This paper describes a University of Girona (Spain) project in which an interdisciplinary group has created an integrated platform for teachers to use to create and publish dynamic and interactive teaching materials that make use of new information technologies. Project objectives are summarized and an overview is provided of the functions of the two main modules of the platform: the Units Creation Module (UCM), which supports the creation of the didactic units by teachers, and the Units Navigation Module (UNM), the tool used to access the materials which are created using the UCM module. The following features of the UNM are then described in detail: the login procedure; user categories (supervisors, teachers, students, and guests); design of the main screen; and the function of each button, including navigation, help, information (bibliography, questions), tools (map of contents, note book, print, progress information), and communications (synchronous communication, teacher's mail, news). Two figures illustrate the main navigator screen, and the first main navigator screen. (DLS)
