Adaptive Authoring of Adaptive Educational Hypermedia

In this paper we propose a set of guidelines for an adaptive authoring environment of adaptive educational hypermedia. This set consists of relevant and necessary functionalities of authoring systems (AS) for adaptive teaching and/or learning environments (LE). We extracted the core functionalities by analysing MyEnglishTeacher (MyET) and AIMS two independently designed and built AS for adaptable/ adaptive LE. The extended core led us to a conceptbased layered approach with respect to conceptand attribute-level adaptation, as well as lesson and presentation adaptation. We believe that providing adaptive authoring support for adaptive hypermedia will have a strong impact on the authorsí motivation and efficiency in performing their tasks and consequently will increase the popularity of adaptive hypermedia.
