The objective of this study is to run a pilot test on the application of Open Science Schooling (OSS) methodology in projects with secondary-school students to know the impact it can have on their learning and their perception of it in addition to know how to develop teaching practice. As a study sample, we have selected a series of countries that are participating in an Erasmus+ project; to ensure a more exhaustive study, we are working with one of the participating schools located in Catalonia, near to our research group. In our study, we will consider the application of the Open Science Schooling methods in several secondary-school projects with the goal of comparing them and evaluating the method's versatility. We used questionnaires designed specifically for this project. The goal of OSS is to encourage schools to promote community well-being in cooperation with other stakeholders. It is very important the interplay of local, regional and global contexts and dynamics in shaping education and development. In one of the secondary schools students study the key role forests play in the fight against climate change, and the relationship of this natural resource with several Sustainable Development Goals (SDGs).
