The creation and development of educational hypermedia by teachersand educational staff is often limited by their lack of computing skills, timeand support from the educational institutions. Especially the lack of computingskills is a hinderance to most of today¿s educational experts. Theproblem is to find out how those educational experts could be supported bycomputer based tools which are tailored especially to their needs withouthaving any technical limitations.In this study the separation of technical and educational content in educationalhypermedia is examined as a solution to this problem. The mainhypothesis of this study is that the separation of technical and educationalcontent is possible if it is based on a fine-grained structure of different teachingand learning strategies and their conversion into an authoring tool. Suchan authoring tool would make the creation of educational hypermedia veryeasy for teachers and therefore enable them to overcome the existing obstacles.The development of a new model, the creation of a new XML languageand the implementation of a new authoring tool form the basis for a detailedinvestigation. The investigation was done by undertaking several researchtasks like the evaluation of the XML language and the authoring tool by agroup of educational experts of different knowledge domains, the practicalusage of the authoring tool for the creation of real-life based educationalmaterial and the analysis of the gained research results.
