The subject has both a theoretical and practical character. Evaluation system The evaluation will be carried out through a set of commentary exercises, data analysis and case studies carried out individually by students in which the knowledge of the subject is put into practice. In this sense, a continuous evaluation can be considered, as the tasks carried out will be monitored periodically to comment on progress and difficulties. In the case of face-to-face students, this follow-up will be carried out directly in the workshops where the contact will be continuous. In the case of distance students, the work is of an individual nature, but the follow-up will be done through a weekly contact, both by phone and skype, where progress and interests and doubts can be raised.
