A model for hypermedia learning environments based on electronic books

Current hypermedia learning environments do not have a common development basis. Their designers have often used ad-hoc solutions to solve the learning problems they have encountered. However, hypermedia technology can take advantage of employing a theoretical scheme - a model - which takes into account various kinds of learning activities, and solves some of the problems associated with its use in the learning process. The model can provide designers with the tools for creating a hypermedia learning system, by allowing the elements and functions involved in the definition of a specific application to be formally represented.DOI:10.1080/0968776970050302

Cognitive Load and Disorientation Issues in Hypermedia as Assistive Technology

Advances in information and communication technologies have raised the quality of inclusive education programs. Inclusive education, a recent advance in educational technology, has served to increase the ability of students with special needs. Hypermedia as an assistive technology has the potential to teach and train individuals with disabilities. However, like every technology, hypermedia itself is not problem-free. Disorientation and cognitive load are two of the most challenging problems related to hypermedia learning environments. The purpose of this chapter is to highlight disorientation and cognitive load problems in hypermedia learning environments where learners usually face a serious problem while navigating such environments.
