: New Information Technologies (IT) offer a new way for teaching and learning. Rather than simply duplicate old learning materials and make them correspond to the new IT tools, it is essential to reconsider the learning process using computers. The authoring system MAI presents a new methodology for online learning based on an approach using concepts, dividing the course into “units of learning”, structuring the training with the help of a “navigation chart” and using media objects to illustrate the basic concepts. This authoring system is designed to support both creation of learning material and online learning.
