The spread use of virtual learning environments presents a great potential for the development of applications which meet educational area needs. In view of the importance of a more dynamic implementation and that it will be able to continuously adapt to the students needs, it was proposed and developed the U-SEA (System of Teaching Adapted Ubiquitous). A software built on the basis of virtual learning environment Moodle, having as main purpose the adaptation to the computational context of the student, glimpsing characteristic techniques such as the environment suitability of the user's connection speed, provided with an infrastructure for Cloud Computing.
