Abstract: This article reports on the application of general cognitive measures to describe and order the knowledge base of radiological images, aimed at the teaching of visual concepts through ITSs. The methodology adopted embraces the authoring process by means of software tools that aid the creation of appropriate teaching sequences which tend to cause a reduction in a student's learning time and to allow the use of various pedagogic strategies. We also present a case study to illustrate the use of cognitive measures in the teaching of brain lesions through CT scans of the head. Key-words: Authoring tools, Visual concepts, Radiological expertise. List of topics: Authoring shells and tools, Cognitive modelling, Knowledge elicitation. 1
