveness of the system, but also generated methodological directions for the design, development and implementation of such therapeutic tools for children with developmental phonological impairments.
