The classes of Urban Planning of the ETSA are organized by four independent workshops in which teaching is not organized equitably, and each of them is free to mark both its aims and its methodologies. In order to know the differences on the part of the students, it has been decided to make a survey to the students of last course, who have been immersed in the program of flip teaching. All these affirmations encompass in a common denominator. This common denominator is the lack of motivation on the part of student body stressed by the absenteeism because of the theoretical lessons, which carry a difficulty added for the assimilation of the concepts. During the course different measures have been carried out to attack these problems. Adopting methods like the partial delivery, presentation or debates.
