Resumen: In this work, the flipped classroom methodology has been applied to the laboratory sessions in the subject Physical Techniques I of the Degree in Physics at the University of Zaragoza, Spain. The proposed sessions have been distributed in 2 main parts. The first part consists on flipped laboratory sessions in which during the before-class sessions, the students must understand, design and customize the designs that will have to characterize experimentally in the laboratory sessions. The second part consists of a student contest activity where the students compete against their pairs while improving their learning about the topics presented in the flipped classes. The proposed approach could increase the depth of the acquisition of experimental skills, helping students to acquire a better understanding of the concepts under study in laboratory sessions.
