Abstract
This article shows the design and validation of two questionnaires addressed to students and teachers. The aim is to find out their perception about the competencies and learning outcomes for sustainability that students develop through their participation in the international cross-border project of the Bordeaux-Euskampus “Ocean i3: Blue Skills for the Development of the Blue Economy in the Basque-Aquitaine Cross-Border Coast”. The study population consisted of all the participants of the project: 37 students majoring in Biology, Law, Advertising, Business Administration and Management, Pedagogy, Criminology, Nursing, Engineering and Sports Sciences at the University of the Basque Country (UPV/EHU) and the University of Bordeaux (UBx), and 33 undergraduate and postgraduate lecturers from both universities. The article describes the procedure followed for their validity and reliability, and annexes both questionnaires. They may be transferable to other studies that share the same or similar objectives of this study.
