5.1. Methodological overview

The learning process that is designed for this subject is based on ...

  • 40 hours of interactive lecture class: the contents of each issue are discussed alternating theory with examples, issues and problems.
  • 5 hours of seminars: there are 5 sessions of 1 hour. The group is divided into 2 subgroups. Problems, doubts and applied exercises will be solved.
  • 15 hours of laboratory session: the practice group is divided into 5 teams. There are 5 different practices of 3 hours.
  • 8 hours of supervisal practical group. The studentsprepare and present a practice to the rest of the group.
