Nowadays, it gets more important than ever the use of ITs in learning. This is because as has happened during the whole history, teachers had to face pupils with different level of knowledge or different ages in the same classroom. Adaptive Educational Hypermedia Systems are aimed to solve these problems and to allow the teacher make a more personal version of the course for each student. With the authoring systems the teacher will be able to create an environment to teach the course that can be adapted to each student, showing him the parts or material that will be more useful for him, and that may be different from his partner material or parts of the course.
