Validation of a theory about functions and effects of embedded support devices in distance education learning materials

In this contribution a theoretical model is explored and validated that describes and explains learning based on learning materials where the basic content is enriched with embedded support devices. Embedded support devices (ESD) are elaborations of the basic content of a course, intended to support students learning in a distance educational context. Examples are: questions with feedback, advance organizers and study guidelines. The model represents the interaction of a large set of variables and processes and has been tested using a variety of research studies, each focusing on specific interrelations and/or variables.

The research results support the positive impact of embedded support devices in written learning materials on study outcome. Furthermore the results indicate the impact of individual variables, such as prior knowledge and attitude towards computers. These variables influence the way students process the learning materials and/or use the task environment and have an interaction effect on study outcomes.
