Dyslexia adaptive e-learning system based on multi-layer architecture

The key shortcoming of traditional e-learning systems is that the learning they promote is not adaptive. This paper analyses the e-learning activity of individuals with dyslexia and proposes an innovative design for an e-learning system. This new system is user-centric and interactive based on information about the user's learning preferences. The proposed system design employs a multi-layer architecture, including a presentation layer, an adaption layer, a learning management system layer, an application server layer and a database layer. The learning management system layer contains all the possible systems that provide resources to support the learning process, hence improving the system's reusability. The adaption layer provides the system's adaptive technique functionality, which makes it more intelligent and adaptive - the main objective of this research.
