In the present paper we describe the TEA system, a Computer Aided Education System for the teaching of Agrarian Economy. TEA is based on the courses hold in the Spanish School for Agrarian Foremen, during the last three years. This tutorial System follows the hypertext philosophy (in a wide sense, including textual and hypermedia information); this approach has been widely used in the educational field. In the development of TEA, we have tried to overcome the classical inconveniences of hypertext educational (disorientation during the navigation, cognitive overheads, etc) using graphical and textual ”clues” to improve user orientation. The system was developed on WWW, using the Mosaic User Interface and its Hypertext Mark-Up Language (HTML).
