Hypermedia technology has a large spread in the instructional field, specially in Web-based educational environments. Adaptive hypermedia systems have been focused on such aspects as specifying user models to adapt the educational contents and the navigation structure providing learning paths. The work presented in this paper addresses a new aspect based on adapting the access to the didactic structures, that encapsulate educational contents and learning paths, to support useful educational adaptive applications. it is presented a framework to support the design process which is divided in two main parts: the first one is focused on instructional issues such as the organization of educational contents and the learning tasks to access them; and the second one is based on the translation of these instructional entities into hypermedia components, for which the Labyrinth hypermedia model is used.
