We present a collaborative teaching model used in the practical classes of Manufacturing Engineering. This model has been developed by teachers from one of the Innovative Educational Groups "Nuevas Metodologias Docentes en Ingenieria Mecanica y de Fabricacion" (New Learning Methodologies in Mechanical Engineering and Manufacturing) at Universidad Politecnica de Madrid (UPM). It is implemented in the five degrees presently taught at the Escuela Tecnica Superior de Ingenieria y Diseno Industrial (ETSIDI) (Faculty of Engineering and Industrial Design) at UPM. In this model, traditional practical lessons are combined with a Web platform, developed on our own, named "Plataforma Educativa de Practicas Academicas" (PEPA) (Academic Learning Platform for Practical Classes), that allows both the automatic registration of the results from laboratory classes and the evaluations by teachers, automatically or manually.
