We are working on a method, called CEPIAH, for the design and the evaluation of pedagogical hypermedia. We propose a web based system used to help teachers to design hypermedia documents and to evaluate their prototypes. Having already elaborated a methodology for the evaluation of interactive pedagogical hypermedia (EMPI), the experience and the acknowledgement we have is able to upgrade the design help. To help the designer in his instructional Web site creation we developed an interactive guideline accessible on the Web. Three modules compose the guide: Evaluation Help, Design Help, and Predefined Models. We present as it follows a short description of the first and second modules.
