The EXPLORE courses, organised by “EXPLORATORI: Natural Resources” project, are partcularly addressed to secondary school teachers and are conducted at Catalonia (North East of Spain). The main objectve is to provide secondary school teachers with the opportunity to explore the natural resources. Based on a combinaton of face-to-face and online learning, the programme of the courses uses an interdisciplinary approach, integratng Science, Technology, Engineering, and Mathematcs (STEM) and STEAM (STEM + art) felds. Data presented in this paper correspond to the 2012 and 2013 editons. The results, which were obtained from a writen questonnaire completed by teacher partcipants of EXPLORE courses, indicate that more than 70% of secondary school teachers were encouraged to introduce some course contents on their teaching classes afer partcipatng in an EXPLORE course.
