An investigation into the effects that digital media can have on the learning outcomes of individuals who have dyslexia

The effects that media can have on task performance have been greatly debated over the years. Whilst agreement has begun to emerge on the effects media have on cognitive performance, little is understood about the relationship between such media effects and individual differences such as individuals who have dyslexia. This paper presents findings from a study that investigated the effects computer-based media can have on the learning outcomes of individuals who have dyslexia. The purpose of the study was to obtain data that informed the development and design of e-learning and distance learning materials for universal use. The research process was based on Dual Coding Theory and refined by current theories on dyslexia. Findings from the research are intended to help academics and providers of e-learning materials to improve the design and delivery of their learning contents. ?? 2004 Elsevier Ltd.
