Through the previous detection of existing learning styles in a classroom, a Virtual Learning Environment (VLE) has been designed for students of several Engineering degrees, using the Learning Management System (LMS) utilized in the University of Jaen, ILIAS. Learning styles of three different Knowledge Areas; Chemical Engineering, Materials Science and Environment Technology, have been analyzed. From learning styles detected in the classroom, the introduction of optional and compulsory activities to be developed by the student permits to develop the VLE. In this "optionality", the student can choose the activities more suitable to his learning style. As a consequence of the implementation of the virtual learning style, the assessment results must improve, as well as the students' motivation because they are selecting their particular learning way.
