With the intention of producing a methodological change, introducing ICT and new educational practices such as peer learning and PBL (project based learning) in our schools to ensure that our students acquire good skills and competences that prepare them for their future life, the idea of proposing to our students a real challenge arose. The students, working in international leading teams, will conduct a real-like project about eating habits among teenagers at a European level simulating a current international team that we could find in any company or research university center.
