Development of Interactive Learning Materials in Engineering of Manufacturing Processes Hernández-Castellano, Pedro M.a *, Marrero-Alemán, M.
Students of the new degree in Engineering in Industrial Design and Product Development have participated for the elaboration of this work.
These technologies are those of the field of today’s engineering and are essential to achieve the so-called digital competence.
From the outset, we wanted the students to collaborate through the development of old Final Year Projects (FYP) of the degrees in process of closure, and new BDFP of the new titles of the Industrial and Civil Engineering School (EIIC).
Acknowledgments Thanks to the members of the GIE Manufacturing Engineering for their collaboration in this project of Educational Innovation.
